Description

Technical Field

[0001] The present invention relates to the technical field of booster pumps, and more particularly to a dual-inlet positive displacement turbine booster pump and a method for using the same. Background Art

[0002] The double-inlet positive displacement turbine booster pump is a specially designed pump commonly used in high-pressure fluid delivery systems, especially in situations where higher pressure boosting is required. As a liquid residual pressure energy recovery device, the turbine booster pump can effectively recover the liquid residual pressure energy in these industrial process flows. Turbine boosting technology converts the input mechanical energy into fluid pressure energy through the turbine impeller, and is suitable for high-flow, high-pressure applications.

[0014] Preferably: a method for using a dual-inlet positive displacement turbine booster pump, comprising the following steps: S1. Connect the liquid inlet to the outlet of the high-pressure liquid. After the high-pressure liquid enters the liquid inlet, the flow rate and flow velocity of the liquid passing through the liquid inlet are detected by a flow meter in the liquid inlet. When the flow velocity of the high-pressure liquid is detected to be too high, the motor drives the flap to rotate, so that the liquid is diverted through the diversion pipe and enters the first connecting pipe and the second connecting pipe respectively. S2.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by providing a regulating device, after the high-pressure liquid enters the liquid inlet, the flow rate and flow velocity of the liquid flowing through the liquid are detected by using a flow meter in the liquid inlet. When it is detected that the flow velocity of the high-pressure liquid is too high, the motor is used to drive the flap to rotate, so that the liquid is diverted through the diversion pipe and enters the first connecting pipe and the second connecting pipe respectively.

[0016] 2. In the present invention, by arranging a turbine device, when the liquid enters the turbine casing through the first connecting pipe and the second connecting pipe, it will be further diverted by the second curved plate in the first connecting pipe and the first curved plate in the second connecting pipe, so that the liquid in the fourth flow channel will flow to the third flow channel, and the liquid in the second flow channel will flow to the first flow channel, and finally enter the position of the turbine rotor in the turbine casing, thereby driving the turbine rotor to rotate. The diagonal arrangement of the first connecting pipe and the second connecting pipe effectively balances the radial force generated by the rotor, effectively reduces vibration and noise, and improves its service life.

[0017] 3. In the present invention, by providing a connecting device and a pressurizing device, before the entire equipment is put into operation, the oil drain plug is rotated and removed from the connecting shell, thereby releasing the waste lubricating oil generated in the previous working process in the waste oil tank. After discharging the waste oil, the oil drain plug is reinstalled, and the sealing cover is opened to add lubricating oil to the oil channel so that the lubricating oil evenly lubricates the side walls of the rotating shaft groove. As the turbine rotor rotates, the rotating shaft gradually transmits power to the pump impeller, and the pump impeller generates suction. The low-pressure liquid will enter the pump housing after being filtered by the filter screen. After the low-pressure liquid is pressurized by the rotation of the pump impeller, it is discharged from the position of the mounting plate. Lubricating oil can be added to the rotating shaft at the working front end, and self-lubrication of the rotating shaft side walls can be achieved as the rotating shaft rotates, preventing the rotating shaft from being damaged by long-term operation. The filter screen can effectively filter the low-pressure liquid before entering the equipment to prevent it from damaging the equipment, thereby further improving the service life of the equipment.

[0020] Example 1: Figure 1-Figure 5 As shown, the present invention provides a dual-inlet positive displacement turbine booster pump, comprising: The turbine device 1 is used to recycle high-pressure liquid, and includes a turbine shell 104. A first connecting pipe 106 is fixedly connected to one side wall of the turbine shell 104, and a second connecting pipe 108 is fixedly connected to the other side wall of the turbine shell 104. A second curved plate 1011 is fixedly connected to the inner wall of the first connecting pipe 106, and a first curved plate 109 is fixedly connected to the inner wall of the second connecting pipe 108. The side wall of the turbine shell 104 is also provided with an adjusting device for adjusting the flow direction of the liquid.

