The general principle of this full-liquid type high temperature fortune water type mould constant temperature machine and specific works process:
Full-liquid type full-liquid type high temperature fortune water type mould constant temperature machine is after receptacle water being placed on sealing, and the pressure in container is pressurized to corresponding pressure thus changes the boiling point of water, water is under the pressure state of 10kg ~ 20kg, and its boiling point is 180 ° to 200 °.Constantly temperature-compensating and constant temperature is done to mould again by high-temperature water pump.
Concrete is as follows:
Open magnetic valve 3, device is after 90s after filtration enters into water inlet pipe 40 for cold water, then enters from the second water inlet bypass pipe 402 and enters water pump 30 from backwater separator 302 after flowing through two check valves and finally flow to heater 20; While cold water enters heater and system pipeline, intrasystem air is constantly discharged from going out water diverter 201 and flows through the first water outlet bypass pipe 501, finally discharges from magnetic valve 3; Along with constantly adding of water, the water level of water in heater 20 constantly rise until the peak of heater 20 time magnetic valve 3 close.While adding water, heater 20 constantly carries out heated constant temperature to water, and water then constantly circulates by water pump 30.This circulation is flowed out from the water diverter 201 that goes out of heater 20, after flowing through mould, is back in heater 20 from backwater diffluence device 302.
