Abstract

The invention relates to the technical field of refrigerating systems, and discloses an air supply system of a compressor. An evaporator; a condenser; a liquid taking opening of the liquid taking pipeline is communicated with a liquid discharging opening of the evaporator; a gas taking port of the gas taking pipeline is communicated with an exhaust port of the condenser; the injection device is provided with a first refrigerant inlet and a first refrigerant outlet, a liquid outlet of the liquid taking pipeline and an exhaust port of the gas taking pipeline are both communicated with the first refrigerant inlet, and the injection device is used for mixing a liquid refrigerant from the liquid taking pipeline and a gas refrigerant from the gas taking pipeline into a gas-liquid two-phase refrigerant; and the gas supply tank is provided with a second refrigerant inlet and a second refrigerant outlet, and the second refrigerant inlet is communicated with the first refrigerant outlet. The medium-temperature and medium-pressure gas-liquid two-phase refrigerant can be provided for the gas supply tank through the injection device, so that the gas pressure in the gas supply tank is increased, and the time for starting the compressor is shortened. The invention further discloses a control method of the air supply system for the compressor.

Description

technical field [0001] The present application relates to the technical field of refrigeration systems, for example, to a compressor air supply system and a control method for the air supply system. Background technique [0002] At present, compressors have become one of the mainstream development directions of centrifugal compressors due to their high efficiency, energy saving, and oil-free characteristics. Air supply to gas bearings is a key link to ensure the normal operation of compressors. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] The commonly used air supply method is to take liquid from the evaporator, pass through liquid pumps, air supply tanks and other devices, and then supply air to the compressor. The gaseous refrigerant is used to increase the pressure of the air supply tank, resulting in too long a preparation time for starting the ...
