Repair and after-sales service for insufficient flow of German Fuerde mechanical diaphragm pump

German Verder mechanical diaphragm pump with insufficient flow, maintenance and after-sales service: After inserting the sleeve, the inner cavity shall be lined up to the required size, and the sleeve protruding from the end face shall be rubbed off to make it flush with the junction surface of the pump housing. At this time, the electrical circuit shall be corrected to ensure that its correct connection will shorten the working life of the reducer oil seal when the allowable temperature is exceeded, resulting in premature hardening of the sealing parts and increased wear. c) At the end of the last century and the beginning of this century, China's treasury bond was invested in the paper industry with a large proportion, and paper mills across the country scrambled to upgrade to a higher level and scale, which greatly promoted the development and production of large water ring pumps. A paper mill in the northeast of China once transformed an oversize water ring pump with an air extraction capacity of 400IIl3/min (At present, large size water ring pumps produced in China) 6 sets, with a total power of 400kW
Diaphragm pump is a commonly used pump equipment in the industrial field, and its structure and working principle make it widely used in chemical, pharmaceutical, food and other fields. However, during long-term operation, it is inevitable that some malfunctions may occur. In order to ensure the normal operation of the diaphragm pump, we need to repair it. Therefore, the following common repair techniques have been compiled for everyone. Please follow the editor to take a look together.

Maintenance Techniques for Diaphragm Pumps
1. Check for diaphragm damage:
The core component of a diaphragm pump is the diaphragm, which should be regularly inspected for damage or aging. If any damage is found, a new diaphragm should be replaced in a timely manner to ensure the sealing performance and normal operation of the pump.
2. Cleaning the pump body and pipelines:
Regularly clean the pump body and pipelines to prevent dirt, particles, or chemicals from blocking the pump's flow path. Use appropriate cleaning agents and tools to ensure that the interior of the pump is clean and free of impurities.
3. Check the valve:
Diaphragm pumps are usually equipped with inlet and outlet valves, and the valve opening and closing should be checked regularly to ensure flexibility and good sealing performance. If there are any problems, repair or replace the valve in a timely manner.
4. Adjust air pressure:
The operation of diaphragm pumps relies on compressed air, and adjusting the air pressure reasonably can ensure the normal operation of the pump. Pay attention to adjusting the air pressure according to job requirements and maintain stability.
5. Lubricating components:
The lubrication components of the diaphragm pump include bearings and piston rods. Regularly check the condition of the lubricating oil to ensure sufficient lubrication of the lubrication components and reduce wear and friction.
6. Check the seals:
The sealing components of diaphragm pumps include sealing rings and O-rings. Regularly check whether the sealing components are intact. If there is wear or aging, they should be replaced in a timely manner to ensure the sealing performance of the pump.

Perform daily maintenance and repair work to ensure the normal operation of the diaphragm pump and extend its service life. At the same time, it is also necessary to record the time and specific details of maintenance and repair, so that timely measures can be taken and resolved when problems are discovered next time.
Check the selection of hydraulic oil. If the hydraulic oil is not selected properly, it is necessary to replace it with a suitable hydraulic oil.
A walking reducer is an ideal driving device for vehicles and other mobile equipment that are either chain driven or driven
The parts and hydraulic components of the press should comply with the corresponding national standards (GB) or departmental standards (JB)

In addition, many factories in the pharmaceutical industry used to use two-stage water ring pumps with a pumping capacity of 6-12m3/min in the past, but now they are equipped with two-stage water ring pumps with a pumping capacity of 20-30m3/min, and some even reach 60m3/min. For example, a joint venture pharmaceutical factory in Sichuan purchased 10 pumps with a pumping capacity of 60m3/min in a bidding last year. Under the action of alternating stress, the material will crack and break, producing more metal particles. Firstly, it depends on the material, whether to choose rubber hoses or steel pipes, and whether to choose ordinary carbon steel or stainless steel pipes. Secondly, the inner diameter and form should be selected according to the flow rate and pressure resistance requirements. Flexible hoses are divided into wire braided and wound, with different layers corresponding to different pressure resistance. For steel pipes, the wall thickness and inner diameter should be selected. If it is a hard pipe, the wall thickness should be selected based on the inner diameter and pressure. If it is a flexible hose, only the inner diameter and pressure resistance values need to be determined, and the outer diameter does not need to be selected. The third is to choose the type of joint, whether it is a direct joint or a 45 degree or 90 degree elbow.
The length on both sides is already appropriate, and the nuts on both ends should be tightened tightly. At this point, the two ends should face each other, and the standard is that the two ends should not be too wide when the hand leaves the steel pipe. A gap of 0.5mm should be left in the middle, and the two steel pipes should be welded firmly around the circumference of the joint;

Due to excessive frictional resistance or changes in frictional resistance between relatively moving parts, the working parts may experience crawling during motion. There are various types of hydraulic components, including metric threaded connections, conical pipe threaded connections, and cylindrical pipe threaded connections. Their connection and sealing forms are different. After a period of operation of hydraulic equipment, different degrees of oil leakage problems are discovered, and the factors causing oil leakage are complex and multifaceted
If there are sand holes or cracks in the pump body, leakage will occur during pump operation. The solution is to check whether there are sand holes or cracks in the pump body. If there are, the pump body needs to be repaired or replaced. When using a diaphragm liquid pump, it is important to pay attention to daily maintenance and upkeep to avoid serious malfunctions. At the same time, if encountering unsolvable problems, professional technicians should promptly carry out maintenance and debugging.
