壓力表疲勞試驗臺的組成與測試

發布時間:2022-07-22 13:40:17   發布人:http://www.9015c.com
壓力表出廠前,需要對樣品進行耐久性試驗,即疲勞試驗。反復按壓和釋放壓力數萬次,以確定壓力是否合格。本公司所生產的壓力表疲勞試驗臺,通過電腦控制的增壓系統,可以進行反復的增壓、泄壓操作。下面來講講壓力表疲勞試驗臺的組成與測試內容吧。
Before the pressure gauge leaves the factory, it is necessary to carry out durability test on the sample, that is, fatigue test. Press and release the pressure repeatedly for tens of thousands of times to determine whether the pressure is qualified. The fatigue test bench of the pressure gauge produced by our company can repeatedly pressurize and relieve pressure through the computer-controlled pressurization system. Now let's talk about the composition and test content of the pressure gauge fatigue test bench.
壓力表疲勞試驗臺的組成:
Composition of pressure gauge fatigue test bench:
疲勞試驗臺主要由加壓水泵、加壓閥和泄壓閥組成,構成加壓泄壓系統。在控制系統、數據采集系統等輔助測控裝置的配合下,自動完成疲勞試驗的循環動作和試驗。對結果進行判斷和統計,形成檢測報告。試驗過程中可實現無人操作。
The fatigue test-bed is mainly composed of a pressurized water pump, a pressurized valve and a pressure relief valve, forming a pressurized pressure relief system. With the cooperation of control system, data acquisition system and other auxiliary measurement and control devices, the cycle action and test of fatigue test are automatically completed. Judge and count the results, and finally form a test report. Unmanned operation can be realized during the test.
試壓泵的轉速由變頻器根據設定的高壓水源壓力進行控制,使高壓水源壓力盡可能保持穩定。用節流閥調節充放電流量,達到試驗要求的升壓和泄壓所需時間。通過以上措施,在被測樣品失效前保證了每次升壓和降壓過程的一致性。當發生故障時,壓力會發生突變,測試系統可以監測被測樣品的異常壓力。判斷早期失敗(與設定的試驗次數相比)。
The rotating speed of the pressure test pump is controlled by the frequency converter according to the set high-pressure water source pressure, so as to keep the high-pressure water source pressure as stable as possible. Adjust the charge and discharge flow with throttle valve to meet the time required for pressure rise and pressure relief required by the test. Through the above measures, the consistency of each step-up and step-down process is ensured before the tested sample fails. When a fault occurs, the pressure will suddenly change, and the test system can monitor the abnormal pressure of the tested sample. Judge the early failure (compared with the set number of tests).

氣液增壓泵廠家提醒您,壓力表試驗臺由低壓動力泵、高壓增壓器、沖水泵以及電路控制系統組成。可以完成壓力表的疲勞試驗,與基準表相對比,測試壓力表穩定性與準確性,可以自行設定試驗壓力與試驗次數、試驗頻率,達到試驗次數,自動停機并報警的功能。
The manufacturer of gas-liquid booster pump reminds you that the pressure gauge test bench is composed of low-pressure power pump, high-pressure booster, flushing pump and circuit control system. It can complete the fatigue test of the pressure gauge, compare with the benchmark gauge, test the stability and accuracy of the pressure gauge, and set the test pressure, test times and test frequency by itself, so as to achieve the function of test times, automatic shutdown and alarm.
