Background
Industrial gas and oil leakage is an important problem in the operation of a factory, and when leakage occurs, life safety can be endangered and the surrounding environment, namely ecological balance, can be damaged, so that life and property are seriously lost. Because of the large range of industrial production equipment, sealing elements are generally used for connection in places where operation or disassembly and assembly are often required. The sealing properties of the seal will be deteriorated by indirect or direct influences of various conditions. If the gas or oil leakage problem cannot be timely monitored by using a certain method or device and corresponding measures are taken, the leakage is rapidly enlarged over time, normal production is damaged, and economic loss is caused.
Traditionally, a flow method, an infrared spectroscopy method, a manual inspection method and the like are adopted for monitoring, the commonly used monitoring methods usually consume much labor and time, the monitoring accuracy and reliability are relatively low, and the method is not suitable for micro-leakage of ul/min level. The existing fixed online monitoring system has the following disadvantages: (1) the installation is complicated: the common fixed monitoring equipment needs to use a special gasket or valve, and field equipment needs to be reconstructed, so that the installation difficulty is increased; (2) the price is high: the general fixed monitoring equipment is complex to install, increases the cost, often needs thousands of yuan of selling price, and is difficult to be widely distributed. (3) The protection function is not available: under the condition that a large amount of leakage occurs in equipment, the general monitoring equipment cannot prevent the leakage liquid from dripping and splashing, and great threats are caused to the personnel safety and the equipment safety around the production equipment. (4) Has no passive function: general fixed monitoring facilities consume large power, need electric wire arrangement or solar energy power supply, and for inaccessible points and other places unsuitable for placing electric wires or solar energy power supply, great restriction is caused, and simultaneously, the equipment cost and the installation cost are greatly increased, and large-scale popularization is not facilitated.
