Detailed Description
See fig. 1. A mechanical loop for avoiding leakage of high Wen Duichai fuel oil comprises a cylinder, a dipstick, a daily fuel tank, a return oil pump and an oil inlet pump; one path of the plurality of cylinders is connected with the corresponding dipstick, and the other path of the plurality of cylinders is connected with the fuel leakage pipe; one path of output of the dipstick is connected with the fuel oil double-wall pipe, and the other path of output of the dipstick is connected with the fuel oil inlet pipe; the daily oil tank is connected with an oil inlet pipe through an oil inlet pump; the oil return pipe is connected with the daily oil tank through an oil return pump; the fuel double-wall pipe and the fuel leakage pipe are connected with the input end of the valve; the method is characterized in that: and the output end of the valve is connected with the input port of the oil return pump.
The mechanical loop for avoiding the leakage of the high Wen Duichai fuel oil works as follows:
when the diesel generator normally operates, fuel oil enters the dipstick through the daily oil tank, the oil inlet pump and the oil inlet pipe, and the control system controls the dipstick through parameters such as load quantity, rotating speed and the like so as to adjust the oil quantity entering the cylinder. In the daily operation process, a small amount of fuel oil leaks from two ends of the dipstick and is collected in the fuel oil double-wall pipe; the fuel output by the dipstick also has partial fuel leakage and is collected in the fuel leakage pipe. The two leaked fuel flows into the oil drain container through the manual valve, so that unnecessary waste of the fuel is caused. The manual valve is newly added to the pipeline at the inlet of the oil return pump by removing the pipeline from the manual valve to the oil drain container, and a check valve is added in the pipeline for preventing backflow. After transformation, the fuel oil leakage is collected and is pumped back to the daily oil tank again for continuous recycling.
The mechanical loop for avoiding leakage of high Wen Duichai fuel oil is applied to a diesel generator fuel system, and the diesel generator is started and stopped for many times on site, so that the problem of fuel oil leakage is solved, and the operation requirement of the diesel generator is met.
