Description
Technical Field
The utility model relates to a self priming pump especially relates to a take electronic supplementary exhaust apparatus's automatic control self priming pump.
Background
The self-priming pump without seal has one non-return valve in the outlet to prevent the vane wheel from rotating reversely and to prevent the liquid from flowing fast out of the auxiliary vane wheel and the electric air control valve. The outlet check valve of such pumps generally employs a simple swing or lift check valve. The check valve does not require complete sealing, so the valve plate is generally made to be rough and has heavier dead weight, and in addition, liquid exists in an outlet pipeline after the self-priming pump is shut down. This is particularly true for large flow self-priming pumps, where the check valve plate of a large pump is heavier and a small amount of water stored in the outlet line generates a large pressure.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a following scheme:
the utility model provides a take electronic supplementary exhaust apparatus's automatic control self priming pump, includes the pump body, sets up the impeller in the pump body, and pump body both sides set up inlet tube and outlet pipe respectively, and the outlet pipe is provided with the check valve, and pump body top sets up and is used for driving impeller pivoted motor, and the motor outer wall is provided with the terminal box, the intercommunication has auxiliary exhaust pipe between the outlet pipe lateral wall at pump body top surface and check valve rear, is provided with the solenoid valve on the auxiliary exhaust pipe.
Furthermore, the auxiliary exhaust pipe is made of stainless steel, and two ends of the auxiliary exhaust pipe are respectively connected with the side wall of the water outlet pipe and the top surface of the pump body in a seamless mode.
Furthermore, the electromagnetic valve is electrically connected with the junction box and is in a normally closed state.
The top surface of the pump body of the self-control self-priming pump is provided with a hole, the side wall of a water outlet pipe at the rear end of a check valve plate is provided with a hole with the same size, the hole is connected by an auxiliary exhaust pipe, the middle position of the auxiliary exhaust pipe is connected with a normally closed electromagnetic valve, and the electromagnetic valve and an electric air control valve are connected in a junction box in the same way. When the self-priming pump is started, the electromagnetic valve is opened, air separated from the valve body is discharged to the water outlet pipe through the electromagnetic valve without passing through the check valve, after the air in the water inlet pipe of the pump is exhausted, the pressure in the pump begins to be increased, liquid after the pressure is increased is enough to push away the valve plate of the check valve, and the self-control self-priming pump can normally work.
The electric auxiliary exhaust device of the large-flow self-control self-priming pump has the advantages that: the structure is comparatively simple, easily makes, can guarantee that self-control self priming pump can both normal boot at every turn. Compared with the common self-control self-priming pump, the self-control self-priming pump with the electric auxiliary exhaust device can greatly shorten the self-priming time, and is very suitable for a large-flow self-control self-priming pump.
The utility model has the advantages that:
the structure is comparatively simple, easily makes, can guarantee that the automatic control self priming pump can both normally start at every turn, can shorten greatly and inhale the time from inhaling, and very suitable large-traffic automatic control self priming pump.
