Wagner WAGNE High Pressure Diaphragm Pump Noise Abnormal Maintenance Service Center in Germany:
It is possible to store the excess pressure oil output from the high-pressure pump well during work. After a long time, I believe everyone has encountered similar situations. Hydraulic equipment pipelines and equipment operate for a period of time, and different degrees of oil leakage problems are found. The factors of oil leakage are complex and multifaceted. These roles range from heat transfer media, power transfer media, and lubricating media. Generally, the vacuum degree of the pump should be half to one order of magnitude higher than that of the vacuum equipment
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.
Coarse and fine filters should be configured in the system as needed, and the filters should be regularly inspected, cleaned, and replaced. The adjustment of pressure components generally starts with adjusting the system pressure valve - relief valve, starting from zero pressure and gradually increasing it to the specified pressure value; Then adjust the pressure valves of each circuit in sequence. The adjustment pressure of the safety relief valve of the high-pressure pump in the main oil circuit is generally greater than 10% -25% of the required working pressure of the actuator. The pressure valve of the high-pressure pump for sports generally adjusts the pressure by 10% to 20% higher than the required pressure. If unloading pressure is used to supply oil and lubrication oil, the pressure should be maintained within the range of 0.3-0.6MPA. The adjustment pressure of the pressure relay should generally be 0.3-0.5MPA lower than the oil supply pressure.
A high-pressure pump with a sound pressure level exceeding 90dB (A) produces very loud noise, and around 60dB (A) is considered relatively quiet. In addition, at the outlet of the high-pressure pump, it can be used to continuously absorb the pulsating pressure generated during operation, so that the pump can operate and work better, increasing efficiency
① Gas pollution: Under atmospheric pressure, about 10% of air can be dissolved in hydraulic oil. Under high pressure in hydraulic systems, more air or gas will dissolve in the oil. After lining the inner cavity to the required size and grinding off the sleeve protruding from the end face, the oil level will be checked to ensure that the system has sufficient oil volume.
Liquid resistance is a phenomenon in which energy is lost due to the viscous frictional force of a liquid flowing through a pipeline, resulting in a decrease in pressure. In a broad sense, hydraulic resistance refers to hydraulic valve ports and similar structures such as thin-walled small holes, short holes, slender holes, gaps, etc. that can locally change the flow area of the liquid flow to cause pressure loss (resistance characteristics) or distribute and adjust the flow rate (control characteristics) under a certain pressure difference. Liquid resistance is divided into longitudinal resistance and local resistance. All types of liquid resistance should satisfy the flow pressure equation. From this broad concept, it can be seen that the essential functions of liquid resistance include two aspects: pressure reduction is its resistance characteristic (the pressure before and after the liquid resistance can vary greatly), and flow restriction is its control characteristic (changing the size of the liquid resistance can change the flow rate passing through). Starting from the basic functions of liquid resistance, the following types are currently widely used. The typical viscosity range of a piston pump is 10 to 160 CST operating temperature

The hydraulic device works relatively smoothly. Due to its low mass and inertia, as well as fast response, hydraulic devices are easy to start, brake, and frequently change direction. ③ Water pollution: Due to factors such as humid working environment, water may enter the hydraulic system, react with hydraulic oil, form acidic substances and sludge, reduce the lubrication performance of hydraulic oil, accelerate component wear, and cause the valve stem of the control valve to bond, making it difficult to operate the control valve, scratching the seals, and causing leakage
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.
