How to Troubleshoot Diesel Engine Runaway

The diesel engine coaster refers to the sudden loss of control of the speed of the diesel engine during operation, and it is increasingly high. The body vibrates violently, accompanied by an abnormal roar, and the exhaust pipe emits a large amount of smoke. If the diesel engine coaster fails to stop in time, as the speed of the diesel engine increases, the leakage loss between the injection pump plunger and the plunger sleeve decreases, and the diesel fuel that enters the cylinder increases, causing the diesel engine speed to increase further, thereby forming a vicious circle. As the temperature in the cylinder continues to increase, the expansion of the piston increases, and the movement of parts of the piston connecting rod group intensifies. Exceeding its strength limit, it will not only cause major accidents such as breaking the cylinder block, connecting rod breakage, and crankshaft fracture, but also may endanger The personal safety of the pilot. Therefore, when a diesel engine coaster occurs, the farmer must be calm and calm, stop in the shortest possible time, carefully observe the smoke color of the exhaust pipe, determine the cause of the failure, and then take measures to deal with it:

First, the exhaust pipe black smoke. For overspeed caused by diesel oversupply, it can generally be stopped by cutting off the oil supply.

Second, the exhaust pipe to take blue smoke. As the oil enters the combustion chamber and participates in the combustion-induced coaster, the air supply and rapid decompression must be cut off at the same time when the oil supply is cut off.

Specific measures include:

1. Cut off the diesel oil circuit. Quickly release the high pressure tubing or the low pressure tubing connector nut of the fuel injection pump after the speed control handle (pedal) is placed in the non-supply position. Can also be used to break the oil pipeline emergency measures.

2. Rapid pressure reduction. Place the decompression handle of the decompression device in a decompression position.

3. Severely cut off the air. The intake valve is quickly closed. The valveless cover removes the air cleaner cover and blocks the air intake with clothes or Other items.

4. In the operating state, the diesel engine has a racing phenomenon. The brake can be stepped on while the high gear is being loaded to increase the load, and the engine speed can be reduced to extinguish the engine. Do not press the clutch pedal at this time.

5XZ-AB series Gravity Separator (Air suction type)

 

This machine is better for processing the seeds which have been primary selected. It`s based on the theory of granular and density segregation appearance in fluidization, and the different dimensions of the grain. It can select many kinds of seeds, such as wheat, maize, rice, barley and vegetable seeds etc, it also can use for selecting the commodity grain, removing the blighted seed, budding seed, damaged seed (by insect), rotten seed, deteriorated seed, moldy seed, non-viable seed, smut seed and seed with shell, and the light impurity, large heavy impurity and the small impurity which dimension is less than 2 mm. The germination rate, regularity , thousand-seed weight and neatness etc will improve .

This machine also can be used for primary selecting. It's forbidden to feed in straw, foliage , stick and other big impurity, in order to avoid blockage. It will reduce the neatness after selected as material is too dirty.

This machine is suitable for kinds of seed company and agricultural products processing department.

This machine has many advantages, such as reasonable design, high performance, high capacity, easy operation, convenient migration and reliable running, also the aluminum-alloy vibratory body has many advantages as well, such as light weight, steady movement and long working life.

This machine is available for connecting with other Seed Processing Machine, and become a seed processing unit.
