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

Introduction to stainless steel cylinder:

The difference between the plunger stainless steel cylinder and the piston stainless steel cylinder is that the piston in the stainless steel 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 stainless steel cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

The pressure of the sliding surface of the stainless steel cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the stainless steel cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

When the stainless steel cylinder needs to be stored for a period of time, please follow the recommended methods: The stainless steel cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the stainless steel 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 stainless steel cylinder should not be in direct contact with water vapor for a long time. The stainless steel cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the stainless steel 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 stainless steel cylinder Before working, the stainless steel cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the stainless steel cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

stainless steel cylinders in series, parallel and series parallel. Series: In the stainless steel cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the stainless steel cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the stainless steel cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the stainless steel cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

Answers to some questions about stainless steel cylinder:

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
