Description

Technical Field

[0001] The present invention belongs to the technical field of testing devices, and particularly relates to a testing structure device for detecting the lift of a booster pump of a pure water machine. Background Art

[0002] The booster pump of a pure water machine is a device specifically used to increase the water pressure of a water purifier. As a core component of a pure water machine, the booster pump is one of the key components to ensure the normal operation of the pure water machine, and its importance is self-evident.

[0003] The booster pump drives the eccentric swing wheel to move through the rotation of the motor rotor, which is converted into the reciprocating motion of the diaphragm, thereby changing the volume of the water pump. A vacuum is formed at the inlet for water absorption, and pressure is formed at the outlet, continuously pumping out the water. The booster pump provides appropriate water pressure and water flow for the pure water machine to purify water through the reverse osmosis membrane, enabling the pure water machine to filter the water quality more quickly and thoroughly, and improving the filtering effect and water outlet speed of the water purifier;

[0004] The lift is an important performance parameter of the booster pump. Testing the lift can ensure that the performance of the booster pump meets the design requirements, thereby ensuring the normal operation of the pure water machine. Appropriate lift can ensure that when the pure water machine passes through filtering devices such as the reverse osmosis membrane, sufficient water pressure and water flow are obtained, thereby improving the filtering effect and water outlet speed. By testing the lift, problems existing in the booster pump, such as too high or too low lift, can be discovered in a timely manner, and corresponding measures can be taken for adjustment to avoid equipment damage or potential safety hazards. For pure water machine manufacturers, testing the lift of the booster pump can also be used as part of quality sampling inspection to ensure that the booster pumps of each pure water machine meet the quality standards. Testing the lift of the booster pump of a pure water machine is of great significance for ensuring the performance, filtering effect, equipment safety, and quality sampling inspection of the pure water machine;

[0005] However, there is currently no device on the market that can batch test the lift of booster pumps, so a testing structure device for detecting the lift of the booster pump of a pure water machine is needed to meet the requirements. Summary of the Invention

[0006] Aiming at the problems raised in the above background art, the purpose of the present invention is to provide a testing structure device for detecting the lift of a booster pump of a pure water machine.

[0007] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0008] A testing structure device for detecting the lift of a booster pump of a pure water machine, including a water tank, two support beams are installed on the water tank, a number of cross beams are equidistantly installed between the two support beams, a motor is installed on the cross beam, the output end of the motor is connected to a lead screw, and the lower end of the lead screw is rotatably installed on the inner bottom of the water tank;

[0009] A number of upright beams corresponding to each other in position are installed on the lower sides of the two support beams. The upright beams are provided with guide rails. A bottom plate is slidably installed between two adjacent upright beams through the guide rails. A straight plate is installed between the two bottom plates on the front and rear sides, and the straight plate is threadedly connected to the lead screw.

[0010] A vise is installed on the bottom plate. A hinge plate is installed on the vise. A double torsion spring is installed on the hinge shaft of the hinge plate. A temperature sensor is installed on the hinge plate. Ear plates are connected to the front and rear sides of the bottom plate, and detection mechanisms are installed on the ear plates on both the front and rear sides.

[0011] The detection mechanism includes a pipe seat. A detection pipe is fixedly installed on the pipe seat. Bent joints are rotatably installed at both the input end and the output end of the detection pipe. A reduced-diameter joint is installed on the bent joint. An instrument is installed on the pipe seat, and the input end of the instrument is placed in the detection pipe. A connecting water pipe placed in the water tank is connected to the end of the reduced-diameter joint.

[0012] Further limitation: Scale lines are engraved on the upright beams. With such a design, it is convenient to control the climbing height of the straight plate, and thus the use effect of the booster pump at this height can be intuitively seen.

[0013] Further limitation: There are at least three cross beams. With such a design, at least six booster pumps can be tested simultaneously, ensuring the test efficiency.

