電子萬能試驗(yàn)機(jī):壓力試驗(yàn)機(jī)的拉伸實(shí)驗(yàn):拉伸實(shí)驗(yàn)(地應(yīng)力-應(yīng)變力實(shí)驗(yàn))通常是將原材料試件兩邊各自夾在2個(gè)間距必須間距的工裝夾具上,兩工裝夾具以必須的速率分離出來并拉申試件,測定試樣上的應(yīng)力變化,直到試樣破壞為止。拉力機(jī)拉伸實(shí)驗(yàn)是科學(xué)研究材料力學(xué)抗壓強(qiáng)度最普遍應(yīng)用的方式 其一,必須應(yīng)用恒速健身運(yùn)動的。下邊來為大家一下下壓力試驗(yàn)機(jī)的安裝步驟及檢修常見問題,我們一起來瞧瞧吧。
Tensile test of pressure testing machine: Tensile test (in-situ stress-strain force test) usually clamps the two sides of the raw material specimen on the fixture with two necessary spacing. The fixture separates the two fixtures at the necessary rate and stretches the specimen to determine the stress change on the specimen until the specimen is destroyed. Tensile experiment of tension machine is one of the most widely used ways to study the mechanical compressive strength of materials. Constant speed fitness exercise must be applied. Next, let's take a look at the installation steps and common problems of the downward pressure testing machine.
壓力試驗(yàn)機(jī)的安裝步驟及檢修常見問題一、壓力試驗(yàn)機(jī)的安裝步驟壓力試驗(yàn)機(jī)應(yīng)安裝在清理、干躁、無振動且溫度適合的屋子里。壓力試驗(yàn)機(jī)的服務(wù)器、油源箱的放置部位應(yīng)依據(jù)試驗(yàn)儀外觀圖及路基圖明確?;A(chǔ)的上平面應(yīng)平整,用水平尺找平。待基礎(chǔ)干燥后,再安裝試驗(yàn)機(jī)。
Installation steps and common problems in overhaul of pressure testing machine 1. Installation steps of pressure testing machine Pressure testing machine should be installed in clean, dry, non-vibration room with suitable temperature. The locations of the servers and fuel tanks of the pressure testing machine should be defined according to the appearance and roadbed drawings of the tester. The upper plane of the foundation should be flat and leveled with a horizontal ruler. After the foundation is dried, the test machine is installed.
將試驗(yàn)機(jī)及油源分別搬運(yùn)到混凝土的基礎(chǔ)上,根據(jù)外型圖及地基圖,和油管尺寸確定主機(jī)和油源之間的距離和方向。
The distance and direction between the main engine and the oil source are determined according to the outline map, the base map and the size of the tubing.
然后用薄板墊入主機(jī)底部和基礎(chǔ)之間。再用0.05/1000的方形水平儀進(jìn)行找正,將方形水平儀放在油缸外表面上,在相互垂直的兩個(gè)側(cè)面找正其垂直度。其垂直度應(yīng)不大0.2/1000?;?qū)l式水平儀放在工作臺,找正其水平度,水平度應(yīng)不大于0.2/1000。
Then the thin plate is placed between the base and the base of the main engine. Then the square level instrument of 0.05/1000 is used to align. The square level instrument is placed on the outer surface of the cylinder and its perpendicularity is found on the two sides which are perpendicular to each other. Its perpendicularity should be less than 0.2/1000. Or put the bar level instrument on the workbench to find its level, which should be no more than 0.2/1000.
壓力試驗(yàn)機(jī)找正后,用混凝土將底腳螺帽澆筑,將電動機(jī)軸下邊的墊塊墊牢。合用混凝土將電動機(jī)軸下邊的間隙所有添充,維持電動機(jī)軸與混凝土基本的融合優(yōu)良,避免在應(yīng)用全過程因其受振動進(jìn)而試驗(yàn)儀不水準(zhǔn)。
After the pressure testing machine is aligned, the sole nuts are poured with concrete, and the pads under the motor shaft are firmly padded. The joint concrete fills up all the clearances under the motor shaft to maintain the basic fusion of the motor shaft and the concrete, avoiding the instrumentation of the tester due to its vibration during the whole application process.
