Abstract
Disclosed is a multi-head three-phase mixed transporting pump with single screw which belongs to the volumetric mixed transporting pumps of the technical aspect of the mechanical engineering for the three-phase mixed transporting of solid, liquid and gas. The multi-head three-phase mixed transporting pump with single screw not only can solve the three-phase mixed transporting of transport medium, but also can effectively reduce the vibration of a unit, and automatically adjust the process. The multi-head three-phase mixed transporting pump with single screw consists of a stator with multi-head screw pump, a hollow rotor, a change valve, a cardan shaft, a drive shaft assembly and a motor. A speed reducer (9) is connected to the drive shaft assembly (7) by an oldham coupling (8); the drive shaft assembly (7) is connected to the hollow rotor (3) to drive the stator (2)with multi-head screw pump fixed on a bottom seat (11)to drive; an input connector (6) is communicated with an output connector (1) by pressing raising; a balanced mechanical seal component (10)is provided inside the drive shaft assembly (7); the automatic change valve (4)is provided on the hollow rotor (3)and the sealed type hollow cardan shaft (5). The main advantage of the multi-head three-phase mixed transporting pump with single screw is to solve the problem of three-phase mixed transporting of the transport medium, and with small vibration, favorable sealing property and high performance and quality, the multi-head three-phase mixed transporting pump with single screw can automatically adjust the process.
Description
One, technical field
The solid, liquid, gas three-phase that is used for that the utility model belongs to the mechanical engineering technology aspect mixes the mixed defeated pump of defeated positive displacement.
Two, background technique
At present, the on-the-spot screw pump that uses is made up of liquid entering hole, liquid outlet, solid single-head screw pump, cardan shaft transmission speed reducer structure.There is following problem in the use, one, for improving the fed sheet of a media discharge capacity, under equal rotating speed, must realize by strengthening single head solid rotor diameter or off-centre, cause moment of torsion and vibrations to increase; Two, the universal transmission mechanism lifting surface area is less, has seismism in the rotation process, causes universal transmission part and unit durability low, the phenomenon that rate of fault is high; Three, unit is by electric drive, and when on-the-spot accident had a power failure, unit can't make unit become a valve of closing in whole flow process to carrying flow process adjust automatically, causes the damage of other parts; Also have, the input end sealing effect is poor, is prone to the seepage phenomenon.
Three, summary of the invention
The purpose of this utility model provides the single screw rod three-phase of bull and mixes defeated pump.It is mixed defeated that this pump can not only solve the three-phase of realizing fed sheet of a media, and can effectively reduce the vibrations of unit, under unexpected power-off condition, can adjust in unit internal convection journey automatically, and the input end sealing is reliable.The positive displacement that the utility model mainly is made up of multiple thread screw pump stator, sleeve rotor, selector valve, cardan shaft and driving-shaft assembly and motor etc. is mixed defeated pump, adopt multiple thread screw pump, sealed type space universal joint cross, sleeve rotor and input end mechanical sealing mechanism; Multiple thread screw is the rotor head number more than or equal to 2 screw rod, and under equal rotating speed and discharge capacity situation, the throw of eccentric of multiple thread screw can obviously reduce, and sleeve rotor reduces eccentric rotary component quality, so this pump moment of torsion and vibrations obviously reduce.The sealed type space universal joint cross that universal transmission mechanism adopts, lifting surface area is big, when increasing driving torque, possesses the shockproof characteristics of the flexibility and reliability of rotation.Sleeve rotor not only reduces the screw rod rotating inertia force and reduces vibrations, and design has the automatic reverse valve therein simultaneously, when accident has a power failure, can automatic reverse, and make hollow rotor become a flow process part, realization is to the protection of flow process.Power intake adopts mechanical seal, has reduced the personal factor influence when sealing is adjusted, and seals reliable and stable.
The beneficial effects of the utility model are effectively to reduce the vibrations that screw rod mixes defeated pump, reduce parts and complete machine rate of fault, increase the service life, and can adjust input end ne-leakage phenomenon under the unexpected at the scene power-off condition automatically in unit to flow process.Especially can improve the manufacturing efficiency in oil field petroleum production and the course of conveying, reduce production costs.
Four, description of drawings
As figure is structural principle schematic representation of the present utility model.
Among the figure 1, out splice going splice, 2, the multiple thread screw pump stator, 3, sleeve rotor, 4, automatic diverter valve, 5, sealed type space crossed universal shaft, 6, input adapter, 7, driving-shaft assembly, 8, oldham coupling, 9, reducing motor, 10, the mechanical seal parts, 11, base
Five, mode of execution
As seen from the figure, speed reducer 9 is connected with driving-shaft assembly 7 by oldham coupling 8, can guarantee the coaxial requirement of unit; Driving-shaft assembly 7 is made as sealed type space crossed universal shaft form, driving-shaft assembly 7 is connected with sleeve rotor 3, drive eccentric rotary in its multiple thread screw pump stator that is fixed on base 11 2, realize that fed sheet of a media is communicated to the boost in pressure of out splice going splice 1 by input adapter 6, reaches the purpose of conveying.The mechanical seal parts 10 of balanced type are installed in the driving-shaft assembly 7, make the input end sealingly secure reliable, and automatic diverter valve 4 is installed in sleeve rotor 3 and crossed universal shaft 5 places, sealed type space.
