Self-priming centrifugal pump adopts axial liquid return pump body structure, the pump body is composed of suction chamber, liquid storage chamber, vortex chamber, liquid return hole, gas-liquid separation chamber and so on. The bearings of the pump are single row centripetal ball bearings. A cooling chamber is arranged at the bottom of the bearing body of the pump, and a sealing ring is provided in the high and low pressure sections of the pump. The shaft end is mechanically sealed.
The self-priming centrifugal water pump is equipped with a bottom valve at the bottom of the suction line, which requires more water to cover the entire suction line before starting. The bottom valve often fails because it is clamped into debris or closed loosely. Eliminating these failures sometimes takes a lot of labor, especially in winter. Self-priming centrifugal pump suction inlet is generally higher than the impeller suction inlet, as long as the pump body water can start, without the above defects. Labor this activity of drainage and irrigation, mobile work, frequent start and water injection problems of the occasion is very convenient to use self-priming pump, agriculture, building construction, oil tank truck unloading, oil depot, fire and shipbuilding and many other places use self-priming pump.
2. Make the type and performance of the selected pump conform to the flow of the device. Head, pressure, temperature. Requirements for process parameters such as cavitation flow rate and suction range.
3. The cost of equipment should be comprehensively considered economically. The total cost of maintenance and management is the lowest.
4. Self-priming centrifugal pump with high speed. Small size and light weight. High efficiency. Large flow. Simple structure. No pulsation in infusion. Stable performance, easy operation and easy maintenance. Self-priming centrifugal pump is used to transport gasoline, kerosene, diesel, aviation kerosene and other petroleum products. Medium temperature of -20℃ ~ +80℃, is an excellent Marine loading and unloading oil pump, can also be used as a sweep tank pump. And suitable for land oil depot, oil tanker and other storage device oil transport. Can also be used to transport sea water, fresh water and so on. It has the characteristics of simple structure, easy operation and maintenance, smooth operation, large displacement, high efficiency, easy to adjust, strong self-priming ability, wide application range and so on.
