(Argentina self-locking hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

self-locking hydraulic cylinder are widely used in Argentina，because of long service life，smooth movement，high work efficiency.So our company has designed self-locking hydraulic cylinder for customers from Argentina.

Introduction to self-locking hydraulic cylinder:

In the process of using the self-locking hydraulic cylinder, sometimes such a problem will occur, the self-locking hydraulic cylinder can not act immediately after the instruction of the self-locking hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil self-locking hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

The self-locking hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure self-locking hydraulic cylinder can use 20 steel pipe, and the high pressure self-locking hydraulic cylinder can use 45 steel pipe.

The material of the sliding part of the self-locking hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Do not enter foreign bodies when installing the self-locking hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

Answers to some questions about self-locking hydraulic cylinder:

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.
