Abstract
The utility model discloses an automatic shifting device with two water sources. The device comprises two water sources and a controller, pressure sensors are arranged inside the two water sources respectively and electrically connected with the signal input end of the controller, pipelines are connected with the two water sources respectively, water pumps are arranged in the pipelines, and the signal output end of the controller is electrically connected with the water pumps through electrically operated valves. The shifting device has the advantages of small size and integration, the water pressure of the two water sources can be detected automatically, fast automatic shifting of the two water sources can be achieved without a shutdown, the pressure of the two water sources cannot fluctuate, therefore water for users and industrial production are not affected, and the shifting device can be applied to important places such as urban water supply and industrial production.
Description
Technical field
The utility model relates to a kind of double water source automatic switching control equipment.
Background technology
Change in modern times in the construction, it is also increasingly high to quality of water supply and reliability requirement (to comprise life water, industrial water use) in city secondary water-supply and the commercial production, and traditional single channel way of supplying water can't satisfy present situation.And the water supply of two-way water source has obtained using widely in industry and civilian construction; But the two-way water source just can switch after when automaticallying switch, all being to shut down; Deng the water source switch finish after start operation again, the water source switches downtime minimum needs about 4 minutes, because the water source switching device need be shut down; To interrupt so supply water when shutting down, thereby influence is produced and the user supplies water.
The utility model content
The purpose of the utility model provides a kind of double water source automatic switching control equipment, realizes the online switching of double water source and does not cause equipment downtime.
The technical scheme of the utility model is following:
A kind of double water source automatic switching control equipment; Include two road water sources and controller; It is characterized in that: the inside at said two road water sources is respectively equipped with pressure sensor, and described pressure sensor is connected with the signal input part of controller, and described two road water sources are connected with pipeline respectively; In the described pipeline water pump is installed, the signal output part of said controller is electrically connected with the motor of water pump through electrically operated valve.
Described double water source automatic switching control equipment is characterized in that: described controller adopts PLC.
The beneficial effect of the utility model:
The utlity model has little, the integrated characteristics of volume; Can detect double water source hydraulic pressure automatically; Can realize that the two-way water source do not shut down quick automatic switching, and fluctuation can not appear in the pressure at two-way water source, thereby guarantee that user's water and commercial production are unaffected; Can be applicable to urban water supply, important place such as commercial production.
Description of drawings
Fig. 1 is the utility model circuit structure schematic diagram.
The specific embodiment
Referring to Fig. 1, a kind of double water source automatic switching control equipment includes two road water sources, is respectively equipped with P1 on the pipeline at two road water sources; P2 pressure sensor M1, the M2 motor operated valve, P1, the P2 pressure sensor detects pipeline pressure in real time; P1, P2 pressure sensor output signal is electrically connected with the analog quantity input of PLC, E1, the E2 valve positioner is connected with PLC control delivery outlet; E1, E2 valve positioner and M1, the M2 motor operated valve connects.Among water supply outlet conduit and double water source inlet duct, many water pumps are installed.
Below in conjunction with accompanying drawing the utility model is further described:
(1), pressure measxurement: the hydraulic pressure of two road water source P1, P2 is detected by pressure sensor and obtains, and is transported to PLC processing and analysis.
(2), not termination of pumping of double water source is switched:
Controller is in real time to P1, and P2 two-way water source hydraulic pressure carries out the lack of water prediction, and before any one tunnel lack of water 10s of double water source, controller can send lack of water early warning signal accurately, thereby commander water source by-pass valve control switches.
After water source P1 lack of water, PLC will send instruction, open electric valve controller E2; PLC detects the position of electrically operated valve M2 automatically; After confirming that electrically operated valve M2 opens, electric valve controller E1 can close the M1 motor operated valve automatically, and this moment, water pump can automatically switch under the non-stop-machine operating mode on alternate source P2, the M2 branch road; P1, M1 branch road close and stop to supply water.
After water source P2 lack of water, PLC will send instruction, open electric valve controller E1; PLC detects the position of electrically operated valve M1 automatically; After confirming that electrically operated valve M1 opens, electric valve controller E2 can close the M2 motor operated valve automatically, and this moment, water pump can automatically switch under the non-stop-machine operating mode on alternate source P1, the M1 branch road; P2, M2 branch road close and stop to supply water.
Claims (2)
