Problems solved by technology

When the frequency or speed of the compressor system is low, the supply of lubricating oil may be too low, which reduces the lubrication effect of various components in the compressor, thereby reducing the performance of the compressor
In the case of high frequency or rotational speed of the compressor system, the supply of lubricating oil may be too high, which will cause the heat exchange efficiency of the heat exchanger located downstream of the compressor to decrease, and will also cause the lubricating oil in the compressor to be short-lived. Dry out, damage the compressor

Embodiment Construction

[0050] The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the invention.

[0051] The following will refer to figure 1 The basic configuration of a compressor according to an embodiment of the present invention is described. although figure 1 The compressor is shown in a vertical position, but it is understood that the teachings of the present invention are also applicable to compressors in an inclined or horizontal position.

[0052] Such as figure 1As shown, the compressor 1 includes a substantially closed cylindrical casing 10 , and the casing 10 includes a main body 11 located in the middle and a top cover 12 and a bottom cover 13 fixed to the main body 11 at two axial ends. The main body 11 is equipped with a suction joint 14 for sucking refrigerant, and the top cover 12 is equipped with a discharge joint 15 for discharging compressed refrigerant. Between the main body 11 and the top cover 12 , a partition...

Abstract

The invention provides an oil supplying device used for a compressor. The oil supplying device comprises a pump, an oil supplying channel and a valve component, wherein the pump is driven by a rotating shaft of the compressor, and comprises an oil inlet and an oil discharging hole, the oil inlet is in fluid communication to an oil sump of the compressor, and lubricating oil is stored in the oil sump; the oil supplying channel comprises a first end part which is in fluid communication to the oil discharging hole; the valve component is arranged in the oil supplying channel, and is configured to implement openness changing operation by responding to the pressure difference at two sides of the valve component. The invention also provides the compressor including the oil supplying device.

Description

technical field [0001] The invention relates to an oil supply device for a compressor and a compressor comprising the oil supply device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] As we all know, lubricating oil needs to be supplied between the various components in the compressor to play the role of heat dissipation, sealing, and reducing wear. In the prior art, the lubricating oil is usually carried to the parts to be lubricated by means of refrigerant. However, for a variable-speed compressor such as an inverter compressor, the amount of lubricating oil carried by the refrigerant is often related to the system frequency of the compressor (such as the speed of the driving mechanism or the rotating shaft). In the case of low frequency or rotation speed of the compressor system, the supply of lubricating oil may be too low, so that the lubric...
