Representative works of potow heat pump is the KCG and RY high temperature heat conduction oil pump, gear pump, they have good resistance to high temperature performance, botou susquehanna pump co., LTD., specializing in the production of all kinds of high temperature, and heat conduction oil pump gear pump products, high temperature on both sides of the pump body and cover gear pump for direct contact with the hard seal, if the flatness of contact surface can not meet the specified requirements, The pump is easy to inhale air at work; Similarly, the pump end cover and gland is also direct contact, air is also easy to invade; If the gland is plastic products, due to its damage or deformation due to temperature changes, it will also make the seal lax and enter the air. The method to eliminate this fault is: when the flatness of the pump body or pump cover does not reach the specified requirements, you can use gold steel sand to grind back and forth according to the zigzagging route on the flat plate, and can also grind on the plane grinder, so that the flatness is not more than 5μm, and need to ensure that the plane and hole perpendicularity requirements; For leakage of oil pump cover and gland, adhesive such as epoxy resin can be used for sealing.
High temperature oil pump is an ideal heat conduction oil circulation pump or heat carrier pump, is the ideal supporting pump for heat exchange equipment. There are many ways to cool the hot oil pump. First of all, we should analyze the sealing structure of the hot oil pump, and adopt different cooling methods according to different sealing structures. The high temperature oil pump adopts the form of packing seal and mechanical seal. The packing seal uses high temperature resistant packing, which has good thermal adaptability. The mechanical seal uses hard alloy material with high mechanical strength and good wear resistance, which ensures the sealing performance of the oil pump at high temperature.
