Abstract
The utility model relates to an automatic control device for a water pump of a water tower, which is used for automatic start and automatic stop for the water pump. The utility model comprises a bracket, a base, a pressure transmission mechanism, and a contact switch, wherein, the pedestal is fixed on the base, and the pressure transmission mechanism and the contact switch are arranged on the bracket; the contact switch is connected above the pressure transmission mechanism, and two floating cylinders are connected below the pressure transmission mechanism; the arranged positions of the two floating cylinders and the length of the two floating cylinders determine upper water level and lower water level which are controlled; a control source which change the work state of a switch is composed of the two floating cylinders. When the water level is controlled to a controlled position, a motor automatically starts or automatically stops. The utility model has the advantages of water saving and electricity saving.
Description
The utility model relates to a kind of water tower water pump automatic controller, and particularly a kind of water pump automatic controller of level sensing device up and down that adopts is used for starting automatically and switching off the pump.
The present most water towers of China, reservoir are all built on the house top, adopt the hand switch control of pump to draw water, and often will arrive water and overflow water tower and just know and switch off the pump.If the well limited from the water source draws water, taken out too much when water, can make water pump leave the water surface, not only cause waste, and can burn out motor.
The purpose of this utility model is a kind of water tower water pump automatic controller of design, adopts level sensing device up and down, thereby reaches the purpose of automatically controlled water pump.
Water tower water pump automatic controller includes support, base, pressure drive mechanism and contact switch, support is fixed on the base, pressure drive mechanism and contact switch are arranged on the support, the top of the pressure drive mechanism contact switch of ining succession, below two floating drums of ining succession, two position and controlled upper and lower water levels of length decision that floating drum is placed.Form switch working state conversion and control source by two floating drums, utilize its weight by connecting lead and pressure drive mechanism, under the effect of water level up and down, be used for the duty conversion of gauge tap.
The utility model is formed switch working state conversion and control source with two floating drums, when the energy control water level arrives by controlled position, starts automatically or the disable motor power supply, has the characteristics of using water wisely, electricity consumption.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structure cut-away view.
Among the figure: 1-outer cover, 2-compression spring, 3-power transmission pressing plate
4-fixedly brandreths 5-connection lead 6-terminal screw
7-normal opened contact, 8-movable contact, 9-normally closed contact
10-pressure pillar, 11-power transmission pinch roller, 12-base
13-support 14,15-floating drum 16,17-power transmission fulcrum
Present embodiment is arranged in the water tower, and when floating drum floated, switch was in normal opened contact.Pressure drive mechanism includes power transmission pressing plate 3, power transmission pinch roller 11, and floating drum 14,15 links to each other with power transmission pinch roller 11 by connecting lead 5.Contact switch is provided with compression spring 2 and pressure pillar 10, and pressure pillar 10 withstands power transmission pressing plate 3, and contact switch is provided with normal opened contact 7, normally closed contact 9 and movable contact 8, and movable contact 8 is fixed on the pressure pillar 10.
When two floating drums were all bubbled through the water column, connecting lead did not have pulling force, and power transmission pinch roller, power transmission pressing plate are in original state, and contact switch is on normal opened contact.When drawdown when floating drum 14 leaves the water surface, switch still is in original state.When drawdown when floating drum 15 leaves the water surface, the weight of two floating drums on the pressure pillar, makes contact switch be converted to normally closedly by often opening by power transmission pinch roller, power transmission pressing plate function, connects machine operation.When water level rose to floating drum 15 and floats, switch still was in normally closed contact.When water level rises to two floating drums 14,15 and all bubbles through the water column, at this moment there is not pulling force, switch promptly is converted to original state, and motor cuts out.
When controller is placed in the water tower, the original state of contact switch is in normal opened contact, and drawdown is during to water level down, and water pump draws water, and water level rises when reaching water level, and water pump stops.When controller is placed in the well that draws water, the original state of contact switch is in normally closed contact, and when water level rose to water level, water pump drew water, and drawdown is during to water level down, and water pump stops.Position and length that upper and lower water level is placed by two floating drums decide.
Claims (2)
1, a kind of water tower water pump automatic controller, include support, base, pressure drive mechanism and contact switch, support is fixed on the base, pressure drive mechanism and contact switch are arranged on the support, the top that the it is characterized in that pressure drive mechanism contact switch of ining succession, the position that below two floating drums of ining succession, two floating drums are placed determines controlled upper and lower water levels with length.
2, water tower water pump automatic controller according to claim 1, it is characterized in that being placed in the water tower when controller, the original state of contact switch is in normal opened contact, and when controller is placed in the well that draws water, the original state of contact switch is in normally closed contact.
