The problem of “burning oil†on sewage suction trucks and suction trucks cannot be ignored. After reading our decomposition, let your car stay away from the hazards of “burner oil†and cherish the car will bid farewell to “burner oilâ€!
The “burner oil†has a great harm to the vehicle. It will not only damage the oxygen sensor of the vehicle too quickly, but also lead to increased carbon deposition in the combustion chamber, unstable idling speed, poor acceleration, increased fuel consumption, excessive exhaust emissions, and other serious consequences. Insufficient engine lubrication causes the engine to cause unrepairable damage and even scrap, resulting in a substantial increase in maintenance costs and even hidden accidents. For the sewage suction trucks and suction truck owners, how do you identify whether there are "burner oils" in the sewage suction trucks and suction trucks?
Phenomenon 1: The main performance of "burner oil" is to emit blue exhaust gas at the tail when driving, which means that too much oil enters the combustion chamber to participate in the combustion.
Phenomenon 2: The oil dipstick detects excessive oil consumption.
Detection method: After the cold car starts in the early morning, check whether the exhaust pipe will emit blue smoke; whether the exhaust pipe emits a lot of blue smoke when the vehicle is driving or when the engine slams on the throttle in place; in addition to the exhaust pipe, the oil port From time to time also take the blue smoke.
Experts say that because the valve oil seal is worn out after a long period of use and is seriously worn out, it has been unable to achieve a good sealing effect. Therefore, some vehicles with a long service life or a large number of driving kilometers are more prone to “burning oil†phenomenon. The reason for choosing to test in the early morning cold car is that when the engine is not running for a long time, the oil will flow into the cylinder through the gap of the valve oil seal under the action of gravity. As soon as the engine is started, the oil in the cylinder will be burned under the effect of high temperature and high pressure, producing a large amount of blue smoke. The method of slamming the throttle is mainly to check whether there is loose seal between the engine piston ring and the cylinder wall. When the vehicle accelerates rapidly, the frequency of up and down movement of the piston ring is accelerated, and residual oil on the cylinder wall is easily brought into the combustion chamber by the piston ring, resulting in “burning oilâ€. If, under any circumstances, the exhaust pipe emits blue smoke and the engine oil port emits blue smoke from time to time, it indicates that the wear of the engine has become quite serious and the vehicle needs to be overhauled in time. Otherwise, serious accidents may occur.
Engine oil is crucial to the protection of the engine. There are many causes of “burning oil†phenomenon. Engine oil is volatile, engine running-in, engine type, etc. may cause the engine to “burn oilâ€, but by strengthening the daily maintenance of the car, This risk can be mitigated and avoided. So, what maintenance tips should be taken care of?
1, develop a good inspection habits. The oil should be regularly inspected according to the different conditions of use during regular routine and daily maintenance. If the oil level exceeds the lower limit, it should be added in time. For vehicles that have a longer service life and mileage and are often used in harsh conditions, the frequency of inspections should be increased accordingly. In this way, even if the vehicle appears to "burn oil", it can achieve "early detection and early treatment" and reduce maintenance costs.
2, choose better quality gasoline. After the additives in gasoline are oxidized, a gelatinous substance is formed. After the fuel is injected into the combustion chamber, carbon deposits are formed in the intake valve, piston top, piston ring groove, combustion chamber, spark plug, etc., which intensify these parts. The aging causes "burner oil." Therefore, the use of better quality gasoline can reduce the phenomenon of “burning oilâ€.
3, regular maintenance of vehicles. The maintenance cycle of the vehicle is based on the normal driving conditions of the vehicle. The vehicle with a relatively poor use condition must be shortened according to the actual situation and the prescribed number of kilometers should be reduced.
Air preheater is one of the most important accessories in modern boilers. Air preheater is commonly found in all modern boilers. To increase the efficiency of the boiler accessories like air preheater is used in the boilers.
Types of air preheater in a boiler
The air preheaters are classified into two types based on their features and construction. These two types of air preheater are
Recuperative or Tubular type air preheater
Regenerative or Rotational type air preheater
Recuperative or Tubular type air preheater is further classified into two types, they are
Horizontal tubular type
Vertical tubular type
Regenerative or Rotational type air preheater is also classified into two types they are
Rotating baskets (Ljungstrom)
Rotating hood (Rothemuhle)
