(Uruguay pressure retaining cylinder,produced by Hengyu Group）

pressure retaining cylinder are widely used in Uruguay，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed pressure retaining cylinder for customers from Uruguay.

Introduction to pressure retaining cylinder:

pressure retaining cylinder and hydraulic station selection: Select the type and structure of the pressure retaining cylinder according to the operation requirements of the main engine. According to the external load force borne by the pressure retaining cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the pressure retaining cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the pressure retaining cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the pressure retaining cylinder, the diameter of the piston and the piston rod.

There are some honeycomb holes in the inner wall of the pressure retaining cylinder, piston or piston rod surface. How is this formed? When we repair the pressure retaining cylinder, we can see that there are some honeycomb holes on the inner wall of the pressure retaining cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the pressure retaining cylinder is targeted to prevent. Is very necessary.

When installing the pressure retaining cylinder, the axial ends of the pressure retaining cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the pressure retaining cylinder, there is axial expansion. If the two ends of the pressure retaining cylinder are fixed, all parts of the pressure retaining cylinder will be deformed. When disassembling the pressure retaining cylinder, it is strictly forbidden to hammer the pressure retaining cylinder and the piston surface, such as the pressure retaining 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 daily inspection of the pressure retaining cylinder includes: checking the connection of the pressure retaining cylinder and the pipe joint for leaks. Check the pressure retaining cylinder rod for leaks. Check the pressure retaining cylinder connection for leaks. When the pressure retaining cylinder moves, the work is normal and smooth. Whether the pressure retaining cylinder has internal leakage.

Answers to some questions about pressure retaining cylinder:

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation 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 valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
