Proper intake and exhaust system in diesel generator maintenance room. Indicates that when clean ventilation is used in the diesel generator maintenance room, the intake and exhaust air volume should be calculated according to the following provisions:
1. When the diesel generator is air-cooled, the intake and exhaust volume should be calculated according to the waste heat of the diesel generator;
2. When the diesel generator room is cooled by water, the ventilation volume required by the harmful gas in the diesel generator room should be calculated and determined. The permissible levels of hazardous gases are 30 mg/m3 and 0.3 mg/m3 of carbon monoxide, or 20 m3 /(kilowatt-hour) or more.
Diesel generator sets have been used in airports, hotels, communications and other industries since they came into the market. Facing the steady growth of the industry market, Starlight believes that diesel generator set manufacturers should seize the opportunity to understand the reasons for the steady growth of the diesel generator set industry, in order to better realize the sustainable development of enterprises. The main reasons for the steady growth of the diesel generator analysis industry are as follows: First, new infrastructure construction has increased the demand for mobile power and self-contained power.
According to the national standard (GB252-87), the specification of light diesel is divided into 6 grades according to the freezing point, namely 10, 0, -10, -20, -35 and -50, which respectively means that the freezing point is not higher than 10, 0, -10, -20, -35 and -50. The higher the brand, the lower the freezing point of diesel, a special fuel used in compression combustion engines. The appearance of diesel is water white, light yellow or brown liquid. Diesel is divided into light diesel and heavy diesel. Light diesel is used for high speed diesel engines above 1000 RPM, while heavy diesel is used for low speed diesel engines below 1000 RPM. The diesel sold at ordinary gas stations is light diesel. At PRESENT, the LIGHT DIESEL product standard is GB252-200 “Light DIESEL”, in which the diesel grade is divided into No. 10, No. 5, No. 0, No. 10, No. 20, No. 35 and No. 50, the diesel grade is classified according to the freezing point of diesel.
Diesel generator set according to the purpose of classification, can be divided into three categories: one is the main generator set; Secondary: standby generator set; Level 3: emergency generating set; The following is a detailed description of the selection and configuration of the three types of generator sets:
1. Configuration and selection of the main generator set: the main generator set means that the power of the generator set is the main power. For example, if a 200 kW generator set is the main type, the power output of the set is 200 kW. There are also requirements for the configuration of the main generator set. Generally, a diesel engine of at least 210 kW should be equipped with a motor of 200 kW.
2. Storage location of fuel tanks to prevent fire. The fuel tank or oil drum should be placed in a conspicuous place, appropriate away from Cummins generator set, no smoking;
3. If the fuel tank is manufactured by the user, it should be noted that the fuel tank of the standby generator set is made of stainless steel or steel plate. Do not paint or galvanize the tank interior, as they will chemically react with the diesel and produce impurities that may damage the Cummins generator set and reduce the quality, cleanliness and combustion efficiency of the diesel.
Jiangsu Meao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
