(Burma hydraulic engineering cylinder,produced by Hebei Hengyu company）

hydraulic engineering cylinder are widely used in Burma，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed hydraulic engineering cylinder for customers from Burma.

Introduction to hydraulic engineering cylinder:

The difference between the plunger hydraulic engineering cylinder and the piston hydraulic engineering cylinder is that the piston in the hydraulic engineering cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type hydraulic engineering cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the hydraulic engineering cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

The hydraulic engineering cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic engineering cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The hydraulic engineering cylinder is basically composed of hydraulic engineering cylinder and hydraulic engineering cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

The main role of the hydraulic engineering cylinder: the hydraulic engineering cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the hydraulic engineering cylinder realizes reciprocating motion. The structure of the hydraulic engineering cylinder has three categories: piston hydraulic engineering cylinder, plunger hydraulic engineering cylinder, swing hydraulic engineering cylinder, piston hydraulic engineering cylinder and plunger hydraulic engineering cylinder to achieve reciprocating linear motion, output speed and thrust, swing hydraulic engineering cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the hydraulic engineering cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The hydraulic engineering cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Answers to some questions about hydraulic engineering cylinder:

How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.
