Abstract
Description
Technical Field
[0001] This invention relates to the field of plunger pump technology, and more particularly to a plunger pump cleaning device. Background Technology
[0002] A piston pump is an important component of a hydraulic system. It achieves oil suction and pressure by the reciprocating motion of a piston within a cylinder, which changes the volume of the sealed working chamber. Piston pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow rate adjustment.
[0003] The reverse osmosis reducing agent dosing system is used to add reducing agents to the reverse osmosis feed water to neutralize oxidizing substances and protect the reverse osmosis membrane. It uses bagged reducing agents for dissolution and preparation. During long-term operation, impurities and crystals introduced during preparation can clog the plunger pump, causing a decrease in pump output or even preventing dosing. Air entering the plunger pump during inlet filter cleaning can also lead to no dosing. However, plunger pump clogging and air ingress are just two common causes of no dosing. These two causes are not easily visually checked during operation and require manual cleaning of the pump inlet and outlet, which is time-consuming and labor-intensive.

[0031] To more clearly illustrate the technical solutions in this invention, specific embodiments are described below.
[0032] Example
[0033] like Figure 1-3 As shown, this embodiment provides a plunger pump cleaning device, which is mainly used on a plunger pump 11. It includes a water supply component installed at the inlet of the plunger pump 11, a cleaning component installed inside the plunger pump 11, and a water outlet component installed at the outlet of the plunger pump 11. The cleaning device provided in this embodiment cleans the plunger pump 11 according to the degree of blockage. When the blockage is minor, the water supply component flushes the plunger pump 11 with water, and the flushing water is discharged through the water outlet component. When the blockage is severe, the cleaning component cleans the inside of the plunger pump 11, and the water supply component flushes the plunger pump 11 with water. The two components work together to clean the plunger pump 11.
[0034] In this embodiment, in order to achieve a good cleaning effect, the cleaning assembly includes a cleaning column, which is connected to the water supply assembly. During use, the cleaning column enters the interior of the cleaning column to clean the blockages (impurities or crystals) inside the cleaning column, thereby preventing the plunger column from becoming clogged.
[0035] The cleaning column comprises an inner column 3 and an outer column 9. The inner column 3 is fixedly connected to one end of the outer column 9. Specifically, the inner column 3 and the outer column 9 are fixedly connected at the ends near the water supply assembly. In this embodiment, the inner column 3 is made of a soft material, such as a PPH pipe or plastic tube. The outer column 9 is made of an elastic material, such as rubber or polyurethane. Simultaneously, the inner column 3 is connected to the water supply assembly, which supplies water to the inner column 3. Upon receiving water, the inner column 3 begins to extend, gradually extending from its connection with the water supply assembly and slowly entering the plunger pump 11 until it extends out from the outlet of the plunger pump 11. Then, it supplies water to the outer column 9 for cleaning.
[0036] To ensure that the inner column 3 can extend smoothly from the plunger pump 11, in this embodiment, an opening block 6 is provided at the end of the inner column 3. The opening block 6 is located at the end of the inner column 3 away from the water supply component. A rangefinder is provided on the inner column 3, and the rangefinder is correspondingly provided with the opening block 6. The rangefinder can detect the path of the opening block 6 to prevent the opening block 6 from damaging the internal components of the plunger pump 11.
[0037] After the inner column 3 is extended, the opening block 6 is connected to the supporting block 7, and the supporting block 7 is connected to the water outlet assembly. The top of the opening block 6 is provided with a support column 61 and a plug column 62. The plug column 62 is disposed within the support column 61 and slides along the support column 61. A baffle is provided at the end of the plug column 62 near the inner column 3, and the diameter of the baffle is smaller than the inner diameter of the inner column 3. The end of the plug column 62 away from the inner column 3 extends out of the support column 61. A water passage hole 63 is provided on the support column 61, and the water passage hole 63 allows the water outlet assembly to pass through. The inner column 3 is connected to the outer column 9. The connection between the support column 61 and the outer column 9 encloses the water passage 63 inside the outer column 9. The connection between the inner column 3 and the support column 61 does not include the water passage 63 inside the inner column 3. When the opening block 6 is connected to the support block 7, the plug column 62 extends into the support column 61 due to a portion of it. The baffle on the plug column 62 separates from the support column 61, and the water in the inner column 3 flows into the outer column 9 through the water passage 63, allowing the outer column 9 to be flushed.
