Abstract
The utility model relates to a large-power five-plunger high pressure reciprocation pump which comprises a speed reduction box, a transmission gear, a crankshaft box, a crankshaft, a connection rod, a cross head and a middle rod. The crankshaft in the crankshaft is driven to rotate by the transmission gear in the speed reduction box then to drive the connection rod radially arranged on a crank throw of the crankshaft to reciprocate, the connection rod is radially hinged with the crank throw of the crankshaft through a connection rod cover and a connection rod tile, the other end of the connection rod is hinged with the middle rod through a pin shaft and the cross head, the transmission gear in the speed reduction box is meshed in a driving gear, and the driving gear is directly installed with a driving motor through an input shaft. The reciprocation pump is simple in structure, small in size, light in weight, high in efficiency, capable of substituting an existing automatic speed changer transmitted by a heavy belt or manufactured with high cost, large in transmission torque, stable in working, low in noise and suitable for different-flow and different-pressure serial high pressure plunger pumps.
Description
Technical field
The utility model belongs to pump class field, relates to high pressure reciprocating pump, especially a kind of high-power five plunger high pressure reciprocating pumps.
Background technique
At present, the transmission of high-power (400-500KW) high pressure reciprocating pump has dual mode, and a kind of is to adopt the direct drive mode of motor driving belt pulley, and another kind is the kind of drive of motor driving retarder.The shortcoming of these two kinds of kinds of drive is: 1, volume is comparatively huge, and efficient is lower, and weight is heavier, and occupation area is more; 2, for the bent axle in five plunger high pressure reciprocating pumps, in running, flexural strength is relatively poor, the high pressure reciprocating pump operation troubles easily occurs.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of simple in structure, volume is little, lightweight, efficient is high high-power five plunger high pressure reciprocating pumps are provided.
The technical solution adopted in the utility model is:
a kind of high-power five plunger high pressure reciprocating pumps, comprise speed reducer, driving gear, crankcase, bent axle, connecting rod, crosshead, intermediate bar, bent axle in driving gear driving crank case in speed reducer rotates, thereby the connecting rod of radially installing with the crank throw of dynamic crankshaft moves reciprocatingly, this connecting rod radially cuts with scissors dress by the crank throw of connecting rod cap and connecting rod bearing shell and bent axle, the other end of connecting rod adopts crosshead and intermediate bar hinge dress by bearing pin, it is characterized in that: driving gear engagement one driving gear in described speed reducer, this driving gear is direct and drive motor installation by input shaft.
And, the coaxial engine crankshaft bush that is fixedly mounted with in the radially installation one bent axle FE Tiler of the crankweb on described bent axle, this bent axle FE Tiler.
The utility model advantage and good effect are:
1, this reciprocating pump structure is simple, and volume is little, and is lightweight, and efficient is high, replaced the automotive transmission of heavy belt transmission of past or preparation price, and transmitting torque is large, stable working, and noise is low, can be suitable for different flow, different pressures series high voltage plunger pump.
2, this reciprocating pump can according to multiple different speed ratio preparation gears, be realized at a high speed and the low speed number of strokes. can satisfy multiple different flow, multiple different pressures series plunger pump.
3, this reciprocating pump has been equipped with engine crankshaft bush and bent axle FE Tiler on bent axle, has strengthened thus intensity and the rigidity of transmission of crankshaft, guarantees that bent axle in the amount of deflection internal strain of regulation, has improved the ride quality of reciprocating pump.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view;
Fig. 3 is the utility model crosshead and the enlarged diagram that is connected of intermediate bar;
Fig. 4 is the utility model bar linkage structure enlarged diagram.
Embodiment:
The utility model is described in further detail in conjunction with specific embodiments below by accompanying drawing, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of high-power five plunger high pressure reciprocating pumps, comprise speed reducer 1, driving gear 4, crankcase 3, bent axle 5, connecting rod 9, crosshead 11, intermediate bar 12, bent axle in driving gear driving crank case in speed reducer rotates, thereby moves reciprocatingly with the connecting rod of radially installing on dynamic crankshaft; Connecting rod radially cuts with scissors dress by the crank throw of connecting rod cap 8 and connecting rod bearing shell 14 and bent axle, the connecting rod the other end adopts crosshead and intermediate bar hinge dress by bearing pin 10, intermediate bar is completed high-pressure service pump suction, discharge opeing working condition requirement in the plunger work done (not shown in FIG.) that stuffing box contains.
Innovative point of the present utility model is:
1, the engagement of the driving gear in described speed reducer one driving gear 13, this gear be direct and drive motor installation by input shaft 2.
2, the coaxial engine crankshaft bush (there is no label in figure) that is fixedly mounted with in the radially installation one bent axle FE Tiler 6 of the crankweb 7 of described bent axle, this bent axle FE Tiler.The mode of structure that the crankweb of this bent axle is radially installed FE Tiler and bearing shell is same as connecting rod cap and the connecting rod bearing shell of connecting rod.
Working principle of the present utility model is:
Motor or diesel engine directly drive the high gear input shaft in speed reducer, and moment of torsion is passed to and the driving gear that is meshed, and make it bent axle and rotate, and obtain simultaneously corresponding pump speed.Bent axle drives crosshead by connecting rod assembly and makes up the conversion linear reciprocating motion that will rotatablely move, and by the plunger work done that stuffing box in the moving fluid end of crosshead assemblage zone contains, completes high-pressure service pump suction, discharge opeing working condition requirement.
Other parts that the utility model is not described in detail are prior art.
