An air discharge pipe is communicated with one side of the pump room. An air discharge pipe has an open and close valve(5) to control the air flow. A reservoir is inserted between the vacuum pump and air discharge pipe.

Description

Vacuum self-priming pump

The present invention relates to a pump mainly used for pumping water in reservoirs, dams and submerged ponds, and more particularly, in a vacuum pump having a pump chamber in which fluid is pumped by a motor, the air for discharging air in the pump chamber to the outside. By installing a discharge means for forcibly discharging the air in the pump chamber to the outside to generate a pressure difference, and more particularly relates to a vacuum magnetic induction pump that is simple in structure and economically applicable.

 Generally, pumps for pumping water are installed in reservoirs, dams and flooded areas to pump water as needed.

Such 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 pumps are generally designed to be pumped only when water is completely filled into the pump chamber of the pump at the beginning of operation. Conventionally, the air in the pump chamber of the pump is manually sealed or sealed by using a sealed vacuum pump that continuously supplies a certain amount of water. It was possible to pump by draining the water to make the water while making a vacuum.

In addition, when the water is circulated, the temperature of the water rises, bubbles are generated, and pumping is not performed smoothly by the bubbles, so that a separate water tank was installed to lower the water temperature.

In addition, the large-capacity mobile pump cannot use a manual or water-sealed vacuum pump, so the main pump needs to be filled with another pump, thereby increasing installation and operating costs.

However, the conventional pump and the sealed vacuum pump as described above had a problem in that the pumping is not easily performed by the sludge contained in the water when pumping water containing a lot of sludge.

In order to solve the above-mentioned conventional problems, the present inventor proposes Korean Patent Registration No. 10-791044 (name: vacuum ferromagnetic pump) to draw air from the pump chamber by the air discharge means of the vacuum pump. By discharging to the outside, the fluid was moved more easily and the work efficiency was improved.

As described in Korean Patent Application No. 10-791044, the vacuum ferromagnetic pump of the present applicant has a pump chamber consisting of a motor and a space of a predetermined size, and is connected to a rotating shaft of the motor to rotate the fluid at the inlet. In the pump having a body in which the impeller is embedded to suck the discharge to the discharge port; An air discharge pipe communicating with the pump chamber of the body to move the air of the pump chamber, an air blocking portion installed between one end of the air discharge pipe and the body pump chamber to open and close one end of the air discharge pipe; and the other end of the air discharge pipe And an air discharge means having an air pumping part communicating with the air pump to discharge the air in the body pump chamber to the outside, and making the body pump chamber in a vacuum state to lift the fluid upward.

However, it is difficult to apply the vacuum ferromagnetic pump of the present inventors to a conventional pump installed and installed, which is the air discharge means and the vacuum pump is integrated, it is almost impossible to apply to the existing pump There was a difficult problem to apply.

Accordingly, in order to solve the problem of the vacuum ferromagnetic pump having the above problems, the present cause makes it easy to configure and apply the air discharge means without largely damaging the existing pump, the pump chamber inside By forcibly discharging the air to the outside to generate a pressure difference, it was possible to more easily move the fluid pumped by the motor to provide a vacuum magnetic suction pump that can improve the work efficiency while reducing the working time.

The present inventors improved the vacuum magnetic induction pump as described in Korean Utility Model Registration No. 20-441268 (name: vacuum magnetic induction pump), as described in the publication has a pump chamber consisting of a motor and a space of a predetermined size A conventional pump having a body in which an impeller is embedded to rotate in connection with a rotating shaft of a motor to suck a fluid at an inlet and discharge to a discharge port; A one-way check valve is installed at the discharge port of the body, and an air discharge pipe is installed to communicate with the pump chamber so that the air in the pump chamber is moved. An air blocking unit provided with a buoy to open and close and a detection sensor for detecting whether the opening and closing is provided, and is connected to the other end of the air discharge pipe pumping having a space of a predetermined size therein to discharge the air of the body pump room to the outside A diaphragm disc installed inside the seal and the pumping chamber, a rod for linearly reciprocating the diaphragm disc, an eccentric wheel inserted and rotated on an inner circumferential surface of the rotating ring provided on the rod, and an eccentric wheel having an axis fixed therein; An air pumping means comprising a rotating motor to which the pumping chamber is fixed is provided. It may consist of.

While shortening, the efficiency of the work was improved.

However, the conventional Korean Utility Model Registration No. 20-441268 No. 20-441268 vacuum ferromagnetic pump of the present applicant has a complicated structure of the air discharge means, difficult to manufacture and high production cost has an uneconomical problem.
