Slovenia tension cylinder

(Slovenia tension cylinder,produced by Hengyu Hydraulic Cylinder Factory)

tension cylinder are widely used in Slovenia,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed tension cylinder for customers from Slovenia.

Introduction to tension cylinder:

Repair method of small range wear of oil tension cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

The main role of the tension cylinder: the tension 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 tension cylinder realizes reciprocating motion. The structure of the tension cylinder has three categories: piston tension cylinder, plunger tension cylinder, swing tension cylinder, piston tension cylinder and plunger tension cylinder to achieve reciprocating linear motion, output speed and thrust, swing tension cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the tension cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The tension cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

The tension cylinder should be vented: when the tension cylinder is installed or parked for a long time to work again, the air will penetrate into the tension cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the tension cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the tension cylinder, the oil is best entered and discharged from the highest point of the tension cylinder. tension cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Classification of tension cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

Answers to some questions about tension 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.

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
