The analysis of the main factors affecting the quality of cylinder

The main factors influencing the quality of cylinder analysis shows that the main factors influencing the quality of cylinder what time is it? There are mainly three, as the design experience, the machining quality and the use of maintenance, the following is to introduce the three points into action (respectively, specific as follows. 。 Design experience of a veteran hydraulic engineers in the design of cylinder, must know the following parameters, as follows: cylinder diameter, stem diameter, stroke; Pressure of work or cylinder load; Working environment temperature; Working medium; Running speed; Other parameters, such as the connection form, installed size diameter, stem diameter, stroke, etc. Close to the national standard or other standard as far as possible, avoid to choose non-standard sizes, or increase the processing difficulty and manufacturing cost. According to decide the length of the guide cylinder stroke length. According to the working pressure or load to check the strength of the cylinder, piston rod, screw, etc. At the same time, working pressure, ambient temperature, working medium, running speed is crucial in chosen by seals. Different types of sealing pressure, temperature, medium, the speed is not the same, water glycol medium cannot use polyurethane sealing, can only use the rubber seal; Cylinders must be used when running speed slip ring seal, run slower when available Yx type, U type, V type combined sealing, etc. ; Under the environment of high temperature and high pressure with fluorine rubber seal; Run faster with a cushion cover, cushion valve must be considered. In addition, the material selection of spare parts must also be careful. In short, the oil cylinder design is the first step on the product quality, if the design is wrong, the processing quality again good also cannot meet the requirements. 。 The machining precision of machining precision cylinder depends on the equipment level, production technology and detection means. There are two kinds of cylinder processing methods commonly used, one is rough boring boring and rolling, generally use # seamless steel tube, this method the processing quality well, but the cost is high. Another method is to use # cold drawn seamless steel tubes, honing again, the cost is the bottom. The piston rod processing must be quenched and tempered before straightening, the piston rod coating thickness is generally not less than. mm。 Piston machining must be in strict accordance with the manual given groove dimension tolerance zone of seals. 。 If use maintenance oil cylinder to fully meet user requirements, in addition to the above two factors, and to correctly use and regular maintenance. Cylinder before use to vent, buffer regulator to adjust to a reasonable position, cleanness of the oil should be check regularly, regular cleaning dust on cylinder, also pay attention to waterproof, fire prevention.
