I. Working principle The SDAC6000/SDAC6000u bomb calorimeter adapted the principle of constant temperature oxygen bomb calorimeter, features the jacket water temperature keeping constant and judges the finishing of the test by the bucket temperature changes. Then correct the heat exchange between the bucket and jacket by the cooling correction formula. Semi-conductor chilling is used to cool water tank, which can solve the problem of temperature instability for the bucket when software temperature controlling point changing automatically due to high ambient temperature or raised tank water...

I. Working principle The main principle is: weighing some weight of the sample, place it into the bomb, and fill sufficient oxygen into the bomb, and place the bomb into a bucket with some volume of water, burn the sample completely in the bomb and the heat released by the sample are absorbed by the water around the bomb. Calculate the raised water temperature. When the jacket water temperature is constant, the heat capacity of the absorbing water and other parts in the water is constant. The calorific value can be calculated by the raised water temperature.

II. Main Frame Structure SDC calorimeter main frame is composed of bucket, jacket, pump, heating parts, solenoid valve, temperature testing parts, heating parts and other controlling and protecting parts Automatic device Jacket bucket

Brief introduction of the internal parts: 1.Frame and shell: Frame and carrier of all spare parts inside the instrument, which structures the instrument appearance. 2.Bucket: Used to contain test water whose volume has been determined by the water level probe. 3.Jacket: Provide a stable environment for the bucket, to avoid the influence of the ambient temperature. The spray stirring way makes sure the outer jacket water temperature controllable and uniform. 4.Pump: is used for whole water circuit system, providing power for water feeding and draining. 5.Solenoid valve: Control water flow...

Sundy Thermostatic water tank: Thermostatic water tank is mainly composed of Semiconductor cooling film, water-storage tank, pump. 1 .Shell: It’ s the frame of all spare parts inside thermostatic water tank, which structures the instrument appearance with shell. 2.Water-storage tank: Capacity 14L, storing test water for the instrument, equipped with water volume judging device. 3.Semiconductor cooling film: Cooling test water to reach the required test temperature when the temperature is too high.

III. Installation requirements Environmental Requirements •Temperature: 15 ~ 30°C Humidity: <85% • Keep the lab tidy, and with no smoke or dust (esp. coal smoke dust); •The environment should be stable, with low cross-ventilation, and with no strong magnetic field, vibration sources or corrosive gases; • Keep the instrument from sunshine; •Working Power: Instrument: AC220V ± 22V, 50HZ± 1Hz, max power 0.75kW; knife switch or air switch is required, and spilt-phased with other high power instruments; Reliable ground wire table-board: recommend size LXwXH 2X0.8X0.8m, Main body size:...

Prepare about 30 Kg (for one water tank)distilled water or deionizer water. Prepare oxygen bottle. Oxygen purity and the oxygen pressure inside the bottle should conform to the standard(purity >99.5%,cannot use electrolytic oxygen). Prepare 500ml beaker or counting cup 1 pcs，10ml counting cup 1pcs, water pail 1pcs for check oxygen bomb gas tightness. Prepare analysis balance with sensitivity no lower-than 0.1 mg, and associated drying utensils. Prepare nippers, scissors, spanners, screw-drivers, pincers, angle spoons and other bas

IV. Installation & Debugging Unpack: a.open packing boxes carefully, do not be hurt and do not damage the instrument or spare parts.，Check the spare parts with customer following the packing list. b.Typical Layout：Place computer (principal machine, monitor and keyboard) in the middle and with printer and SDAC6000 calorimeter on their left and right side for convenient operation

c. Please note to keep the distance to be 80mm or more between the instrument back plate and the wall. On the left and right sides to keep a distance of 80 mm or more in order to reserve the space for maintenance and inspection. d. Take down plastic film and the front cover. e. Check the tubes and cables inside to avoid loosening during transport.

Install: a.Connection between the main frame back coverand thermostatic water tank:Take fast plugs 、10*6.5 PU tubes and power cable from spare part box, insert fast Plug onto the main frame back cover and thermostatic water tank back cover, connect the fast plug by PU tubes(“inflow” to “inflow”,”outflow” to “outflow”,should cut pu tube smoothly to avoid water leakage) ,then connect power calbel for thermostatic water tank from main frame back cov

b. Connection of oxygen gas bottle 1. open oxygen bottle for releasing a little gas ,2 seconds later, close it; 2. connect oxygen pressure regulator with oxygen bottle 3. connect main frame with oxygen pressure regulator by oxygen tube and lock nut,make sure no oil or something combustable into gas tube. 4. open oxygen bottle, adjust oxygen pressure regulator until low pressure between 2.8—3.0 MPa 5. check gas leakage at all connection points.

c. Connection between pc and instrument. 1. Take network cable form spare parts box and use it to connect instrument and pc network interface. 2. take download cable form spare parts box and use it to connect instrument download interface and pc com interface(when need to download,install a screw at the yellow marked hole,after download hex file,take screw out).

d. Add water: open thermostatic water tank cover, add distilled water or deionizer water into thermostatic water tank slowly until near the Maximum water level mark. e. set thermostatic water tank temperature same as room temperaute(not higher than 30 ℃,click left and right button at same time for 5 seconds,then the temperautre will flash,use left button to set temperautre higher,use right button to set temperautre lower.when finish setting,just leave it,system will save setted temperature automaticly).
