Air reservoir with automatic water drainage function

Abstract

The invention discloses an air reservoir with an automatic water drainage function, and belongs to the technical field of engineering machinery. The air reservoir with the automatic water drainage function comprises an air reservoir which is provided with an electric blow-down valve; the inner end of the electric blow-down valve is connected with a flexible rubber hose, and the free end of the flexible rubber hose is connected with a gravity ball; a pressure switch used for detecting the air pressure in the air storage cylinder is installed on the air reservoir, and a contact switch is installed in the air reservoir. The time-delay relay and the contact switch are connected in series to form a control loop; the time-delay relay, the pressure switch and the electric blow-down valve are connected in series to form an execution loop. The air reservoir can automatically discharge water so that the labor intensity is reduced, and the timeliness of water discharge can also be ensured; the pressure switch for gas circuit protection is additionally arranged to ensure that the gas pressure of the gas storage cylinder is not lower than a preset value and the brake pressure is ensured; by additionally arranging the gravity ball and the flexible rubber hose, water can still be discharged normally when the vehicle inclines or swings.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an air storage cylinder with the function of automatically releasing water. Background technique [0002] In the field of construction machinery technology, construction machinery such as loaders, road rollers, and trucks mostly use on-board air compressors to compress air as the power source for braking. The brake system uses an air storage cylinder to ensure that the air pressure in the system is maintained within the working range. Taking a loader as an example, after the air is compressed by the engine air compressor, it passes through the multi-function unloading valve and enters the air storage cylinder. At this time, the water vapor in the air is condensed in the air storage cylinder due to compression. Over time, a lot of water can build up in the cylinder. If the water is not drained in time, the moisture in the brake system will accelerate the corrosion ...

Problems solved by technology

This not only increases the work intensity of the operator, but also cannot release water in time, and there are hidden dangers to driving safety;

[0006] 2. It absorbs the oil-water mixture at the bottom of the air storage tank through the bent hard pipe. When the vehicle is on an inclined road or shaking, the hard pipe cannot always contact the oil-water mixture at the bottom. The absorption effect is poor and immediate drainage cannot be achieved. ;

[0007] 3. When draining water through the drain valve, the gas in the air storage tank will also be partially discharged, which will reduce the air pressure in the air storage tank. If the air pressure is lower than the required pressure of the braking system, there will be a risk of insufficient braking
