Hydraulic system for industrial machinery

Advanced hydraulic technology for rubber vulcanization processes

Overview

Rubber possesses unique properties such as elasticity, wear resistance, and excellent air tightness. However, these same properties—particularly elasticity—make rubber processing challenging. Shaping rubber into specific finished products presents even greater difficulties. Consequently, rubber processing requires specialized equipment to increase plasticity and reduce elasticity, followed by semi-finished product processing, and finally restoring the plasticized semi-finished products to their original elastic state through a process known as vulcanization.

Vulcanization represents the final stage in the production of nearly all rubber products. Due to the diversity of vulcanization processes and the unique characteristics of various vulcanized products, a wide range of vulcanization equipment exists. Based on application, this equipment can be categorized into plate vulcanizers, drum vulcanizers, tire shaping vulcanizers, and more.

Rubber vulcanization process

Plate vulcanizers are primarily used for vulcanizing flat rubber products such as conveyor belts and transmission belts (commonly referred to as flat belts). They offer advantages including high pressure per unit area of hot plates, reliable operation, and minimal maintenance requirements. The primary functions of a plate vulcanizer are to provide the pressure and temperature required for vulcanization. Pressure is generated by the hydraulic system through hydraulic cylinders, while temperature is typically provided by a heating medium such as steam.

A common question in industrial maintenance is, "is hydraulic oil the same as transmission fluid"—an important consideration for proper system operation and maintenance. This distinction becomes particularly relevant when maintaining complex systems like the XLB1800×10000 plate vulcanizer.

This technical documentation focuses on the main hydraulic system of the XLB1800×10000 plate vulcanizer. The model designation follows GB/T12783-2000 standards, where:

  • X represents rubber machinery
  • L denotes a vulcanizer
  • B indicates a plate type
  • 1800×10000 specifies the plate dimensions

This documentation will detail the principles and characteristics of the hydraulic system that powers this specialized industrial equipment, highlighting its efficiency, precision, and reliability in rubber processing applications.

Working Principle of the Hydraulic System

The hydraulic system of the XLB1800×10000 plate vulcanizer is engineered for precision, efficiency, and reliability in demanding industrial environments. Figure 8-12 (conceptual representation shown below) illustrates the principle diagram of the main hydraulic system, which coordinates multiple components to deliver the precise pressure and movement required for rubber vulcanization.

The main unit of the plate vulcanizer derives its pressure during the vulcanization process from the plunger hydraulic cylinder (component 33). The rapid ascent of the plate is powered by a low-pressure, high-flow vane pump (component 10). Once the plate reaches its designated position, the vane pump ceases operation, and a variable displacement piston pump (component 5) engages to apply pressure. When the pressure reaches the preset value, the variable displacement piston pump stops, and the system enters a pressure-holding state.

When pressure drops to a predetermined level, a small-displacement variable piston pump (component 14) activates to compensate pressure, ensuring proper vulcanization of the rubber belt. Understanding fluid requirements is crucial here—many operators ask, "is hydraulic oil the same as transmission fluid" when maintaining these pumps, and using the correct fluid is vital for system longevity.

Detailed Operational Sequence

First Exhaust Cycle
  1. Solenoid valves 2YA, 3YA, 4YA, and 5YA are energized
  2. Hot plates rise rapidly
  3. Upon reaching the designated position, pressure in plunger hydraulic cylinder 33 reaches the low-pressure setpoint
  4. Pressure transmitter 25 sends a signal to activate variable piston pump 5
  5. Solenoid valve 1YA is energized,加压柱塞液压缸33
  6. System reaches high-pressure setpoint and maintains pressure for a specified duration
  7. Solenoid valve 18YA is energized, rapidly relieving pressure in plunger hydraulic cylinder 33
  8. Upper and lower hot plates separate by a predetermined distance

Following the first exhaust cycle, the process repeats for a second exhaust and pressure-holding phase. This dual exhaust process ensures that any air pockets within the rubber material are eliminated, which is critical for producing high-quality vulcanized products with uniform properties.

Vulcanization Process
  1. After completing two exhaust cycles, the system enters the vulcanization phase
  2. Solenoid valves 2YA, 3YA, 4YA, and 5YA are energized, causing hot plates to rise rapidly
  3. When pressure in plunger hydraulic cylinder 33 reaches the low-pressure setpoint, pressure transmitter 25 sends a signal
  4. Solenoid valve 1YA is energized, activating variable piston pump 5
  5. Pressure in plunger hydraulic cylinder 33 reaches the high-pressure setpoint
  6. All hydraulic pumps cease operation
  7. Plunger hydraulic cylinder 33 enters pressure-holding state

During the vulcanization phase, maintaining precise pressure is critical. When pressure in plunger hydraulic cylinder 33 drops to the pressure compensation setpoint, pressure transmitter 25 sends a signal to activate the pressure compensation hydraulic pump 14. Solenoid valve 6YA is energized, replenishing pressure in plunger hydraulic cylinder 33 to the high-pressure setpoint. This automatic pressure compensation ensures consistent curing conditions throughout the vulcanization cycle.

Mold Opening Sequence
  1. Upon completion of the vulcanization process, the system prepares for mold opening
  2. Solenoid valve 17YA is energized, opening pilot-operated check valve 28
  3. Hot plates descend to their initial position under their own weight
  4. The complete vulcanization cycle is finished

This sophisticated sequence of operations demonstrates the system's ability to precisely control pressure, movement, and timing—all critical factors in producing consistent, high-quality rubber products. Proper maintenance, including using the correct hydraulic fluids (remembering that the answer to "is hydraulic oil the same as transmission fluid" is generally no) ensures this complex system operates at peak efficiency for extended periods.
