(Slovakia non-standard special type cylinder,produced by Hebei Hengyu company）

non-standard special type cylinder are widely used in Slovakia，because of powerful torque，clever hydraulic energy conversion，no transmission clearance.So our company has designed non-standard special type cylinder for customers from Slovakia.

Introduction to non-standard special type cylinder:

When the non-standard special type cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the non-standard special type cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

non-standard special type cylinder piston rod material introduction: In general, we use 45 steel to produce non-standard special type cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

When the piston speed of the non-standard special type cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the non-standard special type cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

If the non-standard special type cylinder slips or crawls, please check whether there is astringency inside the non-standard special type cylinder, because the internal parts of the non-standard special type cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the non-standard special type cylinder changes with the different stroke position, and the slip or crawl occurs. 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 non-standard special type 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.

Answers to some questions about non-standard special type cylinder:

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.

How to calculate hydraulic cylinder flow?
Effective area of the cylinder x stroke = volume usually in liters. Volume/estimated total travel time (converted to minutes) = oil flow rate.
