Description
Technical field
The utility model belongs to high viscosity rotor pump technical field, and in particular to a kind of without abrasion high viscosity impeller pump.
Background technology
It is domestic at present to be used for when transfer of highly viscous material (such as grease, pitch, crude oil, epoxy resin etc.), using comparing
Extensive pump has lobe pump, screw pump and internally meshed rotor pump.Wherein internally meshed rotor pump is to introduce U.S.'s prestige to agree technology and set
A kind of novel positive displacement pump of meter.It is cost-effective since this pump configuration is reasonable, it is widely used in oil, chemical industry, building materials, food
Conduct industry.
The high viscosity internally meshed rotor pump generally used on domestic market is a power intake, i.e. motor drives
Main shaft rotates, and is engaged with the rotor generation on driven axle by the rotor installed on main shaft, to complete the conveying of liquid medium.
When containing impurity or grit in medium, bearing portion and rotor site of engagement are subject to the most heavy position of load, hold very much
It is easy to wear, seriously affect the service life of unit.
Utility model content
The purpose of this utility model is to provide a kind of without abrasion high viscosity impeller pump, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides the following technical solutions：It is a kind of without abrasion high viscosity impeller pump, including
Fixed seat, decelerating motor, variable-frequency motor and pump head, the pump head is fixedly mounted on by bottom bolts in fixed seat, described
Decelerating motor and variable-frequency motor are installed in fixed seat at left and right sides of pump head respectively, the pump head is internally provided with outer turn
Son and internal rotor, the outer rotor and internal rotor engagement, second driving shaft being fixedly connected with internal rotor one end stretch out pump
Body, and connect with variable-frequency motor by second shaft coupling, first driving shaft being fixedly connected with outer rotor one end stretches out pump
Body, and connect with decelerating motor by first shaft coupling.
Preferably, it is both provided with independent bearing lubrication system on the first driving shaft and the second driving shaft outside the pump head
System and transmission system.
The technique effect and advantage of the utility model：One power intake is changed to by this without abrasion high viscosity impeller pump
Two independent power intakes, two input shafts are rotated according to precalculated rotating speed respectively so that two independences
The rotor of rotation does contactless gear motion, bearing portion and site of engagement are not according to the equidirectional rotation of accurate rotating speed
Power rotor is born again and is transmitted through the engagement component come, is reduced mechanical wear, can be greatly improved the service life of product；Two
Independent input shaft has bearing lubrication system, reduces mechanical wear, and original horizontally-mounted decelerating motor makes vertical axis into
Installation form reduces installation space, and, without abrasion high viscosity impeller pump, mechanical wear is relatively low, and service life greatly increases, can for this
It is used with popularity.
Description of the drawings

The utility model provides as shown in Figs. 1-2 a kind of without abrasion high viscosity impeller pump, including fixed seat 7, slows down
Motor 6, variable-frequency motor 10 and pump head 4, the pump head 4 are fixedly mounted on by bottom bolts in fixed seat 7, in the pump head 4
Decelerating motor 6 and variable-frequency motor 10 are installed in the fixed seat 7 of the left and right sides respectively, the pump housing 4 is internally provided with outer
Rotor 2 and internal rotor 3, the outer rotor 2 and internal rotor 3 engage, the second driving shaft 1 that 3 one end of the internal rotor is fixedly connected
Pump head 4 is stretched out, and is connect with variable-frequency motor 10 by second shaft coupling 9, the first active that 2 one end of the outer rotor is fixedly connected
Axis 5 stretches out pump head 4, and is connect with decelerating motor 6 by first shaft coupling 8.
Specifically, being both provided with independent bearing profit on the first driving shaft 1 and the second driving shaft 5 outside the pump head 4
Sliding system and transmission system, reduce mechanical wear.
Specifically, this is without abrasion high viscosity impeller pump, the rotation of inner and outer rotors is respectively by two relatively independent driving shafts
Rotation is driven, and is rotated according to certain rotating ratio, inner and outer rotors intermeshing does not contact again, both ensure that the normal of pump
Work functions, and reduce the abrasion between moving component, because saving a big chunk energy without friction between part
Amount, also improves the working efficiency of pump, because the part processing of new construction is all the structure that universal machine tools can be completed, is also not required to
