The invention provides a pump operation method and a related device. When communication is lost, whether the current rotating speed of a pump is smaller than the preset rotating speed or not is judged, if the current rotating speed is smaller than the preset rotating speed, whether the current temperature of the pump is in the rising trend or not is judged, and if the current temperature is in the rising trend, the pump operates at the preset rotating speed, that is, the rotating speed of the pump is increased so as to reduce the pump temperature. Otherwise, the pump is dormant. When the current rotating speed is larger than the preset rotating speed, whether the current temperature of the pump is lower than the preset low temperature or not is judged, and if the current temperature is lower than the preset low temperature, the pump is dormant; if the current temperature is higher than the preset low temperature, whether the current temperature change trend of the pump is the rising trend or not is judged, and if the current temperature is the rising trend, the rotating speed of the pump is increased, and the pump temperature is reduced; otherwise, the pump does not act, or the current rotating speed of the pump is reduced to the preset rotating speed. The rotating speed of the pump can be adjusted when the pump cannot receive the rotating speed control instruction, the cooling requirement of the heat exchange system for the pump is met, and the energy consumption of the pump is reduced.

The application discloses a grinding and polishing equipment, a control method and device and a medium for a 3D printing product, and relates to the technical field of grinding and polishing. A first target product clamping unit and a first adjustment value corresponding to the first target product clamping unit are determined from a plurality of product clamping units; a second target product clamping unit and a second adjustment value corresponding to the second target product clamping unit are determined from the plurality of product clamping units based on a second force value, a second average value and second historical force data; and then compensation is performed according to the first adjustment value and the second adjustment value, so that the position of the product can be adjusted, the product being ground is compensated, the force borne by the product during grinding conforms to the change trend of the historical force data, the quality of the product after grinding is ensured, and the consistency of products in a plurality of stations can be improved.

This application belongs to the field of silicon steel strip production control technology, and discloses a silicon steel strip rapid cooling control method and system. By acquiring motion parameters such as the instantaneous speed and speed change trend of the target segment of the silicon steel strip before entering the cooling zone in real time, and combining them with the physical location information of the cooling zone, the method accurately predicts the expected time when the target segment arrives at the cooling zone and the expected residence time in the zone. Based on this, the method dynamically determines the required target cooling intensity according to the preset ideal cooling process and the expected residence time. At the same time, considering the inherent response time of the cooling actuator, the method calculates and determines the triggering time of the cooling command in advance. This method can effectively solve the problem of cooling inaccuracy caused by production line speed fluctuations in the prior art, avoid the steel strip outlet temperature from deviating from the preset value, thereby ensuring the initial conditions of the subsequent cooling zone and maintaining the stability of the morphology and distribution of precipitates.

The application discloses a method for early warning of abnormality of continuous casting equipment based on current change trend, which collects equipment fault information, collects current data of the equipment with faults and the equipment without faults as selected training set, analyzes the change law of the current data, and proposes a trend alarm mechanism; if the current value is increased in a short period, the trend alarm mechanism captures the current cumulative increase value in the short period; if the current value is slowly and steadily increased in a long period, the trend alarm mechanism captures the number of continuous days of increase and the cumulative increase amount of the current in the period; the over-limit condition characteristic value of the trend alarm mechanism is set, the current data of the equipment is collected and calculated, the over-limit condition characteristic value is met, and equipment abnormal early warning is given. The method monitors the current change trend of the equipment, constructs an early warning model based on the current change trend, compares and analyzes the data of multiple equipment, improves the accuracy and universality of the early warning model, and accurately early warns the equipment fault hidden danger.
