1. How to use and precautions for WQ non-clogging sewage pump
1. Before using the WQ submersible sewage pump, you should carefully check whether the cable is damaged, whether the fasteners are loose or fallen off, and whether the pump is deformed or damaged during transportation, storage, and installation.
2. Use a 500V megohmmeter to measure the insulation resistance between the same and the opposite ground of the electric pump motor. The value should not be less than 2 megohms. Otherwise, the motor stator winding should be dried. The temperature of the drying process is not allowed to exceed 120°C.
3. This series of pumps can be installed in two types: fixed type and mobile type. When using fixed automatic installation, the chain cables should be inserted into two lifting eye screws or lifting plates (deviated from the pump outlet, and the connection should be parallel to the pump outlet) to lift the electric pump up and down. Slide down the rail evenly and slowly until the automatic coupling is in place. When using mobile installation, first cover the hose and use the chain rope to pass through the two lifting rings to lift the electric pump up and down. Be careful not to use the cable as a rope to avoid danger.
4. The rotation direction of the WQ submersible sewage pump after it is connected is counterclockwise when viewed from the water inlet. If the electric pump is reversed, just swap any two wires in the cable to the wiring position.
5. The ground wire of the electric pump's casing must be connected strictly in accordance with relevant regulations. In order to ensure personal safety during use, it is strictly prohibited to install, operate or move the electric pump nearby when the electric pump is running, in case the electric pump leaks electricity. And an accident occurred.
6. The electric pump must be equipped with a fully automatic water pump control cabinet unless there are special circumstances. Do not directly connect it to the power grid or use a knife switch to connect the power supply to ensure the normal operation of the electric pump.
7. The electric pump must not be operated in a low-lift state for a long time (generally, the operating lift shall not be less than 60% of the rated lift). It is best to control the operating lift within the recommended range to prevent the electric pump from burning out the motor due to overloading.
8. Pumps without self-circulating cooling devices are strictly prohibited from being exposed to the water for long-term operation to prevent overheating and damage to the electric pump.
2. WQ non-clogging sewage pump maintenance
1. The electric pump should be managed and used by dedicated personnel, and the insulation resistance between the electric pump winding and the casing should be checked regularly to see if it is normal.
2. After each use, especially for thicker and more viscous slurries, the electric pump should be put into clean water and run for a few minutes to prevent sediment from leaving in the pump and ensure that the electric pump
Pump cleaning.
3. If the electric pump is not used for a long time, the electric pump should be taken out of the water and should not be soaked in water for a long time to reduce the chance of the motor stator winding getting damp and increase the service life of the electric pump. ^
4. Under normal conditions, the engine oil in the oil chamber (No. 10-?30 engine oil) should be added or replaced after every 300-500 hours of use of the pump to keep the mechanical seal well lubricated.
slippery state to increase the service life of the mechanical seal.
5. After the electric pump is disassembled and repaired, the casing components must be inspected by a 0.2MPa air tightness test to ensure that the motor seal is reliable.
6. The sealing ring between the impeller and the pump body has a sealing function. If the seal is damaged, it will directly affect the performance of the pump and should be replaced if necessary.

Principles for selecting sewage pumps - DFIN Pump Industry
1. High mechanical reliability, low noise, and minimal vibration.
2. Economically, it is necessary to comprehensively consider the total cost of equipment, operation, maintenance, and management fees to minimize them.
3. Make the selected pump type and performance meet the requirements of process parameters such as device flow rate, head, pressure, temperature, cavitation flow rate, and suction stroke.
4. Must meet the requirements of medium characteristics.
For pumps that transport flammable, explosive, toxic, or valuable media, reliable shaft seals or leak free pumps are required, such as magnetic drive pumps, diaphragm pumps, and shielded pumps
For pumps transporting corrosive media, it is required that the convection components use corrosion-resistant materials, such as AFB stainless steel corrosion-resistant pumps and CQF engineering plastic magnetic drive pumps.
For pumps transporting media containing solid particles, it is required that the convection components be made of wear-resistant materials, and if necessary, the shaft seal should be flushed with clean liquid.
