£²¡¢Installation and regulation
£¨£±£©Check whether the seals of inlet and outlet
of high-shear dispersing and emulsifying machine
are good, whether there are sundries, scrap metal
or other materials that are bad for the equipment
in the machine body.
£¨£²£© Check whether there is damage of motor and
the whole machine in the course of transporting
or leaving factory, install safety touch electric
device at the time of connecting power switch.
£¨£³£© Clean up the craft pipeline before inlet and
outlet of this equipment connect to it, connect
to this machine in condition that there is not
any welding dregs, scrap metal, glass scrap, quartz
sand or other materials that are bad for it.
£¨£´£©The RH piping type equipments should be installed
in the nearest part of container, for example,
the bottom of container. The pipeline must be
simple and direct, use syphone as little as possible
so as to reduce resistance of materials in the
course of circulation.
£¨£µ£© The installation position of WRL intermittent
type equipment should be vertical comparing with
the container, the seal must be fine if installed
slantways, it should be dampproof, dustproof,
moistureproof and explosion-proof.
£¨£¶£© Before starting, turn the principal axis,
the feel should be even, flexible, without other
friction sound or abnormal sound.
¡®£¨£·£©When installing, inlet and outlet pipelines
of SRH piping type equipment should adopt fast-installation
type hoop union structure.
£¨£¸£© Start up power device after finishing above
tasks, be on and off repeatedly to examine whether
the rotation direction of motor is in accordance
with rotation symbol of principal axis, reversion
and racing are strictly forbidden. If everything
is normal, the machine can be delivered to use.

£´¡¢Use and maintain
£¨£±£©For SRH piping type equipment, connect
mechanically sealed cooling water before starting
machine, while cutting off the cooling water after
shutting off the machine. Use running water to
act as cooling water. Pressure of cooling water
should be no more than 0.2Mpa. Make sure the materials
are in the cavity before starting machine, besides,
never operate under the condition that there isn¡¯t
any material to avoid racing, which may cause
burnt of mechanical sealing parts because of high
temperature or affect service life. Equip hose
for inlet and outlet connections of cooling water,
the inner diameter is ?5mm rubber tube.
£¨£²£©Start up the motor after the mechanically
sealed cooling water is put through, do make sure
the rotation direction of motor should be the
same as the rotation symbol of principal axis
before operating, reversion is forbidden!
£¨£³£© When using the machine, fluid material must
be continuously added or keep a certain volume
in the container. In order to protect the equipment,
racing should be avoided to prevent materials
producing high temperature or becoming solidification
in the course of working, racing is strictly forbidden!
£¨4£© Generally speaking, transport materials into
SRH piping type equipment through, the materials
must be continuously supplied to keep their fine
fluidity. When the fluidity is relatively bad
and the viscidity is no less than 4000CP, transfer
pump should be equipped at the inlet of SRH piping
type equipment, the pressure of pump is 0.3Mpa.
Choose the pumps such as rotary lobe pump (cam
rotor pump), the flux range should be matched
with that of selected piping type emulsifying
machine. (Should be larger than min flux value,
and less than max flux value)
£¨5£©Scrap metal or sundries, which are hard or
difficult to crush, are strictly prohibited in
working cavity for fear that working stator, rotor
and equipment are destructively damaged.
£¨6£© Stop and examine immediately in case there
is abnormal sound or other failures in the course
of operating, restore it after eliminating them.
Clean out the working cavity, stator and rotor
after shutting off.
£¨7£©SRH piping type equipment such as craft working
cavity can be equipped with heat preservation
layer additionally to cool down or heat up materials,
put through cooling liquid or heat-transfer oil
before starting the machine. Working pressure
of heat preservation interlayer should be no more
than 0.2Mpa£¬ when the processing has temperature
requirements (for example: pitch), it must be
heat up or cool down to normal working temperature,
jigger and start it.
£¨8£© When the equipment is used in flammable and
explosive working environment, corresponding grade
of explosion-proof motor should be used.
£¨9£© Make sure to clean up the equipment after
finishing production to maintain working efficiency
of stator and rotor and to protect the function
of mechanical sealing even more. Design and install
a set of cleaning circulation device nearby the
equipment¡¯s periphery if necessary.
£¨10£©According to the mediums, clean out the filters
of inlet and outlet regularly to avoid reducing
inlet volume of material and affecting production
benefit. The materials entering working cavity
must be fluid, powder material and conglomerated
materials can not enter it directly, or they will
damage the equipment because of block.
£¨11£© Examine stator and rotor regularly, and replace
related parts and components in good season if
the abrasion is too bad, so as to ensure dispersing
and emulsifying effect.
£¨12£© If there is liquid leakage phenomenon at
the shaft in the course of SRH piping type equipment¡¯s
operation, regulate the pressure of mechanical
sealing after stopping. (note: give detailed introduction
in operating instruction of mechanical sealing)
£¨13£© Draw up corresponding safety production and
operation regulations before using the equipment
to guarantee the safety of operators and the equipment.
Users should set safety protection system in electrically
controlled system, with fine and reliable grounding
device of electrical equipment and motor.
5¡¢Disassembly and installation of equipment
Disassembly
£¨1£©The disassembly instruction takes
SRH piping type as example (the main body is the
same as WRL intermittent type, so it is omitted),
refer to sketch map of SRH piping type product,
remove the coupling part before disassembling
to prevent working scene disturbing disassembly.
£¨2£©Loosen coupling bolt on stator £¨1£©,
pull it horizontally after loosening. Note: be
careful, not to bump stator tooth and rotor body
to avoid damage of stator and rotor.
£¨3£©Insert ¨ª10 round steel into disassembly
and assembly technological hole of principal axis
£¨6£©, loosen the cover-shaped nut on the principal
axis with spanner, take down rotor £¨2£© and regulate
axial sleeve.
£¨4£©Disassemble the coupling bolt on connection
bracket £¨4£© and crust body (working cavity), take
down crust body £¨3£©.
£¨5£© Disassembly and assembly
of mechanical sealing (mechanical sealing part)
£¨5£©refer to: operating instruction of mechanical
sealing.
£¨6£©Loosen the set bolt on the
motor shaft, knock down the principal axis and
the equipment is disassembled completely.