[0038] Of course, multiple adjusting holes 5 are provided on the outer circumferential surface of the opening block 6. The adjusting holes 5 are evenly distributed on the outer circumferential surface of the opening block 6. The adjusting holes 5 are connected to the adjusting pipes 4. The adjusting pipes 4 are connected to the inner column 3. In this embodiment, four adjusting holes 5 are provided during use, and four adjusting pipes 4 are also provided. The adjusting pipes 4 are connected to the inner column 3, the outer column 9 and the water supply assembly through a multi-way valve 12.
[0039] To achieve a good cleaning effect, several flushing holes 10 are provided on the outer column 9. The flushing holes 10 can flush the inside of the plunger pump 11 to achieve a good cleaning effect. Of course, in this embodiment, the flushing holes 10 are set on the outer column 9 to connect the inside of the outer column 9 with the outside of the outer column 9. After the inner column 3 extends, the connection switch between the inner column 3 and the outer column 9 on the multi-way valve 12 is opened, and water flows through the outer column 9. The water flows out from the flushing holes 10 to clean the inside of the plunger pump 11. To better describe the positional relationship between the outer column 9 and the flushing holes 10, it is assumed that the outer column 9 is placed vertically, and the flushing holes 10 are arranged in multiple rows from top to bottom. The flushing holes 10 in each row are evenly arranged on the outer circumference of the outer column 9. Of course, the flushing holes 10 can be set as circular, or the circular flushing holes 10 can be set with teeth to increase the impact force of the flushing holes 10 and improve the cleaning effect.
[0040] In this embodiment, the water supply assembly includes a water supply pipe 1, which is connected to a multi-way valve 12. The water supply pipe 1 is connected to the inlet of the plunger pump 11 through the multi-way valve 12. The water supply pipe 1 is also connected to a water supply valve 2. A through hole is provided at the center of the water supply valve 2. The inner column 3 and the outer column 9 are connected to the inlet of the plunger pump 11 through the through hole. The water supply valve 2 is provided with a plurality of water supply holes 21. A baffle plate 22 is provided on the water supply holes 21. The baffle plate 22 is inclined and tilted towards the outer circumference of the water supply valve 2.
[0041] The water outlet assembly is provided with a water outlet pipe 8, and the support block 7 is provided on the water outlet pipe 8. The water outlet pipe 8 is connected to the water outlet of the plunger pump 11 through a three-way valve 13. The three-way valve 13 is also connected to an air blowing pipe. The water outlet pipe 8 is connected to a collection tray, and the collection tray collects the blockages in the plunger pump 11.
[0042] Of course, the present invention also includes a controller to control the cleaning device. The controller controls the opening and closing of the multi-way valve 12 and the three-way valve 13 to achieve a better cleaning effect.
[0043] To further enhance understanding of the present invention, the following method of using the plunger pump cleaning device is provided, which includes the following steps:
[0044] (1) Installation:
[0045] First, connect the water inlet pipe 1 to the multi-way valve 12. Then, connect the four torque adjustment pipes 4 and the inner column 3 to the multi-way valve 12 in sequence. Next, install the outer column 9, the torque adjustment pipe 4 located inside the outer column 9, the inner column 3, and the opening block 6 into the through hole on the water inlet valve 2. Then, connect the water inlet valve 2 to the inlet of the plunger pump 11. Next, connect the water outlet pipe 8, the air blowing pipe, and the outlet of the plunger pump 11 to the three-way valve 13 in sequence. Finally, connect the three-way valve 13, the multi-way valve 12, and the controller. The installation is now complete.
