What Are The Common Causes Of The Plastic Granules Making Machine And How To Deal With It? Aug 11, 2017

What are the common causes of the plastic granules making machine and how to deal with it?
Familiar with the industry friends are aware of plastic granules making machine, electrical, instrument height of integration, automation and control level is very high. Therefore, in the actual operation will appear more difficult to diagnose the fault, resulting in processing time is too long, thus affecting the normal operation of the whole device, greatly reducing the economic efficiency of production. The author combined with the theoretical knowledge of the plastic granulation production process and the management experience of the actual production operation for more than ten years, the analysis and judgment of the common causes of the failure of the unit in operation, and the corresponding measures and methods are put forward to ensure the long Stable operation of the cycle. Hope to help everyone, thank you! The same time as
Failure reasons: In the plastic granules making machine, resulting in plastic granules making machine in the operation of the friction clutch disengagement, unit interlocking parking reasons can be divided into four categories:
(1) main motor system failure
1, the main motor torque is too high or too low; 2, the main motor speed is too low; 3, the main motor bearing temperature is too high; 4, the main motor winding temperature is too high; 5, the main motor water cooler inlet temperature is too high; 6, the main motor bearing lubricating oil pump outlet flow is too low; 7, the main motor bearing oil pump outlet pressure is too low; 8, the main motor water cooler water leakage is too high.
(2) Drive system failure
3, the friction clutch speed difference is too large; 4, the gear box lubricating oil pump outlet pressure is too low; 5, the gear box lubricating oil pump outlet oil temperature is too high; 3, the friction clutch clutch pressure is too high; 3, friction clutch speed difference is too large; High; 6, friction clutch internal failure and so on.
(3) plastic granules making machine screw process section failure
1, the throttle valve before and after the melt pressure is too high; 2, the head melt pressure is too high; 3, before and after the converter pressure difference is too large; 4, driving valve rotation failure.
(4) Underwater pelletizing system failure
1, the pellet motor winding temperature is too high; 2, pelletizer speed is too low; 3, pelletizer torque is too high; 4, particle water bypass automatic switching failure; 5, particle water pressure is too high or too low; , The pellet water flow is too low; 7, pelletizer clamping bolt is not tight; 8, granule chamber bypass water valve is not closed; 9, pelletizer hydraulic clamping pressure is too low; 10, 11, hydraulic cutter axial feed pressure is too low and so on.
In the above fault causes, there are more frequent frequency: the main motor system, the main motor torque is too high or too low; transmission system friction clutch failure; plastic granules making machine screw process section of the system of high melt pressure; Machine system failure and so on. The following will be a detailed analysis of these common causes of failure, given the corresponding solution.
plastic granules making machine feed speed and temperature changes in the level of the sound issued by the very different. plastic granules making machine to continue to explore in practice, to strive to keep the machine running the best state when the sound of the smallest. The main function of the brake system is: control and regulation of the main and auxiliary motor drag motor, output to meet the required speed and power, and coordination of the main and auxiliary work; detection and regulation of plastic machinery in the temperature, pressure, The entire unit of the control or automatic control.
Plastic control of the plastic granules making machine can be divided into two parts: drive control and temperature control, to achieve the extrusion process, including temperature, pressure, screw speed, screw cooling, barrel cooling, product cooling and so on.
As we all know, plastic granules making machine industry is also a high energy consumption, high pollution industries, in order to develop well, must take the green line. Today's granulator industry has gone through the advantages of low labor force and sacrifice the environment at the expense of the extensive stage of development, conform to the international trend of low-carbon economy, the industry is actively exploring the development path of energy conservation and environmental protection. This is not only the government at all levels need to further change the concept of things, but also need the majority of manufacturing enterprises need to further emancipate the mind, broaden their horizons, but also need to international strategic vision to deal with the development of the industry.
