This type vertical sealless self-control self-priming sewage sewage pump is improved and innovated on the basis of absorbing advanced experience. The product has the advantages of temperature resistance, pressure resistance, wear resistance, "first drainage, permanent self-priming" and so on. The products are made of cast iron, cast steel, stainless steel, reinforced polypropylene and other materials. Various shapes and specifications. The sewage pump has the functions of high efficiency, energy saving and unique structure. After the product is put on the market, it is welcomed and praised by the majority of users for its unique design and reliable quality.
Product application
Structure diagram
It is mainly composed of pump body, impeller, pump cover, guide vane, auxiliary impeller, pump shaft, connecting frame, electric air control valve and other parts. The inside of the pump body is composed of a suction chamber, a liquid storage chamber, a gas-liquid separation chamber and other parts. After the pump is started normally, the impeller sucks the liquid stored in the suction chamber and the air in the suction pipeline together, and the liquid mixed gas is thrown into the gas-liquid separation chamber through the guide vane under the centrifugal force of the high-speed rotation of the impeller. Different from the specific gravity of the liquid, the lighter gas is separated from the mixed liquid and discharged out of the pump, and the degassed liquid re-enters the working chamber and re-mixes with the air sucked in from the suction pipe inside the impeller. It will soon form a certain degree of vacuum at the inlet of the pump body, so as to achieve the purpose of self-priming. Due to the unique venting function of the pump, the pump can deliver liquids containing gas without installing a foot valve. When the pump is equipped with an "electric air control valve", the control valve is closed to achieve sealing; after the shutdown, the control valve is opened, which destroys the vacuum in the suction pipeline and prevents the liquid in the pump cavity from being sucked in due to the cylinder suction after the shutdown. The pipeline flows out, so that enough liquid is kept in the pump cavity to continue the self-priming process, thus realizing "first drainage, permanent self-priming".
Features
The sealless self-control self-priming sewage pump has reliable sealing and adopts a leak-free sealing device, which is specifically composed of a dynamic seal and an auxiliary seal.
Advantages
The sealless self-controlling self-priming sewage pump has no friction and no wear during operation, and its service life is more than 10 times longer than that of traditional products. The self-priming performance of the transplanted vacuum pump is stable and reliable. Especially, the "electric air control valve" is used to truly realize the first drainage and permanent self-priming. The pump unit has low vibration, low noise, flexible movement and convenient disassembly and assembly. It has excellent automatic control function and can be matched with related control systems to achieve high automation.
