这是篇国外marathon气动双隔膜泵的说明书,其中的疑难解答这一页很难翻译明白，说以寻求各位高手们帮帮忙，谢谢大家了！！

TROUBLESHOOTING
Possible Symptoms:
• Pump will not cycle.
• Pump cycles, but produces no flow.
• Pump cycles, but flow rate is unsatisfactory.
• Pump cycle seems unbalanced.
• Pump cycle seems to produce excessive vibration.
What to Check: Excessive suction lift in system.
Corrective Action: For lifts exceeding 20 feet (6 meters), filling the pumping chambers with liquid will prime the pump in most cases.

What to Check: Excessive flooded suction in system.
Corrective Action: For flooded conditions exceeding 10 feet (3 meters) of liquid, install a back pressure device.

What to Check: System head exceeds air supply pressure.
Corrective Action: Increase the inlet air pressure to the pump. Most diaphragm pumps are designed for 1:1 pressure ratio at zero flow.

What to Check: Air supply pressure or volume exceeds system head.
Corrective Action: Decrease inlet air pressure and volume to the pump as calculated on the published PERFORMANCE CURVE. Pump is cavitating the fluid by fast cycling.

What to Check: Undersized suction line.
Corrective Action: Meet or exceed pump connection recommendations shown on the DIMENSIONAL DRAWING.

What to Check: Restricted or undersized air line.
Corrective Action: Install a larger air line and connection. Refer to air inlet recommendations shown in your pump’s
SERVICE MANUAL.

What to Check: Check ESADS, the Externally Serviceable Air Distribution System of the pump.
Corrective Action: Disassemble and inspect the main air distribution valve, pilot valve and pilot valve actuators. Refer to the parts drawing and air valve section of the SERVICE MANUAL. Check for clogged discharge or closed valve before reassembly.

What to Check: Rigid pipe connections to pump.
Corrective Action: Install flexible connectors and a Warren Rupp Tranquilizer® Surge Suppressor.

What to Check: Blocked air exhaust muffler.
Corrective Action: Remove muffler screen, clean or de-ice and reinstall. Refer to the Air Exhaust section of your pump SERVICE MANUAL.

What to Check: Pumped fluid in air exhaust muffler.
Corrective Action: Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly. Refer to the Diaphragm Replacement section of your pump SERVICE MANUAL.

What to Check: Suction side air leakage or air in product.
Corrective Action: Visually inspect all suction side gaskets and pipe connections.

What to Check: Obstructed check valve.
Corrective Action: Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket. Refer to the Check Valve section of the pump SERVICE MANUAL for disassembly instructions.

What to Check: Worn or misaligned check valve or check valve seat.
Corrective Action: Inspect check valves and seats for wear and proper seating. Replace if necessary. Refer to Check Valve section of the pump SERVICE MANUAL for disassembly instructions.

What to Check: Blocked suction line.
Corrective Action: Remove or flush obstruction. Check and clear all suction screens and strainers.

What to Check: Blocked discharge line.
Corrective Action: Check for obstruction or closed discharge line valves.

What to Check: Blocked pumping chamber.
Corrective Action: Disassemble and inspect the welled chambers of the pump. Remove orfiush any obstructions. Refer to the pump SERVICE MANUAL for disassembly instructions.

What to Check: Entrained air or vapor lock in one or both pumping chambers.
Corrective Action: Purge chambers through tapped chamber vent plugs.PURGING THE CHAMBERS OF AIR CAN BE DLNGEROUS! Contact the Warren Rupp Technical Services Department before performing this procedure. Any model with top-ported discharge will reduce or eliminate problems with entrained air.
If your pump continues to perform below your expectations, contact your local Warren Rupp Distributor or factory Technical Services Group for a service evaluation.

WARRANTY
Refer to the enclosed Warren Rupp Warranty Certificate.

可能的症状：
•泵不转动。
•泵转动，但不产生任何流量。
•泵转动，但流率并不理想。
•泵转动似乎不平稳。
•泵周期似乎产生过大的波动。
如何检查：系统存在过度高度梯度。
纠正行动：高的超过20英尺（6米） ，可以通过先灌泵可以使得避免上述事故的发生
（待续）

如何检查：系统中流体吸力过度。
纠正行动：当流体条件超过10英尺（ 3米）的液体，安装回压装置。

什么检查：空气供应的压力系统最大值。
纠正行动：增加进气的压力泵。大部分泵片是在零流量专为1:1 压力比而设计的。

如何检查：空气供应的压力或体积超过系统的最大值。
纠正行动：根据已公布的性能曲线最为计算依据减少进气压力和体积向泵。通过快速循环泵会使流体鼓泡。

如何检查：不足吸力线。
纠正行动：达到或超过泵方面的建议，显示在二维图形。
（待续）

如何检查：受限或不足的空气线。
纠正行动：安装一个较大的空气线和连接。空气进气口的建议显示在您的泵的
服务手册上。

需检查的：检查钢管的连接 ，对外维修空调的分配制度水泵。
纠正行动：拆开检查的主要空气分配阀，试验阀和试验阀动。指以零件图和空气阀节服务手册。检查堵塞的放电或关闭阀前组装。

什么检查：刚性管道连接泵。
纠正行动：安装灵活的连接器和沃伦尼娜•鲁普镇定剂®电涌抑制器。

如何检查：阻止空气排气消声器。
纠正行动：删除消声器的画面，清洁或由冰和重新安装。指以排风区段，您泵服务手册。

如何检查：泵浦流体在空气中排气消声器。
纠正行动：拆开泵商会。检查为膈肌破裂或松散的膜片板大会。指以膈肌更换区段，您泵服务手册。

如何检查：吸力方漏风或空气中的产品。
纠正行动：视觉检查所有吸力方垫片和管道连接。

如何检查：阻挠止回阀。
纠正行动：拆开湿年底泵和手动赶走阻塞，在止回阀的口袋。指以止回阀节泵服务手册，供拆卸的指示。

如何检查：磨损或失调止回阀或检查阀座。
纠正行动：检查止回阀和座椅磨损和适当的座位。根据需要进行更换。指止回阀节泵服务手册，供拆卸的指示。

如何检查：封锁吸力线。
纠正行动：删除或冲洗阻塞。检查及清除所有的吸力屏幕和strainers 。

如何检查：阻止放电线。
纠正行动：检查阻塞或封闭放电线阀。

如何检查：封锁抽水厅举行会议。
纠正行动：拆开检查welled商会泵。删除orfiush任何障碍物。指泵服务手册，供拆卸的指示。

如何检查：夹杂气体或蒸气锁在一个或两个抽水商会。
纠正行动：清除商会通过挖掘商会发泄plugs.purging商会的空气可以dlngerous ！联系华伦尼娜•鲁普技术服务处前，表演了这个程序。任何模型与顶级端口放电将有助于减少或消除的问题，夹带的空气。
如果您的泵继续执行下面您的期望，请联络您当地沃伦尼娜•鲁普分销商或工厂的技术服务小组服务的评价。
