heating time.Main Equipment According to the design conception of this project, all the main equipments are made in Chinaa) Feeder air pump with the negative pressure, auto-control for the up feeder.b) Extruder: Ø130mm, L/D =30:1, driven by alternating current motor, auto-control for the
temperature and pressure.c) Blending system for the colorful PP articles: metering and blending automatically and exactly
so as to make the color and luster uniform.d) Cut and pull model (Ø150)e) Spinning manifold: with single die and modulef) Heating system: heating extruder with electricity, heating the other parts with recycled heating
system according to the customer requirement.g) Cooling system: this production using two sides air cooling system in order to make the full
dragging and assure the fiber quality.h) Drawing machine: drawing and making the fiber thin with the cooling air.i) Web former: collecting the fiber with the help of the negative pressure drawing so as to get the
continuous web. It is made of gear change mechanism, frame, transmission apron and air
suction system.j) Transmission apron: carrying the web to the calander for thermal-bonding.k) Calander: mainly for web consolidation. There will be some deformation and melting in the web
under the condition of high pressure of heating. So the bonding points come into being after
cooling which makes the web to be a kind of nonwovens with certain property and appearance.
Because it is one of the most important equipments of this project, in order to reduce the cost
of the customer use their own design technology to make the calander. The specification of the
calander is as follow: Effective Width: 1600mm Max speed: 150m/min Roller type: The up one surface is fluting and the down one surface is smooth. Roller diameter: 420mm Max temperature:200ºC Bonding area: as buyer's requirement Pressure: 50-100N/mm Temperature difference: ±1ºCl) Winder: mainly for winding the thermal bond nonwovens to be a certain quantity. It is made of frame, friction roller, roller auto-changing unit, rolling shaft, A/C motor and controlling systemm) Offline slitter: Mainly for cutting the nonwovens according to the request of the customer such
as length, width and weight.n) Assembly cleaning: through annealing oven and microwave oven. Checking the spinneret
orifice with microscopeElectricity Supply and AutocontrolBecause the electricity supply system is a big one, it is divided into three parts:a. High and low voltage system is designed by the customer.b. Lighting and small dynamical system are the responsibility of the customer.
c. The power and auto-control system are the responsibility of Party B(China)1. Transformation and distribution system for high and low voltagea. For all the electric design and base construction, a set of transformer of 315KVA is used with
the accessorial equipments.b. Low voltage distribution cabinet: with the type of Gck/L-0.4. It is compact of the structure with
drawer. So it is easy to fix, check and repair. At the same time it is also interchangeable so as
to reduce the stop time from accidents.2. Dynamical electricity supplyAccording to the processing, the request of this engineering is as follows:
