Description

Technical Field

[0001] This utility model relates to the field of petrochemical process pump technology, and more specifically, to a high-temperature, high-pressure, wear-resistant petrochemical process pump. Background Technology

[0002] In the petrochemical industry, chemical process pumps, as core equipment, undertake the critical task of transporting various media. As the petrochemical industry develops towards large-scale and refined operations, the performance requirements for chemical process pumps are becoming increasingly stringent, especially under conditions of high temperature, high pressure, and highly abrasive media. The application scenarios for chemical process pumps are extremely broad, covering multiple key areas such as oil refining, petrochemical purification, petrochemical industrial engineering, coal processing, cryogenic engineering, and oil transportation engineering. In these complex production processes, pumps often need to operate under extreme conditions such as high temperature, low temperature (or ultra-low temperature), high pressure, flammable, explosive, and toxic / corrosive media. Some also need to operate under special conditions such as high inlet pressure, high head, high viscosity, low flow rate, and high cavitation. This places extremely stringent requirements on the performance of chemical pumps, particularly regarding corrosion resistance, leak tolerance (for toxic media), and wear resistance.

[0003] Existing chemical process pumps exhibit numerous problems when dealing with high-temperature, high-pressure media containing solid particles. For example, some pumps have a coating on their inner wall to withstand high temperatures, high pressures, and wear. However, when there are many solid particles, the inner wall is prone to scratches, affecting the service life of the process pump. Furthermore, chemical process pumps are large in size, making them inconvenient to move and unsuitable for flexible application scenarios. Utility Model Content

[0004] The main objective of this invention is to provide a high-temperature, high-pressure, wear-resistant petrochemical process pump that can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-temperature, high-pressure, wear-resistant petrochemical process pump includes a motor assembly and a pump head assembly, wherein the motor assembly and the pump head assembly are connected.

[0007] The pump head assembly includes a first base, a connecting pump head is fixedly installed on the top of the first base, an embedded groove is provided on the right side of the first base, and fixing blocks are fixedly installed at both ends of the right side of the first base.

[0008] The motor assembly includes a second base, a fixed motor is fixedly installed on the top of the second base, mounting slots are provided at both ends of the left side of the second base, and an insert block is fixedly installed on the left side of the second base.

[0009] Preferably, the fixing block is snapped into the inside of the mounting groove, and the second base is fixedly connected to the first base by bolts, and the insert block is embedded into the inside of the recess.

[0010] Preferably, a fixing tube is fixedly installed at both ends of the bottom of the second base and the first base. A rotating shaft is rotatably installed inside the fixing tube. Two snap-fit ​​holes are opened at both ends of the rotating shaft. Two square tubes are fixedly installed at the bottom of the first base and the second base. A sliding groove is opened on the opposite side of the two square tubes. A pressing rod is slidably installed at both ends of the sliding groove. A fixing pin is fixedly installed at both ends of the pressing rod. A pressing block is fixedly sleeved on the upper end of the fixing pin. The pressing block and the fixing pin are slidably installed at both ends of the square tube. A snap-fit ​​spring is movably sleeved on the lower end of the fixing pin. The snap-fit ​​spring is located between the fixing pin and the inner wall of the square tube.

[0011] Preferably, rotating blocks are fixedly sleeved at both ends of the rotating shaft, and a movable roller is fixedly connected to one end of the rotating block. The fixing pin is embedded in the locking hole.

[0012] Preferably, an inlet pipe is fixedly installed at one end of the pump head, a limiting groove is formed at one end of the inlet pipe, a slag storage pipe is fixedly connected to the bottom of the inlet pipe, a fixed cap is threadedly installed at the bottom of the slag storage pipe, an insert ring is embedded inside the limiting groove, a filter screen is fixedly installed at one end of the insert ring, a discharge port is formed at the bottom of the filter screen, a stop block is fixedly installed at the bottom of the inner wall of the filter screen, the filter screen is embedded inside the inlet pipe, the discharge port is located at the top of the slag storage pipe, and the top of the filter screen is inclined.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The reaction force of the snap-fit ​​spring causes the fixing pin to snap into the other snap-fit ​​hole of the rotating shaft, so that the moving roller supports the first base and the second base, which facilitates the fixed motor and the pump head to move towards each other. The second base is fixedly connected to the first base by bolts. The first base and the second base can be quickly connected. The split structure and the bottom can be moved by the moving roller, which facilitates the movement and assembly of the chemical process pump. It is flexible to use, easy to move, and improves the flexibility of the device.

[0015] 2. By utilizing the inclined surface of the filter screen, solid particles slide to the bottom of the filter screen. Due to the obstruction of the baffle, the medium flow rate at this point is slower. The solid particles are affected by gravity and fall into the interior of the slag storage pipe and accumulate, reducing the movement of solid particles inside the chemical pump, thereby reducing the damage of solid particles to the pump's inner wall and improving the pump's service life.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 3 As shown, an embodiment of this utility model provides a high-temperature, high-pressure, wear-resistant petrochemical process pump, including a motor assembly 1 and a pump head assembly 2, which are connected to each other.

[0024] like Figure 2 As shown, the pump head assembly 2 includes a first base 21, a connecting pump head 24 is fixedly installed on the top of the first base 21, an embedded groove 22 is provided on the right side of the first base 21, and fixing blocks 23 are fixedly installed at both ends of the right side of the first base 21.

[0025] like Figure 3 As shown, the motor assembly 1 includes a second base 11, a fixed motor 12 is fixedly installed on the top of the second base 11, mounting slots 14 are provided at both ends of the left side of the second base 11, and an insert block 13 is fixedly installed on the left side of the second base 11.

