8）利用RO前置泵给水压力，使水通过高压泵进入反渗透组件数分钟，以排除组件及管路的空气。关闭RO膜进水压力控制阀。 10）再次确定浓水控制阀是位于打开位置。 11）缓慢地打开进水压力控制阀（进水压力低于0.4Mpa）。 12）启动高压泵。 13）慢慢地打开进水压力控制阀，增加进水压力和进水流量直至设计值，但升压速度必须低于0.07Mpa/秒，继续让所有产水和浓水排入合适的排放水收集处。 14）缓慢地关闭浓水压力控制阀直至产水与浓水之比接近设计比，但不要超过设计比（即回收率）。检查系统压力以确保不超过设计上限。重复步骤9和10直到系统达到设计的产水量和浓水量。 16）本装置停止时，首先要逐渐打开高压浓水阀门。逐渐降低工作压力，注意关机时严禁突然降压，避免卷式反渗透膜元件损坏。关闭所有阀门时，注意让反渗透膜组件内充满水。 17）关闭电导率仪仪表的电源和电源总开关。关闭预处理系统各设备。 18）RO系统工作方式：将电源开关处于“开”位置，前置泵开关“自动”位置，高压泵开关处于处于“开”位置，主机冲洗处于“关”位置，系统自动启动。在原水水箱低水位或RO纯水箱高水位时 RO系统自动停止工作，处于待机状态。恢复后RO系统自动启动。

Instructions reverse osmosis membrane (B) 8) the use of pre-RO water pressure pump, high pressure pump through the water a few minutes into the reverse osmosis components, components and piping to eliminate air. Close RO membrane inlet pressure control valve. 10) again to determine the concentration of the water control valve is in the open position. 11) Slowly open the inlet pressure control valve (inlet pressure is lower than 0.4Mpa). 12) Start the high pressure pump. 13) Slowly open the inlet pressure control valve to increase water pressure and water flow rate until the design value, but boost the speed must be less than 0.07Mpa / sec, to allow all water production and dense water into water suitable for discharge collection Department. 14) Slowly close the concentrate control valve until the pressure of water production and the concentration ratio close to the design than the water, but do not exceed the design ratio (ie recovery). Check the system pressure to ensure that does not exceed the design limit. Repeat steps 9 and 10 until the system reaches its design capacity of water and concentrated water. 16) The device is stopped, the first high concentration of water to gradually open the valve. Gradually reduce the pressure of work, attention suddenly forbidden to step off to avoid damage to spiral reverse osmosis membrane elements. Close all valves when attention is paid to the reverse osmosis membrane module filled with water. 17) Turn off the power meter and conductivity meter power switch. Close pretreatment system equipment. 18) RO system works: The power switch is "ON" position, the front pump switch "Auto" position, high pressure pump switch is "on" position, flush the host in the "off" position, the system automatically starts. Low water level in the raw water tank of pure water tank high water or RO RO system will automatically stop working when in standby mode. Automatically start after the resumption of the RO system.
