[0042] Implementation method 1:

[0043] like Figure 1 and Figure 2 As shown, the present invention provides a cooling control method for an extra-large hot isostatic pressing equipment, which is used to control the cooling water flow in multiple operating units in the hot isostatic pressing equipment. Each operating unit is provided with a cooling branch pipe, and each cooling branch pipe is connected to a cooling main pipe 20. The cooling control method includes:

[0044] Step S1: Monitor the current temperature in each operating unit and calculate the difference ΔT between the current temperature and the target temperature n ;

[0045] Step S2: Obtain the flow coefficient Q of each operating unit according to the current working stage of the hot isostatic pressing equipment n and component factor A n , and calculate the flow adjustment value ΔQ of each operating unit n =A n ×Q n ×ΔT n ;

[0047] Step S4: Adjust the value ΔQ according to the total flow 总 Adjust the flow rate of cooling water in the cooling main pipe 20.

[0048] The cooling control method for extra-large hot isostatic pressing equipment described in the present invention sets corresponding weighted coefficients according to the cooling requirements of each operating unit in the current working stage, and calculates the flow adjustment value in the cooling main pipe 20 according to each weighted coefficient; only one set of feedback control devices needs to be set to adjust the flow of cooling water in all operating units. On the one hand, the number of feedback control devices can be reduced and the investment cost can be reduced. On the other hand, the complexity of the equipment cooling system can be reduced, and the number of components in the system can be reduced to reduce its failure rate, thereby ensuring the stability and safety of the hot isostatic pressing equipment during operation.

[0049] The detailed process of each step of the cooling control method for super-large hot isostatic pressing equipment described in the present invention will be described below.

[0050] In step S1, the cooling temperature difference ΔT is monitored and calculated. n :A temperature monitoring mechanism (usually a temperature sensor) is set in each operating unit to monitor the temperature in each operating unit in real time. The target temperature refers to the temperature value to which the operating unit needs to be cooled (or the temperature range that needs to be maintained). The target temperature is usually an adjustable temperature value for operating units in different working stages. The operator can adjust the target temperature according to the actual needs of the operating unit.

[0051] In step S2, the flow coefficient Q is obtained. n and component factor A nAnd calculate the flow adjustment value ΔQ n : Flow coefficient Q n An adjustable correction flow value based on the historical cooling data of each operating unit; component coefficient A n It is an adjustable correction coefficient value formulated according to the structure of each operating unit; flow coefficient Q n and component factor A n Usually it can be directly obtained according to the model of the operating unit and the working stage, and the operator can adjust it according to the actual needs of the operating unit in different equipment models. n The data is calculated based on the process cooling and heat exchange needs. The basic principle is energy conservation, that is, the energy of cooling water heating is balanced with the energy loss caused by cooling inside the equipment, and is corrected according to the actual operation data of the equipment; the flow coefficient Q of each operating unit in the hot isostatic pressing equipment n Common range: 100m³ / h~200m³ / h. Component coefficient A n In order to distinguish the differences in specific heat and heat transfer coefficient of cooling medium required by different components (operating units), the component coefficient is obtained by fitting after the flow coefficient is determined according to the actual operation data of the component; the component coefficient A of each operating unit in the hot isostatic pressing equipment n The commonly used range is: 0.1~0.8.

[0052] In step S3, the flow weighting coefficient Xn is obtained and the total flow adjustment value ΔQtotal is calculated: the flow weighting coefficient Xn is an adjustable weighting coefficient value formulated according to the working status of each operating unit in each working stage. n Usually, it can be directly obtained according to the working stage of the operation unit model, and the operator can adjust it according to the actual needs of the operation unit; the sum of the flow weighted coefficients of each operation unit is X1+X2+…+X n =1.

[0053] Furthermore, the operation unit includes a compressor, a cylinder, upper and lower plugs, a hydraulic unit and a vacuum unit, and the compressor, the cylinder, the upper and lower plugs, the hydraulic unit and the vacuum unit are all provided with cooling branches and temperature monitoring mechanisms; the working stages include vacuum stage, pressurization stage, mechanism adjustment stage, heating stage and cooling stage performed in sequence. The cylinder and the upper and lower plugs are combined to form a molding container, and the compressor, the hydraulic unit and the vacuum unit are all connected to the molding container. In the vacuum stage, the vacuum unit starts to vacuum the molding container; in the pressurization stage, the compressor starts to inflate and pressurize the molding container; in the mechanism adjustment stage, the hydraulic unit starts to adjust the positions of the components in the molding container, and keeps the compressor in a working state; in the heating stage, the heating unit is started to heat the molding container, and the compressor and the hydraulic unit are kept in a working state; in the cooling stage, the molding container is cooled by the cooling main pipe and each cooling branch pipe. In each of the above stages, the cooling main pipe and the cooling branch pipe are in an open state, which is used to cool each operation unit in real time.

[0054] The flow weighting coefficients of the compressor, cylinder, upper and lower plugs, hydraulic unit and vacuum unit are X1, X2, X3, X4 and X5 respectively; and X1+X2+X3+X4+X5=1.

[0055] In the vacuum stage, X1=X2=X3=X4=0, X5=1;

[0056] In the pressurization stage, X1=1; X2=X3=X4=X5=0;

[0057] In the stage of institutional adjustment, X1=X2=X3=X5=0, X4=1;

[0058] In the heating stage, X1=0.6~0.8, X2=0~0.2, X3=0~0.1, X4=0.1~0.2, X5=0;

[0059] During the cooling stage, X1=0, X2=0.2~0.6, X3=0.2~0.6, X4=0~0.1, X5=0.

[0060] Preferably, when the current temperature in any operating unit is monitored to exceed the limit temperature of the operating unit, the flow weighting coefficient X corresponding to the operating unit is increased. n Adjust to 1, the flow weighting coefficient X corresponding to other operating units n Adjust to 0.

[0061] The limit temperature refers to the maximum temperature that the operating unit can withstand in a short period of time. It is related to the structure of the equipment itself and is usually a fixed temperature value. If the operating unit is at this limit temperature for a long time, it will cause damage to the operating unit. In any working stage, if the current temperature in any operating unit is monitored to exceed the limit temperature of the operating unit, the operating unit will be in a dangerous working state. At this time, the flow weighting coefficient X of the operating unit is directly increased. n Adjust to 1, then the total flow adjustment value ΔQ 总 It directly depends on the operating unit, thereby achieving rapid cooling of the operating unit to avoid damage.

[0062] In step S4, the flow rate of cooling water in the cooling main pipe 20 is adjusted: the total flow rate adjustment value ΔQ is obtained through the above steps S1 to S3 总 , the value ΔQ 总 That is, corresponding to the flow change value in the cooling main pipe 20, the output power of the circulating water pump 23 on the cooling main pipe 20 is adjusted by the control unit 40, and the flow change in the cooling main pipe 20 is monitored at the same time, so that the flow of cooling water in the cooling main pipe 20 is adjusted to the currently required flow value.

The cooling needs of each operating unit are met by adjusting the flow in the cooling main pipe 20. There is no need to set a corresponding feedback control device for each cooling unit, which reduces the complexity of the equipment cooling system, reduces the number of components in the system to reduce its failure rate, and ensures the stability and safety of the hot isostatic pressing equipment during operation.

[0069] Specifically, Figure 1As shown, the cooling main pipe 20 includes a water inlet pipe 21 and a water outlet pipe 22. The inlet of the water inlet pipe 21 is connected to the cooling water tank 30, and the outlet of the water inlet pipe 21 is connected to the hot isostatic pressing equipment.
