Description

Technical Field

[0001] This invention belongs to the field of plunger pump skid technology, specifically relating to a high-pressure reciprocating plunger pump skid for high-temperature desert and explosion-proof environments. Background Technology

[0002] High-pressure reciprocating plunger pump skids are core integrated equipment for water injection pressurization, media transportation, and pressure replenishment operations in oil and gas fields. With their advantages of stable pressure output, large pressure ratio, and adaptability to high-pressure conditions, they are widely used in field oil and gas extraction, oil and gas gathering and transportation, and industrial high-pressure fluid supply. In this study, "high temperature" refers to an operating environment temperature of 50-60 degrees Celsius, "explosion-proof" refers to the operating environment of transporting crude oil in desert oilfields, and "high pressure" refers to crude oil connection at pressures between 20 MPa and 100 MPa.

[0003] The existing high-pressure reciprocating plunger pump skids for explosion-proof environments have the following problems during use: 1. Existing high-pressure reciprocating plunger pump skids are used outdoors, especially in high-temperature environments such as deserts. The plunger pump skid body needs to be cooled. During the cooling process, a filter screen is needed to filter and remove impurities from the air drawn in by the fan. However, the outdoor environment is complex, and the filter screen is easily clogged during dust removal, which affects the efficiency of subsequent processing.

[0004] 2. Currently, most conventional high-pressure reciprocating pump skids are general-purpose integrated structures with limited functionality. They can only meet the needs of normal temperature, indoor, and ordinary outdoor operating environments without explosion-proof requirements, resulting in extremely limited applicability. Conventional pump skids lack professional explosion-proof electrical configurations, spark-free transmission structures, and anti-static protection systems, thus failing to meet safety production standards for explosive hazardous areas. Summary of the Invention

[0005] The purpose of this invention is to provide a simple and rationally designed high-pressure reciprocating plunger pump skid for high-temperature desert and explosion-proof environments in order to solve the above problems.

The output end of the coupling is fixedly connected to the power input end of the reciprocating pump skid body. An outlet pipe and an inlet pipe are provided on the hydraulic end.

[0009] Preferably, an explosion-proof air conditioner outdoor unit is fixedly installed inside the top of the bracket, and the explosion-proof air conditioner outdoor unit is fixedly connected to an air conditioner indoor unit through a flexible hose. The air conditioner indoor unit is fixedly installed inside the top rear side of the external explosion-proof cabinet. A controller is provided inside the top left side of the bracket, and the controller is electrically connected to the explosion-proof air conditioner outdoor unit.

[0010] Preferably, the cleaning component includes an annular guide rail fixedly installed inside the fixed cover, an annular cam fixedly installed on the inner side of the annular guide rail, an installation ring fixedly sleeved on the outer side of the central shaft of the fan blade, a fixing part is provided between the installation ring and the annular guide rail, and a cleaning part is provided on the fixing part.

[0011] Preferably, the fixing part includes multiple guide rollers slidably disposed inside the annular guide rail. The multiple guide rollers are rotatably connected to mounting plates via rotating shafts. A fixing ring is fixedly installed between the mounting plates. A mounting seat is fixedly installed at the end of the mounting plate. A limiting roller is rotatably connected to the mounting seat. The limiting roller has a limiting groove that engages with the mounting ring. A ratchet is fixedly installed on the side of the mounting plate away from the guide rollers.

[0012] Preferably, a linear slide rail is fixedly installed on the mounting plate. A fixed groove is provided on the linear slide rail. A guide slider is slidably connected to the linear slide rail. A stop block is fixedly installed on the guide slider and slidably connected inside the fixed groove. A spring telescopic rod is fixedly installed between the stop block and the top of the linear slide rail. A cleaning brush is fixedly installed on the side of the guide slider away from the linear slide rail. A guide pulley that cooperates with the annular cam is installed on the top of the cleaning brush through a mounting rod.

[0013] Preferably, the bristles of the cleaning brush are attached to the filter screen, and the fan blades are provided with mounting grooves, on which a unidirectional rotating pawl is rotatably mounted.

[0014] Preferably, the liquid cooling frame is hollow inside, and the hollow cavity is a flow guide groove. The heat dissipation fins are hollow inside, and the hollow area is a flow channel groove. The heat dissipation fins are connected to the upper and lower ends of the liquid cooling frame, and several vortex boxes are fixedly installed on the connecting pipe.

