Abstract
The utility model discloses a self-input circuit of standby pump in high-low voltage rare oil station, solving the problem that at present the standby pump can not self-input after main pump is tripped due to fault. The utility model has the advantages of simple structure, convenient use, and that standby pump can perform automatic input after main pump is tripped due to fault. The utility model comprises a main pump control circuit that is connected in parallel and attached with intermediate relay constant-off contact point, a standby pump control loop, and a low oil pressure standby input circuit that is composed of intermediate relays, also comprises a main pump fault input loop and a standby fault input circuit that both are connected in parallel, simultaneously a conversion switch SA 1 and a conversion switch SA2 are respectively arranged outside the main pump control loop and the intermediate relay constant-off contain point of the standby pump control loop.
Description
Technical field
The utility model relates to the equipment of hauling oneself willingly into of pump, relates in particular to a kind of high low pressure Lubricating-oil Station stand by pump and hauls oneself willingly into circuit.
Background technique
The low pressure pump of high low pressure Lubricating-oil Station has two, and under normal circumstances, one of an operation is standby, selects the main pump of low pressure pump by throw over switch SA, and when oil pressure was lower than 0.1MPa, stand by pump started, and when oil pressure during greater than 0.1MPa, stand by pump stops automatically.But behind the main pump fault trip, stand by pump can't drop into voluntarily, and influence is produced.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem that present stand by pump can't drop into voluntarily behind the main pump fault trip, provide a kind of have simple in structure, easy to use, after main pump hinders tripping operation for some reason, stand by pump can be carried out the high low pressure Lubricating-oil Station stand by pump of advantages such as automatic switching and haul oneself willingly into circuit.
For achieving the above object, the utility model adopts following technological scheme:
A kind of high low pressure Lubricating-oil Station stand by pump is hauled oneself willingly into circuit, it comprises the main pump control loop that has the auxiliary reclay normally-closed contact, stand by pump control loop in parallel and the low oil pressure stand by pump switching loop of being made up of auxiliary reclay, it comprises that also main pump fault in parallel drops into the loop and the stand by pump fault drops into the loop, is respectively equipped with throw over switch SA1 and throw over switch SA2 at the main pump control loop and the stand by pump control loop auxiliary reclay normally-closed contact outside simultaneously.
Described main pump fault drops into the loop and is made up of the auxiliary reclay KA2 and the thermorelay FR1 normally opened contact of series connection.
Described stand by pump fault drops into the loop and is made up of the auxiliary reclay KA3 and the thermorelay FR2 normally opened contact of series connection.
Described main pump control loop comprises contactor KM1, and it is connected with thermorelay FR1 normally-closed contact; Thermorelay FR1 normally-closed contact serial connection collateral contact group, this group collateral contact is connected with throw over switch SA1; The collateral contact group comprises contactor KM2 normally opened contact, the auxiliary reclay KA1 normally-closed contact of normally opened contact, auxiliary reclay KA3 normally opened contact and the series connection of contactor KM1.
Described stand by pump control loop comprises contactor KM2, and it is connected with thermorelay FR2 normally-closed contact; Thermorelay FR2 normally-closed contact serial connection collateral contact group, this group collateral contact is connected with throw over switch SA2; The collateral contact group comprises contactor KM1 normally opened contact, the auxiliary reclay KA1 normally-closed contact of normally opened contact, auxiliary reclay KA2 normally opened contact and the series connection of contactor KM2.
Described low oil pressure stand by pump switching loop is made up of the auxiliary reclay KA1 and the pressure relay SP1 normally opened contact of series connection.
Contact SA1-3, the SA1-2 that the utility model is opened conversion moves to the normally closed top of KA1, increases auxiliary reclay KA2, KA3.After main pump tripping operation, FR1 or FR2 adhesive, KA2 or KA3 get electric, KA2 or the KA3 closure of often making war then, will in KA2 or KA3 mutually and the contact short circuit, then stand by pump no longer is stressed and the restriction of main pump operation contact, starts voluntarily, for grinding machine provides lubricated.
The beneficial effects of the utility model are: simple in structure, easy to use.
