Currently, domestic centrifugal chiller pumping plant mostly uses vacuumizing and exhausting to fill this law starting unit, it is small-sized or provisional poly-
It stands using method starting unit is manually controlled, large pumping station carries out unit starting and operation using automatic control method.It is general most
System station installs the starting method of vacuum water diversion controller and the linkage of unit main motor control switch additional using vacuum line.
The big religion structure of vacuum water diversion controller is tongue tube contact built in metal tube and magnetic buoy, when aggressiveness and pipeline
In the presence of inside having gas, buoy is not moved at this time, and tongue tube inner contact is in normally open.It is empty full of water in body and pipeline when attacking
After gas is discharged, water-filling in vacuum water diversion controller, buoy floats at this time, and tongue tube normal opened contact closure issues starting-up signal,
Start host groups.
Vacuum critical point diversion controller malfunction is vacuum formed rear tripping problem: facing due to being up to vacuum in water system
When boundary's point, the air-water mixture in pipeline enters vacuum water diversion controller, holds up internal float, connects diversion contact, sending is opened
Machine signal connects host groups booting circuit into face, causes host groups error starting in the case where partial vacuum, water pump cannot go out
Water, Auto Power On failure；Since vacuum water diversion controller uses overlong time, the blocking of internal corrosion sundries causes its internal float
Drift cannot float, and being vacuum formed rear diversion contact cannot be closed, and cause cannot be started up.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of intelligent vacuum diversion controller proposed by the present invention, master of the present invention
It is used to solve existing since vacuum water diversion controller is using overlong time, internal corrosion sundries blocking, causes its internal buoy
It cannot float, being vacuum formed rear diversion contact cannot be closed, and cause cannot be started up.
The technical solution adopted by the present invention to solve the technical problems is: a kind of intelligent vacuum diversion of the present invention

Granulated aggregate after abrasion can drop into the bottom end of vacuum water tank by filter mesh 81, can effectively reduce small-sized
The phenomenon that grain aggregate blocks in filter mesh 81.
As shown in Figure 1-Figure 3, it is provided with buffering in the base end wall of the screen pack 8 and squeezes cavity plate 19, and buffers and squeezes
The end of pressure cavity plate 19 is located at the underface of filter mesh 81；The base end wall that the buffering squeezes cavity plate 19, which is located at, floats
The surface of drift 13, and buffer extruding cavity plate 19 and be connected to by air slot 82 with extrusion chamber 181；When work, when floating buoy
13, when the impact of water flow is generated and floated up and down in the lower section of screen pack 8, can squeeze buffering and squeeze cavity plate 19, and then be arranged
Buffering squeeze cavity plate 19 can play the role of buffering to floating buoy 13, prevent floating buoy 13 in the impact of ripples in mistake
The phenomenon that upper generation abrasion of sieve plate 8；When buffering, which squeezes cavity plate 19, generates extruding, internal gas can pass through air slot
82 enter in extrusion chamber 181, and then scrotiform crushing block 18 is made to generate expansion, and then increase scrotiform crushing block 18 to small particle
The friction effect of aggregate；The phenomenon that scrotiform crushing block 18 after expanding simultaneously can make the top of filter mesh 81 generate jet, into
Enter to make to snap onto the granulated aggregate at smooth surface arc plate 11 and filter mesh 81 is quickly discharged under the promotion of gas, further increased
Filter effect of the sieve plate 8 to granulated aggregate.
Specific workflow is as follows:
When work, upon power-up, the solenoid valve 7 on drinking-water pipe 5 obtains electric-opening, and the solenoid valve 7 on drainpipe 6 is closed；Together
The working power of Shi Yinshui contact controller 10 is simultaneously switched on, and is started to work, as vacuum water tank 1 is pumped into very by vacuum pump 2
The continuation of null process, the air in water pump 4 are constantly excluded, and when starting water-filling in water pump 4, it is critical to progressively reach vacuum
Point flows through a certain amount of steam water interface in vacuum water tank 1, and the measurement resistance of electrode sensor is cooled down, detection device output
Voltage, internal delay units start timing, and the voltage signal in timing range is shielded, and microprocessing unit will not issue any letter
Number, internal and electric appliance is failure to actuate, and each contact is in original state, effectively escapes the steam water interface in vacuum water tank 1；When
When medium is flowed by screen pack 8, the heat on heating element R will be pulled away, and temperature reduces；Two thermistor R1
Variation with R2 voltage can be such that the voltage of B, C on measuring bridge also changes immediately；The variation of voltage indicates the variation of real-time flow rate；
As velocity of medium increases, heat loss increases, and maximum signal levels off to 1, if reaching the value, system saturation, then more
Thermal loss will not be detected, and when the voltage detected is more than the setting value of delay unit, microprocessing unit issues instruction,
Certain voltage is exported, the actuating of relay is driven, by the contact of relay, starting-up signal is issued, connects the automatic of host groups
Be switched on circuit, unit starting, and water pump 4 is discharged.
In the description of the present invention, it is to be understood that, term " center ", "front", "rear", "vertical", "horizontal",
