  1. It is difficult for the hydraulic vane pump to suck oil. Check and clean the oil filter and check the oil viscosity, and change the oil in time.
  
  2. The pump cover screw is loose or the bearing is damaged. Check for tighter, more slippery parts.
  
  3. The surface of the stator has flaws. When the blades come into contact with it, a beating impact noise occurs. The surface of the stator needs to be polished.
  
  4. The oil level of the fuel tank is too low, the oil seal on the suction side of the hydraulic pump, the suction pipe section, and the oil seal on the main shaft of the hydraulic pump are defective, and air enters. It is necessary to check whether there are leaks in the relevant sealing parts and seal them tightly to ensure that there is enough oil and smooth suction.
  
  5. The motor speed is too high. The motor needs...    less
