Analysis Of The Function Of The Pump Sleeve
The bearing bush of Solid-Liquid Mixing Pump is equivalent to the outer ring of the sliding bearing. The bush is integral and moves relative to the shaft, while some bearing bushes are segmented and rotate relative to the shaft.
Journal: the part of the shaft supported by the bearing;
Bush: the part that matches the journal;
Sleeve: a sleeve made into a full cylindrical shape.
In the LEGO Mindstorms series and BioTrans RoSys series robot components, the sleeve specifically refers to the silver-gray LEGO standard shaft holder, which is divided into full sleeve and 1/2 sleeve.
Material of the sleeve
Specifications of plastic sleeves: POM polyoxymethylene plastic sleeves, PA nylon plastic sleeves, PTFE polytetrafluoroethylene plastic sleeves, Teflon plastic sleeves, Teflon plastic sleeves.
Characteristics of plastic sleeves: acid, alkali, corrosion, mechanical strength, good wear resistance, heat resistance, oil resistance and chemical resistance. The materials of plastic sleeves include PTFE/Teflon/Teflon/polytetrafluoroethylene, polyoxymethylene POM, nylon PA, and polypropylene PP. Products are used in aerospace, automobiles, sensors, medical, pharmaceuticals, satellites, valves, pumps, sanitary ware, electronics, bearings, electrical appliances, and other industries.
Bimetallic sleeve parts material is a patented product and a new material for profiled and standardized sleeve products. It mainly provides bimetallic sleeve parts near net shape materials (Near Net Shape Material) for various sleeve processing companies, general machinery factories, and machinery repair companies. With this bimetallic sleeve parts material, only a small amount of mechanical processing (such as chamfering, drilling, turning or oil troughing) is required to become a sleeve product for direct installation.
What is the role of copper sleeves in machinery?
1. Fixation
When the gear shaft is moving, try not to let it deviate in direction due to vibration. At this time, copper sleeves are needed to help fix it. The most important role of copper sleeves in machinery is to fix the position, which is all the performance of copper sleeves.
2. Sliding bearings
This is another role played by copper sleeves in machinery. In order to reduce expenses and save costs, sliding bearings are needed at this time, and copper sleeves just have this function. It mainly designs the thickness of the sleeve of the sliding bearing according to the axial direction of the bearing. In fact, the copper sleeve is a kind of sliding bearing. When the rotation of the machine is relatively low and the clearance requirement is relatively high, the copper sleeve can be used to replace the rolling bearing for operation. The copper sleeve is wear-resistant and can be used for a long time, so to a large extent, this can help save costs.
Where are copper sleeves mainly used?
The copper sleeve on the shaft acts as a bearing and belongs to the category of sliding bearings. It is a bearing that works under sliding friction and rotates relative to the shaft. Generally, it needs to be assisted by a lubrication system. Sliding bearings work smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can also greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption ability
The functions are lubrication, heat dissipation, friction reduction, and life extension.
Copper bushings are mainly used in machinery, printing and dyeing, papermaking, chemical industry, aerospace, coal, petroleum, automobile, engineering machinery, metallurgy and other industries.
