Abstract

The utility model discloses a time-delay protection and control system for a water pump. The time-delay protection and control system comprises a controller, a water level control switch and a water flow switch, wherein the controller comprises a direct current relay and an alternating-current relay, the water level control switch is a time-delay switch and comprises two water level contacts arranged on a high water level and a low water level of a water tower, and the water flow switch comprises an inner switch cylinder with a slot and an outer switch cylinder. A horizontal shaft passes through the slot and is fixed on the outer switch cylinder, and the outer wall of the inner switch cylinder and the inner wall of the outer switch cylinder are each provided with a contact, and the water level control switch is in parallel connection with the water flow switch and in serial connection with the direct current relay. The alternating-current relay controls the operation of the water pump. The time-delay protection and control system controls the operation of the water pump through the water level control switch and the water flow switch, and is simple in structure. The time-delay protection and control system automatically controls the operation of the water pump, protects the water pump when a well is in water shortage and prevents idle running of the water pump.

Description

The delay protection control system of water pump

Technical field

The utility model relates to the delay protection control system of a kind of protection system of water pump, particularly water pump.

Background technology

Due to the current universal tap water in rural area, most of common people family is also being used well water, by water pump by underground water pump in the water tower on roof, then water pipe is delivered to the place that each needs water.Although the control system of present water pump can realize automatic pumping, there is following hidden danger: 1, the uncontrollable extraction time, cause the spill-over of water tower water to go out; 2, well lack of water or water pump fault, cause and take out not water outlet, thus the wasting phenomenons such as water pump idle running.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, can automatically controlled water pump work and in the time of well lack of water, water pump is protected, prevent the delay protection control system of the water pump of water pump idle running.

For realizing goal of the invention, the technical solution adopted in the utility model is: a kind of delay protection control system of water pump, it is characterized in that: comprise controller, level control switch for water, water flow switch, described controller includes a DC relay and an AC relay, level control switch for water is delay switch, includes 2 water level contacts that are arranged on water tower high water level and low water stage; Water flow switch includes switch inner core, switch urceolus, on switch inner core, have a groove, one horizontally disposed axle passes and is fixed on switch urceolus from groove, be respectively equipped with a contact at the outer wall of switch inner core and the inwall of switch urceolus, wherein after level control switch for water and water flow switch parallel connection, connect with DC relay again, the work of AC relay control water pump.

The utility model is by level control switch for water and water flow switch control pump working, simple in structure, can automatically controlled water pump work and in the time of well lack of water, water pump is protected, prevent that water pump idle running phenomenon from occurring.

Detailed description of the invention

Below in conjunction with accompanying drawing and concrete embodiment, the utility model is further elaborated.

From Fig. 1,2, the delay protection control system of the utility model water pump, comprise controller, level control switch for water, water flow switch, described controller includes a DC relay and an AC relay, level control switch for water is delay switch, includes 2 water level contacts that are arranged on water tower high water level and low water stage; Water flow switch includes switch inner core, switch urceolus, on switch inner core, have a groove, one horizontally disposed axle passes and is fixed on switch urceolus from groove, be respectively equipped with a contact at the outer wall of switch inner core and the inwall of switch urceolus, wherein after level control switch for water and water flow switch parallel connection, connect with DC relay again, the work of AC relay control water pump.

The course of work: in the time that water tower arrives low water stage, connect DC relay circuit by level control switch for water, AC relay is connected in DC relay work, water pump is started working, and under normal circumstances, the water of smoking passes through from water flow switch, switch inner core is risen to upper punch, connect water flow switch, level control switch for water time delay simultaneously finishes, and water pump is worked under water flow switch control; Can not take out at water pump under the abnormal conditions of water, owing to not having current to pass through from water flow switch, after level control switch for water time delay finishes, DC relay down circuitry, thus AC relay disconnects water pump circuit, prevents water pump idle running.

In the time that water tower level arrives high water level, close DC relay circuit by level control switch for water, DC relay power-off, thus AC relay also disconnects water pump circuit, and water pump quits work.

More than show and described general principle of the present utility model and principal character and advantage of the present utility model, the technician of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and manual, describes just illustrates principle of the present utility model, do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
