本発明は、水中に設置される圧縮機の、冷却、密封、潤
滑液として水を用いる、水注入式圧１ｉｉａに関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water-injected pressure 1iia, which uses water as a cooling, sealing and lubricating fluid for a compressor installed underwater.
水注入式の圧縮機は油を含まない吐出空気を得られるの
で多用されている。Water-injected compressors are widely used because they provide oil-free discharge air.
その場合、通常の湿度の大気を給気源とすると、吐出圧
力が高くかつ吐出温度が低ければ水蒸気が凝縮するので
凝縮水のみで十分な星の注入水が得られるが、水中に空
気を圧送する目的で一般に用いられる数ｋｇ ｆ ／
ｃａｌ以下の吐出圧力では水蒸気は凝縮しないので圧縮
機に支障を生じない程度に異物を含まない、上水や下水
処理水等、外部に給水源を求めなくてはならない。また
、注入した水は圧縮機を冷却して自身は蒸発するので、
一旦供給しただけでは済まず、補給する必要もある。In that case, if the air with normal humidity is used as the air supply source, if the discharge pressure is high and the discharge temperature is low, the water vapor will condense and the condensed water alone will be enough to obtain star injection water, but air is forced into the water. A number of kg f / commonly used for the purpose of
Since water vapor does not condense at a discharge pressure of less than cal, it is necessary to find an external water supply source, such as tap water or treated sewage water, that does not contain foreign matter to the extent that it does not cause problems to the compressor. Also, the injected water cools the compressor and evaporates itself.
It is not enough to just supply it once; there is also a need to replenish it.
従って、従来では注入水のタンクを圧縮機に接続し、タ
ンクの水位に応じてタンクから給水源に通じる弁を開閉
して注入水を補給することが行われている。Therefore, conventionally, an injection water tank is connected to a compressor, and injection water is supplied by opening and closing a valve leading from the tank to a water supply source depending on the water level of the tank.
従って、従来のものでは圧縮機に外部からの給水配管を
設けねばならず、手間やコストを増大させ、問題点とな
っていた。Therefore, in the conventional compressor, a water supply piping from outside must be provided to the compressor, which increases labor and cost, which is a problem.
本発明は、上述の従来の問題点を解決しようとするもの
で、上水や下水処理水などの別の給水源を必要とせず、
従ってそのための給水配管を不要とできる水注入式圧縮
機を前車な構成として提供することを目的とするもので
ある。The present invention aims to solve the above-mentioned conventional problems, and does not require a separate water supply source such as tap water or treated sewage water.
Therefore, it is an object of the present invention to provide a water injection type compressor that can be installed in front of a vehicle and eliminates the need for water supply piping.
本発明は、上述の問題点を解決するために圧縮機が設置

とするものである。In order to solve the above-mentioned problems, the present invention has been made to utilize the water in the water in which the compressor is installed as injection water. , a water injection compressor is provided, characterized in that a filter is provided at the water intake port of the injected water, and a switching path is provided for selectively connecting the water intake port to the suction side and the discharge side of the compressor. That is.
本発明は上述の構成を具備することにより、圧縮機が配

ルタを逆洗することができる。By having the above-described configuration, the present invention can utilize water in which the compressor is installed as injection water. If the injected water is insufficient, connect the water intake to the compressor suction side and take in clean water from the water intake equipped with a filter.
When no water is being taken in or when the filter is clogged, the water intake port can be connected to the compressor discharge side to blow out air or water and backwash the filter.
この場合、取水口を圧縮機が設置される水中の圧力より
も低圧の圧縮機吸込側に接続すれば差圧で水は流入し、
高圧の圧縮機吐出側とを接続すれば差圧で空気や水は噴
出するので、そのための駆・動源を設ける必要もない。In this case, if the water intake is connected to the compressor suction side, which has a lower pressure than the water pressure in which the compressor is installed, water will flow in due to the differential pressure.
If it is connected to the discharge side of a high-pressure compressor, air and water will be ejected due to the pressure difference, so there is no need to provide a drive source for this purpose.
なお、本発明における圧縮機にはブロワも含むものであ
る。Note that the compressor in the present invention also includes a blower.

逆洗しながら取水口５から吐出する。Thus, air is drawn into the blower l through the intake pipe 3 and discharged into the tank 7 through the discharge duct 6. Utilizing this discharge pressure, the water in the tank 7 is injected into the compression space of the blower 1 through the water injection pipe 11, cooling and sealing the blower 1.
It is used for lubrication, is discharged into the tank 7 together with the discharged air, is separated from the air by gravity and the separator 8, is stored in the tank 7, and is repeatedly circulated. and,
When the three-way valve 13 communicates the water intake 5 and the air pipe 9, the air discharged into the tank 7 separates water and then passes through the air pipe 9 and is discharged into the water from the air diffuser plate lO, and a part of the discharged air is The water is discharged from the water intake port 5 through the discharge branch pipe 14 while backwashing the filter that has collected foreign matter during water intake.

気を噴出させる。When the amount of water in the tank 7 drops below the minimum predetermined amount due to evaporation, the three-way valve 13 is activated by the level switch 16.
Switch the water intake port 5 to the switching path connecting the blower l suction side. Then, clean water flows from the water intake 5 through the filter into the blower suction side due to water pressure, and the inflow water passes through the blower 1 and is supplied to the water injection cycle, but when the water is stored in the tank 7 to a predetermined amount. The level switch 16 switches the three-way valve 13 to a switching path that connects the water intake port 5 and the discharge side of the blower l, stopping water intake and blowing out air from the water intake port 5.

。Although the water intake port 5 is made to selectively communicate with the suction side and the discharge side of the blower 1 so that air is always blown out from the outside of the plate during water intake, it is also possible to have a configuration in which communication with both is stopped.
吐出支管１４は、散気板ｌＯからの吐出■に重大な影響

ィス等を設けることもできる。The discharge branch pipe 14 is provided with a nozzle, an orifice, etc., so that it does not have a significant effect on the discharge from the air diffuser plate IO, and is sufficient to backwash the filter of the water intake port 5 and prevent foreign matter from adhering. You can also do that.
二次フィルタ２０は異物の付着が少ないので逆洗可能な
構成としていないが、逆洗可能にしてもよい。The secondary filter 20 is not designed to be backwashable since there is little adhesion of foreign matter, but it may be made backwashable.
