Description
Technical field
This utility model relates to a kind of fuel loading system, specifically a kind of automotive engine test experiment fuel loading system.
Background technology
As is known to the person skilled in the art, the oiling of motor vehicles be large commercial vehicle fleet (such as bus company) operator and HGV operator faced by subject matter.The overwhelming majority in these vehicles is diesel-driven and oiling is generally carried out gas station refueling operation person at night.In addition to obvious inconvenience, if vehicle oil plant on road exhausts, public transportation operator the punishment caused is the most serious.Then, it is by mean of refueling to overflowing strategy to guarantee to refuel to its capacity fuel tank to the most common process of these group refuelings.
This strategy brings obvious overflow problem.This alternative needs oiling person to stop refueling to see whether that fuel oil occurs in the cervical region of fuel tank.This oiling method creates suitable time waste for the vehicle that each refuels.The direct result of said method is that fuel oil spilling constitutes the waste of substantial amounts of fuel oil and the most also sinks money.
Summary of the invention
The purpose of this utility model is to provide a kind of automotive engine test experiment fuel loading system, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of automotive engine test experiment fuel loading system, including PLC main frame, signal sending end, effusion meter, oil-immersed pump, liquid level sensor, pressure transmitter, laboratory building electromagnetic valve, outdoor solenoid valve and gas supply electromagnetic valve, described PLC main frame connects signal sending end, effusion meter, oil-immersed pump, liquid level sensor, pressure transmitter, laboratory building electromagnetic valve, outdoor solenoid valve and gas supply electromagnetic valve respectively.
As further program of the utility model: described signal sending end includes user's stand, laboratory HC or fire-alarm.
As further program of the utility model: described laboratory building electromagnetic valve, outdoor solenoid valve and gas supply electromagnetic valve are respectively positioned in air pump station.
As further program of the utility model: described liquid level sensor and oil-immersed pump are all located in waste oil storage tank, and waste oil storage tank is placed in air pump station.
As further program of the utility model: described PLC main frame controls emergency bearing oil pump also by standby electricity magnet valve.
As further program of the utility model: be additionally provided with low grade oil tank and gasoline tank in described air pump station, in low grade oil tank and gasoline tank, also it is respectively equipped with a liquid level sensor.
As this utility model further scheme: described flow is calculated as 3, it is respectively arranged in emergency bearing oil pump, low grade oil tank and gasoline tank.
Compared with prior art, the beneficial effects of the utility model are: this utility model automotive engine test experiment fuel loading system simple in construction, low cost, safety is high.
Accompanying drawing explanation
Fig. 1 is the electrical principle block diagram of automotive engine test experiment fuel loading system.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of automotive engine test experiment fuel loading system, including PLC main frame, signal sending end, effusion meter, oil-immersed pump, liquid level sensor, pressure transmitter, laboratory building electromagnetic valve, outdoor solenoid valve and gas supply electromagnetic valve, described PLC main frame connects signal sending end, effusion meter, oil-immersed pump, liquid level sensor, pressure transmitter, laboratory building electromagnetic valve, outdoor solenoid valve and gas supply electromagnetic valve respectively；Described signal sending end includes user's stand, laboratory HC or fire-alarm；Described laboratory building electromagnetic valve, outdoor solenoid valve and gas supply electromagnetic valve are respectively positioned in air pump station；Described liquid level sensor and oil-immersed pump are all located in waste oil storage tank, and waste oil storage tank is placed in air pump station；Described PLC main frame controls emergency bearing oil pump also by standby electricity magnet valve；It is additionally provided with low grade oil tank and gasoline tank in described air pump station, in low grade oil tank and gasoline tank, is also respectively equipped with a liquid level sensor；Described flow is calculated as 3, is respectively arranged in emergency bearing oil pump, low grade oil tank and gasoline tank.
Operation principle of the present utility model is: refer to Fig. 1, when PLC main frame receives the signal of signal sending end, can be automatically switched the gas supply electromagnetic valve of fuel feeding air pump in (or close) air pump station, outdoor solenoid valve and laboratory building electromagnetic valve, it is provided with liquid level sensor in waste oil storage tank, when in tank, liquid level arrives a certain height, waste oil liquid level warning, oil-immersed pump starts simultaneously, and waste oil is discharged sump tank.
The effect of standby electricity magnet valve: when an oil pump fault or pipeline pressure burst, gas supply electromagnetic valve, outdoor solenoid valve and laboratory building closed electromagnetic valve, start emergency bearing oil pump, it is ensured that the safety of system.
PLC main frame can adjust the unlatching situation of oil pump according to the force value of pressure transmitter feedback, it is ensured that user's request force value.
PLC main frame can automatically read oil consumption flow according to effusion meter.
