RYB internal gear pump connection precautions 1 RYB internal gear pump can be installed with bearings or flanges. The pump and prime mover should use a common foundation support. The flange and foundation should be rigid enough. Botaibang pays special attention: the plunger pump with flow rate greater than (or equal to) 160L/min should not be installed on the fuel tank.
2 RYB internal gear pump and the output shaft of the prime mover should be connected by elastic coupling. It is strictly forbidden to install the pulley or gear to drive the internal gear pump on the pump shaft. If it is necessary to connect the pulley or gear to the pump, Add a pair of bearings to install the pulley or gear. The coaxiality error between the bearing and the pump shaft should be no more than Φ0.05mm.
3 The oil suction pipe should be as short, straight, large and thick as possible. The oil suction pipe generally needs to set a coarse filter with a nominal flow rate not less than 2 times the pump flow rate (the filtration precision is generally 80-180μm). The drain pipe of the RYB internal gear pump should be directly connected to the fuel tank, and the back pressure of the oil return should be no more than 0.05MPa. The oil suction pipe and oil return pipe of the oil pump must be below the oil level of the oil tank of 200mm or less. Special attention should be paid to the installation of the oil filter on the suction pipe of the plunger pump. The diameter of the stop valve on the suction pipe should be larger than the diameter of the suction pipe. The length of the suction pipe L 4 RYB should be the inlet and outlet of the gear pump. The installation is firm and the sealing device should be reliable. Otherwise, the phenomenon of inhaling air or oil leakage will occur, which will affect the performance of the RYB internal gear pump.
5 RYB internal gear pump self-suction height does not exceed 500mm (or imported vacuum does not exceed 0.03MPa), if the oil supply pump is used, the oil supply pressure should not exceed 0.5MPa, when the oil supply pressure exceeds 0.5MPa, it should be used instead. Pressure seal. For the plunger pump, the self-priming method should be adopted as much as possible.
6 Before installing the RYB internal gear pump, check whether the depth of the mounting hole is greater than the shaft elongation of the pump to prevent the top shaft from being generated, otherwise the pump will be burnt.
