Guide bushes and seals for hydraulic cylinder components of hydraulic presses

The function of the hydraulic cylinder part of the hydraulic press is to convert the pressure energy of the liquid into mechanical work. After the high-pressure liquid enters the cylinder, it acts on the plunger (or piston), and transmits the force to the workpiece through the movable beam to form the workpiece. The hydraulic cylinder part is one of the main parts of the hydraulic press.
Guide bushes and seals for hydraulic cylinder components of hydraulic presses
(1) Hydraulic cylinder guide sleeve of hydraulic press No matter what kind of structure of the hydraulic cylinder, in order to ensure the correctness of the movement direction of the piston or plunger, it is inseparable from the guide sleeve device. The guide sleeve plays a guiding role when the plunger (or piston) reciprocates. The ratio H/dl of the length of the guide sleeve to the diameter of the working plunger is generally 0.5-1.0, for the vertical plunger cylinder is generally 0.4-0.8, for the horizontal plunger cylinder is generally 0.8-1.5, the value range of large hydraulic presses too small.
(2) The function of sealing is mainly to prevent the leakage of high-pressure liquid in the hydraulic cylinder to maintain the pressure of the liquid, and also to prevent the entry of external foreign objects (such as air, dust, water, etc.). The quality of the seal directly affects the production status. When the sealing quality is not good, it will cause a large amount of leakage of working fluid, decrease in system efficiency, inability to maintain pressure, insensitive manipulation, unstable movement, and environmental pollution.
Basic requirements for sealing: good sealing performance, can automatically improve sealing performance with the increase of liquid pressure, low friction resistance, small wear, long life, simple use and maintenance, easy disassembly and replacement, low cost and easy manufacturing.
Therefore, the sealing material should have the following characteristics: within a certain temperature range, good chemical stability, insoluble in working liquid, not five-phase corrosion and adhesion in contact with metal; within a certain time range, no softening or hardening, good elasticity, not easy to Deformation, good wear resistance, small friction factor, easy to manufacture, low cost, etc.
Commonly used sealing materials are oil-resistant rubber and cloth rubber, polyurethane rubber, polyvinyl chloride plastic, polytetrafluoroethylene plastic, nylon, etc. There are many types of commonly used sealing shapes, and the most common applications are V-shaped, U-shaped, Y-shaped, Yx-shaped, O-shaped, herringbone and so on.
Shanghai Yingxin World Machinery Co., Ltd. offers a ton of features and capabilities to help you acquire and retain customers, boost sales and manage contacts.
Shanghai Yingxin World Machinery Co., Ltd.’s mission is to provide high quality care and services to our members and to be profitable in the process.
The more people who do a certain thing, the more likely others are to do it as well. When WORLD can demonstrate their popularity or satisfaction across a wide customer base, other consumers are more likely to buy in as well.
In a nutshell, is actually an ultimate solution for automatic power press machine and underestimating its value cost you higher than anything else. So grab it before you miss the boat.
automatic power press machine mechanical power press will help keep your automatic power press machine in a automatic power press machine state.
