2 cy gear oil pump installation method: 1, 2 cy gear oil pump before installation should check the pump and motor is damaged during the transit, whether be affected with damp be affected with damp such as motor, pump the import and export of dust cover for damage and make the dirt into the pump chamber, etc. 2, 2 cy gear oil pump in the process of handling, should choose appropriate lifting position, reduce the deformation of the pump. 3, 2 cy gear oil pump base should be fixed on the basis of the strong, so as to avoid vibration influence the normal work of the pump. Import and export line 4, 2 cy gear oil pump should be cleaned up may not have hard particles and other debris. 5, pipe diameter is generally not less than the import and export of pump diameter, inlet pipe should be short, as far as possible and less detours. When necessary in the inlet install metal filter, filter the effective area should not be less than three times of pipe flow area. 6, when installation, must not use pump to take weight off line. 7, turn the coupling with the hand, the pump should be flexible rotation, can not have too tight or weight uneven phenomenon, should immediately ruled out. 2 cy gear oil pump are mainly gear, shaft, pump body, pump cover, bearing and shaft end seal, etc. Gear after nitriding treatment had a higher hardness and wear resistance. With the shaft installed inside a replaceable shaft sleeve. In all parts of the lubrication pump are using the transmission medium and automatic for when the pump work. 2 cy gear oil pump inside four bearing set floating within the pump installation, along with the work pressure automatically adjusts end clearance, so the pump pressure stability, the output flow pulsation is small, high volume efficiency. To pump from the main shaft overhang end to see, for clockwise.
