Description
Technical Field
The invention relates to a hydraulic oil degassing device, in particular to a hydraulic oil degassing device utilizing a transparent vacuum tank and ultrasonic waves.
Background
The existing underwater glider generally adopts hydraulic oil as a buoyancy adjusting system of a working medium. In the working process, hydraulic oil is used as a medium for changing the volume of the glider, and the hydraulic oil is continuously discharged out of the glider and then flows back into the glider from the outside of the glider to change the buoyancy of the glider and provide power for the gliding of the glider. During this period, the hydraulic oil is constantly flowing in the buoyancy system, and the external load pressure is constantly changing, so that the originally dissolved gas in the hydraulic oil is easily separated out. When the gas separated out is too much, the gas may be sucked into the pump, causing cavitation damage to the pump, affecting the performance of the pump, and directly causing the pump to be damaged in severe cases. Therefore, before the hydraulic oil is used formally, the hydraulic oil needs to be degassed to remove gas dissolved in the oil, so that the condition that the buoyancy system of the glider does not generate or only generates a small amount of gas in the operation process is ensured.
Most of the prior degassing methods are that hydraulic oil is put in a vacuum tank, and after the hydraulic oil is put in the vacuum tank for a long enough time, the gas is judged to be completely removed. By adopting the mode, firstly, the vacuum tank body is not transparent, the specific state of the hydraulic oil in the tank cannot be judged, secondly, the vacuum degassing is only relied on, the efficiency is low, the degassing is not thorough, and the vacuum degassing tank can be used after a long enough time, thereby seriously delaying the project schedule.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides a hydraulic oil degassing device utilizing a transparent vacuum tank and ultrasonic waves, which aims to solve the problem that after the existing glider adopting a buoyancy regulating system adopting hydraulic oil as a working medium runs for a long time, the buoyancy system accumulates a large amount of gas to cause damage to hydraulic components or the running of the glider must be stopped for safety.
The purpose of the invention is realized by the following technical scheme:
a hydraulic oil degassing device utilizing a transparent vacuum tank and ultrasonic waves comprises a vacuum tank body, wherein the vacuum tank body is a transparent tank body and is placed on a support, an upper end cover of the vacuum tank and a lower end cover of the vacuum tank are respectively installed at the top and the bottom of the vacuum tank body through a screw and a nut, a quick connector is arranged on the upper end cover of the vacuum tank, and a negative pressure gauge and a hand valve are arranged on the quick connector; the middle part of the lower end cover of the vacuum tank is provided with an ultrasonic transducer which is connected with an ultrasonic control box; an oil inlet and outlet pipe is also arranged on the lower end cover of the vacuum tank, and an electromagnetic valve is arranged on the oil inlet and outlet pipe.
Furthermore, an O-shaped sealing ring is arranged between the ultrasonic transducer and the lower end cover of the vacuum tank.
Furthermore, the tail end of the oil inlet and outlet pipe is also connected with a filtering device and a bidirectional pump.
Furthermore, scales are arranged on the vacuum tank body.
Compared with the prior art, the technical scheme of the invention has the following beneficial effects:
1. the invention adopts a transparent vacuum tank body, the tank body is connected with a negative pressure gauge, whether hydraulic oil in the tank is clean or not and whether bubbles are separated out are clear at a glance, and the pressure in the tank can be clearly read through the pressure gauge.
2. Scales are marked on the tank body, and the volume of the hydraulic oil in the tank body is clear and visible.
3. Install ultrasonic device additional and assist the exhaust, improve the degasification speed greatly, need stand 24h before and can remove gas in the hydraulic oil to the greatest extent, only need 12h after installing ultrasonic device additional.
4. The degassing quality is improved. Under the action of ultrasonic waves, gas dissolved in hydraulic oil is fully separated out, and the degassing effect is far better than that of standing for a long time.
5. The electromagnetic valve is used for controlling hydraulic oil to enter without using a hand valve, so that unnecessary external torque borne by the joint of the lower end cover of the tank body is avoided, the possibility of loosening the joint is reduced, and the leakage risk of the tank body is reduced
