15kva-500kva Open/Silent Nature Gas Generator Sets
The natural gas generator unit is an ignition gas machine fueled by gas of high calorific value such as natural gas.On the basis of the non-supercharged model, the supercharging system and the intermediate cooling system are added. The cooling system adopts the method of separating the high and low temperature cycles. The high temperature cycle cools the cylinder, the body, the cylinder head and other high temperature components, and the low temperature cycle cools the gas, air and oil coolers after the supercharging.
Gas, oil and coolant:
Before the use of a natural gas generator engine, appropriate specifications of natural gas, oil and coolant should be selected according to the specific environment and conditions of use.The proper selection or not has great influence on the performance and service life of the engine of the natural gas generator set.
1.Requirements for the use of gas in natural gas generating sets:
The fuel of gas engine is mainly natural gas, but it can also use inflammable gas such as oil field associated gas, liquefied petroleum gas and methane gas. The gas used shall be desiccated to be free of free water, crude oil and light oil, with a low calorific value of not less than 31.4 mJ /m3, a total sulfur content of not more than 480mg/m3, and a hydrogen sulfide content of not more than 20mg/m3.In addition, the natural gas transport pressure is within the MAP range of 0.08-0.30.
2.Oil used in a natural gas generator set：
Oil is used to lubricate the moving parts of a natural gas engine and to cool and dissipate heat, remove impurities and prevent rust from these moving parts. Its quality not only affects the performance and service life of the gas engine, but also affects the service life of the oil.Therefore, the appropriate oil should be selected according to the operating environment temperature of the gas engine of the natural gas generator.For natural gas engines, 15W40CD or 15W40CC, etc. are used as far as possible
3.Natural gas generators use coolant:
The coolant used for direct cooling of engines for cooling systems usually USES clean fresh water, rain water or clarified river water.When the natural gas engine is used under the environment condition of less than 0 degree, it should be strictly prevent the coolant to freeze, which will cause the parts to freeze crack.Can be used according to the temperature of the appropriate freezing point of antifreeze or in the start before filling hot water, but should immediately after the stop water.
