Measurement of relative rotor vibration using non-contact linear displacement sensors.

With the Balanset-1A you can measure the relative vibration of the rotor using non-contact linear encoders. 1.1 Selection of the sensor type and setting. Depending on the task, either vibration sensors or displacement sensors can be used for measurements. To select the type of sensor it is necessary on the panel “Sensor type” (at the bottom of the main window) to put a mark in the field “Vibro” or “Linear”. Before starting the measurement it is necessary to make sure that the conversion coefficients of the sensors are set correctly. For this purpose press the button “F4-Settings” in the main Read more…

Application of the Fourier transform to the analysis of vibration signals.

Andrei Shelkovenko. One of the developers and founder of Vibromera. The translation of the article may contain inaccuracies. Fourier transform and signal spectrum In many cases the task of obtaining (calculating) the spectrum of a signal is as follows. There is an ADC, which with sampling frequency Fd transforms continuous signal, which comes to its input during time T, into digital samples – N pieces. Then this array of samples is fed to some program (for example FourierScope) which outputs N/2 some numeric values. To check if the program works correctly, we form an array of samples as a sum Read more…

Balancing a crusher rotor can be done using a portable balancer

Crusher Rotor Balancing: Optimize Efficiency, Reduce Vibration, and Enhance Safety Introduction Crusher machines are industrial workhorses, but their heavy-duty operation takes a toll on components. One critical aspect of crusher maintenance is crusher rotor balancing. A well-balanced rotor is essential for smooth operation, reduced wear and tear, optimized efficiency, and overall safety. Let’s dive into the benefits and process of crusher rotor balancing. Benefits of Crusher Rotor Balancing Vibration Reduction in Crushers: The Key to Smooth Operation Unbalanced rotors are a primary cause of excessive vibration in crushers. This vibration can damage not only the crusher itself but also surrounding Read more…

Hydraulic pumps balancing

Pump Balancing: What You Need to Know Pumps are an integral part of many systems, from household to industrial applications. They ensure the circulation of liquids and gases, supporting various processes. However, imbalance in a pump can lead to vibration, noise, reduced efficiency, and premature wear of components. This article will discuss what pump imbalance is, why it occurs, the problems it causes, and how to address it through balancing. What is Pump Imbalance? Pump imbalance is a condition where the mass of the rotating parts (impeller, shaft) is unevenly distributed relative to the axis of rotation. This results in Read more…

Electric motors rotors balancing

The Issue: Balancing Rotors After Repair Enterprises specializing in electric motor repair often face a daunting task: achieving precise rotor balancing following the repair process. The implications of not balancing a rotor correctly are far-reaching, from escalated vibration levels to eventual mechanical failure. This article elaborates on a budget-friendly method that involves specialized balancing equipment and a straightforward stand design. Why Balancing Matters Balancing is far from a mere quality check; it’s an operational imperative. A rotor out of balance can result in: Heightened Vibration: Leading to accelerated degradation of motor components. Inflated Energy Use: Unbalanced motors consume extra energy, Read more…

Assembled vacuum pumps rotors balancing.

Introduction At the factory, with our assistance, stands have been developed and implemented for the balancing of assembled rotors in high-speed vacuum pumps. These rotors must meet stringent quality requirements for balancing, adhering to the first-class standards as per GOST 22061-76, given that their operating frequency ranges from 42,000 to 60,000 RPM. Technological Process First Stage: At this stage, when the rotation speed of the rotor does not exceed 8,000 RPM and the rotor remains rigid, the primary components of its force and torque imbalances are compensated for. With our devices, a stable residual vibration level below 0.01 mm/s is Read more…

Balanset-1 for coolers balancing

Coolers are an integral part of modern electronic devices, ranging from personal computers to specialized medical equipment. One of the key performance indicators for these coolers is their vibration and noise levels, which can directly affect the quality and reliability of the electronic equipment in which they are installed. Lower levels of vibration and noise are particularly crucial for medical equipment, where even the slightest imbalance can have significant implications. The Project Overview Recently, we received an order from a manufacturer of medical equipment to balance a batch of 100 coolers. This was a high-stakes assignment, given that the coolers Read more…
