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

stainless steel cylinder are widely used in Tanzania，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed stainless steel cylinder for customers from Tanzania.

Introduction to stainless steel cylinder:

The "O" ring can be used as an auxiliary seal inside the stainless steel cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the stainless steel cylinder, and can be completely sealed.

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.

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.

If the piston rod and stainless steel cylinder are stuck or the stainless steel cylinder is blocked, at this time, no matter how to operate, the stainless steel cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the stainless steel cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about stainless steel cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
