Detailed description of the invention
Through finding and analyzing, adopting the coolant circulation system of prior art, the safety coefficient that vacuum hotpressing stove runs is relatively low, and time serious, the reason that vacuum hotpressing stove cannot be properly functioning is as follows:
(1) in prior art, earth cooling liquid pool lacks the monitoring device that the volume to coolant therein is monitored, so, when the coolant in the coolant reservoirs of underground is too much, constant frequency returns the frequency constant that draws water of liquid pump 15, then pump-out keeps constant, the too much coolant in coolant reservoirs is descended to be pumped in this wise, under meeting spot, the coolant in coolant reservoirs overflows the phenomenon of coolant reservoirs, and the coolant of spilling easily flows into the circuit control device entering vacuum hotpressing stove and leaky occurs.When the coolant in the coolant reservoirs of underground is very few, constant frequency is returned the frequency of drawing water of liquid pump 15 and is kept constant equally, then pump-out keeps constant, and constant frequency is returned the motor of liquid pump 15 and will be burned off, thus coolant circulation cannot be realized.
(2) the cement liquid storage pool liquid outlet in coolant circulation system of the prior art to liquid feeding pump liquid inlet, liquid feeding pump liquid inlet to vacuum hotpressing stove liquid inlet, earth cooling liquid pool liquid outlet to constant frequency returns liquid pump liquid inlet, constant frequency returns liquid pump liquid outlet between cement liquid storage pool liquid inlet for pipeline.
Coolant pressure in above-mentioned pipeline is detected by the coolant circulation system shortage of prior art, and the pressure of the coolant in pipeline is too low, it is impossible to enough vacuum hotpressing stove is carried out enough coolings.Particularly in the production phase using vacuum hotpressing stove, if the pressure of the coolant in pipeline is too low, can there is the serious risk of vacuum hotpressing stove fusing.The pressure of the coolant in pipeline is too high, and coolant pipeline has the risk broken.
(3), in prior art, earth cooling liquid pool is built by cement and is formed, so, if earth cooling liquid pool contains more coolant, outwards oozing out from earth cooling liquid pool, the coolant oozed out rolls up stream, flows into the circuit control device of vacuum hotpressing stove and leaky occurs.
(4) in prior art, the recess channels that vacuum hotpressing stove liquid outlet is built into for cement between earth cooling liquid pool liquid inlet, coolant in this recess channels is also easily outwards oozed out, and when the coolant outwards oozed out runs up to a certain amount of, is susceptible to leaky equally.
(5) the cement liquid storage pool 11 in coolant circulation system of the prior art is also that cement is built and formed, the volume of cement liquid storage pool 11 is relatively larger, when the cooling liquid measure in cement liquid storage pool 11 is more, coolant in cement liquid storage pool 11 there will be the more serious phenomenon that outwards seeps water of ratio, when the coolant oozed out is too much, also easily flows into the circuit control device entering vacuum hotpressing stove and leaky occurs.It addition, the voltage endurance capability of cement liquid storage pool 11 and intensity are relatively low, so, the limited height of the cement liquid storage pool 11 of prior art, but, in order to store more coolant, the floor space of cement liquid storage pool is bigger.So, the ground being positioned at cement liquid storage pool 11 can sink, the less stable of whole vacuum hotpressing furnace apparatus.
(6), in prior art, cement liquid storage pool 11 is as the liquid coolant sources in coolant circulation system.But, if liquid feeding pump and time liquid pump break down, the coolant in cement liquid storage pool would not flow to vacuum hotpressing stove place, it may appear that situation about cannot vacuum hotpressing stove 13 be cooled down.
(7), in prior art, the first civil power returns liquid pump 15 as power supply be electrically connected with liquid feeding pump 12 and constant frequency.But, in actual production process, as occurred shutting off power in emergency, liquid feeding pump 12 and constant frequency return liquid pump 15 and just cannot work.Coolant in coolant circulation system can stop at the circulation in coolant circulation system, situation about cannot vacuum hotpressing stove 13 be cooled down occurs, affects the properly functioning of vacuum hotpressing stove 13.
In order to solve above-mentioned technical problem, the invention provides a kind of coolant circulation system, adopt the coolant circulation system of the present invention can improve the safety coefficient of vacuum hotpressing stove.
