(Norway stainless steel cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to stainless steel cylinder:

The wear of the hard chromium plating layer of the stainless steel cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Causes and countermeasures of oil stainless steel cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the stainless steel cylinder will lead to premature wear of the piston seal, replace the piston seal; If the stainless steel cylinder is visibly scarred, the stainless steel cylinder must be replaced. It can be pressurized at one end of the stainless steel cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most stainless steel cylinder piston drift may not come from the stainless steel cylinder, the above method to determine the stainless steel cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

stainless steel cylinder body inspection: The inner surface of the stainless steel cylinder and the piston seal are the main factors causing the leakage in the stainless steel cylinder, if the stainless steel cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the stainless steel cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the stainless steel cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Answers to some questions about stainless steel cylinder:

Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
