With global water shortages and growing awareness of environmental protection, desalination has become an important solution to water resource issues. High-pressure desalination pumps used in the desalination sector are primarily made of duplex stainless steel.

[0003] For example, a reciprocating high-pressure pump with the announcement number CN212376861U, through the setting of a locking device, utilizes the mutual cooperation between the support frame, baffle, locking device and positioning plate, so that the locking rod can complete the rapid locking between the support frame and the positioning plate, so that the support frame can be stably fixed on the top surface of the pad, so that the reciprocating pump can be quickly replaced when damaged, and the efficiency of liquid suction will not be affected due to long disassembly and installation time, thereby improving the practicality of the reciprocating high-pressure pump.

[0004] The above-mentioned patent lacks corresponding monitoring measures at the inlet and outlet positions of the high-pressure pump. If the high-pressure pump is blocked, the maintenance signal cannot be received in time, which will generate loud noise and reduce the service life of the high-pressure pump.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1 - Figure 5The present invention provides a technical solution: a seawater desalination high-pressure pump with monitoring and protection functions, including a water pump motor part 100, a water pump head 101 is provided at the front end of the water pump motor part 100, a base 104 is provided at the bottom of the water pump head 101, a water inlet 102 and a water outlet 103 are provided on the front surface and the upper surface of the water pump head 101 respectively, and a monitoring mechanism 200 for monitoring the water inlet 102 and the water outlet 103 is provided on the outside of the water pump motor part 100. By providing the monitoring mechanism 200, the surface temperature of the water inlet 102 and the water outlet 103 can be monitored at any time, and the monitored temperature can be uploaded to the DCS in real time. If the surface error between the two is high, the temperature signal can be uploaded to the DCS at the same time. An alarm will be issued to prompt the staff to carry out maintenance in time. If the temperature sensor 2063 has a problem and cannot monitor the temperature, a new temperature sensor 2063 can be replaced without suspending the operation of the high-pressure pump to continue monitoring, thereby reducing the loss of suspending the replacement of the high-pressure pump. The monitoring mechanism 200 includes two distribution rings 202 respectively located outside the water inlet 102 and the water outlet 103. The circumferential surface of the distribution ring 202 is provided with a plurality of sensor components 206 for detecting the surface of the water inlet 102. The two distribution rings 202 are both provided with a transmission shaft 203, which supports the two distribution rings 202 respectively. A drive conversion component 204 is provided between the two transmission shafts 203;

[0036] The monitoring mechanism 200 also includes a mounting frame 201 that supports a horizontally distributed transmission shaft 203, thereby facilitating support for the distribution ring 202;

[0037] The drive conversion component 204 includes a lower worm gear 2042 fixedly sleeved on the horizontally distributed transmission shaft 203, and an upper worm gear 2041 fixedly sleeved on the lower end of the vertically distributed transmission shaft 203. The upper worm gear 2041 and the lower worm gear 2042 are meshed and connected. The meshing connection between the two facilitates the synchronous rotation of the horizontal transmission shaft 203 and the vertical transmission shaft 203, thereby allowing the two distribution rings 202 to rotate to adjust the position of the temperature sensor 2063, ensuring that when the previous temperature sensor 2063 fails, a new temperature sensor 2063 can be replaced without suspending the operation of the entire high-pressure pump, thereby facilitating continuous temperature monitoring of the water inlet 102 and the water outlet 103;

[0038] The sensing component 206 includes a temperature sensor 2063 attached to the surface of the water inlet 102. At the same time, a temperature sensor 2063 is also provided on the surface of the water outlet 103, which can monitor the surface temperatures of the water inlet 102 and the water outlet 103. If the temperature difference is too high, it means that the water pump is stuffy or has other faults, which can easily remind the staff to carry out timely maintenance.

[0039] In this embodiment, preferably, the drive conversion component 204 also includes a supporting transverse plate 2043 fixed on the upper surface of the mounting frame 201. The supporting transverse plate 2043 can support the vertically distributed transmission shaft 203 without affecting the in-situ rotation of the vertically distributed transmission shaft 203. The inner end of the supporting transverse plate 2043 is sleeved on the vertically distributed transmission shaft 203. A supporting frame 207 is provided on the lower surface of the mounting frame 201, and the supporting frame 207 supports the U-shaped mounting frame 201.

[0040] In this embodiment, preferably, the sensing component 206 also includes a plurality of electric telescopic rods 2061 vertically installed on the distribution ring 202, and the outer ends of the electric telescopic rods 2061 are connected to the temperature sensor 2063. The length of the electric telescopic rods 2061 is retractable to facilitate adaptation to the rotation of the distribution ring 202. At the same time, the electric telescopic rods 2061 facilitate driving the temperature sensor 2063 to move and contact the surface of the water outlet 103.

