Cylinder maintenance methods and buffering characteristics analysis

Cylinder maintenance methods and buffering characteristics analysis in practical application of automated production, as a kind of pneumatic cylinder actuators is the most widely used in pneumatic transmission. But general cylinder are single stroke output, although through the control valve, also can get different output in the range of travel itinerary, but the use of control valve is difficult to obtain accurate positioning. Cylinder in use process, we compare the attention buffer characteristics of gas cylinder, which is in order to better to maintenance of cylinder, exactly what are the characteristics and the relationship between the method? A, preventive maintenance and the method of cylinder: right. Cylinder repair to assembly, parts must be clean, to prevent damage of sealing ring is cut, in particular, pay attention to the dynamic sealing ring installation direction. 。 Use should be regularly check each part of the cylinder in the presence of abnormal phenomenon, the connecting parts for loose, such as the activities of the cylinder parts of the shaft pin type installation should add lubricating oil regularly. 。 Cylinder to be removed when not in use for a long time, all the processing surface should be coated rust-proof oil, into the vent should add dustproof plug. 。 Cylinder repair to assembly, parts must be clean, must not be dirt into the cylinders. Shall prevent damage of sealing ring is cut, and special attention dynamic seal installation direction. 。 Make a cylinder month, season, year of maintenance system, maintenance and management of reference direction valve system specified in the content. Cylinder cushion performance: by adjusting the air pressure and needle valve opening buffer, buffer cavity under different test conditions and main gas path parameters such as pressure, cylinder stroke and vibration acceleration, and analyzed the buffer, owe the buffer and the best buffer gas buffer properties of several typical. Three, factors effect on the characteristic of cylinder cushion has the following: the piston and cylinder end cover mechanical collision is the main factor of impact vibration; There are still have some buffer process mechanical collision, resulting in the buffer effect of variation; Best air cushion only exist in certain conditions. When the working parts of large cylinder driving quality and fast speed, a sudden stop motion state or reversing, can produce shock and vibration, therefore must set the buffer device. According to the work requirements and conditions, correct selection of the type of cylinder. For cylinder to travel no impact on the terminal phenomenon and impact noise should choose buffer cylinder; For light weight, choose the light cylinder; Required to install a space narrow and short journeys, optional thin cylinder; With transverse load, optional with guide rod cylinder; Brake precision demanding, choose the lock cylinder; Do not allow the piston rod rotation, optional with functions of stem not rotary cylinder; High temperature environment to choose heat cylinder; In corrosive environment, should choose the corrosion resistance of cylinder. In harsh environments such as dust, need piston rod out of the dust cover installation. Asked to choose when no pollution to oil or no oil lubrication cylinder, etc.
