HYDRAULIC HOSE CRİMPİNG MACHİNE

A hydraulic hose crimping machine is a device that is used to crimp or secure the end of a hydraulic hose. This is typically done to create a tight seal on the hose, ensuring that the hydraulic fluid stays contained and doesn't leak out. The machine works by using a hydraulic piston to apply pressure to the end of the hose, which causes it to deform and create a tight seal around the fitting that is attached to the hose. This type of machine is commonly used in the construction, agriculture, and manufacturing industries, where hydraulic hoses are widely used.

Hydraulic hose can be manufactured with the Hydraulic Hose Press. In order to manufacture hydraulic hoses, we need to understand the criteria such as hydraulic hose selection, hydraulic hose press selection and hose coupling selection.

HYDRAULIC HOSE SELECTION

First of all, it is necessary to determine the electrical conductivity in the environment where the hydraulic hose will be used. In some applications, hydraulic hoses are required not to conduct electricity, and in some applications, it is desired that the static electricity generated on the hose should be transmitted. Since this choice directly affects human life, it should never be forgotten and its determination should be made in such a way that there is no question mark.
While determining the Hydraulic Hose, it must be determined whether the maximum working pressure of the system is suitable for the working pressure of the selected hose. It should not be forgotten that this criterion directly affects human life.
As the structure of the suction line hoses and the pressure line hoses are different as stated in the product introduction, it should be determined whether the selected hydraulic hose will be used in the pressure line or the suction line. It should not be forgotten that the wrong choice to be made here will cause very serious malfunctions in the system elements.
It should be determined that the operating temperature of the selected hydraulic hose is suitable for the temperature of the fluid to be used and the ambient temperature. A mistake to be made here may cause a fire in the facility or cost human life. If necessary, heat protectors such as Glass Fiber should be placed on the hose.
If the selected Hydraulic Hoses are used in gas systems, the outer surfaces of the hoses should be perforated, because the gas passes through the layers more easily than the liquid. Therefore, balloons form on the hose, and if the gas used is explosive, human life is endangered due to the risk of explosion.
The diameter of the selected Hydraulic Hose should be determined very well, otherwise the equipment used in the system will be damaged due to excess or insufficient flow or operate with low efficiency.
The route of the hose should be determined very well in order not to cause confusion in the system.
In order for the Hydraulic Hose with Union to be healthy, it is essential that the Unions and the Hoses are compatible with each other.
Mechanical loads in the system directly affect the life of the hose. Therefore, when choosing the hose, it is necessary to consider the point as well as other criteria.
The hose must always be protected against the effects of shear and friction.
The length of the hose should be carefully determined. Long hose causes friction, sprains and complexity. A short hose shortens the life of the hose.

PRESSING HYDRAULIC HOSE FITTINGS

Before pressing, the dimensions of all selected materials (Hose, Socket and Unions) should be checked.
Hoses and Heads that are not suitable for each other should never be used together.
The mold size and settings of the machine on which the pressing will be made should be checked.
Old materials should never be reused. (Removing and pressing the unions again or pressing the new union to the old hose)
Since the hose pressing process directly affects human life in many cases, the people who carry out the pressing process should consider what kind of troubles may arise from the shortest mistake to be made and pay that much attention to the pressing process.
Errors that can be made in the pressing process are as follows;
1. Delivery of the Hydraulic Hose with Couplings without Pressing the Unions to the Hose

2. Miscalculation of the Pressing Size or incorrectly reading from the table and pressing

3. Pressing the pressing process in the right size but with the wrong mold

4. Performing the Pressing Process without sufficiently inserting the Unions into the Hose.

5. Defects that may occur due to the Pressing of Elbow or Twisted Special Couplings due to the Collision of the Press Jaws.

6. During the pressing process, a part of the socket is out of the mold.

SELECTING THE RIGHT HOSE OR PIPE DIAMETER

The pump suction line must be larger than the pipe in the discharge line.
The pipeline from the tank to the pump should be kept as short as possible.
Elbows or similar elements should be avoided at the entrances to the pump. Otherwise, the pump will overheat, which may damage the pump and other components.
When calculating the suction line, the Flow Rate value between V suction=0.8-1 m/sec is taken.
The pump pressure line should be chosen with a smaller diameter compared to the suction and return lines. Otherwise, we cannot get the desired pressure from the pump. When calculating the discharge line, the flow velocity value between V discharge=5-6 m/sec is taken.
Like the suction line, the pump return line should be chosen larger than the pressure line. Otherwise, restricted passages in the return lines will cause the pressure to rise and the power to be wasted unnecessarily. When calculating the return line
V rotation=2-4 m/sec Flow velocity value is taken.
