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

steel mill cylinder are widely used in Portugal，because of powerful torque，excellent temperature resistance，no transmission clearance.So our company has designed steel mill cylinder for customers from Portugal.

Introduction to steel mill cylinder:

steel mill cylinder installation precautions: Before installing the steel mill cylinder into the system, the parameters on the steel mill cylinder label should be compared with the parameters when ordering. The base of the steel mill cylinder must have sufficient stiffness, otherwise the steel mill cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The scar on the sliding surface of the steel mill cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the steel mill cylinder wall. Therefore, before installation, these scars must be fully repaired.

When the steel mill cylinder is installed, the piston and the steel mill cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the steel mill cylinder head boss is easy to cause scars when it hits the inner surface of the steel mill cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized steel mill cylinders, only careful and careful operation can be avoided.

steel mill cylinder body inspection: The inner surface of the steel mill cylinder and the piston seal are the main factors causing the leakage in the steel mill cylinder, if the steel mill cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the steel mill cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Answers to some questions about steel mill cylinder:

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.

What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.
