If the cylinder is to be dismantled for any length of time, coat the metal parts, which are to be reused with a good rust inhibitor and store them in aprotected area.Disassembling the Cylinder1. Un-thread the top screw on the rear cap (#23).2. Remove the rear cap.3. Drain the oil inside.4. Knock the trunnion (#31) to force the inner piston rod (#32) out.5. Take out the piston rod (includes a larger and smaller one).6. Knock the inside edge of the piston rod to find the correct position of the inner support ring.7. Remove the support ring.8. Punch holes into the back of the inner groove.9. You may also drill holes with a power drill.10. Rotate the inner back-up ring hole at an angle (using the process above) to remove the innerback-up ring (#9).11. Take out the two piston rods inside.12. Repeat steps 8, 9, and 10. Remove the back-up ring (#9) from the larger piston rod.13. Take out the smaller piston rod.14. Remove the #8, the #16, and the #19 BS seals from the larger and smaller piston rod.15. The #18 back-up ring is at the other end of the piston rod. See the image below.Reassembly Procedures1. Place the 3rd stage tube (#2) back inside the outer tube assembly (#1) and install the collar (#6).2. Place the 2nd stage tube (#3) inside the 3rd stage tube (#2) and install the collar (#7).3. Re-thread the rod end (#13) onto the 1st stage tube (#4) and put the 1st stage tube (#4) into thecylinder. Be careful not to damage the seals while installing each tube.4. Thread the rear cap (#23) onto the cylinder and tighten the hex set screw (#26).Operating Conditions•The maximum operating pressure must not exceed 2500 PSI.•The contamination level of the oil must not exceed 16/13/10 from the ISO standard 4406. •The acceptable temperature range is -40° F to 200° F.Formula for Calculating the Initial Required Cylinder Force to Lift a Load:A = the distance from the center of the load to the center of the dump body hinge pin (inches)B = the length from the center of the cylinder base pin to the center of the dump body hinge pin (inches)Load (lb.) x A /B = Initial required cylinder force (lb.)Example:50,000 (lb.) x 85"/166” =25,602 lb. = Initial required force (lb.)B = The length of cylinder base pin to body hinge pin D = Dump Angle CoefficientB X D = Approximate Required StrokeExample:166(B) X 845(D)= 140 Approximate Required Stroke•When the cylinder is not in use it should be fully retracted to prevent the chromed cylinder shaft from becoming damaged.•Always store the cylinder inside to protect it against harsh weather conditions.•Fill the cylinder with oil to prevent internal corrosion caused by air condensation. Tilt the cylinder to make sure that all seals are completely in contact with the oil to avoid any prematuredeterioration of the seals.•Cover any unpainted part with a rust inhibitor to avoid corrosion.•Regularly grease the trunnion pins. The time between greasing will be dependent on the amount the cylinder is used. Improper lubrication will result in the pins wearing prematurely.•For replacement parts and technical questions, please call Customer Service at 1-800-222-5381. •Not all product components are available for replacement.

传统BOD5的测定方法采用化学稀释法。
该方法操作繁琐，对分析人员的实验技能要求较高，实验数据的离散性较大，往往造成无法得出准确的实验结果。
870型直读式BOD5测定仪是利用空气压差法进行生化需氧量测定的一种新型仪器，其操作简单，能提供与化学稀释法可比的准确测量结果，读数直观，使用和维护方便。
广泛应用于环保监测、石油化工、医疗卫生、教学科研等部门对水质的监测，是广大分析工作者的有力工具。
二、工作原理1、B0D5基本原理生化需氧量（英文缩写BOD），是指在特定条件下，通过水中需氧微生物的繁殖和呼吸作用，分解水中有机物质时所消耗或所需要溶解氧量。
水中的BOD5值通常以样品在20℃放置5天所消耗溶解氧的量(mg/L数)表示，记为“BOD5”。
2、测定原理将预先选好量程并按量程范围量好体积的水样倒入培养瓶中，在主机搅拌器上连续搅拌。
并将主机和培养瓶放入培养箱中。
调节培养箱内温度为20℃±1℃，待样品恒温后进行五日培养。
培养瓶中的水样在连续搅拌的情况下保证了足够的溶解氧供微生物进行生化反应。
水样中的有机物经过生物氧化作用，转变成氮、碳和硫的氧化物。
在这一过程中，从水样中溢出的唯一气体二氧化碳被氢氧化钠(或氢氧化钾)吸收。
此时，培养瓶中空气压力减少量，相当于微生物所消耗的溶解氧含量，即水样BOD5值与瓶中空气压力减少的程度成正比，所以BOD5的值可以由空气压力减少值来测定，增加或减少所取样品的量可以增加或降低压力减少值。
