For above-mentioned problem, prior art proposes a kind of Double side gear-reduction unit of reciprocating type water flood pump, the stable drive of the transmission co-occurrence gear drive of this device, and noise is lower, and crankcase temperature is normal, extends the working life of water injection pump.The part but this technology still comes with some shortcomings, be mainly manifested in, because the rotating speed of transmission shaft is higher, be arranged in the driving gear of motor far-end at rotation process, there will be larger vibrations, such vibrations are comparatively large to the infringement of the driving cog of gear, need to change driving gear or driven gear frequently, improve the cost of use.And dismounting is repeatedly to being sealed with adverse influence.
Meanwhile, in this class formation, reciprocating pump promotes crosshead by bent axle to do straight reciprocating motion, drives piston to promote the liquid entered in pump.Be connecting rod between bent axle and crosshead, bent axle provides power by promoting connecting rod for crosshead.The reciprocating pump now used is general all for high pressure field, the pressure that reciprocating pump can provide to device is higher, but the dangerous generation sometimes of such situation, because when device breaks down, reciprocating pump still can provide the liquid of high pressure to device, bring danger to device.
Model utility content
The utility model proposes improvement opportunity scheme to the Double side gear-reduction unit of reciprocating type water flood pump of existing use, and by the technical program, the vibrations of the effective transmission shaft reduced, decrease the infringement to geared teeth.
Another object of the present utility model it is possible to realize when overpressure in device, by the change of bar linkage structure, reduces the pressure supply of reciprocating pump, reduction production risk.
The utility model is achieved through the following technical solutions:
