(India supporting cylinder,produced by Hebei Hengyu company）

supporting cylinder are widely used in India，because of clever hydraulic energy conversion，simple structure and reliable operation，powerful torque.So our company has designed supporting cylinder for customers from India.

Introduction to supporting cylinder:

There are some honeycomb holes in the inner wall of the supporting cylinder, piston or piston rod surface. How is this formed? When we repair the supporting cylinder, we can see that there are some honeycomb holes on the inner wall of the supporting cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the supporting cylinder is targeted to prevent. Is very necessary.

supporting cylinder piston rod material introduction: In general, we use 45 steel to produce supporting cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

supporting cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the supporting cylinder head itself is the guide sleeve of the piston rod, the supporting cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the supporting cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The piston rod of the supporting cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Answers to some questions about supporting cylinder:

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.

100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
