What to do if the small excavator is unable to go uphill?

[BONOVO]

One: Cause of the problem

1. It may be that the travel motor is damaged and the uphill is weak;

2. If the front part of the walk is broken, the excavator will not be able to climb uphill;

3. The small excavator cannot climb uphill, it may also be a problem with the distributor. Repairing an excavator is a technical activity used to restore the function of the equipment after the equipment deteriorates or fails, including various planned repairs and unplanned fault repairs and repairs. It is also called equipment maintenance. The basic content of equipment maintenance includes: equipment maintenance, equipment inspection, and equipment maintenance.

Two: Fault repair

1. First, keep the travel motor and engine, and then the fault still indicates that the fault is not here;

2. Secondly, the front part of the walk, after replacing the pilot valve, the uphill still exists;

3. After removing the distributor for inspection, the internal components are damaged. After replacing the damaged parts, the uphill fault of the excavator was successfully eliminated.

Three: How to clean the small excavator tank and cooling system

The simple way is to clean it, you can prepare a small air compressor. Release the fuel during the cleaning process, but be careful not to let it go and leave some fuel. Then the compressed air reaches the bottom of the fuel tank through the plastic pipe, making the diesel engine roll continuously for cleaning. During this process, the position and direction of the gas pipe are constantly changing, thereby cleaning the entire fuel tank. After the purge, the fuel tank is immediately emptied so that the impurities suspended in the oil flow out with the diesel fuel. If the outflowing diesel is dirty, it needs to be cleaned again by the above method until the released oil is free of impurities.

The steam method works well, but it is only suitable for qualified applications. If you have the conditions to use steam, you can try it. When cleaning, it is necessary to drain the diesel, take out the tank, and then pour a lot of water into the tank, introduce the fuel from the refueling port into the water, and boil the water in the tank, which takes about an hour. At this time, the glue and various impurities adhering to the inner wall of the tank are dissolved on the wall or peeled off from the wall. Rinse the tank thoroughly twice in a row.

Another commonly used method is the solvent method. The chemicals used are corrosive or corrosive. First, clean the tank with hot water, then blow it dry with compressed air, then immerse the 10% aqueous solution in the tank, and finally rinse the inside of the tank with clean water.

After the small excavator engine is turned off, wait for the temperature to drop, drain the coolant, add 15% solution, wait for 8 to 12 hours, start the engine, wait for the temperature to rise to 80-90 degrees, stop the cleaning solution, and immediately release the cleaning solution to prevent scale precipitation. Then rinse with water until it is washed.
Some cylinder heads are made of aluminum alloy. At this time, the cleaning solution can be prepared according to the ratio of 50g sodium silicate (commonly known as soda ash), 20g liquid soap, 10kg water, cooling system and about 1 hour. Washing solution and wash with water.
