Description

Technical Field

[0001] The utility model relates to the technical field of plunger pumps, and particularly relates to a high-pressure reciprocating plunger pump with low energy consumption and energy saving. Background Art

[0002] A plunger pump is a common reciprocating pump that sucks and discharges liquid through the reciprocating motion of a plunger in a pump cylinder. The plunger pump is usually driven by an electric motor, and the rotary motion is converted into a reciprocating motion through a crankshaft or a hydraulic system. The plunger pump has high efficiency and pressure. Due to its high-pressure output, precise flow control, and wide applicability, the plunger pump plays an important role in many industrial fields;

[0003] When the plunger moves outward, a negative pressure is formed in the pump cylinder, the suction valve opens, and the liquid is sucked into the pump cylinder; when the plunger moves inward, the liquid in the pump cylinder is compressed, the discharge valve opens, and the liquid is pushed into the discharge pipeline;

[0004] From the above content, the operating performance of the plunger pump is known. However, when the existing plunger pump is operating, due to the lack of a corresponding blocking structure at its end, when there are impurities in the working medium, after the pump body works for a long time, the internal plunger structure will be worn, which will lead to a shortened service life of the pump body; at the same time, when the plunger component works continuously for a long time, a relatively high heat will be generated in the plunger part. The increase in temperature not only increases the loss of the equipment but also affects the external staff;

[0005] Therefore, this application proposes a high-pressure reciprocating plunger pump with low energy consumption and energy saving. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Embodiment 1

[0025] To solve the technical problems in the background art, a low-power and energy-saving high-pressure reciprocating piston pump is provided as follows:

[0026] Combined with Figures 1-4 As shown, a low-power and energy-saving high-pressure reciprocating piston pump provided by the present utility model includes a housing 1. One side of the housing 1 is fixedly installed with a connected outer sleeve 2. The inside of the outer sleeve 2 is butt-connected with an extended inner sleeve 22. A driving assembly 4 extending into the inner sleeve 22 is assembled inside the housing 1. A heat dissipation assembly 5 is fixedly installed at the bottom of the housing 1, and the heat dissipation assembly 5 is assembled and connected with the outer sleeve 2. A connected diversion pipe 3 is butt-connected at the end of the inner sleeve 22. A one-way liquid outlet valve 31 and a one-way liquid inlet valve 32 are respectively butt-connected and installed at the top and bottom of the diversion pipe 3. A connected blocking assembly 6 is butt-connected and installed at the bottom of the one-way liquid inlet valve 32;

[0027] During this period, by using the combination of the housing 1 and the inner and outer sleeves, the housing structure of the piston pump is formed. The driving assembly 4 can form a reciprocating motion effect within the housing structure, and the one-way liquid outlet valve 31 and the one-way liquid inlet valve 32 are made to perform corresponding liquid inlet and outlet operations by using the pressure difference. The blocking assembly 6 can better assist the entry of the fluid and block the impurities in the fluid by its own structure, avoiding the impurities from affecting the reciprocating motion of the piston component, ensuring that the piston component moves more smoothly, reducing the wear of the structure, and the heat dissipation assembly 5 is to add a cooling facility to the pump body. By using the pressure difference generated when the piston component performs reciprocating motion, the cooling water can be extracted and recycled, and thus repeated operations can be carried out to dissipate heat from the piston component and reduce the energy consumption of the pump body during operation.

[0028] The heat dissipation assembly 5 includes a lifting pipe 51, a discharge pipe 52, and a water tank 53. The water tank 53 is fixedly installed at the bottom of the housing 1. The lifting pipe 51 and the discharge pipe 52 are respectively butt-connected and installed inside the water tank 53, and the lifting pipe 51 and the discharge pipe 52 are respectively installed and connected with the top and bottom of the outer sleeve 2; The blocking assembly 6 includes a filter screen cover 61 and a feeding cavity 62. The port of the one-way liquid inlet valve 32 is butt-connected and installed with a connected feeding cavity 62. A filter screen cover 61 is fixedly installed inside the feeding cavity 62, and the filter screen cover 61 is correspondingly connected and communicated with the port of the one-way liquid inlet valve 32;

