(Nepal stainless steel cylinder,produced by Hebei Hengyu company）

stainless steel cylinder are widely used in Nepal，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed stainless steel cylinder for customers from Nepal.

Introduction to stainless steel cylinder:

When the hydraulic oil is not pumped into the stainless steel cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the stainless steel cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

Under normal circumstances, the stainless steel cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the stainless steel cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the stainless steel cylinder and the end cover, the piston and the piston rod, the piston and the stainless steel cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the stainless steel cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

The scar on the sliding surface of the stainless steel cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the stainless steel cylinder wall. Therefore, before installation, these scars must be fully repaired.

When installing the stainless steel cylinder, the axial ends of the stainless steel cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the stainless steel cylinder, there is axial expansion. If the two ends of the stainless steel cylinder are fixed, all parts of the stainless steel cylinder will be deformed. When disassembling the stainless steel cylinder, it is strictly forbidden to hammer the stainless steel cylinder and the piston surface, such as the stainless steel cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about stainless steel cylinder:

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.

How does the cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, the executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, the control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, the auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
