● Fuel pressure requirements: 1. Inlet pressure of LNG genset: 0.4Mpa-0.7Mpa 2. Inlet pressure of CNG gensett: 0.1Mpa-0.7Mpa 3. Biogas genset inlet pressure: 3.5Kpa-10Kpa 4. Inlet pressure of pipeline natural gas genset: 0.1Kpa-10Kpa Note: The above pressure is the main scope of use, please use the appropriate gas pressure for 1 mw gas generator according to the technical agreement signed by both parties. ● Coolant： The engine should adopt softened water as the coolant, and the antifreeze solution should be added when the ambient temperature is lower than 5℃. Relationship between engine coolant ratio and ambient temperature Coolant Ratio Ambient Temperature Ethanol content (volume ratio)% Water content (volume ratio)% ≥5° 0 100 -10°C～5°C 33 67 -26°C～-10°C 50 50 -35°C～-26°C 56 44           Antifreeze capacity of 3 mw gas generator: 330L The cooling liquid should be a long-term antifreeze with anti-rust, anti-scaling and anti-freezing effects. l engine oil： The engine must be added with a gas engine (CNG/LNG) special oil and the oil grade should have determined according to the on-site annual temperature range as specified in the following table.   Comparison of oil grades in different environment temperature Engine Oil Grade Range of temperature variation 15W/40 -20℃～40℃ 10W/40 -25℃～40℃ 5W/40 -25℃以下   Range of temperature variation Refueling time Oil addition amount (L) First fill 38 Oil Change 37 1. Change the oil filter every time you change the oil 2. Do not check the level of lubricating oil when the engine is running 3. Different brands of oil are not allowed to be mixed 4. Oil pressure range during normal operation of the unit: 100～600kpa (oil temperature ≥80℃) 5. The amount of oil should be kept within the correct scale   Installation Requirements： ●Exhaust system requirements: If the engine needs an external exhaust pipe, keep the pipe unobstructed, and try to avoid the pipe being too long or turning abruptly. When the exhaust pipe is connected to the outdoors, the outer pipe mouth should be inclined downward a little so that the condensed water in the pipe can flow out. ● Installation Requirements: The unit of Natural gas generator set should be fixed on the foundation, the longitudinal inclination during operation is less than 10 degrees, and the lateral inclination is less than 5 degrees. ● Circuit system requirements: The quality of the external cables of the gas generator 500kw should conform to the national standards, and the model specifications should be selected according to the capacity of the unit, and implemented in accordance with the national standards to avoid accidents.     Contact: Sichuan Rongteng Automation Equipment Co., Ltd.
