Flat Face Hydraulic Quick Coupling

Product introduction

Hydraulic quick connectors are precision components used in hydraulic systems to quickly connect and disconnect pipelines. It requires no tools and can be operated by one person with bare hands, which can greatly improve the efficiency of equipment maintenance and replacement, and reduce downtime and media leakage.

 

The product is manufactured using high-quality materials and precision technology, has excellent sealing performance, can withstand high-pressure working conditions, and effectively reduces fluid pressure loss. Its built-in safety locking mechanism ensures that it will not accidentally disconnect under high pressure after connection, ensuring safe operation.

 

It is widely used in construction machinery, agricultural equipment, mining machinery and various industrial hydraulic systems. It is an ideal component to improve work efficiency and automation level.

 

Product features

1. Quick operation and convenient connection: With one-hand holding, one-button or push-pull design, the pipeline can be connected or disconnected in seconds without any tools, which greatly improves the efficiency of equipment maintenance and production line replacement.

 

2. Reliable sealing and anti-leakage: Using high-quality O-ring, flat seal or ball valve sealing structure, a tight seal is automatically formed at the moment of connection, which can effectively prevent the leakage of hydraulic oil under working pressure (even under high-pressure impact), keeping the system clean and environmentally safe.

 

3. Low pressure loss and efficient circulation: The internal flow channel is optimized and designed with large diameter and small flow resistance, which can minimize the pressure loss and energy consumption of the hydraulic system and ensure sufficient power for the actuator.

 

4. Safe locking, strong and durable: equipped with automatic safety locking mechanism (such as steel ball lock sleeve) to ensure that the joint will not accidentally loosen under vibration and high pressure conditions, ensuring the safety of personnel and equipment. At the same time, the sturdy metal shell makes it impact-resistant, wear-resistant, and has a long service life.

 

5. Complete range and strong compatibility: Provides a variety of specifications, diameters, pressure levels and interface forms (such as threads, flanges), and can be interchanged with standard joints of various brands at home and abroad to meet the compatibility needs of different equipment and complex working conditions.

 

Product application

1. Construction machinery: This is the most typical application field. Used on excavators, loaders, cranes, concrete pump trucks and other equipment to quickly connect and disconnect buckets, breakers, hydraulic shears and other attachments, greatly improving work efficiency and equipment utilization.

2. Agricultural machinery: widely used in tractors, combine harvesters and other equipment, used to quickly connect and switch agricultural tools such as plows, seeders, harvesting tables, etc., to achieve rapid conversion of different operating links.

3. Industrial manufacturing and equipment: used for hydraulic system maintenance, debugging and troubleshooting of industrial equipment such as injection molding machines, presses, machine tools, etc. It is also often used for quick replacement of tooling fixtures in production lines.

4. Mining and forestry machinery: Provide reliable and durable quick connection solutions for mining drills, loggers and other equipment under harsh working conditions, withstanding high pressure and severe vibration.

5. Testing and diagnosis: used to connect pressure gauges, sensors and other testing equipment to facilitate online testing and fault diagnosis of the hydraulic system without interrupting system operation or draining hydraulic oil.

6. Transportation and emergency rescue: used for hydraulic pipeline connections in sanitation vehicles, tow trucks, firefighting and rescue equipment to achieve rapid deployment and operation.

 

FAQ

Q: What is the reason for leakage after the joint is connected?

A: Seal damage: O-ring or sealing plane wear, cutting, and aging are the most common causes and need to be replaced regularly. Dirt intrusion: If it is not cleaned before connection, impurities are stuck on the sealing surface, resulting in loose sealing. Be sure to keep the joints clean. The joint is not fully connected: the lock sleeve is not pushed in place and the safety lock is not engaged, resulting in the internal valve not being fully opened. The joint body is damaged: The thread or sealing surface is bumped or damaged.

 

Q: I feel a lot of resistance when connecting or cannot connect completely. What should I do?

A: Check the male and female joint models: Confirm that the models, diameters and pressure levels of the two match and are interchangeable. Check the sealing ring: Whether the sealing ring of the female joint is improperly installed or expanded and deformed. Release residual pressure: There may be residual pressure in the pipeline, causing the valve to fail to open. Please use a joint with a pressure relief function or relieve the pressure in a safe manner. Check the internal valve core: Whether the valve core is stuck or damaged.

 

Q: How to correctly choose hydraulic quick connectors?

A: Core parameters: Confirm the system’s working pressure, flow rate (determines the diameter), oil type and interface thread standard. Functional requirements: Consider whether unilateral or bilateral cutoffs, pressure relief functions, safety locking types, etc. are required. Application environment: Consider the cleanliness of the environment, the presence of corrosion, vibration and other harsh working conditions, and select appropriate materials and surface treatments.
