Forced stirring convection is used in the high and low temperature liquid tank. The automatic up, down, left and right displacement mechanism is used to move the sample basket to the preheating and precooling tanks, and the reciprocating impact mode. Fluorine oil uses a single identical liquid in the high and low...
1) The shape is elegant and generous, and the agile combination can be used to implement standards; 2) Touching the rainwater, some of the imported stainless steel is mainly used to prevent rust; 3) Imported motor drive pendulum, high reliability, adjustable water flow and rotating viewpoint; 4)...
The clean air delivery rate (CADR) of the purifier environmental test chamber is calculated as: CADR=V(ke-kn) In the formula: CADR - clean air volume, m3 / min; V—test chamber volume, m3; Ke—total decay constant, min-1; Kn - natural decay constant, min-1. DONGGUAN HUANYI...
1) Purifier environmental test chamber sampling port adopts four-tube dual-channel mode, made of stainless steel, with inlet and return ports to avoid negative pressure caused by pressure changes, resulting in cabin leakage; 2) Double-channel stainless steel sampling tube and PTFE sampling tube are installed...
1) Purifier environmental test chamber cleaning method is different from the traditional method. The traditional cabin method is to pump 95% of the gas in the tank first, and then re-inject clean air to the maximum volume; 2) Repeat the above process for at least 6 times to check whether there are any...
1. The front air purification device adopts the series absorption method to purify the humidity, formaldehyde and other volatile substances in the air. 2. The absorption tube is filled with an appropriate amount of granular activated carbon and color-changing silica gel. The activated carbon filling amount is...
1. The most direct test for air tightness is the compression test or the pressure test. The air leakage should be less than 0.9m3/h; 2. In addition, the flow meter can be connected to the air inlet and outlet of the test chamber, and the door can be closed while measuring the outlet and inlet air flow. Under...
1. The control panel of the equipment shows temperature, humidity, time, flow and pressure. It can be monitored in real time. 2. The pipeline has good thermal insulation protection. 3. The filtered air treatment agent used for clean air is easy to replace. 4. The inner wall of the box is mirror stainless...
1. Salt solution: 1 salt is high quality sodium chloride, sodium iodide content <0.1% when dry, impurities <0.3% 2 salt solution concentration (5 ± 1)% (mass ratio) 3 solution method is made of brightener, and the salt solution of (5±1) parts by mass is dissolved in distilled water or deionized water...
1. Keep the tensile testing machine clean; 2. Before working on the tensile testing machine, check the reducer under the workbench for lubrication. 3. The lead screw and silk nut of the testing machine are added once every six months; 4. Carefully connect the wiring of the sensor; 5. The pre-tightening...
1. Place the test sample on the trolley (horizontal impact tester and bevel impact tester) or platen (hanging impact tester) in a predetermined state. 2. When testing with a horizontal impact tester, the trolley is moved along the rail at a predetermined speed and reaches the required impact velocity upon reaching...
1. Check if there is enough water in the water tank before running. If it is not, please fill it first (you must add clean tap water) to avoid damage to the water pump; 2. If you hear an abnormal sound during operation, please stop the machine and check it again before restarting it, so as not to affect the...
