Leakage detector

Abstract

The invention discloses a leakage detector, belonging to the technical field of natural gas engine. The leakage detector comprises an encloser, wherein the encloser is internally provided with a water tank; a lifting device for the placement of a to-be-detected fuel gas part is arranged above the water tank; the encloser is also internally provided with a gas source for providing compressed gas to the to-be-detected fuel gas part; the encloser is provided with an opening allowing the fuel gas part to come in and go out; a safety door is arranged at the opening; and the encloser is also provided with a view window for viewing the fuel gas part in the water tank. After such the structure is adopted, the to-be-detected fuel gas part is connected with the gas source, the fuel gas part is placed on the lifting device, and the lifting device is responsible for placing the fuel gas part into the water in the water tank, so that the gas source supplies the gas to the to-be-detected fuel gas part to detect the gas tightness of the fuel gas part under the precondition of closing the safety door, and a detecting person can obtain the gas tightness condition of the fuel gas part safely and directly outside the encloser through a view window.

Description

technical field [0001] The invention relates to natural gas engine detection equipment, in particular to a leak detector for detecting the airtightness of gas parts of the natural gas engine. Background technique [0002] Natural gas engines have high requirements on the airtightness of gas components. At present, the airtightness test of gas components of natural gas engines is tested during the field test of the whole machine, which will lead to untargeted detection and inaccurate test results, such as One of the gas component injection valves of a natural gas engine has a maximum of 12 nozzles. It is impossible to detect which nozzle is leaking through the field test of the whole machine. If a leaking gas component is detected, the whole machine needs to be disassembled. , It is very troublesome to process the leaking gas parts, and when carrying out the field test of the complete machine, if some gas parts leak, there will be a relatively large safety hazard during the t...
