The Dalan Hydraulic System reminds you to solve the problem of the internal gear pump. First, you need to understand the working principle of the internal gear pump. The Dalan Hydraulic System reminds you to solve the problem of the internal gear pump. First, you need to understand the working principle of the internal gear pump. At present, the internal gear pump commonly used has a tooth profile curve of an involute gear pump and a cycloidal gear pump (also known as a rotor pump). Their...
(1) The motor reversal will cause the steering of the motor to be opposite to the actual demand of the pump due to the wiring. Therefore, the steering of the pump should be observed first when starting normally. If the steering is reversed, any two of the terminals on the motor should be placed. What are the reasons for the lower outlet pressure of the inner ring type high viscosity pump when the wire is exchanged? (1) The motor reversal will cause the steering of the motor to be opposite to...
In recent years, many manufacturers have carried out many useful explorations and practices on how to reduce or eliminate pollutants entering the fuel tank in the design of the fuel tank structure of the hydraulic system. For example, the fully enclosed fuel tank structure currently used, except for leaving only one gas-passing vent, the fuel tanks of the hydraulic system are all closed, and all joints and joints are provided with strict sealing. The fuel filler cap is provided with a filtering...
