Product overview

WQ non-clogging submersible sewage pump is a new generation of pump products successfully developed on the basis of the introduction of foreign advanced technology, combined with the characteristics of domestic water pumps. It has the characteristics of significant energy saving effect, anti-winding, non-clogging, automatic installation and automatic control. In the discharge of solid particles and long fiber garbage, has a unique effect.
This series of pumps adopts unique impeller structure and new mechanical seal, which can effectively transport solids and long fibers. Compared with the traditional impeller impeller, the pump impeller with single or double channel form, it is similar to the 1 section of the same size elbow, has a very good flow, with a reasonable worm chamber, making the pump has high efficiency, impeller by static and dynamic balance test, so that the pump in operation without vibration.
The hydraulic performance of the pump is advanced and mature, and the performance indicators of the product have been tested to meet the relevant standards. After the product is put on the market, it is welcomed and praised by the majority of users for its unique efficacy, reliable performance and stable quality.

Product Features

1, The use of large channel anti-clogging hydraulic component design, greatly improving the dirt through capacity, can effectively through the pump diameter of 5 times the fiber material and the diameter of the pump diameter of about 50% of the solid particles.
2. Reasonable design, reasonable supporting motor, high efficiency and remarkable energy saving effect
3. The corrosion resistance and resistance of the pump shaft are greatly improved by chrome plating, and the service life of the whole pump is significantly improved. 4. The whole vulcanization technology of rubber sleeve is adopted at the connection between cable and motor, and its waterproof effect is long-lasting and reliable.
5. The mechanical seal adopts double series seal, the material is hard corrosion-resistant tungsten carbide, which is durable and wear-resistant, and can make the pump safe and continuous
Run more than 8000 hours.
6. The pump has compact structure, small size, convenient movement, easy installation, and no need to build a pump room. Dive into the water can work, greatly reducing the cost of the project.
7. Oil-water probe is arranged in the pump oil chamber. When the mechanical seal on the pump side is damaged, water enters the oil chamber, and the probe generates a signal to protect the pump.
8. It can be equipped with automatic safety protection control cabinet according to user's needs to monitor the leakage, leakage, overload and overtemperature of the pump to ensure the reliable and safe operation of the pump.

9, double rail automatic coupling installation system, to the pump installation, maintenance has brought great convenience, people do not have to go in and out of the sump.
10. The float switch can automatically control the stop and start of the pump according to the required water level change, and no special person is required to take care of it.
11, in the use of lift range to ensure that the motor is not overloaded.
12, according to the use of the motor can be used in the water jacket type external circulation cooling system, can ensure the safe operation of the electric pump in the anhydrous (dry) state.
13. There are 2 installation methods: fixed automatic coupling installation and mobile free installation, which can meet different use occasions.

Pump usage conditions

1. The medium temperature does not exceed 60 ℃, the weight is 1.0-1.3kg/dm³, and the pH value is within the range of 5-9.
2. For pumps without internal self circulating cooling systems, the exposed liquid level of the motor part should not exceed 1/2.
3. In general, the pump must be used within the range of head to ensure that the motor is not overloaded. If it needs to be used within the full head range, it should be specified separately when ordering for the manufacturer to manufacture.
4. The current of the pump motor during operation shall not exceed the rated current of the motor.

Structural description

The WQ 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 safe and reliable operation of the pump. The main functions of its components are as follows:
Signal line 1: Equipped with a fully protected water pump control cabinet to provide all-round protection for the pump, including water leakage, phase failure, short circuit, overheating, motor overload, and other items. Motor stator 8: using B-class or F-class 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 implement the pump
Protection. Mechanical seal 13: Adopting dual channel series sealing, using a new type of hard and corrosion-resistant tungsten carbide material, which has the characteristics of reliable sealing, durability, and long service life. Impeller 17: The impeller adopts a single or double channel structure, which has strong passing capacity and can pass through large materials and fiber waste, reducing the risk of blockage and entanglement.
Pump body 15: matched with impeller, making the pump highly efficient,
Sealing ring 18: installed at the mouth ring of the pump body. When the impeller is damaged at the mouth ring due to operation, the sealing ring can be replaced to ensure that the pump operates at the best efficiency
