IH Horizontal Stainless steel chemical centrifugal pump for
IH stainless steel chemical centrifugal pump instructions:
1. ready before starting
(1) Before starting the pump and the scene clean up.
(2) Check the amount of oil in the bracket is appropriate (oil
level in the oil level gauge center line 2mm or so) is good.
(3) before the coupling is not connected to check the main engine
of the steering, and the pump steering arrows, then connect the
(4) in the installation of mechanical seals or packing and coupling
can be easily turned by hand pump shaft, should be no rubbing
phenomenon, and the coupling of the protective cover installed.
(5) pump in the case of suction use, should be pumped before the
start of pumping or vacuum; pump in the case of the use of
inverted, before the application of the liquid transported by the
pump filled, the pump out of the air, shut down.
(6) Check the foundation bolts before starting. Whether the gland
is skewed, and the supply of lubricating oil and cooling water.
(1) Close the inlet and outlet pressure (or vacuum) and the outlet
valve (if there is a bypass pipe, it should also be closed at this
time.) Start the motor (it is best to start before the pump is
correct and confirm that the pump is turned correctly. ), And then
open the inlet and outlet pressure (or vacuum) meter, when the pump
reaches the normal speed, and the instrument pointed out the
corresponding pressure, and then slowly open the water valve,
adjust to the required conditions. In the case of the discharge
line is closed, the pump can work continuously for more than 3
(2) start the process to always pay attention to the prime mover
power readings and pump vibration, vibration should not exceed 0.06
mm, the measurement site is the bearing.
(3) Sealing situation: mechanical seal should be no leakage, heat
phenomenon, packing seal should be a continuous dripping state.
(1) often check the pump and the motor heat (bearing the
temperature rise should not exceed 75 ℃) and oil level fuel supply
situation. (Usually every 1500 hours after running, to replace all
the oil once).
(2) can not use the suction valve to adjust the flow, to avoid
(3) The pump should not be operated continuously at less than 30%
of the design flow, and if it must be operated continuously under
this condition, the bypass pipe should be installed at the outlet
to discharge excess flow.
(4) Note whether the pump running noise, such as abnormal state,
should be promptly eliminated or parking check.
(1) Slowly close the vents outlet valve (if the pump is used in the
case of a backflush, turn off the gate valve of the suction line)
and turn off the switch of the various instruments.
(2) cut off the power supply
(3) If the seal is used for external priming, also close the outer
(4) If the ambient temperature is lower than the liquid freezing
point, it is necessary to put the liquid inside the pump to prevent
(5) If you do not stop for a long time, in addition to the
corrosive liquid inside the pump put the net, the parts should be
disassembled clean, especially sealed cavity. It is best to remove
the pump after cleaning and re-installed, in addition to oil
anti-rust treatment and closed pump into, exports, but also
IH stainless steel chemical centrifugal pump mechanical seal
- because the mechanical seal is generally applicable to the use of
clean, non-suspended particles in the medium, therefore, the newly
installed piping system and liquid irrigation, should be carefully
rinsed, to prevent solid impurities into the mechanical seal face
and seal failure.
- in the easy crystallization of the medium, the use of mechanical
seals should always pay attention to frequent washing. Before
restarting the car, clean the crystal on the mechanical seal.
- the removal of mechanical seals should be careful not to use hand
hammer, iron and another percussion, so as not to damage the
dynamic, static ring sealing surface.
- if there is dirt can not be removed, you should try to remove the
dirt, rinse and then disassemble, so as not to damage the sealing
- before installing the mechanical seal should check all the sealing
components are invalid or damaged if any should be repaired or
- should strictly check the dynamic ring and static ring relative
friction sealing surface does not allow any minor scratches, bumps
and other defects. All other parts, including the pump body,
impeller, sealed chamber, etc. should be rushed before assembly,
especially moving, static ring end, use a clean, soft cloth or
cotton carefully wipe clean, and then coated with a layer of clean
grease Or oil.
- the assembly should pay attention to eliminate the deviation,
tighten the screws, to even tighten, obscure the skew so that the
- the correct adjustment of the amount of spring compression, pump
installed after the hand to pull the rotor, should feel the seal
spring both a certain amount of compression, but also light and
flexible to turn the feeling of no bite. Such as feeling too tight
or disk does not move, it should be appropriate to loose some.
- the external flushing of the mechanical seal, before starting
should first open the rinse solution, so that the sealed cavity
filled with sealing liquid. When stopping, stop the pump and shut
Chemical centrifugal pumps are used in the chemical, petroleum,
metallurgical, power, paper, food, pharmaceutical and synthetic
fibers industries for the transport of corrosive non-contaminated
