(Japan disc spring hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

disc spring hydraulic cylinder are widely used in Japan，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed disc spring hydraulic cylinder for customers from Japan.

Introduction to disc spring hydraulic cylinder:

In the case of serious wear on the inner surface of the disc spring hydraulic cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the disc spring hydraulic cylinder manufacturing process for replacement. The disc spring hydraulic cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

If the disc spring hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the disc spring hydraulic cylinder. The internal parts of the disc spring hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the disc spring hydraulic cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the disc spring hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the disc spring hydraulic cylinder bore processing is out of whack. Because the piston and disc spring hydraulic cylinder, guide rail and piston rod are relative If the disc spring hydraulic cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling disc spring hydraulic cylinder weight composition and calculation. The weight of the disc spring hydraulic cylinder is composed of the disc spring hydraulic cylinder diameter, the outer diameter and weight of the disc spring hydraulic cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

The advantages and disadvantages of the disc spring hydraulic cylinder: the surface of the disc spring hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the disc spring hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

The disc spring hydraulic cylinder should be used correctly and maintained regularly. The disc spring hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the disc spring hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

Answers to some questions about disc spring hydraulic cylinder:

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.
