In a fiercely competitive market, choosing a product undoubtedly requires starting from its structure, purpose, characteristics, performance, and other aspects. Therefore, when choosing a high-pressure steel wire braided rubber hose assembly product, corresponding skills should also be mastered to avoid corresponding problems. In the process of selecting hydraulic pipe joints, various factors such as working pressure, working temperature, interface size, applicable pipe inner and outer diameters, ease of installation, and economy need to be considered.

1、 Joint crimping

1. High pressure oil pipe and joint model

Select the appropriate hose model and joint model based on the actual list of high-pressure hydraulic hoses needed.

2. Determine the length of the feeding hose

Length of feeding hose: The total length of the hose includes the length of the joints at both ends of the hose, and the actual length should be subtracted from the length of the joints at both ends.

3. Cutting pipes

The high-pressure oil pipe should be cut to the design length according to its required specifications, and the cutting section should be vertical, flat, and not damage the steel wire layer.

4. Peel off the outer adhesive layer

For rubber hoses that require stripping of the outer layer, the length of the outer layer at both ends of the hose should be stripped according to the size of the high-pressure steel wire braided rubber hose joint and sheath, and the position should be marked with markers. After stripping, the steel wire must not be damaged, the steel wire must not be loose, and the inner wall must not be damaged.

5. Mark the position of the inserted connector

Place the rubber hose next to the pipe joint and mark the insertion depth.

6. Insert connector

Apply a small amount of hydraulic oil or lubricating oil to the core of the joint, and insert the pipe into the joint until the marking line is flush with the end of the sleeve.

7. Angle setting

The spatial angle of the high-pressure steel wire braided rubber hose assembly only needs to be noted when the pipe joints at both ends of the hose are elbows and not in the same direction. The angle of the hose assembly is the angle required to rotate the distal elbow clockwise to coincide with the proximal elbow direction

8. Clamp rubber hose component

Select the appropriate crimping mold and install it on the crimping machine, and correctly place the pipe joint to be crimped into the crimping mold. Press the crimping switch until the mold is fully crimped onto the pipe joint and run to the position specified in the machine's built-in parameter table. Release the crimping mold, take out the hose assembly, check whether the crimping marks on the crimping surface are uniform, and use a vernier caliper to measure whether the crimping size is within the crimping size range.

9. Clean and seal

The hydraulic system needs to achieve the corresponding cleanliness, and quick and convenient pressure cleaning equipment should be used to clean the hose components. The device uses kerosene to flush the inner wall of the rubber hose assembly, then uses high-pressure gas to blow out the cleaning solution, and protects the cleaned high-pressure steel wire braided rubber hose with a sealing cap or bag.

10. Pressure detection

The sampling pressure test of the rubber hose needs to be conducted on a pressure test bench. Pressurize the hose assembly to twice the predetermined working pressure and maintain this pressure for 30-60 seconds without any leakage.

2、 Where can the crimping position of the joint effectively prevent it from coming off?

If the blasting pressure is greater than 4 times the standard working pressure, it is considered a qualified rubber hose. If an explosion occurs at the crimping point, the main reason is that the rubber hose and the joint have not reached a suitable fit. Improvement should mainly focus on the selection of joints and crimping. The compression degree or material of the joint core needs to be improved. If the joint cannot be replaced, it is possible to try reducing the crimping amount without losing the head, in order to avoid damaging the rubber hose steel wire due to excessive crimping.

3、 Purpose:

Used for conveying fluids in hydraulic supports, oilfield development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems in various industrial sectors. Petroleum based and water-based liquids, as well as liquid transportation pipelines.

The high-pressure steel wire braided rubber hose is made of special synthetic rubber, which has excellent oil resistance, heat resistance, and aging resistance. In addition, understanding its basic characteristics in advance can lead to the purchase of suitable products, and it should be clear that the hose has high pressure and excellent pulse performance. A hydraulic joint is a connecting component that connects hydraulic pipelines with hydraulic pipelines, or pipelines with hydraulic components. In order to ensure compatibility with other components and leak free sealing, the terminal of the hydraulic hose joint needs to be designed according to the universal interface standard, and the main function of the tail end is to ensure long-term sealing at the connection between the joint and the hose.
