Estonia hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(Estonia single rack cylinder,produced by Hengyu Group）

single rack cylinder are widely used in Estonia，because of powerful torque，simple structure and reliable operation，excellent fatigue and impact resistance.So our company has designed single rack cylinder for customers from Estonia.

Introduction to single rack cylinder:

The single rack cylinder is mainly composed of body, piston, piston rod, single rack cylinder head, single rack cylinder bottom, piston rod head and related auxiliary devices. The piston divides the single rack cylinder into two chambers, and moves reciprocally in the single rack cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the single rack cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the single rack cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the single rack cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the single rack cylinder bottom and the single rack cylinder head is serious, so the buffer deceleration should be set at both ends of the single rack cylinder The working medium of the single rack cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; single rack cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the single rack cylinder: The buffer structure of the single rack cylinder is to prevent the piston from colliding with the single rack cylinder head at the end of the stroke.

When producing oil single rack cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

When installing the single rack cylinder pipe, the pipe should be cleaned after installation, and should not pass through the single rack cylinder block, and the by-pass pipe must be installed in front of the oil port of the single rack cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the single rack cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the single rack cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

When using the single rack cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the single rack cylinder block. If the single rack 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 single rack cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the single rack cylinder, so that the working efficiency of the single rack cylinder is reduced.

Answers to some questions about single rack cylinder:

How to distinguish loader boom and forearm hydraulic cylinder? Is it the upper arm or the lower arm?
The one in the middle that can flip the bucket is the small arm cylinder you say, and the one that lifts the brackets (big arms) on both sides is the big arm cylinder.

What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.