[0021] A turbine rotor 1010 is rotatably connected to the middle of the inner wall of the turbine housing 104, and a discharge port 101 is fixedly connected to the middle of the front end of the turbine housing 104. A second flow channel 1013 is provided at the top of the first curved plate 109, a third flow channel 1014 is provided at the bottom of the first curved plate 109, a first flow channel 1012 is provided at the top of the second curved plate 1011, and a fourth flow channel 1015 is provided at the bottom of the second curved plate 1011.

[0022] like Figure 4 As shown, it should be noted that a second curved plate 1011 is provided in the first connecting pipe 106, and a first curved plate 109 is provided in the second connecting pipe 108, and the first connecting pipe 106 and the second connecting pipe 108 are arranged diagonally. When the liquid enters the turbine casing 104, two symmetrical forces are generated on the turbine rotor 1010, thereby effectively offsetting the radial force, reducing the vibration and wear of the rotor, and making the unit run more smoothly. In addition, the use of the second curved plate 1011 and the first curved plate 109 can improve the uniformity of the overall equipment in accepting high-pressure liquid, thereby improving the energy recovery efficiency of the turbine, so that the liquid can more effectively impact the turbine rotor 1010, and the turbine rotor 1010 is subjected to two symmetrical moments at the same time, the equipment is easier to start, and its utilization rate is improved.

[0023] It should be noted that, by setting up the turbine device 1, when the liquid enters the turbine casing 104 through the first connecting pipe 106 and the second connecting pipe 108, it will be further diverted by the second curved plate 1011 in the first connecting pipe 106 and the first curved plate 109 in the second connecting pipe 108, so that the liquid in the fourth flow channel 1015 will flow to the third flow channel 1014, and the liquid in the second flow channel 1013 will flow to the first flow channel 1012, and finally enter the position of the turbine rotor 1010 in the turbine casing 104, thereby driving the turbine rotor 1010 to rotate. The diagonal arrangement of the first connecting pipe 106 and the second connecting pipe 108 effectively balances the radial force generated by the rotor, effectively reduces vibration and noise, and improves its service life.

[0024] The regulating device includes a liquid inlet 107, a flow meter 102 is provided on one side of the inner wall of the liquid inlet 107, a shunt tube 105 is fixedly connected to the other side of the top of the liquid inlet 107, a flap 1016 is rotatably connected to one side of the inner wall of the shunt tube 105, and a motor 103 is fixedly connected to the front end of the shunt tube 105.

[0025] It should be noted that, by setting up a regulating device, after the high-pressure liquid enters the liquid inlet 107, the flow rate and flow velocity of the liquid flowing through are detected by the flow meter 102 in the liquid inlet 107. When it is detected that the flow velocity of the high-pressure liquid is too high, the motor 103 is used to drive the flap 1016 to rotate, so that the liquid is diverted through the diversion pipe 105 and enters the first connecting pipe 106 and the second connecting pipe 108 respectively. The flow direction of the liquid can be regulated in real time according to the flow rate of the liquid, thereby effectively improving its working efficiency, reducing the energy loss generated by the liquid when entering the turbine, and enabling it to better drive the turbine rotor 1010 to rotate.

[0026] The first flow channel 1012 passes through the turbine housing 104 , the second flow channel 1013 communicates with the interior of the first flow channel 1012 , the third flow channel 1014 passes through the turbine housing 104 , the fourth flow channel 1015 communicates with the interior of the third flow channel 1014 , and the exhaust port 101 communicates with the interior of the turbine housing 104 .

[0027] The other end of the shunt tube 105 is connected to the interior of the first connecting tube 106, one end of the shunt tube 105 is connected to the interior of the liquid inlet 107, the liquid inlet 107 is connected to the interior of the second connecting tube 108, and the output end of the motor 103 passes through the shunt tube 105 and is fixedly connected to the middle of the flap 1016.

