3. Core Functional Description

3.1 Precise Electro-Hydraulic Brake Control

BK-DC-05 electro-hydraulic proportional valves and PSZ75B actuating mechanisms form an intelligent hydraulic control unit, solving the pain point of unstable braking torque output caused by traditional mechanical control deviation. Matched TK brake valves and globe valves ensure accurate hydraulic circuit switching, maintaining consistent braking response under variable heavy-load working conditions.

3.2 Real-Time Operating Condition Monitoring

YW2-150 oil level temperature gauges and YN60-III 0-16MPa pressure gauges achieve real-time monitoring of hydraulic system operating parameters. This configuration eliminates hidden faults such as high-temperature oil degradation and insufficient system pressure that cannot be detected in time, effectively improving overall operational safety of hydraulic systems.

3.3 Reliable Sealing & Explosion-Proof Protection

BK-SR and YX series sealing rings and guide bands build full-circuit hydraulic sealing protection to prevent medium leakage and dust invasion. EXX explosion-proof electric boxes meet field hazardous environment safety standards, avoiding electrical safety risks caused by spark leakage during equipment operation.

4. Structural Characteristics

All accessories adopt modular standardized structural design with unified industrial assembly tolerances, supporting rapid on-site disassembly and replacement without secondary calibration. Core caliper cylinder and piston components adopt high-pressure resistant integral forging technology, with strong deformation resistance under long-term hydraulic impact. Copper bush and guide band structures reduce internal friction loss, while adjusting screws and baffle plates support precise gap calibration. Explosion-proof electrical configuration and high-strength sealing structure adapt to extreme oilfield working conditions, greatly improving system operational stability and safety.

5. Applicable Working Conditions

This series of electro-hydraulic brake components is applicable to onshore oilfield drilling rigs, workover equipment and heavy hoisting machinery electro-hydraulic control and braking systems. It stably adapts to harsh open-air working environments with ambient temperatures ranging from -25℃ to 70℃, high dust concentration and flammable gas hazards, maintaining stable hydraulic control, braking performance and electrical safety under long-term intermittent heavy-load cyclic operation.

6. On-site Maintenance Suggestions (Engineer Practical Experience)

Summarized from frontline oilfield maintenance practice, hydraulic cylinder sealing parts and copper bushes require inspection every 3 months and full replacement every 8 months to avoid friction attenuation and leakage. Pressure and temperature monitoring instruments need regular calibration to ensure accurate data feedback. Explosion-proof electrical boxes and valve groups should be cleaned and inspected periodically to prevent dust accumulation affecting control performance. Mismatched fastener installation is strictly prohibited to avoid structural gap deviation. Standardized maintenance can increase the continuous stable working duration of matched equipment by 3000 working hours compared with irregular maintenance modes.
