WQ submersible sewage pump product overview:

1. Adopting a large channel anti clogging hydraulic component design greatly improves the ability of pollutants to pass through, effectively passing through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. Reasonable design, reasonable matching motor, high efficiency, energy-saving *.
3. The mechanical seal adopts a dual channel series seal, made of hard and wear-resistant tungsten carbide, which has the characteristics of durability and wear resistance, and can ensure the safe and continuous operation of the pump for more than 800 hours.
4. The pump structure is compact, small in size, easy to move, and easy to install, without the need to build a pump room. It can work underwater, greatly reducing project costs.
5. There is an oil-water probe installed in the oil chamber of the WQ submersible sewage pump. When the mechanical seal on the pump side is damaged and water enters the oil chamber, the probe generates a signal to protect the pump.
6. A fully automatic safety protection control cabinet can be equipped according to user needs to monitor pump leakage, electric leakage, overload, and overheating, ensuring reliable and safe pump operation.
7. The dual rail automatic coupling installation system brings convenience to the installation and maintenance of pumps, and people do not have to enter and exit the sewage pit for this.
8. The float switch can change according to the required water level. Automatic control of pump stop and start, no need for dedicated personnel to supervise.
9. Ensure that the motor operates without overload within the range of head.
10. According to the usage scenario, the motor can adopt a water jacket external DI three element circulating cooling system, which can ensure the safe operation of the electric pump in a dry state without water.

The QW type unobstructed submersible sewage pump consists of a motor and a pump, which are separated by an oil isolation chamber and mechanical seal components. It is an electromechanical integrated product, and the motor and pump share the same shaft (rotor). The entire length of the water pump is short and the structure is compact. Equipped with multiple protective devices to ensure reliable operation of the pump, its main components function as follows:
Signal line 1: Equipped with a fully protected water pump control cabinet to protect the pump, including water leakage, phase failure, short circuit, overheating, motor overload, and other items Motor stator 8: adopts B-level or F-level insulation.
Leakage probe 11: This component is installed in the oil chamber. When the mechanical seal is damaged and water enters the oil chamber, the probe can send a signal to the control system to protect the pump.
Mechanical Seal 13: Adopting a dual channel series seal and using a new type of hard and corrosion-resistant tungsten carbide material, it has the characteristics of reliable sealing, wear resistance, and long service life.
Impeller 17: The impeller adopts a single channel or double channel structure, which has strong passing capacity and can pass large materials and fiber garbage, reducing blockage and entanglement failures.
Pump body 15: Paired with the impeller, the pump has high efficiency.
Sealing ring 18: installed at the mouth ring of the pump body. When the impeller wears out the mouth ring due to operation, the sealing ring can be replaced to ensure that the pump operates at a better efficiency.

operation control
(1) The pH value of the absorption tower slurry is the core of the wet desulfurization system reaction process. Increasing the pH value of the slurry and adjusting the desulfurization operating parameters in a timely manner due to excessive slurry density can easily cause scaling on the pipe wall or hinder the inlet filter screen. Therefore, it is necessary to analyze the parameter status through data analysis to maintain it in an optimal state.
(2) Operators should improve their operational skills and equipment inspection quality. When the slurry circulation pump is stopped, pipeline flushing should be strengthened to prevent residual slurry in the pipeline. During equipment inspection, carefully observe the oil level, oil quality, cooling water return flow rate, and equipment appearance. Use thermometers and vibration meters to measure the temperature and vibration of the equipment. If any abnormalities are found in the equipment, decisive measures should be taken, such as adding lubricating oil to the bearing box or switching to the standby pump for operation. During the pump shutdown period, maintenance personnel should promptly repair the equipment, and warehouse personnel should prepare spare parts for the equipment to ensure timely replacement and normal operation.
(3) The process water system is an important guarantee for the operation of equipment. The slurry circulation pump requires cooling water for sealing and cooling, and the reducer also needs cooling water for cooling. Therefore, it is necessary to ensure the normal operation of the process water system. The inlet filter screen of the process water pump can filter impurities, so that the pipeline can be unobstructed, and the service life of the mechanical seal dynamic and static rings can also be extended. The outlet of the process water pump maintains normal pressure in order to have sufficient water to cool down the equipment, and the sealing water in the machine seal can also better block the leakage of the slurry.

1. The natural environment of chemical plants. Chemical plant liquids, such as strong acid and alkali liquids, corrosive liquids. Electric motors are generally above the liquid level, while pump casings are below the liquid level. Materials commonly used include rubber products, fluoroplastics, aluminum alloys, fiberglass reinforced plastic, and other anti-corrosion properties.
2. Industrial wastewater from wastewater pits. If the wastewater pit is generally shallow, choose a submersible pump for sewage treatment, with YW type submersible sewage pump models and specifications. If there is a lot of drilling mud in the wastewater, use NL mud pump. NL mud pumps are all submersible pumps, which can extract more viscous drilling mud due to the diversity of design schemes.
3. The natural environment of the sea surface. The sea surface contains weak corrosion, so using an underwater pump is very suitable. Easy and convenient installation, with the electric motor above and below the sea surface, it is a common pump in seawater desalination processing plants.
4. A natural environment with a high underwater depth of 1. Some loads are relatively heavy in natural environments, with varying depths of 15-12 meters underwater. If a submersible pump or submersible sewage pump is used, the cable will be immersed in the liquid for a long time and will gradually oxidize and corrode by air, resulting in a low safety factor. But choosing a submersible pump prevents the problem of electric motors and cables being submerged in the liquid.
