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

steel mill cylinder are widely used in America，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed steel mill cylinder for customers from America.

Introduction to steel mill cylinder:

The steel mill cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the steel mill cylinder should pay attention to: the operation should be as far away from the steel mill cylinder as possible, to avoid falling objects, knocking, rubbing the steel mill cylinder coating. When cleaning the steel mill cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the steel mill cylinder when the oil temperature exceeds 70 ° C.

Regular maintenance of the steel mill cylinder includes: regular tightening, steel mill cylinder fastening screws and gland screws, steel mill cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the steel mill cylinder once a year. Clean regularly, the steel mill cylinder is cleaned every other year, and the seals are replaced while cleaning.

steel mill cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the steel mill cylinder head itself is the guide sleeve of the piston rod, the steel mill 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 steel mill cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The piston rod and guide sleeve function of the steel mill cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

Answers to some questions about steel mill cylinder:

Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
