How do the hydraulic cylinder type points

'Hydraulic cylinder', its specific content and problems of knowledge, today small make up will continue, because these are necessary for us to understand and master, can't be a little careless, otherwise it will affect the learning process, which is the deep and comprehensive understanding of the product, so then, before it's we have to expand its specific content, so that you can let everybody to learn in time, in order to know more about the hydraulic cylinder of this product. Hydraulic cylinder, the type is very much, if according to the working pressure to points, can be divided into low pressure, medium pressure and high pressure and high pressure of these four, so be specific choice according to different actual conditions. If it is mechanical parts for machine tool, then is used in low pressure hydraulic cylinders, pressure rating. — 。 MPa。 In addition, the high pressure rating of the hydraulic cylinder pressure for - MPa, high pressure hydraulic cylinder is - MPa。 The leakage of hydraulic cylinder, the general is inside leaking or leaked, the main is in the joint of the end cover and cylinder, as well as some fit clearance. Inside leaking, it mainly makes the oil heating, make its volumetric efficiency, and affect the working performance of hydraulic cylinder. And leaking, can cause the loss of the oil, will pollute the environment. So, whether it's inside leaking or leaked out, and we all should be avoided.
