Sri Lanka high pressure cylinder

(Sri Lanka high pressure cylinder,produced by Hengyu Group)

high pressure cylinder are widely used in Sri Lanka,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed high pressure cylinder for customers from Sri Lanka.

Introduction to high pressure cylinder:

high pressure cylinder buffer valve inspection and maintenance: For the valve buffer high pressure cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

high pressure cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

When the high pressure cylinder needs to be stored for a period of time, please follow the recommended methods: The high pressure cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the high pressure 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 high pressure cylinder should not be in direct contact with water vapor for a long time. The high pressure cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the high pressure 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 high pressure cylinder Before working, the high pressure cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the high pressure cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

high pressure cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the high pressure cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

Answers to some questions about high pressure cylinder:

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.

How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
