(5) embodiment
A kind of specific embodiment as shown in the figure, this pressure, the adjustable oil supply loop of flow comprise by tank for coolant 1, threephase asynchronous 2, metering pump 3 and connecting pipeline, the skimmer circuit of forming by electromagnetic relief valve 11 and connecting pipeline etc., the working connection of forming by electric control one-way valve group 4, pressure gauge group 5, pressure measurement display unit 6, flow control valve 7, flow measurement display unit 8 and connecting pipeline etc., and the bypass of forming by flow control valve 7, Pilot operated check valve 9, solenoid directional control valve 10 and connecting pipeline etc.; Described working connection jointed rod and tank for coolant 1, working connection is connected with drilling rod by guide pin bushing 15 before the drilling rod, and make drilling rod face workpiece 16, and drilling rod is connected with drill unit 12 by guide pin bushing 13 behind the drilling rod, and guide pin bushing 13 is connected with smear metal and cooling liquid filtering separation device 14 behind the drilling rod.Skimmer circuit connects working connection and tank for coolant 1, and bypass connects working connection and tank for coolant 1.
Oil supply loop is divided into following three workflows:
One, oil supply loop idle cycle flow process
At first, starting threephase asynchronous 2, allowing the solenoid directional control valve of electric control one-way valve group 4 get electric commutation simultaneously makes described electric control one-way valve 4 close solenoid directional control valve with electromagnetic relief valve 11 to get electric commutation described electromagnetic relief valve 11 main valve plugs are opened, metering pump 3 is driven into cooling liquid the oil supply loop from tank for coolant 1, get back to again in the tank for coolant 1 by electromagnetic relief valve 11, realized oil supply loop idle cycle process.
Two, the pressure in the course of normal operation, flow control circuit
After finishing above-mentioned idle cycle process, the solenoid directional control valve dead electricity commutation that allows the solenoid directional control valve dead electricity of electric control one-way valve 4 reset simultaneously to make described electric control one-way valve 4 to be opened with electromagnetic relief valve 11 is closed described electromagnetic relief valve 11 main valve plugs, has only when the cooling liquid working pressure reaches the oil pressure relief that electromagnetic relief valve 11 sets and just can open.The cooling liquid that metering pump 3 is got can only enter the loop by electric control one-way valve 4, at this moment, the solenoid directional control valve 10 of control Pilot operated check valve 9 is in the normal state, cooling liquid enters the outside control mouth of Pilot operated check valve 9 by the runner of solenoid directional control valve 10, Pilot operated check valve 9 reverse openings, cooling liquid circulates in working connection and bypass simultaneously.Adjusting is installed in the flow control valve 7 in working connection and the bypass, to be installed in flow control valve 7 in the bypass is main the adjusting, to be installed in flow control valve 7 on the working connection is auxilliary the adjusting, in the adjustment process, note to observe pressure measurement display unit 6 and flow measurement display unit 8, pressure, Flow-rate adjustment to respective value.
Three, high pressurized overflow dashes row's smear metal flow process
In the deep hole processing process, smear metal is at drilling rod and stopped up in the shaped hole in the time of can't discharging, flow measurement display unit 8 detects the flow that enters in the working connection and reduces, the low alarm signal of flow impels control system to allow the solenoid directional control valve 10 of control Pilot operated check valve 9 get electric commutation, make cooling liquid can't enter the outside control mouth of Pilot operated check valve 9 by the runner of solenoid directional control valve 10, Pilot operated check valve 9 is closed, i.e. bypass blocks.At this moment, the coolant pressure that metering pump 3 is got raises until the oil pressure relief that electromagnetic relief valve 11 valve ports are opened, and dashes row's smear metal until discharging fully with this oil pressure relief, and low warning of flow eliminated.If still can not discharge smear metal in this way, the drilling main shaft can initiatively withdraw from, and stops boring.
More than be the workflow of pressure, the adjustable oil supply loop of flow.
