Stuffing Box NOV Mission Centrifugal Pump Parts TRW API Standard
Mission Centrifugal Pump Structure Composition
The basic structure of MISSON centrifugal pump is composed of six
parts: impeller, pump body, pump shaft, bearing, sealing ring,
stuffing box.
1, the impeller is the core part of the centrifugal pump, its speed
is higher than the force, and the blade on the impeller plays a
main role, the impeller should pass the static balance experiment
before assembly. The inner and outer surfaces on the impeller
should be smooth to reduce the friction loss of water flow.
2, the pump body is also known as the pump shell, it is the main
body of the pump. It plays a supporting and fixing role and is
connected with the bracket for mounting bearings.
3, the role of the pump shaft is to connect the coupling and the
motor, the motor torque to the impeller, so it is the main
component of the transfer of mechanical energy.
4. Sliding bearings use transparent oil as lubricant, and add oil
to the oil level line. Too much oil should seep along the pump
shaft, too little bearing should overheat and burn out causing an
accident! In the process of running the pump, the temperature of
the bearing is 85 degrees, and the general operation is about 60
degrees.
5, sealing ring, also known as leakage reduction ring.
6. The packing box is mainly composed of packing, water seal ring,
packing barrel, packing gland and water seal pipe. The function of
the stuffing box is mainly to close the gap between the pump shell
and the pump shaft, do not let the flow of water inside the pump to
the outside and do not let the outside air into the pump. Always
keep the vacuum in the pump! When the pump shaft and the packing
friction generated heat on the water seal pipe to water seal ring
to cool the packing! Keep the pump running properly. So in the
operation of the pump in the process of inspection of the packing
box is special attention! The filler should be replaced after 600
hours or so.
MISSION Centrifugal Pump Product Characteristics:
1, the use of excellent hydraulic model and advanced manufacturing
technology, improve the performance and service life of the pump.
2, because the shaft seal is made of hard alloy and fluorine rubber
mechanical seal, it can improve the reliability of pump operation
and the temperature of the conveying medium.
3, the flow part of the pump is made of stainless steel plate
stamping and welding, so that the pump can be applied to mildly
corrosive media.
4, the overall structure is compact, small volume, light weight,
low noise, energy saving effect is remarkable, easy maintenance.
5, the pump inlet and outlet are located at the same level of the
pump seat, can be directly used in the pipeline.
6, using standard motor, users can be conveniently equipped with
motor according to the needs.
7, can be equipped with intelligent protector according to the
needs of users, the pump dry rotation, lack of phase, overload and
other effective protection.
