Abstract

The application discloses a deep well submersible pump with turbocharging function, and relates to the technical field of submersible pumps, which comprises a driving device, a water outlet mechanism and a water inlet mechanism. The driving device is internally provided with a motor for providing power. The water outlet mechanism is internally provided with a turbine assembly and is connected with the driving device for conveying medium.

When the water pressure of the water inlet pipe is unstable or the water supply pressure is small, the second spring pushes the piston downward, the water at the top end of the pressure pipe is compensated downward, the water flow pressure of the hole groove is kept stable, the water flow pressure fluctuation is reduced, and the motor is effectively protected.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of submersible pumps, in particular to a deep well submersible pump with turbocharging function. BACKGROUND

[0002] With the continuous development of the oil exploitation industry, deep well submersible pumps play a crucial role in the process of oil exploitation. It is mainly used to pump out oil or liquid medium from deep well and transport it to the ground, and its performance and efficiency directly affect the efficiency and cost of oil exploitation. However, in actual application, there are some technical problems to be solved in traditional deep well submersible pumps, which limit their application effect and service life under complex working conditions.

[0003] Firstly, the water inlet hole at the bottom of the water inlet pipe of the deep well submersible pump is easy to be blocked. Because when the water flows through the water inlet pipe, impurities, particles and other impurities carried in the water are easy to accumulate at the water inlet hole, causing the flow area of the water inlet hole to gradually decrease. Once the water inlet hole is blocked, it will seriously affect the normal work of the deep well submersible pump, reduce its working efficiency, and even cause equipment damage. In addition, the pressure fluctuation of water flow is large during the operation of the traditional deep well submersible pump, which is easy to cause impact on the motor and other key components, affecting the service life and stability of the equipment. Therefore, how to effectively avoid the blockage of the water inlet hole at the bottom of the water inlet pipe and reduce the impact of water flow pressure fluctuation on the motor is a problem to be solved in the current deep well submersible pump technology field. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a deep well submersible pump with turbocharging function, which solves the problem of easy blockage of the water inlet hole at the bottom of the water inlet pipe and large water flow pressure fluctuation causing motor damage of the existing deep well submersible pump in the background art.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme: a deep well submersible pump with turbocharging function, comprising:

[0006] a driving device, which is internally provided with a motor for providing power;

[0007] Further comprising:

[0008] a water outlet mechanism, which is internally provided with a turbine assembly connected with the driving device for conveying medium;

[0009] a water inlet mechanism installed on the top of the driving device;

[0010] a pressure stabilizing mechanism located on the top of the water inlet mechanism, which is internally communicated with the water inlet mechanism for stabilizing the water outlet pressure of the water outlet mechanism;

[0011] A circulating assembly is installed on one side of the water outlet mechanism and communicates with the water outlet mechanism and the pressure stabilizing mechanism respectively, for circulating the medium in the pump body.

[0012] Preferably, the water outlet mechanism comprises a water outlet pipe, a turbine set is arranged inside the water outlet pipe, the turbine set is sleeved outside a transmission shaft, the transmission shaft is in transmission connection with a driving motor inside a driving device, a check valve is arranged at one end of the top of the water outlet pipe, the check valve is in sliding connection with one end of the top of the water outlet pipe, and a third spring is arranged at the top of the check valve; by arranging the turbine set inside the water outlet pipe and sleeving the turbine set outside the transmission shaft, the existing turbocharging technology is used, the power of the driving motor inside the driving device can be effectively transmitted to the turbine set by the transmission shaft, and step-by-step pressurization of the medium is realized. The turbocharging technology has been widely applied in the industrial field, and the principle is to compress and accelerate the fluid medium by high-speed rotation of the turbine to improve the pressure and flow of the fluid. In the application, the application of this technology significantly improves the water outlet pressure and flow of the deep well submersible pump, enhances the conveying capacity, meets the high-lift and large-flow requirements under complex working conditions such as deep wells, and ensures that the oil or liquid medium can be smoothly and efficiently pumped out of the deep well and conveyed to the ground.

[0013] Meanwhile, the check valve is in sliding connection with one end of the top of the water outlet pipe and is equipped with a third spring, can keep open state when the water flow is normally conveyed, and makes the medium output smoothly. In the case of shutdown or abnormality, the check valve can be quickly closed under the action of the third spring to prevent the medium from flowing backward. This design not only avoids the impact and damage of the medium flowing backward on the internal structure of the pump body, but also reduces the energy waste caused by the medium flowing backward, improves the operation stability and reliability of the deep well submersible pump, and prolongs the service life of the equipment.

