Abstract

PURPOSE: An air compressor is provided to improve the use efficiency of the device, to be easily moved and to be safely used by performing the complex functions as both a vacuum pump and an air compressor. CONSTITUTION: The air compressor is used by the steps of:positioning a first three dimensional valve(107) at a passing position; making a second three dimensional valve(108) as a suction valve; opening a first stop valve(109); shutting a second stop valve(201); and driving an electric motor(204).; Therefore, a fluid circulating pump(100) is operated.; Herein, the fluid circulating pump sucks the air in atmosphere and vents the air by high pressure through an air filter and a suction hole(203). The lubricating oil contained in the vented high pressure air is recollected in an oil separator(103), and only the high pressure air is stored in a compressing tank(101) after passing through the first three dimensional valve and the first stop valve. The high pressure air stored in the compressing tank is used when compressed air is needed.

Fluid circulator for both vacuum pump and air compressor

Among the fluid equipment for circulating gas and liquid, the air compressor and the vacuum pump, which have the same principle and characteristics but are separately manufactured and are used for one purpose, are composed of a single device fluid circulation pump and piping equipment. It is to provide a "vacuum pump and air compressor combined fluid circulation device" that can be easily operated by operating the valve, the function can be selected according to the needs of the user.

Among many fluid devices such as windmills, water wheels, gas turbines, steam turbines, air motors, and steam motors, air compressors, refrigerant compressors, and vacuum pumps that transport gas are fluid circulation devices, and have the same principle, operation characteristics, and structure. It is divided into pneumatic field, high pressure gas refrigeration engineering field, vacuum field, etc., and each is produced and sold in different special field devices, so users have no choice but to purchase expensive devices as needed. The economic loss caused by this was high, and the use rate of expensive special equipment was low.

Therefore, there is an urgent need to develop a composite engineering technology device that complements independent devices having the same principle and operation characteristics and combines them into mutually compatible composite devices so that various functions can be utilized in one special device.

As a fluid circulation pump that delivers gas, it combines the functions of a vacuum pump and an air compressor to improve the utilization efficiency of the device, to be easy to move, safe and convenient to use, and to reduce the cause of failure. In order to prevent the operation from being exposed to the outside and to make the size small and light, it is applied to a high-pressure gas refrigeration apparatus and is used as a refrigerant compressor, an air motor or a vacuum pump, and a completely sealed rotary or scroll type fluid transfer pump. In order to develop a "vacuum pump and air compressor combined fluid circulation system" that utilizes the characteristics of fluid equipment by installing a piping system connecting a compression / vacuum tank and a valve that can be operated as necessary. .

The present invention is composed of a pressure / vacuum tank, interconnection piping and valves that can store high-pressure air or maintain a vacuum in order to multi-purpose application of the function of the circulation pump for high-pressure gas refrigerant for conveying fluid materials It can be used as a vacuum pump or an air compressor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an overall configuration characteristic and a detailed operation method of an apparatus of the present invention will be described.

FIG. 1 is an installation structure diagram showing the piping system of the components and fluid flow of the present invention, wherein the fluid circulation pump 100 and the compression / vacuum tank 101 driven by the electric motor 204 are mutually connected. Piping device to connect.

First, when you want to use it as an air compressor,

The first three-way valve 107 is set to the passing position, the second three-way valve 108 is suctioned, the first stop valve 109 is opened, the second stop valve 201 is closed, and the electric motor is 204 is driven to operate the fluid circulation pump 100.

The fluid circulation pump 100 sucks air in the atmosphere and discharges the air at high pressure through the air filter and the inlet 203. At this time, the lubricating oil contained in the discharged high pressure gas is recovered by the oil separator 103, Only gas passes through the first three-way valve 107 and the first stop valve 109 is stored in the compression tank 101, and is used when compressed air is required.

Next time I want to use it as a vacuum pump,

Set the first three-way valve 107 to the discharge position, the second three-way valve 108 to the passing position, close the first stop valve 109, open the second stop valve 201, and The motor 204 is driven to operate the fluid circulation pump 100.

The fluid circulation pump 100 sucks air in the vacuum tank 101 and discharges the air from the air outlet 202 through the oil separator 103 and the first three-way valve 107 to the atmosphere while vacuuming the inside of the tank. It is used when vacuum adsorption is required.

2 is an electric circuit wiring diagram configured to safely operate and stop the apparatus shown in FIG. 1, and applies a circuit of a general line starter used when driving basic electric equipment, and high temperature and high pressure may occur. Due to the characteristics of the device, the pressure switch (PS, 104) and the high temperature switch (HTS) are installed in series with the overload relay (OL), so that the safe operation can be performed automatically while maintaining the safe pressure and temperature set by the user. ,

It combines the functions of an air compressor and a vacuum pump in a single unit, but is smaller and lighter than conventional independent vacuum pumps and air compressors, and improves economics, practicality and safety. Device ".

As the number of automobiles increases, the use of compressed air is increasing. It is used in air tools, including pistons of automated pneumatic devices, and compressed air is used for tire wind, high pressure washer or spray paint work, and various repair work. The use of vacuum pumps for adsorption, such as refrigerators using refrigerators, and for recovering refrigerant during repair of refrigeration or air-conditioning heat pump devices, or for simple repairs to parts outside the car,

Until now, air compressors and vacuum pumps were manufactured and sold as special equipment from different companies, so users had to purchase two according to their use. The device of the present invention can be configured by adding a fluid circulation system only in a single compact unit, and can be utilized by changing the function with a vacuum pump or an air compressor according to the needs of the user, so the demands of individual operators and owner drivers are extremely high. In many cases, the producer of the product is able to produce and supply a device with a complex function at the price of a single device, and is a "fluid circulator with a vacuum pump and an air compressor" of fluid engineering technology that satisfies economy, practicality and safety. .
