Abstract
The utility model provides a lobe pump of high dynamic balance, including a rotor, the both sides of rotor are provided with the balancing hole respectively, the balancing hole is the airtight structure of cavity. The utility model discloses a lobe pump of high dynamic balance, the balancing hole through the rotor adopts the airtight structure of cavity, reaches the lightweight purpose of design, has both reduced rotor amount of unbalance, avoids again at the rotor unbalance phenomena that rotor balancing hole surface arouses, still having been reduced the gaseous volume of backflowing because of taking out the medium adhesion, and scaling is pressed to the air suction efficiency and the zero delivery that have increased the product, simultaneously, the side cap of adoption ring flange structure increases lobe pump of high dynamic balance's the bearing or the cleanliness of gear mesh lubricating oil, reduces the damage of bearing and gear, simple structure, convenient to use, quick.
Description
Technical field
This utility model is related to a kind of mechanical manufacturing field, refers in particular to a kind of high dynamically balanced lobe pump.
Background technology
At present, lobe pump is to be run up by internal two figure of eight rotors and take away pumped gas, therefore to sieve
The requirement for dynamic balance of thatch pump rotor is very high.
Meanwhile, balance pipe two of existing roots pump rotor is all via design, and in actual use, it is special
When not being that pumped gas has dust, coercibility and toughness, can paste on the surface and balance pipe of roots pump rotor, affect sieve
The dynamic balancing of thatch pump, causes Roots's pump vibration or failure.
In addition, the cleannes requirement of the bearing of lobe pump or gear mesh lubricating oil is very high, all can if any small granule
Bearing and gear destruction are caused, the service life of bearing and gear is affected, increases the maintenance cost of pump, the reliability drop of pump operation
Low, such case also limit lobe pump use range, hinder the further genralrlization of lobe pump.
It is accordingly required in particular to a kind of high dynamically balanced lobe pump, to solve above-mentioned existing problem.
The content of the invention
To overcome the defect existing for prior art, this utility model to provide a kind of high dynamically balanced lobe pump, solve
Lobe pump in actual applications balance pipe inwall cause the dynamic balance performance of pump rotor to be deteriorated because of adhesions such as adhering dusts, pump
The failures such as vibration, rotor collision.
High dynamically balanced lobe pump of the present utility model, including a rotor, the both sides of the rotor are respectively arranged with balance
Hole, the balance pipe are hollow closed structure.
In one embodiment of the present utility model, the hollow closed structure includes the sealing for being arranged on balance pipe both sides
Block, the external diameter of the sealing block are engaged with the internal diameter of the balance pipe.
Further, the sealing block is arranged on the both sides of balance pipe by welding manner.
In one embodiment of the present utility model, the lobe pump also includes a side cover, and the side cover is tied for ring flange
Structure.
This utility model is due to use above technical scheme so as to have an advantageous effect in that：
Hollow closed structure is adopted by the balance pipe of rotor, light-weight design purpose is reached, rotor has both been reduced uneven
Weigh, avoid again, because being taken out the rotor unbalance phenomenon that medium sticking to rotor balancing hole surface and causing, also reducing gas
Regurgitation volume, increased the pumping efficiency and zero delivery compression ratio of product；Meanwhile, using the side cover of flange plate structure, increase high
The cleannes of the bearing or gear mesh lubricating oil of dynamically balanced lobe pump, reduce bearing and gear destruction, simple structure, user
Just, quickly.
The characteristics of this utility model, see the detailed description of this case schema and following preferable embodiment and obtain clear
Ground understands.
Description of the drawings
Fig. 1 is the structural representation of high dynamically balanced lobe pump of the present utility model；
Fig. 2 is the structural representation of side cover of the present utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and this utility model is expanded on further.
With reference to shown in Fig. 1 and Fig. 2, high dynamically balanced lobe pump of the present utility model, including a rotor 2, the both sides of rotor 2
Balance pipe 3 is respectively arranged with, balance pipe 3 is hollow closed structure.
In the present embodiment, the hollow closed structure includes the sealing block 31 for being arranged on 3 both sides of balance pipe, sealing block 31
External diameter be engaged with the internal diameter of balance pipe 3.Sealing block 31 is arranged on the both sides of balance pipe 3 by welding manner.
In the present embodiment, the lobe pump also includes a side cover 1, and side cover 1 is flange plate structure.
Balance pipe 3 adopts hollow closed structure, reaches light-weight design purpose, has both reduced 2 amount of unbalance of rotor, kept away again
Exempt from 2 energy imbalance of rotor caused because being taken out medium and sticking to 3 surface of balance pipe of rotor 2, also reduce returning for gas
Flow, increased pumping efficiency and zero delivery compression ratio.
Meanwhile, side cover 1 is flange plate structure, and simple structure puts, and increased bearing or gear mesh lubrication
The cleannes of oil, reduce bearing and gear destruction.
High dynamically balanced lobe pump of the present utility model, it is simple structure, easy to use, quick, it is easy to solve because being taken out Jie
2 energy imbalance of rotor that matter sticks to 3 surface of balance pipe of rotor 2 and causes, reduces out husky, clear husky difficulty, makes high dynamic
The lobe pump of balance reaches higher prescription.
Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed this utility model, this utility model
Claimed scope is by appending claims and its equivalent thereof.
