Description

증압펌프와 이를 이용한 세륜기{With the raising pressure pump the wheel washing system which uses raising pressure pump}Booster pump and washing machine using it {with the raising pressure pump the wheel washing system which uses raising pressure pump}

본 발명은 소형의 저압펌프로 구동하는 증압펌프에 관한 것으로, 더욱 상세하게는 저전압으로 구동되는 소형펌프로 증압실린더와 가압실린더를 구동하여 고압의 유체를 공급할 수 있도록 하여 사용전력을 절감하고, 작은 공간에 설치할 수 있도록 소형화한 증압펌프에 관한 것이다.The present invention relates to a booster pump driven by a small low pressure pump, and more particularly, a small pump driven by a low voltage to drive a booster cylinder and a pressurized cylinder to supply a high pressure fluid to reduce power consumption, and The present invention relates to a booster pump miniaturized to be installed in a space.

일반적으로 유체를 고압으로 가압하기 위한 펌프는, 전동기를 이용한 전동기증방식과, 유압을 이용하여 실린더 내부의 유체를 가압하여 증압하는 유압증압방식 및 에어를 가압하여 증압하는 에어증압방식 등이 제안되어 사용되고 있다.In general, pumps for pressurizing a fluid at high pressure include an electric motor increasing method using an electric motor, a hydraulic pressure boosting method for pressurizing and increasing a fluid inside a cylinder using hydraulic pressure, and an air pressure boosting method for pressurizing and increasing air. It is used.

상기 전동기 증압방식은, 플런저펌프(Plunger pump)가 대표적으로 사용되고 있는 바, 전동기의 회전수 제어 및 출력증가를 위해 클랭크축에 대형의 감속기어를 설치한 것이나, 이는 400rpm이하로 감속이 곤란하고, 압력상으로 1500kgf/㎠ 정도가 상한이다.In the motor boosting method, a plunger pump is typically used, and a large reduction gear is installed on the crankshaft to control the rotation speed and increase the output of the motor, but it is difficult to reduce the speed to 400 rpm or less. It is an upper limit about 1500 kgf / cm <2> in a pressure phase.

또한 상기한 전동기 증압방식은, 하나의 펌프로 다른 액체의 처리는 곤란하고, 고압펌프를 구동하는 전원이 지속적으로 공급되면 발생되는 압력은 무한대로 상승하므로 안전밸브,와 그의 제어장치는 필수적이고, 신뢰성에도 심각한 문제가 발생된다.In addition, the motor boosting method, it is difficult to process the other liquid with one pump, the pressure generated by the power supply to drive the high-pressure pump continuously rises to infinity, so the safety valve, and its control device is essential, There are also serious problems with reliability.

상기 유압증압방식은, 전동기로 유압펌프를 작동시키고 이 유압을 이용하여 파스칼의원리를 기초로 한 증압펌프를 구동시켜 필요한 고압을 얻는 것인데, 유압펌프, 유압밸브, 기름탱크 등을 필요로 하기 때문에 유압장치의 크기가 대형화하는 단점이 있다. The hydraulic pressure boosting method is to operate the hydraulic pump with an electric motor and to use the hydraulic pressure to drive the boosting pump based on the principle of Pascal to obtain the required high pressure, since it requires a hydraulic pump, a hydraulic valve, an oil tank, and the like. There is a disadvantage that the size of the hydraulic device is large.

또한, 전기적인 에너지를 전동기와 유압펌프를에 의해서 유압으로 변환하고, 이 에너지를 이용하기 때문에 에너지 효율이 저하된다.In addition, since the electrical energy is converted into hydraulic pressure by the electric motor and the hydraulic pump, and the energy is used, the energy efficiency is lowered.

상기 에어증압방식은, 압축공기에 의한 파스칼의 원리로 한 증압펌프를 구동시킴으로써 필요한 압력을 얻는 것이지만, 일반적인 고압가스의 규제에 의해 10kgf/㎠ 미만의 공기압을 이용하고 있다.The above-mentioned air pressure boosting method is to obtain the required pressure by driving a pressure boosting pump based on Pascal based on compressed air, but air pressure of less than 10 kgf / cm 2 is used by the regulation of general high pressure gas.

따라서, 필요한 고압을 얻으려면 예를 들어 2000kgf/㎠의 압력을 얻으려면 부스터의 배율은 200배로 되어 큰 부스터의 배율이 필요하므로 방대한 공기량이 필요하게 되며, 이는 대형의 공기압축기를 만들게 되는 원인이다.Therefore, in order to obtain the required high pressure, for example, to obtain a pressure of 2000 kgf / cm 2, the magnification of the booster is 200 times and a large booster is required, which requires a large amount of air, which is the cause of making a large air compressor.

