Saudi Arabia shearing machine cylinder

(Saudi Arabia shearing machine cylinder,produced by Hebei Hengyu company)

shearing machine cylinder are widely used in Saudi Arabia,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed shearing machine cylinder for customers from Saudi Arabia.

Introduction to shearing machine cylinder:

Do not enter foreign bodies when installing the shearing machine cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

When installing the shearing machine cylinder pipe, the pipe should be cleaned after installation, and should not pass through the shearing machine cylinder block, and the by-pass pipe must be installed in front of the oil port of the shearing machine cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the shearing machine cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the shearing machine 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.

After the shearing machine cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

The shearing machine cylinder is mainly composed of body, piston, piston rod, shearing machine cylinder head, shearing machine cylinder bottom, piston rod head and related auxiliary devices. The piston divides the shearing machine cylinder into two chambers, and moves reciprocally in the shearing machine 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 shearing machine cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the shearing machine 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 shearing machine 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 shearing machine cylinder bottom and the shearing machine cylinder head is serious, so the buffer deceleration should be set at both ends of the shearing machine cylinder The working medium of the shearing machine cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; shearing machine 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 shearing machine cylinder: The buffer structure of the shearing machine cylinder is to prevent the piston from colliding with the shearing machine cylinder head at the end of the stroke.

Answers to some questions about shearing machine cylinder:

What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.
