Problems solved by technology

[0004] However, the above-mentioned conventional two-stage compressor has the following disadvantages, wherein, because the positions of the first compression member 40 and the second compression member 50 are all concentrated at one end of the connection shaft 30, the force on the connection shaft 30 is uneven, resulting in The connecting shaft 30 is unbalanced when it rotates, and noise is generated with the unbalanced rotation; in addition, when the refrigerant enters the second compression member 50 from the first compression member 40, an additional guide line is required, resulting in an increase in the volume of the compressor , resulting in bulky appearance of the compressor

Abstract

The invention discloses a multistage heat pump compressor. The multistage heat pump compressor comprises a closed shell, a separation assembly, a driver and at least two pressurizing mechanisms, the separation assembly is arranged in the closed shell and separates the closed shell into a first chamber and a second chamber which are mutually separated, and the first chamber is formed in the second chamber; the driver includes a body and a transmission shaft penetrating through the body, the body is accommodated in the first chamber, and the transmission shaft penetrates into the second chamber; and each of the pressurizing mechanisms is accommodated in the second chamber and is connected with the transmission shaft, and the pressurizing mechanisms are formed at two sides of the body to be driven by the driver to rotate. The bearing of the transmission shaft is uniform, so the rotation stability of the transmission shaft is improved and the noise is reduced, thereby the work efficiency of the compressor is enhanced.

Description

technical field [0001] The invention relates to a compressor, in particular to a multi-stage heat pump compressor. Background technique [0002] The heat pump compressor is a machine that must be used in heating machines or water heaters. It is mainly used to transport refrigerant through a specific process for heat exchange to reduce or increase the ambient temperature. The heat pump compressor is mainly composed of an evaporator, a compressor, an expansion valve, and a condenser. It transfers heat through natural heat exchange, and converts the useless heat in the natural environment into our daily usable energy through a thermal cycle and a small amount of electric energy. thermal energy. [0003] Among them, in order to increase the heat production efficiency of the compressor, a two-stage compressor is usually used to increase the gas pressure. Such as figure 1 As shown, it is a traditional two-stage compressor, which is mainly provided with an electric component 20 ...
