Special environment using emergency generators, should pay attention to:
A. When performing mountain power generation tasks without lead-off line, pay attention: 1) Before going uphill, observe the oil level and the maximum slope of the mountain road. If the fuel leakage cannot be guaranteed, place the generator near the rear of the vehicle; raise the generator; After placing it, check if there is any fuel leak and wipe it if there is any leak. 2) The generator should be placed away from the steep slope. If the ground is not horizontal, it should be solid and flat. It must be ensured that the generator is horizontal and stable.
B. When carrying out the mountain power generation task, if there is a downhole or self-provided cable that can meet the requirements of the downhill power generation, the generator should be placed at a horizontal position that can be directly seen from the base station; and the “climbing operation specification†and “connection climbing line†should be implemented. Power Operating Specifications.
C. When rain and snow are used to perform power generation tasks, pay attention to: 1) Do not place them in low-lying areas, at gutters (including naturally formed small gutters), in difficult-to-drain areas, in soft soils, and not too close to easy collapse. (The distance should be greater than 2/3 of the height of the easily collapsed item). 2) The generator should be protected against rain and snow, but it must not be covered directly. 3) Wear insulating rubber shoes and insulating gloves to avoid damage to the cable.
Valves is one of the key components that affect engine reliability and safety. It's mainly used to start and shut down the intake and exhaust passages during engine operation, to control the intake of fuel mixture or air and the discharge of exhaust gases. . The working environment of the valve and Valve Seat is very harsh. In addition to the corrosion of high temperature gas, it also bears the impact of the burst pressure in the cylinder.
The material of the valve is usually divided into 40Cr, 4Cr9Si2, 4Cr10Si2Mo, 21-4N and 23-8N in China. 5Cr8Si2, 4Cr9Si3, 21-2N, 21-12N, 23-8N, XB, etc. have been used in large quantities on some imported models. High-temperature nickel-based alloys are also being used on high-load diesel exhaust valves.
