But, whether existing Lubricating-oil Station electrical system only adopts pressure gauge to detect Lubricating-oil Station fuel feeding normal, once pressure gauge occurs after of short duration false fault, the false signal of lubricating station fault is easily provided to master-control room, cannot determine the accurate for oil condition of Lubricating-oil Station, this gives and uses enterprise to cause unnecessary trouble.
Model utility content
The deficiency existing for overcoming above-mentioned prior art, the utility model provides a kind of Lubricating-oil Station with accurate fuel feeding status alert function, and it can avoid pressure gauge to occur that of short duration false fault provides the generation of lubricating station fault false signal phenomenon to master-control room.
The technical scheme in the invention for solving the technical problem is: a kind of Lubricating-oil Station with accurate fuel feeding status alert function, comprise fuel tank, gear pump, one-way valve, safety valve, Double-tube net type filter, cooler and oil feed line, the oil-feed port of described gear pump is provided with pressure-detecting device, it is characterized in that, in oil feed line, be provided with flow detector; Described flow detector comprises flux signal device and flow warning circuit, described flow warning circuit comprises auxiliary reclay and the first tutorial light, the coil of described auxiliary reclay accesses power supply after connecting with the normal open switch of flux signal device, and the first normally-closed contact of described auxiliary reclay is connected in the current supply circuit of the first tutorial light.
Further, the second normally-closed contact of described auxiliary reclay is connected in the current supply circuit of low pressure alarming signal circuit, described low pressure alarming signal circuit comprises the buzzer and the second tutorial light that are arranged in master-control room, and described buzzer and the second tutorial light are connected in series.
Further, described flux signal device is arranged on described oil feed line mesolow oil outlet place.
Further, described pressure-detecting device comprises pressure gauge with electric contact.
The beneficial effects of the utility model are, the utility model detects by increasing flow of lubrication, whether normally not only can detect Lubricating-oil Station fuel feeding by pressure gauge, and also judge the accurate status of Lubricating-oil Station fuel feeding by detecting the flow information of lubricant oil simultaneously, avoid pressure gauge to occur that of short duration false fault provides the generation of lubricating station fault false signal phenomenon to master-control room, ensured the normal operation of main process equipment.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Fig. 1 is the warning circuit figure of Lubricating-oil Station flow of lubrication described in the utility model when normal;
Fig. 2 is the warning circuit figure of Lubricating-oil Station flow of lubrication described in the utility model when low.
In figure, LL: the normal open switch of flux signal device, KA: auxiliary reclay, HL1: the first tutorial light, HL2: the second tutorial light, BELL: buzzer.
Embodiment
A kind of Lubricating-oil Station with accurate fuel feeding status alert function of the present utility model, it comprises fuel tank, gear pump, one-way valve, safety valve, Double-tube net type filter, cooler and oil feed line, the oil-feed port of described gear pump is provided with pressure-detecting device, whether described pressure-detecting device comprises pressure gauge with electric contact, normal in order to detect Lubricating-oil Station fuel feeding according to charge oil pressure; Occur that for fear of pressure gauge of short duration false fault provides the generation of lubricating station fault false signal phenomenon to master-control room, in oil feed line, be provided with flow detector, judge in order to detect the flow information of lubricant oil in oil feed line whether Lubricating-oil Station breaks down.
As depicted in figs. 1 and 2, flow detector described in the utility model comprises flux signal device and flow warning circuit, described flux signal device is arranged on described oil feed line mesolow oil outlet place, described flow warning circuit comprises auxiliary reclay KA and the first tutorial light HL1, the coil of described auxiliary reclay KA accesses 220V power supply after connecting with the normal open switch LL of flux signal device, and the first normally-closed contact KA1 of described auxiliary reclay KA is connected in the current supply circuit of the first tutorial light HL1; The second normally-closed contact KA2 of described auxiliary reclay KA is connected in the current supply circuit of low pressure alarming signal circuit, described low pressure alarming signal circuit comprises the buzzer BELL and the second tutorial light HL2 that are arranged in master-control room, and described buzzer BELL and the second tutorial light HL2 are connected in series.In the specific implementation, described flux signal device has adopted the YXQ type flux signal device that switch pattern is AC two-conductor system to the utility model.
