People believe that a lot of books to know welding material, then how many people know that mechanical energy and chemical composition of the welding material?A. for low carbon steel, medium carbon steel and low alloy steel, can be used with the base strength grade corresponding electrode, the tensi

Aluminum alloy die casting products is mainly used in electronics, automobile, motor and some of the communications industry, etc., of course the main purpose or on some equipment parts, then we need to be paid attention in aluminum alloy die casting club?A, consider the problem of demoulding,Second

Whether to use what equipment, engaged in what industry, users care about most is always the production efficiency, without a doubt, is also the goal of equipment manufacturer is trying to achieve.In this paper, the red star experts explain for everybody permanent magnet drum magnetic separator.The

Pneumatic high-pressure ball valve is mainly used to truncate or on line in the medium, can also be used for regulation and control of the fluid, and ball valve in the pipeline is not only more connected the confluence of flexible control medium, and the flow switch, at the same time also can close

Cast iron welding rod because of high carbon content, the organization is not uniform, low strength, poor plasticity, belong to the poor weldability of material, process easy to produce crack;Cold after welding speed fast, is easy to produce white tissue caused by machining difficulty.Cast iron weld

Forging materials are mainly components of carbon steel and alloy steel, followed by aluminum, magnesium, copper, titanium and its alloys.Material of the original state has a bar, ingot casting, metal powder and liquid metal.Metal in the deformation of the cross-sectional area before and after defor

Technical requirements including the mechanics performance of the aluminum alloy die casting, die casting dimension and surface quality.1, mechanical property, when adopt the die casting sample inspection, mechanical properties should comply with the regulations of GB/T15115.When die casting body te

Note the amount of fat forged steel valves often ignore.Note grease gun after lubrication, low temperature cut-off valve selection operators valves and greasing connection, on the operations.There are two forged steel gate valve: on the one hand, on the quantity is little greasing, sealing surface d

Magnetic separation is choose by the difference of magnetic mineral grain for points.When mineral grains and gangue particles by magnetic separator, magnetic field due to the magnetic mineral grains are different, under the action of magnetic field, their way to different sports.Magnetic particles b

Equipment installation after the leaking problem recently, is still a pure water machine after installing leakage due to improper installation technique, water leakage at the point of failure (pressure barrels of copper ball valve).The following paper analyzes the reasons of leaking:The first, secon
