How to debug and operate the rotary blower?

Check that the oil in the tank is up to standard. Before starting the rotary blower, please take off the air inlet filter and pour about 30ml of oil into the main engine, so that the oil is evenly distributed inside the rotary blower (rotate a few times by hand). Check whether the tightness of the V-belt is appropriate, if it is too loose, please adjust it.

Check whether the safety valve is set at the specified pressure position, such as the working pressure; The opening pressure of the safety valve is. During the test run, the exhaust valve can be manually adjusted to the opening pressure, and the safety valve can be adjusted to open exactly (the pressure is multiple of the working pressure).

Precautions for installation of rotary blower:

1. The fan should be installed horizontally.

2. It is best to install sound-absorbing materials around the inner wall of the computer room to reduce noise.

3. Be careful not to screw down the check valve when taking over (the protruding part of the check valve should be facing up).

4. Please connect the distribution line correctly and pay attention to the motor steering and fan rotation direction marking.

5. The diameter of the gas distribution pipe should not be less than the exhaust diameter of the fan, and pay attention to the cleanliness of the pipe, and the air supply pipe should be installed above the water surface to prevent the pressure from being too large when starting caused by water entering the pipe.

6. There should be a vent in the fan room and a ventilation fan should be installed, and the vent should be located in the upper and lower places to facilitate air convection, so as to prevent the temperature in the machine room from being too high and affecting the normal operation of the fan.

7. Please pay special attention to safety when handling the fan, avoid the fan being bumped and impacted, and do not hold the fan upright to prevent the lubricating oil from pouring out of the oil tank.

Summary. The switching time of the rotary blower needs to be determined on a case-by-case basis. Here are some factors that can affect the switching time of a rotary blower:

1.Process requirements: rotary blowers are usually used to convey and handle dust, particles and other materials, according to the process requirements, it may be necessary to process different materials in different time intervals, so it is necessary to determine the switching time according to the requirements of the process.

2.Material properties and processing capacity: Different materials have different properties and processing requirements, such as density, particle size, humidity, etc., these factors will affect the treatment effect and energy consumption of rotary blowers.

At the same time, the throughput can also affect the efficiency and longevity of the equipment. 3.Models and parameters of rotary blowers:

The model and parameters of the rotary blower will affect the performance and use of the equipment, such as motor power, speed, diameter of inlet and outlet, length of the bowl, etc. Rotary blowers of different models and parameters may require different changeover times to achieve optimal processing and energy consumption.

How often to switch.

The switching time of the rotary blower needs to be determined on a case-by-case basis. Here are some factors that can affect the switching time of a rotary blower:1

Process requirements: rotary blowers are usually used to transport and process dust, particles and other materials, according to the process requirements, different materials may need to be processed in different time intervals, so it is necessary to determine the switching time according to the requirements of the process cavity. 2.

Material properties and processing capacity: Different materials have different properties and processing requirements, such as density, particle size, humidity, etc., these factors will affect the treatment effect and energy consumption of rotary blowers. At the same time, the throughput can also affect the efficiency and longevity of the equipment.

3.The model and parameters of the rotary blower: The model and parameters of the rotary blower will affect the performance and use of the equipment, such as motor power, speed, inlet and outlet diameter, drum length, etc.

Different types of rotary blowers with different numbers and parameters may require different changeover times to achieve the best treatment results and energy consumption.

In general, the switching time of a rotary blower can range from a few minutes to a few hours. For example, in some mines and mineral processing sites, depending on the type and characteristics of the imitation material, the changeover time of the rotary blower may be around 10 minutes. On some chemical production lines, the changeover time of the rotary blower may take longer, which can last for several hours or even more than a day.

Hello, the rotary blower will generally be switched according to the load demand and safety operation regulations, the stool return room is determined by the load during the switching, the general time is between a few seconds and a few minutes, and it needs to be determined according to the specific situation. Secondly, the switching time of the rotary blower depends on the use and configuration of the equipment. Under normal circumstances, the switching frequency of the rotary blower should be switched once an hour to ensure the safe operation of the jujube blower equipment.

If it is used in a polluted environment, the switching frequency can be decided according to the environment, such as every 30 minutes.

The blower runs eccentrically on the rotor offset in the cylinder, and the volume change between the blades in the rotor groove sucks the air in, compresses, and discharges. During operation, the pressure difference of the blower is used to automatically send lubrication to the drip nozzle and drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from backflowing.

The rotary blower belongs to the constant flow fan, the main parameter of the work is the air volume, the output air volume changes with the change of the pipeline and the air volume, and the air volume changes small;

Rotary blower is variable capacity compression, low speed, low noise, low vibration, high efficiency and high energy saving.

1.Small size, large air volume, low noise, energy saving, rotary blower adopts the principle of running compressed air, although the volume is small, but the air volume is large, energy saving, and silent operation is incomparable with other forms of fans.

2.Stable operation, easy installation, as long as the small model is properly placed, the vibration is very small, no need to install anti-vibration device, easy to install.

