What Are The Consequences Of Improper Operation Of The Biogas Generator?

Weifang Yidaneng Power Co.,Ltd | Updated: Oct 26, 2017

What are the consequences of improper operation of the Biogas Generator?
1, after the cold start is not warm up with load operation:
Biogas Generator cold start, due to oil viscosity, poor mobility, oil pump oil is lacking, the friction surface of the machine due to lack of oil smooth bad, the formation of sharp wear and tear, as well as the development of cylinder, burning tile and other problems. Therefore, the Biogas Generator Biogas Generator after the start of the cooling should be idle operation temperature, the oil temperature reaches 40 ℃ or more when the load operation; machine starting should be linked to low speed, and in a row in each gear driving mileage, until the oil temperature Normal, abundant oil, can be transferred to normal driving.
2, with a load emergency stop or suddenly unload the load immediately after the shutdown:
The Biogas Generator is turned off after the cooling of the water cycle, the cooling can be drastically reduced, the heat loss of the cooling, easy to form cylinder head, cylinder liner, cylinder block and other parts overheating, resulting in cracks, or excessive piston stuck in the cylinder Inside. On the other hand, the Biogas Generator shutdown without idling cooling, will make the friction surface lack of oil, when the Biogas Generator will start again due to smooth bad and exacerbate wear. Therefore, the Biogas Generator should be unloaded before the load, and gradually reduce the speed, no-load operation for a few minutes.
3, in the absence of cooling water or cooling water, oil temperature is too high to run the situation:
The lack of cooling water in the Biogas Generator will reduce its cooling effect, and the Biogas Generator will overheat due to lack of effective cooling. The oil temperature of the cooling water and oil will also cause the Biogas Generator to overheat. At this point the cylinder head, cylinder liner, piston components and valves and other major heat load, its mechanical properties such as strength, toughness and other sharp landing, so that parts deformation increases, reducing the gap between the parts to accelerate the wear and tear, serious But also produce cracks, mechanical parts of the problems. Biogas Generator cooling water, oil temperature is too high will speed up the oil aging transformation and burning, and the oil viscosity drop, casing and piston and the main friction conditions of the conditions of deterioration of the smooth conditions, resulting in abnormal wear and tear. Biogas Generator overheating will also deteriorate the Biogas Generator extinguishing process, so that the injector work disorders, poor atomization, coke increased.
After the long-term operation of the Biogas Generator, a fault has occurred and the following phenomena are usually encountered.
(1) abnormal sound when the operation of the Biogas Generator is running abnormal percussion, firing sound, booing, exhaust sound, periodic friction sound and so on.
(2) abnormal operation Biogas Generator is not easy to start, work violent vibration, drag the load, speed instability and so on.
(3) the appearance of abnormal Biogas Generator exhaust pipe to take white smoke, black smoke, blue smoke, the system leakage, leakage, leakage and so on.
(4) temperature abnormal oil temperature or cooling water temperature is too high, such as bearing overheating.
(5) odor abnormal Biogas Generator operation, the smell, smell, smoke and other smell.
Biogas Generator running into the above abnormal phenomenon, must be carefully investigated, according to the phenomenon of failure, analysis and judgment to identify the location and causes of failure. Sometimes a fault may have several anomalies, such as high-pressure pump wear, both performance difficulties can also show that the output power is insufficient, but also the performance of low-speed operation instability and so on. Sometimes an anomaly may have several failures. Therefore, the Biogas Generator running abnormal phenomenon, we must carefully identify the causes of abnormal phenomena, which requires us to make good use of analytical reasoning, through the phenomenon of grasping the essence, to identify the cause and location of the failure, the troubleshooting.
