Entrance and feed line on housing are come round, housing and input end bearing support and output terminal bearing support form a shoe cream room, shoe cream room is communicated with all the time with filler opening, filler opening is located on the oil cylinder of rotation, in turning course all the time with synchronize the inlet port of rotation and be communicated with, oil extraction is entered in main shaft and is discharged from outlet(discharge) flange by rotor; Outlet(discharge) flange communicates with outlet line, completes continuous oil-feed and oil extraction.
Between rotor and slide plate, by many row's needle rollers are installed, realize sliding friction and change rolling friction into, alleviate the output power that motor overcomes sliding friction, and working life that can elongated component.
Eccentric rotor oil-gas mixed delivery pump of the present invention has been done very large improvement on the basis of existing technology, and its technical characterstic is:
1, main transmission axial region has carried out static balancing processing by loss of weight, has got rid of the mechanical vibration that the eccentric inertia not causing on axis because of barycenter in rotation process because of solid of rotation causes main transmission axial region; Driven axial region has carried out static balancing processing by loss of weight, the mechanical vibration that the eccentric inertia not causing because of barycenter because of solid of rotation causes driven axial region have been got rid of on axis in rotation process, in the overall operation process of pump, greatly reducing vibration, is that pump housing operation is more steady.
2, input end bearing support and output terminal bearing support all have an eccentric opening position, and processing easily realizes with one heart, can guarantee the parallel of main transmission axis and driven axis.
3, the bearings position of main transmission axis and driven axis is shortened, further reduce mechanical vibration.
4, oil outlet end is discharged from outlet(discharge) flange, and there is larger buffer space in portion within it, has reduced the pulse phenomenon of the pump housing; The intensity of axle increases greatly in addition, has reduced the rotational deformation of axle, has improved the parallelism of main transmission axis and driven axis.
Many rows needle roller that 5 rotors are installed greatly reduces force of sliding friction, and the life-span of component is improved greatly.
The characteristic of property of eccentric rotor oil-gas mixed delivery pump of the present invention is:
1, solved crude oil, rock gas, water, various sticky material and solid particle and be difficult to realize the mixed defeated and supercharging of single pipeline and carry the difficult problem with the multistage conveying of long distance, and the gas-liquid delivery problem under large gas-oil ratio operating mode.
2, this pump can be realized low temperature and carries, and does not need Oil-gas Separation, does not need pressurization system, can well site or gathering station directly carry, simplified technique, reduced cost, the energy-saving and cost-reducing oil well of can realizing is without discharge, pollution-free, by the whole centralized recoveries of emptying gas.3, this structure is a kind of displacement pump, and degree of accuracy is high, from structure, has taken into account the common performance of oil pump and air compressor, can realize the operation that digitizing positive battery metering in oil field is carried.
4, this pump has been realized synchronous continuous oil extraction, and output liquid continuous uniform, pressure stability, disturbance are little, to the liquid of receptance, the change of composition can not occur, and efficiency is high, power consumption is little.
