Technical Field

The present invention relates to an inverter booster pump system which can distinguish a mechanical seal of a pump, a check valve, an upper sleeve, water leakage of a suction and discharge head of the pump, water immersion of a machine chamber, and the like.

Background

Korean patent application publication No. 10-2018-0029634 (published 3/21/2018) describes a "method for sensing water leakage and flooding in a booster pump system".

The water leakage and immersion sensing method of the booster pump system comprises the following steps: judging whether a contact point sensor 1 mounted on a support plate 1 of a pump 1 is electrified or not; judging whether a contact point sensor 2 mounted on a support plate 2 of a pump 2 is electrified or not; judging whether a contact point sensor 3 mounted on a support plate 3 of a pump 3 is electrified or not; and through the combination of the electrification and the non-electrification of the contact point sensor, if the contact point sensor 1 is electrified, the contact point sensor 2 is electrified and the contact point sensor 3 is electrified, the whole booster pump system is judged to be immersed; if the contact point sensor 1 is electrified, the contact point sensor 2 is electrified and the contact point sensor 3 is not electrified, the water leakage of the pump 1 and the pump 2 is judged; if the contact point sensor 1 is electrified, the contact point sensor 2 is not electrified, and the contact point sensor 3 is electrified, the water leakage of the pump 1 and the pump 3 is judged; if the contact point sensor 1 is electrified, the contact point sensor 2 is not electrified, and the contact point sensor 3 is not electrified, the water leakage of the pump 1 is judged; if the contact point sensor 1 is not electrified, the contact point sensor 2 is electrified and the contact point sensor 3 is electrified, the water leakage of the pump 2 and the pump 3 is judged; if the contact point sensor 1 is not electrified, the contact point sensor 2 is electrified and the contact point sensor 3 is not electrified, the water leakage of the pump 2 is judged; if the contact point sensor 1 is not energized, the contact point sensor 2 is not energized, and the contact point sensor 3 is energized, it is determined that the pump 3 leaks water.

However, in the method for sensing water leakage and flooding of the booster pump system, the contact point sensor of the support plate is energized to determine water leakage of the pump, but it is impossible to sense which part of the pump leaks water.

Disclosure of Invention

Accordingly, an object of the present invention is to provide an inverter booster pump system capable of detecting water leakage in a portion where water leakage occurs most frequently in a pump, and capable of distinguishing water leakage in a mechanical seal of the pump, a check valve, an upper sleeve, a suction/discharge head of the pump, and water immersion in a machine room.

The inverter booster pump system according to the present invention for achieving the above object is characterized in that a plurality of support plates are disposed on a base, a pump is mounted on each support plate, a first groove and a second groove are formed in the support plates in a straight line shape, the first groove and the second groove are disposed facing each other around the pump, the second groove is disposed right under a convex side check valve, the upper end of a conduit is connected to an upper sleeve, the lower end of the conduit is disposed in the first groove, water leaking from the upper sleeve is supplied to the first groove through the conduit, a first contact point sensor is mounted in the first groove, a second contact point sensor is mounted in the second groove, signals from the first and second contact point sensors are supplied to a control unit, and the control unit determines whether water is leaking or flooding.

The control unit determines the water leakage pump and the water leakage position of the water leakage pump as shown in the following table.

X: power-off, O: is electrified

Accordingly, the inverter booster pump system according to the present invention has an effect in that not only the water leakage pump and the water leakage portion of the water leakage pump can be discriminated, but also the water leakage of the suction head and the discharge head and the water immersion of the machine room in which the pump is installed can be monitored.

The first and second contact point sensors 25 and 26 are maintained in a power-off state if the first and second tanks 21 and 22 are empty of water, and supply a power-on signal to the control unit by supplying a minute current to the water if the first and second tanks 21 and 22 are filled with water.

Unexplained reference numeral 71 denotes a suction head, and 72 denotes a discharge head.

According to the inverter booster pump system of the present invention configured as described above, if water leaks from the mechanical seal (not shown), the water leaking from the mechanical seal leaks to the outside through the upper sleeve 31. At this time, the water leaking from the upper sleeve 31 is supplied to the first groove 21 through the pipe, and if the first groove 21 is filled with the leaking water, the first contact point sensor 25 is energized, and an energization signal of the first contact point sensor 25 is supplied to the control portion.
