Why is the crane noisy after a long time
After using the crane for a period of time, a certain amount of noise will be formed. Natural noise is difficult to avoid, but we can do some optimizations to reduce the noise.
What is the cause of noise caused by cranes?
1. Under normal conditions, there is gas injected into the hydraulic oil of single and double girder bridge cranes, which may cause the working pressure of the hydraulic oil to be unbalanced; gradually, the gas generates bubbles inside. When the bubble follows the fluidity of the hydraulic oil to reach the high pressure area, the volume of the bubble may be squeezed. At this time, the volume of the bubble may generate noise.2. When the bridge crane is running, the mutual repulsion of components will also cause noise. In this type of situation, the noise generated is attributable to the hazard of the relative density of the product workpiece.
3. The internal function of the speed control valve of the bridge crane is unstable, which will also cause the vibration of the machinery and equipment, and then the noise.
So how to deal with the noise of the crane?
For the reason of the noise caused by the above, we can analyze the construction method of the double beam crane in detail, and increase the raw materials in the areas prone to radiation source noise. The construction of some very simple thick steel plates, such as the hoisting equipment aisle, also requires strict production and installation methods in accordance with technical regulations to prevent the occurrence of radiation source noise like large and medium-sized parts. The ribs can be used to dampen vibrations, and sound insulation materials can be embedded in important parts of the lifting equipment.A unique connector can also be used to prevent structural noise from being transmitted from one part to another. As everyone knows, the key way is to reduce noise from the root source as soon as possible, that is, to select quieter components. If the high-quality three-in-one motor is used to drive, the transmission system components are reduced; the lifting equipment adopts the frequency converter to adjust the system software, so that the impact of lifting and operation is reduced to a lower level.
The noise of the crane is impossible to subside by itself. But we will work diligently to reduce the noise level and make our office environment more and more comfortable.
