(Colombia servo cylinder,produced by Hengyu Hydraulic Co., Ltd）

servo cylinder are widely used in Colombia，because of excellent fatigue and impact resistance，long service life，simple structure and reliable operation.So our company has designed servo cylinder for customers from Colombia.

Introduction to servo cylinder:

When the servo cylinder is in use, ensure that the servo cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

When installing the servo cylinder, the axial ends of the servo cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the servo cylinder, there is axial expansion. If the two ends of the servo cylinder are fixed, all parts of the servo cylinder will be deformed. When disassembling the servo cylinder, it is strictly forbidden to hammer the servo cylinder and the piston surface, such as the servo 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.

The scar on the sliding surface of the servo cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the servo cylinder wall. Therefore, before installation, these scars must be fully repaired.

servo cylinder piston rod material introduction: In general, we use 45 steel to produce servo cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

Answers to some questions about servo cylinder:

How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.

Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
