Mistakes screw chiller operation Misunderstanding screw chiller operation prone: Before power is not closed shell and tube condenser inlet valve, this will result in the phenomenon of channeling water. Part of the cooling backwater flow away from the shell and tube condenser Jiangning District of Nanjing accelerator freezer, thus reducing the cooling water flow shell and tube condenser, causing the unit condensing pressure rising, the host running the current increases, resulting in cooling capacity decline, but also a serious screw chillers stop working. In this way, the costs of electricity, so the cooling efficiency is reduced, equipment failure rate increases. Start from the wrong operation, the host of the cooling water outlet temperature and condensing pressure. The unit will alarm, the operator will cause wrong judgment, that the cooling water is not enough, so the condenser cooling water pump inlet valve and outlet valve to open big, and some will turn on the cooling tower fan, this will result in a cooling tower fan, and pump power increases, the cost will increase a lot. Some operators even open cooling water pump. To open the cooling water pump can reduce the condensing pressure and coolant temperature freezers, electric pump operation so wasted. Unit cooling water system is the correct method of operation: a, before starting the closed shell and tube condenser inlet valve Jiangning District of Nanjing extruder dedicated freezer units to prevent channeling of water. b, open the valve and out of the shell and tube condenser cooling water pump on, adjust the condenser inlet and outlet pressure. c, if the shell and tube condenser water inlet and outlet pressure gauge pointer swing is too large, then there is air in the cooling water system, you need to empty the gas within the unit, to be normal only after the pressure gauge. Plating chiller features: H, increase water filters, provides precision laser-quality work, increase the water pressure indicator, easy to adjust pressure and flow, increase with flow protection device, when the water flow is too low to automatically disconnect laser machine Jiangning District of Nanjing Hydraulic power system freezer to prevent overheating of the laser head due to lack of water, increasing electronic temperature control, double-digit display, a variety of settings and fault display just one button operation (open key), others are automatically from memory; I, cooling capacity ranges: 102500Kcal / h to 654800Kcal / h. J, the unit does not require cooling with water pumps, cooling towers and other auxiliary equipment, as long as ventilated convenience you can use, you can save a lot of material and installation costs, do not even need to set the room. K, in addition to styling products, the company also customized according to various types of special chillers and heat pump units, and provide on-site assembly, technical guidance and on-site commissioning service requirements. L, finned condenser unit, dual oil corrugated hydrophilic aluminum foil, the heat exchanger by a professional manufacturing and processing equipment, with a compact, small size, light weight, the advantages of high heat transfer efficiency, and low-speed configuration big leaf axial fans, can effectively reduce operating noise and reduce the impact on the surrounding environment.