[0046] (2) Debugging:
[0047] After installation, the controller controls the multi-way valve 12 to open the switch of the inner column 3, water flows through the inner column 3, the inner column 3 extends along the inside of the plunger pump 11 until the inner column 3 extends out of the plunger pump 11, the rangefinder detects the distance when the opening block 6 extends, and sends the detected data to the controller, the controller records the extension path of the opening block 6 installed at the end of the inner column 3 when there is no blockage inside the plunger pump 11.
[0048] (3) Usage:
[0049] A: Gas enters the plunger pump 11:
[0050] When the plunger pump 11 is blocked or the flow rate is low, firstly, the operation of the plunger pump 11 is suspended. Then, the controller opens the three-way valve 13, and the interior of the plunger pump 11 is connected to the air blowing pipe to exhaust the air. After the exhaust is completed, if the plunger pump 11 can be used again (no longer blocked or the flow rate is restored), the fault is eliminated and the plunger pump 11 can continue to be used. Otherwise, proceed to step B.
[0051] B: When the plunger pump 11 is blocked or the flow rate is low, firstly, the controller controls the multi-way valve 12 to open the switch between the water inlet pipe and the water supply valve 2, the water supply valve 2 is supplied with water, and the controller controls the water flow rate of the water supply valve 2. By adjusting the flow rate of the water supply valve 2, the plunger pump 11 is flushed. If the plunger pump 11 can be used, the fault is eliminated, and the plunger pump 11 continues to be used.
[0052] If the flow rate of the plunger pump 11 still does not meet the usage standard, the controller controls the multi-way valve 12 to open the switch between the water inlet pipe and the inner column 3, water flows through the inner column 3, and the inner column 3 gradually extends into the interior of the plunger pump 11. At the same time, the rangefinder detects the path of the opening block 6 at the top of the inner column 3. The rangefinder transmits the detected data to the controller. The controller compares the real-time path of the opening block 6 with the path recorded in (2). When a path deviation is detected, the controller controls the multi-way valve 12 to open the switch between the water inlet pipe and the torque adjustment pipe 4, selects the appropriate torque adjustment hole 5, and water flows through the torque adjustment hole 5 to generate an impact force on the opening block 6, adjusting the extension direction of the opening block 6. Of course, the water flow rate of the torque adjustment hole 5 is relatively slow to prevent the impact force received by the opening block 6 from being too large and causing damage to the interior of the plunger pump 11.
[0053] After the inner column 3 extends, the opening block 6 on the inner column 3 overlaps with the support block 7, the baffle on the plug 62 on the opening block 6 separates from the support column 61, the inner column 3 and the outer column 9 are connected through the water passage 63, the water in the inner column 3 flows into the outer column 9 and flows out from the flushing hole 10 opened on the outer column 9 to flush the inside of the plunger pump 11.
[0054] When the flow rate of the plunger pump 11 is restored, the water in the inner column 3 flows out from the outer column 9. At the same time, the air pump connected to the multi-way valve 12 inflates the inner column 3, completely removing the water from the inner column 3 and the outer column 9. The perforation block 6 separates from the support block 7 (of course, to ensure that the water in the inner column 3 can flow out completely, the support block 7 can be set as an electromagnet and the perforation block 6 as a magnet. When the water flows out, the electromagnet is de-energized, and the support block 7 separates from the perforation block 6). The plug plate on the plug column 62 re-engages with the support column 61, and the air pump pumps air out of the inner column 3, retracting the inner column 3 (since the outer column 9 is made of elastic material, when the outer column 9 separates from the inner column 3, the outer column 9 will attract the inner column 3 due to its elasticity). The plunger pump 11 is cleaned and resumes use.
[0055] Of course, the blockage on the plunger pump 11 will eventually flow into the collection tray, and the blockage on the collection tray needs to be cleaned after use.
[0056] This invention cleans the inside of the plunger pump 11 by setting an inner column 3 and an outer column 9, and at the same time, it cleans the inside of the plunger column by setting an outlet pipe 8. The two work together to avoid the flow rate reduction caused by the plunger pump 11 not being cleaned properly, thus avoiding the impact on the project progress.
[0057] Finally, it is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the principles and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
