摘要： PURPOSE:To rapidly discharge foreign matter by detecting the pressure difference between the upstream and downstream sides of a filter element and irregularly and simultaneously changing a couple of backwash valves so that the pressure difference is controlled within specified values when the pressure difference exceeds a preset value. CONSTITUTION:A couple of filter elements 4A and 4B are provided in a circular- sectioned main casing 1. A couple of semicircular butterfly backwash valves 5A and 5B are furnished on the upstream side of the element to discharge the foreign matter deposited on the element. Meanwhile, a couple of discharge valves 6A and 6B are provided on the downstream side of the element. The pressure difference between the upstream and downstream sides of the elements 4A and 4B is detected, the backwash valves 5A and 5B are irregularly and simultaneously changed so that the pressure difference is controlled within specified values when the pressure difference exceeds a preset value, and the foreign matter is discharged outside the system from the discharge valves 6A and 6B. Consequently, foreign matter is rapidly removed from the cooling water line of a thermal power plant, etc.

摘要： PURPOSE:To detect leakage in the wall of a liquid storage tank without removing a liquid in the tank, by a method wherein the part where a leak is found is separated from the remaining liquid storage space, and a leak current is amplified, so that it is measured with a current flow meter. CONSTITUTION:A tank formed with side walls 1 and a bottom wall 2 of concrete, that is, a pool 2 is filled with water up to a liquid level 4. When, for instance, a damaged part exists in a lining 6, water in a detection box 20 leaks out in the side wall 1 through the damaged part 8. Consequently, there occurs a water current flowing out of the detection box 20 into an internal space 28 in the passage 31 of a nozzle 30. The current speed is measured by a detecting pointer 40 and a current flow meter 45 exposed to the current. In other words, the presence of a leak and its magnitude can readily be detected through the measurement of the current speed.
摘要翻译：目的：为了检测液体储罐壁上的泄漏，无需清除油箱中的液体，通过其中发现泄漏的部分与剩余液体储存空间分离并泄漏电流放大的方法，使得用电流流量计测量。构成：由侧壁1和混凝土的底壁2形成的罐，即池2，充满水直到液面4.当例如在衬里6中存在损坏部分时，检测箱20通过损坏部分8在侧壁1中泄漏。因此，发生从检测箱20流出的水流到喷嘴30的通道31中的内部空间28中。测量当前速度通过检测指针40和暴露于电流的电流流量计45。换句话说，通过测量当前速度，可以容易地检测泄漏的存在及其大小。
