Finland hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder

(Finland series synchronous cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to series synchronous cylinder:

The material of the sliding part of the series synchronous cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

The definition of the minimum stable speed refers to the minimum movement speed of the series synchronous cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the series synchronous cylinder that undertakes different work has different requirements for the minimum stable speed.

series synchronous cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the series synchronous cylinder head itself is the guide sleeve of the piston rod, the series synchronous cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the series synchronous cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The wear of the hard chromium plating layer of the series synchronous 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.

Answers to some questions about series synchronous cylinder:

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.

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.
