There are several kinds of concrete mixer trailer pumps, which are suitable for what kind of constru

There are two types of mixer trailer pumps: diesel power and electric power.

The diesel-powered mixer trailer pump T9 is a 4-cylinder 62 kW diesel engine directly with oil pump, and the oil pump drives concrete conveying, concrete mixing, and lifting of sand and gravel hopper. The whole machine does not need three-phase electricity. It is suitable for operation in places where there is no three-phase electricity in the field, or where the three-phase electricity is unstable.

Electrodynamic mixing Trailer pump T8, the main motor is 30 kilowatt tubular concrete conveying, 2 4 kilowatt mixing motors, 1 kilowatt hopper lifting motor, many rural three-phase electricity can be connected.

There are two kinds of concrete mixer trailer pumps, but they can be divided into three types, with a total power of about 44kw, and the voltage in rural areas can be used, 380v.

1. Mixer trailer pump K5 is suitable for building floors, inclined roofs, factory floors, railway bridges, water conservancy dams, and highway construction.

2. The truck-mounted mixer trailer pump K6 is the same as above, but it is driven by diesel and electric power, with a car chassis, so it is more convenient to move, and it is also convenient to move where there is no electricity.

3. The compulsory mixer trailer pump is more suitable for large-scale projects, and it is also more expensive.

If it is used in rural areas, the first type is generally OK, ** lower, and can fully meet the rural construction conditions, Huilong's hydraulic stirring trailer pump, cost-effective, you can take a look.

Concrete mixer--- cement, coarse and fine aggregates, admixtures, water and other materials are matched according to a certain proportion (metering), and by machinery, within the corresponding set time, it is mixed into a mixture (i.e. concrete) equipment.

Concrete trailer pump --- is the equipment for transporting concrete horizontally and vertically at the construction site.

In addition, according to the relevant information, there is now a "tow mixer pumping machine", such as Hunan Minhe production equipment is to combine concrete mixing and pumping into one, which can be consulted on the Internet.

Its principle is actually relatively simple, and the coarse principle is relatively simple, just like a syringe for injection, sucked in and then punched out. Two concrete cylinders, one sucking and one dozen, work alternately with each other.

First of all, it has to be loaded, and the material is put into the mixing tank, which is driven by a motor to operate, and the mixed concrete is poured into the hopper. The material in the hopper should enter the conveying cylinder, and the conveying system is powered by the hydraulic system, and the conveying cylinder is pushed through the oil cylinder, and the concrete is pumped out by sucking one by one.

The concrete mixer trailer pump is composed of professional equipment and devices that combine concrete mixing and pumping. Among them, the structure of parts and components mainly includes hydraulic system, control mechanism, mixing device, reducer, cleaning system, etc. The working principle is to take out the power of the engine of the power take-off device, which will drive the variable pump of the hydraulic system, convert the mechanical energy into hydraulic energy and transmit it to the quantitative motor, and then the motor will drive the reducer, and the reducer will drive the mixing drum device to mix the tank concrete, and then pump the concrete with the conveying system.

The mixing drum is a loading container for concrete. In the process of feeding and transportation, the mixing drum is rotating, and the concrete is moving inward along the blade, and when discharging, the mixing drum rotates in reverse, and the concrete is discharged outward along the blade.

In fact, its work is very simple, as long as it is used reasonably and regularly maintained, there will be no breakdowns.

The working principle diagram provided by Woyu Machinery concrete pump manufacturer, the hydraulic system pushes concrete to achieve concrete pumping.

Minhe Heavy Industry T6 has the same principle as ordinary mixer, and is one of the major systems of mixer trailer pump. The conveying of concrete is mainly completed by the conveying system of the mixer trailer pump, which is controlled by the electronic control system.

The concrete mixer pump drives the hydraulic pump through the motor, and the hydraulic pump drives the hydraulic cylinder, pushes the piston in the conveying cylinder, and carries out the alternating movement of "one push and one suction", sucks the concrete from the hopper into the conveying cylinder, and pumps it out, and the process is controlled by the hydraulic valve and switched by the swing cylinder in the distribution system.

Hopefully, you will benefit from the following frequently asked questions about mixer tow pumps:

In the process of using many construction machinery and equipment, there may be a variety of problems, sometimes caused by mechanical failures, signal transmission, human factors, etc., requiring operators and maintenance personnel to deal with problems with high speed and high quality, so as not to affect production. The following concrete mixer pump company Sanmin Heavy Industry has summarized several common problems and treatment methods in the use of mixer trailer pumps!

