Abstract
The utility model belongs to the technical field of liquor pumps. Because of a liquid cylinder block (9), a plunger (6) and the sealing methods thereof, and the differences of the structural forms of liquor inlet valve groups (11), (12) and the liquor discharge valve groups (7), (10), the utility model adopts a double-action working mode, so that the ejection force to a connecting rod (2), which is generated by that the liquid is feed by high pressure, the lubricated condition at the positions of a small head tile is improved, and the service life of the small head tile of the connecting rod (2) is extended. Simultaneously, liquor is discharged in the reciprocating motion during the double-action process and the reciprocal times are decreased compared with a single-action booster pump with the same parameter of the liquor discharge, so that the friction condition of the filling seal is improved and the service lives of wearing parts are extended.
Description
The utility model belongs to the liquid pump technical field.
Present suction booster is the single-acting boosting water injection pump, and this boosting water injection pump is made up of power end and fluid end two-part.Fluid end comprises: have into, the liquid cylinder of discharge opeing valve pocket and cylindrical hydraulic pressure cavity, the feed liquor valve group and the liquid discharging valve group of installing respectively in advancing on liquid cylinder, the discharge opeing valve pocket, be fixed on the liquid cylinder and with the Stuffing box of hydraulic pressure cavity on same shaft axis of liquid cylinder, be sleeved in Stuffing box and the liquid cylinder and cylindrical plunger that an end is connected with power end; Power end comprises: the crosshead, connecting rod, the bent axle that are connected with the plunger of fluid end.Power end and fluid end are fixed on the fuselage by certain way.The pump of this structure is the single-acting boosting water injection pump, is the front-end face acting with cylindrical plunger, highly pressurised liquid is pressed in the pipeline goes.But because the intake pressure that suction booster requires is the high pressure of 10～15MPa, so plunger front-end face in the motion backhaul still is subjected to the height of the feed liquor power of bearing down on one, this top power passes to the connecting rod of doing transmission of power always.Connecting rod the time is to do oscillating motion in work, and the high power of bearing down on one causes the friction pair of connecting rod small end watt can not produce moment to throw off and enter lubricant oil, lubricating condition is worsened, generally use and just caused early stage tile kilning in 100 hours, pump continuous operation for a long time.
The purpose of this utility model is to design a kind of can the water inlet to the top power of connecting rod by the balance high pressure, and the boosting water injection pump that operation is continuous, efficient is high.
The utility model comprises power end and fluid end two-part, fluid end comprises: have into, the liquid cylinder of discharge opeing valve pocket, be contained in liquid cylinder is enterprising, the discharge opeing valve pocket is interior feed liquor valve group and liquid discharging valve group respectively, near power end be fixed on the liquid cylinder and with liquid cylinder on the Stuffing box of hydraulic pressure cavity on same shaft axis, be sleeved on the interior cylindrical plunger of Stuffing box and liquid cylinder; Power end comprises: bent axle, and the connecting rod of connection crosshead and bent axle, by the crosshead that connecting sleeve is connected with the plunger of fluid end, power end and fluid end are fixed on the fuselage in some way, make it into as a whole.Its improvements are: the liquid cylinder rear and front end of fluid end part is equipped with feed liquor valve group and liquid discharging valve group respectively, and the hydraulic pressure cavity in the liquid cylinder is two garden cylindrical inner chamber that diameter does not wait and communicates, filler cover in the suit in the major diameter hydraulic pressure cavity; The plunger that is sleeved in Stuffing box and the liquid cylinder is a cylindrical pair of diameter ladder plunger, enlarged diameter section is sleeved in the interior filler cover of liquid cylinder, and form a working cell with the one group of feed liquor valve group and the liquid discharging valve group of front end, reduced diameter section is sleeved in Stuffing box and the minor diameter hydraulic pressure cavity, forms a working cell with one group of feed liquor valve group and the liquid discharging valve group near power end in the liquid cylinder.
The utility model has adopted the double-action working method in carrying the highly pressurised liquid process.When crank-connecting rod and cross head design drove the ladder plunger and move reciprocatingly, the two ends, big footpath of plunger all can be to the liquid application of force.When plunger when crankshaft direction is made drawback movement, discharge opeing high pressure on the annulus area that forms by the difference of the large and small diameter of plunger, offset the inlet hydraulic of plunger large-diameter end, thereby make plunger be in pressure balance, the connecting rod small end watt dieback that the inlet hydraulic application of force causes when having avoided old-fashioned single-action plunger piston pump to do drawback movement has improved the lubricating condition at microcephaly watt position greatly.The double-action that plunger seesaws also can make full use of the function that inlet hydraulic has had, directly is converted to the partial function of discharge opeing, improves the operational efficiency of pump.In addition, the double-action process seesaws all has liquid to discharge, the single action booster pump of comparable same row liquid measure parameter reduces reciprocal time, thereby reduce size, the weight of pump valve and the acceleration when rising and falling, reduce the average linear velocity of plunger motion, improve the gland sealed friction condition, the life-span of each easily damaged parts is improved.The reduction of reciprocal time can also improve the operating conditions of drive part, reduces the noise and the vibration of pump power end.In sum, this model utility has reached designing requirement.
Embodiment of the present utility model provides in conjunction with the accompanying drawings.
Accompanying drawing is the sectional drawing of double-action boosting water injection pump.
