G Type Self-Priming Canned Motor Pump
DESCRIPTION
Self priming type:The suction inlet of the pump is much higher than
the center of the impeller. After stopping the pump, when there is
no liquid in the suction pipeline, the impeller and the enlarged
pump chamber are always filled with liquid. When restarting, there
is no need to fill water, and the pump can work. Self priming pumps
are particularly suitable for extracting liquids from underground
containers.
It adopts international standard design, the maximum operating flow
is 1200m3/h, the maximum head is 600m, the temperature range is
-120-350°C, and the maximum pressure of the system design is 20MPa.
The drive of an ordinary centrifugal pump is to connect the
impeller shaft of the pump with the electric shaft through a
coupling, so that the impeller and the electric motor rotate
together and work. However, a Canned MotorPump is an unsealed pump,
and both the pump and the driving motor are sealed in a pressure
vessel filled with the pumped medium.
This pressure vessel only has a static seal and is equipped with a
wire group to provide a rotating magnetic field and drive the
rotor. This structure eliminates the rotary shaft sealing device
that traditional centrifugal pumps have, so it can achieve complete
leak free operation.
ADVANTAGES
(1) Long service life, automatic hydraulic thrust balance system
combined with silicon carbide bearings to obtain high service life;
(2) High efficiency, optimized motor design and high-efficiency
hydraulic research, achieved excellent energy efficiency;
(3) High reliability, advanced processing technology, high-tech CNC
equipment and perfect testing to ensure the stability of product
performance;
(4) Monitor bearing wear to realize online monitoring and automatic
control;
(5) Secondary sealing to ensure the safety to the environmental
even in the accident situation.
FEATURES
The Principle and Structural Characteristics of Shielded Pump
The drive of an ordinary centrifugal pump is achieved by connecting
the impeller shaft of the pump with the electric shaft through a
coupling, allowing the impeller to rotate together with the
electric motor to work. A cnanned motor pump is an unsealed pump,
and both the pump and the driving motor are sealed in a pressure
vessel filled with the pumped medium. This pressure vessel is only
statically sealed, and a set of wires is used to provide a rotating
magnetic field and drive the rotor.
This structure eliminates the rotary shaft sealing device that
traditional centrifugal pumps have, making it completely leak free.
The canned motor pump connects the pump and motor together, and the
rotor of the motor and the impeller of the pump are fixed on the
same shaft. The shielding sleeve is used to separate the rotor and
stator of the motor. The rotor operates in the medium being
transported, and its power is transmitted to the rotor through the
stator magnetic field.
In addition, the manufacturing of canned pumps is not complicated,
and their hydraulic end can be designed and manufactured according
to the structural types and relevant standards and specifications
commonly used in centrifugal pumps.
Precautions for using Canned motor pump:
1. During normal operation, the outlet valve should not be closed
tightly and should be kept slightly open to prevent air blockage in
the pump.
2. It is strictly prohibited to operate without liquid or for more
than 1 minute to prevent damage to the motor and bearings.
3. It is strictly prohibited to run in reverse for more than 1
minute, as reverse operation may cause abnormal wear of the
bearings.
4. It is strictly prohibited to operate under cavitation
conditions, otherwise it may cause early wear of the bearings.
