小能力驼峰 small capacity of hump

度影响蓄电池寿命和充放电能力，有少量的维护工作），占地面积较大。Subject to the limitation of natural climate conditions such as solar radiation intensity, sunshine hours and continuous rainy days, the battery with larger capacity should be equipped (ambient temperature affects battery life and charging and discharging capacity, and there is a small amount of maintenance work), occupying a larger area.

A、硅胶吸附能力很好，但遇液态水极易破碎，处理量大时又会很快失效，所以硅胶适用于处理量小而含水量不大的情况；Silica gel has a good adsorption capacity, but it is easy to be broken in the case of liquid water, and will fail quickly when the amount of treatment is large, so silica gel is suitable for the case of small amount of treatment and little water content;

B、活性氧化铝是较好的干燥剂，但活性丧失较快，特别在酸性气体较多时容易变质，需要经常更换吸附剂，成本也就增高；Activated alumina is a good desiccant, but the activity is lost quickly, especially in the acidic gas more easily deteriorated, often need to replace the adsorbent, the cost will increase;

C、分子筛是高效脱水剂，特别是抗酸性分子筛，能适应含酸性气体较多的天然气的脱水。分子筛特别适用于处理量大，而且要求露点降低幅度大的情况，如天然气液化前的深度脱水，在处理量小、露点降低要求不多的情况下就失去了它的优越性。Molecular sieve is an efficient dehydrating agent, especially acid resistant molecular sieve, which can adapt to the dehydration of natural gas with more acidic gas. Molecular sieve is especially suitable for the case of large treatment capacity and large dewpoint reduction, such as deep dehydration before natural gas liquefaction, but it loses its superiority when the treatment capacity is small and the dewpoint reduction requirement is few.

D、以上都不对

A、起点流量变化很小，近似认为不变，终点流量随昼夜用气量的不同变化较大。Q1变化幅度＜q2变化幅度the change of the starting flow is small, and it considered to be invariable approximately. amplitude q1 less than＞ B、末段起点的最高压力等于或小于最后一个压气站的出口压力p1max。The maximum pressure at the beginning of the terminal is equal to or less than the outlet pressure p1max of the last compressor station.

C、末段终点的最低压力p2min应不低于配气站所要求的供气压力。末段的压力变化范围决定了末段的储气能力。The lowest pressure p2min at the end of the terminal shall not be lower than the gas supply pressure required by the distribution station. The pressure range of the terminal determines the gas storage capacity of the terminal.

D、输气管末段的气体处于不稳定流动状态，为简化起见，下面的讨论与计算是以稳定流动状态为基础的，以连续替换法作近似计算，计算结果其储气能力比实际小10~15%。The gas at the end of the gas pipeline is in an unsteady flow state. For the sake of simplification, the following discussion and calculation are based on the stable flow state, and the continuous replacement method is used for approximate calculation. The calculated result shows that the gas storage capacity is 10~15% less than the actual value.

A、比实际输气量小10%左右It is about 10% smaller than the actual volume；

B、适用于阻力平方区Apply to the resistance square；

C、适用于管径较小，输气量不很大，净化较差的矿场集输或干线输气It is suitable for gathering and transporting gas in the mine with small pipe diameter, small gas transmission capacity and poor purification.

D、适用于水力光滑区Suitable for hydraulic smooth zone

RTU阀室用电负荷很小（537W），供电质量和负荷等级高，且均处于偏远地区，外电源供电质量和供电可靠性难以满足负荷供电要求时，须选用可靠的自备电源：太阳能电源或小容量天然气发电装置（均带有不同容量的蓄电池）等供电设备，以确保其不间断供电的要求。RTU valve chamber electricity load is small (537 w), high quality of power supply and load grade, and are in remote areas, the quality of power supply and power supply reliability meets the requirement of load power supply, should choose reliable energent power: solar power or small capacity of gas power generation device (all with different capacity of battery) and other power supply equipment, to ensure the uninterrupted power supply requirements.
