Spain hydraulic cylinder,cargo elevator hydraulic cylinder manufacturer,cargo elevator hydraulic cylinder(Spain cargo elevator hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
cargo elevator hydraulic cylinder are widely used in Spain,because of high work efficiency,excellent fatigue and impact resistance,smooth movement.So our company has designed cargo elevator hydraulic cylinder for customers from Spain.
The definition of the minimum starting pressure of the cargo elevator hydraulic cylinder refers to the minimum working pressure of the cargo elevator hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the cargo elevator hydraulic cylinder parts and the size of the sealing friction.
In recent years, the processing process of the cargo elevator hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.
The method of sleeve cargo elevator hydraulic cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the cargo elevator hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the cargo elevator hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
The cargo elevator hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the cargo elevator hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The cargo elevator hydraulic cylinder is basically composed of cargo elevator hydraulic cylinder and cargo elevator hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.
