The magnetic suspension blower test is one of the intermediate steps from the production to the production of the magnetic suspension blower, and the test result relates to whether the magnetic suspension blower can normally be on line, whether the performance of the magnetic suspension blower reaches the standard, and whether the product is qualified. The existing test flow is divided into a single machine test and a complete machine test, wherein the single machine test is firstly carried out on the magnetic suspension blower, then the complete machine test is carried out on the magnetic suspension blower, and the complete machine test is assisted and standardized by utilizing the data of the single machine test so as to determine the working state of the magnetic suspension blower test. The method for separating the test is time-consuming and labor-consuming, and because the test environment and the test condition of the single machine test are different from those of the whole machine test, errors exist between the data of the single machine test and the data of the whole machine test, and the performance judgment and the working state judgment of the magnetic suspension blower are influenced.
In order to solve the above problems, the present disclosure provides a testing method of a magnetic levitation blower, which adjusts the rotation speed of the magnetic levitation blower to a preset rotation speed; adjusting the opening of a valve of an air outlet pipeline, and determining the maximum flow and the minimum flow; determining a performance test point based on the maximum flow and the minimum flow; recording preset parameters of the performance test points; and determining a performance curve of the magnetic suspension blower at a preset rotating speed based on the preset parameters. The testing method disclosed by the invention omits the flow of single machine testing, directly utilizes the data obtained by the whole machine testing to determine the performance curve, judges the working state of the magnetic suspension blower, reduces the testing time, reduces the manpower and material resources required to be consumed in the testing process, eliminates the data errors caused by different single machine testing environments and whole machine testing environments, and improves the accuracy of data display and running state judgment of the magnetic suspension blower.
The exemplary embodiment of the disclosure provides a test device of a magnetic suspension blower, as shown in fig. 4, the magnetic suspension blower 1 is placed in an electric cabinet 4, the electric cabinet 4 comprises an air outlet pipeline 2, an air inlet pipeline 3, an electric element 5 and a base 6, the magnetic suspension blower 1 is placed on the base 6, the air outlet pipeline 2 is communicated with an air outlet of the magnetic suspension blower 1, the air inlet pipeline 3 is communicated with an air inlet of the magnetic suspension blower 1, the electric element 5 refers to an element assembly of a level device, an amplifier, an impedance, a sensor, a controller and the like, and a control system is formed by various electric elements to realize the test of the magnetic suspension blower. The magnetic suspension blower in the present disclosure is placed in an electric cabinet for testing and data acquisition, i.e. a complete machine testing method is adopted.
According to a first exemplary embodiment, as shown in fig. 1, a testing method of a magnetic levitation blower shown in the present disclosure is implemented based on the testing apparatus of a magnetic levitation blower above, and includes:
s101, adjusting the rotating speed of a magnetic suspension blower to a preset rotating speed;
s102, adjusting the valve opening of an air outlet pipeline, and determining the maximum flow and the minimum flow;
s103, determining a performance test point based on the maximum flow and the minimum flow;
s104, recording preset parameters of the performance test points;
s105, determining a performance curve of the magnetic suspension blower at a preset rotating speed based on preset parameters.
In step S101, the electric cabinet provides an adaptive power supply for the magnetic suspension blower (hereinafter referred to as blower), and ensures that the blower is communicated with the air outlet pipeline and the air inlet pipeline, so that an air source required by the blower during operation can be provided. The control system starts the fan to carry out suspension debugging on the fan, and determines that the fan can normally operate through a suspension state, a waveform state, magnetic force and the like, and then the fan is tested. The control system adjusts the rotating speed of the fan to a preset rotating speed, and the suspension state is required to be paid attention to at any time while the rotating speed of the fan is adjusted so as to finish the performance test of the fan at the preset rotating speed. The preset rotating speed can be set according to the performance and the model of the fan and comprises a plurality of rotating speed parameters. When performance testing is performed, in order to facilitate testing and recording, the rotation speed of the fan can be adjusted according to the sequence of a plurality of rotation speed parameters from low to high or from high to low, and the performance curve of the fan under each rotation speed parameter is determined.
In step S102, a valve of the air outlet pipeline is disposed at an interface connected with the electric cabinet, and the opening of the valve affects the flow of the fan. The flow unit of the fan is cubic meter/minute (m 3 The flow of the fan is positively correlated with the opening of the valve, namely the larger the opening of the valve is, the larger the flow of the fan is; the smaller the opening of the valve is, the smaller the flow of the fan is, so that the maximum flow and the minimum flow of the fan can be determined by adjusting the opening of the valve of the air outlet pipeline.
It should be noted that the minimum flow rate of the blower is not determined based on the valve being in a completely closed state. Because the fan can be in a surge state when the opening degree of the valve is too small, the fan can be in a surge state to cause strong mechanical vibration and seriously damage parts of the fan, and therefore, the valve can not be completely closed in the conventional use process. Therefore, during the test, the determination of the minimum flow can be determined according to the position of the fan in the surge state.
