Abstract

PURPOSE:To purify water in the tank by furnishing a control device, which is actuated by a sensor for the condition of water, having thereby proper adjustment of the water, and by replacing water in the receiver tank automatically. CONSTITUTION:When the water level attains the upper limit point (water increases when the water contained in the inhaled atmosphere liquefies), an electric signal is given from a level sensor 12, which is to sense the water level in a receiver tank 7, to actuate a control device 13. Thus a solenoid valve 14 is opened to exhaust the water 15 from the receiver tank 7 as well as a water supply device 4 is released to supply new water to a compressor 1. When exhaust of the water 15 depress the water level in receiver tank 7 to the lower limit point, the solenoid valve 14 is shut and the water supply device 4 also. Thus the 15 water in the receiver tank 7 can be purified through automatic replacement.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for adjusting water in a compressor using water.

Generally, compressors use oil for lubrication, cooling, and sealing, but there are compressors that use water instead of oil. In this case, there is no oil mixed in the supplied air, so it is harmless, and it has significant advantages such as being cheaper than oil. The water supplied into the compressor cools the compressor and acts as a lubricating medium, and then is sent together with the compressed air to a receiver tank, where it is separated from the air and stored in the receiver tank. The water is then cooled again as it passes through the waterway and then supplied to the compressor for circulation. However, during repeated use, water may become contaminated with impurities, or its quality may deteriorate, and bacteria such as bacteria may occur.

When such a situation occurs, it not only reduces the functionality of the compressor, but also causes inconveniences such as the generation of strange odors. Therefore, check the condition of the water in the compressor from time to time! However, the reality is that no serious consideration has been given to this point, and no optimal method has been proposed.

The present invention was made in view of such conventional situation,
The gist of this method is to provide a sensor necessary to detect the state of water 9 and to provide a control device operated by this sensor, thereby making it possible to appropriately adjust the water.

Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiments. In FIG. The intake air is supplied to the compressor IK. On the other hand, water is supplied to the compressor 1 by a water supply device 4 from a supply source (not shown) such as a water supply. The air (containing water) compressed by the compressor 1 is sent through a pipe 6 equipped with a check valve 5 into a receiver tank 7, and is then passed through a filter 8 etc. to remove water. The air is sent out through the check valve 9, and the water is stored in the receiver tank 7 and is again supplied to the compressor 1 through the pipe 10 and the cooler 11. 12 is a level sensor that detects the water level in the receiver tank 7, and has an upper limit detection point and a lower limit detection point, and the water level reaches the upper limit detection point (when the moisture contained in the inhaled outside air is liquefied). The control device 13 is operated by the electrical signal, and the solenoid valve 14 is opened to increase the amount of water in the receiver tank 7.
At the same time as the water is discharged, the water supply device 4 is opened so that new water can be supplied into the compressor 1. When the water level in the 7-bar tank 7 drops to the lower limit detection point by releasing the water 15, the solenoid valve 14 closes and the water supply device 4 also closes. Therefore, the water 15 in the receiver tank 7 can be replaced with automatic fishing, and cleaning becomes possible. In this case, since the water is replaced with fresh water, it is different from simply removing impurities such as dirt mixed in the water with a filter, etc., and even bacteria that are generated in the water that cannot be removed with a filter can be removed. - This is extremely convenient. Furthermore, unlike lubricating oil, water is inexpensive, so the loss due to replacement is minimal, and furthermore, the discharged water can be treated with an appropriate purification device.

FIG. 2 shows another embodiment of the present invention, in which an operating time counter 16 is provided to measure the operating time of the compressor 1, and when the time of this counter 16 reaches a predetermined time,
The control device 17 causes the solenoid valve 14 and the water supply device 4 to be opened for a certain period of time by a timer and then closed.
This allows 15 tons of water in the tank 7 to be released and new water to be supplied. Therefore, also in this embodiment, the water in the receiver tank 7 can be automatically exchanged.

Fig. 3 shows a third embodiment of the present invention, in which a temperature sensor 18 is provided in the receiver tank 7, and when the temperature value of this sensor becomes less than a predetermined temperature (40° to 5ooc), a solenoid valve 19 is activated. Open and release water 1 in tank 7
5 is heated by the heater I and returned to the resin tank 7. The lock 21 is a pump. In this way, it is possible to kill the Nokuchilia in the water and purify the water.

FIG. 4 further shows a fourth embodiment of the present invention, in which a stop signal is issued to the motor 2 by the starter η of the drive motor 2 of the compressor 1, and at the same time, the same signal is sent to the solenoid valve Inc.
The solenoid valve 14 is opened and the water 15 in the receiver tank 7 is discharged. On the other hand, when a starting signal is issued by the starting device B, the solenoid valve 14 closes, the water supply device 4 opens and new water is introduced, and when the water level in the receiver tank 7 reaches a certain level, the level sensor 12' The water supply device 4 is closed by the signal.

As explained above, according to the present invention, cleaning can be achieved by automatically replacing the water in the cash register/paddle tank or by killing bacteria, and supplying harmless and odorless air. can be done, and the effect is quite remarkable. Furthermore, by purifying the water, it is possible to prevent contamination and functional deterioration of the compressor, Resino 9-tank, and other attached equipment, and since water is cheap, it is also very economical! It is. In addition to using each of the embodiments described above alone, it is also possible to implement some of them in combination.
