膠管尺寸,膠管內徑要適當,若膠管采用管夾固定或膠管穿過鋼板等間隔物時,也要注意膠管的外徑尺寸。

工作壓力,按照有關國際標準規定的液壓膠管的安全系數,一般推薦的工作壓力通常為膠管比較低爆破壓力值的四分之一。

沖擊壓力和疲勞壽命,膠管的選擇是根據液壓系統設計的比較高壓力值來確定的。沖擊壓力不會嚴重影響膠管的疲勞壽命,對于沖擊壓力特別頻繁的液壓系統,建議選用特別耐脈動沖擊的膠管產品。

溫度范圍,用戶應該在膠管質量規范允許的溫度范圍內使用膠管,并且如果連續作業,建議經常降溫。

化學相容性,若使用特殊的液壓介質,用戶應確保所選用的膠管總成其膠管內、外層,接頭及O型密封圈與介質相容。

高壓油管接頭在使用的過程中有一些需要注意的地方:

我們在搬運高壓油管的時候一定要注意不能導致外表進行摩擦,以免發生破損,雖然膠管是用來用的,但是我們也不能讓高壓油管的外表出現泄露現象。

不能把高壓油管進行彎折,這樣會導致高壓油管內部破損,對以后的使用添加很多不必要的麻煩。

高壓油管不要一上來就使用,建議用水之類的先過濾一下,有的高壓油管是耐酸堿的,我們不能使用與當前液體發生沖突的液體進行測試。

在安裝高壓油管接頭的時候一定要把它擰緊,以防液體泄露。

The size and inner diameter of the hose shall be appropriate. If the hose is fixed with pipe clamp or the hose passes through steel plate and other spacers, pay attention to the outer diameter of the hose.

Working pressure: according to the safety factor of hydraulic hose specified in relevant international standards, the generally recommended working pressure is usually one fourth of the minimum burst pressure of hose.

Impact pressure and fatigue life, the selection of rubber hose is determined according to the maximum pressure value designed by the hydraulic system. The impact pressure will not seriously affect the fatigue life of the rubber hose. For the hydraulic system with particularly frequent impact pressure, it is recommended to select the rubber hose product with special pulsation impact resistance.

Temperature range: the user should use the hose within the temperature range allowed by the hose quality specification, and it is recommended to cool down frequently if continuous operation.

Chemical compatibility. If special hydraulic medium is used, the user shall ensure that the inner and outer layers of the selected hose assembly, joints and O-rings are compatible with the medium.

There are some points needing attention during the use of high-pressure oil pipe joint:

When handling the high-pressure oil pipe, we must pay attention not to cause friction on the surface to avoid damage. Although the rubber hose is used, we can't let the appearance of the high-pressure oil pipe leak.

The high-pressure oil pipe cannot be bent, which will lead to the internal damage of the high-pressure oil pipe and add a lot of unnecessary trouble to the future use.

The high-pressure oil pipe should not be used immediately. It is recommended to filter the water first. Some high-pressure oil pipes are acid-base resistant. We cannot use the liquid that conflicts with the current liquid for testing.

When installing the high-pressure oil pipe joint, it must be tightened to prevent liquid leakage.
