Abstract
The utility model discloses an automatic continuable oiling device for a roots blower oil tank. The automatic continuable oiling device comprises an oil storage tank, an oil guide pipe, an electromagnetic valve YV, a sensor and a control circuit, wherein the oil storage tank is arranged on the upper end of the blower oil tank, the oil guide pipe is communicated with the blower oil tank and the oil storage tank, the electromagnetic valve YV is arranged on the oil guide pipe, and the sensor is located in an oil level display window of the blower oil tank; an input end of the control circuit is connected with the sensor, and an output end of the control circuit is connected with the electromagnetic valve YV. According to the automatic continuable oiling device, the oil level of the oil tank can be detected by the sensor, the on and off of the electromagnetic valve can be controlled through the control circuit, when the oil tank lacks of oil, oil can be injected into the oil tank without the need of stopping the machine, and oil in the oil tank cannot splash, thus guaranteeing the safety of work staff; in addition, by using the device, the work staff does not need to always observe the oil level display window of the oil tank to judge that whether oil injection is needed or not.
Description
Technical field
The utility model 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 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 spilling can be scalded staff; And existing blower fan fuel tank is provided with oil level window, need staff often to observe this oil level window and judge whether oiling, very inconvenient.
