Introduction of Long Shaft Pump

Long-axis pumps are suitable for conveying corrosive environmental media such as particles, high viscosity, strong acid, alkali, salt, strong oxidant, etc. on the conveyor belt of enterprises. The new submersible pump is suitable for conveying flammable and explosive light media. The shell, outlet pipe and current asset parts of the traditional submersible pump are all made of a kind of corrosion-resistant and material. The motor component is placed on the liquid surface, and the pump part is placed under the liquid surface. It has the characteristics of strong corrosion resistance, no blockage and high temperature resistance. The pump body, motor and flow parts of the new submersible pump are made of special materials. The motor is coaxially connected with the pump part and placed under the liquid surface. It is maintenance-free, has high explosion-proof performance, can be used in zero zone, and has low energy consumption.
The long-axis pump belongs to a type of centrifugal pump. From the perspective of the centrifugal pump, the performance of the liquid pump can be effectively improved. The pump can be used for enterprises to transport rainwater, iron oxide water, sewage, corrosive chemical industrial production wastewater, seawater and other working liquids. It is widely used in industrial enterprises such as water supply companies, sewage treatment plants, steel mills, mines, as well as municipal water supply and drainage, farmland irrigation, flood control, waterlogging, etc.
Long-axis pumps are mainly used to transport clean water, sewage containing certain solid particles (such as iron filings, sand, coal powder, etc.), corrosive industrial wastewater and seawater. They are widely used in primary water plants, sewage treatment plants, metallurgical and steel enterprises (especially mainly used to transport oxidized iron scale water in the cyclone pool of the industry), power plants, mines, municipal construction projects and farmland water conservancy system projects.
The motor of the long-axis pump is coaxially connected to the pump. It consists of a pump body, a pump head, a connecting system pipeline and a control working device. The pump body includes a shielded motor and a centrifugal pump, and the motor and the centrifugal pump are coaxially connected. The external suction cover forms an inseparable whole. It adopts the explosion-proof technical standard EXDIIBT4 design, belongs to GA-level equipment [3], and is suitable for use in zero zone. The main advantages of the design are: the bearing of the pump is only a few hundred millimeters, there is no long shaft, and it will not cause students to swing and produce some problems. The operation is stable, the sound can be very small, and there is almost no wear. The pump and the medium contact parts are generally made of special materials and are widely used in chemical plants, pharmaceutical plants, factory production lines, generator sets and other places where flammable and explosive media are transported.
The long-shaft pump is a vertical single-suction centrifugal pump. Its impeller is installed below the dynamic water level in the well. The power is mainly concentrated in the well. By raising the transmission long shaft to drive the impeller to rotate in the guide and casing, the water flows along the channel information between the guide casing and the impeller structure, and rises to the well surface through the water pipe. When the head is high, a centrifugal pump with multi-stage series impellers can be used. Due to the high manufacturing and installation precision, the efficiency decreases with the increase of the well depth, so it can only be used in deep wells below 100 meters.
