故障及解決方法：

一、拉力試驗機加荷時(shí)，指針顫動(dòng)或時(shí)走時(shí)停

1、離合器齒輪磨損：需要修理或更換。

2、摩擦盤(pán)的皮墊圈或彈簧磨損：需更換皮墊圈或彈簧。

3、操縱手柄移位：調整操縱手柄，使其與牙槽配合好。

二、更換擺砣時(shí)指針不回零

1、拉力試驗機安裝不水平：用水平儀把試驗機調整水平。

2、擺錘不垂直：只掛A砣。調整平衡砣，使之垂直。

三、拉力試驗機擺錘回位太快或太慢

1、緩沖閥擋位位置放置不當：調整緩沖閥到適當位置。

2、液壓油黏度過(guò)低或過(guò)高：液壓油黏度過(guò)低時(shí)擺錘回落快，黏度高時(shí)回落慢．應更換適當黏度的液壓油。

3、緩沖閥內、油管內或液壓油有臟污：清洗緩沖閥、油管。更換液壓油。

四、拉力試驗機指針回零滯怠或不穩定

1、指針軸承、主軸軸承銹蝕或有油污：清洗或更換軸承。

2、齒桿變形或齒桿與齒輪不嚙合：校直齒桿或清洗、修整齒輪、槽輪等傳動(dòng)部件。

3、緩沖閥內有臟污：清洗緩沖閥。

五、拉力試驗機示值正偏差

1、短臂刀刃有松動(dòng)：把刀刃緊牢。

2、擺砣偏輕：給砣配重（要兼顧A、B、C砣的重量）。

六、示值負偏差zui主要原因是各部件之間的摩擦阻力過(guò)大

1、指針軸承、擺軸軸承和測力傳動(dòng)部件摩擦阻力過(guò)大：主要是調整、清洗軸承及測力傳動(dòng)部件．消除不正常的摩擦阻力。

2、上夾頭、從動(dòng)針彈簧片松緊度和描繪裝置的摩擦阻力大：調整上夾頭、從動(dòng)針彈簧片松緊度和描繪裝置部件．消除不正常的摩擦阻力。

3、活塞桿與擺桿相接部位不靈活：調整兩者相接部位。使之靈活自如。

七、從動(dòng)針滯阻或移位

1、從動(dòng)針彈簧片彈力大小或從動(dòng)針與指示盤(pán)摩擦阻力大小造成的影響：調整從動(dòng)針彈簧片的彈力或從動(dòng)針與指示盤(pán)的問(wèn)隙。

2、從動(dòng)針兩端重鼉有偏差：調整兩端重量，使其平衡。

八、示值無(wú)規律的偏差

1、齒桿、齒輪有油污、磨損或有毛刺：消除齒桿、齒輪的油污、毛刺，找出超差時(shí)的齒桿接觸點(diǎn)，然后修正齒桿、齒輪；如不能消除誤差．更換齒桿、齒輪。

2、拉力試驗機試驗機安裝不水平：調整水平。

3、齒桿彎曲：校直或更換齒桿，調整滾動(dòng)槽輪的問(wèn)隙。

九、計算機軟件聯(lián)機后出現提示框信息顯示超載。

解決方案是檢查計算機與試驗機的通訊線(xiàn)是否脫落;檢查聯(lián)機選擇傳感器是否選擇正確;檢查zui近的試驗或操作鍵

盤(pán)時(shí)傳感器是否被撞過(guò);檢查出現問(wèn)題之前是否使用了軟件的校準或標定功能;檢查是否手動(dòng)更改過(guò)校準值、標定值或硬件參數中的其他信息。

十、試驗機主機電源不亮，不能上下移動(dòng)。

解決方案是檢查接入試驗機的電源線(xiàn)路是否連接正常;檢查急停開(kāi)關(guān)是否處于擰起狀態(tài);檢查接入試驗機的電源電壓是否正常;檢查機器插座上的保險是否燒斷，請取出備用保險絲安裝即可。

十一、試驗機主機電源有電但設備不可以上下移動(dòng)。

解決方案是檢查是否是15S（時(shí)間）以后設備還無(wú)法移動(dòng)，因為主機開(kāi)機需要自檢，大概需要15S時(shí)間;檢查上下限位是否再恰當的位置，有一定的運行空間;檢查接入試驗機的電源電壓是否正常

。fault and solution method:

A, tensile test machine, vibration or pause the pointer

1, the clutch gear wear: the need for repair or replacement.

