At present, a dynamometer is usually selected as loading equipment for internationally controlling the torque and the speed of the rotary machine, and the dynamometer industry in China has low manufacturing technology level and unstable performance and is in a product simulation stage. And power and loading need to consume energy, and especially for tests with large loads and long test time, the cost generated by energy consumption becomes a heavy burden for enterprises.
The dynamometer is generally classified into a hydraulic dynamometer, a vortex dynamometer and an electric dynamometer.
The hydraulic dynamometer has dynamic characteristics of low speed, low torque, high speed and high torque, is not suitable for test loading of a low-speed and high-torque rotating machine, and has the defect of poor unstable vibration loading performance when the rotating speed is lower than a certain value. And the hydraulic dynamometer cannot be used as a back-dragging device and cannot be loaded in two directions. In addition, the hydraulic dynamometer consumes energy during water cooling and energy conversion, and the energy cannot be recovered, so that the energy consumption is large.
The low-speed loading performance of the eddy current dynamometer is inferior to that of a hydraulic dynamometer, the eddy current dynamometer cannot be used as a back-dragging device and cannot be loaded in two directions, energy is consumed during water cooling and energy conversion, the energy cannot be recovered, and the energy consumption is large.
The existing electric dynamometer is a combination of a motor and a generator, the motor is used when the electric dynamometer is started, and the consumed electric energy drives the engine (rotating machinery) to start to run; after the engine (rotating machine) runs, the engine (rotating machine) is converted into a generator, the mechanical energy of the engine (rotating machine) can be converted into electric energy, and the electric energy can be fed into a power grid for utilization. The loading of the electric dynamometer has the advantages of energy conservation, good bidirectional loading and dragging characteristics in a low and high speed range, quick response characteristic of transient loading, anti-dragging characteristic, low capital cost and the like.
Most dynamometer machines at present often appear motor model discordance when using, lead to putting unstablely, cause equipment damage, and the connection between each small subassembly of dynamometer machine is stable inadequately, easily leads to the testing result inaccurate, does not set up the dust cover in the electric dynamometer machine moreover, causes the incident even, for this reason, we provide a take protector's electric dynamometer machine.
