How do I determine the pressing dimension for pressing a hydraulic hose? Now online, you can find our latest YouTube video on the subject of “hydraulic hose pressing” at https://buff.ly/3iI548W.
In this video, we will show you what is involved in the pressing dimension when pressing a hydraulic hose. The pressing dimensions depend on the hydraulic hose used and the hydraulic hose fittings.
In this example we use a 2SC hose, size DN6. The pressing dimension for this hose is 16.8mm, so we use the next smaller size 16 jaw set for the hydraulic hose press and adjust the pressing dimension with the micrometer screw to an additional 0.8mm, so that we get a pressing dimension of 16.8mm.
Determination of the pressing dimension of a hydraulic hose
Hydraulic hoses are critical components in hydraulic systems because they allow fluid to flow and ensure that the system functions properly. The crimping dimension of a hydraulic hose refers to the proper connection and crimping of the hose to the associated fittings to ensure reliable and safe performance.
Definition of the pressing dimension
The crimping dimension of a hydraulic hose refers to the proper crimping of the hose with the appropriate fittings to make a secure connection. It is important to use the correct pressing dimension to avoid leaks and damage to the hose.
Why is the pressing dimension important?
The pressing dimension is important to ensure a safe and reliable connection between the hydraulic hose and the fittings. If the pressing dimension is not correct, leaking connections may occur, resulting in loss of performance or even serious damage to the hydraulic system.
How is the pressing dimension measured?
The crimping dimension of a hydraulic hose is determined with the aid of a hose crimper. The hose crimper allows precise crimping of the hose to the fittings to create a secure connection. By using a hose crimper, the crimping dimension can be accurately measured and adjusted to ensure optimum performance of the hydraulic hose.
Functionality of a hose press
A hose crimper is a special device designed to determine the crimping dimension of hydraulic hoses and ensure proper crimping. The hose press consists of a device for holding the hose and a hydraulic press that compresses the hose with the fittings.
Types hose presses
There are different types of hose presses, including manual hose presses and automatic hose presses. Manual hose crimpers are operated by hand and require physical strength to crimp the hose. Automatic tube presses, on the other hand, are electrically or hydraulically operated and offer higher performance and accuracy in pressing.
Advantages of using a hose press
The use of a hose press offers several advantages. First, it allows precise crimping of the hose to the fittings to create a secure connection. Secondly, it saves time and labor compared to manual pressing. Third, it ensures reliable and safe performance of the hydraulic hose.
Pressing process with a manual hose press
When using a manual hose press, the pressing process is performed by pressing the lever or handles of the hose press. This requires physical strength to crimp the hose to the fittings. After the pressing process, the pressing dimension is checked to ensure that it complies with the specifications.
Checking the grouting with a test mandrel
After pressing the hydraulic hose, the quality of the connection can be checked with a test mandrel. The test mandrel is inserted into the joint and the pressure in the hose is increased. If the joint has been properly grouted, it will withstand the pressure and there will be no leakage. However, if leaks occur, the grouting must be checked again and corrected if necessary.
What problems can occur during grouting?
Leaky connections
One of the most common problems with hydraulic hose crimping is leaking connections. Leaky connections can result in loss of power, contamination of the environment, and safety hazards. It is important to check the grouting carefully to identify and fix leaks.
Detect faulty grouting
It is important to identify and correct faulty grouting as it can affect the performance and safety of the hydraulic system. Signs of faulty grouting include leaks, loose fittings, or an unsafe connection. Regular inspections and maintenance work allow faulty grouting to be detected and rectified in good time.
Avoidance of grouting errors
To avoid pressing errors, it is important to use the right tools, such as a hose press, and to carefully monitor the pressing dimension. In addition, it is important to receive training and instruction on proper grouting and to conduct regular inspections to ensure that joints are properly grouted.
When should a hydraulic hose be re-grouted?
Relevant factors for repressing
There are several relevant factors that should be considered to determine when a hydraulic hose should be re-grouted. These include aging of the hose, external damage, leaks, or problems with the performance of the hydraulic system. If one or more of these factors occur, the hydraulic hose should be checked for crimping and re-crimped if necessary.
Signs of worn grouting
Signs of worn compression include leaks, loose fittings, or an insecure connection between the hydraulic hose and fittings. When these signs appear, it is important to check the hose for crimping and, if necessary, repress it to ensure the performance and safety of the hydraulic system.
Maintenance and servicing of hydraulic hoses
To ensure reliable performance of hydraulic hoses, regular maintenance and servicing is required. This includes checking crimps, replacing worn or damaged hoses, and performing inspections to identify and correct potential problems early. Proper maintenance and servicing can optimize the life and performance of hydraulic hoses.
