The size and the shape of the hollow passage and the special space are determined through calculation. The reciprocating compressor damping energy-saving device is connected with an inlet-outlet pipe of a reciprocating compressor; pulse dynamic energy is converted to static pressure energy through a peculiar flowing structure so as to prevent the transmission of the pulse pressure wave, thereby finally realizing the damping and energy conservation.
Description
Affiliated technical field
The invention belongs to energy-conservation and the prevention technique field, relate generally to a kind of shock absorption energy-saving device of reciprocating compressor.
Background technique
The work characteristics of reciprocal compressor be inhale, blast air is periodically/and or intermittence, so the flow parameter of air-flow (as pressure, speed, density) is periodic variation with position and time.This phenomenon is called gas.Gas influences the Economy and the reliability of compressor significantly: cause the increase or the minimizing of reciprocating compressor air displacement; Cause that the extra wasted work of reciprocating compressor increases; The work of air valve is worsened; Piping, cylinder body vibrating fatigue are destroyed; Cause noise circumstance pollution etc.
The existence of pulse pneumatic always makes the power loss of reciprocal compressor increase, and promptly useful horsepower reduces.Gas in the reciprocal compressor aspirating air pipe may make the indicated power of compressor increase, and indicated power is reduced.Pressure pulsation between arbitrary number of level is much stronger to the influence of power loss than pressure pulsation in the aspirating air pipe to the influence of compressor horsepower loss.Gas in the exhaust duct always makes the indicated power of compressor increase, particularly when resonance takes place in gas column in the exhaust duct, the power that compressor consumed increases greatly, at this moment, all other losses, comprise that pipe resistance loss and air valve loss all seem insignificant, put down in writing according to relevant document: the power loss that the gas in the exhaust duct consumes can account for 40% of total output.
Therefore, remove or slacken pulse pneumatic intensity effectively, not only can eliminate the pipe and equipment vibration effectively, and can increase the Economy and the Security of compressor assembly, improve the device operant level.Have tangible economic benefit and social benefit.
Summary of the invention
The objective of the invention is to propose a kind of shock absorption energy-saving device of reciprocating compressor, it is by the Diffuser pulse pneumatic kinetic energy that dissipates effectively, make it change static energy into, in addition by changing the pressure wave transmission characteristics of gas circuit in piping and the accessory thereof, and reduce its intensity, thereby reach energy-conservation and purpose weakening.
Device proposed by the invention mainly is made up of shell (4), internals and air-flow particular space (7); It is characterized in that: described internals is made of changeover portion (2), Diffuser (3) and center cone (6); Form air-flow particular space (7) between internals and the shell (4); Air current flow spatial communication between the outlet of Diffuser (3) and internals, the shell; The sectional shape one of described Diffuser by straightway or circular arc line segment or parabolic segment or hyperbolic line segment or launch periodic space plane curvilinear structures that line segment forms divide inside and outside two-layer difference along the circumferential direction, or along quadrilateral, triangle and regular polygon direction extension arrangement thereof, the plane curve of a multiply connected region of formation; The axial direction of this sectional shape along external casing stretched, form the hollow channel of the complicated shape of both ends open.The size of this hollow channel and air-flow particular space (7) and shape are calculated by mechanics of viscous fluids, aeroacoustics and are determined.The inlet/outlet air-flow of reciprocating compressor is entered by the suction port (1) of this device, the changeover portion (2) of flowing through is flowed out by Diffuser (3), enter air-flow particular space (7), form the complicated vortex system structure that flows, pulse pneumatic is become steady air flow, with the kinetic energy static energy that changes into as much as possible, flow out by air outlet (5) then.
Sectional dimension at each axial position of Diffuser equates with former busbar cross-section size, the contraction of equal proportion or the expansion of equal proportion.
The center cone that has a size coupling Diffuser in the central position of Diffuser.The shape of center cone is to be cone at axial two ends, is cubical assemblying body in the centre, or cubical assemblying body in the middle of removing.
The shape of center cone also can be to be cone at axial two ends, is cylindrical assemblying body in the centre, or removes the assemblying body of mediate cylindrical.
