Komatsu 360-7 Excavator Generator Belt Broken! What is the reason for high water temperature?

The generator belt is driven by the diesel engine crankshaft, and the load consists of the generator and the cooling fan.

The purpose of the cooling fan is to use forced air to remove heat from the engine radiator tank. Thus reducing the engine crankcase temperature.

When the belt is broken, the generator stops producing electricity and the fan stops rotating, so the cooling function of the water tank disappears. Naturally, there will be a high water temperature alarm soon.

Is it normal for the excavator generator to have a power of up to 32 volts?

Yes. However, the generator must be repaired or replaced as soon as possible, otherwise the battery will not be recharged and the excavator will not be able to start when restarted. Can walk. An excavator, also known as an excavator, is an earthmoving machineoperation that uses a bucket to excavate materials above or below the bearing surface and loads them into transport vehicles or unloads them into the stockyard.

Can the excavator engine still be used after being burned by fire?

This is not normal. According to the request for relevant public information, the battery voltage of the excavator is 24V and the generator voltage is 28V. The generator regulator of the excavator reaches 32V because the regulator is broken, resulting in excessive energy production. to replace it immediately. The generator of an excavator is usually an alternator driven by a diesel engine, also called a generator.

Hello, it depends on the degree of fever. The operating weight is one of the three important parameters of the excavator (engine power, bucket capacity, operating weight).

The operating weight determines the level of the excavator et the upper limit of the excavator's digging force.

Excavation force ≦m; useful weight

m: coefficient of adhesion between the ground and the track

If the digging force exceeds this limit, in the case of a backhoe downwards, the shovel will slip and be pulled forward, which is very dangerous. When shoveling forward, the shovel will slide backward.

Digging force

For the digging force, the digging force is mainly divided into the arm digging force and the bucket digging force.

The point of action of the two digging forces is the root of the bucket tooth (the bucket lip), but the forearm digging force comes from the front cylinder -arm ; The digging force of the bucket comes from the oil cylinder.

Bucket digging force

Specific grounding pressure

Specific pressure at grounding Size determines the conditionsons of the soil in which the shovel is suited to work.

Ground pressure refers to the pressure exerted by the weight of the machine on the ground, expressed by the following formula:

Specific ground pressure = working weight ÷ total surface area in contact with the ground

Track shoes

·It is very important to install suitable track shoes on the machine. For tracked excavators, the selection criterion for tracks is: whenever possible, try to use the narrowest track shoes.

·Commonly used track types: toothed track shoes,

flat track shoes

travel speed

For excavators on tracks, accounts for walking time for approximately one tenth of the total working time.

Generally speaking, two speeds can meet the walking performance of the excavator.capable.

Tensile force

The tensile forcerefers to the force generated by the excavator when walking, which mainly depends on the excavator's moving motor.

These two walking performance parameters indicate the maneuverability and walking ability of the excavator. This may be reflected in samples from different manufacturers.

Climbing ability

Climbing ability refers to the ability to ascend, descend, or stop on a solid, flat slope.

Two expression methods: angle, percentage

Lift capacity

Lift capacity refers to the lesser of the rated stable lifting capacity or rated hydraulic lifting capacity.

Rated stable lifting capacity: 75% of tipping load

Rated hydraulic lifting capacity: 87% of hydraulic lifting capacity

Top speed swing

< p >Swing speed refers to the average maximum speed at which the excavator canachieve stable rotation when unloaded.

This means that the set rotation speed does not refer to the starting or braking rotation speed; that is, it does not refer to the rotational speed of acceleration or deceleration. For general excavation work, when this type of excavator works in the range of 0° to 180°, the swing motor accelerates or decelerates. When it rotates in the range of 270° to 360°, the rotation speed reaches stability.

Therefore, in actual excavation work, the rotation speed defined above is unrealistic. In other words, the actual turning performance required is the acceleration/deceleration expressed by the turning torque.

Engine horsepower

Gross horsepower refers to the flywheel power of the engine without energy-consuming accessories such as mufflers, fans, alternators and filters to haver. The output power measured above.

Effective power (net power) refers to the power output measured at the flywheel when all power-consuming accessories are installed, such as mufflers, fans, alternators and air filters.

Determination of noise

The main source of excavator noise is the engine.

Two types of noise: measuring noise in the operator's ears and measuring noise around the machine.

I hope this helps you.
