Set up wall monomer work pressure test platform, generally set up 150-300m according to cooling wall supply of material speed
2The trench drain is established in steel platform or the sand horsestone place through rolling around the place, and selects the water source.Establishing electronic box on the pressure testing platform.
The cooling wall that is up to the standards is placed on the steel platform of setting up after adopting on-the-spot truck crane block-by-block to unload, and must not overlappingly put.
According to on-site actual situations, choose the water source nearby, cause the pressure testing platform by sebific duct, establish steel water tank on the platform, store enough water yields.Prepare two 30kgf test pumps, every bench teat press pump is joined each 1 of water intaking valve, reverse checkvalve and draw-off valve, measurement instrument two covers.The selection principle of pressure: manometric full scale should be 1.5～2 times of maximum pressure value, and the tensimeter accuracy class is not less than 1.5 grades, is installed in the position of being convenient to observe.This engineering pressure table is elected Y-100.0-2.5MPa as, 1.5 grades of accuracy classes, and tensimeter must be up to the standards through legal metrological supervision mechanism and stick conformity certification after the lead sealing and can use.
Pressure testing connects adopts flexible pipe or high-pressure rubber pipe to link to each other with cooling wall, and the cooling wall joint is connected with steel pipe with homemade elastomer connector, and test pressure is 1.5MPa, after hydraulic pressure is increased to the 1.5MPa layer, keeps this pressure 30 minutes, and pressure drop is not more than 3% for qualified.
General work pressure test 3～4 people, per 4～6 cooling walls are one group of whole pressure testing, before the mouth of pipe connects structure for pressure test, earlier with flexible rubber hose to the cooling wall pipeline of pressure testing is filled water, again each pipeline is together in series with the pressure testing flexible pipe, with adjustable wrench or pipe wrench with mouth of pipe nut tightening.The series connection pipe end connects tensimeter and exhausr port (effect of exhausr port is that the air in the assurance flexible pipe is discharged smoothly), open motor test pump or handle manual pressure test pump, after discharging air, close terminal exhausr port, after boosting to 1.5MPa, observing the mouth of pipe and each joint has the ne-leakage situation, if handle after the seepage pressure release is arranged, forbids band to be pressed and handles.During the hydraulic testing, temperature is lower than 5 ℃ must take antifreezing measures, must blow interior liquid although pressure testing is intact.
In the pressure testing process, operating personnel stand in outside test cooling wall 3m, avoid joint to jump out and hurt sb.'s feelings.During the pressure testing, warning line should be set, by special messenger's nurse, with hydraulic testing unrelated person No Admittance around the pressure testing cooling wall; Pressure testing finishes and sends to the on-the-spot signature affirmation of managing by the technician, and the cooling wall of finishing pressure testing is numbered (consistent with cooling wall self numbering), enters next group cooling wall work pressure test simultaneously.
In the pressure testing operating process, adopt steel pipe to be connected in series interchangeability and the ease-to-operate that connects between the cooling wall pipe that can't guarantee different spacing, exchange through project technology groups multi-argument, change the steel pipe serial connection into the high pressure rubber hose serial connection, solved interchangeability and the versatility of use like this.
The pressure testing of cooling wall monomer, what adopted is the method for being welded to connect in the past, be connected technology with the rubber hose expanded joint and compare, many, the long construction period of this method operation, progress can't guarantee.Pressure testing finishes, and also need prescind joint and to the former mouth of pipe groove of polishing.Increased the demand of electroplating equipment wielding machine, wlding and special work post, construction cost is very high.Substantially use is eliminated in the pressure testing of cooling wall monomer.Adopt the utility model, need not welding, interface rate is fast, and pressure testing finishes and removes immediately, repeatedly utilizes, and uses and only rubber hose is changed later on for 30 times, does not influence cooling wall after the dismounting pipe arrangement is installed, and the mouth of pipe need not secondary treating.Above two kinds of methods are carried out economic analysis contrast, and more than 4100 mouth of pipe of cooling wall adopts in the rubber hose expanded joint connection to save surplus the construction cost 30 ten thousand yuan by calculating the comparable pressure-measuring method that is welded to connect, and saves 45 days durations.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
