What do DANNICE tell you about the protective devices of screw chiller?
丹耐斯带您了解螺杆冷水机的保护装置有哪些？为了更好的解答疑惑，将把所有的配置解答清楚，方便您的购买使用。
DANNICE take you to know what are the protective devices of screw chiller? In order to better answer doubts, all configurations will be answered clearly to facilitate your purchase and use.
首先，我们要了解什么是螺杆式冷水机，螺杆式冷水机是以各种形式的螺杆压缩机为主机的冷水机组。它是由螺杆式制冷压缩机、冷凝器、蒸发器、热力膨胀阀、油分离器以及自控元件和仪表等组成的组装式制冷装置。
First of all, we need to understand what is a screw chiller, screw chiller is a chiller with various forms of screw compressors as the host. It is a packaged refrigeration device composed of screw refrigeration compressor, condenser, evaporator, thermal expansion valve, oil separator and automatic control components and instruments.
其次，我们要了解螺杆式冷水机的配置构造，螺杆式冷水机在我国制冷空调领域内得到越来越广泛的应用，螺杆式冷水机是由螺杆式制冷压缩机、冷凝器、蒸发器、热力膨胀阀、油分离器以及自控元件和仪表等组成的组装式制冷装置。按照冷却方式，可分为水冷式冷水机和风冷式冷水机；按照用途，可分为热泵式机和单冷式机；按照组装的压缩机台数，可分为单机头和多机头冷水机。
Secondly, we need to understand the configuration and structure of screw chiller, screw chiller has been more and more widely used in the field of refrigeration and air conditioning in our country, screw chiller is composed of screw refrigeration compressor, condenser, evaporator, thermal expansion valve, oil separator and automatic control components and instruments, etc. According to the cooling method, it can be divided into water-cooled chiller and air-cooled chiller; According to the use, can be divided into heat pump machine and single cooling machine; According to the number of assembled compressors, it can be divided into single head and multi-head chiller.
丹耐斯对您解答螺杆式冷水机的保护装置包括：
1. 温度控制开关：用于控制冷水机的运行温度。
2. 防冻开关：防止系统内部冻结。
3. 断流开关：在发生异常时切断电源，防止设备损坏。
4. 可熔栓：在电流过大时熔断，保护设备不受损坏。
5. 高低压压力开关：控制系统的压力，防止压力过高或过低。
6. 过载保护器：防止电机过载。
7. 压缩机过热保护器：防止压缩机过热。
8. 压缩机频繁启动保护器：防止压缩机频繁启动，减少设备磨损。
9. 异常指示灯：显示设备异常状态。
10. 防爆装置：在某些型号的冷水机中，用于防止爆炸。
11. 油压差保护：用于带油泵的压缩机，防止油泵影响压缩机的平稳性，造成气缸卸荷机构不能正常工作。
12. 压缩机排气温度和油温保护：用于防止排气温度过高和油量过低或过高。
13. 冷却水套断电保护：用于氨压缩机气缸盖装有冷却水套，对压缩过程进行外部冷却。
DANNICE protection devices for your answer screw chiller include:
1. Temperature control switch: used to control the operating temperature of the chiller.
2. Antifreeze switch: prevent the system from freezing inside.
3. Cut-off switch: When an exception occurs, the power supply is cut off to prevent device damage.
4. Fusible plug: fuses when the current is too large to protect the equipment from damage.
5.High and low pressure switch: control the pressure of the system to prevent the pressure from being too high or too low.
6. Overload protector: prevent motor overload.
7. Compressor overheat protector: prevents the compressor from overheating.
8. Compressor frequent start protector: Prevent the compressor from frequent start and reduce equipment wear.
9. Abnormal indicator: indicates the abnormal status of the device.
10. Explosion-proof device: In some models of chiller, it is used to prevent explosion.
11. Oil pressure differential protection: used for the compressor with oil pump to prevent the oil pump from affecting the stability of the compressor, causing the cylinder unloading mechanism to not work normally.
12 compressor exhaust temperature and oil temperature protection: used to prevent the exhaust temperature is too high and the amount of oil is too low or too high.
13. Cooling water jacket power off protection: used for ammonia compressor cylinder head with cooling water jacket, external cooling of the compression process.
对于螺杆式冷水机的保护装置，我们了解过后得到的认识方面更清晰了，在了解螺杆式冷水机的保护装置后，我们可以更放心更方便的沟通对于机械的设备情况，也更熟悉机械的构造。对机械的价格也会多少有点概念和想法。丹耐斯对此的解答希望给您带来愉快的阅读，谢谢。
For the protection device of screw chiller, after we understand the understanding of the clearer, after understanding the protection device of screw chiller, we can more assured and convenient communication for the mechanical equipment, but also more familiar with the mechanical structure. There will also be some concepts and ideas about the price of machinery. DANNICEanswer to this question will give you a pleasant reading, thank you.
