Self controlled self-priming pump

The self controlled self-priming pump is a product that has been improved and innovated based on the advanced experience of relevant self-priming pump products at home and abroad, and is a replacement product for traditional similar products in China. This product has the advantages of temperature resistance, pressure resistance, wear resistance, "first drainage, permanent self-priming", etc. The product is made of materials such as cast iron, cast steel, stainless steel, and reinforced polypropylene. Various styles and specifications. This product has functions such as high efficiency, energy saving, and unique structure. After the product was launched on the market, it was welcomed and praised by a large number of users for its unique design and reliable quality, and was chosen by many units as a substitute for imported products.

Product features of self controlled self-priming pump:

1: The self suction pump without sealing is reliable and adopts a leak free sealing device, which is composed of a power seal and an auxiliary seal. Replaced the traditional water pump's packing seal and mechanical seal, completely solving the problems of 'running, emitting, dripping, and leaking' in traditional seals. It is the most ideal product to replace the original long axis submersible pump, submersible pump, submersible sewage pump, etc.

2: The sealing device of the self-priming pump operates without friction or wear, and its service life is more than 10 times longer than traditional products. The principle of transplanting vacuum pump has stable and reliable self-priming performance, especially with the use of an "electric air control valve" that truly achieves first drainage and permanent self-priming. The pump unit has low vibration, low noise, flexible movement, and easy disassembly and assembly. It has superior self-control function and can be matched with related control systems to achieve high automation.

The self controlled self-priming pump is mainly composed of pump body, impeller, pump cover, guide vanes, auxiliary impeller, pump shaft, connecting frame, electric air control valve and other parts. The interior of the pump body consists of a suction chamber, a storage chamber, a gas-liquid separation chamber, and other parts. After the pump starts normally, the impeller sucks in the liquid stored in the suction chamber and the air in the suction pipeline together. The liquid mixed gas is thrown into the gas-liquid separation chamber through the guide vanes under the centrifugal force of the high-speed rotation of the impeller. Due to the sudden decrease in flow rate and the difference in specific gravity between gas and liquid, lighter gases are separated from the mixed liquid and discharged outside the pump. The degassed liquid re enters the working chamber and mixes with the air sucked in from the suction pipeline inside the impeller. Under the rotation of the impeller, a certain degree of vacuum is quickly formed at the inlet of the pump body, thus achieving the purpose of self-priming. Due to its unique exhaust function, the pump can transport liquids containing gas without the need for a bottom valve. When the pump is equipped with an "electric air control valve" during operation, the control valve closes to achieve sealing; After shutdown, the control valve opens, breaking the vacuum in the suction pipeline and preventing the liquid in the pump chamber from flowing out of the suction pipeline due to the cylinder suction effect after shutdown. This allows sufficient liquid to be stored in the pump chamber to continue the self-priming process, thus achieving "first drainage, permanent self-priming".
