YW type non-clogging submerged sewage pump

1. Product overview of YW type non-clogging submerged sewage pump

YW type non-clogging submerged sewage pump referred to as submerged pump is a new generation of pump products successfully developed on the basis of the introduction of foreign advanced technology and combined with the use characteristics of domestic pumps. Features such as installation and automatic control. It has a unique effect in discharging solid particles and long-fiber waste. This series of pumps adopts a unique impeller structure and a new type of mechanical seal, which can effectively convey solids and long fibers. Compared with the traditional impeller, the impeller of the pump adopts the form of single flow channel or double flow channel. It is similar to a curved pipe with the same cross-section and has very good flow capacity. With a reasonable volute chamber, the pump has high efficiency. The high and the impeller have been tested for dynamic and static balance, so that the pump has no vibration during operation.

2. Product features of YW type non-clogging submerged sewage pump

1. The unique single-piece or double-blade impeller structure greatly improves the ability of dirt to pass through, and can effectively pass through 5 times the fibrous material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.

2. The mechanical seal adopts a new type of hard and corrosion-resistant titanium tungsten material, which can make the pump run safely and continuously for more than 8,000 hours.

3. The overall structure is compact, the volume is small, the noise is low, the energy saving effect is remarkable, and the maintenance is convenient. There is no need to build a pump room, and it can work by diving into the water, which greatly reduces the project cost.

4. The pump has compact structure, small volume, convenient movement and simple installation.

5. It can be equipped with an automatic liquid level control cabinet, which can automatically control the start and stop of the pump according to the required liquid level change, without the need for special personnel to take care of it, and it is extremely convenient to use.

6. The sewage pump is a vertical structure. When working, the pump body is immersed in the liquid, so it is easy to start. There is no problem of exhaust and evacuation. At the same time, it has the characteristics of no leakage.

7. The shaft connection structure is advanced and reliable. The pump and the motor are connected by a shaft coupling. The size of the pump shaft is precise, which ensures the smooth operation of the pump and leaves a sufficient safety factor.

8. The pump has two types: single-pipe installation and double-pipe installation.

3. The main purpose of YW type non-clogging submerged sewage pump

Suitable for chemical, petroleum, pharmaceutical, mining, paper industry, cement plants, steel plants, power plants, coal processing industries, as well as urban sewage treatment plant drainage systems, municipal engineering, construction sites and other industries conveyor belt particles of sewage, dirt, It is also used for pumping clean water and corrosive media.
■ Precautions for the use of YW type non-clogging submerged sewage pump:
1. Before using the pump, carefully check whether the pump and motor are damaged. Check the tightening condition of the fasteners.
2. Check whether there is a friction sound in the disc-driven pump. Check the concentricity of the pump shaft and the motor shaft together. The deviation of the outer circle of the two couplings does not exceed 0.5mm.
3. The pipeline connected to the pump outlet should be provided with a separate bracket. It is not allowed to add its weight to the pump body.
4. The water pump must be equipped with a fully active water pump control cabinet under no special circumstances. Do not directly connect to the power grid or use a knife switch to connect the current to ensure the normal operation of the water pump.
5. Do not run the pump at a low lift for a long time (usually, the lift should not be lower than 60% of the additional lift). The best way to control it is within the range of lift recommended to prevent the pump from burning out the motor due to overloading.
■ Instructions for use of YW type non-clogging submerged sewage pump:
  start:
    1. Start the experiment to check whether the motor steering and pump requirements are consistent.
    2. Close the valve and pressure gauge on the outlet pipeline.
    3. Start the motor, open the rear pressure gauge, and gradually open the outlet pipeline valve to the desired position. until normal operation.
  Parking:
    1. Gradually close the outlet gate valve, stop the motor, and close the pressure gauge.
    2. When parking for a long time, the pump should be removed, please reinstall it and keep it properly.
  open:
    1. Close the valve of the liquid outlet pipe and remove the joint bolts on the flange.
    2. Loosen the bolts of the motor base and the connecting end cover, and remove the motor.
    3. Loosen the bolts that fix the pump on the foundation, take out the pump, and flush it with clean water to prevent oxidation.
    4. Remove the base, pump body and liquid outlet pipe, loosen the impeller nut, and take out the impeller.
    5. Remove the oil chamber and mechanical seal, remove the extension tube, bearing seat, and take out the extension shaft.

Suitable for chemical, petroleum, pharmaceutical, mining, paper industry, cement plants, steel plants, power plants, coal processing industries, as well as urban sewage treatment plant drainage systems, municipal engineering, construction sites and other industries conveyor belt particles of sewage, dirt, It is also used for pumping clean water and corrosive media.
