Problems solved by technology

In the production process, the motor needs to be started and stopped frequently. The quality of its starting performance has a great impact on production and consumes a lot of energy. This is because the strong starting current of a high-power motor will cause a large line voltage drop. The reduction of the grid voltage not only affects the normal operation of other electrical equipment, but also has a large impact on the power transformer, and there is a huge rotational kinetic energy when the motor stops rotating, and this part of the inertial kinetic energy is often ignored. , Therefore, in today's society that advocates energy saving and emission reduction, an energy storage device that can store this part of energy and reduce the energy consumption for starting is urgently important
[0003] In order to reduce the start-up current, soft start and step-down start are widely used at present, but this kind of start-up usually has strict working condition restrictions, the start-up energy consumption and start-up time are significantly increased, and the structure is complex

Abstract

The invention relates to an energy-saving device for energy-storing auxiliary starting rotary machinery. A working revolving shaft on the rotary machinery is connected with a driving disk through a single-direction bearing; an electric push rod is connected below the driving disk; the electric push rod is connected with the driving disk in a location fit way; the front end of the working revolving shaft is fixedly connected with a right friction device; the right friction device is connected with a left friction device fixed at the right end of an operating shaft in a matching way; a scroll spring is arranged on the operating shaft; the central end of the scroll spring is fixed on the operating shaft; the outer end of the scroll spring is fixedly connected with the driving disk; the left end of the operating shaft is arranged on a bracket through the single-direction bearing; the bracket is fixedly connected to a slide block of a slider; the bracket is provided with an inner threaded hole, and is in transmission connection with a lead screw through the inner threaded hole; and the lead screw is connected with a servo motor. According to the energy-saving device, collected energy is used for pre-starting equipment, so that starting current is reduced, starting energy consumption is lowered, the equipment starting working condition is optimized, the service life of the equipment is prolonged, and the interference of motor during starting on a power grid is weakened.

Description

technical field [0001] The invention relates to an energy-storage energy-saving device for auxiliary starting of rotating machinery, in particular to an energy-saving device for assisting the starting of high-power rotating machinery or rotating machinery that often works intermittently. Background technique [0002] As the field of science and technology is becoming more and more mature and developed, the application of high-power rotating machinery equipment is very extensive. In the production process, the motor needs to be started and stopped frequently. The quality of its starting performance has a great impact on production and consumes a lot of energy. This is because the strong starting current of a high-power motor will cause a large line voltage drop. The reduction of the grid voltage not only affects the normal operation of other electrical equipment, but also has a large impact on the power transformer, and there is a huge rotational kinetic energy when the motor...
