As the scale of the essential part-scale set,the selection of material and performance will directly affect the life of the platform balances,what kind of this scale suitable to use?This problem has become one of the key factors to meet the choose and buy.Each manufacturer produces various scales of Taiwan very much the same,the following analysis and the scale body structure classification and performance:
According to meet scale body structure can be divided into:U shaped steel platform balances,channel steel platform balances,meet range,reinforced concrete platform balances(local cement scale)
1,channels and U shaped steel contrast.Why choose U meet steel and don't choice meet channel?You can see the details as below:
(1)first mentioned is scale body, it is for the channel steel girder,again with horizontal clapboard a series of linked together,with the bottom again boards.
U shaped steel scale body,it is according to the principle of bridge,with U shaped steel at the bottom for support,no boards,and no mode of partition.
In comparison,of the same size scale body, channel steel scale weight in U shaped steel scale body.Cost to U shaped steel than scale body high.Channel steel scale body boards have a tension,U shaped steel is not.
(2)And from the point of view of welding it,U steel welding is full scale,and channel steel scale is spot welding.So,the industry think,U shaped steel than channel steel better.
The current market of the main production platform balances manufacturer with U shaped steel and channel steel,which U meet of profiled steel structure in the market become mainstream,in the United States,Germany,China and the world meet manufacturer adopt U steel structure,U shaped steel platform balances.
(3)The third generation weighing apparatus products belong to channel steel,channel steel says at the bottom of the two way hold heavy beam,and the middle is empty,so hold heavy performance will send some.Simple said steel structure ratio is not very reasonable,channel steel scale and then USES the steel plate piece together up.But from the scale is also weighed the tonnage channel steel than U shaped steel heavy,the truth.
U shaped steel is industrial instruments,the fourth generation products,U shaped steel scales equipped with equipment must be is bending machine.The 600 T large dual machine type bending machine,cutting machine higher precision and speed,the equipment for the most advanced in the industry.The bending machine on the market to buy it to more than 60,so U shaped steel scale price is more expensive to channel.Steel structure is more reasonable,good stiffness,strength,resist lateral force strong,so the scale body resistance,long life.U shaped steel bottom is the structural design of the bridge.
U shaped steel scale bench with U girders 5-7 root (according to the tonnage and mesa dimension design),so as to ensure a balance overall rigidity,scale in full seal machine cavity,is not easy to rust,steel plate after peen-forming derusting treatment,using epoxy zinc-rich primer and bingxisuan Marine paint,oil film thick, thickness are 100 microns,compression,acid,alkali,corrosion resistance stronger.
2,the range of steel also say,is the strip steel for i-section section.The specifications to waist height (h) legs wide (b) * waist thick (d) number of hair,said such as "work 160 * 88 * 6," meaning that waist height is 160 mm,and the legs for 88 mm wide,waist thick for 6 mm range of.The specifications of the range can also be used said model,model said the high number of cm waist,such as work 16 #. Waist high the same range,such as there are several different legs wide or waist thick,need to be in the right model with a b c be difference, such as 32 a # 32 b # 32 c #, etc.Ordinary light and range points range range,the specifications of the hot rolling average range for 10-63 #.The agreement between the supply and demand of the supply of hot rolling average range for 12-# 55 specifications.Widely used in all kinds of range building structures,bridge,vehicles,support,machinery, etc.
Because in car weighing apparatus industry range is less use,at home and abroad together with U shaped steel and the main channel steel,in here,I will no longer be a detailed analysis.
3,reinforced concrete platform balances (local cement scale) with full electronic platform balances,digital platform balances,analog platform balances,the biggest difference lies in the scale of body structure is different,the former is reinforced concrete structure,and the latter is the steel structure.These platform balances (truck scale of local platform balances) used in instrument,connection box,printer in accord with sensors,working principle,lightning protection facilities basic same, meet the construction of the foundation,on the function no essential difference between.But the cement scale in the production cycle than the steel structure of the much longer,so as to use cement scale meet,it's best to agree,the early early manufacturers,to avoid delay platform balances of input use of time.
Cement scale advantages:fundamentally solve the whole steel structure platform balances use process for rain insolation,acid and alkali corrosion and structure of the heat bilges cold shrink and appear scale body corrosion,high precision,long service life and shorten the lower problems such as corrosion resistance ability,structure stability,since the major,positioning allowed,deformation,free maintenance.
Applicable for public stand,chemical enterprise,pound ports,refrigeration industry etc to preservation function demand higher industry.
Cement scale construction features:the box USES professional profile form,internal is double steel cloth,is used to connect the bolt type service life of 20 years, specific parameters and construction process please read "cement scale" |
