Two pumps device control mode conventional in prior art is: position switch is allocated to " the main 2# of 1# is standby ", and start 1# pump, 1# pump is started working, when Lubricating-oil Station oil pressure reaches meta, 2# pump automatic operation for subsequent use, when Lubricating-oil Station oil pressure attains to a high place, 1# pump work, 2# pump air pump inoperative for subsequent use.2# pump work is allowed if now want, 1# pump is as stand by pump, after needing 1# pump out of service, position switch is allocated to " the main 1# of 2# is standby ", restarts 2# pump, 2# starts pump work, because Lubricating-oil Station oil pressure reaches meta, 1# stand by pump automatic operation, when Lubricating-oil Station oil pressure attains to a high place, 2# pump work, 1 # air pump inoperative for subsequent use.
This equipment electrical system Problems existing: if 1 main pump operation irregularity, must change two oil pumps and run setting, if in charged handoff procedure, because oil pump quits work, cause not fuel feeding, cause a hidden trouble to main frame lubricating point to equipment lubrication point.If 2 main pump thermorelay overloads are stopped transport, could start when stand by pump needs oil pressure to reach meta, in the process, because oil pump quits work, not fuel feeding be caused to equipment lubrication point, main frame lubricating point is caused a hidden trouble.
Summary of the invention
For solving the problem, ensure lubrication system pressure stability, and don't allow main frame to stop transport, and do not cause lubricating point oil-break, the utility model provides a kind of thin oil lubricating device hydraulic pump control system, it comprises, and 1# oil pump controlling circuit in parallel and 2# oil pump controlling circuit and throw over switch 1# pump main 2# pump are standby and 2# pump main 1# pump is standby, this control gear also comprise one made war formed by the normally closed point of auxiliary reclay KA1, the normal of FR1, FR2 open, stop stand by pump device; The oil pump on off control loop be composed in series by auxiliary reclay KA2, normally closed switch SB1, normal open switch SB2, oil pump on off control loop is in parallel with 1# oil pump controlling circuit and 2# oil pump controlling circuit; 1# pump main 2# pump is made war for opening pump condition KA2 with the main 1# pump of 2# pump for having connected simultaneously.
Further, be also provided with start and stop pump switch KA2 between described 1# oil pump controlling circuit and 2# oil pump controlling circuit, the switch that KA1 and thermorelay FR1 controls and the switch in parallel that thermorelay FR2 controls complete the on off control of stand by pump.
Further, described 1# oil pump controlling circuit comprises the KA2 normal open switch of series connection, the main 2# pump of 1# pump for SA2-1 normally closed switch, thermorelay FR1 normally closed switch, contactor KM1, the tutorial light HL1 in parallel with KM1.
Further, described 2# oil pump controlling circuit comprises the KA2 normal open switch of series connection, the main 1# pump of 2# pump for SA2-2 normally closed switch, thermorelay FR2 normally closed switch, contactor KM2, the tutorial light HL2 in parallel with KM2.
Useful point of the present utility model is: 1# pump and 2# pump share a startup, stop button, and position switch is allocated to " the main 2# of 1# is standby ", by " pump start ", 1# pump and 2# pump work simultaneously, when Lubricating-oil Station oil pressure reaches high level, 1# pump work, 2# air pump inoperative for subsequent use.
Allow if want 2# pump work, 1# pump be stand by pump, directly position switch is allocated to the main 1# of 2# standby, do not need by " oil pump stopping ", now 2# pump work, 1# pump is as stand by pump.In this charged handoff procedure, 1# pump and 2# pump switch instantaneously, do not quit work, and do not impact equipment lubrication point fuel feeding.
This device it be in the control system principle of JB/T8522 in conjunction with marketplace user demand redesign for charged switching can be carried out to major-minor oil pump under the non-stop-machine operating mode of thin oil lubricating device, too increase thermal protection for motors and automatically start emergency bearing oil pump function.The utility model structure is simple, easy to use, can ensure electrical system stable operation, lubrication system pressure stability can be ensured, ensure when switching major-minor oil pump not cause lubricating point oil-break, main frame is not stopped transport, and meet the standby pump standby time is the usage requirement that should switch in time after a week simultaneously.
Accompanying drawing explanation
Fig. 1 is control circuit figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
A kind of thin oil lubricating device hydraulic pump control system as shown in Figure 1, it comprises 1# oil pump controlling circuit in parallel and 2# oil pump controlling circuit, and throw over switch 1# pump main 2# pump is standby and 2# pump main 1# pump is standby, this control gear also comprise one made war formed by the normally closed point of auxiliary reclay KA1, the normal of FR1, FR2 open, stop stand by pump device; The oil pump on off control loop be composed in series by auxiliary reclay KA2, normally closed switch SB1, normal open switch SB2, oil pump on off control loop is in parallel with 1# oil pump controlling circuit and 2# oil pump controlling circuit; 1# pump main 2# pump is made war for opening pump condition KA2 with the main 1# pump of 2# pump for having connected simultaneously.
Also be provided with start and stop pump switch KA2 between described 1# oil pump controlling circuit and 2# oil pump controlling circuit, the switch that KA1 and thermorelay FR1 controls and the switch in parallel that thermorelay FR2 controls complete the on off control of stand by pump.
