This seemingly good measure has buried a very big hidden danger for the safety of the whole hydraulic system.
The exhaust pipe of the automatic feeding mixer truck will discharge the hot gas in the oil tank and condense into water in the bottle. Usually, the flushing water and rainwater will also flow into the bottle along the air pipe. When the oil tank is cooled, the water will be sucked back into the oil tank through the exhaust pipe. The hydraulic oil with water will soon deteriorate into milky white, which is usually called oil emulsion.
The lubricating performance and compression performance of emulsified hydraulic oil will be seriously reduced, resulting in a series of problems. At least, the internal leakage of pump Mada is weak, and each rubber ring and oil seal are worn and leaked. The oil seal at the pump shaft end leaks oil, the rubber ring of the control valve is worn and leaks oil, which will seriously wear and even scrap the plunger slippers and oil distribution discs of the hydraulic pump and motor.
The pump of the automatic feeding mixer truck is seriously worn. The better solution is to extend the exhaust pipe vertically under the truck and let the discharged oil drip naturally to the ground. Do not knot or wind the exhaust pipe. Friends who still hang water bottles, get rid of the bottles quickly!!
Fortunately, the radiator of the automatic feeding mixer truck has been improved. An oil recovery box has been installed on the side of the oil tank, which can effectively solve the problem of pollution. The box capacity is limited. Everyone should remember to check and wipe it frequently and drain the accumulated oil in time, especially in the days after the new car has just been used and changed.
