Abstract
The utility model discloses a single-screw pump with a swinging stator. The single-screw pump with the swinging stator comprises a pump body, a swinging stator, a rotor and a motor, wherein the pump body is connected with the motor by a connecting rack; the inner cavities of the pump body and the connecting rack are provided with the swinging stator and the rotor; the rotor is directly installed and connected to the power shaft of the motor; a rotor junction body is sheathed with a skeleton oil seal; the skeleton oil seal is embedded into an oil seal ring slot on a connecting rack throat mouth part; the swinging stator comprises a cylindrical stator body and a circumstantial conical drum type outer sheath, wherein the outer sheath causes the stator body to move along with the rotor so as to swing around a self shaft; the bottom end surface of the conical drum body of the outer sheath is provided with an external extending edge clamped between the pump body and the connecting rack; and the joint of the rotor is provided with a sleeve coupling which is directly sheathed on the power shaft of the motor and is positioned by a hinge pin. The single-screw pump with the swinging stator has a simple structure, is suitable for industries, such as petroleum, chemical industry, light industry and the like to convey liquid with viscosity, multi-phase media of gas, liquid, solid and the like.
Description
Technical field
The utility model relates to a kind of improved FLUID TRANSPORTATION pump.
Background technique
Helical rotor pump is the eccentric rotating displacement pump of a kind of interior engagement.In known technology, existing helical rotor pump mainly is the jack shaft that universal joint is housed by two ends of installing in the suction body of pump, one end universal joint of jack shaft is connected with motor shaft, the other end universal joint is connected with rotor, rotor be that single head helical rotor cooperates, cover is ined succession one with the outer dress metal shell of elastic material manufacturing and have the stator of having a double meaning spiral, rotor is done the planet gyration motion in stator cavity, form the delivery volume of medium.But limit by its structure, its structure is complicated, the cost height, and the volume of pump is longer, and installing space is restricted, and also brings inconvenience to use.
The model utility content
In order to overcome the deficiencies in the prior art, it is complicated to solve existing helical rotor pump structure, awkward problem, the purpose of this utility model provide a kind of helical rotor pump of simple and practical, cost is low, the volume of pump is short, running noise is little, easy to install and use oscillating-type stator.
Addressing the above problem the technological scheme that is adopted is:
A kind of helical rotor pump of oscillating-type stator, it comprises the pump housing, the oscillating-type stator, rotor, motor, wherein, the pump housing connects motor by hitch, load oscillating-type stator and rotor in the inner chamber of the pump housing and hitch, rotor directly is installed on the line shaft of motor and is set with outside framework oil seal on the rotor disjunctor, outside framework oil seal is embedded in the oil sealing annular groove of hitch aditus laryngis portion, the oscillating-type stator makes stator body be formed around the circular cone cartridge type oversheath of swinging from axle with rotor motion by conjuncted being shaped on of cylinder shape stator main body periphery, and the bottom end of oscillating-type stator oversheath conic tube is shaped on extension limit folder and is connected between the pump housing and the hitch.
The helical rotor pump of above-mentioned oscillating-type stator, the tip side of described rotor are shaped on sleeve coupling and directly are sleeved on the line shaft of motor and by bearing pin and connect the location.
The helical rotor pump of above-mentioned oscillating-type stator, described oscillating-type stator are all made by elastic material rubber or rubber and plastic and other suitable elastic material.
When the utility model uses, be attached to desired location, connect power supply and conveyance conduit, actuating motor drives rotor and rotatablely moves, spiral part cooperates with the stator die cavity, oversheath on the oscillating-type stator cylindrical body make stator along with the motion of rotor around from axle swing, form the delivery volume of medium, medium is entered by suction port suck body cavity and be transported to the discharge body cavity, through out splice going splice output, carry out the conveying of medium.
Because technique scheme has been adopted in the utility model design, it is complicated to have solved existing helical rotor pump structure effectively, awkward problem.The overtesting result on trial shows, it compared with prior art, have simple and practical, cost is low, beneficial effects such as the volume of pump is short, running noise is little, easy to install and use, be applicable to the liquid that industries such as oil, chemical industry, light industry, sewage treatment are carried viscosity, carry the liquid that contains solid particle, fiber, suspended matter, and bull ladle contain gaseous state, liquid state or solid-state multiphase medium.
