Abstract
The utility model relates to an automatic pressure control immersible pump chooses for use a pressure relay as the switch of immersible pump, couples pressure cylinder and pressure relay, sets for pressure relay's starting pressure value and stop pressure value. When the pressure in the pressure bottle body reaches the upper limit pressure of the pressure relay, the relay is disconnected, and the water pump motor stops running; when the pressure in the pressure bottle body drops to the lower limit pressure of the pressure relay, the relay is closed, the water pump motor operates, namely, the device can control the automatic work of the water pump through the opening of the valve, and convenience is provided for the life of people.
Description
The utility model relates to a kind of water supply installation, particularly a kind of automatic pressure control submersible pump, and belonging to supplies water uses the submersible pump technical field.
Now in the water supply equipment field, most of submersible pump still relies on manual power switch to control its operation, method falls behind brings many inconvenience for worker, agricultural production and people's lives, developed the submersible pump of automatic control, but owing to adopt equipment such as heavy pressure water storage tank, air making-up air device, heavy so this system bulk is big, the cost costliness, functional reliability is poor.
The purpose of this utility model is to provide a kind of automatic pressure control submersible pump, and it has cancelled heavy pressure water storage tank and air making-up air device, and simple in structure, cost is lower, and functional reliability is strong.
Of the present utility model being contemplated that: select the power switch of a pressure relay for use as submersible pump, pressure bottle connects with pressure relay, the breakout pressure value of setting pressure relay and stop force value, when pressure bottle internal pressure reaches pressure relay upper limit pressure, relay disconnects, and pump motor shuts down, when pressure bottle internal pressure drops to the pressure relay threshold pression, the relay adhesive, pump motor running work.
Fig. 1 is the utility model structure principle chart.
Fig. 2 is the utility model one-way cock figure.
The utility model is by water pump (1); one-way cock (2); lifting pipe (3); conduit pipe (4); pressure bottle (5); pressure relay (6) and valve (7) etc. are formed (referring to Fig. 1); wherein pressure bottle (5) is a hollow container; on; an air inlet-outlet pipe is respectively arranged at the bottom; respectively with conduit pipe (4); pressure relay (6) connects; one-way cock (2) is by gland (8); rubber cushion (9); iron pad (10); spring (11); water intake (12); water outlet formations such as (13); rubber cushion (9); iron pad (10) is pressed on the water intake (12) by spring (11); if the elastic force of spring (11) is F; water intake (12) connects water pump (1); water outlet (13) and lifting pipe (3), conduit pipe (4), valve (7) forms water channel; on the contact of the motor switch pressing force relay (6) of water pump (1); after water pump (1) energising running, the water pump vane pumps water produces pressure, and the one-way cock pressurized is opened automatically and entered pipe network; this moment, ductwork pressure rose; the interior gas of pressure bottle (5) is compressed, and the body internal pressure rises, when rising to the CLV ceiling limit value of pressure relay (6) setting; pressure relay (6) action power dump; the water pump autostop, one-way cock (2) is subjected to anti-phase hydraulic pressure and closes, and has guaranteed the certain pressure of pressure bottle (5); after user's water is opened valve; ductwork pressure begins to descend gradually, and pressure bottle (5) internal pressure descends thereupon, when dropping to the lower limit of pressure relay (6) setting; power supply is connected in its contact adhesive, and water pump restarts work.
Pressure bottle mainly is balanced to regulate the stable pressure that triggers pressure relay, because the pressurized air in the pressure bottle, thereby can slow down head impact and impact of water hammer and influences the unnecessary startup that pressure relay causes because of pressure is out of control.
Characteristics of the present utility model are simple in structure, easy for installation, cost is lower, the devices such as the pressure water storing tank of complicated heaviness and air tonifying Qi have been saved, guaranteed that pump motor do not burn by reason ductwork pressure change and work, it has namely controlled the water pump automatic operation by the unlatching of valve feedwater, has reached the function of immersible pump self-priming, for worker, agricultural production and people's lives bring great convenience.