[0028] Working principle: The liquid inlet 107 is connected to the outlet of the high-pressure liquid. After the high-pressure liquid enters the liquid inlet 107, the flow rate and flow velocity of the liquid flowing through are detected by the flow meter 102 in the liquid inlet 107. When it is detected that the flow velocity of the high-pressure liquid is too high, the motor 103 is used to drive the flap 1016 to rotate, so that the liquid is diverted through the diversion pipe 105 and enters the first connecting pipe 106 and the second connecting pipe 108 respectively. When the liquid enters the turbine casing 104 through the first connecting pipe 106 and the second connecting pipe 108, it will be further diverted by the second curved plate 1011 in the first connecting pipe 106 and the first curved plate 109 in the second connecting pipe 108, so that the liquid in the fourth flow channel 1015 will flow to the third flow channel 1014, and the liquid in the second flow channel 1013 will flow to the first flow channel 1012, and finally enter the position of the turbine rotor 1010 in the turbine casing 104, thereby driving the turbine rotor 1010 to rotate.

[0029] Example 2: Figure 6-Figure 8 As shown, the present invention provides a double-inlet positive displacement turbine booster pump, including a connecting device 2 for protecting a rotating shaft, including a connecting shell 201, a rotating shaft groove 204 is opened in the middle of the inner wall of the connecting shell 201, and a boosting device 3 for boosting low-pressure liquid is provided at the rear end of the connecting shell 201. The boosting device 3 includes a pump shell 303, and a pump impeller 304 is rotatably connected to the middle of the inner wall of the pump shell 303.

[0030] It should be noted that, by setting the connecting device 2 and the boosting device 3, before the entire equipment is put into operation, the oil drain plug 202 is rotated and the oil drain plug 202 is removed from the connecting shell 201, thereby releasing the waste lubricating oil generated in the previous working process set in the waste oil tank 203. After the waste oil is discharged, the oil drain plug 202 is reinstalled, and the sealing cover 206 is opened, and lubricating oil is added to the oil channel 205, so that the lubricating oil evenly lubricates the side walls of the rotating shaft groove 204. Lubricating oil can be added to the rotating shaft at the working front end, and the side walls of the rotating shaft can be self-lubricated as the rotating shaft rotates, preventing the rotating shaft from being damaged due to long-term operation. The filter 302 can be used to effectively filter the low-pressure liquid before entering the equipment to prevent it from damaging the equipment, thereby further improving the service life of the equipment.

[0031] A sealing cover 206 is fixedly connected to the middle of the top of the connecting shell 201, an oil channel 205 is opened at the upper position inside the connecting shell 201, a waste oil tank 203 is opened on the front side of the inner wall of the connecting shell 201, and an oil drain plug 202 is provided in the middle of the bottom end of the connecting shell 201.

[0032] like Figure 8As shown, it should be noted that after the lubricating oil is replenished to the side wall of the rotating shaft through the oil channel 205, it lubricates the rotating shaft. However, the lubricating oil will gradually deteriorate and be contaminated during the rotation of the rotating shaft, and will be discharged into the waste oil tank 203 and accumulate at the bottom of the waste oil tank 203. Therefore, after a period of use, it is necessary to rotate the oil drain plug 202 to discharge the waste lubricating oil to increase the overall service life of the equipment.

[0033] A water inlet pipe 301 is fixedly connected to the middle of the rear end of the pump housing 303 , a filter screen 302 is fixedly connected to the other end of the water inlet pipe 301 , and a mounting plate 305 is fixedly connected to the opening of the side wall of the pump housing 303 .

[0034] A rotating shaft is rotatably connected to the inner wall of the rotating shaft groove 204. One end of the rotating shaft passes through the turbine casing 104 and is fixedly connected to the middle of the rear end of the turbine rotor 1010. The other end of the rotating shaft passes through the front end of the pump casing 303 and is fixedly connected to the middle of the front end of the pump impeller 304. The oil channel 205 passes through the side wall of the connecting casing 201 and is connected to the inside of the rotating shaft groove 204. The rotating shaft groove 204 is connected to the inside of the waste oil tank 203. The side wall of the oil drain plug 202 is threadedly connected to the middle of the bottom end of the connecting casing 201.

