Abstract
The utility model discloses a lubricating oil pump control circuit in a lubricating station and in particular relates to a control circuit for starting a standby pump when a main pump is overloaded. The control circuit also comprises a series branch circuit of a normally open point of a 1 <#> pump thermal relay FR1 and an intermediate relay KA 16, and a series branch circuit of a normally open point of a 2 <#> pump thermal relay FR2 and an intermediate relay KA 17. The normally open points of the intermediate relay KA 16 and the intermediate relay KA 17 are respectively and connected in parallel with normally closed point of an intermediate relay KA 9 and with two ends of a series circuit of a normally open point of a 2 <#> contactor and a normally open point of a 1 <#> contactor. The utility model provides the lubricating-station lubricating oil pump control circuit which can automatically start the standby oil pump when the main pump is overloaded and then tripped.
Description
(1) technical field
The utility model relates to a kind of Lubricating-oil Station lubricating pump control circuit, specifically is when main pump transships, and starts the control circuit of stand by pump.
(2) background technique
Lubricating-oil Station is applicable in the gear, bearing lubrication system of equipment such as metallurgy, mine, cement machinery, to guarantee the normal operation of equipment, increase the service life and the supporting use of top petrol tank also to can be used for non-pressure such as hydrostatic bearing lubricated.
Lubricating-oil Station is equipped with two gear pumps, next work of normal condition, and one is standby.If the accident of chance, when system pressure dropped to setting 0.1MPa, stand by pump put into operation, and when system pressure returned to normal value, stand by pump stopped automatically; If when system pressure continued to drop to setting 0.05MPa after the stand by pump work, system sent the hypotony alarm signal.It is main pump that its control circuit is selected a pump by integral switch, and this pump contactor is often driven auxiliary contact and also gone here and there in the stand by pump control loop, presses the main pump control switch so, and then main pump and stand by pump start simultaneously; Pressure relay is then controlled an auxiliary reclay in addition, and the normally closed point of this auxiliary reclay is gone here and there on the control loop of stand by pump, when oil pressure greater than 0.1MPa, pressure relay action, above-mentioned relay gets electric, its normally closed point disconnects, then stand by pump dead electricity and stopping.Yet, the situation when overload two trips if existing Lubricating-oil Station control circuit does not relate to main pump, when causing this situation to occur, stand by pump needs manual operation to start, thus the equipment that influences normally moves.
(3) summary of the invention
The utility model can't be when main pump trips because of overload at present Lubricating-oil Station lubricating pump control circuit, can not start the defective of stand by pump voluntarily, provide a kind of main pump if because of overload trips, the Lubricating-oil Station lubricating pump control circuit that stand by pump can start voluntarily.
The technical solution adopted in the utility model is:
The utility model Lubricating-oil Station lubricating pump control circuit, comprise the branch road that 1# pump contactor self-locking circuit, 2# pump contactor self-locking circuit and pressure relay SP1 connect with auxiliary reclay KA9, wherein the self-locking circuit of 1# pump contactor KM1,2# pump contactor KM2 is parallel with the normally closed point of auxiliary reclay KA9 respectively by integral switch SA and 2# pump contactor is often made war, the normal series circuit of making war of 1# pump contactor, and 1# pump control circuit, 2# pump control circuit are in series with the normally-closed contact of corresponding thermorelay FR1, thermorelay FR2 respectively; Also comprise the normal battle of 1# pump thermorelay FR1 and series arm and the normal battle of 2# pump thermorelay FR2 and the series arm of auxiliary reclay KA17 of auxiliary reclay KA16, be parallel to the series circuit two ends that the normally closed point of described auxiliary reclay KA9 is often made war with the 2# contactor respectively, the 1# contactor is often made war the normal battle of auxiliary reclay KA16, auxiliary reclay KA17 respectively.
Above-mentioned Lubricating-oil Station lubricating pump control circuit, described auxiliary reclay KA16 and KA17 are in parallel respectively or be in series with tutorial light HL4, tutorial light HL5.
The utilization of the utility model Lubricating-oil Station lubricating pump control circuit is a pump thermorelay action wherein, and its normal closed principle of making war is utilized this normal another pump action of control of making war.The thermorelay FR1 of the utility model 1# pump and 2# pump and the coil that is in series with auxiliary reclay KA16 and KA17 normal battle respectively of FR2, and auxiliary reclay KA17 is parallel to the series circuit of normally closed point of auxiliary reclay KA9 and the auxiliary normally opened contact of 2# pump contactor KM2, and auxiliary reclay KA16 connection is corresponding.A pump is a main pump when integral switch is selected wherein, and after the startup, then another pump also can move, and surpasses setting pressure by the time, and then pressure relay SP1 action is electric thereby auxiliary reclay KA9 gets, and its normally closed point disconnects, then stopping with pump.And when main pump transships, the action of its thermorelay, its normally opened contact closure, then the auxiliary reclay of series connection with it get electric, thereby this relay often leave a closure, thereby circuit short circuit that will be in parallel with it, stand by pump gets electric startup.Thereby realized working as main pump because of overload trip, then the automatically actuated purpose of stand by pump makes the lubricant oil of lubrication system supply and would not interrupt.
