Concrete fast freeze-thaw testing machine (10-piece)
KDR-V3
The device is applicable to the relative durability index of the box with dynamic modulus and weight loss
Freezing resistance test of concrete as an evaluation index. That is, in order to determine the resistance of concrete under the repeated action of water and negative temperature, to determine the concrete anti-freezing label for the purpose of professional rapid freeze-thaw test. The equipment adopts the water freeze-thaw method, the standard concrete specimen is placed in the rubber cylinder to soak in water, and then the rubber containing the specimen and water is arranged in the test mold box, and the water layer around the specimen is frozen and melted periodically with the refrigerant as the circulating medium.
The equipment adopts a box (groove) external circulation mode, freeze-thaw equipment box is made of high-grade stainless steel material, automatic control system is controlled by industrial computer, high degree of automation. The whole device has the characteristics of compact rhythm, small floor area, simple installation and operation, convenient maintenance, reliable operation and energy saving, etc. It is an ideal test equipment for concrete fast anti-freezing test.
Main technical indicators and parameters:
1. Specimen size: 100*100*400
2, the thickness of the water layer around the specimen: 3mm
3, at the end of the freezing and melting time, the center temperature of the specimen:
(1) The center temperature of the specimen at the end of freezing: -17ºC
(2) The center temperature of the specimen at the end of dissolution: +8.0ºC
You can also change the set values of the six set points on the medium length chart recorder by pressing
The center temperature of the specimen and the temperature of the freeze-thaw cycle medium required by the user are set
Agreed. The temperature control accuracy is ±1.0ºC.
4, freeze-thaw cycle: the freeze-thaw cycle lasts 2-4 hours, and the samples used for melting are less than 1/4 of the whole freeze-thaw cycle.
5, the time component capacity is 10, 16, 28, one of which is the central temperature measurement specimen.
6. 3 groups of dimensions: length 1320mm, width 860mm, height 910mm
7. 5 groups of dimensions: length 2003mm, width 830mm, height 900mm
8, 9 group inner machine size; Length 970mm, width 920mm, height 910mm
9 groups of external machine size 1215mm, width 750mm, height 880mm
9, weight: Unit: 200 kg, 300 kg, 500 kg
The main functions of the system include: sample center temperature circulating liquid temperature display record: freeze-thaw process conversion and circulating liquid temperature control: freeze-thaw cycle number control and cycle end index and temperature control: compressor exhaust pressure, suction pressure and electric unit temperature rise protection: circulating liquid flow protection and overtemperature protection: Motor overload protection, such as power failure and water failure and other abnormal conditions, the machine can automatically stop running. The whole freeze-thaw 3 process is completely automatic, in case of failure, it will give sound and light alarm, and take protection by itself.
10, unit power supply: three-phase four-wire system 380V, 50HZ
11, the maximum operating power of the unit: 11.1W
Among them: brake compressor 3.0W, 5.0KW
Electric heater 9.0KW
Freezing circulation pump 2.2KW dissolving circulation pump 1.1KW
12, freeze-thaw cycle medium: -35.0ºC military antifreeze, charge capacity 160 kg.
