Description

The application of hydraulic cylinder/jack can be seen everywhere in coal mine production, such as scraper hydraulic cylinder/jack, transfer machine hydraulic cylinder/jack, self-moving tail hydraulic cylinder/jack, hydraulic support hydraulic cylinder/jack, etc. They have different classification and functions in different equipment and are also an important part of coal mining equipment. Therefore, the quality of hydraulic cylinder/jack needs to be strictly controlled, one of which is the leakage problem of hydraulic cylinder/jack, which is mainly caused by the poor joint:





(1) When the cylinder barrel and the end cover are connected with threads, the end cover is not fastened according to rated torque; The sealing ring has poor sealing performance.



(2) When the cylinder barrel and the end cover are bolted and connected, the parts of the joint part have burrs or assembly burrs, resulting in poor bonding, thus causing initial leakage; O - ring on the end face has fit clearance; The bolt won't tighten properly.



(3) The hydraulic cylinder inlet pipe joint is loose. Therefore, it is necessary to solve the pipe fitting vibration and other factors that cause the looseness of the pipe joint. Flange connection can be adopted for pipe orifice with pipe diameter greater than *5mm.



Details determine success or failure, and the high quality of each product requires attention to detail.
