People often wonder how to solve the problems of rainy precipitation, sewage caused by construction sites, sewage caused by bathhouses, and such turbid water? How to discharge pollutants into the pipelines of big cities? The solution and discharge of sewage require the use of sewage treatment equipment - high standard unobstructed sewage pumps. Below is an explanation of the performance and advantages and disadvantages of non clogging sewage pumps.
The high standard unobstructed sewage pump consists of three parts: water pump, seal, and electric motor. The electric motor is located at the upper part of the electric pump and is a single-phase or three-phase asynchronous motor; The water pump is located at the lower part of the electric pump and has a double channel impeller and volute structure; Hard mechanical seals are used between the water pump and the motor, and "O" - shaped oil resistant rubber seals are used for static sealing at each fixed stop.
1, Structural characteristics
1. The stainless steel material of the electric pump shaft can effectively improve the wear resistance and corrosion resistance of the shaft, while also facilitating the maintenance and disassembly of the impeller.
2. Reliable waterproof cable entry: Even if the cable is damaged or the wire end is immersed in water, water will not enter the motor. It will not cause insulation degradation due to moisture in the environment, as water vapor is sucked into the motor through the gap between the copper wires of the cable
3. 7.5KW and below electric pumps are equipped with thermal protectors, which can automatically cut off the power supply to protect the motor in case of phase loss, overload, motor overheating, etc
4. The insulation level of the motor is Class B, and the designed output power has sufficient margin. All series of electric pumps can operate at full head.
5. The screw material at the contact part of the water pump is stainless steel 304, which is conducive to maintenance and disassembly.
2, Usage conditions
1. Water temperature: 0~50 ℃
2. The pH value of the water source is 4-10
3. The medium density shall not exceed 1.2 × 10m ³ kg/m3
4. Power supply voltage: 220V for single-phase, 380V for three-phase, 420V for special, frequency 50HZ, voltage fluctuation range of 0.8-1.2 times the rated value
3, Usage purpose
Wastewater discharge from factories, shopping malls, hospitals, and hotels
Domestic sewage and rainwater discharge in residential areas, parking lots, and municipal engineering projects
Wastewater discharge from sewage treatment plants and livestock farms
Pumping of slurry and greywater from construction sites and mines
Fresh water pumping for agriculture and aquaculture
Water supply and drainage in other occasions
