How to reduce unnecessary energy costs in excavator operations

One to reduce unnecessary power loss

1 Accurately apply and protect the exhaust pipe and muffler. It includes frequently removing the carbon deposit in the muffler, repairing the damaged muffler in time, the exhaust pipe is not installed forward, and the self-made too thin and too long exhaust pipe is not applied. Wait.

2 Keep the excavator walking system in good skill state.

3 Strengthen the protection and maintenance of the brake system of the excavator spare parts, especially to prevent the brake from being “stagnated”, that is, the brake friction plate is in contact with the brake drum in the non-braking state. The convenient way to determine the “stagnation” of the brake is to touch by hand. Is the brake drum hot?

4 When the locomotive with the power steering device makes a sharp turn, the steering wheel should be slightly relaxed after the steering wheel is turned to the limit position, so that the spool valve of the distribution valve can return to the neutral position, otherwise the maximum oil pressure in the hydraulic system will be too long, which will lead to the engine. The power consumption is too much, and the wear of the hydraulic excavator parts is increased.

Second, the unnecessary fuel consumption

1. Adding lubricating oil should be suitable. The lubricating oil to the engine oil sump and transmission should not exceed the upper marking line of the oil scale; the filling grease to the wheel wheel can only reach one-half to two-thirds of the space. If the lubricating oil is overfilled, not only the oil is wasted, but also the running resistance of the coherent parts is increased, and the power loss of the engine is increased.

2. Fair application of the throttle according to different working conditions is not only a necessary condition for ensuring the normal operation of the locomotive, but also an important measure for saving energy. For example:

When the excavator engine parts, it should first crank the crankshaft for several times, then start with the middle throttle. If it is started with a large throttle, it can not be started several times, and the fuel is easily "flooded" the engine;

When starting the excavator, the throttle should be properly increased to prevent the engine from stalling. If the engine is restarted, it is very oily;

When the excavator accelerates, it should accelerate slowly and not accelerate. According to the experiment, the vehicle accelerates from the start to the medium speed (30km/h), and the fuel consumption of the rapid acceleration (25s) is about the slow acceleration (40-45s). 2 times the fuel consumption;

In the excavator driving, the economic speed should be adopted, which is safe and fuel-efficient;

When the China excavator parts factory is being repaired and inspected, if the crank is to close the throttle, the injector will continuously inject oil into the cylinder. Excessive fuel will enter the cylinder, which will not only waste fuel, but also cause the next start to be difficult, and some fuels will be smooth. The cylinder wall flows the oil sump, which easily causes the oil to deteriorate, thereby accelerating the wear of the machine and reducing the power of the engine;

When the excavator is parked, if the vehicle stops for more than 10 minutes, the engine should be turned off. It is very harmful to the engine due to long idle operation, and it is wasted fuel. It is forbidden to "boom the throttle" before parking, and the "bumper" before parking is harmful to the engine. https://jnjmzm.wixsite.com/sdjygcjx
