Abstract
The utility model relates to a dual-cylinder large flow electric pressure test pump, comprising a motor, a shaft coupler fly wheel, an input shaft, a variable speed transmission bearing, an eccentric main shaft, a sliding block, a cross head, a plunger piston, a water pressing cylinder, a water collector, a water tank, etc. At the connection point of the motor and the input shaft, the shaft coupler fly wheel is adopted. A blade is cast on the end surface of the fly wheel. A bearing sleeve made by the zinc alloy is adopted on one end of the input shaft. Two special type convex keys are fixed on the outer ring of the variable speed transmission bearing. In a middle pressure cylinder and a low pressure cylinder, a sealing device which is combined with the nylon rubber and an expanded graphite sealing ring is adopted.
Description
The big flow motor test pump of twin-tub, it is applicable to that the product of high-pressure bottle and mechanical device thereof or part make hydraulic pressure, oil pressure, sealing intensity and rubber tube are done the test of aspect such as blast, can make jetting machine usefulness if load onto spray gun accessories.
In existing twin-tub motor-drive pump transmission system, mostly adopt speed reducer to carry out transmission.The patent No. as our factory production is: 88212212,6 flywheel planetary gear speed-reduction twin-tub motor test pump, and by the flywheel planetary gear reducing mechanism, compositions such as the pump housing, setting-out cylinder water-collecting machine, water tank.This pump duty is little, and inefficiency can not satisfy the pressure testing of bulk container.4D-SY four cylinder motor test pumps and for example adopt worm and gear speed-reduction apparatus, make complex structure, volume is big, the pump housing is heavy, and transmission efficiency is low.
The purpose of the present utility model is: designs a kind of twin-tub motor test pump structure that is suitable for mutually with variable speed transmission bearing that adopts, the volume of pump reduced, and simple in structure, in light weight, easy to operate, move flexibly the transmission efficiency height.
The utility model is by motor, coupling flywheel, and variable speed transmission bearing, input shaft, eccentric main axis, slide block, crosshead, plunger, Sealing, setting-out cylinder, water-collecting machine, water tank etc. are partly formed.Motor adopts coupling to connect with flywheel with input shaft, end at flywheel is cast with fan blade, input shaft one end is equipped with the bearing housing made from zinc alloy material, the other end is equipped with rolling bearing, the variable speed transmission bearing outer ring is that the garden shape the other end is that tetragonal protruding key is fixed with two one ends, in, the Sealing of low pressure (LP) cylinder adopts the YXd nylon rubber seal ring and the seal arrangement that carbon seal ring combines that rises of splashing.
Its range of working pressure is 2.5~160MPa, and flow is 40~2000L/h.
The utility model compared with prior art.Have simple in structurely, volume is little, and is in light weight, easy to operate, move flexibly, transmission efficiency height, advantage such as pressure is big.
Below in conjunction with accompanying drawing embodiment is described:
The utility model is connected with the flywheel that is contained in input shaft (5) (4) by the claw type structure of three symmetries on the coupling (2) that is contained on the motor (1), coupling (2) and the middle rubber elasticity piece (3) that six claw type structures are housed of flywheel (4), be used for adjusting and the buffering effect, one end face of flywheel (4) is cast with six fan blades, when flywheel (4) rotates, fan blade can be taken away the heat that variable speed transmission bearing (9) produces, input shaft (5) is directly packed in the eccentric opening of variable speed transmission bearing (9), input shaft (5) is equipped with rolling bearing (7) and outside framework oil seal (6) near an end of flywheel (4), its the other end is equipped with the bearing housing made from the abrasion-proof zinc alloy material (8), variable speed transmission bearing (9) outer ring is a garden shape with two one ends, the other end is a tetragonal protruding key (11), (12), be fixed on the casing (38), and compress sealing with plug screw (13).By 4 output pins (10) of being adorned in 4 holes, variable speed transmission bearing (9) middle level, import the rotating speed after the speed change into output disc (14) and eccentric main axis (16), output pin (10) one ends are equipped with screw and packing ring, are used for preventing that output pin (10) from moving, and dismounting is used in the time of also can assembling.
Eccentric main axis (16) is used key connecting with output disc (14), on the eccentric main axis (16) two conical bearings (17) are housed and outside framework oil seal device (18) adjusting nut (15) is used for regulating its running clearance, outside framework oil seal device (18) is used for preventing that setting-out cylinder (26) percolating water from flowing in the variable speed transmission bearing (9).
Eccentric main axis (16) drives slide block (19), and slide block (19) moves in crosshead (20) hole, thereby drives plunger (21), (22) work.Select plunger (21), (22) of different-diameter and the setting-out cylinder (26) that is complementary with it and Sealing (23), (24), (27), (28) according to different pressure and flow, when pressure when 40MPa is above, Sealing (23) (24) adopts the long guide pin bushing of beryllium-bronze material and the seal form that high voltage bearing soft packing combines.When pressure when 40MPa is following, the YXd sealed nylon circle and the seal form that carbon seal ring combines that rises of splashing are adopted in Sealing (27), (28), have improved sealability and life-span like this.When plunger (21), (22) to-and-fro motion work, liquid passes through suction sleeve (29) from water tank (37), inlet valve (30) enters setting-out cylinder (26), pass through outlet valve (31) from setting-out cylinder (26) again, enter water-collecting machine (36), pressure maintaining valve (32) and water output connector and enter pressure testing in the pressure-vessel again, can see pressure value from the pressure gauge that is contained on the pressure gauge extension bar (33) during pressure testing, when pressure is counted above necessary requirement, liquid is discharged from safety valve (34), after pressure testing is intact, dismantle pressure release valve (35) step-down.
