Tanzania hollow cylinder

(Tanzania hollow cylinder,produced by Hengyu Hydraulic Cylinder Factory)

hollow cylinder are widely used in Tanzania,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed hollow cylinder for customers from Tanzania.

Introduction to hollow cylinder:

When the hollow cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the hollow cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

The piston seal of the hollow cylinder is the main element to prevent leakage in the hollow cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

When using the hollow cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the hollow cylinder block. If the hollow 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 hollow cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the hollow cylinder, so that the working efficiency of the hollow cylinder is reduced.

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

Answers to some questions about hollow cylinder:

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)
