Product Details

1. concept:

The equipment is developed according to industry standards, used to test the wind pressure resistance performance of exterior insulation system. In the control mode of the use of advanced control system, pneumatic control valve precise pressure regulation, microcomputer automatic control, display record process control curve, print the original record and test results of a number of automatic control functions. The overall design has the advantages of wide range of adaptation, simple operation, stable performance, high control precision, accurate data collection, low comprehensive noise and many other advantages.

Test items:
It is used to detect the wind pressure resistance of building exterior wall insulation materials.

3. basis standard:

JGJ144 "external insulation engineering technical specification"

JG/T149 "expanded polystyrene board thin plastering exterior insulation system"

JG/T158 "rubber powder polystyrene particles exterior insulation system materials"

4. technical parameters:

Specifications of testable parts: length 2500 × width 2000mm.
Anti-wind pressure performance: pressure difference: ≤-10000Pa, accuracy ≤ 5%; Pressurization mode: frequency converter automatically pressurizes.
Test results: data calculation, grading, test report and original records can all be processed by computer.
Time control deviation of pressure pulse process: boost: 0.7~1.0s, continuous: 2 ~ 4S depressurization: ≥ 4s, intermittent: ≥ 3s.
Number of cycles: can be set, frequency control accuracy of 100%.
Power supply requirements: AC380V 10kW.
Overall dimensions of the static pressure box: length 3000 × width 700 × height 2500mm.
Laboratory space required: length 6000 × width 7000 × height 4000mm.

There are two ways of moving the sample frame: track type and crane type;
9. The orbital type can test two specimens at the same time, and the other two specimens are cured;

10. The crane type can install two test pieces at the same time, and the other multiple test pieces can be cured.

5. structure:

power system
Pressure supply device: 2 GTC-1 centrifugal fans with power of 11kW, full pressure of 7000 Pa and rotating speed of 2930 r/min are adopted.

Pneumatic switching valve: When the system pressure reaches the set value, the negative pressure pulse required in the standard is formed by controlling the switch state of the two pneumatic switching valves.

Leakage valve: according to the standard requirements to adjust the system pressure lower limit and fall time.

Static pressure box fixed hole, convenient specimen clamping, while ensuring the entire box and box and the connection between the sealing performance of the test piece.
Mobile trolley mechanism: two groups of specimens can be suspended at the same time, which is convenient and flexible to use.
During the detection of the monitoring system, observe the sample state.
measurement and control system
The differential pressure sensor is used to measure the pressure difference between the inside and outside of the static pressure box. The measuring range of the differential pressure sensor is-15Kpa, and the accuracy is 2.5.
The data acquisition card is inserted into the computer case, and its function is to collect the voltage signal of each sensor, output digital signal to control the strong electric relay, and output analog signal to control the speed of the fan, so as to realize the adjustment of the wind pressure.
The measurement control software interacts with the entire equipment through the data acquisition card, which can collect and process data, control according to the data, and later data processing and inspection reports, original records writing and printing.
