(Finland steel mill cylinder,produced by Hengyu Hydraulic Co., Ltd）

steel mill cylinder are widely used in Finland，because of excellent temperature resistance，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed steel mill cylinder for customers from Finland.

Introduction to steel mill cylinder:

The main role of the steel mill cylinder: the steel mill cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the steel mill cylinder realizes reciprocating motion. The structure of the steel mill cylinder has three categories: piston steel mill cylinder, plunger steel mill cylinder, swing steel mill cylinder, piston steel mill cylinder and plunger steel mill cylinder to achieve reciprocating linear motion, output speed and thrust, swing steel mill cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the steel mill cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The steel mill cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Repair method of small range wear of oil steel mill 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.

The wear of the hard chromium plating layer of the steel mill cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

When the steel mill cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the steel mill cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

Answers to some questions about steel mill cylinder:

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.

What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
