How to adjust the hydraulic pump

At present, the hydraulic pump has become a very important industrial production equipment, then the specific use of the hydraulic pump? What is the role of our production and living? What should we do in the event of their work? deal with? There is a valve on the hydraulic pump, there is a pressure gauge above the valve, there is a button to restore the kind of the following. Usually not when the pressure gauge no pressure, press it hard pressed when the pressure gauge, rotary valve pressure will change. How to adjust the hydraulic pump to meet the use. How to adjust the pressure gauge is the output pressure of the hydraulic pump. General hydraulic system is a relief valve. There is a variable pump. There will be one on the system. For example, the variable pressure pump is limited to 2000psi. Then the system that may be 2300psi. A limited system of work pressure. The other is used to limit system safety pressure after a problem with the first relief valve. Some systems may be equipped with more relief valve to ensure safety. Simply adjusting the pressure relief valve on the pump to regulate the pressure "makes it" possible to raise the pressure in the system to produce a larger output on the cylinder. However, there is a possibility that the system will not be over-stressed. Because you do not know how to install another relief valve in the end. Another point is to adjust the system pressure will be improved, but the branch pressure may not be increased. Because some branch pressure will be limited by the pressure relief valve. For example, the main oil pressure is 2000psi. Due to the pressure relief valve limited road pressure may only be up to 1000psi. No matter how the pressure of the main circuit increases, the branch pressure can not be raised to over 1000psi, at this time, the pressure of the valve should be adjusted. The hydraulic pump is characterized by excellent manufacturing, simple operation, can withstand large external axial force, the hydraulic pump can be connected in series with the additional pump, the hydraulic pump good spindle seal? Even in the case of high temperature low pressure shell will not happen Leakage, hydraulic pump servo valve can be connected to the function regulator and remote control system, hydraulic pump plunger set up to facilitate maintenance? Use standard tools to disassembly. Because of the special nature of products, manufacturers and researchers need to do more work and research.
