Description
Technical field
The present invention relates to industry spot electrically, the additional protective cover of instrument or equipment, more particularly, to a kind of water-cooled protection
Cover and its control method.
Background technology
The electric, instrument that industry spot high temperature applicationss are run or equipment need additional protective cover.A kind of typical protective cover
Using water circulation cooling, protected object is arranged in protective cover, and protective cover enters the cooling with certain pressure from bottom
Water, top water outlet (ensureing to be full of water in protective cover), to ensure that protected object passes through cooling water and high temperature is isolated, such as one
The industrial camera determining high temperature applicationss use is all using this device.
There is cooling water and cut off the water supply fault in industry spot.If cooling water is cut off the water supply, the cooling water in protective cover will be along water inlet pipe
Road flows back, and due to cutting off the water supply in protective cover, temperature will be led to raise rapidly, and (speed that temperature raises just becomes with operating ambient temperature
Ambient temperature is higher, and programming rate is faster for ratio), and then lead to protected device temperature rise, cannot normally be transported by protection device
OK, or even protected device damage.
Generally, it is desirable to protected device is removed high temperature scene immediately after there is this fault in factory.
Look into and newly obtain, some expensive devices running at high temperature scene adopt machine automatization shift-out mechanism, for example
Thermal camera.Related shift-out mechanism needs specially to be designed according to site space, position.The protection device of other high temperature applicationss
After fault of cutting off the water supply, the method for taking manual demolition protective cover and equipment.
After cutting off the water supply, using automatically moving out device, not only mechanism is complicated, specificity is strong, and requires to increase investment and run
Maintenance cost；Take manually interim method for dismounting, increased work on the spot amount, some by protection equipment when installing again, also
Need to carry out adjustment.Once being run scene by protection device removal, control function originally can not reuse, and has a strong impact on work
Operation in skill flow process, supervision and control function.So far for this reason, factory is similar in device configuration, still lack and more effectively solve
The device of the problems referred to above and technical scheme.
Content of the invention
For correlative technology field document and above the deficiencies in the prior art, in a large amount of existing document researchs with for a long time in phase
On the basis of the Development Practice of pass field, the present invention proposes " a kind of water-cooled protective cover and its control method ", overcomes existing skill
In art, " using automatically moving out device, not only mechanism is complicated, specificity is strong, and requires to increase investment and operation and maintenance cost；Adopt
Take manually interim method for dismounting, increased work on the spot amount, some by protection equipment when installing again in addition it is also necessary to be adjusted
The technical barriers such as school ", realize the beneficial effect of " protective cover is not to move out live continuous service after cutting off the water supply ".
For achieving the above object, the present invention is achieved by the following technical solutions: a kind of water-cooled protective cover, including

2nd, for detecting the pressure-detecting device 1 of cooling water pressure on inlet channel, being used for detecting cooling water tank 4 outlet conduit flow
Flow detector 5 and for gathering pressure-detecting device 1 and the controller 7 of flow detector 5 signal, controller 7 is controlled
The switch of entering water electromagnetic valve 2 processed.It is attached by least two pipelines between described cooling water tank 4 and cooling guard shield 3.Described
Each pipeline section amasss 4/5ths that sum is more than the area of cooling guard shield 3 top surface.Described protective cover is additionally provided with aerofluxuss electromagnetism
Valve.
The volume of described cooling water tank 4 is customized according to the size of site environment temperature, protective cover.This protective cover described
Also include the alarm that is connected with controller and be arranged on the pressure transducer being provided with cooling water tank 4 for sensed water level.
A kind of control method of water-cooled protective cover, the method includes the steps of: step one, when cooling water normal water supply
In the case of, through pressure-detecting device 1 and entering water electromagnetic valve 2, to cooling guard shield 3 supply cooling water, cooling water is to upstream for water inlet
Cooled water tank 4 full of after cooling water tank 4, enters outlet conduit, circulating cooling, aerofluxuss electricity by flow detector 5
, under controller 7 logic control, place is in off position for magnet valve 6；Step 2, when pressure-detecting device 1 detect pressure be less than just
Often pressure of supply water or flow detector 5 have detected flow and be less than normal value, and controller 7 will be automatically brought into operation entering water electromagnetic valve 2 and close
Close；Exhaust solenoid valve 6 is opened, and enters the evaporation state of cooling.Step 3, when recover cooling water, by pressure-detecting device 1
It is higher than required value that pressure will be detected, and entering water electromagnetic valve 2 opened by controller 7, and through control logic time delay, whether detection flows are full
Foot requires, and when flow satisfaction requires, enters the normal water supply state of cooling, closes exhaust solenoid valve 6.When protective cover is in evaporation
During the state of cooling, the water of cooling water tank 4 storage passes through multiple pipelines and is directly connected to cooling guard shield 3, and constitutes hot-fluid upwards interior
Portion's cooling circulation, the steam of generation is discharged by exhaust solenoid valve 6.When protective cover is in the evaporation state of cooling, pressure
When sensor detects water level less than designated water level, controller controls alarm to be reported to the police.
The beneficial effect that the present invention is implemented is: ensure that and is continuously run at the scene by protection equipment；Decrease field apparatus
Configuration (automatically moving out) or troublesome poeration (after cutting off the water supply remove), decrease workload, the corresponding maintenance expense of the equipment that decreases
With；Guarantee protected object not by high temperature failure；This device may apply in other same type systems.Specific economic benefit
Technique field requirement according to this plant running is determined.
