At least two parallel-connected blower fans are used to feed wind into the simulated pressure tank by means of positive wind pipe and negative wind pipe, and according to the feedback signal of pressure sensor the piston valve position can be regulated and the flow rate can be controlled. The measurement and control system utilizes the sensors placed around the tested component to collect signal, input it into measurement and control microcomputer and output measured data.
Description
The present invention relates to a kind of door and window dynamic wind pressure property checkout equipment.
Existing door and window Performance Detection all is that testing laboratory is detected, and testing result can only be responsible for the sample window, can't reflect the actual conditions of engineering, exists sample presentation doors and windows performance and the inconsistent defective of engineering doors and windows quality.Because window frame making, attached frame, glass and part annex will be installed after last wall, and fabrication and installation may not be producers, often cause responsibility unclear, dispute is continuous, and its basic reason is exactly that huge, complicated checkout equipment makes the installation quality of door and window can not obtain on-the-spot the detection.
The purpose of this invention is to provide a kind of simple in structure, accurate, portable equipment in situ testing dynamic wind pressure property of building door and window of measurement, realize that the scene of the pneumatic pressure of building doors and windows is detected, thereby improve construction quality and product quality.
The technical scheme of equipment in situ testing dynamic wind pressure property of building door and window of the present invention: this equipment comprises simulated environment system, the power source of supplying with this system and the TT﹠C system that places around the test specimen, it is characterized in that:
Horizontal near-ring border system is by forming with the trickle shower nozzle of micro pump control and the simulated pressure case that is fixed on the inboard hole of window;
Power source places among the headstock, by the blower fan of at least two parallel connections by positive pressure ventilation pipe and the pseudopressure case air-supply sidelong of negative pressure airduct, headstock is divided into zone of positive pressure and negative pressuren zone by dividing plate, be communicated with positive pressure ventilation pipe and negative pressure airduct by ventilating opening, the piston valve of regulating air quantity is respectively arranged in two airducts, the screw rod that the piston valve center connects links to each other with drive motor, according to the feedback signal regulating piston valve position and the Control Flow of pressure transducer;
TT﹠C system is by placing displacement transducer, pressure transducer and the Temperature Humidity Sensor acquired signal around the test specimen and importing observing and controlling microcomputer output measured data.
Above-mentioned simulated pressure case is connected with screw by angle aluminium with rectangular metal pipe framework by transparent panel, is fixed on by support member and forms the plenum chamber space on the window opening mouth.
Above-mentioned trickle shower nozzle has four copper umbrella mist type shower nozzles, is fixed on the spray frame that is installed on the side hole outside window.
Temperature Humidity Sensor in the above-mentioned TT﹠C system is macromolecule membrane capacitive moisture sensor and semiconductor integrated temperature sensor.
Above-mentioned displacement transducer is the differential transformer sensor, places on the displacement sensor bracket.
Testing process of the present invention: put signal by non-electricity such as each sensor acquisition displacement signal, temperature signal, moisture signal, atmospheric signal, wind velocity signal, pressure signals, send transmitter to be transformed into voltage, current signal, send into collector again and import portable computer again and carry out data processing and export the blower fan control signal through testing conditions settings, air penetration performance, rain leakage performance, blast deformation performance inspection module, the air pressure control procedure is a close-loop feedback control.When detection of negative pressure, the piston valve of negative pressuren zone moves left to the end, and wind enters from the negative pressure airduct, is divided into two parts by ventilating opening by piston valve after the blower fan pressurization, and a part enters forbay, for forbay provides blast; Another part directly leads to atmosphere, adjusts the position of piston valve, can change the ratio of two parts gas, thereby reaches the purpose of regulating pressure.Simultaneously, no matter the malleation piston valve is in any position, can both guarantee that blower fan is in the full flow duty all the time, has guaranteed the safety of blower fan.When malleation detected, opposite with detection of negative pressure, the malleation piston valve moved left to the end, regulated the negative pressure piston valve and changed pressure differential.Bleed to forbay this moment, and the test specimen surface produces pressure differential, is negative pressure in the case, and the outside is a high pressure, and the malleation that is equivalent to standard code testing laboratory testing conditions detects.
According to standard GB 7106～7108-86, the key technical indexes of the present utility model is as follows: maximum detection test specimen specification 1500 * 1500mm; Air penetration performance: flow 200m
3/ h, pressure reduction: ± 100Pa; Rain penetration performance: trickle amount 21m
2.min, pressure reduction: 500Pa; Blast deformation performance: displacement 0-20mm, pressure reduction: ± 3500Pa.
Advantage of the present invention is: detect with testing laboratory in the past and compare, censorship sample window performance and the inconsistent defective of engineering doors and windows quality have been solved, simultaneously can detect the door and window installation quality, consistent with the moving blast checkout equipment of testing laboratory building doors and windows, all testing process is handled automatically by computing machine, select by master menu, man-machine conversation mode's operation, have simple in structure, carry with easy to use, accurately and reliably, cheap advantage, be used for the on-the-spot air penetration that detects after building doors and windows is installed in the body of wall hole, rain leakage, the blast deformation performance, the scene that is fit to the quality supervised department acceptances of work at different levels is detected.
