DEEP WELL PUMP CONTROL

　　ACV 513-6泵控制阀在泵启动期间开始处于开启的状态，将深井中的气体和碎片清除到大气中。阀门受到控制的关闭操作，开启主管线止回阀，逐渐增加管线压力。在关闭周期内，阀门将重新开启，以逐渐降低管线压力，防止出现冲击现象。通过限制开关总成，阀门和泵的运行是相互作用，相互影响的。
　　The ACV 513-6 pump control valve starts in an open position during pump start-up, purging the deep well of air and debris to atmosphere. Controlled closing of the valve, opens the mainline check valve, gradually increasing line pressure. The valve reopens during shut-down cycle to gradually decrease line pressure and prevent shock. Valve and pump operations are interlocked by a limit switch assembly.

需要考虑的因素
Points to consider:

• 参阅技术参数 - 流量表
  Refer to Engineering Data – Flow Capacity Chart
• 深井泵阀的选型必须使其排放大气泵的排放压力超过平常系统的静态压力。这一点很必要，可以防止主管线止回阀过早开启。参阅技术参数 - 压降表。如果流速超过45英尺/秒，则采用更大的阀门。
  The deep well pump valve must be sized so it relieves atmosphere pump discharge pressure in excess of the normal system static pressure.
  This is necessary to prevent premature opening of the main line check valve. Refer to engineering Data - Pressure Drop Chart. If flow velocity exceeds 45 feet per second use next larger valve
• 所需流量的压降
  参阅技术参数 - 压降表
  Pressure drop at required flow
  Refer to Engineering Data – Pressure Drop Chart