2, the skin friction disc washer or spring wear: need to change the skin or spring washer.

3, handle shift: to adjust the control handle, make it fit in with the alveolar.

Two, the replacement of pendulum weight when the pointer does not return to zero

1, tensile testing machine installation is not level: the level to adjust the level of test machine.

2, not only the vertical pendulum hanging weight: A. Adjust the balance weight, so that the vertical.

Three, tensile testing machine, the pendulum back a bit too fast or too slow

1, the buffer valve gear position placed improper: adjust the buffer valve to the appropriate location.

2, the hydraulic oil viscosity is too low or too high: hammer down fast swing hydraulic oil viscosity is too low, viscosity is high down slowly. Should be proper replacement of 

hydraulic oil viscosity.

Vittae 3, buffer valve, or hydraulic oil dirty: washing buffer valve, pipe. Replacement of hydraulic oil.

Four, tensile testing machine pointer back to zero lag or unstable

1, the pointer bearing, spindle bearing corrosion or oil: clean or replace bearing.

2, toothed bar deformation or toothed bar and gear is not engaged: straightening toothed bar or washing, dressing gear, wheel, transmission parts.

3, the buffer valve with cleaning: cleaning buffer valve.

Five, tensile testing machine showing the value of positive deviation

1, the short arm loose: the knife blade tightly.

2, swing weight lighter: give weight weight （both A, B, C weight weight）.

Six, showing the value of negative deviation is the main reason of the frictional resistance between the units is too large

1, the pointer shaft bearing, bearing and power transmission parts friction resistance is too large: mainly adjustment, cleaning bearings and force transmission parts to 

eliminate the friction resistance is not normal.

Friction resistance on 2, chuck, driven needle leaf spring tightness and describe the adjustment device: chuck, driven needle leaf spring tightness and drawing device 

components. To eliminate the friction resistance is not normal.

3, the piston rod and the swing rod is connected with the flexible adjustment of both parts not connected parts. The flexible.

Seven, the driven needle stagnation or shift

Effect of 1, driven needle leaf spring elastic force or driven needle and dial friction resistance caused by the gap adjustment driven needle: the elasticity of the spring piece 

or driven needle and dial.

2, the driven needle are heavy alligator deviation: adjusting the weights, the balance.

Eight, showing the value of deviation is irregular

1, rack, gear oil, abrasion or burr: eliminate the rack, gear oil, burr, find out the pole difference when the contact points, and then modified tooth bar, gear; if not eliminate 

errors. Replace the tooth bar, gear.

2, tensile testing machine testing machine installation is not level: level adjustment.

3, toothed bar bending: alignment or replacement tooth bar, adjust the roll gap groove wheel.

Nine, computer software on-line prompt box display information overload.

The solution is to check the computer and test machine communication line is off; check the online selection of sensor is correct; check the last test or operation keys

When the sensor is knocked off; check whether the use of a software appears calibration or calibration before; check whether the manual modified calibration values, 

calibration information value or other hardware parameters in the.

Host ten, the power of the testing machine does not light, not to move up and down.

The solution is power line inspection access testing machine is connected properly; check the emergency stop switch is in screwed up state; power supply voltage check 

access testing machine is normal; check the socket on the insurance is burned off, remove the spare fuse can be installed.

Host eleven, testing machine power supply with power but the equipment can not move up and down.

The solution is to check whether it is 15S （time） after the device is unable to move, because the host boot take self-inspection, probably need 15S time; check the upper 

and lower limit is again appropriate position, operating space; check supply voltage access testing machine is normal.
