How to protect the concrete pump truck from injury when the weather is hot?

1. The maintenance method of the concrete pump truck should be in accordance with the corresponding requirements and methods in the maintenance manual, and the relevant items of the pump truck before and after use should be checked during daily use.

2. According to the corresponding requirements and methods in the use and maintenance manual, refer to the lubrication table to lubricate the pump truck parts in a timely and sufficient manner.

3. According to the corresponding requirements and methods in the use and maintenance manual, select the specified type of hydraulic oil, and regularly replace the oil used in the hydraulic system. 4. In accordance with the maintenance methods and requirements of the concrete pump truck in the manual, regularly check the water tank, concrete cylinder and concrete conveying pipe of the pumping system.

5. According to the corresponding requirements and methods in the use and maintenance manual, regularly check and adjust the torque of the fixed bolt of the rotating base of the boom. 6. According to the maintenance method of the concrete pump truck in the manual, regularly check and adjust the boom, rotating base, outrigger, support structure, reducer and other components.

7. Regularly check the working status of the hydraulic system and components, electrical system and components in accordance with the corresponding requirements and methods in the use and maintenance manual.

1. Control the terminal voltage according to the use of the pump truck itself. If the operation of the pump truck is in the daytime, the discharge situation is relatively short, and the charging time should be prevented from being too long; If the pump truck operates at night or starts the pump truck frequently, it will be easy to overdischarge, so it is necessary to increase the current when charging; It should be charged in time when parked for the next use.

2. The protection mode of the battery according to the temperature control when using the pump truck. If the weather is cold, it is necessary to keep the battery warm and choose the appropriate electrolyte density to keep the pump truck in a fully charged state. If you want to add distilled water, do it while charging to prevent freezing from occurring.

The engine should be warmed up before using the pump truck.

3. The battery must be maintained at ordinary times, if it is only used without maintenance, coupled with the poor working conditions of the battery, it will shorten the service life. For details, you can consult the Sanmin Heavy Branch.

After each time the concrete is finished, it must be cleaned, and it must be placed in a cool place on a hot day.

Which parts of the concrete pump truck can be maintained to make its life long.

How should the concrete pump truck maintain the pump truck all year round in the outdoor, exposed to the environment of the sun, the initiator is generally overheated, its long-term overtemperature working state, the gasket seal of the initiator is damaged, at this time you need to check, whether your initiator coolant can be lost, whether there can be a lot of dust on the heat sink, the formation of heat dissipation efficiency drop, etc. To deal with these problems, we need to stop and carefully inspect the initiator, ensure the quality and quantity of the coolant, liquidate the appearance of the heat sink, check whether the belt of the initiator can wear abnormally, clean the shell of the initiator, remove oil and dust, and ensure the normal heat dissipation of the appearance. The following initiatives would like to be adopted.

1) The coolant of the initiator must use the antifreeze on the right track, and the antifreeze must be within the validity period and the liquid volume must be sufficient. If there is a shortage of liquid due to a problem, the amount of water should not exceed 10% of the total coolant. In the hot climate, the water evaporates very quickly, and the pump truck works continuously during the peak period of summer construction, so it is not recommended to use water as the coolant of the initiator of the pump truck;

2) Before the spring flowers bloom, a layer of gauze should be installed in front of the radiator of the initiator to insist on the cleanliness of the radiator. Also, take care to clean the mesh regularly. After the arrival of summer, the gauze should be removed to facilitate the air activity of the radiator of the initiator;

3) After enhanced communication, try to improve the continuity of concrete supply and reducePump truck wear-resistant pipesIdle time in exposed environments.

2. Pay attention to the high temperature of the hydraulic oil.

How should the concrete pump truck maintain the ambient temperature in summer has been close to the lower limit of the normal working temperature of the hydraulic system of the pump truck, so the pumping work will inevitably form a rapid rise in the temperature of the hydraulic oil. As the temperature increases, the viscosity of the hydraulic oil will drop, resulting in a deterioration of smoothing effect. At the same time, the interference of hydraulic system components tends to increase under the action of thermal expansion and cold contraction, resulting in aggravated wear of components.

Therefore, the working temperature of hydraulic oil should be strictly controlled in a high-temperature environment. The main concerns and measures are as follows:

1) In the temperature environment of about 35, 46 anti-wear hydraulic oil should be selected; If the temperature exceeds 35 for a long time, 68 anti-wear should be used.

