Vibration Measurement for Slide and Roller Bearings |
| |
| VCS - Vibro
Control Solutions™ replaces nonexisting monitoring staff on-site. All impressions
this skilled operator heard and felt, VCS provides as a processable 4...20mA signal.
|
|
| VCS ist a universally applicable measuring system
for machine vibrations by kmo turbo. It consists of a robust, easy-to-install
accelerometer (M12-thread) and a transducer in a DIN rail housing. VCS can be
used for high-speed units (e.g. turbines) as well as for low-speed units (e.g.
fans for cooling towers). Different evaluation modes of the transducer (average
or envelope) allow the use for both roller and slide bearings. VCS offers the
option of a self-test for sensor and transducer. The range of applications is
not limited to new plants. VCS is predestined for the retrofit of existing machines.

| >> "Flight
Recorder" for Industrial Machines |
| |
| The perfect add-on for machine
diagnosis and vibration analysis |
|
| Causes of malfunction can be detected extra reliably
by comparative measurements. kmo turbo offers a "flight recorder" for industrial
use which next to conventional machine protection monitors particular faults and
damage causes individually. By this, the safety degree of monitoring increases.
Simultaneously all relevant data of the actual machine condition are available.
Preventive countermeasures can be planned and carried out in time. Besides vibration
signals any expressive indication concerning the machine condition as speed, efficiency,
temperatures and process values are continuously recorded and stored. So after
each trouble the reason and the progress can be easily detected. Permanently calculated
FFT- spectra of up to 8 measuring points enable helpful information to find out
the cause of vibration troubles. With a visualising software the process data
can be shown in informative graphics. |

Detect "water in oil" and leakages without delay! |
| |
| The qualified
operator used to control his machine regularly. Checking the oil system hourly
he was able to detect even the smallest leckage and fixed it immediately. In times
of drastic staff reduction due to automation, the disappearance of the human operator
has adversely affected the quality of monitoring. In order to compensate for this,
appropriate sensors and automatic monitoring must be provided. |
|
| In
terms of controlling a lube oil system SLM - Smart Level Monitoring® by kmo turbo
can meet this task. The basic principle of this automatic and stand-alone control
is the monitoring of comparative dynamic limits (= limits which are adapted to
the normal change of level according to the current operating condition of the
machine and its oil system). The advantage is that troubles are detected without
delay and not only after exceeding permanently fixed limits. Many times a trouble
can only be connected with the cause usefully and instructively if it is signalled
immediately. Each customary level transmitter can be connected to SLM. |

Retrofit of Hydraulic Actuators to 4...20mA Control |
| |
| In the
cause of upgrading measures (e.g. the implementing of a process control system)
it is necessary to control hydraulic actuators via a mA signal. kmo turbo solves
this task with an approved concept based on standard components. |
|
| At
conventional constructions the control oil pressure is between 5 and 15 bar. For
exact positioning a pilot actuation with a mechanical position feedback is required.
Additionaly a diaphragm pressure transducer is needed for the conversion from
pneumatic to hydraulic and an I/P-converter for the conversion from electric to
pneumatic. All those components are maintenance and fault sensitive. It is getting
more and more difficult to get skilled personnel for maintenance even from the
manufacturer. The concept by kmo turbo gets rid of the said components and allows
direct electronic control after short retrofitting and commissioning time. |

Anti-Surge Control and Surge Protector |
| |
| Persistent surging of
a turbo compressor will lead to massive damages. The breakdown of flow can have
disastrous effects on the following process. Therefore compressors should be equipped
with two independent systems, an anti-surge control and surge protection.
|
|
| The
anti-surge control holds up stable operation. While approaching the surge line,
the flow of the compressor is kept at the lowest possible value by opening a by-pass
valve. If the controller failes due to external circumstances the compressor surges.
Only in this case the surge protection is activated. It is supposed to prevent
persistent surging by a suitable control intervention. The Anti-Surge Control
and Surge Protector by kmo turbo stand out from conventional control concepts
by numerous practical functions. In particular they are predestined for the retrofit
of existing machines. |

Wear Indicator for Wet Seals |
| |
| Frequently there is a direct connection between seal
damage and a change of operating parameters. By monitoring the gradient a failure
is signalled immediately. This allows to draw direct conclusions regarding the
cause of the trouble. |
|
| The leakage fluid under pressure is usually seperated
by condensate drains and led into a collecting tank. Condensate drains are fault-sensitive.
Malfunction can lead to damming of the liquid. Thus dirt from the tank pollutes
the seal and accelerates the wearing process considerably. A faulty drain can
also lead to dangerous gas blow-off. kmo turbo has developed a control unit for
optimized draining with intelligent monitoring functions. For the first time malfunction
and its negative side effects can be detected right in time. |
