Abstract
A kind of method of test centrifugal machine overall dynamic-balance, be to have adopted by non-contact vortex type detecting polarization instrument, resolve transducer and luminous point vector wattmeter constitutes complete test macro, this system can directly test out the size and the phase place of bowl complete machine amount of unbalance, and the measuring accuracy height, easy to operate.
Description
The present invention is the improvement that belongs to centrifugal machine dynamic balancing measurement method.
Hydro-extractor is one of major equipment of Separation of Solid and Liquid, and its vibration is individual very important problem.The reason that causes the hydro-extractor vibration mainly is the mass unbalance of its rotary drum and annex.In order to eliminate this vibration that produces because of mass unbalance, usually the method that adopts is in advance in the enterprising action balance test of equilibrator with rotary drum, though this kind method can be eliminated amount of unbalance to a certain extent, but rotary drum and the annex finished after the transient equilibrium need be assembled into machine, and this is avoided complete machine to produce new mass unbalance and cause vibration with regard to being difficult to.Therefore directly test centrifugal machine in working order following transient equilibrium comparable on dynamic balancing machine the dynamically balanced precision height of test rotary drum, the present invention has adopted one to overlap complete test macro exactly from this purpose, has realized the system test transient equilibrium.
Fig. 1 is the test unit of test overall dynamic-balance.Wherein 1 is non-contact vortex type detecting polarization instrument; The 2nd, resolve transducer; The 3rd, luminous point vector wattmeter.
After the amount of unbalance of complete machine rotation rotary drum is measured by non-contact vortex type detecting polarization instrument, flow to then and resolve transducer, this can reduce vialog and number of sensors, and can eliminate same place two measuring error that sensor brought are installed.Deliver to luminous point vector wattmeter by the signal that resolves transducer output, the electrical system of this luminous point vector wattmeter has been simulated an electric standard rotor, can solve to demarcate unbalanced size and proofread and correct initial phase.Therefore the luminous point system directly can demonstrate the size and the phase place of rotary drum amount of unbalance on the polar coordinates screen.
The two correction sides system test dynamic balance method that the present invention adopts has measuring accuracy height, advantage such as easy to operate.
Table 1 is to adopt method of testing of the present invention that SS-800 type hydro-extractor system is carried out the dynamic balancing measurement result data.