3.Resistant to load changes, stable air volume. For example, if the pressure of the sewage treatment aeration tank changes, the load changes, but the air volume changes little with the change of pressure.

4.Equipped with an air chamber for stable air dispersion, all models are equipped with an air chamber to prevent air pulsation and smooth air dispersion.

5.The material is excellent, the structure is ingenious, the performance is excellent, the blower is all made of high-quality materials, the structure is exquisite, durable, excellent performance, and the long-term use of the fault is less;

The reasons for the insufficient air volume of the rotary blower are:1If there is an air leakage, air leakage or random cracks and air leakage on the fan air duct, pipes, and oil ducts, please check the fan oil circuit system and pipes.

2.If the belt slips and becomes loose, please adjust the tightness of the belt.

3.If the lubricating oil of the wind source is missing or the quality of the oil is deteriorated, please check the lubrication system of the fan, including the drip nozzle and oil filter, and replace or replace the specified lubricating oil.

4.The inlet filter of the fan is blocked, which affects the air intake of the fan, please clean the filter sponge. The after-sales commissioner of Jingong rotary blower reminds you to regularly check the oil quantity and belt tightness, pay attention to abnormal changes in pressure, and clean the air filter in time to prolong the service life of the rotary blower.

The rotary fan is good, we love to use the sewage treatment plant, and recommend two brands to the landlord, Changfeng and Jingong, which are now used, good.

Probably. Blower.

If there is always a problem, it is recommended to choose Jingong or Pepsi, these two brands of blowers generally rarely have problems.

Hello! Rotary blowers need to pay attention to the usual maintenance, the focus is not to lack oil. Because the impeller and the side wall of the air chamber are in contact with each other, when there is little or no oil, dry friction will occur, and the noise will be abnormal.

If in order to improve the use of the experience, you can choose to use a Lu blower (roots blower), reduce the failure rate, reduce the workload of personnel maintenance, choose a better quality brand, the same can achieve the effect of reducing noise, because the fan is compressed without contact, the air is purer, even if the bearing is replaced in the years, there is no need to return to the factory for machine tool processing, reducing user trouble. The principle is shown in the figure

Successful case: Shishi City, Fujian Province Nanyang for the stock ****, rotary blower replacement of Juhong Lu's blower.

1. Inspection of lubrication system.

2) Check whether the hydraulic oil is mixed with water and other dirt and deteriorate daily, if it deteriorates, please replace the hydraulic oil in time.

3) Check whether the dripping condition of the dripping nozzle (15-20 drops per minute) is normal daily, and observe whether there is lubricating oil flowing in the transparent oil return pipe, if the dripping nozzle is dirty, you can remove the adjustment screw for cleaning.

2. Inspection of belts.

After the rotary blower has been running for a while (about a week or so), the belt will elongate. At this time, the fixing bolts of the motor should be loosened, the motor should be moved, the belt should be tightened in a suitable position, and then the motor fixing bolts should be tightened, and it should be noted that the end faces of the motor pulley and the fan pulley should be on the same plane. At the same time, check whether the jacking screws of the two pulleys are loose, if they are loose, please tighten them.

3. Check the air filter.

Clean the filter sponge in time, and working for a long time may cause the inlet filter of the fan to be blocked, affecting the air intake of the fan.

4. Always check the flexible condition of the safety valve, if it is not flexible, please clean and debug to ensure reliable opening and closing.

5. Check whether there is oil leakage or air leakage and repair it daily.

6. Clean the fan room daily, keep it clean and well ventilated.

The use environment should always be kept clean and tidy, the surface of the fan should be kept clean, and there should be no sundries at the air inlet and outlet. Regularly eliminate dust and other debris in the fan and pipe; It can only be operated under the condition that the fan is completely in gear, and at the same time, the capacity of the power supply facilities should be kept sufficient, the voltage should be stable, and the operation of the lack of phase is strictly prohibited, and the power supply line must be a special line, and the temporary line should not be used for a long time to supply power; During the operation of the rotary blower, if it is found that the fan has abnormal sound, the motor is seriously heated, the shell is electrified, the switch trips, and cannot be started, it should be stopped immediately for inspection. In order to ensure safety, it is not allowed to carry out repairs during the operation of the wind turbine.

After overhaul, test operation should be carried out for about five minutes to confirm that there is no abnormal phenomenon before starting the operation; According to the use of environmental conditions from time to time to the bearing to supplement or replace the grease (motor enclosed bearing in the service life does not need to replace the grease), in order to ensure the good lubrication of the fan in the process of operation, the number of refueling is not less than 1000 hours, closed bearing and motor bearing, refueling with zl 3 lithium grease to fill the inner and outer rings of the bearing 2 3It is strictly forbidden to run without oil; The rotary blower should be stored in a dry environment to avoid moisture on the motor. When the fan is stored in the open air, there should be rainproof measures.

In the process of storage and handling, the fan should be prevented from bumping to avoid damage to the fan.
