Description

Technical Field

[0001] The utility model relates to the technical field of plunger high-pressure pumps, in particular to an energy-saving multi-plunger high-pressure pump. Background Art

[0002] The working pressure of a high-pressure plunger pump generally should be between 10 MPa and 100 MPa. It belongs to a positive-displacement pump, achieving the purpose of transporting liquid by means of the periodic change of the volume in the working chamber; the mechanical energy of the prime mover is directly converted into the pressure energy of the transported liquid by the pump; the capacity of the pump only depends on the change value of the volume in the working chamber and its change times per unit time, and is theoretically independent of the discharge pressure.

[0003] Currently, when a traditional plunger high-pressure pump is in use, first, the crank in the plunger high-pressure pump is connected to an external motor. After the connection, the motor drives the crank to rotate, thereby driving the connecting rod to reciprocate. When the connecting rod reciprocates, it will drive the piston to reciprocate in the piston cylinder. As the piston cylinder reciprocates, under the action of two one-way valves, the external liquid can be pumped in and out. After being pumped in, it is then extruded through extrusion, and thus the pressurized transportation of the liquid can be realized.

[0004] Since, when the plunger high-pressure pump is designed, the designer fixes the lubricating housing of the crank to the surface of the piston cylinder. When the piston makes a piston motion in the piston cylinder, the generated heat will be transferred to the lubricating liquid in the lubricating housing, and then, the heat is transferred to the housing through the flowing lubricating liquid, so that heat dissipation can be realized. However, when the plunger high-pressure pump works for a long time, the generated heat is relatively large. At this time, simply relying on the housing for heat dissipation will easily cause the plunger high-pressure pump to work at a high temperature, accelerating the service life of the plunger high-pressure pump. If a heat dissipation device is used for auxiliary heat dissipation, it will increase the power output of the device operation and reduce the energy conservation and environmental protection of the used device.

[0031] The lubricating liquid in the lubricating box 51 can lubricate and cool the internal driving component 52. At the same time, the heat dissipation fins 55 are used to dissipate heat from the internal lubricating liquid. When the internal driving component 52 is working, the staff can observe through the transparent box 53 whether there is oil or water inside, so as to judge whether there is leakage for later maintenance.

[0036] The valve body assembly 3 includes a water pipe 31. The top surface of the water inlet pipe 1 is fixedly connected with the water pipe 31 at equal intervals.

The liquid discharge check valve 33 has the same structure as the liquid inlet check valve 32.

[0037] Through the mutual cooperation of the liquid inlet check valve 32 and the liquid discharge check valve 33 in the valve body assembly 3, it can be ensured that the liquid can be pumped from the water inlet pipe 1 into the piston cylinder 54 and then discharged from the piston cylinder 54 into the drain pipe 4, thus realizing the pressurized transportation of the liquid.

[0038] Embodiment Three

[0039] As Figures 1-7 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0040] The cooling component 6 includes a cooling box 61. The cooling box 61 is fixedly connected to the outer surface of the piston cylinder 54. The two ends of the top surface of the cooling box 61 are respectively fixedly connected with a liquid inlet pipe 62 and a liquid discharge pipe 63. One ends of the liquid inlet pipe 62 and the liquid discharge pipe 63 are respectively communicated with the inner cavity of the drain pipe 4. A liquid flowing component 64 is installed at one end of the inner cavity of the cooling box 61. The liquid flowing component 64 includes a transmission rod 641 and a push rod 642. One end of the outer surface of the cooling box 61 is rotatably connected with the transmission rod 641. One end of the outer surface of the crankshaft 521 is rotatably connected with the transmission rod 641 through a bevel gear set. One end of the transmission rod 641 is fixedly connected with a turntable 643. One side of the turntable 643 is fixedly connected with a column rod 644.

The column rod 644 slides inside the rectangular frame 646.

[0041] The liquid in the drain pipe 4 is injected into the cooling box 61 through the liquid inlet pipe 62, thereby realizing the cooling of the piston cylinder 54. After cooling, the crank rod 521 drives the transmission rod 641 and the turntable 643 to rotate. When the turntable 643 rotates, it will drive the column rod 644 and the rectangular frame 646 to slide, so that the high-temperature liquid in the cooling box 61 is discharged into the drain pipe 4 through the liquid discharge pipe 63 for drainage. At this time, it can be realized that with one driving motor, while pumping liquid, cooling is also realized, and energy saving can be achieved.

[0042] Working principle and usage process of the utility model:

[0043] In the working state:

[0044] During use, first, connect the device to an external motor through a belt. After connection, then connect the water inlet pipe 1 and the drain pipe 4 to external water pipes respectively. After connection, start the motor. When the motor works, it will drive the crankshaft 521 to rotate. When the crankshaft 521 rotates, it will drive the connecting rod 522 to reciprocate. When the connecting rod 522 reciprocates, it will drive the piston rod 523 to slide in the piston cylinder 54. When the piston rod 523 moves, it will drive the piston 524 to move. When the piston 524 draws liquid, the inlet check valve 32 will open, while the drain check valve 33 will be in a sealed state. At this time, the liquid will enter the water pipe 31 from the water inlet pipe 2 and finally enter the piston cylinder 54. When the piston 524 discharges liquid, the inlet check valve 32 will be in a sealed state, while the drain check valve 33 will be in an open state. At this time, the liquid in the piston cylinder 54 will be squeezed into the water pipe 31 by the piston 524 and finally discharged into the drain pipe 4. When the liquid is discharged into the drain pipe 4, part of the liquid will flow from the drain pipe 4 along the liquid inlet pipe 62 into the cooling box 61 to start cooling the surface of the piston cylinder 54;

[0045] When the crankshaft 521 rotates, it will also drive the cooling fan 525 and the transmission rod 641 to rotate respectively. When the cooling fan 525 rotates, it can disperse the heat radiated from the periphery of the cooling fins 55 to avoid the problem of poor heat dissipation caused by heat accumulation around the cooling fins 55;

[0046] When the transmission rod 641 rotates, it will also drive the turntable 643 to rotate. When the turntable 643 rotates, it will drive the column rod 644 to rotate in a circle. When the column rod 644 rotates in a circle, it will slide up and down in the rectangular frame 646 and also drive the rectangular frame 646 to move left and right, causing the push rod 642 to reciprocate left and right. When the push rod 642 reciprocates, it will drive the push plate 645 to reciprocate in the cooling box 61. When the push plate 645 reciprocates, the high-temperature liquid in the cooling box 61 can be discharged into the drain pipe 4 from the drain pipe 63, achieving heat exchange and at the same time realizing energy saving.
