Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
The embodiment is as follows:
referring to fig. 1-2, the present invention provides a medium lifting device for automatic drainage of a water pump, which comprises a pressurizing device 2 for pressurizing the lower part of a water pump 1 under the water pump 1 and a control device for controlling the operation of the water pump 1 and the pressurizing device 2, wherein:
the water pump 1 is higher than the liquid level of the pool, and the water pump 1 can normally run only after the pump cavity of the water pump 1 is filled with liquid medium;
the water pump 1 comprises a pump body and a water suction pipe connected with the pump body, the pressurizing device 2 comprises an air pump 21 and a water storage part 22, the air pump 21 is communicated with the water storage part 22, the water storage part 22 is arranged at the lower end of the water pump 1, namely at the lower end of the water suction pipe, and a one-way valve 23 is also arranged on the water storage part 22;
the one-way valve 23 is normally open, when the interior of the water storage part 22 is pressed, the one-way valve 23 is closed, namely, no spring is arranged in the one-way valve, and the sealing effect is achieved by the pressure difference between the water storage part 22 and the external medium of the water storage part 22; the check valve 23 is horizontally arranged on the water storage part 22, so that the check valve is not easy to catch dirt and is not closed tightly, and in addition, because the technical scheme is to utilize high-speed airflow to deduce the quick lifting of the water flow, even if the check valve 23 has a certain leakage problem, the normal operation of the device cannot be influenced.
As a preferred scheme, further, the control device comprises a control box 3, and an exhaust valve and a liquid level sensor which are arranged on an outlet of the water pump 1, wherein the control box 3 is electrically connected with the exhaust valve, the liquid level sensor, the air pump and the water pump;
the control box 3 enables the air pump 21 to be powered on, when the liquid level sensor detects that the liquid level exists, the control box 3 enables the air pump 21 and the exhaust valve to be powered off, and meanwhile, the water pump 1 is powered on;
if the exhaust valve is normally closed, the exhaust valve and the air pump 21 operate simultaneously, namely, when the air pump 21 works, the exhaust valve is powered on and opened;
if the exhaust valve is normally open, the exhaust valve and the water pump 1 operate simultaneously, namely when the water pump 1 works, the exhaust valve is powered on and opened;
in order to avoid dust entering the pump cavity of the water pump 1 from the exhaust valve when the device is in a standing state, the exhaust valve is in a normally closed type in the embodiment.
The working principle is as follows: after pressing the start button on control box 3, air pump 21, discharge valve and level sensor circular telegram work simultaneously, air pump 21 operation back high-pressure gas is along the upper portion of quick transport water storage portion 22, pressure rise in the water storage portion 22, the check valve is in the closed condition because of inside and outside pressure differential's reason, liquid medium in the water storage portion 22 enters into water pump 1 fast, discharge valve is normal close formula solenoid valve, be in the on-state when the work of getting to the electricity, pump intracavity and air are discharged by discharge valve fast, when the medium reachs level sensor, level sensor gives control box 3 signals, 3 control air pump 21 of control box control and discharge valve are closed simultaneously, the operation of simultaneous control water pump 1, because the pump intracavity has been filled with the medium this moment, so water pump 1 gets into normal operating condition.
