1、 Introduction to WQ submersible sewage pump
The WQ series submersible sewage pump is a product developed by our company based on the absorption of advanced technology from a well-known German pump manufacturing company. It has a high technical starting point, obvious energy-saving effect, strong compatibility, and wide applicability. After being launched on the market, it has been well received and praised by a large number of users for its unique functions and reliable quality, and has been selected as a substitute for imported products by many key construction projects in various countries.
2、 Characteristics of WQ submersible sewage pump
1. Adopting a large channel anti clogging hydraulic component design, it can effectively pass solid particles with a diameter of 25-125 millimeters.
2. The motor adopts a water jacket circulating water cooling system, which can ensure the reliable operation of the electric pump in a dry state without water (above 15KW).
3. The unique anti condensation device of the motor can automatically dehumidify the motor, ensuring that the insulation of the motor is above 300M Ω in high temperature environments, allowing the motor to operate normally and reliably.
4. Adopting an automatic coupling system, it is easy to install and does not require the construction of a pump room, which can reduce a large amount of engineering costs and lower operating costs.
5. The automatic protection system has a multifunctional operation display, which can centrally control various operating states and provide effective protection.
3、 Scope of application of WQ submersible sewage pump
1. The discharge of serious wastewater from factories and businesses.
2. Sewage drainage in residential areas, hospitals, and hotels.
3. The water supply and drainage of the water plant.
4. Urban sewage treatment plant water supply and drainage system.
5. Civil air defense system drainage, municipal engineering, construction sites.
6. Irrigation of farmland, exploration, and supporting machinery for mines.
4、 Structural Description of WQ Submersible Sewage Pump
This series of submersible sewage pumps has introduced and absorbed advanced foreign technology, with a reasonable structure and superior performance. The squirrel cage motor operates in S1 mode, with a stator insulation level of F (155 ℃) and an anti condensation device. Each phase is equipped with overload protection components.
5、 Precautions for using WQ submersible sewage pump
1. High medium temperature: When the AS submersible sewage pump is used continuously, it is about 40 ℃, and when used intermittently (not exceeding 5 minutes), it is 80 ℃.
2. The main component material of the submersible sewage pump is cast iron, so it cannot be used for pumping highly corrosive liquids.
3. Never lift or suspend the cable or water pump.
4. To extend the service life of the water pump, it is necessary to regularly add or replace the oil (10 # oil) in the oil chamber to improve the service life of the mechanical seal.
5. When customers install automatic coupling devices, they need to determine the length of the guide rail (standard length is 3M).
