Variable oil pump expensive and sensitive. Variable pump maintenance, in the first manipulation and routine maintenance should note the following: the pump oiling: Before 啔 oil pump, fuel injection pump from the fuel inlet to the inside until it filled up. If you start the pump variable pump before oiling, may be due to insufficient lubrication failure. Pump can not be reversed: Note electrical wiring, reversing might damage the pump. Hydraulic Oil Selection: Selection 20-200Cstnian hydraulic oil viscosity hydraulic oil, recommended 30-50cST quality hydraulic oil viscosity. When the oil temperature is below 5 degrees, to deal with the hydraulic oil for heating. Cleanliness of hydraulic oil should be kept in NAS10 below. Variable pump repair phone should be cleaned every three months back the oil filter cartridge. Variable pump care to keep the oil flow and clean. Oil level in the oil holding ruler bits or more: When the oil level is too low, the hydraulic oil is contained in the air is not sufficiently released, so that the pumps produce much noise and damage. .
