Description
Technical field
The present invention relates to screw pump, be specially the high pressure screw pump for pumping multiphase medium.
Background technique
The rock gas of occurring in nature is based on gas hydrates, and the overwhelming majority is contained in solid form in seabed, and exploitation difficulty is very large.Laboratory experiment is for exploring the exploitation of ocean gas hydrate, usually by water and rock gas at high pressure low temperature (P=10MPa, T=2 DEG C) reactor in synthesized hydrate, carry out fragmentation and form hydrate slurry body, in the test of hydrate solid state fluidizing, how heterogeneous slurry carries out pumping is a technical barrier urgently to be resolved hurrily.Foregoing shows the development along with science and technology, and the situation of multi-phase mixed delivering will replace the mode of movement of single-phase or simple mixed phase gradually, and the increasing pressure had along with fed sheet of a media is high, needs the requirement of bearing high pressure also to improve to pumping installations.Centrifugal pump can reach the object of conveying high-pressure medium, but when producing cavitation containing gas in medium, pump cannot normally be worked.Screw pump itself has the feature of pumping multiphase medium, but can not bear High Pressure Difference due to the packing seal between its import and bearing, limits the pressure of screw pump fed sheet of a media.How under existing condition, enabling pumping installations conveying high-pressure multiphase medium, meet the basic demand of the defeated experiment pumping of gas hydrates solid state fluidizing pipe, is the technical barrier of this simulation.
Summary of the invention
For above-mentioned technical problem, the object of the invention is to overcome the deficiencies in the prior art, for the defeated experiment of heterogeneous pipe provides a kind of screw pump of pumping multiphase medium under high inlet pressure.
The present invention is achieved through the following technical solutions:
For the high pressure screw pump of pumping multiphase medium, comprise discharging body, body of feedstock and compensator; Discharging body arranges media outlet; Body of feedstock is arranged medium inlet and hydraulic control mouth; Discharging body is connected with one end of body of feedstock by connecting rod, and connecting rod internal fixtion is provided with stator; The body of feedstock the other end is connected with bearing support, bearing support by support installing in compensator; Have screw axis in stator, have coupling shaft in body of feedstock, transmission shaft is arranged in bearing support by bearing; Screw axis is connected with coupling shaft by universal joint, and coupling shaft is connected with transmission shaft by the second universal joint; Transmission shaft is connected with waterproof machine by coupling; In described bearing support, filler seat is also installed, seals between filler seat and transmission shaft and be filled with filler; Bearing support end has bearing cap to seal; There is surge pipe to be connected between compensator and the hydraulic control mouth of body of feedstock, in surge pipe, have piston; Discharging body, compensator are arranged on base; Compensator there is turnover oil pipe, turnover oil pipe is provided with stop valve.
Before pump work by turnover oil pipe by Silicone oil injection in compensator, by the gap between parts make have living space and be full of silicone oil, comprise spaces all in bearing support.Silicone oil itself is nonconducting normal work that can ensure waterproof machine.Having in surge pipe can the piston of movement therein, a transmission of pressure not Transfer Medium when body of feedstock pumps into high-pressure medium.Piston under high pressure normally can work and not leak, and due to the incompressibility of silicone oil on the right side of piston, piston is only mobile in surge pipe just can make generation in compensator be equal to the high pressure of charging in-vivo medium.By this mode, surge pipe has been communicated with body of feedstock cavity and compensator makes pressure at both sides balance all the time, now High Pressure Difference would not be born between Gland and filler seat in packing seal, namely sealing failure of fillers can not be made to cause leaking, reach the object of energy pumping high-pressure medium, and also can pumping low-pressure medium.
High pressure screw pump for pumping multiphase medium provided by the invention, energy conveying high-pressure multiphase medium, solves balance packing seal High Pressure Difference leakage failure problem.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, below the accompanying drawing used required in embodiment or description of the prior art is briefly described.
Fig. 1 is general arrangement schematic diagram of the present invention.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, but be not intended to limit the present invention.Based on the embodiment in the present invention, related domain ordinary person, not making the every other embodiment obtained under creative work prerequisite, will belong to the scope of protection of the invention.
As shown in Figure 1, for the high pressure screw pump of pumping multiphase medium, comprise discharging body 1, body of feedstock 6 and compensator 19; Discharging body 1 is arranged media outlet a; Body of feedstock 6 is arranged medium inlet b and hydraulic control mouth c; Discharging body 1 is connected with one end of body of feedstock 6 by connecting rod 2, and connecting rod 2 internal fixtion is provided with stator 3; Body of feedstock 6 the other end is connected with bearing support 12, bearing support 12 by support installing in compensator 19; Have screw axis 4 in stator 3, have coupling shaft 7 in body of feedstock 6, transmission shaft 15 is arranged in bearing support 12 by bearing 13; Screw axis 4 is connected with coupling shaft 7 by universal joint 5, and coupling shaft 7 is connected with transmission shaft 15 by the second universal joint 29; Transmission shaft 15 is connected with waterproof machine 18 by coupling 17; In described bearing support 12, filler seat 9 is also installed, seals between filler seat 9 and transmission shaft 15 and be filled with filler 10; Bearing support 12 end has bearing cap 16 to seal; There is surge pipe 8 to be connected between compensator 19 and the hydraulic control mouth c of body of feedstock 6, in surge pipe 8, have piston 32; Discharging body 1, compensator 19 are arranged on base 23; Compensator 19 there is turnover oil pipe 22, turnover oil pipe 22 is provided with stop valve 21.
Before pump work by turnover oil pipe 22 by Silicone oil injection in compensator 19, make to have living space in tank to be full of silicone oil by the gap between parts.Surge pipe 8 can at the piston 32 of inside movement owing to being added with, and body of feedstock pressure is passed in compensator 19 by piston 32.Surge pipe 8 has been communicated with body of feedstock 6 cavity and compensator 19 makes pressure at both sides balance all the time, now filler 10 would not bear High Pressure Difference, namely sealing failure of fillers can not be made to cause leaking, reach the object of energy pumping high-pressure medium, and also can pumping low-pressure medium.
When specific works, the technological process of screw pump: before screw pump work, opening stop valve 21 makes silicone oil flow in compensator 19 by oil inlet and outlet f, silicone oil flows in surge pipe 8 from hydraulic control mouth d compensator 19, when being also full of silicone oil in surge pipe 8 and making piston 32 be expressed to the surge pipe leftmost side, close stop valve 21.By electric source line interface e, waterproof machine 18 power supply is connected, connect the pipeline of feeding and discharging body, open waterproof machine 18 and screw pump is started working.Close waterproof machine after having worked, when pumping system internal pressure is replied normally, open stop valve 21 and the silicone oil in compensator 19 is discharged.
