To address these issues, engineers conducted meticulous inspections in all aspects
Cleaning or replacing the oil suction filter element: In order to address the issue of clogging in the oil suction filter element, it is necessary to regularly clean or replace the filter element to maintain normal oil suction performance. The working temperature range of the oil seal is related to the material used: -40~120 ℃ for NBR, -30~180 ℃ for ACM, and -25~300 ℃ for FPM. Pneumatic diaphragm pumps are widely used mechanical pumps, which have the advantages of simple structure and easy use. However, in actual operation, failures are inevitable. 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.

German SERA fluorine lined pneumatic diaphragm pump with insufficient flow, repair and after-sales service
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.
The German SERA fluorine lined pneumatic diaphragm pump has insufficient flow for maintenance and after-sales, especially in highly automated situations. When hydraulic, electrical, electronic, or pneumatic are combined, the entire transmission device can achieve complex sequential actions, and remote and automated operations can be easily achieved. They found that the detachment of the transmission key may be caused by long-term operation and wear. Fourthly, it is necessary to choose hydraulic oil reasonably. When hydraulic oil flows in the pipeline, it will exhibit viscosity, and when the viscosity is too high, it will generate significant internal friction, causing the oil to heat up and increasing the resistance to oil flow. When the viscosity is too low, it is easy to cause leakage, which will reduce the system's volumetric efficiency. Therefore, it is generally recommended to choose oil with suitable viscosity and good viscosity temperature characteristics. In addition, when the oil flows in the pipeline, there are also pressure losses along the way and local pressure losses. Therefore, when designing the pipeline, try to shorten the pipeline as much as possible and reduce bends.

It should be said that before 2000, almost all manufacturers of water ring pumps in China mainly sold single pumps, and very few users ordered complete sets of equipment. However, in recent years, the proportion of complete sets of equipment in equipment bidding for technological transformation projects in the chemical and pharmaceutical industries has been increasing. Generally, it is required to equip separators, coolers (heat exchangers), replenishment pumps, valves, instruments, pipe fittings, and control devices to form a closed loop, and it is required to be connected to the OCS system of the enterprise to perform online control of liquid level, pressure, air force, etc. The clearance between the plunger and cylinder body of the plunger pump exceeds the standard for repair. The clearance between the plunger and cylinder body of the plunger pump is 0.015-0.035mm, which can cause an increase in leakage when the clearance is too large. Efficiency decreases, and even cannot work. After this situation occurs, a single cylinder or plunger can be installed. For those with a fit clearance of less than 0.120mm, chrome plating can be re applied (preferably with a chrome plating layer thickness of 0.03~0.05mm). After treatment, it is necessary to ensure that the fit clearance, roundness, and cylindricity are within the standard range.
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.
Due to load changes during operation, the system's fuel supply fluctuates, causing the working components to crawl.
In order to achieve higher volumetric efficiency, when choosing a high-pressure pump, it is important to understand the allowable limits of the internal components of the high-pressure pump
For high-pressure pumps and viscosity requirements, I will first outline the selection criteria for lubricating oil No. 1: the design type of the high-pressure pump and the required viscosity grade
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.
The pump core components may be worn out. Check the pump core components to see where the problem lies, usually due to wear or breakage of the upper and lower oil distribution discs, rotors, and stators.
The working principle of the double acting Rexroth high-pressure pump is similar to that of a single acting high-pressure pump, with the only difference being that the stator surface is composed of eight parts: two long radius arcs, two short radius arcs, and four transition curves, and the stator and rotor are concentric
Serious air suction); B. The hydraulic oil is severely contaminated, forming large chemical particles, the filter screen is broken, and foreign objects enter the pump body, causing wear and tear
The German SERA fluorine lined pneumatic diaphragm pump has insufficient flow rate for maintenance and after-sales service. Each of these high-pressure pump designs is deployed as a target performance task, and only correct maintenance can ensure the normal operation of the hydraulic motor and extend its service life. In addition, hydraulic motor maintenance also needs to pay attention to some details. Firstly, safety should be taken into account during the maintenance process to ensure the personal safety of personnel. Secondly, the correct tools and equipment need to be used during the maintenance process to ensure the accuracy and reliability of the repair. After the repair is completed, testing and debugging are required to ensure the normal operation of the hydraulic motor.
What is the transmission method of the ULVAC pump maintenance pump? The two rotors of the pump are synchronized through a pair of high-precision gears. The active shaft is connected to the motor through a coupling. There are two main ways to install the transmission structure: one is to place the motor and gear on the same side of the rotor as shown in the figure. The driven rotor is directly transmitted from the motor end gear to the drive shaft, so that the deformation of the active rotor shaft is small. What is the transmission mode of the ULVAC pump maintenance pump? The gap between the two rotors will not be changed due to the large deformation of the active shaft, so that the gap between the rotors is uniform during the working process. The major drawback of this transmission method is that: a. there are three bearings on the drive shaft, which increases the difficulty of pump processing and assembly, and the disassembly and adjustment of gears are also inconvenient; b. The overall structure is uneven, with the center of gravity of the pump leaning towards the side of the motor and gearbox.
The application advantages of Edward Roots pump maintenance for water ring pumps are that the operating pressure of the pump should meet the maximum vacuum and operating pressure requirements of the vacuum equipment
High pressure pumps and other moving parts suddenly switch from high speed to low speed. Due to the action of inertia force, the moving parts need to move forward for a certain distance before moving at the set working speed at low speed. This phenomenon is called forward thrust. So why does the throttle speed control valve of the high pressure pump have forward thrust? How to eliminate and solve it? The daily editor will explain to you the analysis and troubleshooting methods for the front flushing of the throttle speed control valve of the high-pressure pump. The following are the reasons: the flow rate of the high-pressure pump changes too quickly, and the sudden change in flow rate causes the output pressure of the pump to suddenly rise, resulting in impact
