Myself-1 typeTⅡ

Dynamic balancing with easy operation supports on-site work.

Overview

Myself-1 typeTⅡ performs quick and accurate balancing
(balance correction/balance adjustment) .
The field balancer is easy to use and does not require technical experience.

Performs high-precision balance correction of rotating equipment such as pump, blower, impeller like fan,grinding wheel, shaft, or spindle.
This is a long-selling product that has been adopted by a wide range of customers, including manufacturers of rotating machinery,maintenance companies for rotating machinery, and processing companies that use rotating machinery for machining.

You will be supported or navigated by the interactive interface with icon display and a variety of supportive functions. It will be easy balance correction for a first-time user.

機器構成

What is Field Balancer?

Field Balancer performs field balancing.
Measures imbalance by dynamic balancing on site for a variety of rotating equipment.

Detects imbalance while machine is rotating with workpiece assembled.
Imbalance including the fit tolerance from the assembly can be adjusted all together, which suppresses the vibration of the machine.

Dynamic balancing

Detects the weight and position of imbalance from the vibration synchronized with rotation frequency.

Features

Realization of highly accurate balance measurement and correction

A high-sensitivity vibration sensor capable of detecting amplitudes as small as 0.001 μm and our original noise filter that cuts peripheral noise and extracts signals necessary for balance measurement.
This enables highly accurate balance measurement and correction.

Easy to operate for anyone

Improved usability with 2 types of operation of touch panel and key switches. Interactive interface with icon display.
Automatic operation starting to measure vibration when reaching at a set rotation speed.

Supportive functions for balancing

♦Vibration monitoring function
(displacement, velocity, acceleration)

Rotation speed, vibration value, and vibration phase angle can be monitored.
It can be used to determine the X, Y, and Z (Horizontal, Vertical, and Axial) vibration state of the balance measurement target and how much it is swinging in either direction.
It is effective to check the vibration changes before and after the balance correction (whether the vibration in three directions has dropped properly) and to check the changes over time.

♦Vibration waveform monitoring function

This function is used to check the vibration waveform captured from the acceleration sensor.
The OVA (vibration waveform taken from the acceleration sensor) and BP (vibration waveform after passing through the band pass filter) can be checked respectively.

♦Simple FFT function

FFT (frequency analysis) of the vibration waveform taken from the acceleration sensor can be performed.
This function can be used to determine whether the cause of vibration is unbalance or something else (bearing failure, etc.).
If imbalance is the cause, the spectrum will appear at a frequency corresponding to the rotation speed of the measurement target.

♦Display of the installation position of the balance weight

This function allows the user to visually check the mounting position (angle) of the balance weight (correction weight) by graphically displaying it.
This function allows anyone to read the angle in any direction relative to the direction of rotation of the measurement target without error.

♦History check function for corrected data

With the history function, you can check how the vibration condition has changed by attaching temporary weights (test weights) or modified weights and at what position and for how much weight.
The history function allows you to check how the vibration condition has changed.

etc.

Selectable power source type to fit the usage environment

Newly lined up is DC5V power supply of mobile battery in addition to AC power supply.
You can select a type of power source which fits your usage environment.
No need of external power source with the battery, and you can use even for long hours with multiple batteries fully charged.

Battery included in the package is for continuous operation of 9 hours or more. ※Model of DC5V is compatible with AC adapter (Input: AC100 to 240V) and can be supplied from AC outlet as well.

Realization of highly accurate balance measurement and correction

♦Multi-speed balance function

This function reduces overall vibration in a given speed range. This function is suitable for measuring the balance of blowers and machining centers with a wide range of operating speeds.

The figure below is an example for reference, but even for rotating equipment with large vibration around 7,000min-¹ and 11,000min-¹ in the initial state (red line), multi-speed balancing can reduce vibration over a wide range (green line). The figure below is an example for reference.

♦Memory function for influence coefficient

When measuring the same rotating object repeatedly on a regular basis, or when continuously measuring the same product for mass production, this function memorizes the effect of temporary weights and allows continuous balancing without installing temporary weights.
This function enables continuous balancing without the need to install temporary weights.

♦Report creation function

This function outputs the measurement results as a report. This function can be used as evidence for maintenance records of rotating equipment such as blowers and pumps.
This function can be used as evidence for maintenance records of rotating equipment such as blowers and pumps, and as a work report to be submitted to customers.

♦Vibration monitoring function

This function outputs the data sampled by the vibration monitor to a PC or other device.
This function can be used as a data logger to record changes in the vibration of rotating equipment such as blowers and pumps during abnormal conditions.It can be used as a data logger.
Simple FFT analysis data can also be saved, so it can be used as an attachment to work reports submitted to customers.

♦External control function

A function that allows connection to an external device such as a PC to send commands to instruct the balancer to operate, output measurement results to the external device, etc.

♦System proposal including jig creation

We can propose a system that includes the creation of jigs (such as chucks for measuring objects and sensors for measurement) and dedicated software necessary for proper balance measurement.
We can also propose a system that includes the creation of dedicated software.

We have been using our balancers to measure the balance of rotating equipment for many customers. The know-how we have gained through this process has helped us improve the quality and performance of our products.

We also provide support (including demonstrations) for customers who have purchased our products. We also continue to support and contribute to customers who have purchased our products by providing support (including demonstrations) on balance measurement.

Please do not hesitate to contact us if you have any problems, even if they are trivial.

Example of installation

Single-plane balancing for rotor

Attach the vibration sensor at one location of the bearing unit to measure the vibration.
Balance is corrected on one side of the rotor.

Dual-plane balancing for rotor

Attach the vibration sensor at two locations of the bearing unit to measure the vibration.
Balance is corrected on both sides of the rotor.
