Electric Use MPP Pipe Production Line 50mm - 250mm With Single Screw Extruder

Specification:

The production process of the MPP pipe is an extrusion molding process. First, the MPP raw material in the hopper enters the extruder by its own weight, and is heated and extruded in the extruder barrel, and fully plasticized from the extruder port. The die is extruded and enters the setting table. After the shaping, the pipe is passed through the tractor and cut by the cutting machine. The pipe is cut by the cutting machine and the pipe is inspected and put into storage. The corresponding fittings are produced by injection molding.
Pipe production process: MPP raw material → vacuum suction feeding → hopper storage → feeding → extrusion molding → cooling setting → traction → cutting → inspection → storage
Pipe production process: PP-R raw material → conveying and feeding → hopper storage → feeding → heating and melting → extrusion molding → cooling and setting → mold opening → inspection → storage.
Pipe extrusion parameters: (1) screw speed 5 ~ 38r / min (2) barrel temperature distribution 1 ~ 2 area 180 ~ 190 ° C 3 ~ 4 area 200 ~ 210 ° C mold temperature 200 ° C traction speed 2 ~ 20m / min pipe fittings Injection parameters: (1) barrel temperature distribution barrel rear 160 ~ 170 ° C barrel middle 200 ~ 230 ° C barrel front 180 ~ 200 ° C (2) nozzle 170 ~ 190 ° C (3) mold 40 ~ 80 ° CPP The defective products produced in the -R pipe production process can be reused after being crushed, which improves the utilization rate of raw materials, reduces production costs, and improves economic benefits.

Main technical parameter:

Maintenance method

1. After 500 hours of use, there will be iron scraps or other impurities from the gears in the gearbox. Therefore, the gears should be cleaned and the gearbox oil should be replaced at the same time.

2. After a period of use, perform a thorough inspection of the extruder and check the tightness of all screws.

3. If the main power supply and heating are stopped suddenly during production, when the power supply is restored, the barrels must be reheated to the specified temperature and kept warm for a period of time before the extruder can be started.

4. If the steering fullness of the meter and the pointer is found, check whether the contact of the edge such as the thermocouple is good.