[0015] Preferably, a fixed rod is rotatably installed inside the vortex box, and several driving blades are fixedly installed on the top of the fixed rod. The driving blades are located inside the vortex box, and a water outlet is opened at the bottom of the vortex box. Several stirring blades are fixedly connected to the bottom of the fixed rod after it rotates through the water outlet.

[0016] The beneficial effects of this invention are as follows: 1. Unlike existing technologies, this invention features an independent explosion-proof air conditioning system. The outdoor unit of the explosion-proof air conditioner, together with the indoor unit of the cabinet air conditioner, continuously cools the explosion-proof electrical control cabinet, offsetting the 60°C high temperature of the desert sun. This prevents the electrical control and instrument components from aging and short-circuiting due to high temperatures, ensuring the long-term stable operation of the explosion-proof electrical system. At the same time, it solves multiple industry problems such as insufficient high-temperature resistance of traditional equipment, dust blockage, lack of explosion protection, and lack of anti-tampering records for the distribution cabinet.

[0017] 2. Unlike existing technologies, this invention achieves rapid heat dissipation of the lubricating oil inside the reciprocating pump skid body through the combined use of an air-cooled cleaning mechanism and a circulating heat dissipation mechanism, avoiding the problem of oil overheating. Furthermore, the lubricating oil circulating heat dissipation mechanism adopts a hollow finned oil cooling structure, which, together with the pipeline series vortex box, generates turbulent disturbance as the oil flows through the vortex box, breaking the heat exchange boundary layer and significantly improving heat exchange efficiency. This solves the problems of excessively high oil temperature at the pump power end, lubricating oil viscosity failure, and accelerated component wear in high-temperature desert environments.

[0018] 3. Unlike existing technologies, the servo motor in the air-cooled cleaning mechanism achieves heat dissipation through suction when rotating forward, and drives the cleaning component to start working when rotating in reverse. The cleaning brush in the cleaning component rotates synchronously and cleans in a reciprocating linear motion, which facilitates the removal of impurities from the filter screen. Furthermore, when the servo motor drives the fan blades to rotate in reverse, it blows air in the opposite direction, further improving the cleaning effect of the filter screen, thus realizing a linkage cleaning mode of "forward rotation for heat dissipation and reverse rotation for cleaning".

[0019] 4. Unlike existing technologies, this invention features a skid-mounted integrated system with lifting rings at the four corners of the base, allowing for overall lifting and transportation. It is suitable for desert environments without fixed machine rooms and for temporary mobile operations. The electrical control cabinet door is equipped with a reed induction switch and a strong magnet triggering structure. The opening of the cabinet door generates a timestamped record and stores it locally with encryption, distinguishing between authorized maintenance openings and illegal forced dismantling, thus meeting the safety supervision requirements of oilfield explosion-proof areas.

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example: Please refer to Figure 1 , Figure 2 and Figure 3A high-pressure reciprocating plunger pump skid for high-temperature desert and explosion-proof environments includes a base 1, which is an integrally welded anti-corrosion steel skid. Lifting rings 16 are fixedly installed at the four corners of the bottom of the base 1 for lifting and transporting the entire unit, suitable for mobile operations in desert environments. An external explosion-proof cabinet 2 is installed on the top left of the base 1, and a bracket 3 is installed on the top right of the base 1. A high-pressure reciprocating pump skid body 6 is installed on the top of the base 1. A hydraulic end 7 is installed at the output end of the reciprocating pump skid body 6, used for crude oil intake and high-pressure boosting discharge, suitable for high-pressure crude oil transportation conditions of 20MPa to 100MPa. Both the reciprocating pump skid body 6 and the hydraulic end 7 are existing technologies. The base 1 contains... A circulating cooling mechanism 9 is installed in the middle of the unit. This mechanism is specifically designed to provide forced circulation cooling of the lubricating oil inside the power end of the high-pressure reciprocating pump skid body 6, reducing the temperature rise of the crankshaft and crosshead friction at the power end. A wind-cooling cleaning mechanism 8 is installed on the circulating cooling mechanism 9. This mechanism provides forced convection cooling air to the circulating cooling mechanism 9, improving oil cooling efficiency, and automatically cleans accumulated sand and dust, adapting to the windy and sandy conditions of the desert. Thus, the wind-cooling cleaning mechanism 8 has the dual function of forced air cooling in forward rotation and cleaning blockages in reverse rotation. An electrical control cabinet 13 is installed inside the external explosion-proof cabinet 2, integrating a PLC, a pressure transmitter signal acquisition module, a storage unit, and an RTC. The clock module and other modules are existing technologies in the electrical control cabinet 13. A sealed reed induction switch is set on the inner edge of the cabinet door of the electrical control cabinet 13. A strong magnet is set at the corresponding position on the door frame of the electrical control cabinet 13. When the cabinet door is closed normally, the strong magnet is close to the reed induction switch, the switch remains on, and the system judges it to be in a normal closed state. When the cabinet door is opened by force, the strong magnet moves away, the reed induction switch is opened, the PLC immediately captures the level change, and synchronously reads the RTC timestamp to realize the whole process of evidence collection for illegal cabinet dismantling and unauthorized parameter tampering.

