Embodiment
[embodiment 1]
On device as shown in Figure 1, comprise coolant bottle 4, vacuum pump 18, heat exchanger 21, it is characterized in that the cooling liquid outlet pipeline of coolant bottle 4 is divided at least two-way after coolant pump 8, one tunnel is connected with the chuck cooling liquid inlet N1 on vacuum pump 18, another road is connected with the axle center cooling liquid inlet N4 on vacuum pump 18, chuck cooling liquid outlet N3 on vacuum pump 18 is connected by the tube-side inlet of pipeline with heat exchanger 20 with axle center cooling liquid outlet N6, tube side outlet is connected with coolant bottle 4, described heat exchanger 20.
When vacuum pump operation, cooling unit starts simultaneously, and intrasystem electric valve, solenoid valve, coolant pump 8 and fan 23 start simultaneously.Cooling liquid is through electric valve 7, coolant pump 8, and one-way valve 10 enters the cooling pipe of vacuum pump 18, by the temperature value of teletransmission thermometer 20, judges whether vacuum pump discharges temperature reaches setting value.(1) if temperature does not reach setting value, then only open the solenoid valve 14 of chuck cooling, cooling liquid is through the chuck of vacuum pump set, inject from the cooling liquid inlet N1 of front cover, by the pump housing, the cooling liquid exhaust port N3 on the pump housing discharges, and takes away the heat that unit produces, enter heat exchanger 20, cooling liquid walks the tube side of heat exchanger, and the cooling liquid heat after intensification is taken away by fan 23, and fan 23 is driven by motor 22, cooling liquid after cooling gets back to coolant bottle, continues to participate in cool cycles.(2) if temperature reaches setting value, then open the solenoid valve 14 of chuck cooling and the solenoid valve 17 of axle center cooling simultaneously, cooling liquid is injected from the inlet N4 of the inlet N1 of chuck cooling and axle center cooling simultaneously, after the pump housing and screw rod, discharge from the exhaust port N3 of chuck cooling and the exhaust port N6 of axle center cooling respectively, converge into a road afterwards, get back to heat exchanger 20 and carry out heat exchange.
When cooling liquid is lossy, inject cooling liquid can be added by the coolant injection mouth 1 on coolant bottle 4.Level meter 2 on tank can be real-time the amount reflecting cooling liquid in tank, when liquid level is in respect of fault, can also show that the situation of pot liquid observed by mirror 6 by storage tank.Thermometer 3 on tank can monitor the temperature of pot liquid the moment.
If in coolant bottle 4 during the contaminated or device checking maintenance of liquid, mouth 5 can be drenched by leading on coolant bottle and put only.
The outlet pressure of coolant pump 8 measured by pressure gauge 9 on pipeline, can judge that whether the operation of pump is normal, whether occur cavitation erosion or blocking.One-way valve 10 on pipeline can ensure that cooling liquid does not flow backwards.Flowmeter 11 on pipeline can measure the circular flow of cooling liquid in real time.Show that mirror 13 and pipeline show that mirror 16 can observe the mobility status of cooling liquid by pipeline, judge whether pipeline blocks.
When vacuum pump 18 needs maintenance, manual-lock ball valve 12 and ball valve 15, the cooling liquid in discharging tube road and unit, deviates from vacuum pump, keeps in repair in system.
