TECHNICAL FIELD

[0002] The magnetic energy-saving pump is a kind of fluid conveying device which realizes shaft seal-free and leakage-free transmission by using magnetic coupling. The core of the magnetic energy-saving pump is that the permanent magnets between the inner rotor and the outer rotor are attracted to each other to transmit torque, so that the mechanical seal between the pump shaft and the motor is not needed, and the shaft seal wear and leakage risk are eliminated. At the same time, the low friction loss, no lubrication requirement and efficient magnetic field coupling design make the whole machine have lower energy consumption, longer service life and more reliable operation performance than the traditional mechanical seal pump under the conditions of medium-low flow and medium-high lift, and are widely used in petrochemical, chemical, pharmaceutical and power and other occasions which require strict sealing and energy saving and emission reduction.

[0003] In the prior art, the liquid cooling heat dissipation device often depends on a kind of cooling liquid, and cannot select an appropriate cooling liquid according to the working environment of the liquid cooling heat dissipation device. At the same time, the heat dissipation of the point heat source in the magnetic energy-saving pump only relies on one of the liquid cooling heat dissipation device or the air cooling heat dissipation device. When either of the heat dissipation devices is running at full power, the real-time heat source temperature of the point heat source cannot be reduced to the normal working temperature within the minimum heat dissipation time, resulting in the occurrence of demagnetization of the permanent magnet in the point heat source.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] Example 1, please refer to Figures 1-4 As shown, the technical solution provided by this invention is: a magnetic energy-saving pump heat dissipation method, the specific method of which is as follows:

[0074] Step S1: Obtain basic data of the point heat source inside the magnetic energy-saving pump, monitor the real-time heat source temperature of the point heat source, and calculate the heat released by the point heat source within a fixed monitoring period.

[0075] It should be noted that the basic data includes the weight and specific heat capacity of the point heat source; the specific heat capacity is the amount of heat that a fixed weight of point heat source needs to absorb to increase its temperature by 1°C.

[0076] Specifically, the real-time heat source temperature of the internal heat source of the magnetic energy-saving pump is monitored using temperature sensors and phase change monitoring devices.

[0077] Specifically, the heat source of the magnetic energy-saving pump is the permanent magnet area of ​​the magnetic coupler inside the magnetic energy-saving pump. When the motor of the magnetic energy-saving pump is running, it generates heat in the heat source, causing the temperature of the heat source to rise.

[0078] In this embodiment, step S1 includes the following sub-steps:

[0079] Step S11: Obtain the start time node and current time node of the magnetic energy-saving pump, and subtract the start time node from the current time node to obtain the running time of the magnetic energy-saving pump.

[0080] Step S12, as follows Figure 2 As shown, the real-time heat source temperature of the point heat source per minute during the operation of the magnetic energy-saving pump is obtained through the phase change monitoring device.

[0081] No action is taken when the real-time temperature of the heat source is lower than the warning temperature.

[0082] When the real-time heat source temperature of the point heat source is greater than or equal to the warning temperature, the phase change monitoring device sends a warning temperature instruction, and enters the next step;

[0083] The warning temperature is specifically the demagnetization temperature of the permanent magnet of the magnetic coupling device in the magnetic energy-saving pump, and in the embodiment, the warning temperature is 70°C, and the demagnetization temperature of the permanent magnet is 80°C.

[0084] Specifically, the phase change monitoring device is composed of a phase change material unit, a heat bridge block, an instruction sending unit and a power supply. The heat bridge block can be copper, aluminum or graphite, etc., which is used to conduct the heat of the point heat source to the phase change material unit. The phase change material unit contains a mixed material composed of a phase change material and a conductive material. The phase change material can be paraffin, stearic acid, beeswax or naphthalene, etc. Since the melting point of naphthalene is 80°C, naphthalene is preferred as the phase change material in the embodiment. The conductive material can be graphite powder, silver powder or carbon black, and graphite powder is preferred as the conductive material in the embodiment. When the temperature of the phase change material unit reaches the warning temperature, the mixed material in the phase change material unit changes from solid to liquid, so that the circuit of the phase change monitoring device is closed, and then the warning temperature instruction is sent through the instruction sending unit.

[0085] In step S13, any time node in the running time length of the magnetic energy-saving pump is taken as a first time node, and the real-time heat source temperature of the point heat source corresponding to the first time node is recorded as a first heat source temperature.

[0086] In step S14, a plurality of time nodes after increasing the fixed monitoring time length are taken as second time nodes based on the first time node, the real-time heat source temperatures corresponding to the plurality of second time nodes are recorded as second heat source temperatures, the second heat source temperatures are subtracted from the first heat source temperature to obtain a plurality of temperature difference values of the point heat source, and the plurality of temperature difference values of the point heat source are added to obtain an average temperature difference value DRC.

[0087] In specific implementation, the fixed monitoring time length is less than or equal to the running time length of the magnetic energy-saving pump, and the fixed monitoring time length is five minutes.

