Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure plunger pumps, in particular to a bearing reinforcement structure of a high-pressure plunger pump. Background Art

[0002] High-pressure plunger pump is a mechanical device used to transport high-pressure liquids. It is usually used in industrial fields where high-pressure liquid transportation is required, such as water pumping stations, petroleum industry, chemical industry, etc. Its working principle is to suck in and discharge liquids through the reciprocating motion of the plunger in the cylinder, thereby achieving liquid transportation. Because it can provide high-pressure liquid transportation, it plays an important role in some specific industrial applications.

[0003] The current high-pressure plunger pumps work under high pressure for a long time. The high-speed rotation and the impact of high-pressure liquid will cause a large amount of heat to accumulate in the bearings. This heat cannot be effectively dissipated, causing the bearing temperature to gradually increase. As the temperature rises, the material properties of the bearings may change, such as reduced hardness and weakened strength, and may even cause permanent deformation of the bearings, affecting their performance and life. Utility Model Content

[0004] The utility model aims to provide a high-pressure plunger pump bearing reinforcement structure with cooling effect.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A high-pressure plunger pump bearing reinforcement structure includes a pump body, a bearing seat is installed at the end of the pump body, a bearing is arranged inside the bearing seat, the bearing is sleeved on the main shaft of the pump body, and a sealing shell is installed on the outer surface of the bearing. A sealing cover is installed on the outer surface of the pump body, a water pump is arranged inside the sealing cover, a water outlet pipe is connected to the outer surface of the sealing cover, and one end of the water outlet pipe is connected to the output end of the water pump, and the other end of the water outlet pipe passes through the inside of the bearing seat and is connected to the sealing shell. A first return water pipe is connected to the outer surface of the other side of the sealing shell, the end of the first return water pipe passes through the outside of the bearing seat and is connected to a first spiral tube, the outer surface of the sealing cover is connected to a second return water pipe, the end of the second return water pipe is connected to a second spiral tube, and the first spiral tube and the second spiral tube are connected by a connecting tube.

[0007] It can be seen that the water inside the sealing cover is pumped into the sealing shell through the water pump, and then flows back to the sealing shell to achieve circulation. When the water flows inside the sealing shell, the heat generated by the bearing can be taken away, thereby achieving the purpose of continuous cooling, ensuring the normal use of the bearing, and improving its performance and life. In addition, through the arrangement of the first spiral tube and the second spiral tube, the flow time of water in the external environment can be increased, which plays a cooling role, thereby ensuring its cooling effect on the bearing.

[0008] Furthermore, a support rod is installed on the outer surface of the pump body, a mounting tube is installed on the end of the support rod, a cooling fan is arranged inside the mounting tube, and the cooling fan is on the same plane as the first spiral tube and the second spiral tube.

[0009] By starting the cooling fan, the wind generated by the fan blows toward the second spiral tube and the first spiral tube, thereby improving the cooling effect of the water, causing the water to drop to a lower temperature quickly, thereby ensuring the cooling effect on the bearing.

[0010] Furthermore, a dustproof net is provided at one end of the installation tube facing away from the first spiral tube, and the dustproof net is made of stainless steel.

[0011] The dustproof net can intercept dust in the air and prevent dust from entering the installation pipe and adhering to the cooling fan, thereby affecting the performance and life of the cooling fan.

[0012] Furthermore, heat dissipation fins are evenly installed on the side surface of the sealing cover.

[0013] By providing the heat dissipation fins, the cooling effect of the water inside the sealing cover can be further improved, thereby ensuring the cooling effect of the water on the bearing.

[0014] Furthermore, the outer surface of the connecting pipe is connected to a water injection pipe, the outer surface of the water outlet pipe is connected to a drainage pipe, and sealing caps are provided at the ends of the water injection pipe and the drainage pipe.

[0015] After a period of use, you can open the sealing cap at the end of the drain pipe to drain the water inside the sealing cover, then open the sealing cap at the end of the water injection pipe, and inject clean water into the sealing cover through the water injection pipe to complete the water replacement and reduce the formation of scale.

[0016] Furthermore, the heat dissipation fins are made of copper.

[0017] Copper, as an excellent thermal conductive material, has good thermal conductivity, so it can improve the cooling effect on water. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model is described in detail below with reference to the accompanying drawings.

A sealing cover 105 is installed on the outer surface of the pump body 100, a water pump is arranged inside the sealing cover 105, and a water outlet pipe 106 is connected to the outer surface of the sealing cover 105, and one end of the water outlet pipe 106 is connected to the output end of the water pump, and the other end of the water outlet pipe 106 passes through the interior of the bearing seat 101 and is connected to the sealing shell 104. The other side outer surface of the sealing shell 104 is connected to a first water return pipe 107, the end of which passes through the outside of the bearing seat 101 and is connected to a first spiral tube 108. The outer surface of the sealing cover 105 is connected to a second water return pipe 109, the end of which is connected to a second spiral tube 110. The first spiral tube 108 and the second spiral tube 110 are connected via a connecting tube 111.

[0024] When in use, first fill the sealing cover 105 with clean cooling water, then start the water pump inside the sealing cover 105 when the pump body 100 is running, and the water pump draws the water inside the sealing cover 105 into the water outlet pipe 106 and enters the inside of the sealing shell 104. After flowing through the inside of the sealing shell 104, the water takes away the heat of the bearing 102 and is discharged through the first return pipe 107. The discharged warm water passes through the first spiral tube 108 and the second spiral tube 110 in turn, which increases its flow time in the external environment, so it can play a cooling role. The cooled water then enters the sealing cover 105 through the second return pipe 109 to achieve the purpose of circulating cooling of the bearing 102.

By starting the cooling fan, the wind generated by it blows toward the second spiral tube 110 and the first spiral tube 108, thereby improving the cooling effect of the water, causing it to quickly drop to a lower temperature, thereby ensuring the cooling effect on the bearing 102.

[0026] Specifically, a dustproof net 300 is provided at one end of the mounting tube 201 facing away from the first spiral tube 108. The dustproof net 300 is made of stainless steel. The dust in the air can be intercepted by the setting of the dustproof net 300 to prevent dust from entering the mounting tube 201 and adhering to the cooling fan, thereby affecting the performance and life of the cooling fan.

[0027] Specifically, the side surface of the sealing cover 105 is evenly installed with heat dissipation fins 400 . The arrangement of the heat dissipation fins 400 can further improve the cooling effect of the water inside the sealing cover 105 , thereby ensuring the cooling effect of the water on the bearing 102 .

After a period of use, the sealing cap at the end of the drain pipe 501 can be opened to discharge the water inside the sealing cover 105, and then the sealing cap at the end of the water injection pipe 500 can be opened, and clean water can be injected into the sealing cover 105 through the water injection pipe 500, thereby completing the water replacement and reducing the generation of scale.

[0029] Specifically, the heat sink fins 400 are made of copper. Copper is an excellent thermal conductive material with good thermal conductivity, so it can improve the cooling effect on water.