[0014] Preferably, the water inlet mechanism comprises a lifting assembly, a cleaning assembly and a water inlet pipe, the lifting assembly is installed inside the water inlet pipe and is used to drive the cleaning assembly, the water inlet pipe communicates with the pressure stabilizing mechanism, and the cleaning assembly is installed outside the water inlet pipe and a plurality of holes are uniformly arranged on the surface of one end of the bottom of the water inlet pipe for water inlet; by arranging the lifting assembly inside the water inlet pipe and driving the external cleaning assembly by the assembly, the automatic cleaning function of the water inlet holes on the bottom of the water inlet pipe is realized. This design effectively solves the problem that the water inlet holes in the traditional deep well submersible pump are easily blocked by impurities. In actual operation, the water flow enters through the holes on the bottom of the water inlet pipe, drives the lifting assembly to move, and then drives the cleaning assembly to periodically clean the holes, prevents impurities from accumulating, and ensures that the water inlet holes are unobstructed. Meanwhile, the water inlet pipe communicates with the pressure stabilizing mechanism, ensuring the stability and uniformity of the water flow before entering the pump body, and further improving the operation efficiency and stability of the entire deep well submersible pump.

[0015] Preferably, the lifting assembly comprises an impeller, the impeller is located outside the transmission shaft, the bottom of the impeller is welded with one end of the top of the spline shaft, the inside of the spline shaft is a hollow structure, the outer wall of the spline shaft is in sliding connection with the inside of the top tubular structure of the flow resistance plate, the spline shaft is sleeved with a first spring outside, one end of the top of the first spring is welded with the impeller, one end of the bottom of the first spring is welded with the flow resistance plate, the flow resistance plate is in sliding contact with the outer wall of the transmission shaft, the bottom of the flow resistance plate is provided with a lifting block, and the lifting block is in rotary connection with the bottom of the flow resistance plate; the impeller is located outside the transmission shaft, when the water flow passes through the water inlet pipe, the power of the water flow drives the impeller to rotate. The rotation of the impeller is transmitted to the flow resistance plate through the spline shaft, so that the flow resistance plate rotates. Since the inside of the spline shaft is a hollow structure, and the outer wall is in sliding connection with the inside of the top tubular structure of the flow resistance plate, the structure design enables the flow resistance plate to move up and down under the action of the water flow. At the same time, the first spring is sleeved outside the spline shaft and is welded with the impeller and the flow resistance plate respectively, which provides elastic support and reset function for the movement of the flow resistance plate; when the water flow passes through the water inlet pipe, the kinetic energy of the water flow will cause the flow resistance plate to be subjected to a large resistance, thereby pushing the flow resistance plate and the lifting block to move upward. When the flow resistance plate rotates to the position aligned with the lifting block, the water flow resistance suddenly decreases, at this time the elastic force of the first spring will make the flow resistance plate and the lifting block quickly reset downward. The periodic up and down movement is transmitted through the connecting rod and the scraper to realize the automatic cleaning of the water inlet hole groove at the bottom of the water inlet pipe.

[0016] Preferably, the cleaning assembly comprises a sealing plate, the sealing plate is symmetrically distributed on both sides of the outer wall of the water inlet pipe, the sealing plate is in close contact and sliding contact with the outer wall of the water inlet pipe, the outer wall of the water inlet pipe is symmetrically provided with two strip-shaped hole grooves, the sealing plate is connected with the end of the lifting block through bolts, one end of the bottom of the sealing plate is fixedly connected with the connecting rod, the connecting rod is welded with a plurality of scrapers, the scraper is in the form of a ring structure, and the scraper is in sliding contact with the outer wall of the water inlet pipe; the sealing plate is symmetrically distributed on both sides of the outer wall of the water inlet pipe and is in close contact and sliding contact with the outer wall of the water inlet pipe. This design ensures that the sealing plate can closely follow the outer wall of the water inlet pipe during movement, thereby realizing effective coverage and cleaning of the water inlet hole groove. The sealing plate is connected with the end of the lifting block through bolts, which not only ensures the stability of the structure, but also allows the sealing plate to move synchronously with the lifting block; one end of the bottom of the sealing plate is fixedly connected with the connecting rod, and the connecting rod is welded with a plurality of scrapers. So that the scraper can move up and down through the linkage of the connecting rod and the sealing plate. The scraper is in the form of a ring structure and is in sliding contact with the outer wall of the water inlet pipe, which enables the scraper to fully cover the water inlet hole groove at the bottom of the water inlet pipe, thereby realizing omnidirectional cleaning of the hole groove.