[0024] Please see Figure 2 , Figure 3 and Figure 4An explosion-proof motor 14 is fixedly installed inside the rear of the external explosion-proof cabinet 2. The output end of the explosion-proof motor 14 is sealed and rotates through the external explosion-proof cabinet 2 and is fixedly connected to a coupling. The output end of the coupling is fixedly connected to the input end of the power end of the reciprocating pump skid body 6. An outlet pipe 10 and an inlet pipe 11 are provided on the hydraulic end 7. The oil storage tank of the power end of the reciprocating pump skid body 6 is fixedly connected to the input end of the circulating pump 12 through a pipe. The output end of the circulating pump 12 is fixedly connected to the circulating pipe 17. An explosion-proof air conditioner outdoor unit 4 is fixedly installed inside the top of the bracket 3. All electrical components of the explosion-proof air conditioner outdoor unit 4 are explosion-proof and the explosion-proof air conditioner outdoor unit 4 is existing technology. The explosion-proof air conditioner outdoor unit 4 is fixedly connected to the air conditioner indoor unit 15 through a flexible hose. The air conditioner indoor unit 15 is fixedly installed inside the rear of the top of the external explosion-proof cabinet 2. A controller 5 is provided inside the top left of the bracket 3. The controller 5 is electrically connected to the explosion-proof air conditioner outdoor unit 4. A temperature sensor is provided inside the external explosion-proof cabinet 2. The temperature sensor is electrically connected to the controller 5.

[0025] During use, the maximum ambient temperature in the desert environment can reach 60℃. The temperature sensor collects the internal temperature of the external explosion-proof cabinet 2 in real time, and the temperature data is transmitted to the controller 5. When the temperature exceeds the limit, the controller 5 automatically starts the explosion-proof air conditioner outdoor unit 4. The air conditioner indoor unit 15 continuously cools the electrical components inside the electrical control cabinet 13 to avoid insulation aging and instrument failure caused by high temperature. The entire process is explosion-proof and there is no risk of ignition. The explosion-proof motor 14 is the power source of this equipment. The output end of the explosion-proof motor 14 is sealed through the external explosion-proof cabinet 2 to prevent oil and gas in the cabinet from leaking out through the shaft gap. The coupling realizes the power transmission and stably drives the plunger pump to reciprocate. The hydraulic end 7 is equipped with the liquid outlet pipe 10 and the liquid inlet pipe 11 respectively. The liquid inlet pipe 11 delivers low-pressure crude oil medium into the pump head. After being pressurized by the plunger, high-pressure crude oil is output to the outside through the liquid outlet pipe 10.

[0026] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The air-cooled cleaning mechanism 8 includes a fixed cover 82 located in the middle of the bracket 3. The fixed cover 82 is an integral enclosed metal shell, which serves to gather airflow, prevent dust, and support all components. A filter screen 83 is located on the right side of the fixed cover 82. The filter screen 83 blocks desert sand from entering the airflow and prevents the heat dissipation channel from being blocked. A servo motor 81 is fixedly installed on the fixed cover 82. The output end of the servo motor 81 rotates through the center of the filter screen 83 and is fixedly sleeved with a fan blade 85. The servo motor 81 drives the fan blade 85 to rotate and generate a transverse forced convection airflow. A cleaning component 84 is located inside the fixed cover 82.

