As shown in fig. 1-4, a plunger pump includes a fluid end assembly and a power end assembly, which are connected by a connecting rod (conventional connection method disclosed in the prior art). The hydraulic end assembly and the power end assembly are conventional component structures disclosed by the existing plunger pump, and a person skilled in the art can refer to a technical manual or a technical dictionary or the internal structure and the working principle of the hydraulic end assembly and the power end assembly in the plunger pump.
The hydraulic end assembly comprises a first shell 1, and working components of the hydraulic end assembly, such as a valve box, a plunger channel, a valve and the like, are positioned in the first shell 1. A first impeller 11 is rotatably connected to a center of a right side wall of the first housing 1 (the first impeller 11 is rotatably connected to the first housing 1 through a rotating shaft-bearing structure). The power end assembly comprises a second housing 2, and the working component of the power end assembly, such as an eccentric power component, is located in the second housing 2.
The center of the right side wall of the second casing 2 is rotatably connected with a second impeller 21 (the second impeller 21 is rotatably connected to the second casing 2 through a rotating shaft-bearing structure), and the first impeller 11 and the second impeller 21 are arranged to respectively dissipate heat of the fluid end assembly and the power end assembly by using the first impeller 11 and the second impeller 21.
The first impeller 11 is provided with first cooling fins, specifically, the shape of the first cooling fins is a blade shape, the first cooling fins are symmetrically distributed on the outline of the first impeller 11, and the number of the first cooling fins is 10.
The second impeller 21 is provided with second heat dissipating blades, specifically, the second heat dissipating blades are in a shape of a blade, the second heat dissipating blades are symmetrically distributed on the outline of the second impeller 21, and the number of the second heat dissipating blades is 6.
The first impeller 11 is in transmission connection with the second impeller 21 through a transmission belt, specifically, the first impeller 11 is provided with a first belt wheel 12, the second impeller 21 is provided with a second belt wheel 22, and the first belt wheel 12 is in transmission connection with the second belt wheel.
The second impeller 21 is provided with a power belt wheel 23, the power belt wheel 23 is used for connecting a main belt wheel (not shown) on the driving motor, the main belt wheel on the driving motor is in transmission connection with the power belt wheel 23 through a transmission belt, the driving motor drives the power belt wheel 23 to rotate, the second impeller 21 rotates, and the second impeller 21 drives the first impeller 11 to rotate.
The first casing 1 is provided with a heat dissipation channel 13 corresponding to the first impeller 11 (the opening direction of the heat dissipation channel 13 is perpendicular to the vertical plane where the first impeller 11 is located), and the second casing 2 is provided with a heat dissipation channel 13 corresponding to the second impeller 21 (the opening direction of the heat dissipation channel 13 is perpendicular to the vertical plane where the second impeller 21 is located).
The specific structure of the heat dissipation channel 13 is as follows: because the first housing 1 has a certain thickness (the heat dissipation channel 13 is located at the side edge of the first housing 1 and evenly distributed at the side edge of the first housing 1), the channel opening at one side of the heat dissipation channel 13 is located at the right side wall of the first housing 1, the channel opening at the other side of the heat dissipation channel 13 is located at the left side wall of the first housing 1, and the channel openings at the two sides are communicated. Similarly, the heat dissipation channel 13 of the second housing 2 is designed in the same way.
The process of radiating the plunger pump by the components is as follows:
the driving motor drives the power belt wheel 23 to rotate, the power belt wheel 23 drives the second impeller 21 to rotate, and the second impeller 21 drives the first impeller 11 to rotate. When the first impeller 11 and the second impeller 21 rotate, the wind blows toward the right side walls of the first casing 1 and the second casing 2, enters the heat dissipation channel 13 from the channel openings on the side walls, and is discharged from the channel openings on the left side walls of the first casing 1 and the second casing 2. In the process that the wind direction flows from the heat dissipation channel 13, the heat dissipation channel 13 is dissipated, and therefore, the heat of the pump body is dissipated by the airflow. Since the number of the heat dissipation channels 13 is plural, a large amount of heat can be dissipated at the same time.
The device components have the advantages that:
the first impeller 11 and the second impeller 21 with the transmission function are used for dispelling wind and dissipating heat in the heat dissipation channel 13, so that the heat dissipation efficiency is high, the heat dissipation range of the first impeller 11 and the second impeller 21 is large, the part without the heat dissipation channel 13 can be dissipated, and if the part where the plunger is located (the corresponding position of the first shell 1), large-area and high-efficiency heat dissipation is realized through the heat dissipation of the first shell 1. Similarly, the power end assembly can also dissipate heat in a large area and with high efficiency.
Plunger pump is at the actual operation in-process, like the mine operation, and operational environment is comparatively abominable, consequently, sets up protecting cover part 3 that can protect power end assembly and hydraulic end assembly on the plunger pump, protects whole plunger pump through protecting cover part 3 and avoids external destruction, if avoid acid rain to corrode (the material of arc apron 31 is toughened glass).
Specifically, the protecting cover assembly 3 includes an arc-shaped cover plate 31 matched with the plunger pump, and the arc-shaped cover plate 31 can completely cover the power end assembly and the hydraulic end assembly. The right side of plunger pump bottom is provided with the base 35 of C shape, and arc apron 31 rotates to be connected on the base 35 of C shape (the left end symmetry of arc apron 31 is provided with two fixed pin axles, and base 35 is provided with the pinhole with fixed pin axle complex, and fixed pin axle rotates to be connected in the pinhole) rotates arc apron 31, and arc apron 31 rotates round base 35 to shroud gradually on power end assembly and fluid end assembly.
