Vbrating and vproconsole dynamic equipment, measurements of vibrations

Modern technological processes associated with the use of a large number of variety of rotor machines and mechanisms, failsafe and reliable operation which determines the efficiency and competitiveness of production the enterprise as a whole. To ensure the reliability of machines with nodes rotation, it is necessary to vpromaster and vproconsole dynamic equipment that is relatively simple to implement and gives reliable results assessment of technical condition of dynamic machines.

1.Vproconsole dynamic equipment the stationary parts of the machines (GOST ISO 10816-1-97) is required and the simplest the inspection of the washing machine that does not require a large number of measurements, complex analysis and is implemented using simple and inexpensive vbroker (e.g. BALTECH VP-3405-2, BALTECH VP-3410 or "PROTON II Balance"). Vproconsole dynamic equipment mainly includes measurement of vibration velocity RMS or vproperties scale in the range 2-10 ÷ 1000 Hz or 10 ÷ 2000 Hz. But measuring only low frequency vibration (up to 2000 Hz) is not always sufficient to assess the current state and forecast resource dynamic machine. For example, control of low-frequency vibration does not allows you to identify the development of dangerous defects in the bearings up to the stage of their destruction. Therefore, together with the standard control low-frequency vibration recommended control pcfactory (the ratio of peak value to SCD) of the high frequency component of vibration in the range of 6-10 kHz and above (up to ultrasound).

With this in mind, vproconsole dynamic equipment only for low frequency vibration usually applies to:

• periodic monitoring of dynamic equipment external regulatory bodies or services;

• upon acceptance of the equipment after fabrication, repair and installation on-site installation;

• for the continuous monitoring of the most critical equipment in transient modes of operation when elevated vibration can lead to their failure.

As mentioned above, vproconsole dynamic equipment can be implemented using the simplest vbroker BALTECH VP-3405-2, BALTECH VP-3410 or more complex the vibration meter-balancer "PROTON-Balance-II". In addition to affordability, data the devices do not require a highly skilled operator and, in many ways, this is what as well as good performance due to their special demand among consumers.

2.Vbrating dynamic equipment

The results of periodic measurements of vibration allow not only to compare them with the maximum permissible values, and to identify their monotonic or abrupt changes over time (trends) in the case monotonous changes to predict the future behavior of the monitored parameters vibration. This is the task of the dynamic vibration monitoring equipment, that includes regular measurements of vibration level at least several times a month.

We have already mentioned that knowledge only SKU vibration velocity in the standard range of frequencies (10 ÷ 1000 Hz) failed to provide sufficient answers about the state of the dynamic machine and vibration monitoring dynamic equipment necessary to carry out additional monitoring of other parameters of the vibration, I have the closest relationship with the state of the machine and also to control and newbourne parameters (temperature, power, flow, etc.) that reflect the current state of the machine or its components.

The number of Real indicators be different and the complexity of their processing are defined by opportunities used monitoring tools: in the event a portable device is a small number of controlled parameters universal auto treatment, which needs to be adapted to the specific machine; in the case of stationary systems of vibration monitoring of dynamic equipment is virtually unlimited the number of monitored parameters with a finish adapted to the specific car.

A good example of a portable device monitoring is two-channel vibration meter-balancer "PROTON-Balance-II", which measures the vibration velocity RMS and dual scale vproperties and provides temperature control and speed of the shaft.

Vbrating and vproconsole dynamic the equipment of measurement of vibration level and vibration diagnostics of complex machinery, and mechanisms we recommend using the vibration analyser, the CSI 2140 and software VibView.

We invite to courses of improvement of qualification and retraining TOR-103 "vibration monitoring and vibration diagnostics dynamic equipment. Balancing of rotors ".
