Hydraulic damper performance characteristics and application fields

Abstract: Hydraulic damper is a kind of speed sensitive reaction vibration control device, its performance characteristics are controlled friction resistance small, long service lives, high temperature resistant etc.

 

   Damper is to provide motion resistance, energy depletion movement of the device. Now in PURROS briefly introduce hydraulic damper characteristics.
1, fast dynamic response; resistance is big, and the dynamic response time is short.
2, controlled friction resistance small; frictional resistance is small, generally less than the rated load 1%-2%.
3, swing angles; the head, the tail is hinged joint bearing, allowing the swing angle of ± 6.
4, long service lives; using special hydraulic oil and sealing medium, stable performance, long service life.
5, high temperature resistant; Can work continuously under a temperature of 93℃, the short-time stability can be as high as 148℃.
6, anti-corrosion performance is good; all material is employed high quality material. Anti-corrosion performance is excellent.
7, compact structures and reasonable stress; compact structure and showed a symmetrical structure, small installation space, forces more reasonable.
   Hydraulic damper is a kind of speed sensitive reaction vibration control device; hydraulic damper is mainly suitable for nuclear power plants, power plants, chemical plants, steel mills etc pipeline and equipment vibration resistance. Often used to control the impact of the fluid turbulence of piping vibration and earthquake vibration; Hydraulic damper for low- frequency amplitude -frequency or high amplitude vibration can’t be effectively controlled, drilling power head of the appropriate use spring shock absorber.

Automatic feed drilling power head main structure analysis

Abstract: With the rapid development of science and technology and the need for large-scale industrial production. New electric, pneumatic automatic feed drilling has become a guarantee accuracy of product processing, reduce production costs and improve labor productivity and competitiveness of enterprises is one of the key measures.

 

  Power head is an important power of modular machine tool parts, their quality and performance of the fit and unfit quality directly affect the whole machine tools performance good or bad, but in general, in the design of modular machine tool power head can only provide the main movement, its feed movement is made with matching hydraulic or mechanical sliding table, this is for modular machine tool design and manufacturing has brought great difficulties. To this end, we provide a new type of electric, pneumatic automatic feed drilling power.
  The following is PURROS Company automatic feed drilling head main structure analysis:
(1) as one of the important power components of combination machine tools, electrical, pneumatic, automatic feed drilling power head has small volume, light weight, compact structure, wide practical level, and the advantages of combination and changeful, can according to the needs of users into various forms of combination machine tools.
(2) electric, pneumatic automatic feed drilling power head rotation movement of the (primary motion) using direct drive motor through the synchronous belt, the feed movement using compressed air as power source, realize the spindle “fast forward, the labor into, fast rewind” automatic cycle, feed movement adopts hydraulic damping, feed speed stepless adjustable, feeding schedule continuously adjustable, drilling big power, can also drive more than the root auger shaft work.
(3) Electrical, pneumatic, automatic feed drilling head is a kind of set power head primary motion, feed movement and the main control system in the integration of high-tech products, is the machine, electricity, gas, hydraulic damper fluid technologies integrated application of the results.
