WQX down-suction high-lift sewage pump
Flow range: 12.5-100m³ / h
Head range: 15-200m
Caliber range: 50mm
Power range: 3-63KW
Temperature range: ≤50 ℃
WQX down-suction high-lift sewage submersible electric pump is suitable for pumping and dredging sewage and sludge in various harsh environments. The electric pump is a down-pump type that can drain the surface water of the working surface; the motor is a submersible three-phase asynchronous motor It can work in the water for a long time or work out of the water. It covers a small area, is easy to install and use, reliable and durable, and has a long life. This series of pumps have small flow, high head, small motor power, light weight and convenient movement.
Conditions of Use:
全不锈钢材质 也可用于抽送带腐蚀性介质。 Mainly used in chemical industry, petroleum, pharmaceutical, mining, papermaking industry, cement plant, steel plant, coal processing industry of power plant, and sewage system of municipal sewage treatment plant, municipal engineering, construction site and other industries. All stainless steel can also be used for pumping corrosive media.
Structural characteristics and working principle:
WQX 型下泵式工程用潜水电泵由潜水三相异步电动机和污水泵两大部分组成。 1. WQX type submersible pump for engineering use consists of two parts: submersible three-phase asynchronous motor and sewage pump. The motor is directly connected to the lower pump body, and a reliable shaft seal (mechanical seal) device is provided in the middle, which can effectively prevent the exchange between the coolant in the motor and the pumped medium, and ensure the long-term safe and reliable operation of the pump.
2. The motor winding is a nylon-sheathed polyethylene edge water-resistant electromagnetic wire. The inner cavity of the motor is filled with water, and the performance of the motor has been greatly improved in harsh environments.
3. It is equipped with a steel water jacket, and the conveying medium passes through the water jacket interlayer to cool the motor. Even if the motor is exposed to the water surface, it can work safely. Multi-stage or single-stage submersible pumps are available in ordinary materials and all stainless steel.
4 , using high-quality rolling bearings to support and effectively lubricate, by adjusting the bearing assembly process to effectively solve the problem of pump damage to the bearing.
5. The motor shaft is made of stainless steel or chrome-plated carbon steel, and the shaft diameter is thickened to improve the coaxiality and rigidity of the rotating parts, which effectively solves the problem of the traditional pump easy to break the shaft,
6. The shell is made of internationally popular steel stamping, drawing and welding. The surface is sprayed with resin, which is several times more anti-corrosive and wear-resistant than conventional pumps. The color is bright and beautiful.
