Respected users：

How are you!

When you receive this letter, on behalf of both sides have officially entered the stage of cooperation. This notice mainly enables you to understand the division for your purchase of equipment and the work done by the shipment, unloading, installation, commissioning, maintenance, training and other related information. In order to better cooperation, please read the following carefully, if in doubt, please call to consult.

Points to note

一,Matters for Attention

1-Pick up the goods

When you pick up the goods, please inform our business personnel after paying the balance in advance, and please make the delivery letter and provide the driver's basic information. Before loading, please inform the truck driver that we need to weld and fix the equipment to ensure that there is no displacement in transit resulting in equipment damage. In order for the equipment to arrive safely, please arrange your own escort or car, we do not bear the risk of transportation.

Unloading

When unloading, please arrange for professional operation. Pay attention to the lifting point of the equipment, and select the appropriate lifting and unloading equipment according to the weight indicated on the equipment nameplate.

Special attention: when the extruder hoisting, do not directly crane barrel position.

Attention to installation：

Personnel requirements：

To ensure that the equipment can be quickly put into production, we will arrange 1~2 installer personnel to your company to assist in the installation; ask your company to arrange at least 2~3 machine, electricity related staff to assist in installation, and learn equipment disassembly, maintenance related knowledge; when the equipment installation, our installer staff will start testing contract agreed on the corresponding specifications products production, please arrange your company's boot personnel, electronic control management personnel to assist in the boot, and by our installer staff to your company related staff boot operation training.

Site preparation

Factory Size Requirements：

The rest of the production line or special custom production line, please ask us for relevant data.

Requirements for lifting equipment：

The rest of the production line or special custom production line, please ask us for relevant data.

Equipment water requirements：

Water inlet

Water pressure：≥0.3Mpa; water temperature ：≤20℃(Part of PPR/PE High-speed pipe line water temperature≤20℃);

110 Below production line,water inlet pipe≥DN40;

250/450 Production line,water inlet pipe≥DN65;

630 Above production line,water inlet pipe≥DN80;

water outlet

110 Below production line,water outlet pipe≥DN125;

250/450 Production line,water outlet pipe≥DN250;

630Above production line,water outlet pipe≥DN400;

Water quality requirements

Equipment cooling class (including berral, reducer, water-cooled motor, oil temperature machine, industrial water-cooled air conditioning, etc)

Products cooling (including vacuum tank, spray tank, immersion tank, vacuum pump, etc)

Equipment gas requirements：

Equipment electricity requirements：

Please make sure that the supply voltage fluctuates：±5%;

Please buy the national standard cable of the regular manufacturer, please ask us for the specific model;

According to the total power of our production line, please choose the right transformer;

Please prepare the distribution cabinets to our main extruder cable, the production line internal wiring we have been equipped;

When the distance from the distribution cabinet to the extruder cabinet is more than 50 meters, the cable type should be used to prevent the cable from heating.

Precautions before the first boot of production line

Note: Before boot, please make sure to arrange boot, electrical personnel accompany to participate, and learn boot skills.

Water and electrical aspects

Please ensure that the water supply/drainage route has been installed and tested without leakage;

Please ensure that all circuits are installed and that the wiring is firm and not easy to fall off;

Please ensure that all grounding requirements are grounded;

Ensure that all air intakes are connected and the air inlet pressure is Mpa;0.5-0.7

The inlet temperature ≤25℃ for common production line and 16℃ for high speed production line;

Main Extruder, Coextruder Part

Please ensure that the reducer has been refueled, please refer to Annex 2 for specific brand number and refueling quantity;

Please ensure that the extruder main motor rotation direction is accurate (main motor coupling or reducer output with arrow marks);

Please make sure that the inlet pneumatic control of the water jacket section of the extruder barrel is available;Note:Turn off the ball valve when heating,turn it on when booting;

Die,calibrator

Please ensure that the installed die, pin and calibrator are consistent with those of the products planned;

Moulds with water cooling and oil cooling need to ensure that water cooling and oil cooling components are connected accordingly;

Please ensure that all heated temperature control areas are connected to the main cabinet one-to-one;

Please ensure that all porcelain plugs, thermocouples and pressure sensors are properly and firmly installed to avoid damage caused by poor contact;

Vacuum, cooling tank

Please ensure that the nylon plate specification installation is accurate, or nylon wheel position adjustment is accurate;

Please ensure that the vacuum pump has been opened, and the vacuum pump,water pump rotation direction is correct;

Make sure that the front and rear movement of the vacuum tank is available and that the bottom plate has been fitted with expansion screws;

Please adjust the alignment of the sizing calibrator and the die and pin at the entrance of the vacuum tank as far as possible;

Hual-off unit,cutting unit

Make sure that the haul-off's pressing, loosening and up and down electric functions are tested and available;

Please ensure that the cylinder pressure of the haul-off has been adjusted, normal positive pressure 0.5~0.7 Mpa, thin-walled tube to reduce the positive pressure, while opening the back pressure, to avoid the product being flattened;

Make sure that both ends are synchronized when the traction arm is pressed and relaxed; if not, adjust the unidirectional throttle valve on both cylinders;

Please make sure that the starting position of the tractor and cutting machine has been adjusted, and the direction of traction and cutting rotation are correct;

Please make sure that the following and pressing pressure of the cutting machine is appropriate; pay special attention to the cutting machine after the completion of the cutting action return speed should not be too fast to avoid impact on the rack;

The above contents must be checked in turn before the first boot to ensure boot successfully.
