Automatic test device for performance of temperature sensor in fire damper and test method

Abstract

The invention relates to an automatic test device for the performance of a temperature sensor in a fire damper and a test method thereof. The test device includes a water bath, a fire damper, and a display PLC controller; a vertical electric pusher is fixed on one side of the water bath. Rod, the top of the telescopic rod of the electric push rod is provided with a fixed cap, the upper part of the fixed cap is fixed with a vertical rod, the vertical rod is fixed with a monitoring camera, the side of the fixed cap is fixed with a horizontal rod above the water bath, and the horizontal rod has Clamping device; the connecting wire of the temperature sensor sample on the fire damper is fixed by the clamping device on the horizontal bar so that the temperature sensor sample is suspended on the horizontal bar; the temperature control of the PLC controller and the water bath are respectively displayed. Devices, electric push rods, surveillance cameras, fire dampers, and temperature sensor samples on the fire dampers are connected by control wires. The invention replaces the traditional manual operation test, reduces human interference factors, realizes detection automation, and improves detection quality and efficiency.

Description

Technical field [0001] The invention relates to the technical field of fire protection product detection, in particular to an automatic test device for the performance of a temperature sensor in a fire damper and a test method thereof. Background technique [0002] The fire damper is installed on the air supply and return ducts of the ventilation and air conditioning system. It is usually open. In case of fire, when the flue gas in the duct reaches a certain temperature, it will be closed to block the smoke and fire. This requires the fire damper The temperature sensor should not make the fire damper work at a certain temperature. When the temperature reaches a certain temperature, the fire damper shall be closed within a specified time, that is, the inactivity and performance of the thermosensor in the fire damper shall be tested. The sensor performance test is completed by manual operation, the detection quality and efficiency are not high, and there are human interference fact...

Problems solved by technology

[0002] The fire damper is installed on the air supply and return pipes of the ventilation and air conditioning system. It is normally open. In case of fire, when the smoke in the pipe reaches a certain temperature, it will be closed to block the smoke and fire. This requires the fire damper The temperature sensor should not make the fire damper work at a certain temperature, and the fire damper should be closed within the specified time when it reaches a certain temperature, that is, to test the non-action and action performance of the temperature sensor in the fire damper. The performance test of the sensor is done manually, the quality and efficiency of the test are not high, and there are human interference factors
