1.如何實現(xiàn)線形彈簧與氮氣彈簧的轉(zhuǎn)換？如何決定氮氣彈簧的數(shù)量？
在轉(zhuǎn)換的過程中，步是要知道現(xiàn)有的模具所需的壓力要求，如果知道完成操作的所需壓力，可直接采用相應(yīng)噸位的氮氣彈簧。如果不知道所需總的壓力，可通過計算模具中原有線形彈簧所提供的總壓力求出。同時，必須要清楚所需壓力是初始壓力(預(yù)壓)還是終壓力(滿沖程)，一旦知道了這些，可得到所需總的壓力需求。找出線形彈簧壓力的常用的辦法是查閱制造商的產(chǎn)品壓力圖表，通過圖表，可知道模具中線形彈簧的規(guī)格，顏色，預(yù)壓和沖程，也可使用測壓計來得出彈簧的壓力。
2.安裝氮氣彈簧
在大多數(shù)應(yīng)用中的氮氣彈簧可以很容易地安裝在同一芯的口袋用來為螺旋彈簧。口袋的深度應(yīng)該有一個低限度的50%的長度的氣彈簧，以較大值為準(zhǔn)。在某些應(yīng)用中可以利用氣彈簧的安裝選項，如粘貼法蘭架，在該基地的氣缸蓋，及線程體風(fēng)格。這些選項提供更大的靈活性使用氮氣彈簧在現(xiàn)有的模具。
當(dāng)大小的氣彈簧選定的不匹配，彈簧被取代的有簡單的可以采取的步驟，然后再安裝氣彈簧。間隔或袖子可用于在口袋，如果氣彈簧小于彈簧，或氣體彈簧可能法蘭安裝在適當(dāng)?shù)奈恢谩Ｈ绻�現(xiàn)有的口袋是過于膚淺的，它可能是芯更深，如果可能的話，或氣體彈簧可能會預(yù)裝，以滿足空間的需求。
后一個關(guān)切時，安裝氣彈簧是利用流體的模具。直接接觸某些模具潤滑劑，冷卻劑和清潔工人可以有害氣體彈簧和應(yīng)予以避免。盾構(gòu)氣體彈簧免受有害液體和提供足夠的排水系統(tǒng)，在氣彈簧的口袋。
3.如何為氮氣彈簧充氣?
在進(jìn)行充氣之前，要確保活塞桿充分伸展到頂端，如在沒有伸展的情況下進(jìn)行充氣，將導(dǎo)致定位環(huán)處于不正確的位置。用T型扳手?jǐn)Q入活塞頭頂端的螺孔，待用適當(dāng)?shù)墓ぞ唔攭撼錃忾y，使缸體內(nèi)的氣體排盡后，用力向上拉動活塞桿，使得活塞套與定位環(huán)頂緊為止。
4.氮氣彈簧充氣
(1)氮氣彈簧充氣需要使用專用的充氣臺或充氣裝置。對于獨立式如果動運輸方便可以先充好氣、座板系統(tǒng)氮氣彈簧側(cè)一定要在工作現(xiàn)場進(jìn)行充氣。
(2)氮氣彈簧充氣壓力在20℃時，標(biāo)準(zhǔn)壓力為150(bar)，如果小于130bar充氣，用普通氮氣瓶即可完成。高于130bar的充氣則需用增壓裝置來完成。
(3)充氣前請確認(rèn)安全擋圈是否安上，并用T型把手使柱塞桿完全伸出，之后調(diào)整好所需充氣壓力值，進(jìn)行充氣。
(4)充氣時，氣流流經(jīng)充氣閥的速度不要太快，以免充壞充氣閥引起漏氣，充氣完成后用螺塞封好充氣口。
注意：充氣過程中一定要安全操做，要經(jīng)過安全培訓(xùn)后方可進(jìn)行，以免發(fā)生不必要的傷害。

1 how to realize the linear spring and nitrogen conversion? How to decide the quantity of nitrogen spring?
During the translation process, the first step is to know the existing mold the desired pressure, if the completion of operations required pressure, directly using the corresponding tonnage nitrogen spring. If you do not know the total pressure, through calculating the die Zhongyuan cable springs with the total pressure calculated. At the same time, must be clear to the required pressure is the initial pressure(pressure)or the final pressure(full stroke), once we know these, can get the required total pressure. Find out the linear spring pressure of the most commonly used method is to consult the manufacturer's product pressure chart, through the chart, can know the mold line shaped spring specifications, colors, preload and stroke, can also be used as a spring pressure gauge.
2 installation of nitrogen spring
In most applications of nitrogen gas spring can be easily installed on the same core pocket used for spiral spring. The pocket depth, there should be a minimum of50% of the length of the gas spring, whichever is greater. In some applications can use the gas spring installation options, such as paste flange frame, at the base of the cylinder cover, and the thread body style. These options provide more flexibility in the existing mold using nitrogen gas spring.
When the size of the gas spring selected do not match, the spring being replaced by simple steps that can be taken, and then install pneumatic spring. Interval or sleeve can be used in the pocket, if the gas spring is smaller than the spring, or a gas spring may be mounted on the flange position. If the existing pocket is too shallow, it may be the core of deeper, if possible, or gas springs may be preloaded, to satisfy the space requirements.
Finally, a concern, the gas spring is installed using the fluid die. Direct exposure to certain die lubricant, coolant and the cleaner can be harmful gas spring and should be avoided. Shield gas spring from harmful liquid and providing adequate drainage system, the gas spring pocket.
3 How to nitrogen inflation?
In inflation before, to ensure that the piston rod is fully extended to the top, as in the case of no extension of the inflatable, will result in an incorrect position of the positioning ring. Using T type wrench is screwed into the piston head at the top of the screw, use appropriate tools top pressure inflating valve, so that the cylinder body of gas drained, forced upward pulling the piston rod, the piston sleeve and a positioning ring tightly.
4 nitrogen gas spring pneumatic
(1) the gas spring pneumatic requires the use of a special charging station or inflatable device. For independent if convenient transportation can be inflated, the seat board system of nitrogen spring side must be in the field of inflatable.
(2) the gas spring pneumatic pressure at 20 ℃, the standard pressure of 150(bar), if less than130bar inflatable, with ordinary nitrogen cylinders can be completed. Higher than that of 130bar are required to complete the air supercharging device.
(3) before the inflatable please confirm safety retainer ring is installed, and T type handle allows the plunger rod extends completely, adjust the desired inflation pressure value, inflation.
(4) when inflated, the air flow passes through the inflation valve speed not too fast, so as not to charge bad inflatable valve caused by leakage, after inflation with plug sealed inflatable mouth.Note: in the process of inflation must be safety operation, to pass safety training before, so as to avoid unnecessary harm.
