Diesel generator with variable spring support and vibration reducing control method of diesel generator

Abstract

The invention aims at providing a diesel generator with a variable spring support and a vibration reducing control method of the diesel generator. The support can be automatically regulated along with the working condition of the diesel generator, and therefore the vibration reducing effect of the diesel generator is improved. The diesel generator comprises the support and a diesel generator body; the support is composed of a bottom plate, a support plate, a framework, springs, an air pump and an air bag, the bottom end of the framework is closed, and the top end of the framework is open; the bottom plate is movably installed on the lower portion of the framework, the support plate is supported over the bottom plate through the springs, and the diesel generator body is fixedly connected with the upper portion of the framework and located on the support plate; the air bag and the air pump are arranged under the bottom plate, and the top end of the air bag abuts against the bottom plate; the air pump is connected with the air bag to inflate or deflate the air bag; the air pump is provided with a control unit, the framework is provided with a height sensor used for detecting the height of the bottom plate, the diesel generator body is provided with a revolving speed sensor used for detecting the revolving speed of a crank shaft, and the control unit is connected with the height sensor and the revolving speed sensor.

Description

technical field [0001] The invention belongs to the technical field of diesel generators, and in particular relates to a diesel generator with a variable spring bracket and a vibration reduction control method thereof. Background technique [0002] Diesel generator is a small power generation equipment, which refers to a power machine that uses diesel oil as fuel and uses diesel engine as prime mover to drive the generator to generate electricity. and other components for vibration reduction. When the diesel generator is working, it will generate large vibration and noise, which will seriously affect the comfort of the working environment. [0003] In order to deal with the vibration of diesel generators and the accompanying noise, the utility model patent with the patent number of 201420356530.5 proposes a vibration damping seat that can simultaneously and effectively overcome vertical and lateral vibrations and a generator applied thereto. The vibration damping seat comp...

Problems solved by technology

Although the above-mentioned vibration damping seat can reduce vibration at a certain frequency and eliminate certain noise, the most important thing is that the scope of application of the elastic damping body with its fixed structure is fixed, and the vibration frequency of the diesel generator and its crankshaft rotation speed Relevant, it is a very large frequency range, the vibration damping seat of the above patent is difficult to adapt to the vibration reduction of a wide frequency range
