Automatic start and stop of the centrifugal pump is achieved.
Description
Technical field
The utility model relates to a kind of centrifugal water pump and automatically starts the start and stop sub controlling unit, and specifically a kind of centrifugal water pump automatic start-stop suction automatic controller solves the vacuum pumping device manual operation and makes centrifugal water pump can not realize the problem of automatic start-stop.
Background technique
The centrifugal water pump of some water source processing station is because the low in addition back with water inlet line of water inlet pressure head is long and the setting of control valve and filter at present, increased the hydraulic loss of pipeline, do not reach the requirement of centrifugal water pump suction lift, water can not be full of water pump cover before starting, enter some air, make water pump not reach the discharge lift after the startup, when air is many, often make water pump be in evacuated, for satisfying the operating conditions of centrifugal water pump, increased the vacuum pumping device of centrifugal water pump, because present vacuum pumping device all is manual operation, programmed sequence of operations is also cumbersome, makes the centrifugal water pump start and stop not realize automatic control and telecontrol.
Summary of the invention
The purpose of this utility model provides a kind of centrifugal water pump automatic start-stop suction automatic controller, overcomes the defective that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises centrifugal water pump, remote control magnetic valve, the on line control solenoid valve, the electric contact pressure vacuum gauge, vacuum pump, centrifugal water pump automatic controller and vacuum pump automatic controller, it is characterized in that: the vacuumizing joint on centrifugal water pump housing top is installed a remote control magnetic valve, the front of remote control magnetic valve connects an electric contact pressure vacuum gauge by connecting tube, an on line control solenoid valve is installed by connecting tube in front at the electric contact pressure vacuum gauge, the on line control solenoid valve is connected with the suction mouth of vacuum pump by connecting tube, and vacuum pump outlet is connected with liquid tank or directly enters sewerage; An electronic dish valve is installed in the centrifugal water pump outlet port; The lower limit signal output interface of electric contact pressure vacuum gauge automatically starts interface by vacuum pump automatic controller and on line control solenoid valve unlock interface, electronic dish valve and vacuum pump and is connected in parallel, the electronic dish valve unlock interface of the down interface of the startup interface on line control solenoid valve of the upper limit output interface of electric contact pressure vacuum gauge and the auto-starter of centrifugal water pump and centrifugal water pump outlet is connected in parallel, and has solved centrifugal water pump automatic start-stop problem.

Embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises centrifugal water pump 2, remote control magnetic valve 3, on line control solenoid valve 5, electric contact pressure vacuum gauge 4, vacuum pump 6, centrifugal water pump automatic controller and controller for vacuum pump, it is characterized in that: the vacuumizing joint on centrifugal water pump 2 housing tops is installed a remote control magnetic valve 3, the front of remote control magnetic valve 3 connects an electric contact pressure vacuum gauge 4 by connecting tube, an on line control solenoid valve 5 is installed by connecting tube in front at electric contact pressure vacuum gauge 4, on line control solenoid valve 5 is connected with the suction mouth of vacuum pump 6 by connecting tube, and vacuum pump outlet is connected with liquid tank or directly enters sewerage; An electronic dish valve 1 is installed in centrifugal water pump 2 outlet ports, the lower limit signal output interface of electric contact pressure vacuum gauge 4 automatically starts interface by vacuum pump automatic controller and on line control solenoid valve unlock interface, electronic dish valve down interface and vacuum pump and is connected in parallel, and the electronic dish valve unlock interface of the startup interface of the upper limit output interface of electric contact pressure vacuum gauge 4 and the auto-starter of centrifugal water pump 2, the down interface of on line control solenoid valve 5 and centrifugal water pump outlet is connected in parallel.
Take the centrifugal water pump model as OMEGA250-480A, flow is 1044 cubes m/hs, lift is that 70 meters online application automatic start-stop is example, because of many centrifugal pumps of pump room installation, at ordinary times operation only needs one or two, stand by pump when several centrifugal pumps are regularly switched use or conduct maintenance centrifugal water pump, remote control magnetic valve 3 on the centrifugal water pump housing for subsequent use on the vacuum-pumping tube is closing, the vacuum pressure that does not show centrifugal water pump on the electric contact pressure vacuum gauge 4, the automatic start-stop control of centrifugal water pump 2 and vacuum pump 6 is inoperative, does not have the problem of random start and stop.When determining to start certain centrifugal water pump, at first open certain remote control magnetic valve 3 on the centrifugal water pump vacuum-pumping tube with remote controller, electric contact pressure vacuum gauge 4 shows the vacuum pressure of certain centrifugal water pump immediately, when vacuum pressure≤-during 0.01Mpa, the lower limit interface of electric contact pressure vacuum gauge 4 is to vacuum pump automatic controller and 5 one actuating signals of on line control solenoid valve, on line control solenoid valve 5 is opened, vacuum pump starts, begin to vacuumize to centrifugal water pump, when vacuum pressure reach≤-during 0.04Mpa, the upper limit interface of electric contact pressure vacuum gauge is to vacuum pump and on line control solenoid valve 5 and 3 one shutdown signals of remote control magnetic valve, receive transmitter because being provided with signal in the vacuum pump automatic controller, remote control magnetic valve and vacuum pump 6 are closed, give simultaneously unlatching centrifugal water pump of automatic controller of centrifugal water pump 2 and the signal of the electronic dish valve 1 that the unlatching centrifugal water pump exports, centrifugal water pump starts, electronic dish valve is opened, centrifugal water pump 2 normal operation inputs, if stop centrifugal water pump, click stop button and get final product.
