Hungary rack cylinder

(Hungary rack cylinder,produced by Hebei Hengyu company)

rack cylinder are widely used in Hungary,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed rack cylinder for customers from Hungary.

Introduction to rack cylinder:

When the rack cylinder is installed, the piston and the rack 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 rack cylinder head boss is easy to cause scars when it hits the inner surface of the rack 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 rack cylinders, only careful and careful operation can be avoided.

Improve the service life of the rack 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 rack cylinder (such as the rack 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 rack 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 rack cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single rack cylinder exhaust.

When the hydraulic oil is not pumped into the rack cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the rack cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

rack cylinder use should try to avoid sealing belt into the rack cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the rack cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the rack cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

Answers to some questions about rack cylinder:

What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.

How to distinguish loader boom and forearm hydraulic cylinder? Is it the upper arm or the lower arm?
The one in the middle that can flip the bucket is the small arm cylinder you say, and the one that lifts the brackets (big arms) on both sides is the big arm cylinder.
