Description
Technical field
This utility model relates to a kind of condenser vacuum constac in vacuum manostat field, especially design.
Background technology
At present, for power plant, suction condenser vacuum uses water jet air ejector or directly uses vacuum pump, but water jet air ejector is when evacuation, need uninterruptedly to be operated, if water jet air ejector or miscellaneous part break down, whole condenser vacuum will quit work, and staff overhauls, causing time lengthening, the equipment that affects normally works；Vacuum pump is directly used to carry out bleeding power consumption, vacuum stability is poor, because in the range of vacuum to ensure to maintain one, the higher limit such as setting vacuum system is set as-0.093MPa, lower limit is set as-0.09MPa, if vacuum is less than limit value-0.09MPa, equipment arises that exception.
Utility model content
During in order to solve existing water jet air ejector or directly use vacuum pump to bleed, it is impossible to the problem of normal work, a kind of vacuum stability is proposed good, when breaking down, the condenser vacuum constac that the equipment that still can ensure that normally uses.
The technical solution adopted in the utility model is as follows:
Condenser vacuum constac, including condenser, the air vent of condenser is connected by check-valves with the air inlet of vacuum accumulator tank, the gas outlet of vacuum accumulator tank is provided with pipeline, pipeline is respectively by arm parallel connection vacuum pump, cooler is in parallel with the air vent of each vacuum pump by pipeline, and described vacuum pump is connected with the water supplement port of cooler by water pipe；Described pipeline is provided with hand-operated valve and check-valves, and described arm is provided with hand-operated valve and check-valves；Described arm is flexible coupling with vacuum pump.
Further, in the check-valves of described vacuum accumulator tank is located at tank body or outside tank body.
Further, described vacuum pump is provided with gas vent.
Further, described water pipe is provided with water intaking valve.
Further, manostat is additionally provided with distribution box.
Further, vacuum accumulator tank is provided with electrode points vacuum meter.
Further, cooler is provided with air vent, overfall and liquidometer.
This utility model has the advantages that
This utility model is combined by vacuum accumulator tank and two vacuum pumps, ensure during condenser evacuation stable, when equipment runs into fault, another vacuum pump can be used to bleed, when changing with the vacuum pump check-valves of closing fault and hand-operated valve, in vacuum accumulator tank, vacuum ensure that vacustat is in a value range, not interfering with equipment work, then faulty component can be keeped in repair by we, and then will not delay machine operation.
This utility model ensure that condenser vacuum automatic voltage regulation, and simple in construction, and connection management is convenient, uses vacuum pipeline vacuum, is also convenient for during equipment fault steadily switching.
Accompanying drawing explanation
Fig. 1 this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
As shown in Figure 1, condenser vacuum constac, including condenser, the air vent of condenser is connected by check-valves 3 with the air inlet 2 of vacuum accumulator tank 1, the QI KOU 4 of vacuum accumulator tank 1 is provided with pipeline 6, pipeline is respectively by arm 8 parallel connection vacuum pump 9, and cooler 19 is in parallel with the air vent of each vacuum pump by pipeline, and described vacuum pump 9 is connected with the water supplement port 12 of cooler by water pipe 17；Described pipeline is provided with hand-operated valve 5 and check-valves 3, and described arm is provided with hand-operated valve 5 and check-valves 3；Described arm 8 and vacuum pump 9 are flexible coupling 7；In the check-valves 3 of described vacuum accumulator tank 1 is located at tank body or outside tank body；Described vacuum pump is provided with gas vent 10；Described water pipe 17 is provided with water intaking valve 11；Manostat is additionally provided with distribution box 16；Vacuum accumulator tank 1 is provided with electrode points vacuum meter 18；Cooler 19 is provided with air vent 14, overfall 13 and liquidometer 15.
nullWhen generating set opens machine condenser evacuation，First vacuum pump 9 is started，Knob is threaded to automatically，Wherein a vacuum pump 9 is started working，When in vacuum energy storage tank 1, vacuum reaches (-0.092MPa) value，(such as higher limit is set as-0.093MPa now to need to set on a display screen the upper lower limit value of vacuum system，Lower limit is set as-0.09MPa)，This system is properly functioning，On vacuum accumulator tank 1, the vacuum of electrode points vacuum meter 18 is for running vacuum，It is brought down below below lower limit-0.09MPa as run vacuum，Fault alarm will give a warning，PLC instruction stops fault vacuum pump，Vacuum system line shut by check-valves 3，Distribution box 16 instruction switching starts another vacuum pump，Keep vacuum system properly functioning，Needing maintainer checks another vacuum pump failure.Vacuum manostat runs automatically, makes vacuum accumulator tank 1 vacuum remain that setting value is run.As during Generation Unit Condenser evacuation, rate of air sucked in required is bigger, vacuum in vacuum accumulator tank 1 is evacuated to during setting value slow by separate unit vacuum pump, time was more than 15 minutes, instruction starts another vacuum pump, when vacuum is rapidly achieved setting value, instruction disables another vacuum pump automatically, maintains this system properly functioning.
The above; being only detailed description of the invention of the present utility model, but the protection domain of utility model is not limited thereto, any those of ordinary skill in the art are in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within the protection domain of utility model.