1. The engine speed decreases.

The first thing to do is to test the engine itself, if the engine output is lower than the rated power, it may be poor fuel quality, low fuel pressure, faulty brakes and levers, and turbocharger deposits. If the engine output is normal, it is necessary to see if there is a mismatch between the flow rate of the hydraulic pump and the output power of the engine. Such faults should start with the electrical system, then check the hydraulic system, and finally check the mechanical transmission system.

2. The working speed slows down.

The slowdown of the mixer trailer pump is mainly due to the decline of engine power and the leakage of the hydraulic system caused by the wear of all parts of the machine. After working for a certain period of time, the internal hydraulic components of the pump (cylinder block, plunger, nine-hole plate, etc.) will inevitably produce excessive wear, which will cause internal leakage and uncoordinated data of various parameters, resulting in insufficient flow and high oil temperature and slow working speed. At this time, it is necessary to overhaul the whole machine and repair and replace the parts that are worn out of limit.

The AUID (Automatic Idling) technology of the mixer trailer pump effectively controls fuel consumption and engine wear, and the variable pump control system has higher accuracy and improved efficiency!

3. The solenoid valve does not work.

When controlling the solenoid valve on the operation panel, the solenoid valve cannot be opened manually or automatically, and the solenoid valve coil or pilot valve or operation button can be replaced; If it cannot be opened manually, when the air outlet on the solenoid valve is exhausted, replace the solenoid valve; If it cannot be opened manually, when the outlet under the solenoid valve is exhausted, check whether the inside of the cylinder, the sealing ring, the piston rod, and the hold-down screw are leaking;

4. The belt conveyor and cylinder do not work.

When the belt is running, it is necessary to check the operation of the roller frequently, and replace it in time if it is found that it does not turn, and cannot work with illness, otherwise it will cause the belt to be scratched; The lubricating oil of the electric drum of the belt conveyor should be checked regularly, added and replaced in time. Dismantle and inspect to remove the sludge inside the cylinder.

5. Daily maintenance of the mixer trailer pump In order to prevent the failure of the excavator, it is necessary to pay great attention to the maintenance of the mixer trailer pump in the daily use process. Moreover, the maintenance and maintenance of the mixer trailer pump should be carried out in strict accordance with the operation instructions, if the maintenance is improper, it may lead to seal damage, resulting in slurry leakage or damage to other components.

The boom pump is also a concrete sky pump, and the structure is divided into the following points:

1. The boom system is composed of several parts, such as multi-section boom, connecting rod, oil cylinder and connector. For example, the boom pump Jinniu T8 produced by Taurus Heavy Industry has three booms. The specific is also determined according to the length.

2. The chassis is composed of several parts, such as automobile chassis, PTO (transfer case) and auxiliary beams. The boom pump trucks of Taurus Heavy Industry are all made of Sinotruk ace chassis, which has strong power and guaranteed chassis quality, so that you can rest assured!

3. The turret above the boom is composed of several parts, such as a turntable, a slewing mechanism, a fixed turret (connecting frame) and a supporting structure.

4. The pumping system is composed of six parts: pumping mechanism, hopper, S valve assembly, swing mechanism, stirring mechanism, piping assembly and boom piping.

5. The hydraulic system is mainly divided into two parts: the pumping hydraulic system and the boom hydraulic system: the pumping hydraulic system includes the main pumping oil circuit system, the distribution valve oil circuit system, the mixing oil circuit system and the water pump oil circuit system. The boom hydraulic system includes three parts: boom oil circuit system, outrigger oil circuit system and rotary oil circuit system.

The hydraulic system is mainly composed of hydraulic pumps, valve groups, accumulators, hydraulic motors and other hydraulic components;

6. The electrical system is mainly composed of control cabinets, adapters and other electrical components.

Inquiries about second-hand pump trucks can be seen on the "concrete housekeeper".

1. Before the start of pumping, the operator of the hose communicates well with the pump opening personnel, the bending radius of the front hose should be greater than 1m, and the operator is not allowed to stand at the outlet of the pipe to prevent the concrete from suddenly spraying out and hurting people.

