When starting a conventional suction horizontal shaft pump. In order to prevent the inlet from galling, the air inside the pump is removed using a vacuum cleaner, the pump is filled with water, and then the prime mover is started. however.

、これではポンプの構造が複雑となり，又ポンプ据付の
際の一般作業が極めて困難となる。When the removed water is sucked in from both the suction pipe and the discharge pipe,
The inilla is reversed by suction of water from the discharge pipe. When the pump was started, torque was applied to the inflator, which had been reversed, to suddenly rotate it in the forward direction, so there was a risk that the pump would be destroyed. Therefore, in order to prevent reverse rotation, a flap valve is provided at the tip of the κ discharge pipe to prevent water from being absorbed from the discharge pipe, but this complicates the structure of the pump and makes general work during pump installation extremely difficult.

を有するポンプおよびその運転方法を侵だものである。In order to eliminate this drawback, this problem was achieved by not providing a flat valve in the discharge pipe, but by providing an air intake port on the upstream side of the pump's inner lining, and replacing it with an intake valve. When the vacuum pump is connected with piping and a water level detector is installed at any point of the pump device and the communicating pipe, and the water level reaches the bottom end of the impeller in the pump casing at startup. This is used to start the pump, and water acts as a lubricant, allowing it to run safely without any risk of reverse rotation of the impeller. Furthermore, since the discharge pipe is not provided with a flap valve, it is extremely easy to hem the pump, which violates the advantages of the pump and its operating method.
