Wherein, the pushing block vertically connects the blade.
Wherein, the pushing block is provided with magnetic sheet, and the tachogenerator is Hall sensor.
Wherein, the die heater also includes frequency converter, and the frequency converter connects the controller and the water pump respectively.
Wherein, the die heater also includes communication module, and the communication module connects the controller.
Have the beneficial effect that：A kind of die heater of the utility model, by be arranged on die heater channel interior runner and set
Put outside pipeline tachogenerator to detect the rotating speed of runner, the tach signal measured is delivered to controller by tachogenerator,
The water flow value and hydraulic parameters value that controller is embodied according to tach signal deliver to display screen.Controller stores rotating speed in advance
Correspondence parameter library, because rotating speed, water flow value and hydraulic parameters value have unique corresponding relation, therefore only it is to be understood that rotating speed can
To obtain the water flow value and hydraulic parameters value of pipeline, a kind of sensor is so only needed just to measure two seed ginsengs of die heater
Number, greatly reduces equipment cost；Do not contacted directly with high temperature source in addition, tachogenerator is arranged on outside pipeline,
Therefore tachogenerator is not affected by high temperatures, and can improve the precision of detection.
Brief description of the drawings
Using accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not constituted to of the present utility model
Any limitation, on the premise of not paying creative work, can also be according to following attached for one of ordinary skill in the art
Figure obtains other accompanying drawings.
Fig. 1 is a kind of structural representation of die heater of the utility model.
Fig. 2 is the structural representation of paddle wheel flowmeter in a kind of die heater of the utility model and tachogenerator.
Include in fig. 1 and 2：1 --- ball valve, 2 --- filter, 3 --- temperature-sensing probe, 4 --- pressure release electromagnetic valve,
5 --- pressure switch, 6 --- water pump, 7 --- pressure gauge, 8 --- heater, 9 --- rotation flowmeter, 91 --- runner,

Embodiment
The utility model is further described with the following Examples.
As shown in figure 1, water inlet to be connected with turn between delivery port filter 2, pressure switch 5, water pump 6, heating
Device 8, paddle wheel flowmeter 9, temperature-sensing probe 3, ball valve 1, mould and pressure release electromagnetic valve 4, controller connect display screen, temperature-sensitive and visited respectively
First 3, pressure release electromagnetic valve 4, tachogenerator 10, heater 8 and water pump 6.Water flows through water inlet and enters pipeline, and water pump 6 is to current
Heater 8 is conveyed to after pressurization, heater 8 is heated to current, and the water after heating flows through paddle wheel flowmeter 9 and flows to mould,
To allow mould to maintain stationary temperature.As shown in Fig. 2 runner 91 is arranged on the channel interior of die heater, tachogenerator
10 are arranged on the outside of pipeline, and runner 91 includes four blades 911, and the end of each blade 911 is fixedly connected with pushing block 912, blade
911 can make current preferably promote runner 91 to rotate provided with pushing block 912, it is preferable that pushing block 912 vertically connects blade 911,
Runner 91 can be driven to rotate when current flow through runner 91, tachogenerator 10 can detect the rotating speed of runner 91, in order to carry
High measurement accuracy, pushing block 912 is provided with magnetic sheet, and tachogenerator 10 is Hall sensor, when magnetic sheet is close to tachogenerator 10
When, tachogenerator 10 once tests the speed with regard to counting so as to realize.
For each water pump 6, the water flow value of water pump 6, hydraulic parameters value, the current value of motor are all to have corresponding pass
System, when water pump 6 is run, the flowing of current can drive the rotation of runner 91, and the rotating speed of flow more great wheel 91 is faster, therefore
The current value of runner rotating speed, water flow value, hydraulic parameters value and motor is established correspondence pass by the application using this feature
System.The parameters such as the electric current of the rotating speed corresponding to each water pump 6, water flow value, hydraulic parameters value and motor are made thing by the application
First test, and test data is set up the storage of rotating speed correspondence parameter library in the controller.
Controller can calculate the actual power consumption amount of water pump 6 according to the motor current value measured, and for die heater, it consumes
Electricity maximum is heater 8 and water pump 6（Account for the 98% of entire machine power consumption）, and heater 8 can pass through controller monitoring
Actual operating frequency（Heater 8 is resistor-type, and its root Ju control temperature realizes ON/OFF frequent start-stop action）To calculate
Go out the actual power consumption amount of heater 8.Therefore any electronic device need not be increased（Such as current transformer）Can actually measured whole machine
The actual power consumption amount of device, and show on a display screen.
Every die heater has a unique number, and when many die heater operations, each die heater is connected by communication module
Monitor terminal is connected to, user just can obtain corresponding operating parameters and alarm logging in monitor terminal, to facilitate user to each
The monitoring of platform die heater row, maintenance.
As long as determining corresponding Model of pump in practical application, pass through turning for runner 91 detected by tachogenerator 10
Fast signal is sent to controller, and controller stores rotating speed correspondence parameter library in advance, due to rotating speed, water flow value, hydraulic parameters
Value and motor current value have unique corresponding relation, therefore only it is to be understood that rotating speed can be obtained by the numerical value of above-mentioned parameter, and handle
Above-mentioned parameter is shown on a display screen, so as to let the user know that the operating parameters of die heater, therefore only needs a kind of sensor can
To measure the different parameters of die heater, so greatly reducing equipment cost；In addition, tachogenerator 10 is arranged on outside pipeline
Portion is not contacted directly with high temperature source, therefore tachogenerator 10 is not affected by high temperatures, and can improve the precision of detection.
