An energy-saving device for automatically detecting the airtightness of an exhaust manifold and its application method

Abstract

The invention provides energy-saving equipment for automatic detection of air tightness of exhaust manifolds and a utilization method of the energy-saving equipment. The energy-saving equipment comprises a detection vehicle, a starter and alarm and a water storage pool. Three surfaces of the detection vehicle are provided with a plurality of longitudinal and transverse slide ways, and a pluralityof clamping devices and sealing devices with hook claws extend inwardly from the longitudinal and transverse slide ways. The clamping devices and the sealing devices are connected with power devices,and tails of the power devices penetrate the longitudinal and transverse slide ways and move on the longitudinal and transverse slide ways. The detection vehicle is provided with an automatic water injection pipe fitting and an automatic air delivery pipe fitting, and the starter and alarm is arranged on the outer side of the detection vehicle and connected with a control system through a sensor.The water storage pool is arranged on the right side of the detection vehicle and provided with a circulating water device connected with the detection vehicle. By means of high-pressure compression for detection of air tightness of the exhaust manifolds, the energy-saving equipment is direct and evident in detection effect and high in applicability and is provided with a water circulation systemto play a great role in energy saving.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to an energy-saving device and a use method for automatically detecting the airtightness of an exhaust manifold. Background technique [0002] The exhaust manifold is connected to the cylinder block of the automobile engine, and the exhaust gas discharged from each cylinder is collected and introduced into the exhaust main pipe, with a conduit with branch lines. At present, the common practice of various engine manufacturers is to package the three-way catalytic converter used to purify the exhaust gas in the exhaust manifold. If the airtightness of the exhaust manifold is not good, the exhaust gas will not only pollute the car body, but also reduce the exhaust gas of the vehicle. System life, more seriously, will cause pollution to the atmospheric environment. After the finished exhaust manifold is completed, it needs to pass the air tightness test. In the existing technology, th...

Problems solved by technology

However, the former has the risk of radiation injury and requires higher professional quality of operators; the latter is affected by the fixed position and number of sealing devices, and a single device can generally only test the airtightness of exhaust manifolds of a series of cylinders. The flexibility is poor, and the specific leakage point cannot be accurately judged, which affects the use effect
