In general, a pump is a device that pumps the fluid upward and forcibly moves it when the fluid is below the discharge port, and is used to move or circulate the fluid.

Such a pump is required to completely fill the pump room at the initial stage of operation so that the pump is properly made. In the related art, a pump using another pump or a water-sealed vacuum pump that continuously operates while supplying a certain amount of water is operated. The pump is made by draining the air inside the pump room to make a vacuum and filling the water.

However, in the conventional pump and the water-sealed vacuum pump as described above, when pumping water containing a lot of sludge, the pumping water must be initially filled into the pump room.

That is, when air remains in the pump chamber, the vacuum pump is not properly made, there is a problem inferior workability.

In order to solve the above-mentioned problems, the present applicant has proposed a vacuum ferromagnetic suction pump which can smooth the vacuum pump of the fluid by forming the inside of the pump chamber in a vacuum state without initially filling water. .

By forcibly discharging to the outside to generate a pressure difference, it was possible to move the fluid pumped by the motor more easily to shorten the working time and to minimize the power consumption was able to improve the work efficiency.

However, the vacuum induction suction pump of the Korean Patent Registration No. 10-791044 proposed by the present applicant as described above, when the vacuum pump operation of the fluid is completed, to resume the operation, when the air is shut off the air Since the air blocking means is continuously blocked to maintain the vacuum state of the air discharge means, there was a problem that can not be carried out continuously because the initialization is not made.

That is, since the air blocking means does not open the air and maintains the closed state due to the vacuum state of the air discharge means, there is a problem that initialization is not properly performed.

The present invention has been proposed to solve the above conventional problems, and an object of the present invention is to improve the vacuum ferromagnetic pump of the present applicant Korean Patent Registration No. 10-791044, after the pump of the fluid is completed In addition, the present invention provides a vacuum ferromagnetic suction pump capable of smoothly initializing and facilitating rework.