[0035] Working principle: Before the equipment as a whole is put into operation, rotate the drain plug 202 and remove the drain plug 202 from the connecting shell 201, thereby releasing the waste lubricating oil generated in the previous working process set in the waste oil tank 203. After draining the waste oil, reinstall the drain plug 202, open the sealing cover 206, and add lubricating oil to the oil channel 205 so that the lubricating oil evenly lubricates the side wall of the shaft groove 204. As the turbine rotor 1010 rotates, the shaft gradually transmits power to the pump impeller 304, and the pump impeller 304 generates suction. The low-pressure liquid will pass through the filter screen 302 and then enter the pump shell 303. The low-pressure liquid is pressurized by the rotation of the pump impeller 304 and then discharged from the position of the mounting plate 305.

[0036] Example 3: Figures 1-8 As shown, a method for using a dual-inlet positive displacement turbine booster pump comprises the following steps: S1. Connect the liquid inlet 107 to the outlet of the high-pressure liquid. After the high-pressure liquid enters the liquid inlet 107, the flow rate and flow velocity of the liquid passing through the liquid inlet 107 are detected by the flow meter 102 in the liquid inlet 107. When the flow velocity of the high-pressure liquid is detected to be too high, the motor 103 drives the flap 1016 to rotate, so that the liquid is diverted through the diversion pipe 105 and enters the first connecting pipe 106 and the second connecting pipe 108 respectively. S2. When the liquid enters the turbine housing 104 through the first connecting pipe 106 and the second connecting pipe 108, it is further divided by the second curved plate 1011 in the first connecting pipe 106 and the first curved plate 109 in the second connecting pipe 108. As a result, the liquid in the fourth flow channel 1015 flows into the third flow channel 1014, and the liquid in the second flow channel 1013 flows into the first flow channel 1012. Finally, the liquid enters the turbine rotor 1010 in the turbine housing 104, thereby driving the turbine rotor 1010 to rotate. S3. Before the entire device is put into operation, the oil drain plug 202 is rotated and removed from the connecting housing 201 to release the waste lubricating oil generated during the previous operation in the waste oil tank 203. After the waste oil is discharged, the oil drain plug 202 is reinstalled, and the sealing cover 206 is opened. Lubricating oil is added to the oil passage 205 so that the lubricating oil evenly lubricates the side walls of the rotating shaft groove 204. S4. As the turbine rotor 1010 rotates, the rotating shaft gradually transmits power to the pump impeller 304. The pump impeller 304 generates suction, and the low-pressure liquid passes through the filter 302 and enters the pump casing 303. The low-pressure liquid is pressurized by the rotation of the pump impeller 304 and is discharged from the position of the mounting plate 305.

S2, when the liquid enters the turbine housing (104) through the first connecting pipe (106) and the second connecting pipe (108), it is further divided by the second curved plate (1011) in the first connecting pipe (106) and the first curved plate (109) in the second connecting pipe (108), so that the liquid in the fourth flow channel (1015) flows to the third flow channel (1014), and the liquid in the second flow channel (1013) flows to the first flow channel (1012), and finally enters the position of the turbine rotor (1010) in the turbine housing (104), thereby driving the turbine rotor (1010) to rotate; S3. Before the entire device is put into operation, the oil drain plug (202) is rotated and removed from the connecting shell (201), thereby releasing the waste lubricating oil generated during the previous operation in the waste oil tank (203). After the waste oil is discharged, the oil drain plug (202) is reinstalled, and the sealing cover (206) is opened to add lubricating oil to the oil passage (205), so that the lubricating oil evenly lubricates the side wall of the shaft groove (204); S4. As the turbine rotor (1010) rotates, the rotating shaft gradually transmits power to the pump impeller (304). The pump impeller (304) generates suction, and the low-pressure liquid is filtered through the filter (302) and enters the pump casing (303). The low-pressure liquid is pressurized by the rotation of the pump impeller (304) and is discharged from the position of the mounting plate (305).
