200 ton hydraulic cylinder

(200 ton hydraulic cylinder,produced by Hengyu Group）

200 ton hydraulic cylinder are widely used ，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed 200 ton hydraulic cylinder for our customers.

Introduction to 200 ton hydraulic cylinder:

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular 200 ton hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

When the 200 ton hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the 200 ton hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the 200 ton hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

When the 200 ton hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The 200 ton hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the 200 ton 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 200 ton hydraulic cylinder should not be in direct contact with water vapor for a long time. The 200 ton hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the 200 ton 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 200 ton hydraulic cylinder Before working, the 200 ton hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the 200 ton 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.

When installing the 200 ton hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the 200 ton hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the 200 ton hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the 200 ton hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the 200 ton hydraulic 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.

Answers to some questions about 200 ton hydraulic cylinder:

CNC lathe rotary cylinder oil leakage and treatment methods
Oil leakage often occurs when the cylinder (especially the hollow cylinder) of the CNC lathe is installed. First check the cylinder yaw, be sure to reach or close to the required value, generally the cylinder requires the outer beat within 1 wire. Otherwise, too much beating is sure to leak oil. Then check whether the tubing is smoothly downward at a certain Angle, and can not bend. Look at the pipe outlet can not go into the oil level, to a little higher. Otherwise, there's back pressure and it's gonna leak.

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.
