(Sri Lanka stern plate hydraulic cylinder,produced by Hebei Hengyu company）

stern plate hydraulic cylinder are widely used in Sri Lanka，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed stern plate hydraulic cylinder for customers from Sri Lanka.

Introduction to stern plate hydraulic cylinder:

If the stern plate hydraulic cylinder slips or crawls, please check whether there is astringency inside the stern plate hydraulic cylinder, because the internal parts of the stern plate hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the stern plate hydraulic cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the stern plate hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

When the initial action of the stern plate hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the stern plate hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

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

The stern plate hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the stern plate hydraulic cylinder should pay attention to: the operation should be as far away from the stern plate hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the stern plate hydraulic cylinder coating. When cleaning the stern plate hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the stern plate hydraulic cylinder when the oil temperature exceeds 70 ° C.

Answers to some questions about stern plate hydraulic cylinder:

What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.

How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
