steel mill cylinder are widely used in Holland，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed steel mill cylinder for customers from Holland.

Introduction to steel mill cylinder:

When the hydraulic oil is not pumped into the steel mill cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the steel mill cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

If the piston rod and steel mill cylinder are stuck or the steel mill cylinder is blocked, at this time, no matter how to operate, the steel mill cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the steel mill cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

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.

In order to ensure the service life of the steel mill cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

Answers to some questions about steel mill cylinder:

How does the clamping cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, The executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, The control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, The auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.
