The working theory of the a few-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By means of the motion of a pair of
synchronous gears, the two rotors rotate in reverse directions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gas in the chamber is pushed to obtain the
purpose of blowing.
Characteristic of our roots blower:
1. Massive adjustment of the air quantity
2. Lower Sounds
three. Large effectiveness
4. Minimal power cosumption
5. Long time life
6. Reliable working, simple upkeep,tiny footprint

Kind,which can be more divided to hundreds of versions. The items are broadly used in sewage therapy,
pneumatic conveying,vacuum packaging, aquaculture, food processing, electric powered electricity, petrochemical, cement,
mining and other industries. Our products have this kind of benefits as reduced sound, strength conserving, secure quality,
and long support life, etc.. With the income outlets throughout the domestic funds cities, our products offer effectively all
more than the country, and have been exported to North CZPTica,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other nations. Possessing got the ISO9001 CZPT CZPT Technique Certification, we have
recognized and enhanced the top quality assurance of the items planning, producing, and set up.
From the process of layout, study and growth to the completed items, we have received the whole
procedure managed independently, as a result providing the total foundation and dependability guarantee for the goods stability
and toughness. Getting a perfect revenue community and right after-income support, we supply our buyers with larger-
quality and far more productive provider.All personnel of our company sincerely welcome the wide masses of close friends to

Servicing and inspection
(one) Check all fasteners and locating pins conditions no matter whether they are loosening.
(two) Usually check out whether or not the leakage phenomenon of the human body.
(three) Pay consideration to lubrication, quantity of grease and noises when working,
figure out whether it performs below the needed conditions.
(four) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall stage ≥
190ºC). Exchange the lubricant and grease following very first 200 hrs operating, and replace
again following a moth operating. Later, replace the lubricant and grease in accordance to the
setting and lubricant (grease) good quality suggest a ideal replacement for 3
months.
(five) Always examine the inlet air filter, cleanse or change the filter in time.
(6) Blower overload often not instantly exhibited, so pay out focus to
the ingestion and exhaust pressure, bearing temperature and the existing boost traits
of motor to figure out whether or not the blower functions generally
(7) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on parts to make certain the CZPT
requirements after assembling.
(8) When newly device or overhaul, the oil tank ought to be cleaned before use
and propose change all grease soon after eight hrs operating.
Typical failure explanation and troubleshooting
No | Failure | Achievable causes | Elimination methods |
1 | Friction in between the impeller |
(one) Impurities on the impeller, ensuing in the gap is way too tiny (2) Equipment put on, ensuing in a large backlash (three) The equipment is not properly set, can not maintain the impeller synchronization (four) Bearing dress in ensuing in clearance increasing. |
(1) Get rid of dirt and verify whether or not there is hurt parts (2) Alter the equipment gap, substitute the gears if the gear backlash is increased than the typical 30% to fifty% (3)Re-assemble the gears, hold the taper contact spot is to 75% (four)Substitute the bearing |
two | Collision amongst impeller and wall, the impeller top and casing |
(one) Installation hole is not right (two) working pressure is as well higher, exceeding the specified value (three) Functioning temperature is as well higher (four) Casing or base deformation, positioning enthusiast failure (five) Bearing axial location is not excellent |
(one) Modify the gap (two) Determine triggers of overloading, lowered the pressure to the specified price (3) Examine the installation accuracy and reduce the pipe pressure (4) Verify and restore bearings, and to make sure the clearance (five)Relocation |
3 | Temperature also high |
(1) Oil in tank is way too a lot, also thick or too dirty (two) CZPT or silencer is blocked (three)The force is larger than the specified worth (four)Excessive put on of the impeller, huge hole (5)Very poor ventilation, indoor temperature is higher, ensuing in inlet air’s large temperature (6) The rotating velocity is as well reduced,outcome in the belt slipping. |
(1)Minimize the oil degree or count on oil (2)Get rid of of blocking objects (3)Lowering the strain via the blower (4)Mend its clearance (5)Open vents to lessen space temperature (six) Increase velocity to stop the belt slipping. |
four | Insufficient movement |
(one) The inlet filter is blocked (two) Impeller dress in and the gap increases too much (3) Belt slipping (four) Massive imports pressure reduction (5) CZPT ventilation leakage |
(1) Clear the filter dust and obstruction (2) Repair the hole (three)Tighten the belt and increase the number of belts (four)Alter the inlet force to the specified benefit (five) Check out and repair the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(one)Substantial tank place result in leakage from the discharge port (two) Seal wear, resulting in shaft oil spills (3) The force is greater than the specified worth |
(one)Decrease the oil amount (2)Exchange the seals (three)Clear the air vents, 2mm diameter faucet is mounted in the center chamber, open up the faucet beneath the wall |
six | Irregular vibration and sounds |
(1)Bearing clearance exceeds the specified worth or bearing use (two) The gear backlash is also big, not in a restricted set (three) The international objects and dust caused by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation triggered the collision induced by overload, (5) Friction between the impeller and the inlet housing brought on by overheating (6) Unbalance of the impeller caused by fouling or international human body (seven) CZPT bolts or other fasteners are loosened |
(one)Replace bearings or bearing seat (2)Reassemble equipment and make sure backlash (three)Cleaning blower, check the situation is destroyed (four)Examine the again pressure, examine the wheel and adjust gap (5)Check out the filter and back pressure, enhance the gap among the impeller inlet and the casing (six)Cleanse the impeller and the casing, to ensure that the impeller clearance perform (seven) Tighten the anchor bolts and leveling the base. |
seven | Motor overload |
(one)When compared with the necessary pressure, the strain distinction is large that the back again pressure or the inlet force is substantial (2) Compared with the products requirements, blower movement is too big, so its strain raises (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating components (5) The oil level is as well large (6) Slim V-belt is overheat, vibration is as well huge, or pulley is as well tiny |
(one) Reduce the pressure to the specified worth (2) Exhaust the excess fuel into the atmosphere or reduce the blower pace (three) Get rid of the obstructions (4)Quickly shut down, verify the reason (five) Alter the oil to the appropriate level (6) Check the belt tension, and replaced it with large diameter pulley. |