In step S103, the control system may determine a plurality of performance test points within a range corresponding to the maximum flow rate and the minimum flow rate, and perform data acquisition. The number of the performance test points can be set based on the test precision requirement of the fan, and if the higher precision test of the fan needs to be completed, more test points can be set to acquire more data of preset parameters; if the lower precision test of the fan needs to be completed, a smaller number of test points can be set. In addition, the number of test points may be set directly by the control system. For example, the number of test points is 5, and the maximum flow is determined to be 60m 3 /min, determining the minimum flow to be 10m 3 In/min, in [10, 60]In the range, the working state of the fans corresponding to the 5 flow values is determined as the test points, for example, the fan flow of each test point in the 5 test points can be determined to be 10m 3 /min、20m 3 /min、35m 3 /min、50m 3 /min、60m 3 And/min.
In step S104, the control system adjusts the opening of the valve of the air outlet pipeline, so that the fan has a flow corresponding to the test point, and records the preset parameters at the test point. The preset parameters comprise at least one of the flow rate of the magnetic suspension blower, the air outlet pressure of the magnetic suspension blower, the operation power of the magnetic suspension blower and the operation efficiency of the magnetic suspension blower. Wherein, the fan is built-in to have the flow instrument, and control system can obtain the flow of fan through the communication connection with flow instrument. The air outlet pressure is inversely related to the flow, namely, the larger the flow is, the smaller the air outlet pressure is, the air outlet pressure can be collected by a pressure sensor arranged on an air outlet pipeline, and the control system is in communication connection with the pressure sensor so as to obtain the value of the air outlet pressure under each flow. In addition, the working state of the fan can be influenced by the temperature, the air pressure, the humidity and the like of the environment, so that the parameters of the performance test points, such as the corresponding environment temperature, the environment air pressure, the environment humidity and the like, can be recorded.
In step S105, the control system draws a performance curve of the fan at the preset rotation speed based on the values of the preset parameters, and because there are a plurality of rotation speed parameters for the preset rotation speed and a plurality of preset parameters, a plurality of performance curves referring to different parameter relationships for the plurality of rotation speed parameters can be drawn. The performance curve comprises at least one of a flow-air outlet pressure curve of the magnetic suspension blower, a flow-operation power curve of the magnetic suspension blower and a flow-operation efficiency curve of the magnetic suspension blower. For example, the preset rotation speed includes 5 rotation speed parameters, the preset parameters include flow, air outlet pressure and operation power of the fan, and then performance curves under the 5 rotation speed parameters need to be drawn, wherein under the same rotation speed parameters, two curves of flow-air outlet pressure of the fan and flow-operation power of the fan can be drawn, and in order to facilitate reference comparison of performance of the fan, the two curves can be drawn in the same graph. The determined performance curve is used for testing products of other fans with the same model, and if the fan has great difference with parameters indicated by the performance curve under the same working condition, for example, the running power of the fan and the running power corresponding to the performance curve are different by 40kw under the same rotating speed and flow, the performance of the fan is not up to standard, and the products are not up to standard.
In the method, the magnetic suspension blower is arranged in the electric cabinet, a single machine testing process is omitted, the performance curve is determined by directly utilizing data obtained by the whole machine testing, the working state of the magnetic suspension blower is judged, the testing time is shortened, the manpower and material resources required in the testing process are reduced, the data errors caused by different single machine testing environments and whole machine testing environments are eliminated, and the accuracy of data display and running state judgment of the magnetic suspension blower is improved.
According to a second exemplary embodiment, as shown in fig. 2, the testing method of the magnetic levitation blower in the present embodiment includes:
s201, adjusting the rotating speed of the magnetic suspension blower to a preset rotating speed;
s202, adjusting a valve of an air outlet pipeline to be in a full-open state, and determining the flow of the magnetic suspension blower to be the maximum flow when the valve is in the full-open state;
s203, adjusting the opening of a valve of the air outlet pipeline to enable the magnetic suspension blower to be in a surge state, and determining the flow of the magnetic suspension blower to be the minimum flow when the magnetic suspension blower is in the surge state;
s204, determining a performance test range based on the maximum flow and the minimum flow;
s205, determining a performance test point based on the performance test range;
s206, recording preset parameters of the performance test points;
s207, determining a performance curve of the magnetic suspension blower at a preset rotating speed based on preset parameters.
The steps S201, S206, S207 are the same as the implementation of the steps S101, S104, S105 in the above embodiment, and will not be described herein.
In step S202, the control system adjusts the valve of the air outlet pipe to be in a full-open state, and the flow rate of the fan is used as the maximum flow rate in the test process when the valve is in the full-open state because the flow rate is positively correlated with the opening degree of the valve.
In step S203, the control system adjusts the valve of the air outlet pipe to make the fan in a surge state. The control system judges whether the fan is in a surge state according to the outlet pressure of the fan. When the opening of the valve is regulated, and the pressure of the fan is not changed rapidly, the fan is considered to be in a surge state, and the flow of the fan under the current opening of the valve is the minimum flow.