이와 같이 종래의 유체를 고압으로 가압하는 목적을 위해 사용되고 있는 종래의 고압펌프는 그 크기가 대형화되는 문제점과, 에너지 효율이 적다는 단점 및 압력발생의 정확도 등이 떨어지는 문제점들이 있었다.As described above, the conventional high pressure pump, which is used for the purpose of pressurizing the fluid at high pressure, has problems of increasing its size, disadvantages of low energy efficiency, and low accuracy of pressure generation.

본 발명은 상기한 종래의 유체를 고압으로 가압하는 가압펌프를 제공하되, 에너지 효율을 극대화시킬 수 있으며, 작은 크기의 가압펌프를 제공하여 작은 장소에서도 사용이 가능토록 하며, 일정한 압력으로 증압된 유체를 소정의 시간동안 지속적으로 공급할 수 있는 증압펌프를 제공하고자 함을 그 목적으로 한다.The present invention provides a pressurized pump for pressurizing the above-mentioned conventional fluid at high pressure, and can maximize energy efficiency, and provides a pressurized pump of a small size so that it can be used in a small place, and the fluid is boosted to a constant pressure. It is an object of the present invention to provide a booster pump that can continuously supply a predetermined time.

즉, 소형의 저압펌프를 가압탱크 1기압에서 5기압까지 증압시키는 증압시간의 단축을 목적으로 한다.That is, the purpose of the present invention is to shorten the boosting time for boosting the small low pressure pump from 1 atm to 5 atm of the pressurized tank.

상기한 목적을 해결하기 위한 수단으로, 적은 에너지로 구동하는 압력펌프와, 이 압력펌프의 압력을 전달받아 유체를 증압하는 증압장치를 가동하는 가압장치를 일렬로 구성하여, 상기 가압장치에서 발생되는 압력을 증압장치에 전달하여 유체를 고압으로 증압하도록 구성한다.As a means for solving the above object, a pressure pump for driving with low energy and a pressure device for operating a pressure increasing device for boosting a fluid by receiving the pressure of the pressure pump in a row, The pressure is transmitted to the pressure intensifier to configure the fluid to pressure increase.

이러한 구성은, 가압장치와 증압장치를 연속하여 직렬로 구성하고, 가압장치에서 전달되는 압력에 의해 증압장치를 가동시키되, 상기 가압장치에서 발생되는 유체의 가압력을 소구경의 실린더로 전달하여 후방에 위치하는 증압장치의 증압력을 향상시키고, 증압하는 시간을 지연시켜 일정한 시간 동안 증압된 유체를 공급할 수 있도록 한다.This configuration comprises a pressurizing device and a booster in series, and operates the booster by the pressure transmitted from the pressurizing device, and transmits the pressing force of the fluid generated from the pressurizing device to a small diameter cylinder to the rear. To increase the pressure of the pressure booster located, delay the time to increase the pressure so that the supply of the boosted fluid for a certain time.

상기한 목적을 달성하기 위한 본 발명의 증압펌프는, 구동을 위한 전원이 24W의 적은 전력으로도 구동시킬 수 있어 에너지 효율을 극대화시킬 수 있다.The booster pump of the present invention for achieving the above object, the power for driving can be driven even with a small power of 24W can maximize the energy efficiency.

또한, 그 크기가 적은 소형으로 제작가능하므로 증압된 압력을 필요로 하는 모든장치에 적용가능하여 전체적인 증압된 유체를 이용하는 기계의 크기를 소형화 할수있는 특징이 있다.In addition, since it can be manufactured in a small size, it can be applied to any device that requires increased pressure, so that the size of the machine using the whole pressured fluid can be reduced.

이하에서 본 발명의 구성과 작용을 상세히 설명한다.Hereinafter, the configuration and operation of the present invention will be described in detail.

