Qidong lubrication oil station factory direct light oil lubrication station, lubrication system. GXYZ Series B high (low) and tube oil pressure lubrication oil station for the integral tank, two low-pressure pump, a high-pressure pump, two sets of binoculars network chip filter, back to the oil Magnetic mesh filter device, cooler, a variety of control valves, piping, and electrical contact pressure gauge, platinum thermal resistors and other components. 
 The working principle is basically and A Series; B Series low-pressure oil through the filter and cooling when the outside for part of the low-pressure oil through the bypass and then through the suction port of a binocular filter before entering the high-pressure pump in order to improve the high-pressure the cleanliness level of oil; but it should be noted that when the actual pressure of the low pressure fuel supply is small (eg less than 0.2MPa), because a filter is also the loss of pressure difference (also gradually increased over time) in order to ensure the high pressure pump smoothly inhalation, the intake should always be to ensure positive pressure (when the differential pressure reaches the maximum after the filter before switching must also meet this requirement); very different, the most important characteristics (structural characteristics) in addition to traffic and the Series A high-pressure pump another filter before suction.
