Problems solved by technology

[0006] How to solve the problem that the self-priming sewage pump is easy to block; in one aspect disclosed by the embodiment of the present invention, the set filter pipe, the screening seat and the screen can be used together to solve the problem that the self-priming sewage pump is easy to block. The water is drawn from the pumping area, and the water flow enters the filter pipe through the suction pipe. When the water flow passes through the filter pipe and moves to the side of the water inlet connection, the screening seat filters and screens the sundries in the water flow, and the sieve mesh filters the water flow. The debris is filtered and isolated, and the screening seat can be rotated back and forth inside the filter tube through the connecting column. Through several diversion holes and screens, the water flow can be diverted, and the blocking effect of the screening seat on the water flow can be slowed down. ;The filtered water flows into the impeller through the water inlet connection pipe, and the water flow is delivered to the water outlet connection pipe through the rotation of the impeller, and the water flow is discharged through the water outlet connection pipe. After the pumping is completed, the motor is stopped, and the backflow of the water flow is prevented through the check valve; Effectively filter and screen the sundries in the sewage to prevent foreign matter from entering the self-priming sewage pump, eliminate the impact of sundries on the work of the self-priming sewage pump, and effectively improve the suction effect of the self-priming sewage pump;
[0007] How to solve the problem of observing and treating the sundries filtered in the self-priming sewage pump; in another aspect disclosed in the embodiment of the present invention, the joint use of the provided connecting ring, fixing hole, and the first observation window and the second observation window can Solve the problem that the debris filtered in the self-priming sewage pump is inconvenient to observe and deal with; by fixing one end of the filter pipe with the water inlet pipe thread, the other end of the filter pipe is connected with the suction pipe through the connecting ring, and the suction pipe One end of the pump is placed in the pumping area for pumping, and the screening of debris on the screen is observed through the first observation window and the second observation window. After the pumping is completed, the suction pipe is separated from the filter pipe, and the filter pipe is separated from the water inlet. The filter tube is placed horizontally on the ground to clean up the sundries on the screen, which is convenient for observing the filtering situation of the sundries, facilitates timely cleaning of the sundries, and eliminates the impact of sundries on the work of the self-priming sewage pump to improve work efficiency

Embodiment 2

[0050] The pump body 4 is transported through the support base 1 and installed on the ground of the pumping area. For example, the pumping area can be a sewage pool, and the sewage pool contains a large amount of fiber or floc. After the support base 1 is fixed and installed, the Turn the water injection valve counterclockwise to open the water tank 7, and then inject liquid storage water into the water tank 7. After the water injection is completed, turn the water injection valve clockwise to close the water tank 7 through the water injection valve, and connect one end of the filter tube 8 to the water inlet. 6 thread fixed connection, the other end of the filter pipe 8 is connected to the water suction pipe through several fixing holes on the connecting ring 9, and one end of the water suction pipe is placed in the sewage pool;

[0051] Turn the inlet one-way valve 13 counterclockwise, so that the water inlet pipe 6 forms a passage, turn on the power to start the motor 2, and...

Abstract

The invention discloses a high-suction-stroke self-priming sewage pump not prone to being blocked. The problem that a self-priming sewage pump is prone to being blocked can be solved through cooperative use of a arranged filter pipe, a screening base and a screen, water flow backflow is prevented through a check valve, impurities in sewage can be effectively filtered and screened, foreign matter is prevented from entering the self-priming sewage pump, the influence of the impurities on the work of the self-priming sewage pump is eliminated, and the suction stroke effect of the self-priming sewage pump can be effectively improved. A connecting ring, a fixing hole, a first observation window and a second observation window match for use, so that the problem that the impurities filtered in the self-priming sewage pump are inconvenient to observe and treat can be solved, the screening condition of the impurities on the screen is observed through the first observation window and the secondobservation window, the filter pipe is horizontally placed on the ground, and the impurities on the screen are washed and cleaned through purified water, so that the filtering condition of the impurities is conveniently observed, the impurities are conveniently cleaned in time, the influence of the impurities on the work of the self-priming sewage pump is eliminated, and the working efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of self-priming sewage pumps, in particular to a self-priming sewage pump with a high suction range that is not easy to be blocked. Background technique [0002] Sewage pump is a kind of centrifugal impurity pump, which is mainly used to transport urban sewage, feces or liquid containing solid particles such as fibers and paper scraps. Since the transported medium contains fibers that are easy to entangle or bunch, this This kind of pump is easy to block. Once the pump is blocked, the pump will not work normally, or even burn the motor, resulting in poor sewage discharge, which will have a serious impact on urban life and environmental protection. At the same time, if the sewage pump is running, the suction exceeds the critical value. value, then the sewage pump will have cavitation, abnormal vibration, noise, process drop, head drop, and damage to the impeller, bearing, and sealing components.