[0041] In this embodiment, preferably, a fixed vertical plate 2062 is provided on the upper surface of the water pump head 101, and an adhesive layer for bonding the protective film 2064 is provided on the surface of the fixed vertical plate 2062. The adhesive layer is used to stick the protective film 2064 off, so that the temperature sensor 2063 can monitor the surface temperature of the water inlet 102. The protective film 2064 is adhered to the surface of the temperature sensor 2063, and the protective film 2064 can protect the surface of the temperature sensor 2063.

[0042] In this embodiment, preferably, a drive motor 205 is provided on the right side of the mounting frame 201, and the drive motor 205 is connected to the right end of the horizontally distributed transmission shaft 203. A rotating shaft is embedded between the transmission shaft 203 and the mounting frame 201, and the drive motor 205 is used to drive the transmission shaft 203 to rotate in place.

[0043] In summary, the entire monitoring mechanism 200 is fixed on the surface of the base 104. At this time, the temperature sensors 2063 on the two distribution rings 202 are respectively attached to the surfaces of the water inlet 102 and the water outlet 103, and the surface temperatures of the water inlet 102 and the water outlet 103 are monitored in real time. If the temperature difference is large, the temperature data is uploaded to the DCS and an alarm is issued to prompt the staff to carry out maintenance in time. If the temperature sensor 2063 fails, the temperature monitoring of the water inlet 102 and the water outlet 103 is interrupted. At this time, a new temperature sensor 2063 needs to be replaced. The DCS sends a signal to the drive motor 205 to work, driving the horizontally distributed transmission shaft 203 and the lower worm gear 2042 thereon to rotate, while the upper worm gear 2041 meshing with it and the vertically distributed transmission shaft 203 rotate. The two transmission shafts 203 rotate synchronously, which can drive the two distribution rings 202 to rotate synchronously. At the same time, the electric telescopic rod 2061 works to drive the temperature sensor 2 063 moves outward away from the water outlet 103 without affecting the rotation of the distribution ring 202 and the replacement of the temperature sensor 2063. The damaged temperature sensor 2063 on the water inlet 102 or the water outlet 103 is rotated outward, and the new temperature sensor 2063 is rotated toward the water inlet 102 until the new temperature sensor 2063 is rotated to a suitable position outside the water inlet 102. The electric telescopic rod 2061 works to drive the temperature sensor 2063 to move and contact the surface of the water outlet 103, so that the temperature sensor 2063 can monitor the surface temperature of the water inlet 102 again, ensuring that the monitored temperature continues to be uploaded, and at this time the drive motor 205 stops working, keeping the surface temperature of the water inlet 102 and the water outlet 103 always monitored, and the temperature sensor 2063 is replaced in time, and the high-pressure pump will not be interrupted to replace the temperature sensor 2063, thereby reducing the economic loss caused by the interruption of the high-pressure pump.

[0046] In this embodiment, preferably, a bearing portion 105 is embedded in the water pump head 101, and a sensor and a vibration monitoring element for monitoring the end surface temperature of the bearing portion 105 are provided on the inner wall of the water pump head 101, so as to monitor the temperature and vibration of the bearing portion 105 at any time and understand the status of the bearing portion 105. A pump shaft 106 is provided inside the bearing portion 105, and an axis detection component 400 for monitoring the front end of the pump shaft 106 is provided inside the water pump motor portion 100. By providing the axis detection component 400, it does not affect the rotation of the pump shaft 106, but can monitor the end of the pump shaft 106, and can monitor the axial displacement change of the pump shaft 106. When the position variable reaches a certain value, it indicates that the wear of the balancing disk has reached the limit, the on-site indicator light shows abnormality, and transmits an alarm signal to the DCS. On the contrary, the balancing disk indicator light shows normal Whether it is normal or abnormal, its signal will be transmitted to the DCS. The shaft detection component 400 includes an annular slide 401 that is fitted onto the inner wall of the water pump motor part 100. A guide slider 402 is slidably provided in the annular slide 401, which can drive the guide slider 402 to rotate as the pump shaft 106 rotates, so that the shaft displacement probe 403 is always located outside the pump shaft 106 for monitoring. The shaft displacement probe 403 is vertically provided at the front end of the pump shaft 106, and two fixed rods 404 are vertically provided at the front end of the pump shaft 106. A stand 405 is vertically provided at the front end of the shaft displacement probe 403, and both ends of the stand 405 are slidably sleeved on the fixed rod 404, and the lower end of the stand 405 is fixed on the upper surface of the guide slider 402, so that the stand 405 and the guide slider 402 can slide in the annular slide 401 conveniently as the pump shaft 106 rotates.

[0047] Example 3

[0048] Reference Figure 8 and Figure 9 , which is the third embodiment of the present invention.

