| * 需要适当的机械设备。 注意:在泵排泄口,首选的止回阀是管内弹簧负载,带杠杆和压铁或杠杆和弹簧的旋启式止回阀。止回阀应该安装在离泵尽可能远,或至少5倍管道直径的的位置。可能需要流向矫直装置。 * Proper machining facilities required. Note: On pump discharge, the preferred check valves are an in-line spring loaded, swing design with lever and weight or lever and spring. You should also install the check valve as far from the pump as possible and at a minimum length of 5 times the pipe diameter. Flow straighteners may be required. |