[0088] For example, the first time node is 18:40, and the fixed monitoring time length is 5 minutes, so the second time node can be 18:45, 18:50, 18:55, 19:00, etc.

[0089] In step S15, the weight DZL and the specific heat capacity DBR of the point heat source are obtained, and the point heat source heat DRL released by the point heat source in the fixed monitoring time length is calculated through a thermodynamic formula, and the formula is specifically as follows:

[0090] DRL=DZL×DBR×DRC.

[0091] In step S2, the basic device data of the liquid cooling heat dissipation device in the magnetic energy-saving pump and the basic test data of the magnetic energy-saving pump are obtained, and the heat dissipation capacity of different coolants on the point heat source in the magnetic energy-saving pump is analyzed to obtain a coolant suitable for the current liquid cooling heat dissipation device.

[0092] The device basic data includes the specific heat capacity of the coolant of the liquid cooling heat dissipation device, the density of the coolant, the coolant volume flow, the real-time outlet temperature and real-time inlet temperature of the coolant in the liquid cooling heat dissipation device, the heat exchange coefficient between the coolant and the point heat source, and the contact area between the liquid cooling heat dissipation device and the point heat source. The coolant volume flow is specifically the maximum flow volume of the coolant per second in the liquid cooling heat dissipation device, and the unit of the coolant volume flow is liter / second.

[0093] The basic test data includes the temperature of the substance conveyed in the magnetic energy-saving pump, the heat exchange area between the substance and the point heat source, and the heat exchange coefficient between the substance and the point heat source.

[0094] In specific implementation, the coolant in the liquid cooling heat dissipation device can be deionized water, 50% ethylene glycol aqueous solution or 1% CNT slurry.

[0095] Specifically, the heat dissipation capacity of different coolants on the point heat source in the magnetic energy-saving pump is used.

[0096] It should be specifically pointed out that the temperature of the substance conveyed by the magnetic energy-saving pump in the embodiment is a fixed temperature, and the substance flow is a fixed flow.

[0097] In the embodiment, the step S2 includes the following sub-steps:

[0098] In step S21, the coolant volume flow TJL and the coolant density ρi of the liquid cooling heat dissipation device are obtained, wherein i is the number of the coolant, i=1, 2, …, n, n is the maximum coolant number, and the coolant volume flow is converted into the coolant weight flow ZLLi by the formula, and the formula is specifically as follows:

[0099] ZLLi=ρi×TJL, wherein the coolant weight flow is specifically the flow weight of the coolant per second in the liquid cooling heat dissipation device, and the unit of the coolant weight flow is kilogram / second.

[0100] In step S22, the real-time inlet temperature SRW, the real-time outlet temperature SCWi and the specific heat capacity LBRi of the coolant in the liquid cooling heat dissipation device are obtained, and the heat absorption amount LXLi of the liquid cooling heat dissipation device is calculated by the heat power calculation formula, and the formula is specifically as follows:

[0101] LXLi=ZLLi×LBRi×(SCWi-SRW);

[0102] Step S23, the point heat source releases the point heat source heat DRL in the fixed monitoring time length, and the fixed monitoring time length GJS is obtained, and the average heat power PRG of the point heat source is calculated by the heat power calculation formula, and the formula is as follows:

[0103] PRG=300×DRL / GJS;

[0104] Step S24, the heat exchange coefficient LDRi between different cooling liquids and the point heat source, the contact area JCM of the liquid cooling heat dissipation device and the point heat source, and the warning temperature JGW are obtained, and the heat absorption power LXGi of different cooling liquids is calculated by the formula, and the formula is as follows:

[0105] LXGi=LDRi×JCM×(JGW-SRW);

[0106] Step S25, the substance temperature WZW of the substance transported in the magnetic energy-saving pump, the heat exchange area RJM between the substance and the point heat source, and the heat exchange coefficient RJX between the substance and the point heat source are obtained, and the steady-state temperature WTWi corresponding to all cooling liquids is calculated by the Fourier formula, the Newton cooling formula and the steady-state heat balance formula, and the formula is as follows:

[0107] WTWi=(RJX×RJM×WZW+LDRi×JCM×SRW) / (RJX×RJM+LDRi×JCM);

[0108] It should be specifically pointed out that the steady-state temperature corresponding to the cooling liquid is the temperature that makes the real-time heat source temperature of the point heat source stable when the liquid cooling heat dissipation device works;

[0109] Step S26, the heat absorption power of all cooling liquids is calculated, if the heat absorption power of any cooling liquid is less than the average heat power of the point heat source, it is determined that the cooling capacity of the corresponding cooling liquid to the point heat source is unqualified, and is removed; if the heat absorption power of any cooling liquid is greater than or equal to the average heat power of the point heat source, the corresponding cooling liquid is recorded as a preliminary qualified cooling liquid, and the next step is performed;

[0110] Step S27, the steady-state temperature corresponding to all preliminary qualified cooling liquids is compared with the warning temperature;

[0111] If the steady-state temperature corresponding to any preliminary qualified cooling liquid is greater than the warning temperature, it is determined that the preliminary qualified cooling liquid is unqualified, and is removed;

[0112] If the steady-state temperature corresponding to any preliminary qualified cooling liquid is less than or equal to the warning temperature, the preliminary qualified cooling liquid with the lowest steady-state temperature is selected as the cooling liquid of the liquid cooling heat dissipation device;

[0113] Step S28: If there is no pre-qualified coolant with a steady-state temperature less than or equal to the warning temperature, increase the contact area between the liquid cooling device and the permanent magnet area or increase the coolant volume flow rate, and repeat the above steps until the steady-state temperature of any pre-qualified coolant is less than or equal to the warning temperature, then use the corresponding pre-qualified coolant as the coolant for the liquid cooling device.

