Abstract

The present invention relates to a double-acting water pump having a closed flow channel. According to the present invention, the double-acting water pump enables a flow channel, which is a route for supplying underground water, to be formed by a central flow channel, an inflow channel, and an outflow channel connected to communicate with each other in a central pipe, an inflow pipe, and an outflow pipe. Accordingly, interference between component and underground materials caused by external exposure of the flow channel can be prevented. Moreover, the flow channel can be formed using a pipe structure without having additional structures for the formation of the flow channel so that a compact structure can be easily performed.

Generally, the amphibious pump is installed underground so that the groundwater can be pumped, as shown in Fig.

One of these pumping pumps, several electric sampling devices in the form of an inertial pump have been developed to pump deeper groundwater from a small borehole. Typical examples are an inertial ball (Korean Patent No. 10-0770051) or an opening / closing unit (Patent Registration No. 10-1124075) have been used mainly for the purpose of pumping groundwater by up and down movement.

However, since the above-mentioned devices are unable to insert the iron core in the electromagnet due to the fact that the groundwater intake pipe is located at the center of the pump, the strength of the electromagnet is restricted. Therefore, There is a problem that sufficient power can not be provided.

In addition, since an inertial ball or an opening / closing unit is used, there is a problem that the amount of pumped water is very small.
