Parameter Configuration of Shangchai Diesel Generator Set

Sep. 28, 2022

Shangchai diesel generator set is powered by diesel engine and was originally produced by Shanghai Diesel Engine Co., Ltd. This type of diesel generator set is the earliest and most widely used diesel generator set in China. In the process of purchasing a diesel generator set, it is very important to master the structural characteristics and rated parameters of the diesel generator set. Today, Starlight Power Equipment will take you to understand the structural characteristics and rated parameter configuration of Shangchai diesel generator sets.

1. Structural characteristics of Shangchai diesel generator set

(1) Integral crankshaft, gantry type body, flat-notch connecting rod, short piston, compact and reasonable appearance, strong matching adaptability, and can be interchanged with the old 135 diesel engine;

(2) A new type of constricted combustion chamber is adopted to increase the fuel injection pressure, improve the combustion process, and achieve environmental protection indicators: the exhaust pollutant emission value meets the requirements of JB8891-1999, and the noise meets the requirements of GB14097-1999 and has a margin;

(3) The optimized design of the lubrication and cooling system reduces the number of external pipelines and parts, and uses the overall brushless alternator to greatly improve the three leakage and greatly enhance the reliability;

(4) J98 and J114b exhaust gas turbochargers are used to match, with strong plateau working ability. When used in plateau areas with an altitude of 5000m, the power drop is less than 3%;

(5) Adopt measures such as high vacuum new exhaust ejection device, three-stage swirling German paper filter element air filter, low temperature infiltrated ceramic piston ring and other measures. Diesel engines are used in deserts or high dust areas, and there will be no early stage. wear;

(6) The 138 series diesel engine is an improved version of the 135 series, and the basic parts are common to the 135. It is produced by the large national enterprise Wuxi Power Plant.

2. Rated parameters of Shangchai diesel generator set


(1) Rated power (pe): Refers to the maximum active power that the diesel generator set can output under rated operating conditions, in kilowatts (kW) or megawatts (MW).

(2) Rated power factor (cosφ): refers to the power factor of the motor during rated operation.

(3) Rated voltage (Ue): refers to the line voltage of the diesel generator set during normal operation, in volts (V) or kilovolts (kv).

(4) Rated current (Ie): refers to the line current of the diesel generator set running in the rated state, in ampere (A) or kiloampere (kA).

(5) Rated rotational speed (nc): The rotational speed required by the diesel generator set to maintain the frequency of the alternating current at 50Hz, the unit is revolutions per minute (r/min).

(6) Rated efficiency (ηe): refers to the efficiency of the diesel generator set when it is running in the rated state.

(7) Rated frequency (fe): my country stipulates that the rated frequency is 50Hz.

(8) Rated temperature rise: the allowable temperature rise of the stator winding and rotor winding of the diesel generator set in operation compared with the ambient temperature. my country stipulates that the ambient temperature is calculated at 40 ℃.
