1 is a piping diagram of a high-pressure pump apparatus according to an embodiment of the present invention,
2 to 4 are schematic diagrams of piping for explaining embodiments of the present invention.

A high pressure pump apparatus (hereinafter, referred to as 'high pressure pump apparatus') 100 for a plurality of spray nozzles according to an embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 1 is a piping system diagram of a high-pressure pump apparatus according to an embodiment of the present invention, and FIGS. 2 to 4 are piping system diagrams for explaining embodiments of the present invention.

1, the high-pressure pump apparatus 100 includes a motor module 110 that provides a driving force; A pump module 130 coupled to the motor module 110 so as to pressurize the fluid with a suction port 135 through which the fluid flows and a discharge port 137 through which the pressurized fluid is discharged; A storage tank 190 for storing the fluid and supplying the fluid to the inlet 135; A supply line 150 having a plurality of spray lines 160 having a plurality of spray nozzles 165 communicating with the discharge ports 137 and capable of spraying a fluid into fine particles; And a bypass line 140 recovered from the pump module 130 to the storage tank 190 while maintaining a predetermined pressure of the nozzle 165. With this configuration, the fluid pressurized at a high pressure can be continuously and continuously supplied to the nozzle 165. [ For example, when a high-pressure fluid is continuously operated by a nozzle 165 for forming a fine mist on the evaporator side of the air conditioner for constant temperature and humidity, the high-pressure fluid is circulated to the evaporator side of the air- It can be stably and continuously supplied to the high-pressure pump apparatus 100 of the present invention.

The motor module 110 includes a motor 113 for providing a rotational force by an external power source and a control unit 115 for controlling the operation of the motor 113. The control unit 115 preferably includes an interverter or the like that interlocks with various valves and pressure gauges to be described later and controls the rotational speed of the motor 113. [ The motor module 110 is cooled by the cooling unit 143 branched at the bypass line 140 as described later and is heated by the heat generated in the process of operating continuously to form a high pressure in the motor module 110 Can be removed.

That is, the high-pressure fluid is sprayed from the nozzle 165 and the fluid pressurized to the supply line 150 is always left. As a result, heat is generated in the motor module 110 and the pump module 130, Existing fluids also become high temperature fluids. In order to prevent such a phenomenon, when the pump module 130 is operated, the bypass line 140 is operated and the storage tank 190 → the motor module 110 → the pump module 130 → the bypass line The heat generated from the motor module 110 and the pump module 130 is heat-exchanged by the circulating fluid so that the motor module 110 and the pump module 130 130 can be prevented from rising. Accordingly, according to the present invention, it is possible to prevent the temperature rise and to operate the motor module 110 and the pump module 130 for a long time.

The pump module 130 operates by the rotational force provided by the motor module 110 to pressurize the fluid flowing into the suction port 135 to supply the fluid to the discharge port 137 and the bypass line 140. The pump module 130 preferably includes various types of pumps capable of providing a high pressure to the nozzle 165, but includes a plunger type pump. This type of pump is preferable because it can supply the high pressure of about 50 to 100 kg / cm < 2 > to the nozzle 165 more stably and can be formed into a fine particle form at the nozzle 165. An example of using such a nozzle 165 is disclosed in the patent application No. 10-2014-0043380, to which the present inventor belongs.

The pump module 130 may further include a pressure gauge 133 for sensing a pressure to be pressurized and an accumulator 155 for preventing pulsation of the discharged fluid. The pump module 130 is cooled by the cooling unit 143 branched at the bypass line 140 as described later and is heated by the heat generated in the process of operating continuously to form a high pressure in the pump module 130 Can be removed. Accordingly, the pump module 130 has an advantage that it is more stable and does not generate a trouble due to heat or the like even during long-term operation.

The reservoir tank 190 stores a fluid and includes a level switch 193 for sensing the level of the stored fluid and a level switch 193 for interlocking with the level switch 193 to replenish the fluid to maintain the level of the reservoir tank 190 at a constant level. And an overflow line 195 for discharging the fluid overflowing from the storage tank 190 when the fluid is excessively present in the reservoir tank 190. The overflow line 195 has a suction port 135, respectively. In the storage tank 190, the fluid recovered from the various lines 140, 143, 180, and 170 described later can be returned and stored.

The bypass line 140 is provided to continuously flow the fluid during the operation of the motor module 110 and the pump module 130. The bypass line 140 preferably includes a cooling unit 143 for branching off heat generated from the motor module 110 or the pump module 130. The cooling unit 143 is configured to communicate with a space formed in a housing (not shown) of the motor 113 or the pump module 130, or a fluid flowing along a separate flow path. It is preferable that the cooling unit 143 is returned to the storage tank 190 after passing through the motor module 110 or the pump module 130.

The bypass line 140 may include a bypass control valve 145 that is always open during operation but can control the degree of opening of the bypass line 140 to control the amount of fluid flowing through the flow path.

