2BE1 Series Single-Stage single-role Belt Drive Water Ring Vacuum Pump

 

General


2BE1 series liquid ring vacuum pump is the single-stage,single-role which we produce follow
the foreign advanced technique, it have no friction surface, no lubricating oil, have tighten
structure, reliable operation, wide model range, etc, mainly use to suction gas-free particles,
normal water ad the working medium, also can use the acid, alkali as the working liquid. The
range of tolerance is 4.8~450m3/min, ultimate suction pressure is 33mbar or 160mbar,
efficiency is 40~60%, is widely used to electric,industry,medicine,coal,paper making,rolling
cigarette,making sugar, etc.
2BE1 series have 15 different types, each have 5-7 speed selection, and each have three
pattern matching as motor direct, reducer and belt transmission. (Fig1, 2, 3.)

Working principle, design feature and structure
1 , working principle
Impeller install inside pump bode which arranged off-centre, inject a certain degree of water
before pump startup. Water engender a liquid ring in the pump interior under the centrifugal force
when impeller rotary, both at the end of distribution and leaves form a sealed cavity; the course
of fore 180 turn (cross the suction hole), so the space extended gradually between impeller and
vane, suction port imbibes air. The course of next 180 turn (cross the exhaust hole), space
dwindle gradually between impeller and vane, air get out by exhaust hole. (fig4).

In order to maintain constant water liquid ring, you should supply water continuously during pump
operation.

2 , design feature
2BE1 series liquid ring vacuum pump is adopt to the structure of shaft face suction and
exhaust holes. Single pump mainly have spare parts including pump body(oval),impeller,
spindle,transmission side splitter,non-transmission side splitter,side cover,automatic drain
valve, etc, (fig5). Impeller sets together with spindle, side cover separate with splitter, to meets
the different requirements of users, we install an observation hole and pump body can be
rotating.

As type 30-70 of 2BE1 liquid ring vacuum pump, its spindle adopt biaxial stretching, which
means one motor can connect with two or four liquid ring vacuum pump working at same time.
Users can choose side connect or top connect by themselves(fig6),also can choose outside
water supply to stuffing

3 , structure
3.1, impeller: we can divide into pieces of casting and welding according to ultimate suction
pressure. Generally speaking, impeller structure with number”3”as (103-403) is casting, with
“5”as(355-705) is welding.
Impeller material can choose QT40-17, ZQAL9-4-4-2, 1Cr18Ni9 or 1Cr18Ni12Mo2Ti
according to user need.
3.2, shaft: 2BE1 10-25 generally choose 2Cr13, 2BE1 30-40 made of steel 45#,2BE1 35-70
choose 42CrMo.
Shaft seal can choose stuffing seal or mechanical seal, adopts chromium steel sleeve to prevent
from damage by the shaft friction.
3.3, pump body: be oval shape, made of steel C3. Also can use 1CrNi12MoTi in special condition,
pump body can be rotating.
3.4, splitter: 2BE1 10-25 made of HT200,2BE130-70 made of steel C3, also can instead by
1Cr18Ni12Mo2Ti by user.
3.5, side cover: made of HT200,also can be Ni-Cr iron or stainless steel, there have the
automatic drain valve, be convenient to outflow the extra water, there also have the inspection
cover to inspect working situation.
3.6, spare parts of bearing: there is a cylindrical roller bearing at transmission side and
non-transmission side, radial force to bearing, besides, there is a ball bearing to the heart in the
non-transmission side, subject to shaft force.
3.7, automatic drain valve: made of HT200, can automatic drain extra water, be working better.
3.8, coupling: transmit power.
Pump disassembly and disassembly
Pump disassembly including preparation,disassembly, and checking later.
1, preparation
In order to disassembly successful, to maintain the integrity of equipment and safety, must
prepare well.
1.1, packing, cut down any relevant electric. (details according to packing of rotary method.)
1.2, getting tools ready, as wrench,hammer,pipe clamp.
