Kubota 7000 Diesel Generator
|
Direct Coupled
The generator and the engine are direct-coupled to ensure a more reliable power supply with minimum power loss.
A Skewed Rotor & Damper Winding
The
waveform distortion is kept to a minimum by the skewed rotor, while the
damper winding protects the generator during short circuits, regulates
voltage fluctuations during condensive loads, and withstands load
fluctuations during condensive and non-linear loads.
|
| EASE OF OPERATION |
Compact Design
The design of the LOWBOY II Series is based on the previous
compact two-pole horizontal type diesel engine generator. Even though
this series is powered by vertical type diesel engines, the height is
kept as low as the previous LOWBOY by direct coupling the engine
crankshaft with the cooling fan. Kubota also changed the location of
the package's air inlet vents to reduce the height of the internal
sound absorption duct.
Lower Noise Levels
Four separate improvements help reduce the overall noise levels.
First, the large capacity radiator successfully reduces fan related
noise by direct coupling its crankshaft with the slower-speed fan. Second, the large capacity, built-in muffler helps reduce exhaust related noise. Third, the longer air cleaner hose reduces air suction related noise. Fourth, the ideally placed inlet vent and its improved design reduce noise coming from the enclosure's opening.
|
|
Longer Continuous Operation
The LOWBOY Series' large capacity (28L) fuel tank enables
longer
continuous operation on a single tank of fuel.
Outstanding Transportability
The special forklift openings on the base of the machine, and the
one-point lifting eye enhanced transportability. A remote control kit
is also available as an option.
Access Terminals for ATS make Wiring Easy
Access Terminals for ATS (Automatic Transfer Switches / not supplied by Kubota) are located behind the control panel. |
|
|
| CAREFREE MAINTENANCE |
One Side Maintenance
Oil, fuel, battery, and cooling water are all located
on one side for easy maintenance.
Larger-Capacity Oil Pan
This helps stretching the oil change intervals,
thus reducing the overall running cost.
Direct-Coupled
Eliminated the time needed to adjust or replace the cog-belt by direct coupling the generator and the engine.
|
|
Double Element Air Cleaners
All LOWBOY generators come with double element air cleaners as
standard equipment. Ideal for heavy duty applications in dusty
environments.
|
| INCREASED SAFETY |
|
Double Circuit Protectors
In addition to the overall circuit protector, each receptacle also
has a circuit protector that will shut the engine down to prevent it
from overcurrent damages.
Output Connection Cover
This cover, on all terminal type LOWBOY, stops the engine immediately when it is opened up during operation.
Protective Covers
All moving parts of the engine's cooling fan and the generator are covered.
Automatic Shutdown System
This system automatically shuts the engine down when it senses the
engine coolant temperature rising excessively or the oil pressure
dropping below a safe level.
Starter Safety Relay
This relay prevents the starter from engaging again once the engine starts up.