[0114] Step S3: Obtain the minimum heat dissipation time of the internal heat source of the magnetic energy-saving pump, analyze the heat dissipation capacity of the liquid cooling device, and determine whether the magnetic energy-saving pump needs secondary heat dissipation.

[0115] It should be specifically noted that when the real-time heat source temperature of the point heat source is greater than or equal to the warning temperature, the permanent magnet will maintain its magnetism for the maximum duration. The heat dissipation device of the magnetic energy-saving pump needs to reduce the real-time heat source temperature of the point heat source to less than the warning temperature within the maximum duration that the permanent magnet maintains its magnetism. The corresponding cooling time is the minimum heat dissipation time.

[0116] In this embodiment, step S3 includes the following sub-steps:

[0117] Step S31, as follows Figure 3 As shown, a heat dissipation curve of a point heat source is constructed, including the real-time heat source temperature curve and the real-time coolant temperature curve. The positive X-axis represents the duration in seconds, and the positive Y-axis represents the temperature in degrees Celsius.

[0118] Step S32: When the real-time heat source temperature curve of the point heat source intersects the warning temperature example line for the first time, the time corresponding to the intersection point is the initial start-up time node of the liquid cooling heat dissipation device. At the same time, at the initial start-up time node, the point heat source is cooled by the first operating power of the liquid cooling heat dissipation device.

[0119] The first operating power is a fixed percentage of the maximum operating power of the liquid cooling heat dissipation device;

[0120] Step S33: When the real-time heat source temperature curve of the point heat source intersects with the warning temperature example line for the second time, the duration corresponding to the intersection point is the stable heat dissipation time node. Subtract the stable heat dissipation time node from the initial start-up node to obtain the initial heat dissipation time of the liquid cooling heat dissipation device at the first operating power.

[0121] Step S34: If the initial heat dissipation time of the liquid cooling heat dissipation device at the first operating power is less than or equal to the minimum heat dissipation time, then the first operating power of the liquid cooling heat dissipation device is determined to meet the standard, and the first operating power is taken as the standard operating power.

[0122] If the initial heat dissipation time of the liquid cooling heat dissipation device at the first operating power is greater than the minimum heat dissipation time, it is determined that the first operating power of the liquid cooling heat dissipation device does not meet the standard, and proceed to the next step;

[0123] Step S35: Using the first operating power of the liquid cooling heat dissipation device as a benchmark, increase the fixed power upward until the maximum operating power of the liquid cooling heat dissipation device is reached, and obtain the corresponding heat dissipation time. When the heat dissipation time corresponding to any operating power is less than or equal to the minimum heat dissipation time, it is determined that the corresponding operating power meets the standard and is used as the standard operating power. The magnetic energy-saving pump does not need to perform secondary heat dissipation.

[0124] When the heat dissipation time corresponding to all operating power is greater than the minimum heat dissipation time, it is determined that the magnetic energy-saving pump needs secondary heat dissipation, and the process proceeds to step S4.

[0125] Step S4: Obtain the actual heat dissipation power of the air-cooled heat dissipation device, perform secondary heat dissipation on the point heat source of the magnetic energy-saving pump through the air-cooled heat dissipation device, and analyze the heat dissipation capacity of the air-cooled heat dissipation device and the liquid-cooled heat dissipation device on the point heat source when they are running simultaneously.

[0126] In this embodiment, step S4 includes the following sub-steps:

[0127] Step S41, as follows Figure 4 As shown, a secondary heat dissipation curve of a point heat source is constructed, where the positive X-axis represents the duration in seconds and the positive Y-axis represents the temperature in degrees Celsius.

[0128] Specifically, the secondary heat dissipation curve of the point heat source is the real-time heat source temperature change curve when the air-cooled heat dissipation device and the liquid-cooled heat dissipation device are running simultaneously.

[0129] Step S42: When the secondary heat dissipation curve of the point heat source intersects the warning temperature example line for the first time, the duration corresponding to the intersection point is the secondary heat dissipation start-up node.

[0130] Step S43: Based on the secondary heat dissipation start-up node, increase the minimum heat dissipation time upwards to obtain the maximum heat dissipation time node;

[0131] Step S44: Obtain the time node when the slope of the secondary heat dissipation curve of the current heat source is zero after the first intersection with the warning temperature example line. This time node is the highest heat source temperature, and the corresponding time node is the cooling time node.
