耐壓試驗臺它的壓力試驗系統如何,在做氣密性測試時候需要注意什么事項?下面試驗臺廠家的小編給大家詳細介紹。
Explosion pressure test stand, its pressure test system, in doing airtight test what matters need to pay attention to the following explosion test rig manufacturers Xiaobian to introduce in detail.
一、耐壓試驗臺壓力試驗系統
Blasting pressure test stand pressure test system
由加壓系統和控制、顯示系統組成。加壓系統主要由思明特液體增壓泵等組成,主要完成系統的加壓和保壓工作,可確保長時間試驗的加壓及保壓。其試驗壓力、升壓速率等參數可以在試驗程序中進行設定。設定后機器可以自動完成,該設備使用介質可以為水,可以對軟管進行壓力、膨脹、變形性能檢測,各項功能既可以單獨進行測試也可以進行綜合試驗,提高了設備的使用率,且設備具有性能穩定,操作簡單,維修方便的特點。
It consists of a compression system and a control and display system. The system is mainly composed of super pressure liquid booster pump and other components, mainly completes the system pressure and pressure, pressure and pressure to ensure long time test. The parameters such as test pressure and step up rate can be set in the test program. After setting the machine can automatically complete, the equipment used for medium water, can the pressure hose, expansion deformation, performance testing, all functions can be tested independently can also be carried out comprehensive test, improve the efficiency of the equipment, and the equipment has the advantages of stable performance, simple operation, convenient maintenance.


二、氣體增壓系統等氣密性檢測裝置在氣密性測試時的注意事項
Two, gas pressurization system and other air tightness testing device in the test of air tightness matters needing attention
1.為保護非升壓監視用壓力表,在升壓之前,應關閉氣密性試驗臺儀表導壓管。
1. for the protection of non pressure monitoring pressure gauge, before the boost, the gas tightness test stand, instrument pressure pipe should be closed.
2.為隔開系統而插入盲板的法蘭應在試運轉階段用工作介質進行試漏。
2. flanges inserted into blind plates for the separation of the system shall be tested with a working medium during the commissioning phase.
3.升壓時應緩慢進行,氣密壓力不得超過規定限值。
3., the pressure should be slow, airtight pressure shall not exceed the specified limit.
4.泄壓時應盡可能由低點或死角處的倒淋進行排放避免積液。
4., when the pressure should be as low as possible or low angle of the inverted pour discharge, to avoid effusion.
5.常壓系統不做氣密試驗。
5. atmospheric pressure system does not do airtight test.
6.氣密試驗需要按設備、管線的壓力等級劃分為適當的系統。
6. the tightness test shall be divided into proper system according to the pressure grade of equipment and pipeline.
7.系統與系統之間的管線用閥門隔開,必要時用盲板隔開,泵體均用盲板隔開。
7. the pipeline between the system and the system is separated by valves, and separated by blind plates when necessary. The pump bodies are separated by blind plates.
8.物料進出裝置的管線也必須進行氣密試驗。
8. the pipeline of the material inlet and outlet device must also be airtight tested.
9.公用工程系統管線盡可能用管線內的介質進行氣密試驗。
9. the utility system can conduct airtight test as much as possible by using medium in the pipeline.
