Description
Technical field
The present invention relates to industry spot electrically, the additional protective cover of instrument or equipment, particularly relate to a kind of water-cooled protective cover and control method thereof.
Background technology
Electric, the instrument that industry spot high temperature occasion is run or equipment need additional protective cover.A kind of typical protective cover adopts water circulation cooling; protected object is arranged in protective cover; protective cover enters with the chilled water of certain pressure, top water outlet (ensureing to be full of water in protective cover) from bottom; to ensure that protected object is by chilled water and high temperature isolation, the industrial camera such as used in certain high temperature occasion all adopts this device.
There is chilled water protect from water break in industry spot.If chilled water is cut off the water supply; chilled water in protective cover will reflux along inlet channel; owing to cutting off the water supply in protective cover; by cause temperature raise rapidly (temperature raise speed and operating ambient temperature be directly proportional; environment temperature is higher, and programming rate is faster), and then cause protected device temperature rise; protected device cannot normally run, even protected device damage.
Generally, after this fault occurs in factory, require protected device to shift out high temperature scene immediately.
Look into and newly obtain, some expensive device run at high temperature scene adopts machine automatization shift-out mechanism, such as thermal camera.Relevant shift-out mechanism needs according to site space, position specialized designs.The protective device of other high temperature occasion, after generation protect from water break, takes the method for manual demolition protective cover and equipment.
After cutting off the water supply, adopt automatic moving-out device, not only mechanism's complexity, specificity are by force, and require to increase investment and operation and maintenance cost; Take artificial interim method for dismounting, add work on the spot amount, some protected equipment, when again installing, also needs to carry out adjustment.Once protected device shifts out the scene of operation, monitoring function originally can not re-use, and have a strong impact on the operation in technological process, monitoring and controlling function.So far for this reason, factory class, like in Equipments Setting, still lacks the device and technical scheme that more effectively solve the problem.
Summary of the invention
For correlative technology field document and above the deficiencies in the prior art, in a large amount of existing literature research with for a long time on the basis of association area Development Practice, the present invention proposes " a kind of water-cooled protective cover and control method thereof ", to overcome in prior art " adopt automatic moving-out device; not only mechanism is complicated, specificity is strong, and requires to increase investment and operation and maintenance cost; Take artificial interim method for dismounting, add work on the spot amount, some protected equipment, when again installing, also needs to carry out adjustment " etc. technical barrier, realize the beneficial effect of " protective cover does not shift out on-the-spot 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; comprise cooling water tank 4 and cool cap 3; cooling water tank 4 is arranged on the top of cool cap 3; this protective cover also comprise entering water electromagnetic valve 2, for detect the cooling water pressure on inlet channel pressure-detecting device 1, for detecting the flow detector 5 of cooling water tank 4 outlet conduit flow and the controller 7 for gathering pressure-detecting device 1 and flow detector 5 signal, controller 7 controls the switch of entering water electromagnetic valve 2.Connected by least two pipelines between described cooling water tank 4 and cool cap 3.Each pipeline section described amass that sum is greater than the area of cool cap 3 end face 4/5ths.Described protective cover is also provided with exhaust solenoid valve.
The volume of described cooling water tank 4 customizes according to the size of site environment temperature, protective cover.This protective cover described also comprises the alarm that is connected with controller and is arranged in cooling water tank 4 pressure transducer be provided with for sensed water level.
A kind of control method of water-cooled protective cover, the method includes the steps of: step one, when in chilled water normal water supply situation, water inlet is through pressure-detecting device 1 and entering water electromagnetic valve 2, chilled water is supplied to cool cap 3, chilled water upwards flows through cooling water tank 4 and after being full of cooling water tank 4, enters outlet conduit, circulating cooling by flow detector 5, exhaust solenoid valve 6, under controller 7 logic control, is in closed condition; Step 2, when pressure-detecting device 1 detects that pressure have detected flow lower than normal value lower than normal water supply pressure or flow detector 5, automatic operation entering water electromagnetic valve 2 is closed by controller 7; Exhaust solenoid valve 6 is opened, and enters evaporative cooling state.Step 3, when recovery cooling water, to detect that pressure is higher than required value by pressure-detecting device 1, entering water electromagnetic valve 2 opened by controller 7, through steering logic time delay, detect flow whether to meet the demands, when flow meets the demands, enter the normal water supply state of cooling, close exhaust solenoid valve 6.When protective cover is in evaporative cooling state, the water that cooling water tank 4 stores directly connects cool cap 3 by multiple pipeline, and forms hot-fluid internal cooling circulation upwards, and the hot gas of generation is discharged by exhaust solenoid valve 6.When protective cover is in evaporative cooling state, when pressure transducer detects water level lower than designated water level, controller controls alarm and reports to the police.
Beneficial effect of the invention process is: ensure that protected equipment runs continuously at the scene; Decrease configuration (automatically shifting out) or the troublesome poeration (removing after cutting off the water supply) of field apparatus, decrease workload, the corresponding maintenance cost of the equipment that decreases; Guarantee protected object not by high temperature failure; This device can be applied in other system of the same type.Technique field requirement according to this plant running determines by concrete economic benefit.
