Mixer Lainuo A4VTG71HW/32r-NLD10F001S Hydraulic Pump

① When starting the hydraulic pump, it should be jogged several times. After the oil flow direction and sound are normal, it should be operated at low pressure for 5-10 minutes before being put into normal operation. Before starting the plunger pump, clean working oil must be filled into the pump through the oil drain port on the casing.
  ② The viscosity of the oil changes with the influence of temperature, and the viscosity decreases with the increase of oil temperature, so the oil temperature is required to be kept below 60 ℃. In order to make the hydraulic pump work stably at different operating temperatures, the selected oil fluid should have the oil temperature characteristics that the viscosity is less affected by temperature changes, as well as better chemical stability, foam resistance, etc. It is recommended to use L-HM32 or L-HM46 (GB11118.1-94) anti wear hydraulic oil.
  ③ The oil must be clean and free from mechanical impurities and corrosive substances. Hydraulic systems without filtration devices on the oil suction pipeline must pass through a filter truck (with a filtration accuracy of less than 25 μ m) Fill the fuel tank with oil.
  ④ The pressure and speed of a hydraulic pump refer to the allowable peak value during a short period of use, and long-term use should be avoided, otherwise it will affect the service life of the hydraulic pump.
  ⑤ The normal operating oil temperature of hydraulic pumps is 15-65 ℃, and the temperature on the pump casing is generally 10-20 ℃ higher than the oil temperature at the pump inlet in the oil tank. When the oil temperature in the oil tank reaches 65 ℃, the temperature on the pump casing does not exceed 75-85 ℃.
