(Germany steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to steel mill cylinder:

Repair method of small range wear of oil steel mill 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 viscosity of the working oil used in the steel mill cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

If the steel mill cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

The internal leakage of the steel mill cylinder is an important indicator to measure the quality of the steel mill cylinder: the internal leakage of the steel mill cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the steel mill cylinder, so that the steel mill cylinder can not accurately and stably stop in a certain position of the steel mill cylinder, so it is one of the main indicators of the steel mill cylinder.

Answers to some questions about steel mill cylinder:

Where is the cylinder used? What is it used for? Can it be used in cars?
Cylinders can be used as actuator in hydraulic system. Such as hydraulic jacks, dump truck box lifting device, dodging (snow) machine loader bucket lifting device. Hydraulic cylinders are also widely used in car cranes. It's all about cars.

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.
