Pump noise, vibration, causing the pipe, tank resonance 1. pump into and out of the oil port with a hose connection 2. Do not install the pump in the fuel tank, the motor and the pump should be mounted on the base alone Dingxi pump motor, hydraulic pump and tank separately 3. increase, reducing the number of revolutions of the motor and volume increases will result in a partial vacuum, so that the oil Dissolved gas separation Ankang pump motor, cavitation, which will make a strong noise gear pumps, gear pumps, which is the phenomenon of trapped oil. Way to eliminate trapped oil, usually on both sides of the two end caps milling gear pump unloading slot. ③ radial unbalanced force pump gear pump motor acting on the outer circle of the gear is not equal to the pressure in the high pressure chamber and the suction chamber of the gear tooth profile and cylindrical surfaces bear work pressure and suction chamber pressure,
