Elevator energy efficiency method of measurement and survey meter based on difference mass velocity integral method
Technical field
The present invention relates to machine efficiency measurement technique, relate in particular to a kind of elevator energy efficiency method of measurement and survey meter based on difference mass velocity integral method.
Background technology
Elevator is as the part of architectural energy consumption, and its energy consumption issues is by extensive concern, and China is nearly to use 1,000,000 ones in elevator, and elevator has become the important object of energy-saving and emission-reduction.By employing new technology, can significantly reduce the use energy consumption of elevator, but the China and even the whole world all there is not unified elevator energy efficiency definition, do not have the elevator energy efficiency method of measurement as national standard yet.Because the standard omission causes elevator energy-saving reduction of discharging work large tracts of land to carry out, also be unfavorable for guiding elevator manufacturer to adopt new and high technology to improve the efficiency of manufacturing elevator, eliminate backward, inefficient elevator.
The factor that influences elevator energy efficiency is many-sided, and elevator speed, different its efficiencies of performance load are difference also, and promptly elevator energy efficiency essence changes with the elevator condition of service.The definition of elevator energy efficiency is to set up the electrical usage efficient that a generally acknowledged yardstick is weighed the different elevators of sign with measuring purpose, so measure the key of elevator energy efficiency is rational method of measurement of definition, get rid of the various factors that influence elevator energy efficiency to the interference that result of a measurement caused, make result of a measurement have comparability.
The elevator energy efficiency method of measurement that has proposed at present or too simple such as causes at the bottom of the measuring accuracy not approved by industry at a series of defectives, or tests loaded down with trivial details with high costs and can't large tracts of land promote the use of.Particularly the simulated condition method measured of elevator energy efficiency needs move into and the cooresponding counterweight of 25%, 50%, 75%, 100% rated load toward lift car respectively, in the elevator field conduct time-consuming consumption power of getting up.
Elevator is a special equipment, must not damage the safety of elevator to the measurement of elevator energy efficiency, so method of measurement is preferably contactless, does not relate to elevator control cabinet in-to-in signal, could guarantee the intrinsic safety of method of measurement like this.
The elevator energy efficiency survey meter has proposed high requirement to the resolution and the precision of measuring instrument, if allow elevator come and go repeatedly operation by test run work collection of illustrative plates, must extend the test duration, increased testing cost to causing unnecessary economic loss owner with elevator, so preferably reduce the elevator number of run during test, the prerequisite that reduces the test run number of times is to have survey precision to guarantee.
