Q: For example, 70 square conductors, the outer diameter is A, out of the insulation, then the line mouth to choose how much, how much plastic cover election? Then the sheath, then how to choose the mold?: Depending on your specific specifications, if XLPE is insulated, extrusion die with small touch line, set on the use of cable diameter, large core conductor than a few tenths of good, if you like to use 70 square tube extruding mold insulation of the conductor element some is big 1 can be set according to the touch, the tensile ratio calculation, PVC1.6 DYWL material with smaller good-looking it is simple of the extrusion process

Q: Why is the connection between the extruder and the switchboard?. The upper and lower three terminals are short circuited: The action should be to require three simultaneous electricalOr a two way backup

Q: Wire and cable extrusion machine temperature exceeds the process documentation, what are the reasons?: As far as actual production is concerned, it is necessary to go beyond the regulations to produce normally

Q: Why will the extruder frequency shift stop?: Because the frequency converter is out of order, you can look at the fault record parameters of the inverter.

Q: What is the adjustment method of China's extrusion machine die?: (5) sense of mold: it is the method of experience versus mold. Feel the thickness of the plastic layer by hand and adjust the mold. The utility model is suitable for the outer protective layer of large cross section wire and cable.

Q: Why can the plastic extrusion machine extrude the flat bar?: What's the reason for pulling out the stripes?1, the vacuum is not enough.2, high temperature settings.3, formula lubrication is too much

Q: What should be paid attention to in the daily maintenance of the extruder?: Extrusion machine regular maintenance mainly has these aspectsdrive system(1) check the temperature rise of motor and oil tank, whether the bearing is overheated locally, the abnormal noise of motor and gear, oil leakage, radial circle of oil filter and spline shaft, and the contact gap with the end of screw.(2) regularly clean the oil filter and remove the dirt at the bottom of the tank, and lubricate the lubrication points regularly.(3) the new gear box has been filled with gear oil, and new oil will be replaced every 4000 hours after the operation.

Q: Taper twin screw extrusion machining of plastic masterbatch? What ancillary equipment do you need?: Can, but need feeding machine and related auxiliary mixing granulator, the cost is not low, but the effect is less than double make flat, because itself is not suitable for the design of double cone, adjustment of the formula is the key.

Q: There is a 90 extrusion machine, used in the production of communication cables (outside the cable core is extruded with a layer of LLDPE), now is the configuration of Y2-280M-490KW167A inverter type ACS510197A + ABB), General Motors now found low speed when the current is too large, what reason? How to solve? The details are as follows: used for communication cable production HYA30*2*0.4, 1, line speed is 50 m / min, inverter display frequency 35.3HZ current: 116A; 2, line speed is 40 m / min, inverter display frequency of 28.2hz, current: 140A3, line speed is 35 m / min, the frequency converter significantly method: 157A 24.6HZ frequency current, because the product variety and technical reasons, we need to be in the frequency of 10HZ production. Now, it seems that if I reduce the speed again, the current will probably exceed the rated current. What should I do? Is the motor changed to frequency conversion motor? Or inverter? How to solve? Please heroes pointing, thank you!: See the ACS510 manual, this type of inverter used in fan pump type, 2605 control methods of determining its U/F, the default value is 2 (the square type, namely fan pump type); for constant torque load, should be set to 1 (linear). When not available, does the debugger not modify the parameter to 1? If that's the case, will the top floor say what happened?

Q: The working principle of an extruder: What is the working principle of an extruder?:Screw with specific shape,Turn in a heated barrel,It will be delivered from the hopperThe plastic is pressed forward, allowing the plastics to be uniformly plasticized (i.e., melted)Through the head and different shapes of the mold, the plastic extrusionA continuous plastic layer of various shapes, extruded on the core and cable.
