Description
Technical field
The present invention relates to a kind of displacement pump of transport flow medium, particularly a kind of efficient Oil, Water, Gas mixed medium transfer pump.It can be finished the mixing of various media and carry, and can cooperate proportioning device to realize accurately quantitatively carrying of various media again.
Background technique
According to domestic and international pertinent literature report, the displacement pump of existing transport flow medium mainly contains the reciprocating pump that plays row's suction effect by piston, plunger, as reciprocating pump, plunger pump etc.; Work the rotor pump of arranging the suction effect by rotor, as gear pump, vane pump etc., its drive form has crank, cam drive, the direct driving of steam etc.
At present, carry the displacement pump of various media accurate, good, so be widely used from absorption because of its flow.But owing to compare with its centrifugal pump with capacity, volume is big, and easily damaged partss such as component manufacturing process complexity, especially its piston ring, valve seat, valve block need often to change, so its floor space is big, cost is higher.This has not only increased its maintenance load, reduced working efficiency, and the transmission noise is bigger, move not steady, the medium bad adaptability of carrying, can not finish the mixing of Oil, Water, Gas medium and carry, plunger or rotor seal poor-performing can't cooperate proportioning device to realize accurately quantitatively carrying of various media.
The inventor had designed once at the problems referred to above had both had the reciprocating pump performance, possessed the transfer pump of rotor pump characteristic again.As: it does not adopt traditional crank driving structure " a kind of plunger pump " (notification number CN2365422Y), and cancels valve block, valve seat easily damaged parts, makes designs simplification, and volume reduces.Because of utilizing slide block to be assembled in the plunger of biasing on the stationary axle in its rotor plunger hole, under the ring gear of the rotor tip that is meshed with the transmission shaft end gear drives, along with rotor when stationary axle rotates, finish suction, row's action, reach the purpose of fed sheet of a media, so be not subjected to the restriction of medium temperature, viscosity, energy transferring oil, water and gas compound medium.But rotate around stationary axle because transmission shaft drives rotor by the ring gear that drives rotor,, influence pump efficiency so its surface friction drag is big.
In order to overcome the defective of above-mentioned plunger pump, on the basis of its structure, designed " a kind of rotor plunger pump " (notification number CN2431417Y) again, it has cancelled stationary axle and axle sleeve thereof, change the twin shaft transmission into the single shaft transmission, rotate with the slide block direct driving rotor that is fixed on the transmission shaft, or with the driving rotor rotation that is meshed with the ring gear of rotor tip of the gear on the transmission shaft.Though the loading and unloading of the transmission shaft after improving are easier, be convenient to install, safeguard that surface friction drag is still bigger.
On the architecture basics of rotor plunger pump, " a kind of efficient plunger pump " (notification number CN2428594Y) this device of designing is that slide block is fixed in the rotating shaft, driving gearshaft by the bracket supports driving rotor rotation that is meshed with the external tooth cover of rotor tip, the task of fed sheet of a media is finished in plunger continuous reciprocating action along with rotor rotation the time.Plunger pump operation after the improvement is steady relatively, and noise decreases, the resistance of further reducing friction, and pump efficiency increases.Although the processing of the rotating shaft after improving, install than being easier to, shaft end seal is relatively poor, easily leaks, and the slide block stationary platen on it brings some inconvenience also for the processing of rotating shaft, installation.
Show that through on-the-spot actual motion the usability of above-mentioned rotor plunger pump is still not really desirable, also has certain defective on the structure.Processing as the ring gear of unitary rotor end or external tooth cover, a plurality of plunger holes all acquires a certain degree of difficulty, and machining accuracy reduces, and it is bigger to drive noise, influences its performance that operates steadily; The inside and outside working surface of plunger is easy to wear, lacks seal arrangement, leaks easily, is unfavorable for the metering conveying.Driving gearshaft is cantilever support, influences the mesh transmission effect of its end tooth wheel and rotor external tooth cover, easily produces noise, also influences its running stability.
Summary of the invention
The purpose of this invention is to provide a kind of efficient profit gas mixed medium transfer pump, its structural distribution is reasonable, be convenient to processing, install, sealing is reliable, nothing is leaked, transferring oil, water and gas compound medium operate steadily, effectively increase the service life, have the advantage of pump efficiency of significantly improving and accurate measurement rate.
The object of the present invention is achieved like this: this device comprises the pump housing and its interior rotor of assembling, plunger and driven shaft thereof and live axle, before the driven shaft two ends utilize bearing and mechanical seal to be bearing in the pump housing, in the biasing axis hole of bonnet, the end tooth of the live axle wheel driving rotor that is meshed with the external tooth cover of rotor rotates around driven shaft, its technological points is: described rotor adopts split-type structural, be in the same place by left rotor and right-hand rotation sub-portfolio, on the left rotor with the perpendicular direction five equilibrium of its axis plunger hole that has been staggered, the sub end of turning right has the external tooth cover that is meshed with the drive shaft end gear, the square column that has dome that is assembled in the rotor plunger hole is provided with the close encapsulation groove beyond the Great Wall week, and live axle supports by the bearing pack and the bearing in the axis hole of protecgulum bottom at carriage two ends respectively.
The described square plunger that is assembled in the rotor plunger hole is assembled on the driven shaft by slide block, and slide block connects by key, is fixed on the driven shaft.
Described driven shaft one end is provided with the lubricant oil oil hole along axis centre.
Week has the high-strength wearable sheet with the contacted working surface of rotor plunger hole to described square column beyond the Great Wall.
Week has the high-strength wearable sheet with the contacted working surface of slide block in the described square plunger.
Described rotor periphery is provided with the axial seal bar.
Described rotor periphery is provided with the radial seal ring.
Flexible Stamping Steel Ribbon in all beyond the Great Wall close encapsulation grooves of described square column.
Because rotor of the present invention adopts split-type structural, its by about change in two and partly form, with the staggered plunger hole of the perpendicular direction five equilibrium of its axis, the sub end of turning right has the external tooth cover that is meshed with the drive shaft end gear on the left rotor, structural distribution is reasonable, is convenient to processing, installs.The square column that has dome that is assembled in the rotor plunger hole is provided with the close encapsulation groove beyond the Great Wall week, and sealing is reliable, nothing is leaked.Live axle supports by the bearing pack and the bearing in the axis hole of protecgulum bottom at carriage two ends respectively, before the driven shaft two ends utilize bearing and mechanical seal to be bearing in the pump housing, in the biasing axis hole of bonnet, the low driving vibration that causes of transmission device machining accuracy that this drive form can fundamentally be eliminated the prior art existence is big, the defective that the pipe network pulsation is big, transmission surface friction drag is little, not easy to wear, effectively reduce noise, make transferring oil, water, the operation of gas mixed medium is more steady, effectively prolong the working life of rotor and square plunger, have the advantage of the pump efficiency of significantly improving.Show that through actual detected its accurate measurement rate can improve 3-5%.
