Self-priming centrifugal pump installation

The self-priming centrifugal pump is installed in the self-priming centrifugal oil pump industry represented by ethylene cracking. Although there is currently no capacity for complete equipment supply in the domestic market, in recent years, the development of centrifugal oil pump pump hub equipment has made significant progress: self-priming Centrifugal pump nozzle needle body guide surface wear. Because the mechanical impurities contained in the diesel enter the gap of the needle valve body and play an abrasive role, the needle valve will scratch the guide surface in a high-speed reciprocating motion to form a slight axial scratch. Self-priming centrifugal pump shell crack can be used to cast 508 nickel-copper welding rod welding. Welds must be tight and voids, and the flatness of the interface with the pump cover must not exceed 0.05 mm. The self-priming centrifugal pump has greatly improved the overall level of the oil pump nozzle industry in China, including technological development capabilities, advanced manufacturing capabilities, and large-scale production capacity, which has greatly promoted the quality improvement of electronically controlled common-rail pumps. The high-pressure oil pump and jack must use the specified oil working oil, and other similar hydraulic oils can also be used. For example, the oil poured into the mailbox, such as transformer oil, must be filtered. Filter once a month when used frequently, the tank should be cleaned regularly. FAW Wuxi Oil Pumps Research Institute has independently developed high-pressure direct-injection pump series of development results and won the first prize of China Machinery Industry Technology. Recently, the proportion of oil pump failures has increased in vehicles that come to be repaired and maintained. In this regard, consumers are reminded to pay special attention to the health of the original vehicle's oil pump when the vehicle is driven for more than two years. The self-suction centrifugal pump built-in type is suitable for occasions where the temperature uniformity of the liquid to be delivered is high, or the uniform cooling of the liquid at high temperature is required. When the electric heating method lacks safety or the temperature control requirements are not high, an external structure can be used.
