Problems solved by technology

[0003] However, it is difficult to drain the water in the water system. If the drainage is not clean, it may still cause the part of the pipeline in the water-cooled screw unit to freeze and damage, and it needs to be refilled when it is used again, which not only wastes water resources but also takes a long time. Exhausting the air in the water system, and manually turning on the water system regularly is not only a waste of labor, but also there is still a great risk of freezing in case of a sudden drop in temperature

Abstract

The invention discloses an anti-freezing method and a device of a water cooling threaded rod unit and the water cooling threaded rod unit. The method includes the following steps of acquiring the temperature of cooling water in the water cooling threaded rod unit and the temperature of freezing water in the water cooling threaded rod unit; judging whether the temperature of the cooling water is less than the first cooling water temperature threshold value or not, and meanwhile judging whether the temperature of the freezing water is less than the first freezing water temperature threshold value or not; when the fact that the temperature of the cooling water is less than the first cooling water temperature threshold value is judged, controlling a cooling water pump of the water cooling threaded rod unit to start, so that the cooling water in the water cooling threaded rod unit is in a flow state; and when the fact that the temperature of the freezing water is less than the first freezing water temperature threshold value is judged, controlling a freezing water pump of the water cooling threaded rod unit to start, so that the freezing water in the water cooling threaded rod unit is in a flow state. According to the method, when the temperature of the cooling water or the freezing water in the water cooling threaded rod unit is too low, the corresponding water pump can be started automatically to make the cooling water or the freezing water flow, so that the risk of freezing is reduced.

Description

technical field [0001] The invention relates to the technical field of water-cooled screw units, in particular to an antifreeze method for water-cooled screw units, a computer-readable storage medium, an antifreeze device for water-cooled screw units and a water-cooled screw unit. Background technique [0002] At present, most of the water-cooled screw units are installed indoors (for example, in the basement) and do not have antifreeze function. Therefore, in winter, the water in the water system of the water-cooled screw unit must be drained, or the water pump of the water system must be turned on regularly to make the water in the water system flow, to prevent freezing and damage to the pipeline and the water-cooled screw unit. [0003] However, it is difficult to drain the water in the water system. If the drainage is not clean, it may still cause the part of the pipeline in the water-cooled screw unit to freeze and damage, and it needs to be refilled when it is used aga...
