Q:the machine vibration is great, the motor, reducer are checked, no problem, there is abnormal sound.

Pay attention to the ground anchor.It is better to fasten the joint of the equipment itself.Is the fitting of the moving parts normal?.Is there an impact on the extrusion chamber?.

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:What is the temperature setting of the extruder and how much is the setting temperature of the head and filter?,

The temperature setting of the extruder is related to the material you manufacture. If the type of plastic is different, the setting temperature is different, and the material of different manufacturers is also slightly different from the temperature setting.

Q:Can PC and PP be extruded together with two materials in an extruder?

No co extrusion, PC polycarbonate, PP polypropylene, two kinds of product structure is not the same, not the same chemical composition, viscosity and liquidity is not the same, processing temperature and processing technology is also very different, and two kinds of products, so not incompatible, CO extrusion.

Q:What should be paid attention to in the daily maintenance of the extruder?

HostCheck the patency of cooling water, temperature (general / 26 C), feeding, cylinder temperature and pressure, friction condition of screw and barrel.NoseThe size loss of the perforated plate, the damage and corrosion of the runner surface, and whether the obstruction occurs affect the appearance and output of the product.

Q:How many roots are produced in an hour for an PVC tube extruder?

It depends on the type of your extruder and the specification of the tube you produced

Q:Taper twin screw extrusion machining of plastic masterbatch? What ancillary equipment do you need?

because itself is not suitable for the design of double cone, adjustment of the formula is the key.

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.

Q:Comparison of injection molding machines and Extruders

The plastic to replace steel or nonferrous metal, plastic cement, which is widely used in agriculture, building materials, packaging, machinery, electronics, automobiles, household appliances, petrochemical and defense, extruder and daily life other fields. So it can be predicted that in twenty-first Century, the plastic will be one of the most important raw material of human activities. The extruder design due to extrusion molding is the main form of plastic processing, so the development of plastic extrusion molding technology and equipment has important significance. The polymer materials used in blending type mixing equipment modification there are three main types: parallelwith twin-screw extruder, reciprocating screw kneader and series disc extruder. The small corotating twin screw extruder has domestic production can squeeze But tons of large mixing extrusion granulation unit will rely on the import machine technology. At the same time. Reciprocating screw kneader and series disc extruder is a necessary device for preparing high fill and high added value of polymer alloy, the current domestic research on them is just in the prototype stage, specifications, varieties not all, have broad prospects for development.

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!

Yes, the load characteristics and control characteristics are also to be matched. Otherwise, it will be very inappropriate and lead to abnormal phenomena.
