(Bulgaria yg series hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

yg series hydraulic cylinder are widely used in Bulgaria，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed yg series hydraulic cylinder for customers from Bulgaria.

Introduction to yg series hydraulic cylinder:

yg series hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

The piston rod of the yg series hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Regular maintenance of the yg series hydraulic cylinder includes: regular tightening, yg series hydraulic cylinder fastening screws and gland screws, yg series hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the yg series hydraulic cylinder once a year. Clean regularly, the yg series hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.

When the yg series hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The yg series hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the yg series hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil yg series hydraulic cylinder should not be in direct contact with water vapor for a long time. The yg series hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the yg series hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the yg series hydraulic cylinder Before working, the yg series hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the yg series hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about yg series hydraulic cylinder:

What is the cause of the deep scratch of the cylinder?
The following reasons can cause the cylinder to be scratched. 1: Hydraulic oil containing particulate impurities into the hydraulic cylinder, these particulate impurities stuck between the piston rod and the guide ring (or stuck between the piston and the inner wall of the cylinder), when the piston movement in the cylinder will scratch the piston rod, the phenomenon of the inner wall of the cylinder, the more particles, the larger the scratch marks the deeper and more obvious. 2: The body of the cylinder itself. Due to assembly or design reasons, the coaxial error between the piston rod, piston, cylinder, guide ring and other parts is too large, or the cylinder, piston rod straightness error is too large, so that the piston rod and the guide ring interference between the cylinder, this mechanical interference will certainly lose the piston rod or cylinder wall.

How to exhaust hydraulic cylinder?
Exhaust: The hydraulic system generally does not have exhaust, the use of the tank can exhaust, the oil operation will bring the gas back to the tank, and the tank can be communicated with the atmosphere. The gas will escape from the oil.