[0027] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The cleaning component 84 includes an annular guide rail 841 fixedly installed inside the fixed cover 82. An annular cam 842 is fixedly installed on the inner side of the annular guide rail 841. An installation ring 88 is fixedly sleeved on the outer side of the central shaft of the fan blade 85. A fixing part 843 is provided between the installation ring 88 and the annular guide rail 841. A cleaning part 844 is provided on the fixing part 843. The fixing part 843 includes multiple guide rollers 8434 slidably installed inside the annular guide rail 841. The multiple guide rollers 8434 are rotatably connected to the mounting plate 8432 through a rotating shaft. A fixing ring 8431 is fixedly installed between the mounting plates 8432. A mounting seat 8435 is fixedly installed at the end of the mounting plate 8432. A limiting roller 8436 is rotatably connected to the mounting seat 8435. A limiting groove is opened on the limiting roller 8436 to engage with the mounting ring 88. A ratchet 8433 is fixedly installed on the side of the mounting plate 8432 away from the guide roller 8434.

[0028] Please see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 A linear slide rail 8441 is fixedly mounted on the mounting plate 8432. A fixing groove 8443 is provided on the linear slide rail 8441. A guide slider 8444 is slidably connected to the linear slide rail 8441. A stop block is fixedly mounted on the guide slider 8444 and slidably connected inside the fixing groove 8443. A spring telescopic rod 8442 is fixedly mounted between the stop block and the top of the linear slide rail 8441. A cleaning brush 8445 is fixedly mounted on the side of the guide slider 8444 away from the linear slide rail 8441. A guide pulley 8446 that works with the annular cam 842 is mounted on the top of the cleaning brush 8445 via a mounting rod. The bristles of the cleaning brush 8445 are in contact with the filter screen 83. A mounting groove 87 is provided on the fan blade 85. A unidirectional rotating pawl 86 is rotatably mounted on the mounting groove 87. The pawl 86 is prior art and will not be described in detail here.

[0029] In use, the servo motor 81 is started, and its output drives the fan blade 85 to rotate forward, drawing outside air from the filter 83 and blowing it towards the circulating cooling mechanism 9, achieving forced cooling through forward rotation. Due to the cooperation of the pawl 86 and ratchet 8433, the fan blade 85 does not rotate the fixed part 843 and the cleaning part 844 when rotating forward. When cleaning the filter 83 is required, the servo motor 81 is reversed, causing the fan blade 85 to rotate in the opposite direction, simultaneously driving the pawl 86 to rotate in the opposite direction, which in turn drives the ratchet 8433 and its mounting plate 8432 to rotate in the opposite direction, simultaneously driving the linear slide rail 8441 and its guide slider 8444 to rotate, which in turn drives the cleaning brush 8445 to rotate, using the rotation of the cleaning brush 8445 to clean the filter 83. Simultaneously, as the cleaning brush 8445 rotates, it also drives the guide pulley 8446 to rotate. When the guide pulley 8446 contacts the protruding part of the annular cam 842, it drives the guide pulley 8446 and the cleaning brush 8445 on it to move downwards, simultaneously driving the guide slider 8444 to move downwards. At the same time, it drives the spring telescopic rod 8442 to extend. When the guide pulley 8446 contacts the recessed part of the annular cam 842, under the action of the restoring force of the spring telescopic rod 8442, it drives the cleaning brush 8445 to move upwards. This achieves the cleaning brush 8445 rotating and reciprocating up and down at the same time, which facilitates the circumferential rotation cleaning and radial reciprocating linear cleaning of the filter screen 83. The cleaning effect is good, and when the fan blade 85 rotates in the opposite direction, it achieves back-blowing cleaning, further improving the cleaning effect.

