Protection methods for winter instruments

    I. Selection measures    Choose instrument with insulation device. First, according to the category and use of the meter and the geographical location of the installation, the insulation and antifreeze requirements of the meter are proposed, and then coordinated with the manufacturer. 多度,如果单从选型上解决,那么性价比相当大,因此不合算。 For example, in some places in the north, the temperature difference between day and night is relatively large, and it can reach more than 20 degrees below zero at night. If the solution is based on selection alone, the cost performance is quite large, so it is not cost-effective.

  Second, insulation measures     Insulation material is used for insulation, which means that the instrument is easy to freeze or is afraid of freezing. When winter is approaching, regular inspections and frequent drainage are required to prevent damage to the packaging insulation material.

  Third, heat tracing measures

   、蒸汽伴热措施也就是使用管蒸汽暖气保温。 1. The steam tracing measure is to use pipe steam heating for heat preservation. Before the winter arrives, check whether the steam insulation pipeline is open or blocked.

   、保温保护箱措施 2.Insulation protection box measures

   、电加热带措施 3 , electric heating belt measures    Electric heat tracing technology is a new type of technology. It is a heating technology that directly converts electrical energy into thermal energy. 但是使用的时候要注意所用伴热带的长度,要经济适度)You need to install insulation cables first, and wind the heating cable around the insulation instrument, or stick it inside the instrument cabinet ( but pay attention to the length of the heating cable used when using it, and it should be economical and moderate ) .

  Fourth, maintenance measures

  、安装 1.Installation   Reasonably choose the installation location: such as a dry place without rain or snow dripping.

  、点检 2 , check   When conditions permit, a person will perform technical confirmation and technical disposal daily, for example, to see if the insulation material is damaged or whether the steam pipeline is blocked.

  、报警 3.Alarm   Conditionally, a sound and light alarm small device can be installed in the state of steam leakage or power outage, in order to facilitate the discovery and timely rectification of hidden dangers of heat preservation and antifreeze measures.

  、巡检 4 , inspection   The responsible person of the regional instrument maintenance shall carry out regular inspections according to the scheduled inspection route. During the inspection, it is required to check whether the insulation pipeline valve is normal, whether the insulation box is normal, whether the drainage device is normal, whether the insulation material packaging is intact, and whether the electric heating and power supply components are normal.
