This article mainly introduces:

Dominica hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder

(Dominica series synchronous cylinder,produced by Hebei Hengyu company）

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

Introduction to series synchronous cylinder:

The difference between the plunger series synchronous cylinder and the piston series synchronous cylinder is that the piston in the series synchronous cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type series synchronous cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Before the series synchronous cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

Regular maintenance of the series synchronous cylinder includes: regular tightening, series synchronous cylinder fastening screws and gland screws, series synchronous cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the series synchronous cylinder once a year. Clean regularly, the series synchronous cylinder is cleaned every other year, and the seals are replaced while cleaning.

When the series synchronous cylinder needs to be stored for a period of time, please follow the recommended methods: The series synchronous cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the series synchronous 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 series synchronous cylinder should not be in direct contact with water vapor for a long time. The series synchronous cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the series synchronous 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 series synchronous cylinder Before working, the series synchronous cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the series synchronous 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 series synchronous cylinder:

What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.

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.