[0014] Further limitation: The cross-section of the guide rail is T-shaped. With such a design, it can form a snap-fit sliding match with the bottom plate, ensuring the smooth sliding of the bottom plate and preventing the position from shifting.

[0015] Further limitation: The half-circle rotation stroke of the vise handle controls the entire clamping range. With such a design, it is beneficial to quickly clamp and fix the booster pump, and at the same time, the half-circle stroke is not likely to interfere with the bottom plate.

[0016] Further limitation: A heat exchanger is installed in the water tank. With such a design, it is beneficial to control the water temperature and prevent the water temperature from affecting the head test result of the booster pump.

[0017] Further limitation: At least two of the ear plates are provided on one side of the bottom plate. With such a design, different instruments can be installed to adapt to different data of the booster pump for testing, such as installing a vacuum gauge, a pressure gauge or a flowmeter.

[0018] Further limitation: The hinge plate is a metal plate, and the contact end of the temperature sensor is a telescopic contact structure. With such a design, the metal plate is conducive to heat conduction, and thus conducive to the temperature sensing of the temperature sensor. The contact end of the temperature sensor being a telescopic contact structure prevents damage caused by hard collision and jitter.

[0019] Further limitation: A thermometer and a liquid level gauge are installed inside the water tank. With such a design, the thermometer is used to monitor the water temperature inside the water tank to prevent it from affecting the test of the booster pump, and the liquid level gauge is used to monitor the water level inside the water tank to prevent the water level from being too low and affecting the water absorption of the booster pump, thereby affecting the accuracy of the flow rate.

[0020] Further limitation: All the instruments are wireless transmission instruments, including but not limited to wireless pressure gauges, wireless vacuum gauges, and wireless flow meters. With such a design, the wiring of wires is reduced, and it also prevents the wires from being damaged by a humid environment. At the same time, the purpose of remote testing can be achieved.

[0021] Beneficial effects of adopting the present invention:

[0022] By adopting the structural design of the present invention, the simultaneous testing of multiple booster pumps can be achieved, and the head testing of booster pumps at different installation heights can also be achieved. Further, different numerical tests can be achieved by docking different instruments, expanding the scope of use;

[0023] By adopting the structural design of the present invention, the operating life of the booster pump in different operating environments, such as under the liquid and above the liquid, can also be tested, and a comparative experiment can be formed with the booster pump on the side, which is conducive to providing data support for the research and development of technology.

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0033] As Figures 1 to 4 shown, a test structure device for detecting the head of a booster pump of a pure water machine according to the present invention includes a water pool 1, two support beams 2 are installed on the water pool 1, a number of cross beams 3 are equidistantly installed between the two support beams 2, a motor 4 is installed on the cross beam 3, the output end of the motor 4 is connected with a lead screw 5, and the lower end of the lead screw 5 is rotatably installed on the inner bottom of the water pool 1;

[0034] A number of vertically arranged vertical beams 6 are installed on the lower sides of the two support beams 2, guide rails 7 are provided on the vertical beams 6, a base plate 8 is slidably installed between adjacent two vertical beams 6 through the guide rails 7, a straight plate 9 is installed between the two base plates 8 on the front and rear sides, and the straight plate 9 is threadedly connected to the lead screw 5;

[0035] A vice 10 is installed on the base plate 8, a hinge plate 11 is installed on the vice 10, a double torsion spring 12 is installed on the hinge shaft of the hinge plate 11, a temperature sensor 13 is installed on the hinge plate 11, ear plates 14 are connected to the front and rear sides of the base plate 8, and detection mechanisms 15 are installed on the ear plates 14 on both the front and rear sides;

[0036] The detection mechanism 15 includes a pipe seat 151, a detection pipe 152 is fixedly installed on the pipe seat 151, elbow joints 153 are rotatably installed at both the input end and the output end of the detection pipe 152, a reducing joint 154 is installed on the elbow joint 153, an instrument 155 is installed on the pipe seat 151, the input end of the instrument 155 is placed in the detection pipe 152, and the end of the reducing joint 154 is connected with a connecting water pipe placed in the water pool 1.