제1가압실린더와 증압실린더를 소구경의 제2가압실린더로 직렬 연결하며, 상기 제1가압실린더에 절환밸브와 펌프를 연결하되, 상기 제1가압실린더를 가압피스톤으로 분할하여 제1가압실, 제2가압실 및 제3가압실로 분할하는 제1가압실린더의 가압실 분할수단과; 상기 제2가압실과 상기 소구경의 가압실린더내의 제4압력실을 연결하여 제2가압피스톤을 작동시키고, 이에 의해 증압실린더내의 증압피스톤을 이동시켜 증압실로 유입된 유체를 증압하도록 한 유체의 증압수단;으로 구성한 것이다.A first pressurizing cylinder and a boosting cylinder are connected in series to a second pressurizing cylinder having a small diameter, and a switching valve and a pump are connected to the first pressurizing cylinder, and the first pressurizing cylinder is divided into pressurized pistons to press the first pressurizing chamber, Pressurizing chamber dividing means of the first pressurizing cylinder divided into a second pressurizing chamber and a third pressurizing chamber; Pressure-increasing fluid for connecting the second pressure chamber and the fourth pressure chamber in the pressure cylinder of the small diameter to operate the second pressure piston, thereby moving the pressure-increasing piston in the pressure-increasing cylinder to pressurize the fluid introduced into the pressure-increasing chamber. It is composed of.

상기 제1가압실린더의 가압실 분할수단은, 대구경의 후방실린더와, 소구경의 전방실린더로 구획하며, 상기 대,소구경의 실린더에 밀착되도록 소수경의 전방피스톤과 대구경의 후방피스톤을 형성하여 결합시키고, 상기 후방피스톤의 우측면과 후방실린더 사이에 제1압력실을 구성하여 펌프와 연결관으로 연결하며, 상기 소구경 의 전방실린더와 소구경의 전방피스톤의 좌측면 사이에 제3입력실을 구성하여 펌프와 연결관으로 연결하고, 상기 후방피스톤과 전방피스톤의 연결부부분과, 전방실린더와 후방실린더의 연결부분에 제2압력실을 형성하여 구성하였다.The pressurizing chamber dividing means of the first pressurized cylinder is divided into a rear cylinder of a large diameter and a front cylinder of a small diameter, and formed by combining a small diameter front piston and a large diameter rear piston so as to be in close contact with the large and small diameter cylinders. And a first pressure chamber is formed between the right side surface of the rear piston and the rear cylinder and connected to the pump and the connection pipe, and a third input chamber is formed between the front cylinder of the small diameter and the left side of the front piston of the small diameter. By connecting the pump and the connection pipe, the rear piston and the connecting portion of the front piston, and formed a second pressure chamber in the connecting portion of the front cylinder and the rear cylinder.

상기 유체의 증압수단은, 제1가압실린더에 형성된 제2압력실과, 소구경의 제2가압실린더에 제2가압피스톤을 설치하여 상기 제2가압실린더 내부에 제4압력실을 형성하며, 이 제4압력실을 상기 제1가압실린더의 제2압력실과 연결파이프로 연결하여 유체를 충진한다. 상기 제2압력실에서 공급되는 유체의 압력에 의해 제2가압피스톤을 작동시키도록 하였다.The pressure boosting means may include a second pressure chamber formed in the first pressure cylinder, and a second pressure piston installed in the small diameter second pressure cylinder to form a fourth pressure chamber inside the second pressure cylinder. The fourth pressure chamber is connected to the second pressure chamber of the first pressure cylinder by a connecting pipe to fill the fluid. The second pressurized piston was operated by the pressure of the fluid supplied from the second pressure chamber.

상기 제2가압피스톤을 연장하여 상기 증압실린더 내에 장착된 증압피스톤과 연결하며, 상기 증압실린더 내부에는, 증압피스톤에 의하여 증압실을 구획 형성하고, 이 증압실 상단에는 유체유입구를 형성하며, 측단에는 증압배출구를 형성하여, 상기 제2가압피스톤의 이동에 따라 증압피스톤이 이동하고, 이 증압피스톤의 이동에 의해 유체유입구를 통하여 증압실로 유입되는 유체를 가압하여 가압배출구를 통하여 배출하는 것이다.The second pressurizing piston is extended to connect with a boosting piston mounted in the boosting cylinder, and a boosting chamber is formed inside the boosting cylinder by a boosting piston, and a fluid inlet is formed at an upper end of the boosting chamber. A pressure boosting outlet is formed, and the pressure boosting piston moves according to the movement of the second pressure piston, and the pressure flowing into the pressure increasing chamber through the fluid inlet is pushed out by the pressure inlet.

상기 유체유입구는 유체저장탱크와 연결하며, 역류를 방지하기 위해 역류방지밸브가 설치된다.The fluid inlet is connected to the fluid storage tank, and a non-return valve is installed to prevent the reverse flow.

