DLSB-5/20A New Low Temperature Coolant Circulating Pump
Date: 2021-08-12Read: 9
1、 DLSB-5/20A New Low Temperature Coolant Circulating Pump Whole Machine Solution
The entire device consists of a refrigeration system, a circulation system, and a control system.
1.1 refrigeration system
The refrigeration system consists of a compressor, condenser, evaporator, and capillary tube.
compressor:Piston compressor, small size, light weight, smooth operation, low noise, high reliability, high energy efficiency.
Condenser:adoptAir-cooled condenser,Internally, oxygen free copper threaded pipes are used for heat exchangeefficiencyHigh,Easy to clean and maintain.
Throttle mechanism: using capillary tube, stable and reliable performance.
Evaporator: Adopting304Stainless steel coil evaporator with high heat transfer efficiency; The evaporator is installed in the liquid storage tank, and it will not be damaged when the refrigerant freezes, making it safe and reliable.
1.2 circulatory system
Adopting low temperature resistanceStainless steel shielded pump is used to transport refrigerant, and the storage tank and circulation pipeline adopt304stainless steelThere is a safety label indicating the maximum liquid filling amount on the storage tank.
1.3 control system
Adopting LCD controller, fully digital Chinese display, temperature display accuracy0.1℃， 操作方便、安全、可靠，控制器符合CESecurity certification requirements.Communication adoptsRS485Interface, followingMODBUS RTUagreement.
