JPH05126035A - Magnetic pump for leading fluid in and out - Google Patents

Abstract

PURPOSE:To transfer a fluid efficiently by providing a piston in a pressure-tight cylinder, and reciprocating the piston by a magnetic force so as to lead in and lead out the fluid in the cylinder. CONSTITUTION:A piston 2 is provided in a pressure-tight cylinder 1, and the piston 2 is reciprocated by a magnetic force. In the right side chamber 1R of the pressure-tight cylinder 1, a check valve type right side discharge valve 3 and a right side suction valve 4 are communicated and connected. On the other hand, also in the left side chamber 1L of the cylinder 1, a check valve type left side discharge valve 7 and a left side suction valve 8 are communicated and connected. The left side discharge valve 7 and a fluid leading-out port 5, and the left side suction valve 8 and a fluid leading-in port 6 are communicated and connected respectively. As a result, a sealed container can be applied as the cylinder 1, and no leakage is generated even though no sealing member or the like is used. The suction and the discharge can be carried out continuously following the constant reciprocation of the piston 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic pump device for fluid inflow and outflow for quantitatively transferring a fluid such as gas or liquid at high pressure.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
As a pump for quantitatively transferring a fluid at high pressure,
Plunger pumps, diaphragm type plunger pumps, etc. are available. The plunger pump always leaks a small amount from the gland packing during operation. In addition, the diaphragm type plunger pump has a diaphragm made of thin metal or Teflon resin, etc.Since this diaphragm is operated while continuously deforming, damage and leakage due to fatigue of the diaphragm cannot be avoided, It needed to be replaced. Therefore, there is a problem that they are dangerous to use in flammable and toxic fluids because they all have a problem of leakage.

In addition, these pumps are provided with only one set of check valves (one for intake and one for discharge) for operating the piston mechanically from the outside, and therefore, the fluid is generated by the piston. Do not eject liquid while inhaling. Therefore, the pump also has a problem that pulsation occurs.

The applicant of the present invention can completely prevent fluid from leaking by reciprocating the piston by the magnetic force of the magnet. Moreover, depending on how the check valve is installed, the function of two plunger pumps can be achieved. The present invention has been completed focusing on the fact that two pistons can be used.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

[0006] A piston 2 is arranged in a pressure-resistant cylinder 1, a fluid is introduced into the cylinder 1 by reciprocating the piston 2 by a magnetic force, and a fluid is drawn in and out from the cylinder 1. In the right chamber 1R of the pressure-resistant cylinder 1, a check-type right discharge valve 3 and a check-type right intake valve 4 are provided in communication with each other, and the right discharge valve 3 and the fluid outlet 5 are connected.
And the right suction valve 4 and the fluid inlet 6
And the left chamber 1L of the cylinder 1 are also connected to a check type left discharge valve 7 and a check type left suction valve 8 so that the left discharge valve 7 and the fluid outlet port are connected to each other. The present invention relates to a magnetic fluid pumping device for fluid inflow / outflow, which is characterized in that the left suction valve 8 and the fluid introduction port 6 are in communication with each other.

[0007]

When the piston 2 moves rightward in the drawing due to the magnetic force (see FIG. 1), when the fluid from the fluid introduction port 6 is introduced into the left chamber 1L of the cylinder 1 through the left suction valve 8. At the same time, the fluid in the right chamber 1R of the cylinder 1 flows into the right discharge valve 3
It is led out to the fluid lead-out port 5 via.

When the piston 2 moves to the left in the drawing due to the magnetic force (see FIG. 2), the fluid from the fluid inlet 6 is introduced into the right chamber 1R of the piston 1 through the right suction valve 4. At the same time, the fluid in the left chamber 1L of the cylinder 1 is discharged to the fluid discharge port 5 via the left discharge valve 7.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show one embodiment of the present invention.
This will be described below.

The right discharge valve 3, the right intake valve 4, the left discharge valve 7, and the left intake valve 8 shown in the drawing are known check valves, and the cylinder 1 is constructed to withstand high pressure.

Reference numeral 9 is a ring-shaped external magnet which reciprocates along the outer circumference of the cylinder 1 by an appropriate means.

In the drawing, the right chamber 1R of the cylinder 1, the right discharge valve 3, the right intake valve 4 and the left chamber 1L of the cylinder 1, the left discharge valve 7, the left intake valve 8 are connected by T-shaped branch pipes 10 and 11. Connect with each other,
A pipe line 12 that connects the right discharge valve 3 and the fluid outlet port 5 and a left discharge valve 7 that communicates with the pipe line 13, and a pipe line 14 that connects the right intake valve 4 and the fluid inlet port 6 to each other. The left suction valve 8 and the left suction valve 8 communicate with each other through a pipe line 15.

[0013]

Since the present invention is constructed as described above, it has the following effects.

Since the piston is actuated by magnetic force without being mechanically operated, the piston rod and the like are not required, and therefore, a closed container can be adopted for the cylinder, and therefore, leakage does not occur even if a sealing material or the like is not used. It becomes a magnetic pump device for fluid inflow and outflow.

Since the suction and the discharge are continuously performed with the reciprocating movement of the piston, that is, when one side of the pump is performing the suction operation, the opposite side is performing the discharge operation, and the discharge operation is always performed. Therefore, a magnetic pump device for fluid inflow and outflow in which pulsation is reduced can be provided, and a single pump according to the present invention can transfer fluid for two conventional pumps.

As described above, the present invention provides a magnetic pump device for fluid inlet / outlet which is very efficient.
