Fireproof door closer high temperature performance testing machine door detection equipmentProduct Introduction

Scope of application

Fireproof door closer high temperature performance testing machine door detection equipmentPerformance of fire door closers at high temperatures.

meet the standard

Comply with Section 8.3 of GA 93-2004 "Fire Door closers" for the performance of fire door closers at high temperatures

Main technical parameters

1. Power supply requirements: AC380V, 10kW

2. Operation interface: Colorful 7-inch touch screen

4. Test station: There are holes for hanging hooks at both ends of the single station

5. Traction line:

The traction line adopts steel stranded wire with a length of 500mm ranging from 1.0mm to 1.2mm. The overall dimensions of the equipment are as follows:

Length x Width x Height (mm) 1050mm x 1200mm x 1900mm

7. The experimental equipment consists of fire doors, dials, load cell hooks, load cell insulation covers, displacement gauges, traction wires, heaters, thermocouples, temperature controllers, timers, and counters;

8. Test fire door specifications

Width x height (mm) 450mm x 1000mm, door leaf mass 40kg

9. Weight distribution 90kg, maximum load (including door 40kg): 130kg. By changing the weight distribution, the weight of the door leaf can be increased to meet the requirements of different specifications of fireproof door closers

10. Insulation cover size:

770mm x 905mm x 1450mm insulation cover material: The front is made of heat-resistant transparent high-temperature glass, and the other parts are made of filled insulation cotton.

11. Heater: The heater can be electrically heated. The heating system has a circulating air duct with heating tubes installed inside.

12. Thermocouples: There are two K-type thermocouples with a wire diameter of 0.5mm and a temperature measurement range of 0'C-200 ° C. One thermocouple is located directly above the fire door closer, and the other thermocouple is located on the side of the door shaft of the fire door closer. The distance between the temperature measurement end and the fire door closer is 50mm;

13. Temperature controller

The temperature controller controls the output of the heater to raise the temperature inside the insulation cover to 150 ℃ at a rate of 10 ° C/min and maintain a constant temperature. The maximum allowable error for temperature control is+10 ° C

14. Scale dial:

Made of SUS304 stainless steel material, installed at the lower part of the door leaf, with a division value of 1 and a range of 0-90 °. The placement position is the outward arc of the projected arc on the ground when the edge of the door with a handle is opened;

15. Load cell hook: The position of the load cell hook is 500mm from the lower edge of the door leaf and 440mm from the rotation of the door shaft.

16. Dynamometer:

The measured load of the dynamometer should be within the range of 20% -80% of the dynamometer's range, and the maximum allowable error of the dynamometer is ± 2N. The measured torque range is 0-120N · m, the force arm is 0.44m, and the dynamometer range is 0-273N. 17. Displacement meter:

The contact point of the displacement meter is 400mm away from the rotation of the door shaft and 100mm away from the lower edge of the door leaf. The maximum allowable error of the displacement meter is 0.01mm. It has a digital display function. It has convenient disassembly and assembly functions, and needs to be removed during durability testing:
