Standards
AQ 6103-2007, GB/T 17599, GB/T 8965.2-2009, ISO 9150, EN 348
Feature
1. Generate metal drop device:
1.1 Oxyacetylene torch melting metal wire (stick) one end, welding tip caliber (1.2±0.1)mm;
1.2 The movement of metal wire (stick) control by wheel system motor speed regulation, motor wire feed rate(10±1)g/min;
1.3Welding nozzle center vertical with wire (stick), the distance between welding tip and wire(stick) adjustable, usually its 12mm;
1.4 Droplet weight (0.50±0.05)g;
1.5 Generate droplet frequency 20 drops/(min±3s);
1.6 Start distance from wire to welding burner;
1.7 Length of welding torch deep blue flame core;
2. Droplet guide mechanism:
2.1 Funnel guide: the angel between guidance axis and vertical adjustable, caliber can through diameter (8±0.2)mm metal strip, add lid on guide slot for it can cover when it not using.
2.2 Holder: bearing and funnel guide, its three dimensional adjustable.
3. Temperature sensing system:
3.1 Sensor support: refractory insulation material, pyroconductivity is (0.125±0.015）W/（m.K), specific heat 1.15J/ (g.K) groove dimension of surface (13.5×11) mm while 40℃.
3.2 Temperature sensing system: armoured platinum resistor, coating high temperature adhesive, resistance100Ω, Clitheriform, dimension (12.5×10) mm, thermal response time≤0.5s while 0℃.
3.3 Record display: can display warming and its corresponding droplet no. time, frequency value on sample back; Guide slot test temperature>250℃, temperature rise on sample back≥40K will alert.
3.4 Precision: resolution ratio≤±0.5K, deviation between temperature display and alert function test ≤±0.4K.
3.5 Structure and install: temperature sensor can contact by groove center nearby two hole's guide line, four sides bolt can fix sensor support on sample frame.
4. Sample frame:
4.1 Sample holder support can guarantee sample cling to sensor;
4.2 Put（175±5）g pre-tension on sample;
4.3 The location of sample on vertical and horizontal direction adjustable.
Instrument is equipped with professional computer software.
Oxygen and acetylene gas need to purchase on your local by yourself.
