System.In addition, the utility model production is simple, and it is at low cost, it is worthy of popularization.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
The utility model preferred embodiment is provided, with reference to the accompanying drawing the technical solution of the utility model is described in detail.
Fig. 1 is the overall structure diagram of the utility model, and it is automatic to provide injection vacuum for the utility model as shown in Figure 1:
Priming device includes: centrifugal pump 1, injector 7, solenoid valve 8, vacuum tank 4, liquid-level switch 5, integrated control case 6；Vacuum tank 4 is pacified
On the inlet duct 3 of centrifugal pump 1, liquid-level switch 5 is installed at the top of vacuum tank 4, injector 7 is connected to vacuum by pipeline
The top of tank 4 is equipped with solenoid valve 8 in the compressed air or liquid line 9 of the entrance of injector 7, there is one at the top of centrifugal pump 1
Pipe 2 is connected to vacuum tank 4, and injector 7 and solenoid valve 8 are mounted on inside integrated control case 6, injection vacuum automatic water diversion device
Part is automatically controlled to be controlled with integrated control case 6.
The injector 7 of the utility model is the injector of compressed air or liquid driven, compressed air or liquid driven
Injector 7, the device generated as vacuum.In the specific implementation process, the injector 7 of the utility model connects vacuum tank 4
Top and bottom of the pipeline apart from vacuum tank 4 distance range are as follows: 1:3-6.
The branch pipe 2 at 1 top of centrifugal pump is connected to vacuum tank 4, is centrifuged in pump operation, the gas of spilling can be discharged at any time,
Guarantee centrifugal pump stable operation.
Before centrifugal pump 1 prepares starting, vacuum automatic water diversion device will first start.When the liquid level of vacuum tank 4 reaches low liquid
When bit switch position, signal enabling centrifugal pump is issued by liquid-level switch.If having gas generation in the operation of centrifugal pump, due to true
It is negative pressure in slack tank, gas will be drawn onto vacuum tank by branch pipe 2.If the liquid level of vacuum tank reaches high level switch position
When, solenoid valve 8 is closed, that is, closes injection vacuum water diversion device.
In centrifugal pump normal use, if the liquid level of vacuum tank is lower than low liquid level, solenoid valve will be opened, and be started
It vacuumizes, hangs water function to realize, when the liquid level of vacuum tank reaches high liquid level, solenoid valve is closed, i.e. closing diversion dress
It sets.
When automatic closing system circuit start (additional control), after the preset time exceeds, centrifugal pump and
Priming device will turn off.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention, the utility model
Claimed range is defined by the appending claims and its equivalent thereof.
