Description

technical field [0001] The invention relates to a detection and analysis device, in particular to a detection and analysis device for the power efficiency of an electric forklift. Background technique [0002] Due to the characteristics of environmental protection and energy saving, electric forklifts are more and more widely used; in order to reduce the energy loss of electric forklifts and improve their performance, in the process of research and development, production and use, the power efficiency of each energy transfer unit of electric forklifts is tested. And analysis is very necessary; the current detection device usually has the following shortcomings: it can only detect the power of one or several units in the energy transmission process of the electric forklift, for example, some devices can only measure the power of the motor but not the hydraulic power; Simultaneous measurement of all key nodes in the energy transfer process; only physical quantities (voltage, c...

[0002] Due to the characteristics of environmental protection and energy saving, electric forklifts are more and more widely used; in order to reduce the energy loss of electric forklifts and improve their performance, in the process of research and development, production and use, the power efficiency of each energy transfer unit of electric forklifts is tested. And analysis is very necessary; the current detection device usually has the following shortcomings: it can only detect the power of one or several units in the energy transmission process of the electric forklift, for example, some devices can only measure the power of the motor but not the hydraulic power; Simultaneous measurement of all key nodes in the energy transfer process; only physical quantities (voltage, current, pressure, etc.) can be detected and recorded, but the accumulated energy cannot be calculated and the loss analyzed; therefore, no real-time detection and analysis of the energy transfer units of electric forklifts has been found Power Efficiency Instrumentation
