steering cylinder are widely used in France，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed steering cylinder for customers from France.

Introduction to steering cylinder:

If the piston rod and steering cylinder are stuck or the steering cylinder is blocked, at this time, no matter how to operate, the steering 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 steering cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

If the steering cylinder slips or crawls, please check whether there is astringency inside the steering cylinder, because the internal parts of the steering 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 steering 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 steering 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.

The steering cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

When the steering cylinder needs to be stored for a period of time, please follow the recommended methods: The steering cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the steering cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil steering cylinder should not be in direct contact with water vapor for a long time. The steering cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the steering cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the steering cylinder Before working, the steering cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the steering cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about steering cylinder:

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
