Background
Before starting, the centrifugal pump needs to be filled with liquid, namely, before starting, the liquid is filled into the pump and the suction pipe, and the water level exceeds the impeller. This is because the centrifugal pump is designed to generate a vacuum around the impeller by the centrifugal force generated by the rotation of the impeller, thereby generating a suction force to suck and throw out water. If the gas in the pump shell is more before starting, the centrifugal force generated is too small due to the small gas weight, so that water cannot be sucked up, and the centrifugal pump can idle. If the pump is not primed before start-up, or if the water inlet is short of water, idle running occurs. The mechanical seal or the packing seal of the centrifugal pump can not be lubricated due to long-time idling, the abrasion is serious, the pump body can gradually generate heat, partial gap can be bitten when the pump body is serious, and the performance and the service life of the pump are seriously influenced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1, an energy-saving water pump with water shortage protection function comprises a motor 1, a coupling 2, a pump shell 3, an impeller, a base 4, a water inlet 5, a water outlet 6, a pull rod 7 and a control cabinet 14; the motor 1 is connected with the control cabinet 14; a liquid level sensor 12 is arranged on the inner wall of the pump shell 3; the liquid level sensor 12 is positioned above the impeller; a first electromagnetic valve 11 is arranged on the water outlet 6; a second electromagnetic valve 15 is arranged on the water inlet 5; the inner wall of the upper part of the pump shell 3 is also provided with a vacuum degree sensor 10; the liquid level sensor 12, the first electromagnetic valve 11, the second electromagnetic valve 15 and the vacuum degree sensor 10 are all connected with the control cabinet 14.
Above-mentioned energy-conserving water pump with water shortage protect function detects through level sensor 12 whether the water in the pump case 3 covers the impeller, can real-time detection the vacuum in the pump case 3 through vacuum sensor 10 to convey the testing result to switch board 14, switch board 14 can be according to opening and close of testing result control motor 1, thereby avoids the pump body to take place the idle running.
Specifically, the motor 1 is provided with a current detection device 8; the current detection device 8 is connected to the control cabinet 14. When the water pump idles, the current is reduced, so that the current can be monitored to assist in judging the working state of the water pump.