[0037] In this embodiment, when using a test structure device for detecting the head of the booster pump of a pure water machine, the motor 4 is controlled to operate, driving the screw rod 5 to rotate, thereby driving the straight plate 9 to lift, and further driving the bottom plate 8 connected to both sides and limited by the guide rail 7 to lift on the guide rail 7, so as to achieve the purpose of testing whether the head of the booster pump is affected in different height usage environments. The input end of the booster pump is connected to the output end of the monitoring mechanism 15 on the back side using a water pipe, and the output end of the booster pump is connected to the output end of the monitoring mechanism 15 on the front side using a water pipe. The settings of the elbow joint 153 and the reducing joint 154 in the detection mechanism 15 can adapt to the docking of water pipes with different pipe diameters and the booster pump, ensuring the use adaptability;

[0038] When the booster pump operates, the liquid in the water tank 1 is sucked in, passes through the detection mechanism 15 on the back side, flows through the pump body, and is discharged from the detection mechanism 15 on the front side and returns to the water tank 1. During this process, the instrument 155 on the back side and the instrument 155 on the front side perform counting, and then the head of the booster pump can be calculated using the formula with these two data. The formula used has been publicly disclosed in the prior art and is not difficult for those skilled in the relevant field to understand. Taking the instrument 155 on the back side and the instrument 155 on the front side as pressure gauges as an example, the formula includes but is not limited to:

[0039] [H = \frac{P}{\rho\times g}]

[0040] Where:

[0041] (H) is the head, usually in meters (m);

[0042] (P) is the pressure value shown on the pressure gauge, usually in pascals (Pa). Note that if the pressure gauge shows other units (such as bar, psi, etc.), it needs to be converted to pascals first;

[0043] (\rho) is the density of water, approximately (1000, kg / m³);

[0044] (g) is the acceleration due to gravity, approximately (9.81, m / s²);

[0045] Furthermore, in actual operation, some correction factors may need to be considered, such as pipeline friction loss, pressure loss at valves and joints, etc. These factors will affect the calculation result of the actual lift, so they need to be taken into account in precise calculations. Additionally, it is worth noting that the pressure gauge measures the relative pressure (i.e., the pressure relative to the atmospheric pressure). Therefore, when calculating the lift, if the pressure gauge shows the gauge pressure, this value can be directly used for calculation; if it shows the absolute pressure, the value of the atmospheric pressure (about 101325 Pa) needs to be subtracted before calculation;

[0046] It should be noted that the instruments 155 on both sides are not limited. If a vacuum gauge or a flowmeter is used, the corresponding formula will change, which is not difficult for those skilled in the relevant art to understand;

[0047] In summary, the detection of the booster pump in the present invention is simple, convenient and fast. Since multiple booster pumps can be tested simultaneously and the heights of each group are different, comparative data can also be obtained from the lift test between the two groups of booster pumps, which is beneficial for improvement. Further, the data of two booster pumps at the same height can also be used as comparative data, which can be used as data support for subsequent optimization and improvement of the booster pump;

[0048] Moreover, a temperature sensor 13 is installed in this structure, which can continuously monitor the temperature change inside the booster pump during operation due to continuous operation, and test its service life during high-intensity operation and the operating conditions changed due to temperature influence. And through the operation of the motor 4, the booster pump can be tested under the liquid level of the water tank 1, so as to compare and test the service life of the booster pump under the liquid level and above the liquid level. Further, by controlling the water temperature inside the water tank 1, the operating conditions of the booster pump in different water temperature usage environments can also be tested, achieving the purpose of obtaining various operating data of the booster pump, which is beneficial for research, optimization and improvement.

[0055] Preferably, the hinge plate 11 is a metal plate, and the contact end of the temperature sensor 13 is a telescopic contact structure. With such a design, the metal plate is conducive to heat conduction, and thus conducive to the temperature sensing of the temperature sensor 13.