[0030] Please see Figure 5 , Figure 6 , Figure 11 and Figure 12The circulating heat dissipation mechanism 9 includes a liquid-cooled frame 91 fixedly installed on one side of the fixed cover 82. Several heat dissipation fins 92 are fixedly installed inside the liquid-cooled frame 91. Ventilation holes are located between adjacent heat dissipation fins 92. Cool air blown out by the fan blades 85 passes through the ventilation holes and fully exchanges heat with the fins. A circulation pipe 17 is fixedly installed through the rear top of the liquid-cooled frame 91, and a connecting pipe 95 is installed on the circulation pipe 17. A return pipe 18 is fixedly connected to the rear bottom of the liquid-cooled frame 91. The return pipe 18 is fixedly connected to the oil reservoir at the power end of the reciprocating pump skid body 6. The liquid-cooled frame 91 is hollow inside, and the hollow cavity is a guide channel 93. The heat dissipation fins 92 are also hollow inside, and the hollow area is a flow channel 96. The heat dissipation fins 92 are connected to the upper and lower ends of the liquid-cooled frame 91. High-temperature lubricating oil enters the guide channel 93 of the liquid-cooled frame 91 from the circulation pipe 17 and is evenly distributed into the flow channel 96 inside each heat dissipation fin 92, significantly improving lubrication. The lubricating oil has a large heat exchange contact area with the air. Several vortex boxes 94 are fixedly installed on the connecting pipe 95. A fixed rod 98 is rotatably installed inside the vortex box 94. Several drive blades 97 are fixedly installed on the top of the fixed rod 98. The drive blades 97 are located inside the vortex box 94. A water outlet is opened at the bottom of the vortex box 94. The diameter of the connecting pipe 95 is larger than the diameter of the water outlet. Several stirring blades 99 are fixedly connected after the bottom of the fixed rod 98 rotates through the water outlet. When the high-temperature lubricating oil flows through the inside of the vortex box 94, the high-speed oil flow impacts the drive blades 97, causing the fixed rod 98 to rotate as a whole. The fixed rod 98 simultaneously drives the bottom stirring blades 99 to stir the lubricating oil flowing out of the vortex box 94, breaking the stable laminar flow state of the lubricating oil and forming strong turbulence. This disrupts the heat exchange boundary layer and greatly improves the heat exchange efficiency between the heat dissipation fins 92 and the lubricating oil, solving the problem of excessive oil temperature at the pump power end in the high-temperature desert environment.

[0031] It should be noted that this high-temperature desert environment and explosion-proof environment high-pressure reciprocating plunger pump skid is used by mounting the entire equipment on a trailer. The trailer is driven to the vicinity of the oilfield wellhead, and the inlet pipe 11 is connected to the oil storage tank near the wellhead. The three-phase power supply powers the three-plunger reciprocating pump, and the equipment starts working, pumping crude oil from the storage tank to form a pressure of 20MPa. The temperature sensor collects the internal temperature of the external explosion-proof cabinet 2 in real time, and the temperature data is transmitted to the controller 5. When the temperature exceeds the standard, the controller 5 automatically starts the explosion-proof air conditioner outdoor unit 4. The air conditioner indoor unit 15 continuously cools the electrical components inside the electrical control cabinet 13, starts the servo motor 81, and the output of the servo motor 81 drives the fan blade 85 to rotate forward, drawing outside air from the filter screen 83 and blowing it to the circulating heat dissipation mechanism 9 to achieve forced cooling in forward rotation. When it is necessary to clean the filter screen 83, the servo motor 81 is reversed, driving the fan blade 85 to rotate in the opposite direction, and simultaneously driving the pawl 86 to rotate in the opposite direction. This causes the ratchet 8433 and its mounting plate 8432 to rotate in the opposite direction, simultaneously causing the linear slide rail 8441 and its guide slider 8444 to rotate, which in turn causes the cleaning brush 8445 to rotate. The rotation of the cleaning brush 8445 cleans the filter screen 83. At the same time, as the cleaning brush 8445 rotates, it also causes the guide pulley 8446 to rotate. When the guide pulley 8446 contacts the protruding part of the annular cam 842, it causes the guide pulley 8446 and its cleaning brush 8445 to move downwards, simultaneously causing the guide slider 8444 to move downwards. At the same time, it causes the spring telescopic rod 8442 to extend. When the guide pulley 8446 contacts the recessed part of the annular cam 842, under the action of the restoring force of the spring telescopic rod 8442, it causes the cleaning brush 8445 to move upwards, realizing the cleaning brush 8445 rotating and reciprocating up and down at the same time. The circulating heat dissipation mechanism 9 dissipates heat from the high-temperature lubricating oil.

[0032] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
