To achieve these goals, the technical solution of the utility model is: a kind of centrifugal pump vacuum water diversion starting drive is characterized in that: start jar, service water supply system, exhaust pipe and electric control box by vacuum pump, moisture trap, vacuum water-filling and form; Serve water supply system and communicate with the vacuum pump bottom, the vacuum pump top is equipped with moisture trap, and vacuum pump starts jar by exhaust pipe and vacuum water-filling and is communicated with, and vacuum water-filling starts jar and is connected with the public exhaust tube of centrifugal pump; Into water modulating valve, service water flow switch and moisturizing solenoid valve are installed on the water supply line of service water supply system successively; Vacuum water-filling starts on the jar is furnished with draining air inlet solenoid valve, vacuum gauge, liquid-level switch and drain solenoid valve; Be installed into gas isolating valve and safety check on the exhaust pipe.
Into water safety check, pressure gauge and bypass manually operated valve are housed on the water supply line of above-mentioned service water supply system.
Above-mentioned vacuum water-filling starts the interface that jar is provided with the vacuum pump pumping tube, and exhaust pipe is connected on this interface.
Above-mentioned vacuum water-filling starts jar and is provided with the interface that is connected with the public exhaust tube of centrifugal pump.
The utility model can make underground complete self filling type pumping plant build up ground type or semi-underground type pumping plant, reduces the pumping plant buried depth, saves civil engineering costs.This device can solve the automatic diversion startup problem of centrifugal pump when low water level in ground type or the semi-underground type pumping plant, realizes that the concentrated diversion of many pumps starts, and pumping plant one stepization is operation automatically, reaches unattended purpose.
Description of drawings:
Fig. 1 is the utility model embodiment's a system layout schematic representation.
Embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
A kind of centrifugal pump vacuum water diversion starting drive of the present utility model comprises that two vacuum pumps 1 (the using and the reserved), two moisture traps 2, a vacuum water-filling start jar 3, one groups of compositions such as service water supply system 4, exhaust pipe systems 5 and a cover electric control box 6.Vacuum water-filling starts is furnished with draining air inlet solenoid valve 7, vacuum gauge 8, liquid-level switch 9, drain solenoid valve 11, the interface 20 that connects the public exhaust tube of centrifugal pump and the interface 10 of vacuum pump pumping tube on the jar 3.Service water supply system 4 comprises into water modulating valve 14, water inlet safety check 15, service water flow switch 16 and pressure gauge 17, separate unit vacuum pump moisturizing solenoid valve 18 and bypass manually operated valve 19 etc.Exhaust pipe system 5 comprises the air inlet isolating valve 12 and the safety check 13 of every vacuum pump 1.
The utility model adopts full automation control, and electric control box has control knob and the indication of reporting to the police, but both execute-in-places is also remote controlled.Electric control box is accepted the instruction operation of pumping plant higher level control unit, and can be by the upwards level control unit conveying system operation of passive contact, stop and the malfunction alarm model, can realize that pumping station one stepization is automatic to operate.
The utility model is integrated compact design, except the Overflow drainage interface that leaves the drain solenoid valve interface that service water interface, water-filling with the pump-line interface of centrifugal pump, vacuum pump start jar, every vacuum pump gas water separation tank, have a complete system of one's own.Service water can adopt plant area's tap water of certain pressure, and Overflow drainage and water-filling start a jar draining and be connected to sewerage.When the service water supply system broke down, service water flow switch sent signal alarm.
Working procedure of the present utility model is as follows: all water pump top vent are all installed an electrically-controlled valve (solenoid valve or electric ball valve) in the pumping plant, and link to each other with public centrifugal pump pump-line and water-filling startup jar.On the water-filling startup jar automatic signal generator-high and low liquid-level switch is housed, vacuum pump system is according to its instruction work automatically.When the pumping station upper-position unit to this device electric control box send start certain centrifugal pump signal after, this system at first detects the liquid-level switch of water-filling on starting jar, if high level switch does not have closure, represents that this system is in holding state.At first, electrically-controlled valve is opened on certain the centrifugal pump top suction branch that needs to start, then, moisturizing solenoid valve on vacuum pump and the respective service water lines is opened simultaneously, air water mixed solution in the vacuum pump chamber is by moisture trap, and air is separated out, and divides dried up overflow discharging, simultaneously, water-filling starts a jar interior degree of vacuum rising.Under the situation that air has been arranged fully in that centrifugal pump shell, centrifugal pump internal pressure water enters water-filling along pump-line and starts in the jar, and jar middle water level rises, when in reaching jar, setting high water level, high level switch sends signal, and the vacuum water diversion pumping process is finished, and centrifugal pump can open pump; Then, vacuum pump stops, and service water entering water electromagnetic valve is closed simultaneously, then, draining air inlet solenoid valve and drain solenoid valve are opened simultaneously in the water-filling startup jar, and air enters and starts in the jar, starts a jar draining, when draining to jar in when setting low water level, low liquid-level switch sends signal, and draining is finished, and draining air inlet solenoid valve and drain solenoid valve are closed simultaneously, native system is in holding state again, waits for the vacuum water diversion start-up course of bleeding of next batch.
