(Uzbekistan folding machine cylinder,produced by Hebei Hengyu company）

folding machine cylinder are widely used in Uzbekistan，because of powerful torque，clever hydraulic energy conversion，high work efficiency.So our company has designed folding machine cylinder for customers from Uzbekistan.

Introduction to folding machine cylinder:

folding machine cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the folding machine cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the folding machine cylinder. c. The folding machine cylinder seal is extruded, if the O-ring is obviously extruded at the folding machine cylinder seal, replace the folding machine cylinder seal.

The scar on the sliding surface of the folding machine 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 folding machine cylinder wall. Therefore, before installation, these scars must be fully repaired.

The commonly used buffer structure of the folding machine cylinder is composed of a piston boss and a folding machine cylinder head groove. When the piston moves close to the folding machine cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

The machining accuracy of the folding machine cylinder depends on the level of equipment, production technology and testing means. folding machine cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Answers to some questions about folding machine 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.

What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.
