(Korea HSG engineering cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to HSG engineering cylinder:

Regular maintenance of the HSG engineering cylinder includes: regular tightening, HSG engineering cylinder fastening screws and gland screws, HSG engineering 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 HSG engineering cylinder once a year. Clean regularly, the HSG engineering cylinder is cleaned every other year, and the seals are replaced while cleaning.

HSG engineering cylinder can not drive the load troubleshooting: oil pressure is too low. HSG engineering cylinder selection specifications are too small. Leakage in HSG engineering cylinder or associated hydraulic system element.

Causes and countermeasures of oil HSG engineering cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the HSG engineering cylinder will lead to premature wear of the piston seal, replace the piston seal; If the HSG engineering cylinder is visibly scarred, the HSG engineering cylinder must be replaced. It can be pressurized at one end of the HSG engineering cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most HSG engineering cylinder piston drift may not come from the HSG engineering cylinder, the above method to determine the HSG engineering cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

When the HSG engineering cylinder needs to be stored for a period of time, please follow the recommended methods: The HSG engineering cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the HSG engineering 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 HSG engineering cylinder should not be in direct contact with water vapor for a long time. The HSG engineering cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the HSG engineering 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 HSG engineering cylinder Before working, the HSG engineering cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the HSG engineering 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 HSG engineering cylinder:

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.

How to select the 2.5T bearing cylinder and hydraulic pump?
2,5 ton load is not heavy, you can use the rated pressure of 16 mpa gear pump, neither waste nor save cost, load/pressure = cylinder diameter, preset pressure of 8 mpa, 2500 (kg) /80 (bar) =31.25 square centimeters, in the open =63 mm, cylinder diameter can be selected 63 mm, stroke according to the situation, Hydraulic pump select gear pump, if there is a speed requirement, in order to calculate the displacement, the motor power also needs to determine the displacement of the pump to calculate.