How to maintain and maintain the concrete pump truck before each start and after pumping to clean the whole vehicle, and then check and insist that the manual smooth grease pump oil storage tank is filled with smooth grease, pull the handle of the smooth grease pump, and inspect the stirring bearing, S tube size shaft head, if there is clean grease overflow. During the working process, the manual smooth grease pump handle should be wrenched in 10 times every 1 hour. At the same time, the smooth system is kept clean to prevent dust and other impurities from enteringPump truck wear-resistant pipes, do not come into contact with acids and alkalis, and stop cleaning the system every 500 hours of operation.

How to maintain and maintain the concrete pump truck 2, the oil cup is smooth.

On the cylinder seat of the two swing valves, there is a smooth oil cup in each. Before the pumping work begins, it is necessary to fill the oil cup with grease and screw the cap to stop smoothing. During the working process, the cap should be smoothed every 4 hours to make the spherical friction surface in a good smooth state.

3. Concrete piston.

How to maintain and maintain the concrete pump truck When the plating (mm) of the escort cylinder is not worn off and the rear part of the concrete piston, that is, the water tank, presents concrete slurry or sand particles, it indicates that the piston has been worn and needs to be replaced immediately with the concrete seal, guide ring and dust ring. Because the piston can be retreated to the pumping system water tank through the simple operation on the control panel, so the piston should be often withdrawn from the inspection, in addition, after the piston retreats to the water tank, the concrete seal body and the guide ring on the piston should be stopped from cleaning, and at the same time coated with lithium grease smooth, so that the piston service life can be effectively prolonged.

Key points of concrete pump truck maintenance.

The piston commercial concrete boom pump truck is the main component of the boom pump truck, and its main wearing parts are three, namely commercial concrete cylinder, piston and distribution valve.

1. Replacement of commercial concrete cylinders.

When the inner wall of the commercial concrete cylinder is scratched or worn, it is generally taken out for repair, or used as a U-turn. In order to facilitate the maintenance and replacement of the commercial concrete cylinder, we can set a movable door cover at the bottom of the commercial concrete hopper, and the opening and closing of this movable door cover can be completed by the movement of the oil cylinder, and at the same time, the commercial concrete cylinder can also be pulled out from this opening. After adopting this new type of structural mode, when the replacement of the commercial concrete cylinder in the past is changed, it is necessary to use lifting equipment to lift it out for maintenance, and the labor intensity is greatly reduced.

2. a piston. Once the piston is worn, then it will lead to a significant reduction in the sealing of the inner wall of the commercial concrete cylinder and the piston, and even the problem of slurry leakage may occur, in addition, the pumping capacity of the piston commercial concrete boom pump truck will also be reduced because of the piston wear, this is because the commercial concrete suction force entering the commercial concrete cylinder will be reduced with the piston wear, if we find this situation, then it should be effectively repaired in time.

To facilitate access to the piston, a hydraulic circuit can be used to move left and right to place the piston ejection on the access frame. In addition, it often happens that in the process of piston replacement operations, the operator's fingers are cut or even cut off by the boom pump truck because the piston commercial concrete boom pump truck is not stopped (the engine is still running). Therefore, when carrying out piston maintenance, it is necessary to pay attention to first release the pressure accumulated in the hydraulic circuit, and then stop the operation.

3. Lubrication system.

The lubrication system is the main part of the maintenance of the piston commercial concrete boom pump truck, especially for the rotary part, the timely supply of lubricating oil to the parts such as hopper, commercial concrete pad and distribution valve is extremely important. In addition, special personnel should be arranged to regularly inspect the consumption of lubricating oil in important parts, and once the lubricating oil is found to be insufficient, then it should be replenished in time.

4. a distribution valve.

As we all know, there are not many components of the distribution valve, only a few main components. If the distribution valve component is damaged, then in order to effectively improve the performance of the boom pump truck, the most reasonable and simple way is to replace the distribution valve directly. At present, there are three categories of distribution valves, namely tubular swing valves, rotary valves and gate valves, and the application of rotary valves and gate valves is less, while swing valves are the most widely used and are the current mainstream.

The oscillating valve is mainly composed of three parts: the oscillating tube, the cutting ring and the glasses plate.

The problem of concrete pump truck blocking pipes, I believe that those who have worked as pumpers have encountered it, and it is also the last thing that everyone wants to encounter.

But when it comes to it, why is it blocked? The following is an analysis of the following.

1. The concrete in the pump pipe of the pump truck has not been pumped for a long time.

This may be that the connection time between the mixer truck and the mixer truck is too long, after the last mixer truck is unloaded, the next mixer truck takes a long time to come, which causes the concrete to not move in the pump pipe for a long time, which is easy to cause concrete segregation, and most of the pump blockages are due to this reason.

