(Ethiopia drilling truck cylinder,produced by Hengyu Hydraulic Cylinder Factory）

drilling truck cylinder are widely used in Ethiopia，because of no need for deceleration device，long service life，smooth movement.So our company has designed drilling truck cylinder for customers from Ethiopia.

Introduction to drilling truck cylinder:

If the seal of the drilling truck cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

When using the drilling truck cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the drilling truck cylinder block. If the drilling truck cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the drilling truck cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the drilling truck cylinder, so that the working efficiency of the drilling truck cylinder is reduced.

If the piston rod and drilling truck cylinder are stuck or the drilling truck cylinder is blocked, at this time, no matter how to operate, the drilling truck cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the drilling truck cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The method of sleeve drilling truck cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the drilling truck cylinder can be significantly improved by rolling in the finishing of the inner holes of the drilling truck cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

Answers to some questions about drilling truck cylinder:

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.

Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.
