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

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

Introduction to stainless steel cylinder:

The body of the stainless steel cylinder on the processing process requirements: the body of the stainless steel cylinder is an important and essential part of the stainless steel cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the stainless steel cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

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.

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.

When the stainless steel cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the stainless steel cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the stainless steel cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the stainless steel cylinder can meet the requirements by grinding. However, the life and reliability of this repair stainless steel cylinder are not high.

Answers to some questions about stainless steel cylinder:

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.

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.
