Embodiment
To describe technology contents, construction feature, institute's reached purpose and effect of utility model in detail, below in conjunction with implementation
Example simultaneously coordinates accompanying drawing to be described in detail.
As shown in Figure 1, main box 2 is connected with the extrusion die of tube extruding equipment, and die cavity is provided with main box 2
21, water tank 1 is connected to the lower section of main box 2 and is connected with die cavity 21.When tube extruding equipment carries out tube extrusion operation,
Water in water tank 1 can cool down to the extrusion die of high temperature.Vavuum pump 6 is connected with main box 2 and for being taken out to die cavity 21 very
Sky, in vavuum pump 6 in the vacuum of die cavity 21, the moisture that is easily mingled with part water tank 1, thus vavuum pump 6 with
Connection one is used for the gas-water separation mounting mechanism 61 for separating gas and water between main box 2.Pressure inverting is provided with main box 2
Device 3, pressure transmitter 3 have part to be deep into die cavity 21, and pressure transmitter 3 is used to detect the vacuum in die cavity 21.Pressure
Transmitter 3 is connected with the signal of controller 4, and by the vacuum feedback of the information detected to controller 4（Controller 4 in this case
Using model TE6-W intelligent control table）.Controller 4 is connected with the signal of frequency converter 5, and frequency converter 5 electrically connects with vavuum pump 6,
The vacuum information that frequency converter 5 feeds back according to pressure transmitter 3 adjusts the working frequency of vavuum pump 6 in real time.
Water tank 1 has a water filling port and a discharge outlet, and when water filling port is opened, the water level 11 in water tank 1 raises, die cavity 21
Interior vacuum becomes big, and the vacuum feedback of the information detected is transferred to by pressure transmitter 3 to controller 4, the signal of controller 4
Frequency converter 5, frequency converter 5 controls vavuum pump 6 to reduce its working frequency, so as to reduce the rate of air sucked in required of vavuum pump 6.When discharge outlet is opened
When, the water level 11 in water tank 1 reduces, and the vacuum of die cavity 21 diminishes, the vacuum feedback of the information that pressure transmitter 3 will detect
To controller 4, the signal of controller 4 is transferred to frequency converter 5, and frequency converter 5 controls vavuum pump 6 to improve its working frequency, so as to increase
The rate of air sucked in required of vavuum pump 6.So, a PID is collectively formed by pressure transmitter 3, controller 4, frequency converter 5 to adjust automatically
Unit is saved, such PID automatic adjustment units are according to the Vacuum shaping environment of tube extruding equipment, by adjusting vavuum pump in real time
6 working frequency, a stable Vacuum shaping environment is provided for tube extruding equipment, energy consumption is lower, production efficiency is higher.
PID automatic adjustment units also include memory, and memory is believed with pressure transmitter 3, controller 4, frequency converter 5 respectively
Number connection, memory are used to store each working frequency of corresponding vavuum pump under different vacuums, are easy to set for tube extrusion
Standby production different size, the tubing of model provide reference.
