Abstract
The invention discloses a Roots blower oil tank automatic oil filling device allowing continuous oil filling. The device comprises an oil storage box, an oil guide pipe, an electromagnetic valve YV, a sensor and a control circuit. The oil storage box is arranged at the upper end of a fan oil box, the oil guide pipe is communicated with the fan oil box and the oil storage box, the electromagnetic valve YV is arranged on the oil guide pipe, the sensor is located in an oil level display window of the fan oil box, the input end of the control circuit is connected with the sensor, and the output end of the control circuit is connected with the electromagnetic valve YV. The sensor is used for detecting the oil level of the oil boxes, and accordingly the control circuit controls connection and disconnection of the electromagnetic valve; when oil in the oil boxes is not enough, oil can be filled into the oil boxes with no need of halt, the oil in the oil boxes can not spill, and therefore safety of workers is guaranteed. Besides, the workers do not need to often observe the oil level display window of the fan oil box to judge whether oil filling is needed when the device is used.
Description
Technical field
The present invention relates to a kind of tank filling device, is a kind of roots blower fuel tank automatic oiling device of oiling continuously specifically.
Background technique
Existing blower fan fuel tank, all with oil hole, need to, when the blower fan state of rest, be opened oil hole and be carried out oiling during oiling.But, there is the continuous operating time of a lot of roots blowers longer, if fuel tank oil starvation in running, the blower fan ability oiling that needs to stop, once fan parking, can cause larger economic loss, if do not shut down, directly carry out oiling, because tank pressure is larger, and oil temperature is high, the oil spilt can be scalded the staff; And existing blower fan fuel tank is provided with the oil level window, needs the staff often to observe this oil level window and judges whether oiling, very inconvenient.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art existence, the object of the present invention is to provide a kind of roots blower fuel tank automatic oiling device of oiling continuously.
In order to address the above problem, the present invention is by the following technical solutions: a kind of roots blower fuel tank automatic oiling device of oiling continuously, comprise fuel reserve tank, oil guide pipe, solenoid valve YV, sensor and control circuit, described fuel reserve tank is arranged on blower fan fuel tank upper end, described oil guide pipe is communicated with blower fan fuel tank and fuel reserve tank, described solenoid valve is arranged on oil guide pipe, and described sensor is positioned at the oil level display window of fuel tank; Described control circuit input end is connected with sensor, and output terminal is connected with solenoid valve.
Described control circuit comprises single-chip microcomputer, triode Q11, diode D1, relay and some resistance and electric capacity; The IN interface of the P1 of described single-chip microcomputer, P0 and A/D modular converter is connected with the U0 interface respectively at STATUS, the ST of sensor; The P2 interface of single-chip microcomputer is connected with the B pin of triode Q11; The positive pole of diode D1 is connected with the C pin of triode Q11, negative pole connecting circuit access voltage VCC; The coil KM1 of described relay is in parallel with diode D1, and the normally opened contact KM1 of relay connects with solenoid valve YV.
Described sensor is photoelectric sensor.
Described solenoid valve is Unidirectional solenoid valve, and its inlet opening is connected with fuel reserve tank by oil guide pipe, and delivery outlet is connected with fuel tank by oil guide pipe.