[0049] In this embodiment, preferably, a buffer cooling mechanism 300 is provided at the bottom of the water pump motor part 100. By providing the buffer cooling mechanism 300, it can not only provide buffer support for the bottom of the water pump motor part 100, but also utilize the vibration of the water pump motor part 100 on the arc buffer plate 301 to draw external air into the piston cylinder 3031 and cool it through the refrigeration mesh plate 3034, and the cooled gas is discharged through the air holes on the distribution pipe 305 to act on the surface of the water pump motor part 100, thereby playing a cooling and heat dissipation role. The buffer cooling mechanism 300 includes a curved buffer plate 301 supporting the lower surface of the water pump motor part 100, and a buffer seat 302 is provided on the lower surface of the front and rear ends of the curved buffer plate 301. The buffer seat 302 includes a buffer spring and a telescopic tube, which plays a buffering role on the vibration of the water pump motor part 100. An air supply component 303 is provided on the right side of the curved buffer plate 301. The buffer cooling mechanism 300 includes a distribution pipe 305 horizontally distributed at the front and rear ends of the water pump motor part 100, and the air supply component 303 includes an active The plug cylinder 3031 is provided with a support foot at the bottom of the piston cylinder 3031. A partition plate 3032 is provided inside the piston cylinder 3031 to divide the internal space into an upper cavity and a lower cavity. A piston plate 3033 is horizontally provided in the upper cavity and the lower cavity. The piston plate 3033 fits the inner wall of the cavity. The buffer cooling mechanism 300 also includes a connecting rod 304 that passes through the upper and lower ends of the piston cylinder 3031 and is fixed to the surfaces of the two piston plates 3033 at both ends, and a connecting length is provided between the front and rear connecting rods 304. Plate 308, a driving cylinder 307 is provided on the lower surface of the connecting long plate 308, and a support can be provided between the driving cylinder 307 and the mounting surface to support the driving cylinder 307. The driving cylinder 307 is used to drive the connecting long plate 308 and the connecting rod 304 to move up and down. A refrigeration mesh plate 3034 is provided inside the upper cavity and the lower cavity, and two air inlet pipes 306 are provided between the outer surface of the piston cylinder 3031 and the distribution pipe 305. The lower ends of the two air inlet pipes 306 are respectively connected to the upper cavity and the lower cavity.

[0050] In summary, when the high-pressure pump is working, when the water pump motor part 100 vibrates downward, the arc-shaped buffer plate 301 moves downward due to the vibration, and the buffer seat 302 is gradually compressed and generates a reverse reset force, which can play a buffering and shock-absorbing role for the water pump motor part 100. When the water pump motor part 100 is working, the drive cylinder 307 works, and the internal piston rod retracts downward, driving the connecting long plate 308 and the connecting rod 304 to move downward, and the piston plate 3033 located in the upper cavity moves downward, and the space in the upper cavity becomes larger. The gas around the distribution pipe 305 is sucked into the upper cavity through the air holes, and the sucked gas is cooled by the refrigeration mesh plate 3034 in the upper cavity. At the same time, the piston plate 3033 in the lower cavity moves downward, The gas in the lower cavity is squeezed out and cooled again through the refrigeration mesh plate 3034 below. The cooled gas enters the distribution pipe 305 through the air inlet pipe 306 and is discharged through the air holes to act on the surface of the water pump motor part 100, cooling and dissipating the surface of the water pump motor part 100, thereby improving the service life of the high-pressure pump. When the piston rod inside the drive cylinder 307 extends upward, it drives the connecting rod 304 to move upward, and the piston plates 3033 in the upper cavity and the lower cavity move upward. At this time, the cooling gas in the upper cavity is squeezed out, and the lower cavity draws gas. The whole process is repeated, which can continuously cool and dissipate the surface of the water pump motor part 100, keep the water pump motor part 100 in a suitable temperature environment, and improve the heat dissipation effect of the water pump motor part 100.

[0051] Example 4

[0052] This embodiment is obtained by combining Example 1, Example 2 and Example 3.

[0053] During use, during the operation of the high-pressure pump, the temperature sensor 2063 is used to monitor the surface temperature of the water inlet 102 and the water outlet 103, and the monitoring data is transmitted to the DCS, so that the staff can monitor the working status of the high-pressure pump according to the temperature difference change. If the temperature sensor 2063 is damaged, the drive conversion component 204 can be used to change the position of the temperature sensor 2063 without suspending the operation of the high-pressure pump, so that the new temperature sensor 2063 can continue to monitor. At the same time, the shaft detection component 400 inside the water pump head 101 can be used to monitor the axial displacement change of the shaft. When the position variable reaches a certain value, it indicates that the wear of the balance disk has reached the limit, the on-site indicator light shows an abnormality, and transmits an alarm signal to the DCS. While the high-pressure pump is working, the buffer cooling mechanism 300 is used to buffer the bottom of the water pump motor part 100 and cool the surface of the water pump motor part 100 to dissipate heat, thereby improving the service life of the high-pressure pump.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
