The operating basic principle of the 3-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By way of the action of a pair of
synchronous gears, the two rotors rotate in opposite directions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the fuel in the chamber is pushed to attain the
objective of blowing.

Characteristic of our roots blower:
1. Huge adjustment of the air quantity
two. Lower Noise
3. Substantial effectiveness
4. Low energy cosumption
five. Long time lifestyle
6. Dependable running, straightforward servicing,little footprint

manufacturing. It is positioned in Xihu (West Lake) Dis. CZPT CZPT Park, 50 kilometers to the east of ZheJiang provincial
cash— HangZhou. Our firm also has practical traffic transportation, as it is 15 kilometers away from
Diaozhen City station of HangZhou-HangZhou expressway, and 30 kilometers away from CZPT HangZhou station of
ZheJiang -ZheJiang expressway.The leading item of our firm is ESR -sort Roots Blower. The roots
vacuum pump is a new type of substantial-efficiency roots blower, which is developed independently based on the
domestic and international innovative technologies. Several patented technologies have been adopted on Roots
Blower, and thus we have produced substantial results in energy conservation and noise reduction, and so on.. So considerably, our
business has invested much more than thirty,000,000 RMB to introduce this sort of superior skilled equipment as
horizontal machining center, vertical machining center, two-way CNC surface planer, CNC lathe, CNC milling
device, CNC planer, plane grinder, cylindrical grinding device, and 3 coordinates testing machine.
Apart from, we have taken various actions to CZPTize the process movement these kinds of as operating and cooperating

absorb and improve the domestic superior production technologies, so as to promote the upgrading and
optimization of the item and make the solution quality reach the superior stage at home and abroad.
ESR -type Roots Blower contains many sequence these kinds of as Three-leaves Type, Two-leaves Type and Centrifugal
Variety,which can be more divided to hundreds of kinds. The goods are extensively used in sewage treatment method,
pneumatic conveying,vacuum packaging, aquaculture, foodstuff processing, electrical energy, petrochemical, cement,
mining and other industries. Our items have such rewards as low sound, energy conserving, stable high quality,
and prolonged service existence, and many others.. With the sales outlets throughout the domestic capital cities, our items sell properly all
more than the region, and have been exported to North CZPTica,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other countries. Getting acquired the ISO9001 CZPT CZPT Method Certification, we have
recognized and enhanced the quality assurance of the products creating, production, and set up.
From the approach of layout, research and growth to the finished goods, we have obtained the whole
process controlled independently, hence providing the full foundation and reliability assure for the merchandise security
and longevity. Obtaining a perfect product sales community and after-sales support, we give our buyers with increased-
top quality and much more productive support.All staff of our organization sincerely welcome the wide masses of friends to

The Software of the Roots Blower

Routine maintenance and inspection
(one) Check all fasteners and locating pins problems regardless of whether they are loosening.
(2) Usually check no matter whether the leakage phenomenon of the human body.
(three) Spend interest to lubrication, sum of grease and noises when running,
establish whether or not it functions below the required circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop level ≥
190ºC). Change the lubricant and grease after first 200 hrs managing, and replace
once again right after a moth working. Later, exchange the lubricant and grease in accordance to the
environment and lubricant (grease) quality propose a suited alternative for 3
months.
(5) Constantly check out the inlet air filter, thoroughly clean or substitute the filter in time.
(6) Blower overload often not quickly shown, so pay interest to
the consumption and exhaust strain, bearing temperature and the current increase traits
of motor to figure out regardless of whether the blower performs normally
(7) Ahead of disassembling the blower, the assembling relation and proportions
must be recorded or measured, make marks on factors to make sure the CZPT
needs following assembling.
(eight) When newly machine or overhaul, the oil tank must be cleaned before use
and suggest change all grease after eight hrs managing.

Frequent failure reason and troubleshooting

No Failure Achievable factors Elimination approaches
one Friction
among the
impeller
(one) Impurities on the impeller,
ensuing in the gap is also modest
(two) Equipment wear, ensuing in a
huge backlash
(3) The gear is not effectively fixed,
can not sustain the impeller
synchronization
(four) Bearing wear resulting in
clearance escalating.
(1) Remove dust and verify
whether there is damage components
(two) Modify the gear gap, change
the gears if the gear backlash is
increased than the typical thirty% to
fifty%
(3)Re-assemble the gears, hold
the taper speak to area is to seventy five%
(four)Replace the bearing
two Collision
amongst
impeller and
wall, the
impeller prime
and casing
(one) Installation hole is not correct
(two) running pressure is as well
substantial, exceeding the specified
value
(three) Operating temperature is too large
(four) Casing or foundation deformation,
positioning enthusiast failure
(five) Bearing axial location is not good
(one) Change the hole
(two) Recognize causes of
overloading, diminished the strain
to the specified value
(3) Verify the installation
accuracy and decrease the pipe
tension
(four) Examine and restore bearings,
and to ensure the clearance
(5)Relocation
three Temperature
too large
(one) Oil in tank is as well considerably, way too
thick or too soiled
(two) CZPT or silencer is blocked
(three)The force is higher than
the specified value
(four)Excessive dress in of the
impeller, huge hole
(five)Poor ventilation, indoor
temperature is large, ensuing in
inlet air’s large temperature
(6) The rotating pace is also minimal,end result in the belt slipping.
(1)Reduce the oil stage or rely on
oil
(two)Remove of blocking objects
(three)Lowering the force through
the blower
(4)Repair its clearance
(five)Open vents to reduce space
temperature
(six) Boost velocity to prevent the
belt slipping.

the wheel and modify gap
(five)Check out the filter and back again
strain, increase the gap
in between the impeller inlet and the
casing
(6)Clean the impeller and the
casing, to ensure that the impeller
clearance operate
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(1)Compared with the required
stress, the strain difference
is huge that the back force or
the inlet stress is large
(two) When compared with the
products specifications, blower
circulation is also huge, so its force
increases
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (trapped)
rotating components
(5) The oil stage is as well large
(6) Narrow V-belt is overheat,
vibration is too massive, or pulley
is way too tiny
(one) Reduce the stress to the
specified price
(two) Exhaust the extra gas into
the ambiance or lessen the
blower pace
(three) Get rid of the obstructions
(4)Immediately shut down, examine
