stainless steel cylinder are widely used in Italy，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 Italy.

Introduction to stainless steel cylinder:

stainless steel cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the stainless steel cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

stainless steel cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

The stainless steel cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure stainless steel cylinder can use 20 steel pipe, and the high pressure stainless steel cylinder can use 45 steel pipe.

When the stainless steel cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the stainless steel cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil stainless steel cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical stainless steel cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the stainless steel cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

Answers to some questions about stainless steel cylinder:

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.
