YCB arc gear pump should pay attention to matters Circular gear pump gear, shaft, bearing sleeve, pump body, pump cover, shaft seal and other components. The pump is a marine pump with smooth operation, low noise, long life, high efficiency, this series of pumps using mechanical seal, according to user requirements can also be used packing seal. Matters needing attention when using YCB series arc gear pump: 1, disassembly and assembly, according to the total assembly drawings. 2, out of the pipeline should not be sharp turn to prevent clogging. Third, master YCB series arc gear pump operation cycle replacement bearing, to prevent accidents. Fourth, stop the pump when the water rinse release net, to prevent winter frost crack. Fifth, should be adjusted in the YCB series arc gear pump technology used in order to achieve economic and durable. Sixth, in order to prevent the top of the bad frame, when installed in the motor, to measure the pump shaft in advance. Arc gear pump wear too much results arc gear pump internal parts wear pump internal parts wear and tear can cause internal leakage. Among them, the leakage area between the floating bushing and the gear end face is large, which is the main part of the internal leakage. This part of leakage accounted for 50% of the total internal leakage of about 70%. The wear and tear of the internal leakage gear pump volumetric efficiency decline, arc gear pump output power is much lower than the input power. The loss of all the heat into the heat, it will cause the pump overheating. If the combination of flat compression, due to work floating sleeve will be a small amount of exercise caused by wear and tear, resulting in slow or can not enhance the farm tools, such a floating sleeve must be replaced or repaired. YCB arc gear pump is a kind of positive displacement pump, which consists of two gears. The pump body and the front and rear covers form two closed spaces. When the gear rotates, the volume of the space on the side where the gear is disengaged increases from small to large and forms a vacuum. When the liquid is sucked in, the volume of the space on the meshing side of the gear decreases from large to small, Squeeze into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of two gears. The pressure at the outlet of the gear pump depends entirely on the resistance of the pump. YCB arc gear pump operation and maintenance (1) before starting to check all pipe flanges, joints tightness. (2) Disc drive coupling, no friction and collision sound. (3) The first start should be injected into the pump liquid. (4) should be fully open before inhalation and discharge of the valve in the pipeline, closed valve is strictly prohibited to start. (5) After verifying the direction of motor rotation, start the motor.
