Abstract

The invention relates to the technical field of pipeline leakage test, and discloses test equipment, comprising a detector, a fixing tooling and an on-off device. The fixing tool comprises a first plugging device, a second plugging device and a fixing device, wherein the first plugging device is provided with an exhaust passage and is hermetically connected with an oil outlet end of an oil pipe, an air inlet of the exhaust passage is communicated with the oil outlet end; the second plugging device is provided with an air feeding passage connected with an air outlet of the detector, and is hermetically connected with an oil inlet end of the oil pipe, and an air outlet of the air feeding passage is communicated with the oil outlet end; the fixing device can fix the oil pipe. The on-off device is connected with an air outlet of the exhaust passage. Whether a check valve in the oil pipe is on or off or leakage rate of the oil pipe is tested by controlling the on-off device. The oil pipe isfixed and then subjected to hermetical connection, so that air leakage due to poor sealing effect when the oil pipe is moved accidentally can be reduced and test accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of pipeline leakage testing, in particular to a testing device. Background technique [0002] As we all know, the oil pipes on the car work in a high-pressure environment. In order to ensure that the oil pipes do not leak oil, the pass rate of these pipes is extremely high, and all pipes must be tested for leaks. [0003] Such as figure 1 As shown in the oil pipe, an oil drum 103 is arranged on the oil pipe, and a check valve is installed in the oil pipe to prevent the oil from flowing backward. The oil outlet end 101 of the oil pipe is provided with a sealing gasket, which facilitates the sealing connection with the oil outlet of the oil tank. The upper ring of the oil inlet end 102 is provided with a protrusion, and the oil inlet end 102 stretches into the oil inlet of the machine, and a sealing ring is arranged between the oil inlet and the protrusion, and then fixed by a nut. In the past, the leakage ...
