Description
技术领域technical field
本实用新型涉及压铸机技术领域，具体地说，它是一种压铸机油冷却器检漏装置。The utility model relates to the technical field of die casting machines, in particular to a leak detection device for a die casting oil cooler.
背景技术Background technique
压铸机油冷却器由铜管分隔成两个空间，铜管里面通水，外面通液压油，通过水的流动降低油温。如果油冷却器产生泄漏，会导致液压油进入水的一边，污染整个冷却水系统；同时水也会进入液压油一边使油变质，影响设备使用寿命。The die-casting oil cooler is divided into two spaces by copper pipes. The copper pipes pass water inside and hydraulic oil outside, and the oil temperature is lowered by the flow of water. If the oil cooler leaks, it will cause the hydraulic oil to enter the side of the water and pollute the entire cooling water system; at the same time, the water will also enter the hydraulic oil and deteriorate the oil, which will affect the service life of the equipment.
以前压铸机油冷却器是利用压缩空气来检漏，由于压缩空气（压缩空气气压为0.5MPa)压力较小，导致在泄漏量小的情况下无法检出，检测正确率低，从而影响设备维修进度。In the past, the die-casting oil cooler used compressed air to detect leaks. Due to the low pressure of the compressed air (compressed air pressure of 0.5MPa), it could not be detected when the amount of leakage was small, and the detection accuracy rate was low, thus affecting the progress of equipment maintenance. .
因此，现有技术有待于提高和改善。Therefore, the existing technology needs to be improved and improved.
