Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, an internal cooling water circulation emergency system for a vacuum casting furnace comprises a circulation water tank 1, a water inlet valve 3, a one-way valve 5, an air-cooled radiator 7, an emergency water pump 4 and a filter 6, wherein the parts are communicated through a pipeline 2, and an emergency power supply 9 supplies power to the emergency water pump 4 and the air-cooled radiator 7. Softened water is adopted as circulating water, when sudden water cut-off is caused by any power failure, water pump failure and other reasons, an emergency power supply is automatically switched to supply power to the emergency water pump 4 and the air-cooled radiator 7, the softened water in the circulating water tank 1 is cooled by the air-cooled radiator 7 and then supplied to the vacuum casting furnace 8, and finally the softened water returns to the circulating water tank 1 and continuously supplies cooling water to the vacuum casting furnace 8 until the temperatures of an induction coil, a furnace body and the like of the vacuum casting furnace are reduced to be below safe temperatures.
Example 2: on the basis of embodiment 1, the emergency power supply 9 of the design is composed of a diesel generator set, a UPS uninterrupted power supply, a logic control part and an informatization management system. The electric control system is provided with a mains supply detection unit, and when the PLC detects that the mains supply is powered off, the UPS is started to supply power to the control system and the emergency water pump for 5 min. In the process, the diesel generator is started to generate power, the power is automatically switched to the generator to supply power after the power generation is stable, the cooling fan is started, the normal running of circulating cooling water is ensured, and the emergency power supply of the vacuum casting furnace is started at the same time. The system is provided with an Uninterruptible Power Supply (UPS) and supplies power to an emergency water pump, a Programmable Logic Controller (PLC), an electromagnetic valve and other sensors under the condition that the power generation of the generator is not stable enough.
