三、产品特点:

★高效节能。冷冻A低温度可达-40℃;制冷速度快,30-50分钟可达 -30℃— -40℃;

★全部采用数字化仪表显示,实现自动计时、控温、计次,试验结束自动停机。

★节约人力,而且使试验更科学,周期更短,数据更准确。试验时只要把试件放入冻融箱内,设定好试验参数,气冻水融即在同一箱内完成,整个试验过程无须人看管,仪表对每个循环次数进行记录,达到设定循环次数后,整机自动停止运行,并告之用户。

Product features of concrete freeze-thaw test chamber:

★ High efficiency and energy saving. Freezing A low temperature can reach -40 ° C; fast cooling speed, 30-50 minutes can reach -30 ° C--40 ° C;

★ All digital display is used to realize automatic timing, temperature control and counting, and automatic shutdown after the test.

★ Save manpower, make the experiment more scientific, the cycle is shorter, and the data is more accurate. During the test, just put the test piece in the freeze-thaw box and set the test parameters. The air-freeze water thawing is completed in the same box. The entire test process does not need to be watched by the instrument. After the number of times, the whole machine automatically stops running and informs the user.

五、操作规程:

★开机前检查机组是否出现凹凸异状,电源连接是否妥当,并加足够的防冻液,不得在无防冻液的状态下开启机器。

★机组系统操作。开机后,观察高低压表的指数来判定机组是否运行正常,一般压缩机正常运行时,高压压力为14-22kg/cm3,低压压力为0.8-1.5kg/cm3。

★ 机组保养。要保持机房清洁及通风良好,定期进行冷凝器的清洗除污工作,保证机组正常稳定工作。如机组停用一段时间,因防冻液介质污积物沉积,容易造成循环泵泵叶蓓污积物凝固,在开机时必须先转松循环泵转子,以防避免泵叶不运转,导致循环泵烧毁。

★ 工作结束后,切断电源,保持整洁并作好仪器使用记录

Fifth, the operating rules of concrete freeze-thaw test box:

★ Before starting, check whether the unit has irregularities, whether the power supply is properly connected, and add enough antifreeze. Do not turn on the machine without antifreeze.

★ Unit system operation. After starting up, observe the index of the high and low pressure meters to determine whether the unit is operating normally. When the compressor is normally running, the high pressure is 14-22kg / cm3, and the low pressure is 0.8-1.5kg / cm3.

★ Unit maintenance. It is necessary to keep the equipment room clean and well ventilated, and regularly perform cleaning and decontamination of the condenser to ensure the normal and stable operation of the unit. If the unit is out of service for a period of time, the dirt on the anti-freezing fluid will easily cause the solidification of the dirt on the circulating pump pump leaves. When turning on the machine, the rotor of the circulating pump must be loosened to prevent the pump from not running, which will cause the circulating pump. burn.

★ After the work is completed, cut off the power, keep it tidy and make a record of the use of the instrument