地腳螺栓澆注后,在水泥未干燥前,不允許用地腳螺栓緊固試驗(yàn)機(jī)和開動主機(jī)(水泥干燥時(shí)間一般不少于10~15天),待水泥干燥后,用地腳螺栓將試驗(yàn)機(jī)固定在基礎(chǔ)上。對壓力試驗(yàn)機(jī)的安裝精度進(jìn)行復(fù)查,看是否與找正精度相符。如不符合,重新找正。
After grouting, it is not allowed to fasten the tester and start the main machine (the drying time of cement is not less than 10-15 days) before the cement is dried. After the cement is dried, the tester is fixed on the foundation with the foot bolt. Installation accuracy of the pressure testing machine is checked to see if it is consistent with the alignment accuracy. If not, correct again.
壓力試驗(yàn)機(jī)的安裝流程及維修注意事項(xiàng)二、壓力試驗(yàn)機(jī)的維修注意事項(xiàng)1、從壓力試驗(yàn)機(jī)上取出模塊時(shí),應(yīng)注意記錄其相對應(yīng)的位置,連接的電纜號,對于固定安裝的線路板,還應(yīng)按前后取下相應(yīng)的壓接部件及螺釘作記錄。
Installation process and maintenance precautions of pressure testing machine 2. Maintenance precautions of pressure testing machine 1. When removing modules from pressure testing machine, attention should be paid to recording their corresponding positions, connecting cable numbers, and for fixed circuit boards, the corresponding pressing parts and bolts should also be taken down before and after recording.
2、檢修時(shí)電鉻鐵應(yīng)放到隨手的正前方,杜絕檢修PCB線路板。烙鐵頭需作適度的整修,以融入集成電路芯片的電焊焊接,并防止電焊焊接時(shí)磕傷其他電子器件。
2. Electric ferrochrome should be placed in front of the hand during overhaul to prevent overhaul of PCB circuit boards. The soldering head needs to be properly repaired to incorporate into the welding of integrated circuit chips and to prevent other electronic devices from being damaged during welding.
3、線路板測量時(shí)應(yīng)找到相應(yīng)的焊點(diǎn)作為測試點(diǎn),不要鏟除焊膜,有的板子全部刷有絕緣層,則只有在焊點(diǎn)處用刀片刮開絕緣層。
3. When measuring PCB, the corresponding solder joints should be found as test points. Do not eradicate the solder film. Some boards are all brushed with insulating layer, and the insulating layer can only be scraped with blades at the solder joints.
4、測量線路間的阻值時(shí),應(yīng)斷電源,測阻值時(shí)應(yīng)紅黑表筆互換測量兩次,以阻值大的為參考值。
4. When measuring the resistance between lines, the power supply should be disconnected. When measuring the resistance, the red and black pens should be interchanged to measure twice, with the larger resistance as the reference value.
5、不應(yīng)隨意切斷相關(guān)線路。壓力試驗(yàn)機(jī)上的線路板大多是雙面金屬孔板或多層孔化板,印刷線路細(xì)而密,一旦切斷不易焊接,且切線時(shí)易切斷相鄰的線。
5. Relevant lines should not be cut off at will. The PCBs on the pressure testing machine are mostly double-sided metal orifice plates or multi-layer orifice boards. The printed circuit is thin and dense. Once cut off, it is not easy to weld, and it is easy to cut off adjacent lines when tangent lines are cut off.
6、查清線路板的電源配置及種類,根據(jù)檢查的需要,可分別供電或全部供電。應(yīng)注意高壓,有的線路板直接接入高壓,或板內(nèi)有高壓發(fā)生器,需適當(dāng)絕緣,操作時(shí)應(yīng)特別注意。
6. Check the power supply configuration and types of PCB. According to the need of inspection, power supply can be provided separately or totally. Attention should be paid to high voltage, some circuit boards are directly connected to high voltage, or there are high voltage generators in the board, which should be properly insulated. Special attention should be paid to operation.