In step S204, the maximum flow rate is the maximum value of the performance test range, and the minimum flow rate is the minimum value of the performance test range, so as to determine the performance test range. For example, the maximum flow is 70m 3 /min, determining the minimum flow to be 15m 3 And/min, determining the performance test range to be [15, 70]。
In step S205, since the maximum flow rate is determined in the state where the valve opening is fully opened and the minimum flow rate is determined in the state where the fan is in surge, the operating states of the fan at the position of the maximum flow rate and the position of the minimum flow rate are representative, and thus the performance test points include a first test point indicating the position of the maximum flow rate of the fan and a second test point indicating the position of the minimum flow rate of the fan. The control system determines the rest performance test points in the performance test range except the first test point and the second test point, wherein each performance test point can be the same numerical value interval or different numerical value intervals.
In some embodiments, step S205 determines a plurality of performance test points based on the performance test range, including:
equally dividing the performance test range according to a preset interval;
and determining a plurality of dividing nodes of the performance test range as performance test points.
In order to improve the smoothness of the performance curve, the control system equally divides the performance test range according to preset intervals, and the divided nodes are used as performance test points. The number of the preset intervals, the number of the performance test points and the size of the performance test range are determined, and if the performance test range is large, the number of the performance test points is small, larger preset intervals can be set; if the performance test range is small and the number of the performance test points is large, a smaller preset interval can be set. For example, the maximum flow is 10m 3 /min, determining the minimum flow to be 90m 3 /min, determining the performance test range as [10, 90 ]]Setting 5 performance test points, wherein the first test point is that the fan flow is 10m 3 The working state corresponding to/min is that the flow of the fan is 90m at the second test point 3 The corresponding operating state/min, the control system is also required to be within the performance test range [10, 90 ]]The other 3 performance test points except the two endpoints are determined, the preset interval can be set to 20, the divided nodes are 30, 50 and 70, namely, the other 3 performance test points are respectively fan flow of 30m 3 /min、50m 3 /min and 70m 3 And/min.
In the method, the performance test points comprise working states of the fans in maximum flow and minimum flow, so that the finally determined performance curve is more specific and comprehensive, the performances of the fans in various working states can be reflected, and the accuracy of data is improved. Because each performance test point is determined from the performance test range according to the preset interval, the smoothness of the performance curve at each rotating speed is improved.
According to a third exemplary embodiment, as shown in fig. 3, a testing method of a magnetic levitation blower in the present embodiment includes:
s301, adjusting the rotating speed of the magnetic suspension blower to a preset rotating speed;
s302, adjusting the valve opening of the air outlet pipeline;
s303, judging whether the magnetic suspension blower is in a state with maximum operation efficiency, and if the magnetic suspension blower is in the state with maximum operation efficiency, executing a step S304; if the magnetic suspension blower is not in the state of maximum operation efficiency, executing step S301;
s304, recording preset parameters of the magnetic suspension blower in a state of maximum operation efficiency;
s305, adjusting a valve of an air outlet pipeline to be in a full-open state, and determining the flow of the magnetic suspension blower to be the maximum flow when the valve is in the full-open state;
s306, adjusting the opening of a valve of the air outlet pipeline to enable the magnetic suspension blower to be in a surge state, and determining the flow of the magnetic suspension blower to be the minimum flow when the magnetic suspension blower is in the surge state;
s307, determining a performance test range based on the maximum flow and the minimum flow;
s308, determining a performance test point based on the performance test range;
s309, recording preset parameters of the performance test points;
s310, determining a performance curve of the magnetic suspension blower at a preset rotating speed based on preset parameters.
The steps S301 to S302 and S305 to S310 are the same as the implementation of the steps S201 to S207 in the above embodiment, and are not described herein.
In step S303, the maximum operation efficiency of the fan is already set in the design link of the fan, that is, the fan is set to work at a certain flow rate with a certain rotation speed, so that the control system can directly obtain the parameter of the maximum operation efficiency of the fan. In the test process, the control system adjusts the rotating speed of the fan and the opening degree of the valve, and the operation efficiency of the fan is determined through the ratio of ideal compression work (no loss) to the operation power of the fan. Because the working state of the fan can be influenced by the ambient temperature, the humidity and the pressure, in order to improve the accuracy of the operation efficiency, the operation efficiency of the fan needs to be comprehensively calculated and obtained by considering the parameters such as the ambient temperature, the pressure and the like when the operation efficiency is calculated.
If the fan can be in the maximum operation efficiency state through the adjustment of the opening degree of the valve, that is, the current operation efficiency of the fan is the same as the set maximum operation efficiency, step S304 is executed, and the preset parameters of the fan in the maximum operation efficiency state are recorded for drawing the subsequent performance curve. If the fan cannot be in the state of maximum operation efficiency through adjustment of the opening of the valve, that is, the current rotation speed is not suitable, the step S301 is executed in a returning mode, the rotation speed of the fan is adjusted to other preset rotation speeds, and then the fan is in the state of maximum operation efficiency through adjustment of the opening of the valve.
In the method, the control system records the preset parameters of the fan in the maximum state of the running efficiency, so that the drawn performance curve is more accurate, the problems of the fan can be quickly found through comparison with the performance curve, the accuracy of testing the fan is improved, and the testing time is saved.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure herein.
