液壓萬能試驗機在建筑裝飾材料、金屬復合材料的結構力學檢測處起著關鍵的功效。其可以精確的所必須的測試數據，因此液壓機拉伸試驗機在大中型鋼鐵行業(yè)及其質量檢驗企業(yè)試驗室中獲得了普遍應用。可是在液壓機拉伸試驗機的應用全過程中，人們理應留意對其的維護保養(yǎng)和維護保養(yǎng)。許多實驗工作人員針對液壓機拉伸試驗機應用中出現(xiàn)的常見故障，常常埋怨。我覺得許多難題都由于實驗工作人員針對液壓機拉伸試驗機應用全過程中不留意其恰當的方法，可能會導致試驗儀出現(xiàn)難題。假如對液壓機拉伸試驗機有充足的了解，則人們就能夠非常好地防止事兒的產生。那麼，怎樣保證液壓機拉伸試驗機的恰當維護保養(yǎng)及其該機器設備的校零常見問題你掌握嗎

Hydraulic universal testing machine plays a key role in structural mechanics testing of building decorative materials and metal composite materials. It can accurately test the necessary data, so the hydraulic press tension testing machine has been widely used in large and medium-sized steel industry and its quality inspection enterprise laboratories. However, in the whole process of application of Hydraulic Press Tension Testing machine, people should pay attention to its maintenance and maintenance. Many experimenters often complain about the common faults in the application of Hydraulic Press Tension Testing machine. I think many difficulties are due to the fact that the experimenters do not pay attention to the proper methods during the whole process of the application of the hydraulic press tension testing machine, which may lead to the difficulties of the tester. If we know enough about the hydraulic press tension testing machine, people can prevent things from happening very well. Then, how to ensure the proper maintenance of the hydraulic press tension testing machine and the common problems of zero-calibration of the machine and equipment?

一、如何做到液壓萬能試驗機的正確維護

How to Maintain the Hydraulic Universal Testing Machine Correctly

用合適的夾具完成相應的實驗。液壓萬能試驗機只配有標準試樣的夾具，而對于非標準的式樣就需要用合適的夾具來配合其使用，以保證試驗的精確性。

Complete the corresponding experiment with the appropriate fixture. Hydraulic universal testing machine is only equipped with fixtures for standard samples, and for non-standard patterns, it is necessary to use appropriate fixtures to cooperate with its use in order to ensure the accuracy of the test.

液壓萬能試驗機的清掃與清潔工作。試驗過程中不可避免的會出現(xiàn)一些粉塵。這些粉塵如果得到不到及時的清理，就有可能給液壓望能試驗機帶來重大的損害，所以每次使用后就必須進行清掃工作。

Cleaning and cleaning of hydraulic universal testing machine. Some dust will inevitably appear during the test. If these dust can not be cleaned up in time, it may cause great damage to the hydraulic energy expectancy testing machine, so it must be cleaned after each use.

及時補充液壓油。液壓油是要在一定時期進行補充的。

Replenish hydraulic oil in time. Hydraulic oil should be supplemented in a certain period of time.

過濾器的更換。一般來說對于帶堵塞指示器的過濾器要及時檢測更換，而不帶堵塞指示器的液壓萬能試驗機應當每六個月?lián)Q一次。

Replacement of filters. Generally speaking, the filter with blocking indicator should be detected and replaced in time, and the hydraulic universal testing machine without blocking indicator should be replaced every six months.

定期檢查元器件。

Check components regularly.

緊固件要定期進行鎖緊。試驗的過程可能帶來緊固件的松動，因而要定期對其進行處理。

Fasteners should be locked regularly. The process of test may bring about loosening of fasteners, so it should be treated regularly.

冷卻器的清理和檢查。定期觀察冷卻器情況，如果有積垢，要及時清理。

Cleaning and inspection of cooler. Regular observation of the cooler, if there is fouling, to clean up in time.

蓄能器的補充問題。如果蓄能器中的壓力不夠，就及時的補充。

Supplementary problems of accumulator. If the pressure in accumulator is not enough, it should be supplemented in time.

傳動部分及時進行涂抹潤滑劑。這樣能夠減少摩擦。

The transmission part is coated with lubricant in time. This reduces friction.

二、液壓萬能試驗機調零的注意事項

II. Notices for Zero Adjustment of Hydraulic Universal Testing Machine

零點過大時，先調節(jié)零點，然后在各檔位分別對軟件清零

When the zero is too large, first adjust the zero, then clear the software in each gear.

油缸未升起時，試驗力顯示負值，屬于正?，F(xiàn)象，請不要調整零點

When the cylinder is not raised, the test force shows a negative value, which is a normal phenomenon. Please do not adjust the zero point.

對于零點的調整，應在引伸計在試樣上裝夾完畢后，且試驗活塞處于靜止狀態(tài)時進行

For the adjustment of zero point, it should be done after the extensometer is clamped on the sample and the test piston is in a static state.

液壓萬能試驗機一般情況下，調速人員已將傳感器的零點調整好，每次啟動時，系統(tǒng)會自動校準啟動零點，無需用戶再調整

Generally speaking, the governor has adjusted the zero of the sensor well. When the system starts up, the zero of the sensor will be automatically calibrated without any readjustment by the user.

用戶可以用硬件調零按鈕調整硬件零點，系統(tǒng)會自動記錄新的零點調整值

Users can adjust the hardware zeros with the hardware zeros button, and the system will automatically record the new zeros.

不分檔測量沒有調節(jié)零點，因此對于液壓萬能試驗機來說，因為是全程不分檔，因此該事項適用于電子萬能試驗機。

Non-grading measurement does not adjust zero point, so for hydraulic universal testing machine, because the whole process is non-grading, so this matter applies to electronic universal testing machine. http://www.gdxinli.com.cn/
