Description
Technical Field
The invention belongs to the technical field of fluid pressure actuating mechanisms, and particularly relates to a hydraulic station with a stable structure.
Background
The hydraulic station main body is a hydraulic source device which is driven by a motor to provide flow power for a hydraulic pump and is matched with an oil tank to form supply and return effects of hydraulic oil; in the supply-return relation, an overflow valve and a throttle valve are integrated in a supply-return pipeline to form constant-pressure overflow and integrated quick-acting use, an oil inlet end at one side of a direction valve is connected with an oil discharge end of a hydraulic pump through a pipeline, and other access ends are connected with an oil inlet end and an oil return end of an executive element taking hydraulic pressure as power through pipelines; in the oil return pipeline, a hydraulic oil cooler is also connected, one oil inlet end of the hydraulic oil cooler is connected to at least one access end of the directional valve through a pipeline, and the oil outlet end of the hydraulic oil cooler is connected to an oil return pipeline connected with an oil tank through a pipeline, so that the recovered hydraulic oil can be effectively cooled; in order to better improve the overall power output quality, the oil outlet end of the hydraulic oil cooler is connected with the branch inlet end of the hydraulic pump through a pipeline to form a hydraulic differential loop, so that when the requirement of the extending speed of an actuating element taking hydraulic pressure as power is high under the condition of speed regulation of an overflow valve and a throttle valve, the mechanism extending unit can be extended more quickly;
when the energy storage requirement exists on the oil tank, an energy accumulator is also arranged on the oil tank; in addition, one side of the oil tank is also provided with a pressure release valve for normal pressure release of the oil tank due to different reasons, the lower part of one side of the oil tank is provided with a slag discharge valve for flushing and discharging residues at the bottom of the oil tank when hydraulic oil is replaced in the oil tank, and the pressure release valve and the slag discharge valve are required to be closed in a normal state; in addition, a pressure gauge is arranged on the oil tank and used for displaying the pressure value in the oil tank in real time.
However, in the long-term use process of the hydraulic station in a humid and water-containing environment, the hydraulic station is influenced by the self-tightness of the executive component taking hydraulic pressure as power and the self-tightness of the hydraulic station, water with different degrees can be fleed into the oil tank, after the hydraulic oil is mixed with the water, the hydraulic oil is emulsified, the compressibility of the hydraulic oil can be increased, the action of the executive component is error, creeping and vibration are generated, and the working stability of a hydraulic system is influenced; secondly, water is easy to combine with air to generate water bubbles, the water bubbles are smashed under the action of high pressure to generate strong vibration and noise, so that the action responsiveness of the element is greatly reduced, the action is delayed, and the control accuracy is affected; the oil film of the actuating element is damaged, so that the sliding surface is scratched, abrasion is increased, the hydraulic element is corroded by water, and punctiform corrosion abrasion is generated on the metal surface. Most importantly, when the hydraulic oil contains more water, the volumetric efficiency of the hydraulic system is reduced, the energy loss is increased, and the transmission efficiency is reduced. All of the above are factors of unstable operation that occur after moisture enters the tank.
These cases occur, the dominant phenomena are: when the external executive component operates, the gauge needle of the pressure gauge on the oil tank is in an unstable reciprocating swinging state, which is caused by the instability of the operation of the hydraulic oil mixed with water connected with the hydraulic system.
Therefore, in order to prevent moisture from entering the hydraulic oil to influence the normal operation of the hydraulic system, when the situation occurs, whether the oil tank is sealed well or not and whether the oil suction pipeline and the connecting pipeline are not damaged should be checked; periodically emptying and filtering oil from the oil tank; in addition, the hydraulic oil is periodically checked, and if the hydraulic oil is abnormal, the hydraulic oil is timely replaced.
However, in addition to the basic maintenance operation described above, since the water in the oil tank is often present in a very small amount, it is almost unavoidable that the water is mixed in the oil tank; in order to more efficiently remove the moisture in the oil tank in the full oil return state when the oil supply is not performed, it is necessary to provide a hydraulic station with a stable structure capable of more effectively removing the moisture in the oil tank in combination with the change condition of the pressure value of the oil tank.
