美国OFI滚子炉老化罐FITE型老化室供应
OFITE老化室是一种(美国编号压力容器，使样品能够承受高于水沸点的温度，并且仍然保持在液体状态。该电池可用于静态温度暴露或在预置的蕞低老化时间为16小时的滚筒烤箱中处于动态模式。
OFITE老化电池有260 mL和500 mL大小，使用Viton和Teflon o型密封件。老化电池通常由不锈钢制造(303级或316级)，用于高温测试(高达500°F/260°C)。

Carefully inspect the o-ring for defects and place it in the groove in the cell body. Replace the o-ring if it is hard or has cuts and nicks. Blow air through the valve stem to make sure it is not plugged.Determine a safe volume and safe initial pressure for the temperature at which the sample will be tested (refer to the chart on page 5). Place the correct volume of fluid into the cell. Be careful not to get fluid in the o-ring groove or on the o-ring.Clean any spilled fluid from the edge of the cell and place the inner cap on top of the cell body o-ring so that it seats in place. Hand tighten the outer cap in place. Using the Allen wrench, tighten the set screws in the outer cap. Insert the valve stem with the o-rings in place into the inner cap and tighten completely. Loosen the valve stem approximately one half turn before pressurizing.
仔细检查O形圈是否有缺陷，并将其放入单元体的槽中。如果O形圈很硬或有切口和刻痕，请更换。将空气吹入阀杆，确保其没有堵塞。确定安全体积和安全初始压力，以测试样品的温度(参考第5页的图表)。将正确体积的液体放入试管中。小心不要让油液进入O形圈槽或O形圈。清洁单元边缘溢出的油液，并将内盖放在单元体O形圈顶部，使其就位。用手将外盖拧紧到位。使用内六角扳手，拧紧外盖中的定位螺钉。将带有O形圈的阀杆插入内盖并完全拧紧。在加压之前，松开阀杆大约半圈。美国OFI滚子炉老化罐175-50OFITE型老化室供应

When the desired pressure is reached, close the valve stem by tightening it with a wrench. To ensure there are no leaks, immerse the cell in water and check for any bubbles coming from the valve stem or cell cap.Place the Aging Cell inside the oven and adjust to the desired tempera- ture.After the desired aging time has elapsed, remove the cell from the oven and allow it to air cool until the sample temperature is 300°F (149°C) or less. The cell may then be either air or water cooled.
达到所需压力后，用扳手拧紧阀杆，关闭阀杆。为确保无泄漏，将电池浸入水中，检查阀杆或电池盖上是否有气泡。将老化电池放入烤箱内，并调节至所需温度。在所需老化时间结束后，将电池从烤箱中取出，让其空气冷却，直到样品温度达到300°F(149°C)或更低。s.电池可以是空气冷却的，也可以是水冷却的。
The sample temperature must be equal to the ambient temperature before you release the pressure and open the cell.Loosen the set screws, unscrew the outer cap, and remove the inner cap.Clean out the valve stem with water. Blow air through the stem to remove any residual water.Observe the aged fluid and record the condition as “fluid”, “gelled”, “plas- tic”, “hard”, etc. You may also want to test for viscosity, shear or gel strength, or filtration control.Thoroughly clean the entire cell with soap and water.
在释放压力和打开单元之前，样品温度必须等于环境温度。松开定位螺钉，拧下外盖，然后拆下内盖。用水清洗阀杆。将空气吹过阀杆，以除去任何残留的水。观察老化的液体并将其记录为“流体”、“凝胶”、“Prasic”、“硬”等。还可以测试粘度、剪切或凝胶强度或过滤控制。用肥皂和水彻底清洗整个电池。
Regular maintenance will extend the useful life of the aging cells.After every test: 1. Thoroughly clean and dry all components inc the cell body, inner cap, outer cap, valve stem, and o-rings. 2. Inspect all o-rings for damage or wear. Discard any that are nicked, cracked, or distorted from their original shape. Replace them with new o-rings. 3. Apply grease to the threads on the outer cap and cell body. Every three years (yearly for highly corrosive conditions): 1. Sand blast the metal components (cell body, inner cap, outer cap). 2. Visually inspect the cell body and inner cap for pitting or other signs of corrosion. If any material loss is present, replace the damaged com- ponent. 3. Inspect the threads on the outer cap and cell body for burrs. 4. Replace all o-rings and apply grease to the threads on the outer cap and cell body. 5. Pressure test with water up tpsi. OFITE offers aging cell recertification that includes all of the above plus a one-year certificate. Contact your sales representative for more information.美国OFI滚子炉老化罐175-50OFITE型老化室供应
定期维护可延长老化电池的使用寿命。每次测试后：1。彻底清洁和干燥所有部件，包括单元体、内盖、外盖、阀杆和O形圈。2。检查所有O形圈是否损坏或磨损。丢弃任何从原始形状上刻痕、裂纹或变形的物体。更换新的O形圈。三。在外盖和单元体的螺纹上涂抹润滑脂。每三年一次(高度腐蚀条件下每年一次)：1.对金属部件(电池体、内盖、外盖)进行喷砂处理。2。目视检查电池体和内盖是否有点蚀或其他腐蚀迹象。如果存在任何材料损失，更换损坏的部件。三。检查外盖和电池体上的螺纹是否有毛刺。4。更换所有O形圈，并在外盖和单元体的螺纹上涂抹润滑脂。5。水压试验，蕞高4000 psi。OFITE提供老化细胞再认证，包括上述所有认证和一年的证书。有关更多信息，请与您的销售代表联系。
