A leak detection system for automobile water pump cover plate

Abstract

A leak detection system for automobile water pump cover plate, characterized in that it includes: an airtight detection platform, a power module, a PLC controller, an airtightness detection module, a counting storage module and a human-computer interaction module, and an airtight detection platform It includes a pressure detection module, an inflation module, a hole detection module and a comparison module, and is characterized in that: the output end of the pressure detection module is electrically connected to the inflation module, and the pressure detection module is used to measure the inflation pressure of the inflation module in real time and convert it into An electrical signal, the output end of the inflatable module is electrically connected to the hole detection module. The invention can improve the automation of the steps of detecting the cover plate of the automobile water pump, and the judgment of the staff on whether the cover plate of the automobile water pump is qualified is clearer and simpler, so that it is convenient to find various problems in the production process in time, so that the staff can quickly deal with them , to ensure the detection efficiency, and can accurately measure the production data, so that it is convenient for the staff to carry out statistics.

Description

technical field [0001] The invention relates to a detection system, in particular to a leakage detection system used for an automobile water pump cover plate. Background technique [0002] At present, in the cylinder block of the automobile engine, there are many water channels for cooling water circulation, which are connected with the radiator (commonly known as the water tank) placed in the front of the automobile through water pipes to form a large water circulation system. On the upper water outlet of the engine, A water pump is installed, which is driven by the fan belt to pump out the hot water in the water channel of the engine block and pump in the cold water. There is also a thermostat next to the water pump. When the car is just started (cold car), it is not turned on, so that the cooling water does not pass through the water tank, but only circulates in the engine (commonly known as small circulation). When the temperature of the engine reaches 95 degrees or more...

Problems solved by technology

Air tightness testing refers to using a specified method to test the specified technical performance indicators of an object, which can quickly distinguish qualified products and ensure the safety of use. The detection method of the pump body cover is usually manual detection, that is, manually Put the cover plate of the automobile water pump into the water and pass in the pressure gas to observe whether there are bubbles generated on the cover plate of the automobile water pump; this method has a high degree of manual participation, so it requires a lot of work for the workers, resulting in low work efficiency; at the same time, by judging the water pump The way to detect whether there are air bubbles on the cover plate is to detect the water pump cover plate, which has the problem of large human factors and low accuracy
