(Luxembourg supporting cylinder,produced by Hengyu Group）

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

Introduction to supporting cylinder:

Before the supporting cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

The cavitation of the supporting cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the supporting cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

In the process of using the supporting cylinder, sometimes such a problem will occur, the supporting cylinder can not act immediately after the instruction of the supporting cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil supporting cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

When the supporting cylinder is in use, ensure that the supporting cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

Answers to some questions about supporting cylinder:

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking 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.

Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.
