Description
Technical field
The present invention relates to the pipe clamp of a kind of fluid pressure line.
Background technology
Pipeline as a kind of means of transportation of fluid and carrier, be widely used in oil, chemical industry, plumbing with
And the every field such as Aeronautics and Astronautics, automobile.In fluid system, due to the pumping source such as hydraulic pump, water pump
Architectural feature, the compressibility of fluid and control valve are turned on and off fluid course frequently, can not keep away
That exempts from causes flow pulsation and impact, flow pulsation and impact act on pipeline after by cause pipeline vibration and
Noise.When flow pulsation frequency is overlapping with tubing natural frequency, pipe vibration can be abnormal violent, i.e.
Produce resonance, cause system cisco unity malfunction, produce noise, even cause the rupturing of pipeline, medium is let out
Leakage, accidents caused.Additionally, the vibration of plant equipment is delivered to the danger caused on pipeline by mechanical system
Evil, is also inevitable.These are particularly evident in large scale pipeline system.
At present, control pipe vibration be broadly divided into actively control and passively control two ways.Due to actively control
System processed needs to introduce external power supply, and system design is complex, and according to detection pulsation or pipe vibration
Carry out vibration control and the most usually have delayed, therefore mostly use passive control methods.And passively control mainly have two
Planting realization means, one is the impact weakening vibration source, and being disinthibited by the structural parameters of amendment power source, it flows
Amount is pulsed or mechanical vibration source uses vibration isolation measure, such as, add accumulator at hydraulic pump outlet and reduce power
The fluctuation of source output, at hydraulic pump outlet, the mode such as one section of flexible pipe is installed；Two is the impedance adjusting tubing,
Change line size or layout of beam line, make tubing natural frequency away from excited frequency.Although passively controlling
It is difficult to weakening in the range of bigger frequency range, but controls need not the outside energy that provides, and structure letter due to passive
It is single, it is easy to accomplish, reliability is high, therefore is widely adopted.
Pipe clamp is the auxiliary element that pipe vibration passively controls necessity, is mainly used in pipeline location and fixes, with
Time also act as absorb vibration effect.But, at present conventional pipe clamp weakening is contacting at pipe clamp and pipeline
One or more layers elastomeric material is added in face, and weakening range is little, weakening DeGrain, and in reality
Tubing in, pipe clamp is screwed by bolt and is fixed, along with pipe clamp in tubing long time
Between work, due to the vibration of pipeline, the bolt looseness of pipe clamp or thread damage all can make the clamping of pipe clamp
Power reduces, and makes the stress of pipeline and the natural frequency etc. of pipeline all change, thus reduces system
Reliability, the most accidents caused.
