反应釜冷水机组怎么配置和选择

时间:2017-10-24作者:舜甫科技 点击:
  反应釜冷水机组为一体箱式冷水机组,由冷凝器、循环泵、膨胀阀、水流关断、内部冷水箱及温度控制系统组成,并且均置于冷水机组机架中,其作用是对反应釜夹套进行冷却降温以达到生产工艺的要求.反应釜冷水机组根据工艺的不同分为常温型冷水机和低温型冷水机,根据制冷量大小又被分为涡旋式冷水机和螺杆式冷水机两大类型.
 
  反应釜冷水机组选择需要注意的事项最主要是要与生产工艺相契合,应根据生产工艺的实际需求来进行选择。

一、反应釜冷水机选择时需要参考的参数:
 
  1、反应釜的大小和重量
 
  2、反应釜夹套或盘管的容积和物料的参数,密度,比热,粘度等
 
  3、物料所需要达到的温度,进出口是多大.
 
二、反应釜冷水机组设有多项安全保护装置,其中以下是反应釜冷水机组标准配置:
 
  1、高低压力保护:确保制冷系统在工况超出机组使用范围时实现自动保护;
 
  2、电源保护:缺相保护、逆相保护、欠电压保护、过载保护、马达过热保护;
 
  3、防冻保护:在冷冻水温度过低时,机组自动停机;
 
  4、水流保护:当系统水流停止或水流量过小,机组自动停机;
 
  5、过载保护:当压缩机、水泵出现过载,机组制动停止并报警。
 
三、除了以上配置外,客户还可以按照需求选择以下反应釜冷水机组配置:
 
  1、3P以上压缩机
 
  2、全系列均配置304不锈钢膨胀水箱
 
  3、微电脑控制器运行系统
 
  4、采用进口电器组件
 
  5、高低压带油压力表,
 
  6、热力膨胀阀、干燥过滤器组件
 
  7、翅片式(风冷式冷水机)冷凝器,壳管式(水冷式冷水机)冷凝器,盘管式(车间换热设备密闭型用)或管壳式(车间换热设备敞开型用)蒸发器
 
  8、不锈钢低温循环泵.
 
  9、温度过低,防结冰保护装置
 
  10、静电喷塑外壳,欧化设计,美观大方,外表板采用快速拆装形式,方便使用和维护.
 
  The reactor water chiller as one box type water chiller, condenser, a circulating pump, expansion valve, water shutoff, internal cooling water tank and temperature control systems, and are placed in the chiller rack, the effect of reactor jacket cooling to achieve the production process requirements. According to the reactor water chiller different processes for normal temperature and low temperature type cold water machine, cold water machine, according to the refrigeration capacity can be divided into scroll chiller and screw chiller two types.
 
  Reactor water chiller selection need to pay attention to the main is to fit in with the production process, should be selected according to the actual needs of the production process, the need to refer to the following parameters is the reactor cooling water machine selection:
 
  1. the size and weight of the reactor
 
  2. the volume and material parameters, density, specific heat, viscosity, etc. of the reactor jacket or coil
 
  3. the material required to reach the temperature, import and export is how big
 
  The reactor water chiller has a number of safety protection devices, and the following is the standard configuration of the reactor water chiller:
 
  1. high and low pressure protection: to ensure the refrigeration system in the operating conditions beyond the scope of use of the unit to achieve automatic protection;
 
  2. power supply protection: lack of phase protection, reverse phase protection, under voltage protection, overload protection, motor overheating protection;
 
  3. antifreeze protection: when the freezing water temperature is too low, the automatic shutdown of the unit;
 
  4. water protection: when the system flow stopped or water flow is too small, the unit automatically shut down;
 
  5. Overload protection: when the compressor and pump are overloaded, the brake stops and alarms.
 
  In addition to the above configuration, the customer can also select the following reactor cooling water chiller configuration according to the requirements:
 
  1. Compressor above 3P
 
  2. the whole series are equipped with 304 stainless steel expansion tank
 
  3. microcomputer controller operation system
 
  4. Using imported electrical components
 
  5. high and low pressure oil pressure gauge,
 
  6. Thermal expansion valve and dry filter assembly
 
  7. fin type (air-cooled chiller) condenser, shell and tube type (water-cooled chiller) condenser, coil type (workshop heat exchanger closed type) or shell and tube type (workshop heat exchange equipment open type) evaporator
 
  8. Stainless steel low temperature circulating pump
 
  9. the temperature is too low, anti icing protection device
 
  10. static plastic shell, European design, beautiful appearance, the appearance of plate with fast disassembly, convenient use and maintenance.