2. The workability of concrete is not good.

The workability of concrete includes some parameters related to the working properties of concrete, such as fluidity and water retention of concrete, and the workability is not good, the fluidity of concrete is very poor, too dry or too wet is not good, it is easy to cause the concrete cylinder material of the pump truck to be emptied, and, due to the poor workability, the resistance of concrete in the pump pipe is also greater, so it is easy to lead to pipe blockage.

However, the workability of this concrete is mainly determined by the ratio, and the weather will also cause the moisture content of the sand and gravel to change, which will affect the workability of the concrete.

3. Serious wear of the piston of the pump truck.

The piston of the concrete cylinder is seriously worn, which will lead to the poor absorption of the concrete, and will also lead to insufficient pumping pressure, and the water in the concrete will run into the middle water tank, resulting in poor fluidity of the concrete.

4. The angle of the boom of the concrete pump truck.

This reason many people may not think, when working, try to ensure that the boom of the concrete pump truck is all, in an arc shape, do not keep the boom folded when the pump truck is working, so that it is easy to cause the elbow pipe at the junction of the boom and the boom to have an angle, which increases the resistance of the concrete in the pump pipe, and there is the vertical downward pipeline of the pump truck, or the vertical upward working condition, it is necessary to install a fortified segregation device to prevent the situation of pipe blockage.

The above are some of the reasons for the blockage of the pump pipe of the concrete pump truck, so, how to prevent these things from happening? As long as you follow the above reasons to find out, it is not difficult to find that as long as it is not in the above cases, it is still difficult to block the pipe.

At present, there are many leading companies for concrete pump trucks, when choosing concrete pump trucks, concrete pump trucks are not as expensive as possible, nor is it cheaper the better, and the best factors that should be considered are as follows:

1 Type of construction.

In addition to giving priority to the amount of concrete pouring when selecting the model, the type and structure of the construction building, the construction requirements, the construction site conditions and the surrounding environment and other influencing factors should also be considered. Under normal circumstances, the main performance parameters of the concrete pump truck should be consistent with the construction needs or slightly larger, if the equipment capacity is too large, then the equipment utilization rate is relatively low; If the capacity is too small, it will not only fail to meet the construction requirements, but will also accelerate the loss of the concrete pump truck.

2 Construction business volume.

Generally, the number of concrete pump trucks used can be calculated according to the amount of concrete pouring, the actual conveying volume of a single machine and the construction operation time. For those concrete pumping construction projects with a large amount of one-time concrete pouring, in addition to being determined according to the calculation, there should also be a certain amount of reserve, and 2-3 concrete pump trucks need to be equipped.

3 Product Configuration.

The product performance of concrete pump truck should adhere to a high starting point when selecting. If a high-value coagulation pump truck is selected, the standard requirements for its products must also be improved. The quality of the main components of the product, from the internal quality to the appearance quality, should be adapted to the first value of the whole vehicle.

Insist on choosing high-quality pump trucks, it is necessary to consider many factors, such as the comprehensive strength of the manufacturer, the configuration of concrete pump trucks, the technology adopted, after-sales service and so on.

4 Powertrain.

Usually the concrete pump truck adopts full hydraulic technology, so the first thing to consider is whether the hydraulic technology used is advanced, the quality of the hydraulic components, because the power of the concrete pump truck is the first to start the motor, so in addition to considering the engine performance and quality, but also consider the performance, bearing capacity and quality of the automobile chassis. If it is used for new rural construction and the road is relatively narrow, it is also necessary to consult the width of the chassis and whether it can pass through the narrow road or small construction space normally.

5 Operating System.

The operation control system on the concrete pump truck is equipped with manual, wired and wireless control mode, wired control is convenient and flexible, wireless remote control can be operated from a distance, once the circuit fails, manual operation mode can be adopted.

6 Boom system.

Construction safety has always been the first consideration of construction, the boom system of concrete pump truck is an important factor affecting its safety, when buying concrete pump truck, you need to consult the boom material of the pump truck, or go to the manufacturer to directly check the actual situation of the boom.

7. After-sales service.

As a special vehicle, the concrete pump truck should be required for construction safety, mechanical performance, after-sales service and accessories of the manufacturer because of its special functions. Once a construction accident occurs, it will not only affect the construction progress, but also have unimaginable consequences. Therefore, before the purchase of concrete pump trucks, we must ask the question of after-sales service, if there is a problem after the purchase, it is best to provide after-sales service to the professionals of the manufacturer, and do not deal with it without authorization, so as not to cause unnecessary losses.