[0017] Preferably, the pressure stabilizing mechanism comprises a pressure stabilizing tube, one end of the bottom of the pressure stabilizing tube is integrally formed with the water inlet pipe, a pressure pipe is arranged in the pressure stabilizing tube, the bottom of the pressure pipe is annularly and equidistantly provided with hole grooves, a piston is arranged in the pressure pipe, the piston is in sliding contact with the inner wall of the pressure pipe, and a second spring is arranged on the top of the piston; a piston is arranged in the pressure pipe, the piston is in sliding contact with the inner wall of the pressure pipe, and a second spring is arranged on the top of the piston. When water flows into the hole grooves at the bottom of the pressure pipe, the pressure of the water flow will push the piston to move upwards, and at the same time, the second spring is compressed. This design enables the piston to move up and down according to the change of the water flow pressure, so as to adjust the water pressure in the pressure pipe; when the water pressure in the water inlet pipe is unstable or the water supply pressure is small, the second spring will push the piston downwards, so that the water at the top end in the pressure pipe can be compensated downwards, thereby keeping the water flow pressure stable through the hole grooves at the bottom of the pressure pipe. This automatic adjustment mechanism can effectively reduce the fluctuation of the water flow pressure and ensure the stability of the water outlet pressure.

[0018] Preferably, the pressure pipe is internally provided with a transmission shaft, the transmission shaft is provided with two, the first connecting block and the second connecting block are fixedly installed at the ends of the two transmission shafts, the first connecting block and the second connecting block are tightly fitted with each other, and the first connecting block and the second connecting block are both made of rubber, the second connecting block is rotatably connected with a pressing plate at the top, and the pressing plate is connected with the top of the pressure pipe through fastening bolts. Through the tight fitting of the first connecting block and the second connecting block, the connection of the two transmission shafts is realized by using friction force. When the system is overloaded, the lower transmission shaft will idle, preventing the transmission shaft from being directly damaged by overload.

[0019] Preferably, the circulating assembly comprises a circulating pipe, one end of the bottom of the circulating pipe is communicated with the pressure stabilizing pipe, one end of the top of the circulating pipe is communicated with the water outlet pipe, a limiting ring is arranged at one end of the bottom of the circulating pipe, the limiting ring is welded with the inner wall of the circulating pipe, a connecting shaft is arranged in the limiting ring, there is a gap between the connecting shaft and the limiting ring, an end cover is welded to one end of the connecting shaft, a hollow block is sleeved on the other end of the connecting shaft, a through hole is arranged in the hollow block for medium circulation, and a fourth spring is arranged between the hollow block and the limiting ring. One end of the bottom of the circulating pipe is communicated with the pressure stabilizing pipe, and one end of the top of the circulating pipe is communicated with the water outlet pipe. This design enables the water flow to form a closed circulation path in the pump body. When the water outlet or the water inlet is blocked, the water flow can return to the pressure stabilizing pipe through the circulating pipe, avoiding damage to the equipment caused by pressure accumulation.

[0020] The application provides a deep well submersible pump with a turbocharging function.

[0021] This deep-well submersible pump with turbocharging function operates by a drive motor within the drive unit that rotates the transmission shaft, thereby driving the turbine to progressively increase the pressure and output water from the top of the outlet pipe. As the water flows at high speed through the inlet pipe, it drives the impeller to rotate, which in turn drives the baffle plate to rotate via a splined shaft. When the baffle plate and the lifting block are misaligned, the water flow resistance increases, pushing the baffle plate and lifting block upwards, which in turn moves the sealing plate and scraper upwards. When the baffle plate rotates to align with the lifting block, the water flow resistance decreases, and the first spring pushes the lifting block and scraper downwards to reset. This allows the scraper to scrape up and down using the kinetic energy of the water flow, self-cleaning the bottom groove of the inlet pipe and effectively preventing blockage of the inlet hole. Simultaneously, after entering the pressure pipe, the water flows through the bottom groove and is discharged to the pressure stabilizing pipe. Due to the small flow area of ​​the groove, the water pressure in the pressure pipe increases, causing the water flow to lift the piston and compress the second spring. When the water pressure in the inlet pipe is unstable or the water supply pressure is low, the second spring pushes the piston downward, causing the water at the top of the pressure pipe to flow downward to compensate, maintaining a stable water flow pressure in the slot and reducing water flow pressure fluctuations, thereby effectively protecting the motor.
