Description

WATER DRIVER

The utility model relates to the field of water supply, namely to the mechanization and automation of reckless water-lifting installations for individual residential and small public buildings.

Known water-lifting installation containing a pump, capacity

for water, suction and pressure pipelines, as well as sensors, -level and safety valve, while the tank is made with deformable walls and is equipped with a load mounted on the tank (description of the image to A. S. USSR N0632803. from 11/15/78, Bulletin No42).

The disadvantage of this installation is the complexity of its manufacture and lack of reliability in operation.

The purpose of the proposed utility model is to create a reliable water reservoir while maintaining a constant excess water pressure and eliminating water hammer in the water supply network.

The specified goal is achieved by that. what's in the water reservoir. containing a pump with a non-return valve, a water tank with an outlet pipe, a suction and pressure pipelines, as well as water and pressure level sensors and a safety valve, a control unit connected to water and pressure level sensors and with a pump control input is introduced into the suction pipe a water pressure and pressure sensor connected to the control unit is introduced, and a safety valve is connected between the suction and pressure pipes.

In addition, the water reservoir is equipped with a sump made in the lower part of the casing and containing a discharge pipe and a lid with a magnet.

IPC. - E 03

The water reservoir includes a pump 1 with a check valve 2, a water tank 3 with an outlet pipe 4, a suction 5 and a pressure 6 pipes, water level and pressure sensors 8. a pressure relief valve 9 connected between the suction 5 and pressure 6 pipelines, the control unit 10 connected with water level sensors 7 and pressure 8 and with a control input of the pump 1, as well as a sensor for the presence and pressure of water 11 installed in the suction pipe 5 and connected to the control unit 10.

In addition, the water reservoir is equipped with a sump 12, made in the lower part of the tank 3 and containing a drain pipe 13 and a cover 14 with a magnet 15.

The water reservoir works as follows.

The first case. The suction pipe 5 is connected to a centralized, for example, urban water main. When the pressure in the line exceeds a predetermined value of PO, the signal about its shutdown is sent to the pump 1 from the sensor for the presence and pressure of water 11 through the control unit 10 and the water under pressure through the check valve 2 enters the Water Storage. When the air pressure in the upper part of the water reservoir exceeds a predetermined value Ppr, the safety valve 9 is turned on between the suction 5 and pressure 6 pipelines. When the water flow and lowering its level, the air pressure in the upper part of the water reservoir and pressure pipe 6 decreases accordingly, the safety valve 9 closes and the water again enters the Water reservoir.

If the water pressure in the line is within 1 atm. to RO. from the sensor of the presence and pressure of water 11 through the control unit 10 to the pump 1 receives a signal about its inclusion and water under pressure through the check valve 2 enters the water reservoir. t When the air pressure in the upper part of the water reservoir exceeds the specified value of Rpr. as described above, the safety valve 9 is activated between the suction 5 and pressure 6 pipelines. In addition, when the air pressure in the upper part of the water reservoir reaches a predetermined value less than or equal to PPR, the signal 1 switches off from the water level sensors 7 and pressure 8 through the control unit 10 to the pump 1. When the water flow and lowering its level and correspondingly decreasing air pressure in the upper part of the water reservoir from the water level sensors 7 and pressure 8 through the control unit 10 to the pump 1 receives a signal about its inclusion. At a pressure of water from 0 to 1 atm. from the sensor And through the control unit 10 to the pump 1 receives a signal about its shutdown. The second case. Water is taken from an autonomous source, for example, from a well or well. The sensor 11 is turned off, and the pump 1 is controlled from the water level sensors 7 and pressure 8 through the control unit 10.
