B.The structure is explained
2 X type of series of vortex sheets vacuum pumps, Its structure to utilize and
lean towards heart install, Separating the stator into two jobs, volume of one
side of vortex sheet expands and sucks the gas constantly, Side volumes dwindle
constantly, gas compress reach atmospheric pressure discharge through the air
bleeding valve, Operate it and turn and repeat 2 times each time while being
above-mentioned. Pump pairs of grades of structure Model X vortex sheet type
vacuums, when suck pressure relatively high, height exhaust at the same time by
each, It suck by pressure it is relatively it is when being low,breathe in enter advanced is after compressing at
mouth at gases through in enter by rudimentary at angry dishes wallses, After compressing again, discharge from the
rudimentary air bleeding valve . When the pump has angry town valves, allow and
release, contain a small amount of vapor,etc.
can gas of the vapour of congealing nature. X-2As,,,,
pumps partial structures from head to foot 8 As As,
height adopt protruding form of rotating who groove bind s by grades of rotor.
X-30As, for inclining partial structures, rudimentary rotor a form of rotating
at senior rotor s A pumps, And adopt the pump and cool
the heart openly in the shell, it is warm and low to have the pump to cool, the
characteristic of limit with low total pressure.
C.The use and scope of application
1��Pump use and release
Model Xs to airtight containers except that gas obtain the basic equipments of
vacuum one of. But use alone, can be as a grade of pumps ago that pressed the
pump, spread the pump, molecule pump etc. again. Use in vacuum smelt, vacuum weld , vacuum flood, plate membrane, vacuum casting, vacuum
dry and chemical industry pharmacy, The electric vacuum device waits for the
vacuum homework of industry.
2��Pump can have been within the range of 5~
3��Pump suitable for and release except that suck oxygen
too high, a poisonous one, have explosibility, have
and corrode function, get up chemical reaction to pump oil to metal, And the
gas with small and roundish thing and dust, is not
suitable for sending the gas from a container to another container either, Make
and send the pump to use.
4��The continuous working time under the import pressure
of the atmosphere of 6000 Pas of pump can't exceed 3 minutes , Cause the pump
to be damaged so as not to gush out the oil or lubricate badly .

E.It is explained that install
1��Install at pumps it is at
ground it is firm place more durable,around leave by
abundant leeway, Easy to check, safeguard, maintain.
2��Pump keep ground level under the base, base propose cushion
shock attenuation rubber or cast installing with the bolt by quadrangle place,
Guarantee that the pump turns round steadily, vibration is small.
3��Pump join pipeline should have been airtight and
reliable, adopt metal join airtight cushions adopt and able to bear oil rubber
by pipeline to little pumps with a systematic one, Adopt vacuum in charge of
and join by glue, pipeline smaller than pump requirements of breathing in by
pipe diameter to little pumps, And require pipeline short and few elbows .
(Should be removed and weld dregs in the pipeline while welding the pipeline,
forbid welding dregs to enter pump. )
4��In joining the pipeline, the user can install the
valve and vacuum to count on the air inlet of pump , Can check the limiting
pressure of the pump at any time.
5��It connects according to motor sign regulation and
earth connection and install suitable the fuse boxes and hot relayses of specifications.
6��Pump set up an electric circuit running-in, it draws
lower electrical machinery belts confirm that the pump turns to and accord with
stipulating that the direction can come into operation , In case the pump
overturns and gushes out the oil. ( turn to and point out the direction
according to the protection casing )
7��For having pump of cooling water, put through the
cooling water according to the regulation.
8��While installing the electromagnetism valve such as
the pump mouth, the movement at the same time that valve and pump should .
9��When the pump is arranged and gives vent to anger the
body and influence the working environment, install and meet pipeline guide at
gas vent from installing and answer oil fog filter.
F.The operation instructions
1��Close the valve on the pump
2��The pump with cooling water is put through the
cooling water .
3��Nearly regulations turn to a belt pulley of hand and
count the circle , enter the oil in pump in the fuel tank, Guarantee that it is
difficult to start to gush out the oil. (Very in winter, the oil is glued
greatly, it is great to start load, So ask pay
attention to).
4��Starting the motor, the pump is started and turns
round, watch the window of the oil, Check the oil level. The oil level should
mark the centre in the oil , the oil level is on the high side, will cause and
gush out the oil; The oil level is on the low side, will cause and lubricate
badly , the limiting pressure of the pump can not be reached out the factory
index .
Refuel, set free oil see pump for details indicator by position. Turning on the
valve on the pump slow, the system begins to work.
When working, oil hardly see oil by window, enter pump body pump, The oil level is subject to that the pump is while turning
round.
5��To enter water should regard exceeding
6��Put into and start to work in the pump after when
environmental temperature is lower than
7��Warm with warm to deduct environmental temperatures
should exceed ��s , strengthen and ventilate and dispel
the heat or increase cooling water flow oil pump.
8��Enter temperature higher than ��s when making the pump not to be warm and too high, must take
measures to cool the gas by one.
9��When sucking the gas has influence to the oil of pump
or the pump, should hold a suitable filtration device before the pump mouth.
10��Should turn on the angry town valve and work for
half an hour when the pump is smoked except that when can contain the gas of
congealing nature a small amount of , start the pump, Can lengthen the oil
service time of pump .
11��Pump as pump, at the gas with small and roundish thing, dust, should be loaded with a suitable
filter in front of the pump mouth.
12��It imprisons pump close the valves of pump with
isolating systematically, then parked the pump first, Twist the urgent air town
valve, in case the oil spill and then, close the cooling water at last. There
is occasion frozen in winter should put the cooling water in the net pump , in case pump is frozen to crack.
The note: The limiting pressure of this series of pumps mean the pump and does
not take over any containers , the pump reaches steady warmly, At person who
compress vacuum count at pump mouth examine stability that get most low to
divide into the pressure. The total pressure of limit is only for reference.
General situation, the single pump turns round for half an hour and reach the
limiting pressure .
G.Safeguard and maintain
1��Often check the oil level seat, must change to make
it fulfil requirements when being not in accordance
with regulation. That when the pump turns round, the oil
level marks the centre to the oil serves as the standard.
2��Check oil quality situation often and find oil go bad
and change new oils in time, guarantee it is normal for pump to work.
3��Whether can change the time limit of the oil
according to the actual service condition and could satisfy the situations,
such as performance request,etc. to
consider , Decided as one sees fit by the user. General new pumpses,
smoke except that at the clean dry gases, propose. After can't see the ferrous
metal powder in the oil, very proper extension will change the time limit of
the oil afterwards.
4��Under the general situations, pump work one hour go
on and overhaul, check Chinese catalpa glue airtight pieces of degree of
wearing out, Check air bleeding valve fracture and clear up and precipitate by
one. Washing the part in whole pump, for instance rotor, vortex sheet, spring,etc.. Generally wash with
the petrol, and dry. Let's dry the cloth with doing after pieces of washing of
rubber.
Should handle with care and damage carefully while assembling
to wash.
5��Clear up Guan Zhong equally
conditionally, guarantee that the pipeline is unblocked.
6��It carries on test run after reassembling generally
air transport must transfer one hour to and transfer to 2 of oil, Because will
leave certain quantity and exchange the volatile matter in the pump while
washing, after turning round normally, Put into the normal work again.
7��This series of pumps oil adopts SY 1634 - 70 1#
vacuum oil of pump.
