Hitachi heat pump compressor
Does the compressor not start related to the four-way valve? There is no relationship between the compressor does not start and the four-way valve. Therefore, when the four-way valve coil is damaged, it will not cause the air-conditioning compressor to fail to start normally, nor will the compressor start normally after the good four-way valve coil is replaced.
compressor When the compressor does not start, it is recommended to first check and confirm the resistance value of the air conditioning compressor winding and the state of the compressor starter, and then check whether there are obvious abnormal conditions in the main electrical control components of the air conditioner. Don't worry about the four-way valve again.
compressor Introduction of working principle, characteristics, advantages and disadvantages of scroll compressor Scroll compressors are not often heard by many people. After all, many people are not of industrial origin, and it is a matter of course that they do not know much about scroll compressors. In order to make everyone better understand scroll compressors, Hitachi heat pump heat source compressors, okmarts.com editors will introduce scroll compressors; analysis of scroll compressor operation principles; scroll compressor characteristics; scroll compression The advantages and disadvantages of the machine are described in detail.
First, the scroll compressor is introduced. Scroll compressor belongs to a type of volumetric compression compressor. Hitachi heat pump compressor, movable scroll and static scroll constitute a compression component. Secondly, the working principle of the scroll compressor. The scroll compressor is formed by two scrolls interlocking with the dynamic and static forms of the double function equation line. During the operation of suction, compression, and exhaust, the static plate is fixed on the frame. The moving plate is driven by the eccentric shaft and controlled by the anti-rotation mechanism. It rotates around the base circle of the static plate and makes a plane with a small radius. The gas is sucked into the periphery of the static disk through the air filter. With the rotation of the eccentric shaft, the gas is gradually compressed in the crescent-shaped compression cavity formed by the dynamic and static disk occlusion, and then continuously sent by the axial hole of the static disk component. Again, scroll compressor features. The first one is smooth operation, low noise and vibration, reducing the impact on the environment. Second, beautiful appearance, outdoor installation, compressor, save space: compact system design, easy to install and maintain; remove the machine room, save floor space, and save rent. Third, excellent low temperature performance, high efficiency and energy saving (high volume efficiency): in medium and low temperature applications, the volume efficiency is more than 30% higher than that of traditional piston machines. Example: One set of medium and low temperature system for a convenience store. Repeat the advantages of scroll compressor. First, low noise; Second, it has a high efficiency within the range of its adapted cooling capacity; Third, the unique design of the scroll compressor makes it a current energy-saving compressor; Fourth, the scroll compressor runs smoothly, has little vibration, and has a quiet working environment. It is also known as "ultra-static compressor"; Fifth, the torque change is small, the balance is high, the vibration is small, and the operation is stable, so that the operation is simple and easy to realize automation; Sixth, there is no reciprocating mechanism, so the structure is simple, small size, light weight, few parts (less wearing parts), and high reliability; Seventh, the main operating parts of scroll compressor scrolls are only worn and have no wear, so they have a longer life and are known as maintenance-free compressors. Finally, scroll compressors have disadvantages. First, Hitachi water source heat pump compressors have high sealing requirements and complicated sealing structures. Second, the surface of its moving parts is mostly in the shape of a curved surface. The processing and inspection of these curved surfaces are more complicated, and some require special equipment, so the manufacturing cost is higher. Third, between moving parts or between moving parts and fixed parts, it is often necessary to maintain a certain movement gap to achieve the seal, and the gas will inevitably cause leakage through the gap, which limits the difficulty of the rotary compressor to achieve a larger Compression ratio, therefore, most rotary compressors are mostly used in air conditioners. Scroll compressors have many advantages that are the reason why people use scroll compressors, but its disadvantages cannot be ignored. The advantages and disadvantages of the scroll compressor and its working principle are described in detail above. I hope it can help you better understand and understand the scroll compressor.
