How to solve the oil leak in the feed pump?
Porous metal material: porous metal is a kind of powder material. It has porous tissue. If it is immersed in lubricating oil, it fills with lubricating oil and becomes oil bearing, it has self-lubricating property. The toughness of porous metal material is small, it is only suitable for smooth impact free load and medium and small speed.
Among them:Bearing alloy bearing alloy and alloy alloy is mainly white, tin, lead, antimony or other metal, because of its good wear resistant, high plasticity, good running performance, good thermal conductivity and anti adhesive and good adsorption and oil well, it is suitable for heavy load and high speed condition the bearing strength of gold is relatively small, the price is more expensive, the use must be cast in bronze, steel or cast iron bearing on the formation of thin coating.
Bearing materials are:1) metallic materials, such as bearings, alloys, bronze, aluminium based alloys, zinc based alloys, etc.;2) porous metallic materials (powder metallurgy materials);3) non-metallic materials.
Bearing materialThe bush or bearing is an important part of the sliding bearing, and the material of the Bush and bearing lining is collectively called bearing material. As the bush or liner is in direct contact with the shaft neck, the general journal parts are more wear resistant, so the main failure form of the Bush is wear. The wear of the Bush is directly related to the material of the journal, the Bush itself, the lubricant and the lubrication state. The selection of the bush material should take all these factors into consideration so as to improve the service life and work performance of the sliding bearing.
