Zhengzhou Batte melt pump manufacturer specializes in providing high standard and new generation melt pump equipment for thousands of domestic and foreign customers; Bate melt pump manufacturer provides special melt pump equipment including PVC melt pump, high temperature and high pressure melt pump, rubber melt pump, etc. The following specific analysis causes the flow pulsation of the melt gear pump.
The most non-uniform instantaneous flow of the melt gear pump will produce flow pulsation, if the output flow of the melt pump is directly input into the actuator, the speed of the actuator will be invariable; if the outlet of the melt pump is parallel with a flow-nourishing valve, such as the application of the melt pump in the throttling speed control loop composed of a flow-nourishing valve, a throttling valve and a hydraulic cylinder In the road, the pulsating flow will produce pressure fluctuation or misoperation of pressure relay when it flows through the flow control valve. Another reason is that the pressure fluctuation of melt may also cause vibration and noise of hydraulic system; in severe cases, if the fluctuation frequency is the same as the natural frequency of hydraulic system, it will cause resonance of hydraulic system, which is harmful to the use of transmission shaft and bearing of melt pump, as well as the use of pipe joints and seals. Influence. All these will destroy the performance of the hydraulic system and shorten the service life of the hydraulic components in the system, thus affecting the operation of the hydraulic system.
