Abstract
The utility model relates to a kind of CNG hydraulic substation and prevents hydraulic oil from beating device.Gas buffer tank communicates into and out of the seal of tube with rock gas respectively, and gas buffer tank internal fixtion liquid level sensor, liquid level sensor is electrically connected with the controller of CNG hydraulic substation.Can effectively prevent hydraulic oil from beating phenomenon.
Description
Technical field
The utility model belongs to a kind of hydraulic protector of hydraulic substation, and particularly a kind of CNG hydraulic substation prevents hydraulic oil from beating device.
Background technique
Rock gas is a kind of high-quality clean energy; the material that can affect human breathing health produced in its combustion process is few; without waste residue, waste water generation after burning, having the advantages such as safety, calorific value are high, clean compared to coal, oil equal energy source, is one of optimal fuel of protection of the environment.The advantages such as natural gas automobile secondary gas filling station has little investment, and ability to work is high, and operating cost is low, automatically controls, very little maintenance, stable, development prospect is wide.Although but there is knock out drum occasional to occur hydraulic oil to squeeze into substation gas cylinder when unloading rock gas, namely phenomenon beaten by hydraulic oil.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of CNG hydraulic substation to prevent hydraulic oil from beating device.Can effectively prevent hydraulic oil from beating phenomenon.
The technical scheme in the invention for solving the technical problem is: gas buffer tank communicates into and out of the seal of tube with rock gas respectively, and gas buffer tank internal fixtion liquid level sensor, liquid level sensor is electrically connected with the controller of CNG hydraulic substation.
The utility model structure is simple, and automaticity is high, can effectively prevent hydraulic oil from beating phenomenon.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, gas buffer tank 2 seals into and out of pipe 1,3 with rock gas respectively and communicates, and gas buffer tank 2 internal fixtion liquid level sensor 4, liquid level sensor 4 is electrically connected with the controller (not shown in FIG.) of CNG hydraulic substation.
Liquid level in liquid level sensor 4 measurement gas knock out drum 2.Under normal working state of system, do not have hydraulic oil in gas buffer tank 2, what be full of is all high-pressure natural gas gas, and then liquid level sensor 4 does not also just show.When hydraulic oil was beaten, when part is injected in gas buffer tank 2, liquid level sensor 4 has also just had corresponding display, at this moment, the controller of CNG hydraulic substation will according to the start and stop of the display control oil pump of liquid level sensor 4, prevent oil pump from again working and hydraulic oil is injected in aerating vehicle.Gas buffer tank 2 is also a barrier of substation and aerating vehicle centre, as long as do not have hydraulic oil in gas buffer tank 2, hydraulic oil would not be injected in aerating vehicle.
Claims (1)
1. a CNG hydraulic substation prevents hydraulic oil from beating device, it is characterized in that: gas buffer tank (2) seals with rock gas communicate into and out of managing (1,3) respectively, gas buffer tank (2) internal fixtion liquid level sensor (4), liquid level sensor (4) is electrically connected with the controller of CNG hydraulic substation.
