One type of diesel generator sets belong captive power AC-powered device, it is a small independent power generation equipment Weifang Huadong BIDDING to the internal combustion engine powered, driven synchronous AC generator and produce electricity. Modern diesel generator set by the diesel engine, three-phase AC brushless synchronous generator, control box (screen), cooling water tank, couplings, fuel tank, muffler and public base and other components of the overall steel. Flywheel generator housing front cover of the diesel engine using the axial positioning shoulder formed integrally directly connected, and the cylindrical rotating flywheel by a flexible coupling direct drive generator, which are secured together by a screw connection mode, so that the two It is connected into a steel body, to ensure the concentricity of the range diesel engine crankshaft and the generator rotor prescribed. In order to reduce the vibration of the unit, in diesel engines, generators, water tanks and electrical control box, and other major components of the common base junction Weifang Huadong units, usually they are equipped with rubber shock absorber or cushion. In order to facilitate production management and use of the national standard GB2819 model designation for diesel generator sets made uniform provisions. Type arrangement and symbols meaning the unit is as follows: 1, the unit output power rating (KW) is represented by a number. 2, the type of unit output current: G- AC power frequency; P an exchange of intermediate frequency; S a dual exchange; Z has been flowing 3, type units: F- land use; FC a ship; Q- car station; T a Hanging (drag) car. 4, the control unit's features: the absence of a manual (ordinary); Z- automation; S- low noise; SZ- low noise automation. 5, the design number, numerical. 6, variant code, expressed numerically. Diesel generator can run a single unit to be incorporated into multiple parallel operation and power system operation. Single-unit operation is limited in many conditions: if its power to meet the heavy-duty working conditions, will reduce light load unit operation economy Weifang Huadong unit sales, and its reserve units but also with the same capacity as the operation of the unit. Using multiple units operating in parallel and connected to the grid running, you can expand the supply capacity, improving supply reliability, its reserve units with a retail unit to Shandong in East China, the relative reduction in the capacity of the spare unit. Achieve parallel operation must meet the following four conditions: ① terminal voltage equal; ② frequency equal; ③ the same phase; ④ phase sequence. But also have run protection devices, can automatically adjust the rational allocation and active and reactive power, the FM feature and regulating characteristic curves between units tends to close. Weifang East China unit sales, Weifang Huadong units, Weifang Huadong by Weifang Huadong Engine Co. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) strong, credible, in Shandong Weifang engine industry has accumulated a large number of loyal customers. The company better work attitude and constantly improve Weifang Huadong innovative ideas will lead into the brilliant and you work for a better future!
