QW type non-blocking submersible sewage pump 1. Product overview:
1. The large flow channel anti-clogging hydraulic component design greatly improves the ability of passing through the dirt and can effectively pass through 5 times the fiber diameter of the pump aperture and about 50% of the solid diameter of the pump aperture.
2. The design is reasonable, the supporting motor is reasonable, the efficiency is high, and the energy saving effect is significant.
3. The mechanical seal adopts double-track series seal and is made of hard wear-resistant tungsten carbide. It has the characteristics of durability, wear resistance, etc. It can make the pump run continuously for more than 800 hours.
4. The pump is compact, small in size, easy to move, and easy to install. It does not need to build a pump room, and can work in submerged water, greatly reducing the project cost.
5. There is an oil probe in the pump oil chamber. When the mechanical seal on the pump side is damaged, water enters the oil chamber and a signal is generated on the probe to protect the pump.
6. According to the needs of users, it can be equipped with a fully automatic safety protection control cabinet to monitor the leakage, leakage, overload and over-temperature of the pump to ensure the reliable and safe operation of the pump.
7. The dual-rail automatic coupling installation system brings great convenience to the installation and maintenance of the pump installation. People do not need to enter or leave the sump.
8. Float switch can be changed according to the required water level. Automatic control of the pump stop without special care.
9. Ensure that the motor is not overloaded during the use of the head range.
10. According to the occasion of use, the motor can use a water jacketed external third party circulating cooling system, which can ensure the safe operation of the electric pump under the condition of no water (dry).
11. There are two kinds of installation methods: fixed automatic coupling installation and mobile free installation, which can meet different occasions.
Second, the structure description
QW type non-blocking submersible sewage pump is composed of two parts: the motor and the pump. The two are separated by an oil isolation chamber and a mechanical seal assembly. It is an electromechanical integration product. The motor and the pump share the same shaft (rotor). The entire pump has a short length and a compact structure. . Equipped with a variety of protective devices, making the pump reliable, its main components function as follows:
Signal Line 1: Equipped with a full-safety water pump control cabinet, which implements all-round protection for the pump, including leakage, phase failure, short circuit, overheating, motor overload, etc. Motor stator 8: Class B or Class F insulation.
Leak probe 11: This component is installed in the oil chamber. When the mechanical seal is damaged, water enters the oil chamber. The probe can send a signal to protect the pump from the control system.
Mechanical seal 13: Adopt double-track series seal, and adopt new hard tungsten carbide material with reliable sealing, wear-resisting and long life.
Impeller 17: The impeller adopts a single runner or double channel structure, has a strong ability to pass through, and can pass through large materials and fiber waste to reduce the failure of plugging and winding.
Pump body 15: Used with the impeller, making the pump highly efficient.
Sealing ring 18: installed in the ring of the pump body. When the impeller is worn due to running, the sealing ring can be replaced to ensure that the pump runs at optimum efficiency.
