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

Introduction to metallurgical cylinder:

When installing the metallurgical cylinder pipe, the pipe should be cleaned after installation, and should not pass through the metallurgical cylinder block, and the by-pass pipe must be installed in front of the oil port of the metallurgical cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the metallurgical cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the metallurgical cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

Improve the service life of the metallurgical cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the metallurgical cylinder (such as the metallurgical cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the metallurgical cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the metallurgical cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single metallurgical cylinder exhaust.

Piston metallurgical cylinder is widely used in hydraulic transmission. When the metallurgical cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the metallurgical cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the metallurgical cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

The viscosity of the working oil used in the metallurgical 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.

Answers to some questions about metallurgical cylinder:

When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.

How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself 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.
