The self priming trash pump is a non-blocking self-priming sewage pump with self-priming function, which is developed to replace the submersible sewage pump product, avoiding the phenomenon that the pump is immersed in the water and is prone to water leakage, which is caused by water leakage. It can be used as a general clean water self-priming pump without installing a bottom valve, without priming water, and sucking dirt and sediment containing a large particle solid diameter of 60% of the outlet diameter and a fiber length of 1.5 times the diameter of the impeller. Waste mineral impurities, manure treatment and all engineering sewage and colloidal liquids, completely reduce the labor intensity of manpower, and easy to install and use, minimal maintenance, advanced performance, with a broad application market and development.
The self priming trash pump body is provided with a liquid storage chamber, and communicates with the pump working chamber through the upper return hole and the lower circulating hole to form an axial flow-flow external mixing system of the pump. After the pump stops working, a certain volume of liquid has been stored in the pump chamber. When the pump starts, the liquid in the relevant authority is thrown up by the air under the action of the impeller, and the liquid is returned to the working chamber through the grid of the gas-liquid separation tube, and the gas is discharged outside the pump, so that the pump is formed. The degree of vacuum reaches the effect of self-priming.
Main features of self priming trash pump:
1. It can be used within the design range to ensure that the motor will not be overloaded;
2. The mechanical seal of the self-priming sewage pump adopts a new type of grinding pair, and it is put into the oil chamber for a long time;
3. The overall structure is compact, the volume is small, the sound is small, the energy saving effect is remarkable, the maintenance is convenient, and the user is convenient to replace;
4. The self-priming sewage pump adopts the double-blade impeller structure, which greatly improves the ability of the dirt to pass through;
5, can be equipped according to the needs of users, it provides great convenience for installation and maintenance, people can enter the sump without this;
6. The self-priming sewage pump is equipped with an outdoor motor, so there is no need to build a pump room, and it can be directly installed and used outdoors to save money;
7. The automatic control cabinet can automatically control the over-motion and stop of the pump according to the required liquefaction change, without special care, and is extremely convenient to use;
The self priming trash pump is suitable for the discharge of serious polluted wastewater from the factory, the sewage discharge station in the main residential area, the water distribution system of the urban sewage treatment plant, the drainage station of the civil air defense system, the water supply equipment of the water supply plant, the sewage discharge of the hospital and the hotel, and the municipal Engineering construction sites, mine supporting machines, rural biogas digesters, farmland irrigation and other industries, conveyor belt particles of sewage, dirt, can also be used for clean water and with weak corrosive media.
