How to Reduce Noise When Using Excavator?

To effectively deal with the temperature noise of small excavators, one of the most important measures is to clean the radiator frequently. To ensure the normal use and cleaning of the radiator is to ensure that it can dissipate heat during operation. If the temperature of our small excavator rises and we need to lower the temperature, we will check the hot air to see if there is too much dust around the radiator, and clean the radiator in time. In many cases, high temperature phenomena are caused by problems with the radiator. We have to regularly check some debris on the surface of the radiator and a large amount of internal scale and so on.

The rotor shape and fixed relationship are improved to reduce vibration, and the oil pump is directly connected to the crankshaft to reduce vibration and make it more reliable. Reduce bearing knocking and mechanical noise:

  1. Select a bearing assembly.
  2. Optimize gear shape.

Reduce sound transmission:

  1. The baffle structure is arranged in the flywheel chamber.
  2. Apply engineering principles to design fans.
  3. Increase the hardness of the cylinder block and gearbox, adopt the unique CAE technology of the excavator, optimize the strength of the cylinder block, reduce the transmission noise, and reduce the transmission noise.
  4. Perform vibration analysis to optimize design options.

Use skills of excavators in various operations

  1. Excavator operating techniques: First, check the surrounding conditions. Pay attention to the surrounding obstacles and terrain when turning, and operate safely; when working, confirm the front and rear directions of the track to avoid tipping or impact; try not to face the final drive in the direction of excavation, otherwise it is easy to damage the travel motor or hose; when working, ensure that the left and right The track is in full contact with the ground, improving the dynamic stability of the machine.
  2. Effective mining method: When the bucket cylinder and connecting rod, forearm cylinder and stick are at 90 degrees, the digging force is the largest; when the bucket teeth and the ground maintain an angle of 30 degrees, the digging force is the best and the cutting resistance is the smallest; use a stick When digging, the angle of the stick should be between the front 45 degrees and the back 30 degrees. Using the boom and bucket together increases digging efficiency.
  3. Rock excavation: Excavating rocks with a bucket will cause great damage to the machine and should be avoided; when excavating, the position of the bucket body should be adjusted according to the direction of the cracks in the rock to make the bucket dig smoothly; insert the bucket teeth into the cracks of the rock, use the stick Excavate with the digging force of the bucket (pay attention to the slippage of the bucket teeth); before using the bucket to dig, the unbroken rock should be broken first.
