Description

Technical Field

[0001] The invention relates to the technical field of high-pressure water jet pumps, and in particular to a servo-controlled hydraulically driven ultra-high-pressure water jet pump. Background Art

[0002] Ultra-high pressure fluid control pumps are widely used in many fields such as petroleum, chemical industry, metallurgy, electric power, water treatment, etc. When used with ultra-high pressure control valves, they can achieve automatic control and remote control, providing a solid power foundation for industrial development. In general, ultra-high pressure fluid control pumps are an indispensable and important equipment in the industrial field.

[0003] The existing ultra-high pressure water jet pump is driven by an ordinary motor. Since the motor speed is constant, the system pressure is a constant output.

[0004] Therefore, there are the following defects:

[0005] (1) Poor environmental protection and energy saving: For ordinary motor driven type, when there is no high-pressure jet output, the motor still outputs at full power, resulting in a waste of electric energy;

[0006] (2) Large noise and vibration: The operating characteristics of ordinary motors cause excessive noise and vibration of the pump body;

[0007] (3) High heat generation: Ordinary motors have hydraulic system characteristics and generate high heat;

[0008] (4) Low degree of automation control: non-closed-loop control type, manual operation is required to adjust the hydraulic pressure, and the output pressure control accuracy is low;

[0009] (5) Low controllability: The output pressure of the ordinary motor-type ultra-high pressure jet pump is set by the regulating valve on the hydraulic valve body, which is a manual adjustment type. Every time the output high-pressure water pressure is adjusted, the pump body protection cover needs to be opened and the regulating valve needs to be manually turned;

[0010] (6) Slow response time after pressure adjustment: It takes a certain amount of time to wait, or the machine needs to be shut down and restarted before the pressure of the output ultra-high pressure jet can reach the newly set pressure value;

[0011] (7) The life of wearing parts is relatively short: Due to the working characteristics of ordinary motor-type ultra-high pressure jet pumps, ultra-high pressure jets are output throughout the entire process even when there is no need to output ultra-high pressure jets, which greatly reduces the life of some high-pressure wearing parts.

[0012] (8) When low-pressure water flows through the filter, the filter screen inside the filter is often easily clogged. Once clogged, personnel are required to suspend the equipment and disassemble and clean the filter.

[0013] Therefore, it is necessary to provide a servo-controlled hydraulically driven ultra-high pressure water jet pump to solve the above technical problems. Summary of the invention

[0073] Embodiment 1: Figure 1 , Figure 2 , Figure 3 and Fig.13 As shown, it includes a support frame 28, a control interface is arranged outside the support frame 28 for controlling the whole, and also includes:

[0074] The supercharger 1 and the low-pressure water filter 9, the supercharger 1 is fixedly connected to the top of the support frame 28, the water outlet of the low-pressure water filter 9 is connected to the water inlet of the supercharger 1, the supercharger 1 is used to pressurize the low-pressure water, and the water outlet of the supercharger 1 is connected to the accumulator 2 for storing energy;

[0075] A hydraulic control mechanism, the hydraulic control mechanism is used to control the hydraulic oil circuit to drive the booster 1 to pressurize the liquid;

[0076] The hydraulic control mechanism includes a hydraulic oil tank 27 for storing hydraulic oil, a servo motor 3 and a hydraulic pump 4. The hydraulic oil tank 27, the servo motor 3 and the hydraulic pump 4 are all installed inside the support frame 28. After the servo motor 3 runs at a low speed, it drives the hydraulic pump 4 to transport the hydraulic oil from the hydraulic oil tank 27 to the hydraulic cylinder body 100, and the delivery pipes are respectively arranged on both sides of the piston 102 to drive the piston 102 to switch left and right. A hydraulic control valve 6 and a hydraulic valve block 5 are arranged on the outside of the hydraulic pump 4.

[0077] The supercharger 1 comprises:

[0078] A hydraulic cylinder 100, wherein a piston 102 is disposed inside the hydraulic cylinder 100, and punches 103 are slidably connected to both ends of the hydraulic cylinder 100, and both sides of the piston 102 are fixedly connected to the two punches 103 respectively;

[0079] Two booster cylinders 101 are respectively disposed at two ends of the hydraulic cylinder body 100 , and two punching heads 103 respectively extend into the inside of the booster cylinders 101 to pressurize the low-pressure water inside the booster cylinders 101 .

[0080] A compressed air interface 20 , a platform drain port 21 , a low-pressure water inlet 22 , a cooling water inlet 23 , a cooling water outlet 24 and a drain port 25 are arranged on the outside of the support frame 28 .

[0081] The support frame 28 is also provided with a hydraulic pressure gauge 7, a low-pressure water inlet pressure gauge 8, a water inlet pressure detector 10, a low-pressure water inlet valve 11, a low-pressure sensor, and a high-pressure sensor 17 for detecting water.

