In order to achieve higher volumetric efficiency, when choosing a high-pressure pump, it is necessary to understand the allowable limits of the internal components of the high-pressure pump. At the same time, they have also adjusted the overall flow regulation of the variable pump to ensure its normal operation. They can generate much higher working pressures - up to 6000 pounds. Pneumatic diaphragm pumps are widely used mechanical pumps, which have the advantages of simple structure and easy use, but they are inevitably prone to failures in actual operation. This article will provide you with a detailed introduction to the common causes of faults and their maintenance methods based on the experience of Yongqiu Pump Industry. It should be noted that during maintenance, the gas and power sources should be removed first, and personnel safety should be ensured.

1. Pump head leakage is one of the common faults of pneumatic diaphragm pumps, which may be caused by damage or aging of the pneumatic drive membrane, wear or dirt on the sealing surface of the pump head, and poor sealing of the inlet or outlet valves of the pump head.
2. Pump body leakage is another common fault, which may be caused by wear or dirt on the sealing surface of the pump body, damaged or aged diaphragm, and poor sealing of the inlet or outlet valve of the pump head.
3. The inability of pneumatic valves to control the start and stop of pumps is another common fault of pneumatic diaphragm pumps, which may be caused by poor contact of the pneumatic valve control circuit, internal component failures of the pneumatic valve, insufficient or excessive air pressure.
4. There may be abnormal noise or vibration in the pump body, which could be caused by improper or damaged diaphragm installation, impurities or dirt inside the pump body, loose connection between the pump body and the base, or uneven base.
If the pressure imbalance maintenance and after-sales service of the Italian IP Imoviri mechanical diaphragm pump occurs during the initial installation of the pump, it should be caused by the leakage of the system's control valve or the high oil temperature. If the above problems occur after a period of use, it is necessary to check whether the upper and lower oil distribution discs are worn (very flat wear). If the gap between the upper and lower oil distribution discs is too large and the oil temperature is too high (unable to form a self sealing oil film), the control valve leakage will cause the system to drop pressure. 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 more metal particles being produced, making the hydraulic medium pollution more serious and forming a vicious cycle. When the oil discharge volume of the axial piston pump is insufficient, the actuator action is slow.

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, the rated pressure and pressure value of the pump are indicated
Repair the valve core to ensure its normal operation. With the increase of usage time, high-pressure pumps may experience faults such as insufficient or even no oil pumping, mainly due to excessive wear and tear on relevant parts. The editor of Changzhou Silewei Technology Co., Ltd. learned that the wear parts of high-pressure pumps mainly include the active shaft and liner, passive center hole and shaft pin, pump housing inner cavity, end face and pump cover. When the main technical indicators of the lubricating oil pump do not meet the requirements after wear and tear, it should be disassembled and decomposed to identify the wear area and degree, and corresponding measures should be taken to repair it.
We can adopt corresponding maintenance methods to address common causes of malfunctions. When repairing or replacing components, it is necessary to select parts that meet the requirements and ensure that their quality and specifications are the same as the original. When disassembling, cleaning, or replacing components, the correct steps should be followed to avoid affecting other components.
The types of water-based fluids are not common. These fluids are usually needed where there is a high probability of fire. They are more expensive than oil, but cheaper than synthetic materials. Although they provide good fire protection, they lack the ability to protect against wear and tear. (1) Reasonably select hydraulic actuators based on the motion form of the working components; (2) List various basic circuits that may be implemented based on the performance requirements and action sequence of the working components
Reverse connection of motor electrical circuit: If the electrical circuit of the motor is reversed, it will also affect the normal operation of the high-voltage pump
Diaphragm pumps may experience common malfunctions during long-term operation, such as pump leakage, pump failure or difficulty in starting, high pump operating noise, and unstable pump flow. To address these issues, we can take appropriate maintenance and replacement measures by checking the condition of components such as the diaphragm, pump body, and motor to ensure the normal operation and functioning of the diaphragm pump. At the same time, in daily use, paying attention to regular inspection and maintenance of diaphragm pumps, strengthening maintenance, is also an important measure to prevent failures. Through proper use and maintenance, diaphragm pumps can continuously and stably perform their functions of liquid transportation and pumping.
Many industries in the chemical and pharmaceutical industries require a large amount of exhaust gas for vacuum distillation, concentration, dehydration, drying, and power plant exhaust removal under high vacuum conditions. Single stage water ring pumps have relatively weak exhaust capacity in this range, while two-stage water ring pumps and two-stage water ring pumps with a first stage atmospheric injector have a large intake capacity in this range. Before 2000, the demand for two-stage pumps was mostly below 15m3/min, but now it reaches 40-50m3/min. In addition, it should be pointed out that when a single-stage water ring pump is equipped with a first stage atmospheric injector, if the design is reasonable, there is still a large amount of pumping volume at a suction pressure of 4-5 kPa, which greatly expands the scope of use of single-stage water ring pumps. For example, a certain aircraft research institute in China has used multiple pumps of this type. In summary, it can be seen that water ring pumps and water ring compressors, as basic equipment for obtaining rough and low vacuum, have been widely used in various industries. It can also be said that the rapid development of various industries in the national economy has promoted the development and production of water ring pumps and water ring compressors.
It will reduce the density of the ring and enrich more micropores, low melting point impurities, gases, and non-metallic inclusions inside It, like strip carbides, plays a role in dividing the continuity of the matrix, causing component segregation and matrix brittleness, greatly reducing the comprehensive mechanical properties of the ring. In addition, it increases friction resistance and notch sensitivity during grinding, promoting high concentration of grinding stress and easily inducing grinding cracks. Let me take you to understand the maintenance knowledge of high-pressure pumps
Due to the fact that the working process of a high-pressure pump involves continuous indirect work or periodic back and forth movements, there is a device called an accumulator in the high-pressure pump system

The reasons for the wear of the upper and lower oil distribution discs and rotors are as follows: A. Insufficient oil suction of the high-pressure pump (oil pump suction height too high: generally not exceeding 500mm, not filling the pump body with hydraulic oil when starting for the first time, inlet pipe)
When piping the system, it is necessary to eliminate pipeline stress. First, install a combination sealing gasket on the pipe joint body, and then tighten it on the hydraulic component or oil circuit block. Do not place the O-ring this time;
Replace the appropriate hydraulic oil: According to the viscosity requirements of the hydraulic oil, replace the appropriate hydraulic oil to ensure the normal operation of the high-pressure pump
It is reported that the transmission key of the high-pressure pump fell off during operation, causing the equipment to malfunction. The pump needs to be regularly replaced with diesel engine oil. Diesel engine oil must be replaced regularly: the new pump should be replaced first after 50 hours of operation, after 200 hours of operation for the second time, and after 500 hours of operation for the third time. Diesel engine oil is not the same type of oil, and the type of diesel engine oil replaced for each pump type is different. If you are unsure, please feel free to contact me privately! Regular maintenance also extends its service life!
Under the same volume, hydraulic devices can generate greater power than electrical devices. At the same power, hydraulic devices have small volume and mass, meaning they have high power density and compact structure. The type of each pump must be considered as the selection of lubricant on a case by case basis
When the direction of the oil port is not suitable and inexperienced customers adjust it themselves, if the pump core is not inserted into the small hole (caused by pulling it out during rotation), the space of the oil pump suction port will shrink, and the oil suction will be obstructed and not smooth. This is manifested as excessive noise, pressure swing, long-term use will cause the oil temperature to rise too quickly, and the curve inside the stator will be impacted into a ripple shape, which will shorten the service life
