Problems solved by technology

If there are a lot of air bubbles in the hydraulic oil, when the hydraulic oil passes through the high-pressure pump, the air bubbles will burst due to pressure changes, causing serious noise pollution. At the same time, the impact force in the high-pressure state can easily cause damage to the high-pressure pump

Embodiment Construction

[0014] as attached figure 2 As shown, the air bubble reduction device of the present invention is added between the fuel tank 12 of the CNG hydraulic filling substation and the oil return port 6. The air bubble reduction device includes a surge device 8 and a slide device 4, and the hydraulic oil 14 is from the oil return port. 6 flows into the surge device 8, then flows into the slide device 4, and flows into the fuel tank through the guide plate 13.

[0015] The oil inlet of the surge device 8 is the oil return port 6 of the fuel tank, and the surrounding four surge device baffles 9 and the bottom plate weld the device into a box shape, and the attached image 3 It is a top view of the surge device, and a plurality of partitions 7 are fixedly welded inside the surge device 8. The partitions 7 are divided into an upper partition 7-1 and a lower partition 7-2, and the upper partition 7-1 and the bottom plate Leave a distance to keep the lower part of the upper partition 7-1 ...

Abstract

The invention discloses a bubble reducing device for hydraulic oil for a CNG hydraulic substation. The bubble reducing device is disposed between an oil return opening and an oil tank, and includes asurge type device and a slide type device. The surge type device is internally and fixedly provided with partition plates, and the partition plates force the hydraulic oil to pass in a wave shape mode. A stainless steel wire mesh is laid on the slide type device. The surge type device forces the hydraulic oil to flow in a turbulence mode, the collision of bubbles is increased, and at the same time, the floating time of the bubbles is ensured, so that it is ensured that the hydraulic oil separates the large bubbles; and the slide type device divides the small bubbles into micro-bubbles again, so that the problems of the noise pollution and damage of a high pressure pump caused by bubble breakage in the hydraulic oil are solved, the safe running time of the CNG hydraulic substation is increased, the operating efficiency is improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, in particular to a device for reducing air bubbles in hydraulic oil in a CNG hydraulic substation. Background technique [0002] Natural gas, as a high-quality clean energy, is more and more widely used, and the construction and development of natural gas CNG hydraulic filling sub-stations have broad prospects. The storage of natural gas in the natural gas CNG hydraulic filling sub-station is mainly a gas cylinder trailer, with figure 1 It is a schematic diagram of the principle of filling gas for the user by the hydraulic gas filling sub-station. The hydraulic oil in the oil tank 3 of the hydraulic station injects the oil into the gas cylinder 2 under the condition of not less than the pressure of the gas cylinder, and sends the natural gas CNG in the gas cylinder 2 into the gas filling Machine 1, filled by gas dispenser 1 to gas equipment such as gas taxis. During the process of filling th...
