An Analysis of the Causes of Black Smoke in the Sanitation Garbage Engine
Analysis of Causes of Garbage Engine Black Smoke:
Under normal circumstances, when the garbage truck engine is working, the fumes emitted from the exhaust pipe should be colorless and transparent gases. However, sometimes Hu appears to have black smoke in the exhaust pipe; usually this condition is due to the frequent changes in working conditions and environmental conditions with the vehicle conditions, resulting in changes in smoke color, so the engine will fail smoke color will follow change.
Exhaust pipe black smoke, indicating that the mixture is too concentrated and incomplete combustion.
Usually the following conditions will cause this to happen:
1, too late for oil;
2, excessive oil supply or poor atomization of fuel injection;
3, the engine is overloaded.
4, air filter or intake line blocked;
5, cylinder pressure is insufficient;
6, too late to supply oil;
6, excessive fuel supply or poor atomization of fuel injection;
7. The engine is overloaded.
If black smoke occurs, you need to do the following to eliminate the above conditions:
1. Check whether the choke valve is fully opened, and if necessary, perform high-speed maintenance;
2, after the flameout from the carburetor mouth to see the main nozzle, if there is oil injection or drip, then the oil in the float chamber is too high, should be adjusted to the prescribed range, tighten or replace the main amount of hole;
3, check the air filter is blocked, the air filter should be often cleaned, dredged or replaced.
Of course, the engine black smoke, in addition to the above factors, there are other factors, such as supercharger oil return pipe poor, brake system failure sensor failure and other factors, can also cause the engine black smoke phenomenon. In addition, Xiao Bian recommended the majority of owners, we must choose a quality, quality guaranteed oil, to ensure the safety of the car.
CNC milling machining is a CNC machine tool trajectory by means of computer controlled machine, using high speed rotating cutting tool if you want to shape the material. With the size of products have become increasingly demanding, machining from the original two gradually changed to 3 axis machining, 4 axis machining, 5 axis machining center, precision can reach 0.001mm. us the maximum machine processing size: 500mm * 1000mm *600mm, 800kg machine under the maximum weight of workpiece, Machine tool spindle speed 20000RPM to ensure that the surface of the workpiece is smooth and clean.we often processed material of aluminum,steel, copper, stainless steel, titanium, POM, Teflon and so on. At the completion of high quality, high dimensional accuracy of CNC milling machining parts process, we will divided into rough machining and processing method fine to get the best effect, the margin size coarse and finish machining is 0.5 * 1mm. after processing some of the products after surface treatment such as plating polishing surface passivation.Sand (powder), anodic treatment (aluminum common CNC anodized black red blue anode, anode, anode). CNC milling machining is widely used in aviation, automotive, communications, medical equipment, electrical appliances, drone.
In addition to,we also provide high precision machining and precision machined parts,supply custom machining services and cnc machining services for small batch.
