The solenoid valve control circuit comprises a No.1 device solenoid valve stop button SB2; a No.2 device solenoid valve stop button SB4; a No.1 device solenoid valve operation intermediate relay KA1, a solenoid valve YA1 and a solenoid valve YB1 disposed on the lower stage of the No.1 device solenoid valve stop button SB2, and a No.2 device solenoid valve operation intermediate relay KA2, a solenoid valve YA2 and a solenoid valve YB2 disposed on the lower stage of the No.2 device solenoid valve stop button SB4; and a No.1 device contactor auxiliary normal open point KM1 and a No.2 device contactor auxiliary normal open point KM2 which are respectively connected with a time relay KT1 and a time relay KT2 in series. The normal close points of the two time delays are respectively connected in series between the No.1 device solenoid valve stop button SB2 and the lower stage thereof and between the No.2 device solenoid valve stop button SB4 and the lower stage thereof. The utility model provides a solenoid valve control circuit for a high/low voltage thin oil station capable of automatically switching the solenoid valve off.
Description
(1) technical field
The utility model relates to a kind of high low pressure Lubricating-oil Station solenoid valve control circuit, especially relates to an a kind of station two machine high low pressure Lubricating-oil Station high-pressure solenoid valve control circuits.
(2) background technique
A present station two machine high low pressure Lubricating-oil Station principles are that a Lubricating-oil Station is two equipment fuel feeding, provide lubricant oil to offer machine spindle bearings such as coal pulverizer.Equipment is to provide lubricated by low pressure pump in normal operation, and high-pressure service pump uses at device start or when stopping.Before opening of device, at first open low pressure pump, after low pressure pump is stable, opens again and wait to offer high-pressure solenoid valve fully, after high-pressure solenoid valve is opened, drive high-pressure service pump (high-pressure service pump is only given an equipment fuel feeding, by the conversion of 3-position 4-way solenoid directional control valve) again.High-pressure system is not established fuel tank separately, and fluid is sent into bearing by sucking-off in the low pressure pump oil outlet.When pressure reaches certain value (being set pressure), main shaft will float under pressure, promptly start equipment this moment, after equipment operation is steady, automatically stop high-pressure service pump, lubricated by the low pressure pump fuel feeding, can close high-pressure system oil circuit valve (being three-position four-way valve) this moment, open another equipment high-pressure system, open high-pressure service pump again and start another equipment.When high-pressure system also is used for equipment downtime, promptly open earlier high-pressure service pump, when pressure reaches certain stationary value, can stop equipment (two equipment are shut down respectively, and mode of operation is the same with boot program), after safety comes to a complete stop, stop high-pressure service pump, stop low pressure pump again.But owing to present above-mentioned solenoid valve control circuit and relevant device interlock, that is to say that then solenoid valve is in electriferous state all the time as long as equipment is turning round, such one is that energy consumption increases, and solenoid valve is for a long time charged besides burns easily.
(3) summary of the invention
The utility model is controlled by the equipment operation state at present high low pressure Lubricating-oil Station solenoid valve control circuit, cause the energy consumption height, and the defective that causes solenoid valve to burn easily provides a kind of high low pressure Lubricating-oil Station solenoid valve control circuit that can cut off the power supply for solenoid valve automatically.
The technical solution adopted in the utility model is:
