Fluorine pump is a kind of fluid conveying equipment widely used in chemical, pharmaceutical, environmental protection and other fields. Its repair and maintenance is very important to ensure the normal operation and prolong the service life of the equipment. The following will detail the repair and maintenance methods of lining fluorine pump.

1. maintenance

1. Disassembly and inspection

In the maintenance of the lining of the pump, the first need to disassemble the pump, check the impeller, pump casing, shaft and other parts of the wear, especially the wear of the fluorine plastic lining. If the wear is serious, it needs to be replaced.

2. Tightness inspection

Check the sealing performance of the pump, including mechanical seals and packing seals. If leakage is found, the seal shall be replaced in time.

3. Bearing inspection

Check the wear of the bearing, if the wear is serious, it needs to be replaced. At the same time, it is necessary to check the lubrication of the bearing to ensure that the bearing is well lubricated.

4. Electrical inspection

Check the insulation performance and wiring of the motor to ensure the normal operation of the pump.

2. maintenance

1. Regular inspection

Regularly check the lining fluorine pump, including the performance of the pump, the wear of the fluorine plastic lining, etc., and deal with the problem in time.

2. Cleaning and lubrication

Keep the pump clean and avoid impurities entering the pump. Regularly lubricate the bearing to ensure the normal operation of the bearing.

3. Seal maintenance

Keep the seal clean and check the wear of the seal regularly. If it is found to be worn, it should be replaced in time.

4. Fluid control

Ensure that the delivered fluid meets the scope of application of the pump and avoid conveying media that are corrosive to the pump. When the machine is stopped, the fluid in the pump should be emptied to prevent the crystallization or precipitation of the medium.

5. Storage environment

During storage and use, keep the pump in a dry and ventilated environment to avoid damage to the pump due to moisture and high temperature.

3. considerations

1. Fluorine-lined pump, fluorine-lined magnetic pump and fluorine-lined centrifugal pump use pump oil when the ambient temperature is 0 ℃ ~ 10 colloid forming-filling-sealing machine grinding ℃. When the vacuum pump is running, the oil level must be kept at 1/2~3/4 of the oil window height. The oil level and oil contamination should be checked frequently (once a week is recommended).

2. Replace the fluorine-lined pump, fluorine-lined magnetic pump, fluorine-lined centrifugal pump oil and oil filter. If the oil is contaminated and blackened, emulsified or thickened, the oil should be changed in time. At the same time of oil change, the oil filter should be replaced. And clean the pump before adding new oil. Cleaning and oil change steps: stop the pump and drain the hot oil; Screw on the oil drain plug and run for 5-10 seconds to drain the oil. Inject cleaning oil (No.32 ordinary mechanical oil) to 3/4 of the height of the oil window; Run the vacuum pump for 5-10 minutes; Stop the pump and drain the oil. If the drained oil is still turbid and cannot meet the requirements, repeat steps 3 and 4 until the drained oil is transparent. Screw on the oil drain plug and run for 5-10 seconds. Drain all the oil; Just inject the specified new oil.

3. Cleaning the suction filter The suction filter should be kept clean to avoid a drop in pumping speed.

4. Replace the exhaust filter If the pump temperature rises significantly, the motor current reaches or exceeds the rated current, and the pump exhaust port has oil fume, check whether the exhaust filter is blocked. If it is blocked, it should be replaced in time. An exhaust pressure gauge can be installed at the pump filling hole to check whether the filter is blocked. The exhaust filter can be replaced when the pressure exceeds 0.6bar (gauge pressure).

5. If it is not used for a long time, it is necessary to drain the oil and clean the pump, readd the designated new oil and place it in a dry place.

6. If other users need to order maintenance spare parts, please inform the pump model and machine number can be found on the nameplate of the pump. Because some maintenance and repair work requires certain professional knowledge, equipment and special tools, please contact the manufacturer for details. Pump handling shall be oil-free. Do not hit the oil pipe, oil filter, etc.

In short, the repair and maintenance of the lining fluorine pump is very important and needs to be carried out regularly. Through reasonable repair and maintenance, it can ensure the normal operation of the lining fluorine pump, extend its service life and improve production efficiency. During use, it is also necessary to pay attention to the operation specifications to avoid damage to the pump due to misoperation. If any abnormal situation is found, it should be handled in time to avoid causing greater losses.