2. The hose of the concrete mixer pump should be fixed and solid. It is strictly forbidden to bend the hose of the agitator pump to avoid the hose**. This is also one of the reasons why the mixing pump is blocked, when the pipeline is blocked, when pumping after treatment, the end of the soft joint will swing rapidly, and the concrete may be sprayed instantaneously, and the staff must not approach the hose.

3. Pay attention to standing in the corner of the building when operating the hose of the concrete mixer pump, because the hose is soft, there may be shaking or concrete spraying when pumping concrete, which may lead to the danger of falling.

The material of the mixer trailer pump for pumping concrete is generally selected when it comes to itIt should be analyzed from several angles, including the type of brand, the size of the specification, the scope of use, and so on。Usually ordinary concrete is composed of sediment, water, mud and stone, etc., which has very strong advantages, such as very low cost, strong plasticity, good durability, can resist various changes in the external environment, whether it is high or low temperature, can reduce the corrosion and deformation of materials.

InWhen choosing a concrete material, it is necessary to analyze it according to the local brand。Because the current cement brands are indeed diverse, if inferior materials are found, it may be difficult to guarantee the effect, and there is no way to use them normally in the future. But if you can find a high-quality material type, although it is a little more expensive, it can generally play a good role, and it also has higher strength, and the scope of application is more extensive, which can meet everyone's needs.

Size is also a very important consideration。If you choose a size that is too large, it may be particularly inconvenient to use your own space, which will cause waste in the future. However, if you use too little, it may affect the quality of your home environment in the future.

Therefore, when choosing concrete materials, different specifications and sizes have different sizes, and they are also suitable for different areas.

Cement slurry can play a lubricating role, but also has a strong viscosity, and after hardening, it will form a solid whole. So everyoneIt is necessary to pay attention to the hardness of the material, if the hardness is not too strong, there will be many problems in the process of future use, including sediment falling off and so on。Therefore, it is necessary to pay attention to these important selection precautions and considerations, and make a comprehensive selection.

This is to ask professional people, and there is generally a specific ratio.

The relevant staff will tell you professional selection tips.

Ask the decorator and he will tell you about this expertise.

Look at you guys. It's generally iron, you can ask. Now there are a lot of options.

Just choose according to the conventional, don't choose too many redundant and complicated.

I asked the person in charge of the renovation about this, I don't know about this knowledge.

Mixing pump is also known as mixing pump, English: mixing pump

Mixer trailer pump is a small concrete pump that adopts a fully automated construction operating system and integrates feeding, mixing and mixing, and high-pressure pumping. The pump is simple to operate, stable in performance and easy to move.

First of all, it is necessary to reduce the various corrosive effects. The phenomenon that the metal surface of the concrete trailer pump undergoes a chemical or electrochemical reaction with the surrounding medium and suffers damage is called corrosion of Raymond mill. This corrosive effect will not only affect the normal operation of the concrete pump, but also corrode the internal parts of the machinery.

In use, management and operation personnel should take effective measures according to the local weather conditions and air pollution at that time, reduce effective measures, reduce the impact of chemical corrosion on machinery, and focus on preventing the invasion of rain and chemical components in the air into machinery.

The second is to reduce the impact of temperature. When the concrete pump and the concrete trailer pump are operating, the temperature of each component has its own normal range. In the process of use, it is necessary to prevent overload operation at low temperature, ensure the normal operation of the low-speed pre-heating stage, and make the machinery reach the specified temperature before driving or working; Second, to prevent the concrete pump from running at high temperatures, the value on the various temperature gauges should be checked frequently during the mechanical operation, and the problem should be stopped immediately for inspection, and the fault should be eliminated even if the roller is broken.

For those who can't find the reason for a while, they must not work with the machine without treatment.

Finally, the impact of continued impurities should be reduced when using a concrete trailer pump. Impurities of concrete equipment generally refer to non-metallic substances such as dust and soil and some metal chips and wear products produced by construction machinery during use. Once these impurities enter the inside of the machinery and reach between the mating surfaces of the machinery, the harm is very great, which not only makes the relative movement out of the block, accelerates the wear of the parts, but also scratches the mating surface, destroys the lubricating oil film, increases the temperature of the parts, and deteriorates the lubricating oil.

Therefore, for construction machinery working in harsh environments and complex conditions, it is necessary to use high-quality, supporting parts, lubricating oil and grease to block the source of harmful impurities; Second, it is necessary to do a good job in the protection of the concrete pump at the work site to ensure that the corresponding mechanism can work normally and prevent various impurities from entering the machinery.
