How much is the price of on-site dynamic balancing instruments with different functions?
How much does the dynamic balancing instrument cost? The price of on-site dynamic balancing instruments varies from high to low, simple to complex, with or without analysis software. The choice is mainly based on the user's purpose and actual situation. If only single-sided balancing and price reduction are needed, choose a lower price. If analysis and judgment of problems are needed, choose to use computer analysis. You get what you pay for, ranging from a few thousand yuan to 50000 to 60000 yuan, and whether training is needed should also be considered.
Firstly, we will understand the concept and necessity of on-site balancing. Commonly used machinery contains a large number of rotating components, such as various transmission shafts, main shafts, rotors of electric motors and steam turbines, collectively referred to as rotors. In an ideal situation, the pressure exerted on the bearings is the same when the rotating body rotates and when it does not rotate, making it a balanced rotating body. However, various rotating bodies in engineering, due to uneven material or blank defects, errors in processing and assembly, and even asymmetric geometric shapes during design, cannot cancel each other out when rotating. The centrifugal inertia force generated by each small particle on the rotating body cannot be balanced. The centrifugal inertia force acts on the machinery and its foundation through bearings, causing vibration, noise, accelerating bearing wear, shortening mechanical life, and in severe cases, can be destructive. For this reason, it is necessary to perform dynamic balance correction on the rotor to achieve the allowable balance accuracy level, or to reduce the amplitude of the resulting mechanical vibration within the allowable range.
A portable on-site dynamic balancing instrument is a measuring device that is more convenient to carry than ordinary horizontal and vertical balancing machines. Its volume is greatly reduced, and it does not rely on external power transmission. As long as the equipment is in operation, its dynamic balancing data can be determined. It is possible to quickly assess the operation status of the equipment on site. After using the system influence coefficient to determine the standard, the system will automatically calculate the size and angle of the added (subtracted) weight, and eliminate the imbalance on the equipment or shaft through dynamic balancing. Just need the speed signal and the vibration signals at both ends connected, the connection is simple and not limited by any space. According to the 602 computer measurement system, the instrument can measure single-sided balance and double-sided balance. Rotating objects such as fans, motors, impellers, and main shafts are all measured by on-site balancing instruments.
The difference between rotor dynamic balance and static balance:
Static balance: Calibration balance is carried out on one calibration surface of the rotor, and the remaining unbalance after calibration is ensured to ensure that the rotor is within the specified range of allowable unbalance during static state, which is called static balance or single-sided balance. A news story caused a sensation in the chemical industry, and in addition, it will make it easier for near-infrared spectroscopy to be better applied in new fields.
Dynamic balance: Simultaneously correcting the balance on both calibration surfaces of the rotor, the remaining unbalance after correction, to ensure that the rotor is within the specified range of allowable unbalance during dynamic operation, also known as double-sided balance.
