The structure of the low-temperature constant temperature water tank
1, it shell metal plate, the control box is installed directly on the water tank. Next to the condensate pipe in and out of the water faucet two, the water tank using imported water pumps as a circulating power to solve the drawbacks of uneven temperature and water, so that the instrument's temperature control accuracy and the uniformity of the water can reach a high level of requirements. Some cryostat sink products can be inside and outside the cycle, with the latex tube will be two inlet and outlet pipe connected can be used for internal circulation, remove the latex tube will be two water pipes were connected to the kettle inlet and outlet can be formed outside the cycle, close to the control panel of a copper water pipe connected to the pump on the outlet pipe, the other is the inlet pipe, connecting the attention of not connecting the wrong way, so as not to start when the water will flow backward.
Cryostat sink parts and principles
1, sink parts: compressor, condenser, evaporator, fan (internal and external) circulating water pump, stainless steel liner, heating tube, intelligent temperature control table.
2, the sink principle: compressor operation after suction, compression, exhaust, condensation, throttling, and then low-temperature evaporation of heat absorption vaporization, so that the water temperature down to the temperature set by the temperature control table, such as the temperature control table set temperature is higher than room temperature. Temperature control table in the contactor automatically work to give the heating tube current signal, the heating tube began to work. In the cryostat tank work, you can use the machine's inlet and outlet to do the machine water supply inside or outside the cycle, but also the machine water outside the lead, in the cryostat tank outside the body to do the second thermostat field.
3, the compressor as an important part of the thermostatic tank, its working principle is mainly based on the physics of the relationship between pressure, volume and temperature: when the quality of the gas is a certain amount of time, the product of pressure and volume is a constant. Therefore, to realize the unit mass of gas pressure doubled, it is necessary to make its volume reduced by half, the cryostat sink compressor is based on this principle of gas compression. Generally speaking, the realization of the physical mode of gas compression are as follows: relative static gas compression volume change and flow gas diameter change, relative static gas volume change, such as live race compressor, rolling rotor compressor, screw compressor, etc.; flow gas diameter change, such as scroll compressor, jet compressor.
Low-temperature constant-temperature water tank use
Use 220V AC power supply, power socket rated current is not less than 10A, and has a safety grounding device, add water from the water from the upper cover plate is not less than 8cm, you must use soft water, distilled water, do not use well water, water, spring water and other hard water to prevent the heating tube cracking and the impact of the thermostat sensitivity. Set the required temperature value is, first of all, open the power supply, set the required temperature value on the instrument according to the instructions, the temperature reaches the set temperature, you can open the cycle switch, so that the program enters the normal working state.
The above is for you is about the structure of the cryostat sink cryostat sink method of use of the relevant content, I hope to be able to bring help to friends in need.
