(1) diesel generator room, taking into account the location of the air intake of diesel generator set, exhaust, smoke, etc., if the conditions best room in the first floor. However, expensive high-rise buildings, especially the first floor is typically used for business, is a gold zone, so 800kw generator rental, room generally located in the basement. Due to the basement and out inappropriate, natural ventilation adverse conditions brought a series of negative factors to room design, the design should pay attention to deal with. Siting room should note the following: ① should not be located around the room without exterior walls, creating conditions for hot air pipes and exhaust pipes exporting outdoor; ② try to avoid the main entrance of the building, the facade and other parts, avoid smoke, exhaust its impact; ③ Note the noise impact on the environment; ④ should be close to the substation generator rental of buildings, it is easy to wiring, reduce energy consumption, but also facilitate the operation and management. (2) diesel generator room ventilation ventilation problem is room design should pay special attention to problems, particularly when located in the basement room more properly handle, otherwise it will directly affect the operation of diesel generator sets. Exhaust hot air units should generally be set up pipeline, should not let the heat sink diesel scattered in the room, and then out of the exhaust fan. The engine room have enough fresh air supplement. Diesel engine is running, the engine room ventilation should be equal to or greater than the fresh air required for combustion of diesel and maintain the desired room temperature and fresh air. Diesel generators which are generally important technical indicators Zhangzhen Yi:? User value is diesel generator set can instantly start when needed, and to reveal the excellent load power. For this reason an important technical indicators are concerned; when one diesel generator set with a heavy load or with load changes, its output voltage will therefore change into a new value, this change is defined as the voltage stabilization time period Su. It is the smaller the ability to respond to load changes, the stronger the unit, Su is generally from 0.5 to 3 seconds. Then change into the new value of the output voltage at no load and the setting value (380V or 400V) by dividing the difference between the output voltage setpoint as a percentage of the steady-state voltage regulation δu, which represents the change in output voltage unit for load variations caused adjustment function. δu usually between ± 3 ~ ± 5%. Or when the load changes with 120kw generator rental, Su and δu are zero is the ideal state, diesel generator sets minimum seek their values. Second is a diesel generator set under the above conditions, its output voltage and frequency changes with the load condition. Defines the frequency settling time and steady-state frequency regulation St δf two parameters. They are also the smaller the better 1500kw generator rental, instructions and regulatory capacity of the unit to respond to load changes caused due to the frequency change. St range 2 to 7 seconds, δf between 0.5 and 5%. Third, the effective rate of the diesel engine fuel consumption ge and effective efficiency ηe. The former is defined as the amount of fuel within one hour per kilowatt output effective power, consumed by the internal combustion engine. This is a measure of the fuel consumption of a diesel engine important indicator, ge usually between 220 to 285 grams. The latter is defined as the transformation of one kwh effective heat and power to complete one kwh than the effective work of the heat consumption. value ηe is generally 0.7 to 0.85. It shows the effective efficiency of the diesel engine, the larger the better. 250kw generator rental _ diesel generator (certified) _ generator rental is provided by Shenzhen, Dongguan and Electrical Equipment Co.
