GlobeCore High Vacuum Degasifier CMM (UVM) 4/7
GlobeCore Mobile High Vacuum Degasifier CMM (UVM) 4/7
mounted on a roadworthy trailer with torsion suspension, appropriate reflectors
and tail lights and capable of being towed at speeds of up to 80km/h. It will be enclosed with water proof metal covers (protection class IP45) and have a
mechanism to secure plant in stationary position while in operation. Maximum noise level emitted by the unit will be below 80 db.
Production capacity of the unit will be between 1000 L/H and 4000 L/H and
provide:
• Removal of Water from 100 ppm down to 10 ppm and from 50 ppm
to 5 ppm in a single pass and down to 3 ppm after 3 passes (ASTM method
D-1533).
• Reduction of Gas content from fully saturated with air (10 to 12% by
volume) to less than 0.1 % (ASTM D-2945).
• Removal of Particulate Matter to 5 micron
• Improvement in dielectric strength up to 70 kV
COMPONENTS DESCRIPTION:
I. VACUUM SYSTEM
CMM (UVM) 4 will have the following vacuum facilities:
This Oil Purification plant will have horizontal Vacuum Column with
Coalescers.
Vacuum Chamber Vessels and all internal parts are made of carbon steel and
feature Coalescers, Sight Glass, Oil Level Controller and Vacuum Gauge.
Vacuum Chamber’s rigid design makes it suitable for stationary and mobile
installation. Appropriate flexible connections are provided to the outlet
pump and inlet pump to minimize negative effect of vibration during plant
operation and transportation.
Vacuum Chamber
1–Oil Inlet
2–Vacuum Pump Connection
3–Coalescers
4–Oil Outlet
5–Level Sensor
6–Sight Glass
Coalescers - four built-in coalescers are provided for the maximum
exposure of oil to the effect of vacuum. Due to reduced pressure dissolved
water and gases are vaporised through secondary chamber and filter into
atmosphere.
Secondary Chamber (Oil Trap) - serves as safety feature to ensure that
no oil is pulled into the vacuum pump. It is equipped with oil level sensor
which will activate the alarm in case of oil presence.
Oil Level Controller - consists of three capacitive probes provided to
maintain required level of oil in the Vacuum Chamber.
Vacuum Gauge - is provided to monitor Vacuum level in the Vacuum
Chamber. Vacuum gauge will be absolute type with display in mbar.
Vacuum ports – vacuum connection is provided to pull vacuum on
transformer.
Sampling Ports – inlet and outlet oil ports are provided for incoming and
processed oil.
III. OIL HEATER
The electric oil heating facility will be provided in 2 stages offering a total
of 48 kW of power. A low watt density encapsulated heating elements (1.2
W/cm²) are used to prevent heat degradation of oil. The Heater is controlled
by electronic temperature controller.
IV. INLET AND OUTLET OIL PUMPS
Inlet Oil Pump: “Calpeda” Centrifugal Pump with power consumption of
4 kW and maximum capacity of 14 m³/h.
Outlet Oil Pump: “Calpeda” Centrifugal Pump with power consumption
of 3 kW and maximum capacity of 10 m³/h.
“Calpeda” Centrifugal Pump
Oil heater
1 – oil heater;
2 – cold oil inlet;
3 – hot oil outlet
V. FILTERS
A 90 micron Mesh Strainer is provided to remove large particles that could
cause damage to the Inlet Pump. 5 microns Coarse Filter is installed on
entry to the Vacuum Chamber. Oil receives its final treatment by passing
through the 1 micron Fine Filter designed to remove 99.9% of particles
larger than 1 micron.
VI. ALARMS AND INTERLOCKS
GlobeCore’s CMM plants feature the following safety devises which ensure
simple and reliable operation and will safely shut down the system in case of
any alarm situation:
High Level Alarm - will alert plant’s operator by activating sound and light
alarms and shut down the system safely should high level of oil persist.
Low Level Alarm – interlocked with the inlet pump low level alarm will
safely shut down the plant in case of insufficient oil level.
Flow Sensor - only activates the Heater when oil flow is detected.
Overloads – all motors are protected by overloads.
Alarms – sound and light alarm with silence button will alert plant’s
operator of any emergency situations.
Foam Sensor - prevents excessive foaming.
Coarse and fine Filters
1–Oil Inlet
2–Oil Outlet;
3–Drain Valve
4–Air Valve
5–Manual Air Discharge
6–Magnets
7–Clamp
8–Filter Cartridge
VII. INSTRUMENTATION AND CONTROLS
Control panel is a dust proof enclosure (protection class IP 54) featuring the
following elements:
Control cabinet general view
Control and measurement instruments.
Column’s residual pressure is controlled by electronic vacuum controller Autonics. Oil heater is controlled by following: - thermostat for oil heater disconnection if oil temperature is above 90 ºC;
- flow relay for oil heater disconnection when no oil flow is supplied through oil heater;
- temperature controller for oil temperature at heater outlet; - manometers indicate contamination of fine filters and pressure at unit outlet;
- level sensors control oil level in vacuum column. - foaming sensor controls foaming level in the vacuum column.
