MVME177-016工控机器人备件
蒸汽监测系统必须由合格的工程师或技术人员按照公认的惯例进行设计和安装。井必须防止交通堵塞，永久标记为“监测井”或“测试井无填充物”，并配有锁帽，在不使用时必须锁紧，以防止未经授权的进入和篡改。蒸汽监测只能在以下条件下使用：（i）开挖区的土壤必须具有足够的多孔性，以允许蒸汽从储罐移动到蒸汽传感器。砾石、粗砂和碎石是多孔土壤的例子；（ii）放置在储罐中的储存物质或示踪化合物必须具有足够的挥发性，以便蒸汽传感器能够检测到；（iii）蒸汽监测不得受到地下水、降雨或土壤湿度的阻碍，以致泄漏可能在30天以上未被发现；（iv）背景污染不得掩盖或干扰释放的检测；6 NYCRR第598部分–2015年10月11日第13页，共35页598.6（b）（v）系统必须设计和运行，以检测高于背景水平的蒸汽增加。每周必须至少进行一次监测；以及（vi）蒸汽监测井的数量和位置必须足以确保检测储罐任何部分的泄漏，并且必须基于科学研究。井的直径必须至少为4英寸。（4） 可使用由合格工程师或技术人员设计和安装的地下水监测井。井必须防止交通堵塞，永久标记为“监测井”或“测试井无填充物”，并配有锁帽，在不使用时必须锁紧，以防止未经授权的进入和篡改。地下水监测只能在以下
条件下使用：（i）储存的物质必须与水不混溶，且比重小于1；（ii）地下水位必须距地面小于20英尺。储罐和井之间土壤的水力传导率不得低于百分之一厘米/秒。砾石和中粗砂是此类土壤的例子；（iii）井套管的开槽部分必须设计成防止土壤迁移到井内，并且必须允许危险物质在高和低地下水条件下进入井内；（iv）井的直径必须至少为4英寸，并从地面到过滤组件顶部进行密封，以防止地表水进入井内；（v） 井必须位于开挖区内或在技术上可行的范围内；（vi）监测方法必须能够探测到地下水顶部至少八分之一英寸的游离产物。必须每周进行一次监测；以及（vii）地下水监测井的数量和位置必须足以确保检测到储罐任何部分的泄漏，并且必须基于科学研究。（5） 如果自动储罐计量设备能够检测到每小时十分之二加仑或更大的泄漏，检测概率为95%，误报概率为5%或更低，并且在一小时内宣布泄漏十分之一加仑的最大阈值，则可以使用自动储罐计量设备。每周必须进行一次监测。（6） 部门批准的其他等效方法，如果该方法能够检测到每小时十分之二加仑的泄漏，检测概率为95%，误报概率为5%。6 NYCRR第598部分–10月。
The steam monitoring system must be designed and installed by qualified engineers or technicians in accordance with recognized practices. The well must be protected against traffic jams, permanently marked as "monitoring well" or "test well without filling", and equipped with a lock cap, which must be locked when not in use to prevent unauthorized entry and tampering. Steam monitoring shall only be used under the following conditions: (i) The soil in the excavation area must be sufficiently porous to allow steam to move from the storage tank to the steam sensor. Gravel, coarse sand and gravel are examples of porous soils; (ii) The stored substance or tracer compound placed in the tank must be sufficiently volatile to be detected by the vapor sensor; (iii) Steam monitoring shall not be impeded by groundwater, rainfall or soil moisture so that leakage may not be detected for more than 30 days; (iv) Background contamination shall not mask or interfere with the detection of releases; 6 NYCRR Part 598 – October 11, 2015 Page 13 of 35 598.6 (b) (v) The system must be designed and operated to detect an increase in steam above the background level. Monitoring must be carried out at least once a week; And (vi) the number and location of steam monitoring wells must be sufficient to ensure detection of leaks in any part of the tank and must be based on scientific research. The diameter of the well must be at least 4 inches. (4) Groundwater monitoring logs designed and installed by qualified engineers or technicians can be used. The well must be protected against traffic jams, permanently marked as "monitoring well" or "test well without filling", and equipped with a lock cap, which must be locked when not in use to prevent unauthorized entry and tampering. Groundwater monitoring can only be conducted in the following areas
Under the following conditions: (i) The stored substance must be immiscible with water and its specific gravity is less than 1; (ii) The groundwater level must be less than 20 feet above the ground. The hydraulic conductivity of the soil between the tank and the well shall not be less than one hundredth of a centimeter per second. Gravel and medium coarse sand are examples of such soils; (iii) The grooved part of the well casing must be designed to prevent soil migration into the well, and must allow hazardous substances to enter the well under high and low groundwater conditions; (iv) The well must be at least 4 inches in diameter and sealed from the ground to the top of the filter assembly to prevent surface water from entering the well; (v) The well must be located in the excavation area or within the technically feasible range; (vi) The monitoring method must be able to detect free products at least one eighth of an inch above the top of the groundwater. Monitoring must be carried out once a week; And (vii) the number and location of groundwater monitoring wells must be sufficient to ensure that any part of the tank leaks are detected, and must be based on scientific research. (5) Automatic tank gauging equipment may be used if it can detect a leak of two tenths of a gallon or more per hour, with a detection probability of 95%, a false alarm probability of 5% or less, and a maximum threshold of one tenth of a gallon of leakage is declared within one hour. Monitoring must be carried out once a week. (6) Other equivalent methods approved by the department, if the method can detect the leakage of two tenths of a gallon per hour, the detection probability is 95% and the false alarm probability is 5%. 6 NYCRR Part 598 – October.
