A sewage pump is a pump product in which the pump and motor are integrated and work underwater simultaneously. Compared with general horizontal pumps or vertical sewage pumps, the sewage pump has a compact structure and a small footprint.It is easy to install and maintain. Large sewage pumps are generally equipped with automatic coupling devices for automatic installation. Installation and maintenance are very convenient.Long continuous operation time.Because the pump and the motor are coaxial, the shaft is short, and the rotating parts are light in weight, the load on the bearings (radial direction) is relatively small, and the service life of the sewage pump is much longer than that of ordinary pumps.There are no problems such as cavitation damage and water diversion.Especially the latter point brings great convenience to the operator.The vibration and noise are small, the temperature rise of the motor is low, and there is no pollution to the environment.
1. Understand the usage environment of the water pump and choose the correct water pump type (generally divided into wet type and dry type)
2. Calculate the required lift of the water pump.Sometimes customers include the flat ground conveying distance into the head. This is wrong. The flat ground conveying distance must be multiplied by the friction coefficient to calculate the head.
3. Pipe elbow wear, pipe friction, etc. must be taken into account. In actual situations, these are different, and it is quite troublesome to calculate accurately, so it is recommended to leave some space to ensure that the water pump can pump out water.
4. If you choose a stainless steel sewage pump, you must also find out the pH of the water quality, including particle diameter, etc., and choose the appropriate stainless steel material.Generally, 304 material is suitable for pH between 4 and 10. If it exceeds this range, it is recommended to use 316 or 316L stainless steel.
5. The water pump must be used within the rated lift range to ensure that the motor is not overloaded.
For example, if the actual required lift is 30 meters, but a water pump with a standard lift lower than 30 meters is used to pump water, this situation is a wrong usage method and will cause the motor to be overloaded. In serious cases, the motor will be burned out.
6. The water pump pipeline must be unblocked. If the pipeline is blocked, it will also cause the motor to be overloaded, and in serious cases, the motor will be burned out.
According to different sewage discharge methods, sewage pumps can be divided into self-priming sewage pumps, submerged sewage pumps, knife-type sewage pumps and automatic mixing sewage pumps.The vertical sewage pump adopts a unique single-blade or double-blade impeller structure, which greatly improves the dirt passing capacity and can effectively pass through fibrous materials that are 5 times the diameter of the pump and solid particles with a diameter of about 50% of the diameter of the pump.Vertical sewage pumps can be moved or fixedly installed. They are used for pumping and discharging sewage in construction, farmland drainage and irrigation, and enterprises and institutions. In addition to transporting sewage, they are also suitable for use as drainage pumps and pulp pumps. For irrigation, etc.
Purpose:
Wastewater discharge from enterprises and units.Municipal sewage treatment plant discharge system.Subway, basement, civil air defense system drainage station.Wastewater discharge from hospitals, hotels and high-rise buildings.Sewerage stations in residential areas.Municipal engineering, discharge of thin mud from construction sites.Water supply device of waterworks.Wastewater discharge from breeding farms and irrigation of rural farmland.
Product Features:
1. Large channel anti-blocking hydraulic component design, which can effectively pass through 25~125mm diameter solid particles;
2. The water jacket type circulating water cooling system is adopted for the motor, which can ensure the reliable operation of the electric pump without water (dry type) (above 15KW);
3. The unique motor anti-condensation device can automatically dehumidify the motor to ensure that the motor insulation is above 300M Ω under a high-temperature environment and the motor operates normally and reliably;
4. The automatic coupling system is adopted, which is easy to install without building the pump house, and can reduce a lot of project costs and operation costs;
5. The automatic protection system is provided with a multi-function operation display, which can centrally control various operation states and provide effective protection.
Working Conditions:
1. PH: 5~9
2. Water temperature not exceeding 60°C.
3. Impurity content (weight ratio) not more than 25%.
