Product Details
Crane pipe is a special equipment for fluid handling in petrochemical industry. Material selection of unloading crane pipe: low carbon steel, stainless steel, aluminum alloy, etc. sealing material of loading and unloading crane pipe: oil resistant nitrile rubber, fluororubber. The balance system of loading crane includes counterweight, torsion spring, compression spring, tension spring, lead screw, hydraulic and pneumatic balance, which can be operated with very small force. It uses the rotary joint to connect with the rigid pipe and elbow, so as to realize the movable equipment of liquid medium transmission between the train, truck tanker and trestle storage and transportation pipeline, so as to replace the old hose connection, which has the characteristics of high safety, flexibility and long service life. There are many kinds of crane pipe joints. From the point of view of convenience, the rotary joint must be more convenient and available. Therefore, from the market point of view, the use of crane pipe rotary joint is generally large.
(1) The swivel joint of the crane pipe is a spherical outer pipe. The oil-free bearing and the shell are installed together. The connection is tight, the rotation is free and the movement is flexible
(2) The installation accuracy is not high. The wear of spherical seal ring is small
(3) The sealing component of the swivel joint of the crane pipe has high sealing performance, and the wear of the outer cylinder can be observed
In addition, the rotary joint is directly installed to the outer tube or roller dryer of the crane. As an important part of the crane, the crane rotary joint with super high market demand is widely used. The crane is mainly composed of fixed, rotary, operating, balancing and other mechanisms and oil pipes.
Among them, the rotary mechanism (rotary joint) is meticulously made of forged steel or aluminum alloy. It is equipped with multiple ball bearings and stainless steel special sealing ring. It has flexible rotation, reliable sealing performance and long service life. The main components of floating plate in storage tank are prop, manhole device, oil measuring device, ventilation device, static conductive device, anti rotation device, peripheral sealing device, buoyancy element, framework (structural part), cover plate, fastener, etc.
