Abstract
An oil-gas recovery refueling machine comprises a composite fueling pump (7) which is arranged in the refueling machine body, and consists of an oil pump (8) and an oil-gas separator (4); a measurer (3) which connects with the oil feeding orifice of the refueling pump; and an oil gun (1) which connects with the measurer via a reverse coaxial hosepipe. The refueling machine is characterized in that one end of the outer oil transmitting pipe chamber (2) of the reverse coaxial hosepipe communicates with the oil outlet of the measurer (3), and the other end communicates with the oil feeding pipe chamber of the oil gun (1); one end of the central oil transmitting pipe chamber (9) of the reverse coaxial hosepipe communicates with the oil-gas recovery pipe chamber of the oil gun (1), and the other end communicates with the oil inlet of the composite refueling pump (7); the constant-pressure chamber of the oil-gas separator (4) in the composite refueling pump (7) is connected into a gas return duct (6) via a gas discharge opening (5) on a pump cover which connects with the constant-pressure chamber.
Description
Technical field
The utility model relates to a kind of oil gas that has the secondary gas recovery system for oil and reclaims fuel charger.
Background technology
The secondary gas recovery system for oil is that the oil gas around the oil gun mouth is recovered to oil storage system (referring generally to oil tank), prevents that it from entering atmosphere, contaminated environment.
Secondary gas recovery system for oil commonly used at present divides two kinds: balanced system and vacuum-assisted system.
Balanced system: be a kind of closed recovery system, comprise that oily vapour reclaims horn cover and the coaxial hose on rifle, the muzzle.The flexible pipe internal layer is an oil outlet, and skin is oily vapour Through Flow Line (TFL).Its principle is to utilize in the refueling process to produce suction owing to liquid level in the oil tank descends, thereby by closed pipeline the oily vapour that produces in the oil tank of vehicle is recovered to oil tank.The advantage of this system is simple in structure, what and the minimizing self-equalizing of fluid volume of reclaimed oil vapour.Its shortcoming is: to the requirement height of tightness, and the oil gun heaviness, soft cover is fragile.In addition, because its recovery is more constant than V/L (volume and the volume read-out volume ratio that refer to reclaimed oil vapour), when increasing, oily vapour can cause that oily vapour is excessive.
Vacuum-assisted system (its principle is seen Fig. 1):, be a kind of open recovery system with vacuum pump reclaimed oil vapour.Its characteristics are exactly that the suction that utilizes vacuum pump to produce when giving group refueling carries out the oil gas recovery.This system mainly reclaims rifle, reverse coaxial recovery flexible pipe by oil gas and reclaims pump and form.During oiling, fluid flows out from the skin of coaxial hose, injects oil tank of vehicle by oil gun; Simultaneously, the oil gas of generation is entering oil gun from the aperture that reclaims around the rifle head under the effect of reclaiming pump, enters the recovery pump through the internal layer of coaxial hose, flow back into sunken oil storage then.Its weak point needs increase separately to overlap by pipeline and reclaims the recovering mechanism that pump is formed, and causes the increase of its cost.
Summary of the invention
The purpose of this utility model provides the more rational oil gas of a kind of structure to reclaim fuel charger just at existing weak point in the above-mentioned prior art.
Fuel charger of the present utility model has adopted the oil gas of vacuum-assisted system to reclaim oil gun, reverse coaxial hose, removed the recovery pump, carrying pump (sundstrand pump) with fuel charger replaces, have pump oil, Oil-gas Separation, three kinds of functions of oil gas recovery simultaneously, reduce the fuel charger cost, made the fuel charger structure simpler, absorbed the light advantage of oil gun that has oil gas recovery function in the vacuum-assisted system simultaneously.
The purpose of this utility model can realize by following technique measures:
Oil gas of the present utility model reclaims fuel charger and comprises the compound type fuel charger that is made of jointly oil pump and oil separator that is arranged in the fuel charger body, the metering device that is connected with the fuel charger fuel feeding mouth of pipe, the oil gun that is connected with metering device by reverse coaxial hose, one end of the outer oil transportation tube chamber of described reverse coaxial hose is connected with the metering device oil outlet, the other end is connected with the fuel feeding tube chamber of oil gun, one end of the center oil transportation tube chamber of described reverse coaxial hose reclaims tube chamber with the oil gas of oil gun and is connected, the other end is connected with oil pump oil inlet in the compound type fuel charger, and the common pressure chamber of the oil separator in the compound type fuel charger inserts return-air duct by the exhausr port on the coupled pump cover.
Principle of work of the present utility model is as follows: during oiling, the sundstrand pump of fuel charger is delivered to the oil separator of sundstrand pump with oil sucking-off from oil tank, and the gas-liquid mixture after the separation enters into the oil separator common pressure chamber; The oil that does not contain gas enters through the outer oil transportation tube chamber of other elements such as metering device, electromagnetic valve by reverse coaxial hose has the oil gun that oil gas reclaims function, and logical oil gun joins oil in the automotive oil tank.Meanwhile, oil gas around the oil gun, under the suction of sundstrand pump oil inlet, the oil gas that aperture around nozzle rifle head enters oil gun reclaims tube chamber, center oil transportation tube chamber through reverse coaxial hose is inhaled into the sundstrand pump oil inlet, after the sundstrand pump oil separator separates, enter the oil separator common pressure chamber, get back in the oil tank by the return-air duct in exhausr port, the oil station on the coupled pump cover again.By above structure, fuel charger has been realized the oil gas recovery at gas filed simultaneously.
The utility model not only can make the fuel charger cost be minimized compared to existing technology, and can make its structure simple more, reasonable.
