Information

Shandong Zhengxiang Industrial and Mining Equipment Co., Ltd. is a professional R & D, production, sales of copper sleeve, graphite copper sleeve, self-lubricating copper sleeve, copper sliding plate, copper worm gear, copper screw manufacturers, our company has perfect processing equipment, welcome to figure customized.

 

Crane is also called floating crane. As a harbor ship mainly used for loading and unloading of large cargo. There are lifting equipment on board, the boom has fixed and rotary. The lifting weight generally ranges from hundreds to thousands of tons. Crane ships are not normally self-propelled. It can also be used as a harbor engineering ship.

 

The crane support structure shall be provided with longitudinal and transverse supporting bulkheads or other effective supporting structures with sufficient strength and stiffness. The reinforced structure should be able to transfer stress effectively. The deck slab there shall be thickened according to the lifting capacity of the crane. Boom crane or fixed crane ship generally adopts single deck non-self-propelled (or low speed operation sailing, towing) box barge hull form. According to the lifting capacity, strength requirements and structural strengthening requirements of simplified crane, the full rotary crane ship can be designed as a double deck hull structure.

 

Crane copper sleeve generally uses aluminum bronze self-lubricating graphite copper sleeve, aluminum bronze content is generally not more than 11.5%, sometimes also add appropriate iron, nickel, manganese and other elements, in order to further improve the performance. Aluminum bronze can be strengthened by heat treatment, its strength is higher than tin bronze, high temperature oxidation resistance is also better.

 

Self-lubricating copper sleeve it has high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability and other characteristics, especially suitable for heavy load, low speed, reciprocating or swinging such as difficult to lubricate and form oil film occasions, also not afraid of water and other acid erosion and erosion. The majority of users generally reflect that Mosaic bearings not only save oil and energy, but also their working life is longer than ordinary plain bearings. At present, the products have been widely used in metallurgical continuous casting machine, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.

 

Aluminum bronze containing iron and manganese elements has high strength and wear resistance, after quenching and tempering can improve the hardness, has good high temperature corrosion resistance and oxidation resistance in the atmosphere, fresh water and seawater corrosion resistance is very good, machinability is acceptable, welding is not easy to fiber welding, hot pressure processing is good.

 

The crane shaft sleeve produced by our company adopts centrifugal casting method. Our company has complete metal casting equipment, such as sand mold, steel mold, large horizontal centrifuge, drum centrifuge and vertical centrifuge, providing sand mold casting, metal mold casting, centrifugal casting and other casting processes. Among them, centrifugal casting has the ability to produce large copper sleeve, nut down, wire down, also can be customized according to customer requirements of various specifications and materials of large copper sleeve, copper nut, copper tile, copper slide, copper worm gear, copper bell, copper pipe, zinc base alloy parts and other non-ferrous metal products, if necessary, welcome to the drawing consultation.
