Slovakia hydraulic cylinder,punch machine hydraulic cylinder manufacturer,punch machine hydraulic cylinder
(Slovakia punch machine hydraulic cylinder,produced by Hebei Hengyu company）
punch machine hydraulic cylinder are widely used in Slovakia，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed punch machine hydraulic cylinder for customers from Slovakia.
The definition of the minimum starting pressure of the punch machine hydraulic cylinder refers to the minimum working pressure of the punch machine hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the punch machine hydraulic cylinder parts and the size of the sealing friction.
Repair method of small range wear of oil punch machine hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.
We can not just consider the price and ignore the quality when we purchase the punch machine hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the punch machine hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the punch machine hydraulic cylinder is not required.
The quality of the punch machine hydraulic cylinder can not be ignored in the purchase of the punch machine hydraulic cylinder. The punch machine hydraulic cylinder is the main component of the punch machine hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. punch machine hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of punch machine hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.
What is hydraulic cylinder？ How to use hydraulic cylinder？ what is the application of hydraulic cylinder?
Hydraulic cylinder is the hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating movement (or swing movement). 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 hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston, piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential. Hydraulic cylinders are mainly used in machinery.
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.
