(Puerto Rico tailboard balance cylinder,produced by Hengyu Hydraulic Co., Ltd）

tailboard balance cylinder are widely used in Puerto Rico，because of no need for deceleration device，long service life，smooth movement.So our company has designed tailboard balance cylinder for customers from Puerto Rico.

Introduction to tailboard balance cylinder:

When using the tailboard balance cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the tailboard balance cylinder block. If the tailboard balance cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the tailboard balance cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the tailboard balance cylinder, so that the working efficiency of the tailboard balance cylinder is reduced.

When installing the tailboard balance cylinder, the axial ends of the tailboard balance cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the tailboard balance cylinder, there is axial expansion. If the two ends of the tailboard balance cylinder are fixed, all parts of the tailboard balance cylinder will be deformed. When disassembling the tailboard balance cylinder, it is strictly forbidden to hammer the tailboard balance cylinder and the piston surface, such as the tailboard balance 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.

Do not enter foreign bodies when installing the tailboard balance cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

Disassembly tailboard balance cylinder: When disassembly tailboard balance cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the tailboard balance cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the tailboard balance cylinder.

Answers to some questions about tailboard balance cylinder:

Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.

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.
