(Poland tailboard balance cylinder,produced by Hengyu Hydraulic Cylinder Factory）

tailboard balance cylinder are widely used in Poland，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed tailboard balance cylinder for customers from Poland.

Introduction to tailboard balance cylinder:

When purchasing the tailboard balance cylinder, try to clarify the following parameters of the tailboard balance cylinder: A. tailboard balance cylinder diameter, rod diameter, stroke; B. Working pressure or tailboard balance cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right tailboard balance cylinder type can be found accurately and quickly.

If the piston rod and tailboard balance cylinder are stuck or the tailboard balance cylinder is blocked, at this time, no matter how to operate, the tailboard balance cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the tailboard balance cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

tailboard balance cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

The commonly used buffer structure of the tailboard balance cylinder is composed of a piston boss and a tailboard balance cylinder head groove. When the piston moves close to the tailboard balance cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Answers to some questions about tailboard balance cylinder:

How to select the propulsion cylinder according to the shield attitude, cylinder stroke, shield tail clearance and other factors?
Generally, the shield machine will be equipped with the corresponding cylinder. Soil pressure balancing machine, mud water balancing machine have the corresponding cylinder, there will be no insufficient cylinder force. In the jacking process of the pipe jacking machine, there are certain requirements for the jacking force of the cylinder.

In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
