- 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: What is an extruder?
- This method of forming is continuous molding, such as pipes, plastic profiles, films and so onThe machine also has a single screw, twin-screw, multi screw points.The forming methods are single extrusion and coextrusion only.
- 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: producing polyethylene polypropylene fiber, masterbatch in the dark spot under the light, that is, masterbatch does not change, filter replacement frequently, half an hour... 40The equipment is Changzhou Riyue extruding machine, production of polyethylene polypropylene masterbatch, a dark spot in the light, it is not frequent replacement of masterbatch, filter plugging, half an hour, I added the 30% filling masterbatch, how to solve this problem? Other particles are not wet either. Masterbatch is not turned for help
- 7042, no tax 9350-9400 yuan / ton, 02TN26 no tax,
- Q: extrusion machine prone to coke material, what is the cause? How to improve or solve?
- Is the place where the material is easy to burn rough? Add stabilizers and lubricants appropriately.
- 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: 1: what is the difference between an extruder and an injection molding machine?Answer the questions in terms of structure, process, product difference, material distinction, mould distinction and development areaThis is a kind of mechanical professional mold mold equipment on an essay question, please the professional teacher to help answer, thank you very much, the students have urgent need, thank you!!
- 1: extruder, is threaded through the push rod, the plastic die forming process by melting in the forward process. After the extruder products are silk, belt, tube, plate, etc. 2: injection molding machine, mainly to melt the plastic injection molding process, after the mold injection molding machine outjection. The main products are mechanical parts, containers, household appliances shell.
- 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!
- Fan, water pump at low speed, torque is not enough, resulting in high current, if vector control can be ideal.
- Q: The working principle of an extruder
- The material is moved forward by the extrusion of the screw and the barrel, and the material is fully homogeneous and plasticized in the process of material advance. Then the material is extruded by a certain shape of the die by the die of the die.
- Q: What are the components of an extruder?
- The driving system of an extruder is to drive the screw, providing the torque and speed required by the screw in the extrusion process, usually consisting of an electric motor, a reducer, and a bearing.3. heating and cooling device for extruderHeating and cooling are necessary conditions for the process of making a plastic extruder. It includes two aspects:(1) now host extruder is usually divided into electric heating, resistance heating and induction heating, heating installed in the fuselage, neck, head of each part. The heating device heats the plastic in the outer barrel to increase the temperature required for the process operation.(2) the cooling device is designed to ensure that the plastic is in the temperature range required by the process. Specifically, to eliminate the excess heat generated by the shear friction of the screw rotation, in order to avoid the temperature is too high, so that plastic decomposition, coke burning or stereotypes difficult. Cylinder cooling water cooling and air cooling is divided into two kinds, small and medium sized extrusion machine adopts air cooling is more appropriate, large use more water or two kinds of combined cooling; cooling water cooling screw mainly adopts the center, the purpose is to increase the solids conveying rate, stable glue volume, and improve product quality; but in the cooling hopper one is, in order to strengthen transport of solid material, prevent warming plastic sticky jam outlet, two is to ensure the normal work of the transmission part.
