straw rope production line fibrilated filament extruder melt pump

In the production process of straw rope, the polymer melt pump plays a vital role as one of the core equipment for handling raw fiber filaments. This pump is designed to uniformly and stably convey plastic, rubber, or specific bio-based materials (such as those used in the production of straw rope) in a high-temperature molten state into the extruder barrel through its unique rotating or reciprocating motion mechanism. This process ensures the dual enhancement of both the final quality and production efficiency of the straw rope.

1. Structure composition and working principle

The extruder melt pump comprises key components such as the pump body, precision-machined rotors, high-efficiency seals, durable bearings, and precise transmission devices. Its working principle relies on the efficient operation of rotating rotors, which effectively draw molten materials into the pump chamber. Subsequently, through the precisely controlled gap between the stator and rotor, the materials are continuously and uniformly conveyed to the outlet end. During this process, the melt pump employs a sophisticated pressure and temperature control system to ensure that the materials maintain their ideal molten state throughout the conveying process, thereby guaranteeing their uniformity and stability.

2. Detailed installation steps

Preparation Stage: Firstly, conduct a thorough inspection of all pump components to ensure no damage or missing parts. Subsequently, prepare a sturdy and level steel frame platform as the foundation for installing the melt pump.

Installing the Pump Body: Utilize lifting eye bolts (for large pump bodies) or professional lifting tools to hoist the melt pump smoothly and accurately place it on the steel frame platform. Adjust the position of the pump body to ensure that its concentricity with the motor drive shaft meets design requirements, and securely fasten it with anchor bolts.

Connecting the Transmission Device: Use a universal coupling to precisely align the melt pump's shaft with the reducer, strictly controlling installation errors to ensure transmission efficiency and stability. Subsequently, complete the power and control system connections between the motor, reducer, and pump body.

Installing Sensors: Precisely install pressure sensors and temperature sensors at the inlet and outlet of the pump body to ensure that these critical monitoring devices accurately reflect the operating status of the melt pump, while also ensuring their installation is firm and reliable.

Inspection and Debugging: Thoroughly inspect all connections for tightness and absence of leaks. Then, start the motor for a no-load test run to observe the pump's operation. Gradually adjust to normal working pressure and speed, conduct a load test run, and ensure that the equipment's performance meets standards.

3. Usage and Maintenance Guide

Usage Precautions:

Keep a close eye on the melt pump's operating temperature and pressure changes to ensure stable operation within the rated range.

Regularly check the sealing performance to prevent material leakage that could cause contamination or loss.

Regularly inspect the lubrication status of the transmission devices and bearings, and promptly replenish or replace lubricant to ensure smooth equipment operation.

Maintenance:

Regularly clean dust and dirt from inside and outside the melt pump to maintain cleanliness.

Regularly inspect the wear conditions of key components such as the pump body, rotors, and seals, and promptly replace heavily worn parts.

Regularly check the operating status of electrical connections and control systems to ensure safe and efficient equipment operation.

As a crucial piece of equipment that ensures the quality and output of straw rope production, the extruder melt pump for raw fiber filaments in the straw rope production line is undeniably important. By following reasonable installation steps, correct usage methods, and regular maintenance measures, not only can the stable operation and extended service life of the melt pump be ensured, but also its performance and reliability can be further enhanced with technological advancements and market development, providing more solid support and assurance for the straw rope production industry.