The supply line 150 guides the pressurized fluid and is in communication with the discharge port 137 and has a structure in which a plurality of atomizing lines 160a, 160b, 160c, ..., 160n, where n is an integer, are branched. In the supply line 150, it is preferable that a check valve 157 is provided to control the flow of the fluid only in one direction.

The spray line 160 has a plurality of nozzles 165 and can be atomized into fine particles at the nozzle 165 by high pressure and has a spray opening and closing valve 163 . In this spraying line (160), the fluid may be supplied, cut off, or intermittently supplied and cut off, depending on the needs of the work space requiring atomization of fine particles.

The load control line 170 includes a load control valve 173 having a degree of opening that varies depending on the load of the fluid supplied to the spray line 160 so that the flow rate of the fluid supplied to the spray line 160 150 to guide the fluid to the storage tank 190. For example, if only 30 to 50 spray lines 160 in 100 spray lines 160 are operated, the remaining fluid can be returned to the storage tank 190 through the load control line 170.

In this case, if necessary, the control unit 115 may reduce the rotational speed of the motor 113 in conjunction with the pressure gauge 133 to adjust the amount of fluid to be pressurized while maintaining the pressure constant.

Meanwhile, as described above, when the nozzle 165 is intermittently sprayed, the spraying intermittent line 180 (not shown) communicated with the supply line 150 to guide the pressurized fluid, which is not sprayed due to frequent interruption, ). The spray interrupting line 180 is preferably provided with a spray interrupting opening / closing valve 183 for interrupting the fluid.

The operation of the high-pressure pump apparatus 100 according to such a construction will be described with reference to FIGS. 2 to 4. FIG.

First, when fine particles are formed in almost all the nozzles 165 of the spraying line 160, they are operated as shown in FIG.

When the motor module 110 is operated, the pump module 130 coupled to the motor module 110 is operated, and the pressurized fluid is discharged through the discharge port 137. Most of the fluid discharged at a high pressure can be formed into fine particles while moving along the supply line 150 - the spray line 160 - the nozzle 165 and discharging through the nozzle 165 in the desired working space.

On the other hand, some of the discharged fluid is recovered to the storage tank 190 along the bypass line 140. In this process, the fluid flowing along the cooling section 143 is recovered to the storage tank 190 after cooling the heat generated from the motor module 110 or the pump module 130.

By this operation, fine particles can be formed in the nozzle 165 in a working space requiring continuous constant temperature and humidity, and even when the high-pressure pump apparatus 100 is continuously operated continuously for 24 hours, The heat generation of the module 130 can be prevented, and stable and reliable operation can be performed.

When the load of the pump module 130 or the motor module 110 is reduced due to a small amount of fluid forming fine particles from the high-pressure pump apparatus 100 to the work space, the rotation of the motor 113 The control unit 115 can adjust the speed while maintaining a constant pressure.

On the other hand, the load regulating valve 173 may be actuated in the load regulating line 170 to withdraw the excess fluid from the pump module 130 to the storage tank 190, as shown in FIG. 3b. The degree of opening of the load regulating valve 173 may be controlled by controlling the pressure regulating valve 173 in conjunction with the pressure gauge 133 or the like, 115).

By this operation, the high-pressure fluid is not supplied to the spray line 160, which does not need to form the spray, so that there is no fluid flowing down from the nozzle 165, so that the dirtiness of the work space can be eliminated and the hygiene can be improved.

Also, when the majority of the nozzles 165 are operated to form intermittent fine particles in a rather short time, the spray interruption line 180 as shown in Fig. 3A is useful. The spray interrupting line 180 is provided with a spray interrupting opening / closing valve 183 which is guided by the supply line 150 and opens and closes the fluid guided to the storage tank 190 so that the fluid supplied to the storage tank 190 is intermittently Can supply.

On the other hand, when the operation of the motor module 110 and the pump module 130 is stopped because a high-pressure fluid supplied to the nozzle 165 is unnecessary, the bypass line 140 and the load control The line 170 is completely opened and all the spray opening / closing valves 163a, 163b, 163c, ..., 163n of the respective spray lines 160a, 160b, 160c, ..., 160n are closed. The nozzles 165a-1, 165a-2, 165a-3, ..., 165a-n, 165b-1, 165b-2, 165b- 165n-2, 165c-3, ..., 165c-n, ..., 165n-1, 165n-2, 165n-3, ..., 165n-n, .

Therefore, according to the present invention, it is possible to continuously and continuously supply the fluid to a plurality of high-pressure nozzles sprayed with fine particles, and to continuously and continuously operate the high-pressure motor module or the pump module, It is possible to provide a high-pressure pump apparatus for a spray nozzle.

In addition, it is possible to operate correspondingly to load changes on a plurality of high-pressure nozzle side sprayed with fine particles, thereby providing economical efficiency, reliability, and reliability. In addition, since a fluid sprayed to fine particles does not spray on a plurality of high- It is possible to provide a large number of high-pressure pump apparatuses for spray nozzles which can prevent the fluid from flowing down and improve the hygiene.
