The outstanding feature of the refrigeration cycle is that heat is removed from the object below the temperature of the ambient medium and transferred to the environmental medium. This transfer process is usually carried out by a screw chiller, and the refrigeration compressor is a screw chiller. The most important component.
Screw chiller working principle technical knowledge|Shenzhen screw chiller factory price- Dongyuejin brand screw chiller refrigeration compressor composition analysis: The outstanding feature of the refrigeration cycle is to take heat from objects below the ambient temperature, and Transfer to the environmental medium to complete this transfer process, usually using a screw chiller, and the refrigeration compressor is the most important part of the screw chiller.
First, we will learn more about the composition of the Dongyuejin brand screw chiller. It is mainly composed of four basic parts: a screw refrigeration compressor, a condenser, a throttle valve and an evaporator, and is connected together by a pipeline to form a sealed refrigeration system. This section describes the composition of a single-stage screw chiller, which includes a single-stage refrigeration compressor, oil circuit system (including oil separator, oil cooler, oil pump, oil filter, oil pressure regulating valve and pipeline), pneumatic system (including suction filter, suction shut-off valve, suction check valve and exhaust check valve), as well as the machine side console.
Secondly, the working principle of the screw chiller refrigeration compressor is known. Similar to the piston refrigeration compressor, it also reduces the gas density of the unit volume by increasing the volume of the gas after entering the machine, so that the pressure of the gas state refrigerant increases.
In the body of the screw chiller refrigeration compressor, there is a figure-shaped inner cavity in which two mutually engaged rotors (male rotor and female rotor) are installed. When the two rotors rotate, the teeth of the two rotors are inserted into each other. As the insertion length of the rotor becomes larger and larger in the tooth groove, the volume of the gas groove becomes smaller and smaller, thereby achieving the purpose of compressing the gas refrigerant.
Third, the oil circuit system of the screw chiller refrigeration compressor. The Dongyuejin brand screw chiller is equipped with an oil-injected screw refrigeration compressor. The amount of lubricant injected into the compressor is about 0.5%-1% of the theoretical displacement of the compressor. The lubricating oil is cooled and cooled in the unit. , sealing and noise reduction. The screw refrigeration compressor oil circuit system is composed of an oil separator, an oil cooler, an oil pump, an oil filter, a hydraulic pressure regulating valve, and the like, and is connected by a pipeline.
The power of the Dongyuejin brand screw chiller is generally large, and it is mostly used in large-scale occasions where the chiller power is high, such as ink printing factory, chemical plant, battery factory, food preservation plant and central air conditioning centralized system. Adjust, when the temperature reaches the set temperature, the compressor stops working. When the temperature is higher than the set temperature, the compressor starts up by itself, saving energy and saving electricity.