[0029] During this period, cooling water is loaded through the water tank 53. When the plunger component reciprocates, a pressure difference will be generated inside it. At this time, the cooling water in the water tank 53 will be pumped through the riser pipe 51 to the rear space of the plunger component. At the same time, along with the reciprocating motion, the cooling water will be introduced back into the water tank 53 through the outlet pipe 52. It should be noted that check valves are provided at the ends of the riser pipe 51 and the outlet pipe 52 for use in combination to achieve the check valve effect and ensure the circulating heat dissipation of the cooling water. During this period, when the fluid is pumped into the pump body, it will first enter the feed chamber 62, and the filter screen cover 61 in the feed chamber 62 will block and filter the impurities in the fluid to ensure the smooth movement of the plunger component.

[0030] Embodiment Two

[0031] As Figure 1 and Figure 4 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0032] In this embodiment, a support foot 11 is fixedly installed at the bottom of the housing 1, and an installation opening 111 for assembly is provided at the bottom of the support foot 11.

[0033] During this period, the entire pump body will be supported by the support foot 11 at the bottom of the housing 1, and personnel can complete the assembly and fixation of the support foot 11 by matching parts with the installation opening 111.

[0034] In this embodiment, the drive assembly 4 includes a motor 41, a wheel shaft 42, a guide post 43, a cam 44, a plunger 45, and a lining sleeve 46. A motor 41 is fixedly installed at the top of the housing 1. The output end of the motor 41 extends into the housing 1 and is butt-connected with a wheel shaft 42. A cam 44 is sleeved on the wheel shaft 42. A guide post 43 extending into the inner sleeve body 22 is hinged to the cam 44. A lining sleeve 46 is sleeved on the inner wall of the inner sleeve body 22. The end of the guide post 43 is butt-connected with a plunger 45, and the plunger 45 is in mutual contact with the lining sleeve 46. The connection ports of the riser pipe 51 and the outlet pipe 52 with the outer sleeve body 2 are located at the rear side of the plunger 45.

[0035] During this period, when the drive motor 41 is driven, the output shaft of the motor 41 will drive the cam 44 to rotate. At this time, the cam 44 will rotate within the wheel shaft 42, and the wheel shaft 42 will reciprocally pull the guide post 43 under the drive of the cam 44, causing the guide post 43 to reciprocate the plunger 45 within the lining sleeve 46 to achieve the required operation;

[0036] During this period, when the plunger 45 moves repeatedly, the cooling water at the rear side of the plunger 45 will flow in and out for heat dissipation along with the movement.

[0037] Embodiment Three

[0038] As Figures 1-4 shown, based on the above embodiments, the following content is further provided in this embodiment:

[0039] In this embodiment, the heat dissipation component 5 further includes a water injection port 54 and a drain port 55. The water injection port 54 is fixedly installed at the top of one side of the water tank 53, and the drain port 55 communicated therewith is fixedly installed at the bottom of the water tank 53.

[0040] During this period, personnel can add or replace the cooling water in the water tank 53 through the water injection port 54 and the drain port 55, so as to ensure the operation effect of the cooling water and avoid impurities brought out from the pump body in the cooling water.

[0041] In this embodiment, a docking socket 21 is sleeved on the inner wall of the outer sleeve 2, and the outer sleeve 2 is sleeved and connected to the inner sleeve 22 through the docking socket 21.

[0042] The docking socket 21 realizes the mutual docking and installation between the inner sleeve 22 and the outer sleeve 2. During maintenance, personnel can complete the installation and separation between the inner sleeve 22 and the outer sleeve 2 by disassembling the docking socket 21.

[0043] In this embodiment, the blocking component 6 further includes a waste discharge port 63 and a feed port 64. The waste discharge port 63 communicated therewith is fixedly installed at the bottom of the feed chamber 62, and the feed port 64 communicated therewith is docked and installed on the front surface of the feed chamber 62.

[0044] During this period, the feeding pipeline is docked and installed with the feed port 64 to realize the operation process of the pump body. And after continuous operation, there will be more impurities in the feed cavity 62. When the pump body is in a non-operating state, the discharge operation can be carried out, and the method is to complete it through the waste discharge port 63. The waste discharge port 63 is in a closed state during operation.
