2000T FRP Cooling Tower Fan Stack Hydraulic Press

A fiberglass cooling tower fan stack is a ventilation device used in cooling towers, primarily to guide airflow through the cooling tower and promote heat dissipation. It is typically made of fiberglass and resin and is lightweight, durable, and corrosion-resistant. Its production uses a compression molding process, in which a hydraulic press, in conjunction with a mold, forms the product in a single operation.

Fiberglass cooling tower fan stack molding hydraulic presses are available in various configurations, including three-beam, four-column, and frame types. Depending on the fiberglass fan stack’s specifications and dimensions, commonly used hydraulic presses include 1500-, 1800-, 2000-, 3000-, and 4000-ton models.

This article mainly introduces the PDH 2000-ton FRP cooling tower fan stack forming hydraulic press. It uses a three-beam, four-column structure, with the three beams welded and heat-treated. The machine possesses sufficient rigidity and strength, a spacious operating area, and facilitates observation and mold installation and adjustment from all four sides.

The overall structure is simple and aesthetically pleasing. The hydraulic system integrates a cartridge system with proportional control valves, delivering high flow rate, high synchronization accuracy, and strong resistance to eccentric loads. It also features a simple, compact structure, sensitive and reliable operation, and support for fault diagnosis and troubleshooting. The machine’s power system is mounted at the top, reducing its footprint. Safety guardrails are installed around the upper beam, and a ladder is provided for easy installation and maintenance.

Our 2000-ton hydraulic press for FRP cooling tower fan stack molding uses a PLC control system to precisely regulate pressure, speed, and displacement, ensuring high-quality fiberglass cooling tower fan casings and production efficiency. This series of presses is primarily used for the compression molding of thermosetting and thermoplastic composite materials, including DMC, SMC, BMC, GMT, LFT-D, and FRP fiber-reinforced plastics.

Hydraulic Press Molding Process Workflow:

Ram rapid descent — Ram slow descent and pressurization — Ram pressure holding — Pressure release and rapid return — Ejector cylinder retraction — Retraction stop (manual workpiece removal) — Ejector cylinder extends for loading — Two-hand button activation to start the next cycle.

Main Features of the 2000-ton FRP Cooling Tower Fan Stack Hydraulic Press:

1. The hydraulic control adopts an integrated cartridge valve system, ensuring stable operation, long service life, and reduced hydraulic shock, minimizing connecting pipelines and leakage points.
2. The hydraulic press for molding FRP cooling tower fan casings features a computer-optimized structural design, a three-beam, four-column structure, making it simple, economical, and practical.
3. A separate electrical control system ensures stable operation, intuitive actions, and convenient maintenance.
5. Through the control panel, two operating modes—constant stroke and constant pressure—can be selected, and it also features functions such as prolonged pressure holding.
6. The working pressure of the slider, the range of fast downward movement under no load, and the slow working stroke can all be adjusted according to work requirements. The electrical control system is stable, the actions are intuitive, and maintenance is convenient.
7. The power mechanism and electrical system are centrally arranged, using centralized button control, allowing for adjustment and semi-automatic (manual or automatic material feeding) operation modes.
8. The working pressure, pressing speed, high-pressure downward movement, no-load fast downward movement, and ejection stroke of the fiberglass cooling tower fan casing hydraulic press can be adjusted according to the pressing process requirements of different products using pressure sensors, micro-regulating valves, inductive sensors, and displacement sensors. The hydraulic press uses a PLC and touchscreen to adjust force, time, and stroke parameters, ensuring product quality and high consistency.
9. It adopts a four-column cylinder-driven slider structure and features a fast-moving workbench driven by a hydraulic cylinder. An ejection device located outside the four columns works in conjunction with the moving workbench to achieve mold change and product removal outside the machine.

Advantages of the PDH 2000-ton FRP Cooling Tower Fan Stack Forming Hydraulic Press:

• The slider of the composite material molding hydraulic press has a high idle speed, effectively preventing premature curing of the molding material after it enters the mold.
• The slider speed and pressure can be adjusted arbitrarily within the specified parameter range, enabling a controllable pre-pressing process that improves material flow in the mold and reduces pressing time.
• The fiberglass cooling tower fan stack forming press features an automatic degassing function during pressing, and the slider return stroke has a micro-opening function that allows the molded product to slowly separate from the mold after forming, preventing tearing and damage.
• This equipment also features a light-curtain safety device and a hydraulic locking device to prevent the slider from slipping during mold installation.
• The hydraulic system is equipped with two sets of in-mold core pulling control systems and a pre-installed in-mold ejection control system, which can add functions such as multi-point ejection and air blowing.
