Embodiment Construction

[0008] attached below figure 1 A water pump anti-idling protection device of the present invention will be described in detail below.

[0009] as attached figure 1 As shown, a water pump anti-idling protection device of the present invention is composed of a mechanical seal (1), a temperature sensor (2), a liquid flow meter (3), an AC contactor (4) and a single-chip microcomputer 5), and the mechanical seal ( 1) The temperature sensor (2) is connected to the single-chip microcomputer (5), and the liquid flow meter (3) and the AC contactor (4) are respectively connected to the single-chip microcomputer (5).

[0010] A water pump anti-idling protection device is mainly controlled according to the principle that the water pump idling time is too long to cause the machine seal to heat up. The temperature sensor is attached to the outside of the machine seal. When the liquid flowmeter detects that the water flow is insufficient, the single-chip microcomputer starts the temperature...

Abstract

The invention provides a water pump anti-idling protecting device which is composed of a mechanical seal, a temperature sensor, a fluid flowmeter, an alternating current contactor and a single chip microcomputer. The water pump anti-idling protecting device is characterized in that the mechanical seal is connected with the single chip microcomputer through the temperature sensor, and the fluid flowmeter and the alternating current contactor are connected with the single chip microcomputer. The water pump anti-idling protecting device has the beneficial effects that the device is automatically started when a water pump operates; when the water pump idles, is delayed and meets shutdown protecting conditions, the device stops operation of the water pump, and the purpose of shutdown protection after long-time idling is realized.

Description

technical field [0001] The invention relates to a protection device, in particular to a water pump anti-idling protection device. Background technique [0002] At present, most water pumps in the society are not designed with anti-idling protection function, but it is inevitable to encounter pumping out during the operation of the water pump. If the idling time is long, the service life of the water pump will be seriously affected. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a water pump anti-idling protection device. The device starts automatically when the water pump is running. To achieve the purpose of long-term idling shutdown protection. [0004] The technical solution adopted by the present invention to solve the technical problem is: a water pump anti-idling protection device is composed of a mechanical seal, a temperature sensor, a liquid flow meter, an AC contactor and a single-c...
