關(guān)于如何調(diào)整液壓萬能試驗(yàn)機(jī)的級別,濟(jì)南試驗(yàn)機(jī)廠家為您解說:
How to adjust the hydraulic universal testing machine level, Ji SPAN machine< test nan>manufacturers to explain for you:
試驗(yàn)機(jī)一般都有很多的垂直承載立柱,立柱上有安裝一個(gè)固定的水平基座,在頂部還有一個(gè)可以移動的十字橫梁?,F(xiàn)代新型的液壓萬能試驗(yàn)機(jī),立柱上一般裝有滾珠絲杠用以固定可移動的十字頭。液壓萬能試驗(yàn)機(jī)的大小用框架的承載水平和測量載荷/拉力的測力計(jì)來共同表征。測力計(jì)安裝在依靠電動馬達(dá)或液壓裝置驅(qū)動的可移動的十字頭上。帶夾具的系列測力計(jì)測量力的大小,可以通過數(shù)字顯示器或PC機(jī)顯示結(jié)果。很多萬能試驗(yàn)機(jī)具有可互換的測力計(jì),因此可以與所測試的不同材料匹配。靜態(tài)試驗(yàn)利用標(biāo)準(zhǔn)的液壓萬能試驗(yàn)機(jī)來進(jìn)行,通常加載速度范圍為0.001~20 in./min(1in.=2.54cm)。動態(tài)試驗(yàn)或循環(huán)試驗(yàn)如裂紋增長和疲勞試驗(yàn)通常利用液壓伺服系統(tǒng)萬能試驗(yàn)機(jī)來進(jìn)行,時(shí)間較長,載荷較低。
Testing machine generally have many vertical bearing column, column are arranged on ahorizontal base fixed, at the top and a movable cross beam. Modern hydraulic universal testing machine, the column are usually equipped with ball screws to fix the movablecrosshead. Hydraulic universal testing machine with the size of the framework of themaximum load level and load / force measuring dynamometer to common characterization.The dynamometer is installed on the cross head on electric motors or hydraulic device to drive the movable. Series of dynamometer measurements with clamping force size, the results can be displayed by digital display or a PC machine. A lot of universal testing machine with interchangeable dynamometer, so it can be matched with different materials testing. The static test with standard hydraulic universal testing machine to carry out, usually the loading speed is in the range of 0.001~20 in./min (1in.=2.54cm). Dynamic test and cycle test such ascrack growth and fatigue test often used the hydraulic servo universal testing machine system for a long time, low load.
液壓萬能試驗(yàn)機(jī)通過不同速度級別的調(diào)節(jié),對塑料材料樣條進(jìn)行拉伸、彎曲、壓縮或牽引,這是塑料混配實(shí)驗(yàn)室中普通的設(shè)備。在混配料的制備過程中,利用測試材料能夠判斷材料是否適用于某些特定的加工應(yīng)用或終端應(yīng)用。還可以用于產(chǎn)品的質(zhì)量控制,以確保產(chǎn)品質(zhì)量各個(gè)批次之間的一致性。
Hydraulic universal testing machine by different speed level adjustment, the plastic materialspline tensile, bending, compression or traction, this is the most common plastic mixed withlaboratory equipment. In the process of preparing mixed ingredients, using the test materialsto determine whether the material is applied in some special processing applications orterminal application. Can also be used to control the quality of the products, to ensure the consistency between each batch of product quality.
目前,利用液壓萬能試驗(yàn)機(jī)所測試的常見的項(xiàng)目是拉伸強(qiáng)度和拉伸模量、彎曲強(qiáng)度和模量。一般來說,立式設(shè)備的體積更小也更易于操作,并且還能借助于樣品自身的重力,使棘手的樣品如薄膜也能同較重的注塑部件一樣易于操控。單立柱萬能試驗(yàn)機(jī)的力程較低,價(jià)格也較低,結(jié)構(gòu)容量一般為1000 lb.門式的萬能試驗(yàn)機(jī)的結(jié)構(gòu)容量可達(dá)1000~135000 lb.測力計(jì)也以某一的適用于萬能試驗(yàn)機(jī)結(jié)構(gòu)和樣品的力值為分類依據(jù)。例如,一個(gè)100 lb的測力計(jì)安裝在1000 lb的??蚶铮梢蕴峁?00 lb的試驗(yàn)載荷。測力計(jì)的容量不應(yīng)超過樣品預(yù)測斷裂載荷太多,否則會影響試驗(yàn)結(jié)果的精確性。
At present, the hydraulic universal testing machine test the most common project is tensile strength and tensile modulus, bending strength and modulus. Generally speaking, smallervertical equipment is more easy to operate, and also with the help of sample self gravity, thedifficult samples such as film can also like injection molding components heavier easy manipulation. Range of single column universal testing machine is low, the price is low, the structure capacity generally structural capacity is 1000~135000 lb. ergometer 1000 lb. door type universal testing machine to apply a maximum in the universal testing machine structureand sample force value as the basis for classifying. For example, a dynamometer installed100 LB at 1000 LB die box, can provide a test load of 100 lb. The dynamometer capacityshall not exceed the sample predicted fracture load too much, otherwise it will affect theaccuracy of test results.
