Classification & Marking Method of DME Hydraulic Hose Fittings
In the industrial fluid transmission system, DME hose connectors play a crucial role. Having a clear understanding of the types of these fittings and the standardized marking methods is essential for ensuring the efficient operation and the safety and stability of the system.
The Cruciality of Hydraulic Connectors
Hydraulic hose assemblies are widely used in numerous fields. Regardless of the harsh working environments they are in, they shoulder the important task of conveying fluids under extreme pressure and providing power for equipment operation. To ensure the safe and efficient operation of the system, hydraulic hose assemblies must be equipped with hoses that can meet the application pressure requirements and flow rates, as well as suitable hose fittings. At the same time, the installation of the fittings onto the hoses must be precise.
The DME&JDE Group has always attached great importance to research and development investment and technological innovation. Relying on its profound technical accumulation and continuous exploration, the hose assemblies produced by the group not only comprehensively exceed industry standards but also frequently surpass customers' expectations with their excellent quality and performance. We actively expand our global cooperation network and collaborate with professional partners around the world, aiming to quickly customize OEM fluid solutions for hydraulic hoses and fittings for customers, and assist customers in various industries in achieving efficient and reliable fluid transmission under complex working conditions.
As a crucial connecting component in the hydraulic system, the hose fitting shoulders the important task of orderly connecting various hydraulic components, enabling these components to jointly form a closed-loop hydraulic system and ensuring the stable operation and smooth power transmission of the entire system.
Hose fittings come in a variety of types, mainly including Crimp-type Hose Fittings, Detachable Hose Fittings, Snap-lock Hose Fittings, etc. Among them, crimp-type hose fittings are the most widely used in hose assemblies. Next, taking our DME&JDE brand fittings and hoses as examples, we will introduce the relevant details of crimp-type hose fittings to you with emphasis.
DME Crimping Hose Fittings
1.1 DME Crimping Hose Fittings
The DME crimp-type fitting is mainly composed of parts such as the fitting core, the outer sleeve (the nut is an optional part). During assembly, first assemble the fitting core, the hose and the outer sleeve. Then, under the uniform extrusion of the eight-petal crimping module of the crimping machine, the fitting and the hose will undergo a certain degree of plastic deformation, thus closely combining into a whole. In order to give full play to the performance of this type of DME fitting, we recommend using our "Super Shield" series hoses such as EN856 4SP/4SH in combination. The two have an excellent matching degree, which can significantly improve the reliability and stability of the hydraulic system.
The crimping hose fitting is divided into two kinds: one piece and split.
1.2 The Crimping Process of JDE Hoses and DME Hose Fittings
In the production process, the outer rubber at the crimping positions such as the end of the JDE hose should be stripped first to expose the steel wire layer, ensuring that the steel wires are not damaged. Subsequently, measure the outer diameter and inner diameter of the steel wire layer of the hose, group them accordingly, and calculate the crimping parameters accurately. During the assembly, first insert the hose into the outer sleeve, then insert the fitting core into the hose. Finally, carry out the crimping operation on the crimping surface of the hose fitting according to the crimping parameters corresponding to the hose groups.
1.3 JDE hose crimping form and characteristics
The selection of the crimping form of the hose mainly depends on the type of the hose, the dimensions of the inner rubber layer and the outer rubber layer, as well as the actual applied pressure-bearing environment of the hose assembly. There are mainly three types of crimping forms: crimping without skiving, crimping with the outer rubber layer skived off, and crimping with both the inner and outer rubber layers skived off.
