â… , due to a sudden power outage, resulting in system pressure fluctuations, the emergence of negative pressure discharge system, the bubbles dissolved in the liquid to escape the gear pump or pipeline gas. The treatment is to purge the gas. â…¡, high pressure liquid column due to a sudden power outage quickly influx, the impact of the gear pump outlet check valve plate. The treatment method is to rebuild the disposition of piping and pipe fittings of the irrational discharge system of the gear oil pump. â…¢, the outlet pipe valve closed too fast. The method is to slowly close the valve. â…£, shut down: cut off the power. The HTF is drained from the gear oil pump liquid, cleaned and the impeller should be rotated 180 degrees periodically to prevent the shaft from deforming until the oil gear pump is completely cooled. â…¤, the transmission medium to KCB-1200 gear pump cover and bearing the heat from the gear pump cover and bearing surface cooling, the bearing temperature to adapt to the shaft sealing performance temperature. Therefore, the choice of HTF gear pump installation location, to make the gear pump cover and bearing seat of the heat to facilitate diffusion, does not appear any heat storage. Under the production and sale of their own cargo oil gear pump.
