WhiteKnight Four Cylinder Diaphragm Pump Leakage Repair Service Center

White Knight Four Cylinder Diaphragm Pump Leakage Repair Service Center: Characteristics of the Secondary Quenched White Layer Structure: Due to the fact that the white layer is a multi-phase highly dispersed structure coexisting with austenite, martensite, and carbides There is a coherent pseudo equilibrium system and a difference in lattice constants between austenite and martensite. Therefore, when martensite is formed, the lattice of secondary austenite undergoes strong darkening, which leads to the hardness of the white layer structure. Therefore, we should strengthen our learning and practice of hydraulic motor maintenance, improve maintenance skills, and provide pollution generated during the operation of hydraulic systems, such as carbonization and deterioration of hydraulic media, for the normal operation of mechanical equipment; The wear and tear of hydraulic components will not be further elaborated. Fault diagnosis is a step in maintenance, which can help us accurately identify the problem and take the correct repair measures
In daily use, some users of diaphragm pumps may encounter some common problems. How to repair problems after they occur? Below we will briefly introduce the common problems and maintenance methods of diaphragm pumps, hoping to be helpful to everyone.

There are generally several situations, one of which is a decrease in air pressure. First, take a look at the pressure on the intake pressure gauge. The pressure value is abnormal. Then check the open position of the air source valve. If using a solenoid valve to open and close the air source, please check if the plastic valve of the solenoid valve is damaged. The second reason is that the muffler is blocked, preventing the air from being quickly expelled, resulting in a decrease in exhaust speed. Thirdly, there is too much water or impurities in the compressed air. After entering the air valve of the diaphragm pump, block the air inlet or block the air valve core. Fourthly, due to the continuous impact of the valve core, the upper and lower end caps of the air distribution valve are damaged and leak.
Before assembling the repaired plunger pump, it is necessary to select suitable center rod gaskets and main drive shaft gaskets for adjusting the selection of gaskets. The thickness of the center rod gasket must be sufficient to prevent axial movement during start-up. In addition, a suitable pre tension force is generated by the combined action of the disc spring and the adjusting gasket to automatically compensate for the clearance caused by the wear of the distribution plate, ensuring reliable end face sealing between the cylinder block and the distribution plate. Fault diagnosis is a step in maintenance, which can help us accurately identify the problem and take the correct repair measures
So how should we solve the problem of oil leakage in the equipment pipeline connection above the high-pressure pump? Today, the Japanese editor will talk to you about the solution to oil leakage in the equipment pipeline connection on the high-pressure pump, as follows
The noise of high-pressure pumps is relatively high, with a large flow pulsation rate, while the noise of internally meshed high-pressure pumps is relatively low, with a small flow pulsation rate; The noise of high-pressure pumps, screw pumps, and plunger pumps is relatively low, and the noise of double acting high-pressure pumps is lower than that of single acting high-pressure pumps. Repair of working surfaces: If the working surface of the pump cover has less wear, manual grinding can be used to eliminate wear marks, that is, placing a small amount of valve sand on the platform or thick glass plate, and then grinding the pump cover on top until the wear marks are eliminated and the working surface is flat. When the wear depth of the working surface of the pump cover exceeds 0.1 millimeters, the method of first turning and then grinding should be adopted for repair.
Therefore, in order to better adapt to the development of various industries, the following preliminary opinions are proposed for the research and development of this pump. (1) By using feasible design and high-performance sealing components, the reliability of the water ring pump and water ring compressor during the uniform and trouble free operation period (MTBF) of the entire machine can be improved. Compared with other equipment for obtaining rough and low vacuum, the uniform and trouble free operation period can reach more than 10000 hours. But with the improvement of technology in various industries and the increasing demand for the reliability of the entire vacuum system, the reliability requirements for it have also correspondingly increased.

Corresponding maintenance methods and steps are provided for different problems, including adjusting or replacing pressure valves, inspecting oil replenishment valves and feeding systems, inspecting or replacing feed and discharge valves, adjusting speed, replacing gaskets and seals, etc. At the same time, repair suggestions are provided for other issues, such as cleaning the air inlet filter, inspecting and replacing the membrane, and dealing with icing problems. Through these maintenance methods and steps, common faults of pneumatic diaphragm pumps can be effectively solved and their normal operation can be restored.
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 found. The factors causing oil leakage are complex and multifaceted. Research on the working steam and its dryness: low steam pressure and pressure fluctuation have a significant impact on the pump's ability, so the steam pressure should not be lower than the required working pressure. However, the pump structure design used has been finalized, and excessive improvement in steam pressure will not add pumping volume and vacuum degree. Additionally, it is important to ensure that the steam pressure supplied by the boiler is stable. It is recommended to use a boiler specifically to supply working steam to the steam injection pump, so that the steam pressure does not fluctuate and the pump function is stable.
WhiteKnight four cylinder diaphragm pump leakage repair service center maintenance process:
1. Regular inspection and cleaning: Regularly inspect various components of the diaphragm pump, such as diaphragm, ball valve, connecting rod, etc., to check for wear, aging, or damage. After each use, clean the pump body and its inlet and outlet pipelines to prevent material residue and pipe diameter reduction
2. Lubrication maintenance: Regularly add an appropriate amount of lubricating oil to the bearing body to ensure that the oil level is at the centerline of the oil gauge, and replace or replenish the lubricating oil in a timely manner. For pneumatic diaphragm pumps, ensure that the air source is clean and dry, and regularly replace the lubricating oil
3. Sealing performance inspection: Regularly check the sealing performance of the diaphragm pump, including components such as the diaphragm and sealing ring, to ensure that they are intact and undamaged. If there is wear or aging, it should be replaced in a timely manner to prevent air leakage or a decrease in pump capacity
4. Temperature and pressure monitoring: Monitor the temperature of the pump body and motor to prevent overheating. At the same time, check the inlet and outlet pressure and flow rate of the pump to ensure that they are within the normal operating range. When there are significant fluctuations in pressure or flow rate, it is necessary to promptly investigate and resolve them
It should be said that before 2000, almost all manufacturers of water ring pumps in China mainly sold single pumps, with very few customers ordering 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 be equipped with separators, coolers (heat exchangers), replenishment pumps, valves, instruments, pipe fittings, and control devices, forming a closed cycle, and requiring cooperation with the enterprise's OCS The system is connected to control the liquid level, pressure, and air force online. Due to the use of expired hydraulic oil or regenerated oil, the surface of the pump core parts appears black or sticky. Impurities, toxins, and corrosiveness in the oil can cause early damage to the oil pump. The lack of lubrication and wear resistance in the regenerated expired oil can also greatly shorten the life of the pump core, and even cause it to stick to the pump core and cannot move.
Double acting high-pressure pumps have a longer lifespan, while single acting high-pressure pumps, plunger pumps, high-pressure pumps, and screw pumps have a shorter lifespan. In terms of price, plunger pumps are more expensive than high-pressure pumps, while screw pumps are more expensive. However, in terms of reliability, screw pumps are more stable, followed by plunger pumps, high-pressure pumps, and high-pressure pumps.
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
