The utility model water circulation system running explanation:
At first start hot and cold water during the utility model test and make part, the compressor 15 of refrigeration system absorbs heat the evaporator 16 of cold water storage cistern 17 by cold-producing medium, makes condenser 14 heat releases of boiler 13, thereby produce cold water and hot water in cold water storage cistern 17 and boiler 13.Cold water storage cistern 17 makes cold water temperature keep certain by first temperature probe 35 and temperature controller control compressor 15.The hot water temperature controls automatic constant temperature heating devices 12 by second temperature probe 5 of attached hot case 11 to make water temperature keep certain.
The cold water for preparing, hot water are supplied to inner core controlled temperature cabinet 24 and outer coil pipe controlled temperature cabinet 7 (common calorimetric urceolus is replaced by outer coil pipe) respectively by first solenoid valve 19, second solenoid valve 18, the 3rd solenoid valve 9 and the 4th solenoid valve 10 in native system.Outer coil pipe controlled temperature cabinet 7 temperature are provided with generally than about the high 1K of room temperature, and inner core controlled temperature cabinet 24 temperature should be set by GB (GB/T213-2003), generally than about outer coil pipe controlled temperature cabinet 7 low 1K.
The temperature adjustment process of outer coil pipe controlled temperature cabinet 7 and inner core controlled temperature cabinet 24 is such: when the temperature inside the box is lower than setting value, the 3rd temperature probe 36 or the 4th temperature probe 37 send temperature signal to temperature controller, after temperature controller compares signal and setting value, the 3rd solenoid valve 9 or the 4th solenoid valve 10 controlled on the attached hot case 11 are opened, inject hot water to controlled temperature cabinet, then the 3rd solenoid valve 9 or the 4th solenoid valve 10 are closed to reach setting value up to the temperature inside the box; When the temperature inside the box is higher than setting value, after temperature probe sends temperature signal to temperature controller, temperature controller will record signal and setting value compares, first solenoid valve 19 or second solenoid valve 18 on the control cold water storage cistern 17 are opened, inject cold water to controlled temperature cabinet, reach setting value up to the temperature inside the box, then first solenoid valve 19 or second solenoid valve 18 are closed.The temperature inside the box is gone round and begun again to equating by unequal with design temperature like this, thereby realizes that mobile equilibrium reaches the constant relatively purpose of temperature.
The cyclic process of water is such in the experiment:
Inner core controlled temperature cabinet 24 by first pump 26 with water through last automatically controlled cone valve 2 to measuring cup 1, when last automatically controlled cone valve 2 goes to the water route that is cut to first pump 26 when discharging water the position, open to the water route of inner core 4, water flows into inner core 4 from measuring cup 1, after having put, measuring cup 1 water promptly begins test, burn in the oxygen bomb heat that generated of sample raises inner core 4 water temperatures in the test, after the off-test down automatically controlled cone valve 28 open inner core 4 water by often driving the 5th solenoid valve 25, put into attached water case 21.The effect of attached water case 21 is 1. to regain inner core 4 test water; 2. supply water for boiler 13, cold water storage cistern 17 by the 4th pump 34; 3. cool off by the 3rd pump 23 and 20 pairs of test water of cooling tube; Supply water 4. for inner core controlled temperature cabinet 24; Externally coil pipe controlled temperature cabinet 7 carries out water yield adjusting.
The water of outer coil pipe controlled temperature cabinet 7 pumps water to outer coil pipe 3 by second pump 6, and outer coil pipe 3 backwater still turn back to outer coil pipe controlled temperature cabinet 7, through temperature adjustment once more, for recycling.
The utility model adopts indirectly two temperature-controlling systems, its feature is: the first, condenser 14 (or other refrigerators) and evaporator 16 (electrothermal tube) cool off cold water storage cistern 17 and boiler 13 earlier and heat, prepare into the cold water and the hot water of uniform temperature, and then indirectly inner core controlled temperature cabinet 24 and outer coil pipe controlled temperature cabinet 7 are carried out temperature adjustment with these hot water or cold waters, thermo-lag is little like this, and quick thermoregulation, temperature adjustment are accurate; The second, simultaneously inner core 4 and outer coil pipe 3 are carried out two temperature controls, reduce the influence of environment temperature and extraneous thermal source on the one hand, guarantee that on the other hand the external mutually coil pipe 3 of inner core 4 has a stable temperature difference test.
The utility model adopts outer coil pipe 3 structures to replace general calorimetric urceolus.Water constantly circulates in the coil pipe 3 outside, and recirculated water is pumped into continuously by outer coil pipe controlled temperature cabinet 7, and the heat that absorbs in the outer coil pipe 3 is pulled away the supreme lower leaf phenomenon of water temperature at once, thereby built an artificial environment that temperature is uniform and stable, also must improve the accuracy of instrument calorimetric.
The 5th pump 27, the 5th solenoid valve 25 and correspondent control circuits have been formed inner core cooling system (or claiming washing cylinder mechanism).
Calorimeter is inner core 4 and combustion container (oxygen bomb) in test, temperature all can raise along with the sample burning, the waste heat of test last time also can partly be retained in inner core 4 and the oxygen bomb member after test finished, when test is carried out continuously, these waste heats bring influence will for test next time, in order to eliminate the influence of testing waste heat last time as far as possible, and designed the inner core cooling system.Before each on-test, when the oxygen bomb inner core 4 of packing into, when closing the instrument loam cake, 27 of the 5th pumps are started working, from inner core controlled temperature cabinet 24, water pump is gone out, at this moment owing to often open the 5th solenoid valve 25 adhesive, closed the loop of leading to attached water case 21, water can only pump into inner core 4 through following automatically controlled cone valve 28 (at this moment being in opening state).The water that pumps in the inner core 4 cools off inner core 4 and oxygen bomb, water level controller was connected when water reached full, cut off the loop of the 5th pump 27 and the 5th solenoid valve 25, water then enters attached water case 21 from often driving the 5th solenoid valve 25, has so far finished the cooling operation of inner core 4 and oxygen bomb.
Outer coil pipe controlled temperature cabinet 24 and inner core controlled temperature cabinet 7 structures are to be provided with left fair water fin 29 and the right fair water fin 32 that staggers mutually in casing 30, are provided with stirring apparatus 31 at casing 30 middle parts, are provided with baffle 33 at the entrance point of casing 30.
The hot water of coil pipe controlled temperature cabinet 24 and inner core controlled temperature cabinet 7 or cold water are with backwater outside boiler 13 or cold water storage cistern 17 are delivered to, enter mixed pool from the mouth of pipe that mixes the pool, mixing pool stopping owing to baffle 33, the water of different temperatures mixes collision here, clamp-on stirring area through the slot of right fair water fin 32 then, in stirring area since the effect of left fair water fin 29 and right fair water fin 32 and stirring apparatus 31 do not stop stir, water here rotates, collides, mixes, reach even, enter the contributing region at last, emit from water delivering orifice.
Accelerate hot water or cold water's mixing through overmulling water, stirring, temperature has been reached rapidly evenly, thereby accelerated temperature adjustment speed, also improved the temperature adjustment quality.