[0026] The fixing block 23 is snapped into the inside of the mounting groove 14 and the second base 11 is fixedly connected to the first base 21 by bolts. The insert block 13 is inserted into the inside of the inner groove 22, which can quickly connect the first base 21 and the second base 11, and connect the pump head 24 and the fixed motor 12 through the flange, so that the chemical process pump can be assembled and disassembled, improving the flexibility of the chemical process pump.

[0027] like Figure 4 As shown, a fixing tube 201 is fixedly installed at both ends of the bottom of the second base 11 and the first base 21. A rotating shaft 202 is rotatably installed inside the fixing tube 201. Two snap-fit ​​holes 205 are opened at both ends of the rotating shaft 202. Two square tubes 206 are fixedly installed at the bottom of the first base 21 and the second base 11. A sliding groove 211 is opened on the opposite side of the two square tubes 206. A pressing rod 207 is slidably installed at both ends of the sliding groove 211. A fixing pin 209 is fixedly installed at both ends of the pressing rod 207. A pressing block 210 is fixedly sleeved on the upper end of the fixing pin 209. The pressing block 210 and the fixing pin 209 are slidably installed at both ends of the square tube 206. A snap-fit ​​spring 208 is movably sleeved on the lower end of the fixing pin 209. The snap-fit ​​spring 208 is located between the fixing pin 209 and the inner wall of the square tube 206.

[0028] The rotating shaft 202 has rotating blocks 203 fixedly sleeved at both ends, and a movable roller 204 is fixedly connected to one end of the rotating block 203. The fixed pin 209 is embedded in the inside of the snap-fit ​​hole 205.

[0029] By pulling the pressing rod 207 in opposite directions, the fixing pin 209 moves inside the square tube 206, compressing the locking spring 208. The fixing pin 209 disengages from the locking hole 205 in the rotating shaft 202, and the rotating shaft 202 is rotated, causing the moving roller 204 to rotate and move out of the first base 21. The moving roller 204 supports the first base 21 and the second base 11, facilitating the movement of the fixed motor 12 and the connected pump head 24. When it is necessary to fix the chemical process pump, by pulling the pressing rod 207 in opposite directions and rotating the rotating shaft 202 in the opposite direction, the moving roller 204 retracts into the first base 21, thus fixing the chemical process pump and facilitating its movement, thereby improving the flexibility of the chemical process pump.

[0030] like Figure 5As shown, an inlet pipe 241 is fixedly installed at one end of the pump head 24. A limiting groove 242 is opened at one end of the inlet pipe 241. A slag storage pipe 247 is fixedly connected to the bottom of the inlet pipe 241. A fixing cap 248 is threadedly installed at the bottom of the slag storage pipe 247. An interlocking ring 243 is embedded inside the limiting groove 242. A filter screen 244 is fixedly installed at one end of the interlocking ring 243. A discharge port 246 is opened at the bottom of the filter screen 244. A stop block 245 is fixedly installed at the bottom of the inner wall of the filter screen 244. The filter screen 244 is embedded inside the inlet pipe 241. The discharge port 246 is located at the top of the slag storage pipe 247. The top of the filter screen 244 is a slope.

[0031] The incoming medium flows into the interior of the pump head 24 from the inlet pipe 241 through the filter screen 244. Solid particles in the medium are intercepted by the filter screen 244. The slope of the filter screen 244 causes the solid particles to slide to the bottom of the filter screen 244. Due to the obstruction of the baffle 245, the medium flow rate at this point is slow. The solid particles are affected by gravity and fall into the interior of the slag storage pipe 247 and accumulate, reducing the movement of solid particles inside the chemical pump and affecting the service life of the chemical pump.

[0032] The working process of this utility model is as follows:

[0033] In use, by pulling the pressing rod 207 in opposite directions, the fixing pin 209 moves inside the square tube 206. The pressing block 210 compresses the locking spring 208, causing the fixing pin 209 to disengage from the locking hole 205 in the rotating shaft 202. Rotating the rotating shaft 202 causes the moving roller 204 to rotate and move out of the first base 21, loosening the pressing rod 207. Through the reaction force of the locking spring 208, the fixing pin 209 engages with another locking hole 205 in the rotating shaft 202, thus affecting the rotation of the rotating shaft 202. Support is provided to prevent the rotating shaft 202 from rotating, so that the moving roller 204 supports the first base 21 and the second base 11, and the fixed motor 12 and the connecting pump head 24 move towards each other. The fixing block 23 is snapped into the inside of the mounting groove 14, and the insert block 13 is inserted into the inside of the inner groove 22. The second base 11 is fixedly connected to the first base 21 by bolts. The first base 21 and the second base 11 can be quickly connected, and the connecting pump head 24 and the fixed motor 12 are connected by flanges, thus assembling the chemical process pump.

[0034] When it is necessary to fix the chemical process pump, by pulling the pressing rod 207 in opposite directions and rotating the rotating shaft 202 in the opposite direction, the moving roller 204 is retracted into the first base 21, and the second base 11 and the first base 21 are fixed to the ground.

[0035] The incoming medium flows into the interior of the pump head 24 from the inlet pipe 241 through the filter screen 244. Through the action of the baffle 245 and the inclined surface of the filter screen 244, the solid particles in the medium are intercepted by the filter screen 244. The inclined surface of the filter screen 244 causes the solid particles to slide to the bottom of the filter screen 244. Due to the obstruction of the baffle 245, the medium flow rate is slower at this point, and the solid particles fall into the interior of the slag storage pipe 247 and accumulate under the influence of gravity.
