Problems solved by technology

Although the device can simply, accurately, safely and reliably detect the instantaneous pressure-bearing capacity of the bulb, it cannot test the ultimate pressure-resistant capacity of the bulb, so it cannot really detect the ultimate pressure-resistant quality of the batch bulb

Abstract

The invention discloses an extreme pressure resistance testing device for a bubble cap. The extreme pressure resistance testing device comprises a conveying pump used for conveying a pressure measuring medium into the bubble cap, a sensor used for testing a pressure value in the bubble cap, and a control valve used for controlling the conveying speed of the conveying pump, wherein the control valve is used for regulating the conveying speed of the conveying pump according to a signal fed back to the controller by the sensor. According to the extreme pressure resistance testing device, the pressure measuring medium is rapidly conveyed into the bubble cap through the conveying pump to ensure that the pressure in the bubble cap reaches a value primarily set by a user, and then slowly conveyed into the bubble cap through the conveying pump to ensure that the set value of the pressure in the bubble cap starts gradually increasing until the bubble cap is burst, and then the sensor or an external machine records the pressure value when the bubble cap is burst, therefore, an extreme pressure resistance value of the bubble cap is test simply, safely, conveniently and rapidly.

Description

technical field [0001] The invention relates to the field of light bulb testing equipment, in particular to a bulb shell ultimate pressure test device. Background technique [0002] At present, many manufacturers will test the pressure bearing capacity of the bulb in the process of producing the bulb, so as to ensure that the bulb can withstand the instantaneous expansion pressure generated by the internal tungsten wire fusing without explosion, and ensure the safe use of the bulb. As shown in the invention patent with the publication number of 102589981A, the inventor has invented a bulb pressure testing device for the existing bulb testing problem. The device injects rated air pressure into the bulb instantly to simulate the moment when the filament explodes. Impact force, used to test the impact resistance of the bulb. Although the device can simply, accurately, safely and reliably detect the instantaneous pressure-bearing capacity of the bulb, it cannot test the ultimat...
