Working principle
No clogging sewage pump is mainly composed of pump body, impeller, rear cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water valve, inlet and exhaust pipe and so on.
The working principle of the pump is that there is a liquid storage cavity in the pump body, which is communicated with the pump working chamber through the upstream reflux hole and the lower circulating hole, and form an axial flow plus external mixing system of the pump. After the pump stops working, the inner cavity of the pump has been stored in a certain volume of liquid. When the pump starts, the storage fluid in the relevant authorities under the action of the impeller is carried up and the air is thrown upward. The liquid flows back to the working chamber through the grid of the gas-liquid separation pipe, and the gas is discharged out of the pump, so that a vacuum degree is formed in the pump, so as to achieve the function of self suction.
Product advantages
The non blocking sewage pump is a pump product connected to the pump and motor and submerged into the liquid at the same time. Compared with the general horizontal pump or vertical sewage pump, the non blocking sewage pump has the following advantages: 1., compact structure and small footprint. The sewage pump can be directly installed in the sewage pool because of its submerged operation. No need to build a dedicated pump house to install pumps and machines, it can save a lot of land and infrastructure costs.
2. installation and maintenance is convenient. The small sewage pump can be installed freely. The large sewage pump is equipped with automatic coupling device, which can be installed automatically. The installation and maintenance are quite convenient.
3. continuous operation time is long. Because of the pump and motor coaxial, the shaft is short and the weight of the rotating parts is light, so the load on the bearing (radial) is relatively small, and the life of the pump is much longer than that of the ordinary pump.
4. there are no cavitation damage and water diversion and other problems. In particular, the later point has brought great convenience to the operators.
5. small vibration and noise, low temperature rise, no pollution to the environment.
Product features
1. A double blade impeller structure has been adopted to greatly improve the ability to pass the dirt.
2, the mechanical seal adopts a new type of sassafras, and runs into the oil chamber for a long time.
3. It has compact structure, small volume, small dryness sound, remarkable energy saving effect, convenient maintenance and convenient replacement for users.
4. The automatic control cabinet can automatically control the pump's super movement and stop according to the change of the required liquefaction. It is very convenient to use without a special person to watch the tube.
5. The installation method can be installed according to the needs of the user. It is very convenient for installation and maintenance.
6. It can be used in the range of design, and the motor will not be overloaded.
7. The pump is equipped with an outdoor motor, and the pump room is not built. It can be installed directly and outdoors to save the expenses.
