Problems solved by technology
If parameters such as the lifting height, speed, and rated load of the elevator are not considered, but the absolute energy consumption of a complete up and down stroke of the elevator is tested randomly, it is obvious that the energy consumption of the elevator with a large lifting height and a large load will definitely be higher. Obviously, this cannot objectively reflect the actual energy consumption level of the elevator, so the absolute energy consumption of these different elevators is not comparable, so the energy consumption of the elevator cannot be used as an indicator for the evaluation of elevator energy efficiency

Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings.
[0038] see Figure 1 to Figure 6 As shown, the present invention provides an elevator energy efficiency test method, wherein the energy efficiency coefficient refers to the ratio of the effective work done by the system to the electric energy consumed. According to this definition, it is assumed that the effective work done by the elevator is W, and the electric energy consumed is E. Converted by unit, the energy efficiency coefficient of the elevator is η=W / (3600·E). Considering heat generation and other energy consumption, the value of η The value range should be between 0 and 1.
[0039] If the effective work W done by the elevator in the above energy efficiency coefficient expression and the electric energy E consumed are reversed, the above energy efficiency coefficient expression becomes another expression, that is, the effective work done by the elevator to tra...

The invention provides an elevator energy efficiency testing method. The elevator energy efficiency testing method comprises the steps that S1, a time interval is set in advance, and a clamp power meter is used for obtaining data of elevator power, cumulative energy consumption and elevator harmonic waves which correspond to each time interval; S2, the cumulative energy consumption under differentoperating conditions is used as a y-axis, and an elevator test load is used as an x-axis to establish a relationship curve diagram, so that a relationship between the total energy consumption of theelevator up and down process and the elevator test load is a quadratic function parabola; S3, a formula 4: E1=EP+(E0-EP)*(Mum-m1)<2> / (Mum)<2> is obtained according to the quadratic function parabola;and S4, if other data of the actual energy consumption of an elevator is to be obtained, the corresponding cumulative energy consumption of the elevator needs to be obtained according to the formula 4. Excess data is not required to be tested in the elevator energy efficiency testing process, and a number of manpower and material resources are saved.
Description
technical field [0001] The invention relates to the technical field of special equipment, in particular to an elevator energy efficiency testing method. Background technique [0002] With the continuous development of modern cities, people's requirements for the convenience, safety and energy saving of elevators are constantly increasing. The energy consumption of elevators is an important indicator for evaluating elevators. Therefore, it is particularly important to study the energy consumption test of elevators. The energy consumption characteristics and usage of the elevator determine the energy consumption level of the elevator. When evaluating and analyzing the energy efficiency of the elevator, the energy consumption of the elevator under a specific working condition cannot be used as an evaluation index. At present, there are many institutions researching the energy consumption of elevators, but the research results are independent and limited. The performance, operat...
