(Ireland rack cylinder,produced by Hengyu Hydraulic Cylinder Factory）
rack cylinder are widely used in Ireland，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed rack cylinder for customers from Ireland.
The rack cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure rack cylinder can use 20 steel pipe, and the high pressure rack cylinder can use 45 steel pipe.
After chrome plating of the piston rod of the rack cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
rack cylinder piston rod material introduction: In general, we use 45 steel to produce rack 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.
The main role of the rack cylinder: the rack 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 rack cylinder realizes reciprocating motion. The structure of the rack cylinder has three categories: piston rack cylinder, plunger rack cylinder, swing rack cylinder, piston rack cylinder and plunger rack cylinder to achieve reciprocating linear motion, output speed and thrust, swing rack cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the rack cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The rack cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.
What size of hydraulic cylinder is needed for 200 tons pressure? The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate by the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the pressure level P (unit MPa) when working, then the thrust of the cylinder F push =3.14*R*R*P (unit N) the pull of the cylinder F pull =3.14* (R* R-R *R) *P (unit N) 100 tons of the cylinder, System pressure 16Mpa.