상기 제2가압실린더의 내경은, 제1가압실린더의 내경보다 작게 형성된다.The inner diameter of the second pressurized cylinder is formed smaller than the inner diameter of the first pressurized cylinder.

상기 제2가압실린더의 체적과 제1가압실린더내의 제2압력실 체적의 크기 차이는 상기 제2가압실린더에 장착된 제2가압피스톤의 이동거리를 결정한다.The difference in size between the volume of the second pressurized cylinder and the volume of the second pressurized chamber in the first pressurized cylinder determines the moving distance of the second pressurized piston mounted to the second pressurized cylinder.

이와 같이 구성된 본 발명의 증압펌프의 작동상태를 설명한다.The operating state of the booster pump of the present invention configured as described above will be described.

먼저 펌프를 작동시키고, 절환밸브를 조정하여 펌프에서 발생된 압력을 제1가압실린더의 제1압축공기 유입구를 통하여 제1압력실로 공급한다.First, the pump is operated, and the switching valve is adjusted to supply pressure generated in the pump to the first pressure chamber through the first compressed air inlet of the first pressure cylinder.

제1압축공기 유입구를 통하여 유입된 압력은, 제1압력실의 제1가압피스톤을 전진시킨다.The pressure introduced through the first compressed air inlet advances the first pressure piston of the first pressure chamber.

상기 제1가압피스톤이 전진하면, 대구경의 제1압력실과 후방피스톤사이에 형성된 제2압력실에 충진된 유체가 제2가압실린더의 제4압력실로 공급되면서 제2가압피스톤을 이동시킨다.When the first pressure piston moves forward, the fluid filled in the second pressure chamber formed between the large diameter first pressure chamber and the rear piston is supplied to the fourth pressure chamber of the second pressure cylinder to move the second pressure piston.

상기 제2가압피스톤이 전진함에 따라 일체로 형성된 증압실린더내의 증압피스톤이 전지하게 되고, 증압실에 충진되어 있는 유체를 증압하여 증압배출구로 배출하게 되는 것이다.As the second pressure piston moves forward, the pressure piston in the pressure-increasing cylinder integrally formed is charged, and the fluid filled in the pressure-increasing chamber is boosted to be discharged to the pressure-increasing outlet.

이러한 과정으로 증압된 유체를 배출한 후, 상기 펌프에 연결된 절환밸브를 조정하여 제1가압실린더의 제3압력실에 펌프의 압력을 공급한다.After discharging the boosted fluid in this process, the switching valve connected to the pump is adjusted to supply the pressure of the pump to the third pressure chamber of the first pressure cylinder.

제3압력실에 공급된 압력은 제1가압피스톤을 밀어내게되고, 이에 의하여 제2가압실린더의 제4압력실로 이동해 있던 유체를 제2압력실로 환원시키는 것이다.The pressure supplied to the third pressure chamber pushes out the first pressure piston, thereby reducing the fluid that has moved to the fourth pressure chamber of the second pressure cylinder to the second pressure chamber.

즉, 제1가압실린더 내의 제1가압피스톤이 후진하면서 제2가압실린더의 제4압력실과 연결된 연결파이프를 통하여 흡입하여 원위치시키는 것이다.That is, the first pressure piston in the first pressure cylinder is retracted while being sucked back through the connection pipe connected to the fourth pressure chamber of the second pressure cylinder.

본 발명에 있어서, 제1가압실린더의 중앙부에 형성된 제2압력실의 체적과, 제2가압실린더의 제4압력실 체적의 비율은 제2가압피스톤의 행정거리를 결정하게 되므로, 증압펌프의 용도에 따라 변경하여 설계한다.In the present invention, the ratio of the volume of the second pressure chamber formed in the central portion of the first pressurized cylinder and the volume of the fourth pressure chamber of the second pressurized cylinder determines the stroke distance of the second pressurized piston. Design according to change.

상기 제2가압피스톤의 행정거리에 따라 증압실린더에서 증압되어 배출되는 증압유체의 배출속도와 배출량을 결정하게 된다.According to the stroke distance of the second pressure piston, the discharge speed and the discharge rate of the boosted fluid discharged by being boosted in the booster cylinder are determined.

즉, 제2가입피스톤의 행정거리가 길어지면, 증압실에서 증압되는 유체의 증압배출속도가 지연되면서 배출되는 것이다.That is, when the stroke length of the second subscription piston is long, the pressure increase discharge rate of the fluid under pressure is delayed and discharged.
