System safe operation.
Startup of the start-up and shut-down control method for controlling deep cooling pumping system shown in Fig. 2, therefore the start-up and shut-down control method shown in Fig. 2
It is referred to as the startup step sequence of deep cooling pumping system.
In one embodiment, the enabled condition of startup step sequence is：1. the pressure of sealing Nitrogen source gases is more than preset pressure value；
2. the liquid level in liquefied air storage tank 1 is more than preset height.That is, it is necessary to prejudge to cyropump before step 101 is carried out
It is pre- whether the liquid level whether pressure of the source of the gas of logical sealing nitrogen is more than in preset pressure value, and liquefied air storage tank 1 is more than
If height, in the case where above-mentioned two condition is all met, just allow deep cooling pumping system to start.Normally, above-mentioned default pressure
Force value is 0.2MPa, and preset height is 1m, i.e., when the pressure of sealing Nitrogen source gases is more than in 0.2MPa and liquefied air storage tank 1
Liquid level be higher than 1m when, it is allowed to deep cooling pumping system start.
The embodiment of the present invention also provides a kind of start-up and shut-down control method of deep cooling pumping system, the execution master of the start-up and shut-down control method
Body can be computer system or dcs.As shown in figure 3, the start-up and shut-down control method is mainly included the following steps that：
Step 201, judge whether the first cyropump 3 frequency converter frequency and the second cyropump 4 frequency converter frequency
It is down to predeterminated frequency.If the frequency converter frequency of the first cyropump 3 or the second cyropump 4 does not drop to above-mentioned predeterminated frequency, or
The frequency converter frequency of two cyropumps does not drop to above-mentioned predeterminated frequency, then carries out step 202, send the first cyropump 3
The frequency converter frequency of frequency converter frequency and the second cyropump 4 is down to the instruction of predeterminated frequency.If the frequency converter of the first cyropump 3
The frequency converter frequency of frequency and the second cyropump 4 is reduced to predeterminated frequency, carries out step 203.
In one embodiment, above-mentioned predeterminated frequency can be set to 15Hz, when closing deep cooling pumping system, first by two depths
The frequency converter working frequency of cold pump is reduced to 15Hz (containing) below, then cyropump out of service, can reduce deep cooling pumping system and stop
The impact produced when only.
Step 203, judge whether cyropump system outlet electrically operated gate 15 has closed.If cyropump system outlet electrically operated gate 15
Do not close, send the instruction (step 204) for closing cyropump system outlet electrically operated gate 15.If cyropump system outlet electrically operated gate 15
It has been closed that, carry out step 205.
Step 205, judge whether to have dropped out cyropump interlocking.If not exiting cyropump interlocking, send and exit cyropump
The instruction (step 206) of interlocking.If having dropped out cyropump interlocking, step 207 is carried out.
Step 207, judge whether the first cyropump 3 and the second cyropump 4 are out of service.If the first cyropump 3
It is not out of service, or the second cyropump 4 do not stop, or two cyropumps are not out of service, then send stopping first deep
The instruction (step 208) of the cold cyropump 4 of pump 3 and second operation.If two cyropumps are out of service, step 209 is carried out.
Step 209, the 1. entrance electrically operated gate 9 of the first cyropump 3 and outlet electrically operated gate 10, the second cyropump 4 are judged whether
Entrance electrically operated gate 11 and outlet electrically operated gate 12 closed, 2. and cyropump motorized recycling valve 6 and cyropump recycling regulation
Valve 7 has been closed.If two above condition has one not meet, or two conditions are unsatisfactory for, and are carried out step 210, are sent
Close the first deep cooling pump intake electrically operated gate 9 and outlet electrically operated gate 19, the second deep cooling pump intake electrically operated gate 11 and outlet electrically operated gate 12
Instruction, and close cyropump motorized recycling valve 6 and cyropump recycles the instruction of regulating valve 7.If above-mentioned two condition
All meet, carry out step 211.
Step 211, judge whether the drain valve 19 of the cyropump 4 of drain valve 18 and second of the first cyropump 3 has been opened.Such as
Really there is one not open in two drain valves or two drain valves are not opened, send the first cyropump drain valve of unlatching 18 and second deep
The instruction (step 212) of cold pump drain valve 19.
The purpose of step 211 and step 212 is to open the liquefied air that cyropump drain valve releases surplus, is prevented because of liquefaction
Atmosphere temperature rising causes cyropump to import and export pipeline pressure rising.

Start；Under cyropump system running state, being automatically stopped for deep cooling pumping system is realized；When the operation of cyropump startup procedure
To a certain step when, if condition is unsatisfactory for, but if artificially judging that the condition can ignore that, then can carry out manually leapfrog action after
The operation of continuous startup program, is finished until deep cooling pumping system starts.
Each step in start-up and shut-down control method shown in Fig. 2 and Fig. 3, all first judges whether feedback receives, if receiving feedback
Then continue next step；If not receiving feedback, command adapted thereto is sent, and wait to be feedback.Due feedback signal is not being received
When, programed logic can rest on the step, wait operative.Power plant operations staff can find current operation step sequence and not receive
The feedback signal arrived, artificially judges whether unreceived feedback signal influences continuing executing with for program programed logic.If should
Feedback signal does not influence proceeding for present procedure control logic, and operations staff can operate leapfrog action to continue programme-control
The execution of logic；If feedback signal influence present procedure control logic proceeds, operations staff can be according to finding
Each unsatisfied feedback signal, targetedly go investigation problem, until receive the feedback signal, continue executing with program
Control logic.
