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

steel mill cylinder are widely used in Japan,because of long service life,smooth movement,high work efficiency.So our company has designed steel mill cylinder for customers from Japan.

Introduction to steel mill cylinder:

If it is found that the steel mill cylinder lubrication is poor or the steel mill cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the steel mill cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the steel mill cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the steel mill cylinder center line. In this way, when the piston works in the steel mill cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the steel mill cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the steel mill cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

The steel mill cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the steel mill cylinder, bite. Elimination method: When installing the steel mill cylinder, ensure that the axis position of the steel mill cylinder is consistent with the direction of movement; Make the load borne by the steel mill cylinder as far as possible through the steel mill cylinder axis, to avoid the phenomenon of eccentricity.

When using the steel mill cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the steel mill cylinder block. If the steel mill cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the steel mill cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the steel mill cylinder, so that the working efficiency of the steel mill cylinder is reduced.

Answers to some questions about steel mill cylinder:

How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.

What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.
