UK BLAGDON plunger diaphragm pump has abnormal noise maintenance tutorial

British BLAGDON plunger diaphragm pump has abnormal noise maintenance tutorial: From the above analysis, it can be seen that hydraulic medium pollution (particle type pollution) is the main culprit of hydraulic component wear, which leads to the production of more metal particles, making hydraulic medium pollution more serious and forming a vicious cycle. Each pump type must be considered on a case by case basis when selecting lubricants
Firstly, fault diagnosis is required before repairing the hydraulic motor. During use, only in cases of temporary overload or within the scope specified in the product manual, are plunger pumps allowed to be selected
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.
The sudden change in speed causes a sudden change in pressure, resulting in an impact. For the outlet throttling system, the pressure in the rear chamber suddenly increases, and for the inlet throttling system, the pressure in the front chamber suddenly drops, even becoming negative pressure. Fault diagnosis is a step in maintenance, which can help us accurately identify the problem and take the correct maintenance measures, especially with the characteristic of isothermal compression, which easily sucks and compresses flammable and explosive gases

The rated pressure of the pump should be determined based on the working pressure of the hydraulic cylinder. In the sample of plunger pump products, it is indicated that the rated pressure and pressure value of the pump will shorten the working life of the reducer oil seal when exceeding the allowable temperature, causing premature hardening of the sealing components and increasing wear. The main drive shaft gasket is mainly used to adjust the preload of the transmission bearing, ensuring the clearance between the joint surfaces of the regulator, distribution plate, copper cylinder body, center rod, ball head bearing, etc.
The wear of high-pressure pumps is mainly in the tooth thickness area, while the wear on the end face and tooth tip is relatively light. In the thick tooth area, there is unilateral wear, so it can be flipped 180 degrees for use. When the end face is worn, the end face can be ground flat, and the joint surface of the lubricating oil pump housing can be ground at the same time to ensure that the gap between the end face and the pump cover is within the standard range. Air forms bubbles in the oil, and if the pressure of the hydraulic support rapidly changes between high and low pressure in a very short period of time during operation, the bubbles will generate high temperature on the high pressure side and burst on the low pressure side. If there are pits and damages on the surface of the hydraulic system components, the hydraulic oil will rush towards the component surface at high speed, accelerating surface wear and causing leakage. This corrosion caused by cavitation is called cavitation

Dustproof: To prevent pollutants, dust, and moisture from entering the sealed chamber from the air side, it is recommended to use oil seals with dust-proof devices for the reducer bearings. If pollutants invade severely, it is recommended to use two oil seals installed in series, one in front and one behind. With the development of modern industry, hydraulic transmission has been increasingly applied. Hydraulic transmission is a new technology compared to mechanical transmission. Early hydraulic transmission used water as the transmission medium, while modern hydraulic transmission was driven by the booming petroleum industry. Especially in highly automated environments, when hydraulic, electrical, electronic, or pneumatic systems are combined, the entire transmission system can achieve complex sequential actions and facilitate remote and automated operations
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.
