1. Hydraulic connections are different hydraulic components (pumps, transmission lines, reversing valves, stop valves),
Hydraulic motors, hydraulic cylinders, and some auxiliary elements, such as level gauges, thermometers, pressure gauges, etc., are joined together to form a closed loop hydraulic system, which is a connecting function of an accessory.
2. The hydraulic connector can withstand high pressure, if the hydraulic tubing joints impact sand holes, small holes or pressure is too high can not afford so much pressure and blasting is quite large.
3. Hydraulic joints are divided into two major categories: hose joints, hard pipe joints
Each of these two categories is divided into several categories:
1) hose connector divided into integrated hose connectors, extruded hose connectors, InteriorLocking
Hose fittings, detachable hose couplings, etc.
2) hard pipe joint is also called transition joint. It is divided into DIN card sleeve type and metric thread joint,
Inch screw thread joint, thread joint, flange, welding joint mining etc.
4. Hydraulic joints are widely used in military, energy, petrochemical, power, ship, automobile and rail transportation,
In the hydraulic pipeline system of construction machinery, mining, metallurgy, steel works, ocean engineering, etc.
National standard GB1800.1-2009 will determine the standard tolerance level of size accuracy is divided into 18 grades, respectively using IT1, IT2,...... IT18 representation. From IT1 to IT18, the corresponding tolerance values increase sequentially, and the accuracy decreases.
The dimensional accuracy obtained by cutting is generally related to the equipment, tools and cutting conditions used. The higher the dimensional accuracy, the more complicated the process of the parts, the higher the processing costs. Therefore, in the design of parts, should ensure the use of parts under the premise of, as far as possible the use of lower dimensional accuracy.
