Henan mine cable load constant day burning tester signed success - order no. 20120612001
End customer request KP8027 coal burning with cable load testing machine production of technical indicators:
A, scope of application:
Flame retardant cable applies to MT818-2009 test on flame retardant, flame retardant cable joint.
Second, conform to the standard:
According to the corresponding requirements of MT386-1995 coal industry standard design and manufacture.
Three, the main parameter
1, the burning body:
Case size: always W500 L1000 * * H1300mm
Combustion box size: W500 L1100 * * H900mm,
Case is made of the numerical control machine tool processing forming, circular modelling beautiful generous. High quality SUS304 stainless material, has the characteristics of beautiful, rust corrosion.
Box at the top of the strong downdraft exhaust system, the test is completed, will waste gas discharge outside; During the trial, this is a closed system.
On both sides from the enclosure in the bottom 310 mm open mouth, a 120 mm is used to pick up sample load.
Enclosure front in the process of the test can be sealed toughened glass observation window, convenient for observation test.
2, combustion burner:
The material of our company independent research and development of H62 brass burner, fully meet the requirements of MT386-1995.
The standard power: 500 w.
The crater diameter: ￠0.90 + / - 0.03 mm, nozzle lamp length: 1.60 + / - 0.05 mm, nozzle distance air inlet height is 102 mm, flame tube ￠9.5 mm inner diameter.
Torch Angle: 90 ° vertically (longitudinal axis in a vertical plane and vertical direction of 90 ° Angle), can be adjusted, the air inlet, inner flame of 70 ~ 80 mm, outer flame of 115 ~ 135 mm, is adjustable.
3, gas:
Methane/gas (purity over 98%, by the supplier with certificate), the calorific value of 998 btu (British thermal unit)/cubic feet. Per cubic meter of 37.1 million joules. (the user should bring along their own)
4, temperature measuring system:
Imported K type thermocouple, do coat with 1.0 mm diameter stainless steel pipe.
Intelligent PID temperature control table and match the K type thermocouple. The reading of 0 ~ 999.9 ℃.
5, load current:
10 ~ 3000 a continuously adjustable.
6, the main fixture:
Test stand: a total of 4 groups, by the high quality of 304 stainless steel stents and burner and observation window plane parallel to the plane for observation.
Equipped with flame can be measured when the scale of inner and outer flame.
7, standard sample specifications:
L, 1800 mm or more
8, combustion system:
Relay and cylinder temperature control, the combustion process is automatic, can burn in time in the specified temperature range. With a comparison with the conventional manual operation, the test results more accurate and simple operation.
Cylinder: 0 ~ 100 mm.
Air filter: 0 ~ 10 kg can be adjusted continuously. USES the high quality filter, can discharge the moisture in the air is completely, can effectively improve the service life of the cylinder.
9, the operating system:
Burning time relay control system, automatic recording, combustion duration.
Combustion timing: when the temperature of the sample temperature reaches 204 ℃, the burning torch will automatically move to the surface of specimen under, began to burn. Automatic recording burning time (according to the rules set: such as the burning of 1 min), when the set time arrives, the burner automatically return to its original position.
The burning time: when the combustion time arrival, the timer automatic timing; If within the prescribed time (such as: stop for fire 4 min), the process, if the sample is burning flame, by the operator press the stop button to stop time, recording time, such as within the prescribed time, then determine the sample through the check.
Burning the timer range: 0 ~ 99.99 S/m/h.
A burning timer range: 0 ~ 99.99 S/m/h.
10, ignition mode:
High voltage electronic ignition, convenient and stable.
11, working voltage: AC 220 v, 50 hz
