Principles of choosing a suitable place or warehouse for storing high-precisi...

1. It should be a place of cleanness, smooth drainage of water, and far-away from mine or factory discharging exotic gas or dust. Meanwhile, clear up sundries on the ground and keep the tube clean;

Comparison between processing method of a hydraulic cylinder tube, traditiona...

High-precision tube---compared with that by traditional skiving and rolling, a hydraulic cylinder by cold-drawing is charactered as below

Application of hydraulic cylinder for prevention of cavitation

A hydraulic cylinder can play a roll of preventing cavitation. Although reasons for cavitation maybe different, however, cavitation is preventable providing appropriate measure is taken. In terms of t

Reasons for running instability of honed hydraulic cylinder

1. Air exists in the cylinder, which can cause slide-down and climb-up of the piston when air shrinks and expands. To solve it, check the hydraulic pump, set up the exhaust unit and run the cylinder i

Correct disassembly of hydraulic cylinder rod

A hydraulic cylinder rod device is usually used at operation like lifting, bending, straightening, nobbing, cutting, plug welding, jacking, stretching, dismounting, hole punching, and nobbing of steel

Working principles of sealing parts for pneumatic cylinder bar

1.In order to supplement the size tolerance of groove a hydraulic cylinder barrel owns itself, whatever for the seal or the cylinder barrel, volume production must be under strict request of size tole

Materials for a hydraulic cylinder barrel

1.A cold-drawn or hot-rolled seamless tube is a common rough material for cylinder barrel. The semi-finish already treated by honing or fine machining of interior hole can be easily found in the marke

The common connection types of quenched and tempered rod

1.By bolt The most common and simple connection type currently. But the shortage is that the male thread goes broken easily. To prevent it, measures like locking screw, split pin, thread locker, locki

The causes of pits in the surface of honed tube and solutions

The pits on a Hydraulic Honed Tube looks usually rough and uneven in the surface, in most cases appearing continuously in an area, sometimes partially or periodically. Here are some causes as below, 1

Cautions for installation and disassembly of hydraulic cylinder bar

Before disassemble of a hydraulic cylinder bar, pressure of hydraulic circuit should be first relieved. Otherwise, the hydraulic oil with high-pressure in the circuit will spout out as the connector o

Treatment of defects on the interior wall in Stainless steel honed tubes

The appearance of pits and air holes on the surface of honed tube is specially related to the material itself, which should be avoided. Further treatment should be taken to prevent such defects during

The principles of high-frequencey quenching for a high-frequency quenched pis...

Mostly, when to process a work piece, it should be put under certain conditions, by which means of designed induction, a main technical process of a product forms. A high-frequency quenched piston rod
