France hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(France single rack cylinder,produced by Hebei Hengyu company）

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

Introduction to single rack cylinder:

The difference between the plunger single rack cylinder and the piston single rack cylinder is that the piston in the single rack cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type single rack cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

single rack cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the single rack cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the single rack cylinder. c. The single rack cylinder seal is extruded, if the O-ring is obviously extruded at the single rack cylinder seal, replace the single rack cylinder seal.

When the single rack cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the single rack cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

The daily inspection of the single rack cylinder includes: checking the connection of the single rack cylinder and the pipe joint for leaks. Check the single rack cylinder rod for leaks. Check the single rack cylinder connection for leaks. When the single rack cylinder moves, the work is normal and smooth. Whether the single rack cylinder has internal leakage.

Answers to some questions about single rack cylinder:

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.
