Structural characteristics of the pump body of the hot oil pump

The pump body structure of the hot oil pump can be assembled according to the structural form in actual production and work according to the working principle during use. The pump shaft of the hot oil pump is equipped with a packing box at the front end, which has good sealing performance. At the same time, a mechanical sealing device is installed in the bearing seat, so a large amount of leakage is impossible to occur, and a small amount of leakage can be discharged and received through the leakage pipe mouth. It is normal to have a small amount of leakage at the beginning of operation, but the leakage will decrease or stop after the sealing surface is closed over time. There are two ball bearings installed in the bearing seat of the hot oil pump. One ball bearing on the impeller side of the heat transfer oil pump is lubricated with the conveyed heat transfer oil, and the other ball bearing on the coupling side is lubricated with high-temperature grease. After running for 3000 hours, each ball bearing is removed and cleaned with diesel, and the contact surface is checked for damage. If damaged, a new bearing is replaced. Do not use the gate valve on the input pipe to adjust the flow rate to avoid cavitation.
