Glue Pump Control System Selection

 

Based on the customer's requirements for a glue pump control system, considering the glue viscosity, flow distribution, time control, temperature and pressure range, and electrical requirements, we recommend a solution consisting of 1.2cc and 0.6cc magnetic drive pumps with a 400W servo motor and a PLC control cabinet. The detailed analysis is as follows:

 

I. Core Requirements Analysis

 

Glue Characteristics: Glue viscosity is 11,000 cp, a high-viscosity medium. Wear- and corrosion-resistant pump materials are required to prevent clogging and leakage.

Flow and Time Control:

Glue A: 30 ml/min (0.5 ml/s)

Glue B: 60 ml/min (1 ml/s)

Dispensing Time: Mixing within 20 seconds. Precise control of pump start/stop and flow rate ratio is required.

Temperature and Pressure:

Temperature: 10-30°C (room temperature range). No special heating or cooling equipment is required.

Pressure: 1-4 bar (medium-low pressure range). The pump must meet pressure stability requirements. Electrical Requirements: 220V single-phase power; a drive device compatible with this voltage must be selected.

 

II. Recommended Solution Analysis

 

Pump Type Selection: 1.2cc and 0.6cc Magnetic Drive Pumps

Advantages of Magnetic Drive Pumps:

Leak-Free: Suitable for viscous media such as glue, eliminating the risk of shaft seal leakage.

Corrosion Resistance: The pump body can be made of either fluoroplastic or stainless steel to accommodate the chemical properties of the glue.

Abrasion Resistance: High-viscosity glues can easily wear the pump body. Magnetic drive pumps have a simple structure and low maintenance costs.

 

Displacement Matching:

 

1.2cc pump for glue B (60ml/min): 1.2cc/rev × 50 rev/min = 60ml/min (assuming a 50 rpm pump speed; actual speed will depend on motor speed).

0.6cc pump for glue A (30ml/min): 0.6cc/rev × 50 rev/min = 30ml/min. Drive: 400W servo motor

 

Servo motor advantages:

 

Precise control: PLC-controlled speed adjustment enables precise flow ratio distribution (e.g., A:B = 1:2).

 

Quick response: Starts, stops, and flow adjustments are completed within 20 seconds, meeting time requirements.

 

Energy efficiency: 400W power adapts to the load requirements of 1.2cc and 0.6cc pumps, eliminating energy waste.

 

Control system: PLC control cabinet

 

Functions:

Flow ratio control: The flow ratio of glue A and glue B (1:2) can be set via PLC programming.

 

Time control: Distribution is completed within 20 seconds, and the PLC can set timed start and stop times.

 

Pressure monitoring: An integrated pressure sensor provides real-time feedback on pump outlet pressure (1-4 bar).

 

Fault alarms: Overload, undervoltage, and idling protection functions ensure stable system operation.

 

Electrical compatibility: Supports 220V single-phase input to adapt to customer site conditions.

 

III. Solution Advantages Summary

Precise Distribution: Servo motors + PLC achieve precise control of the A/B glue flow ratio and timing.

Leak-Free Design: The magnetic pump prevents glue leaks and is suitable for high-viscosity media.

Stable and Reliable: The PLC control cabinet provides multiple protections and is suitable for industrial environments.

Energy-Saving and High-Efficiency: The 400W servo motor matches the pump load, reducing operating costs.
