Compressor and capacity adjusting method, device and equipment of compressor

The invention discloses a compressor and a capacity adjusting method, device and equipment of the compressor. The capacity adjusting method of the compressor comprises the steps that 1, the capacity adjusting moment for conducting capacity adjusting control over the compressor is determined based on electric current fluctuation of the compressor; 2, when capacity adjusting control over the compressor is conducted at the capacity adjusting moment, the pressure difference of the high pressure and the low pressure of the compressor is acquired; 3, the pulse loading time corresponding to the pressure difference is determined, and 4, starting and stopping of a capacity adjusting electromagnetic valve are controlled according to the pulse loading time. According to the compressor and the capacity adjusting method, device and equipment of the compressor, the technical problems that abnormal situations and control disorders occur due to too fast loading of the compressor are solved.
