(Peru single rack cylinder,produced by Hengyu Hydraulic Co., Ltd）

single rack cylinder are widely used in Peru，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed single rack cylinder for customers from Peru.

Introduction to single rack cylinder:

Because of the slightly complex structure of the buffer single rack cylinder, sometimes there will be problems, such as when the single rack cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

In the case of serious wear on the inner surface of the single rack cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the single rack cylinder manufacturing process for replacement. The single rack cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

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 installing the single rack cylinder, the axial ends of the single rack cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the single rack cylinder, there is axial expansion. If the two ends of the single rack cylinder are fixed, all parts of the single rack cylinder will be deformed. When disassembling the single rack cylinder, it is strictly forbidden to hammer the single rack cylinder and the piston surface, such as the single rack cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about single rack cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.
