Problems solved by technology
[0004] As an important connecting part of the fuel pump, the oil outlet seat must be guaranteed in terms of airtightness, so we need to test its airtightness. The current airtightness testing equipment is mainly used for testing containers, which cannot be applied In the oil outlet seat, and the current air tightness test mainly uses the pressure gauge to read the air tightness, because the pressure gauge may also leak during the installation process, and the reading of the pressure gauge is not accurate enough, so the result will not be correct. very accurate

The invention discloses an air tightness testing equipment of oil outlet seat production, which comprises a bottom plate, a detection box, an air inlet pipe, and a collection box, wherein a wheel carrier is arranged bellow the bottom plate, an universal wheel is arranged bellow the wheel carrier, the detection box is arranged above the bottom plate, the gas collection box is arranged inside the detection box, a first pressure sensor is arranged in the inner side of the gas collection box, and a controller is arranged inside the gas collection box. The device is simple in structure and convenient to use, is suitable for the oil outlet seat, arranged with the universal wheel, so that the device is convenient to move, and the oil outlet seat is conveniently subjected to air tightness testing,air pressure is detected through the pressure sensor, so as to avoid errors caused by the problem that install the pressure gauge to bring the leak and pressure gauge reading is not accurate, and ensure the stability of the oil outlet seat in the testing process through the cooperation of the first electric telescopic rod and the second electric telescopic rod.
Description
technical field [0001] The invention relates to the field of oil outlet production, in particular to an air tightness testing device for oil outlet production. Background technique [0002] The oil outlet seat is installed on the pump core in the fuel pump assembly of the automobile (gasoline engine), and plays the role of controlling the oil outlet and closing of the fuel pump. It is a part of the fuel pump. The oil outlet seat is generally formed in one piece. It must be tested for airtightness to ensure that it will be put into use. [0003] Air tightness refers to the gas sealing performance of equipment, and air tightness test refers to a kind of tightness test using gas as the pressurized medium to prevent leakage of pressure vessels. This is for those pressure vessels whose contents are extremely toxic, highly hazardous, or designed to allow a small amount of leakage, the airtightness test must be carried out. The airtightness test can only be carried out after pass...