[0082] During specific implementation, low-pressure water is introduced through the low-pressure water inlet 22, and the pressure of the low-pressure water is detected by the water inlet pressure detector 10 to the servo motor 3. If the pressure does not reach the set value, an alarm is given; the low-pressure water is then filtered by the low-pressure water filter 9, and then transported to the two booster cylinders 101 in the booster 1 through the delivery pipeline, and the servo motor 3 is started by controlling the servo controller; after the servo motor 3 runs at a low speed, it drives the hydraulic pump 4 to transport the hydraulic oil from the hydraulic oil tank 27 to the booster cylinder 101 in the booster 1; the control system controls the hydraulic oil through the hydraulic control valve The hydraulic oil circuit is used to drive the piston 102 in the hydraulic cylinder 100 to switch left and right; when the high-pressure sensor 17 detects that the pressure reaches the set value in real time, the whole system stops pressurizing; through the external control interface HMI, press "low-high pressure switch", then the control system controls the servo controller again to make the servo motor 3 run at high speed; when the high-pressure sensor 17 detects that the pressure reaches the set high-pressure value in real time, the whole system stops pressurizing; at this time, the servo motor 3 runs at idle speed; after the high-pressure water is discharged, when it reaches the set high-pressure compensation pressure value, the servo motor 3 runs again, Until the pressure reaches the set high pressure value, the whole system stops pressurizing, and the servo motor 3 runs at idle speed again; the low-pressure sensor detects the real-time pressure of the driving hydraulic oil; the high-pressure sensor 17 detects the real-time pressure of the high-pressure water generated by the supercharger 1; the low and high-pressure sensors form a closed-loop control; when the high-pressure pump is not in use, it is necessary to switch from "high pressure" to "low pressure", and then press "stop" to stop the servo motor 3; by controlling the pressure relief valve to close the high-pressure water outlet and open the drain port, the high-pressure water in the high-pressure pump is discharged to relieve the pressure, thereby achieving servo control. When ultra-high-pressure water jets need to be generated, It only runs according to the set high-pressure pressure value, and runs at idle speed when not needed, which greatly reduces the energy consumption during standby. The ultra-high pressure water jet control is a closed-loop PID control, and the output pressure control accuracy is precise; the ultra-high pressure water jet output pressure response time is fast: the working state of the servo motor can be quickly adjusted; this control system is a closed-loop control, which can achieve precise pressure and flow control of the ultra-high pressure jet; the working characteristics of the servo motor type ultra-high pressure jet pump are that when the ultra-high pressure jet does not need to be output, the servo motor idle speed will not generate ultra-high pressure water jets, and the life of high-pressure wearing parts is greatly improved.

[0083] Embodiment 2: Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the low-pressure water filter 9 is installed inside the support frame 28, and a rotating disk 903 is provided inside the low-pressure water filter 9.

[0090] During specific implementation, when low-pressure water passes through the water inlet cover 9040, through the filter screen 9031 on the rotating disk 903, and is discharged through the water outlet cover 9041, the low-pressure water is filtered. The filter screen 9031 will be blocked by the filtered matter during long-term filtration. When the filtered matter causes blockage, water will gather on the upper part of the filter screen 9031. At this time, the float plate 9071 will rise due to the buoyancy of the water, and the contact rod 9072 fixedly connected to the float plate 9071 will touch the touch switch 9073, thereby starting the switching component and switching the other filter screen 9031 between the water inlet cover 9040 and the water outlet cover 9041, thereby ensuring the filtration of the low-pressure water and avoiding pausing the equipment.

[0107] The second magnet ring 9084 rotatably connected to the interior of the upper movable plate 9062 is magnetically attracted to the first cleaning frame 9055 , and a second cleaning frame 9083 for cleaning the filter screen 9031 is fixedly connected to the interior of the first cleaning ring 9054 .

[0108] In specific implementation, when the rotating disk 903 is switched, a fixed ring plate 9061 is provided inside the lower cleaning frame 906, and the connecting rod 9068 on the push plate 9063 drives the upper movable plate 9062 to keep in contact with the bottom of the filter screen 9031 through the elastic effect of the spring 9064, so that the second cleaning frame 9083 inside the upper movable plate 9062 contacts the lower part of the filter screen 9031, and the electromagnet ring 9056 in the upper cleaning member is energized. When the electromagnet ring 9056 is energized, the electromagnet ring 9056 drives the second magnet ring 9084 to rotate through magnetic attraction, and then the second cleaning frame 9083 continuously rotates and cleans the bottom of the filter screen 9031, so as to cooperate with the upper cleaning member to clean, thereby improving the cleaning effect;

[0109] In addition, a first magnet ring 9066 can be provided on the outer side of the upper movable plate 9062. When the electromagnet ring 9056 is energized, the direction of the current changes, and the magnetism of the electromagnet ring 9056 also changes. At this time, the upper movable plate 9062 is squeezed downward by the magnetic repulsion, and the second cleaning frame 9083 is separated from the filter screen 9031. The upper movable plate 9062 is continuously raised and lowered by the continuous change of the magnetism of the electromagnet ring 9056, so that the second cleaning frame 9083 continuously pushes out the lower part of the filter screen 9031, thereby avoiding the filter being stuck inside the filter screen 9031 during cleaning, thereby improving the cleaning effect.

[0114] In a specific implementation, the foldable cover 9067 is fixedly connected between the fixed ring plate 9061 and the push plate 9063. When the upper movable plate 9062 drives the push plate 9063 to rise and fall through the connecting rod 9068, when the push plate 9063 is in an ascending state, the push plate 9063 squeezes the foldable cover 9067, and the water inside the foldable cover 9067 is transported to the inside of the water outlet frame 908 through the liquid outlet pipe, and sprayed out through multiple nozzles 9082. When the push plate 9063 descends, the foldable cover 9067 sucks the liquid into the foldable cover 9067 through the liquid suction pipe. The filter net 9031 is continuously impacted from bottom to top by the spraying and suction of the liquid, and the filter net 9031 is fully cleaned in cooperation with the second cleaning rack 9083 and the first cleaning rack 9055.

[0115] When the filtrate needs to be discharged, cleaning water is introduced through the flushing pipe 9069, passes through the filter screen 9031 and enters the rotating ring 9051, and is finally discharged through the drain pipe 9050, thereby cleaning the filtrate on the filter screen 9031.
