Problems solved by technology

Although this design can ensure the cooling of the motor, due to the pressure difference, the refrigerating machine oil accumulates in the motor cavity, which makes the oil level at the oil suction pipe low, and the oil supply is likely to be insufficient, and the loss of rotor oil churning cannot be ignored.

Embodiment

[0020] Such as Figure 2~3 As shown, a self-cooling horizontal rolling rotor compressor, the compressor structure is as follows: parts 2 (lower cylinder head), 3 (cylinder), 4 (upper cylinder head) are assembled together by bolts to form a static compression part Part 9 (crankshaft), 6 (piston) and 7 (vane) constitute the moving part, which is driven by 5 (motor) to rotate the crankshaft to complete the process of compressing the gas. 1 (lower muffler) is installed outside the lower exhaust to start To eliminate exhaust noise. 8 (intake pipe) and 10 (exhaust pipe) complete the gas input and output work, and the whole structure is sealed by the closed shell. 11 (air return pipe) acts as an exhaust guide, and is used to guide the exhaust to cool the motor and improve the height of the oil level on the side of the pump body.

[0021] With 4 (upper cylinder head) as the partition, the inside of the housing is divided into a compression chamber and a motor chamber. Exhaust gas e...

Abstract

The present invention relates to a self-cooling horizontal rolling rotor compressor, which comprises an upper cylinder cover, an air cylinder, a lower cylinder cover, an electric motor, a piston, blades, an air inlet pipe, a crankshaft, an exhaust pipe, a muffle as well as a return air pipe; wherein, the upper cylinder cove is provided with a return air hole; the exhaust pipe is arranged on the pump body side; exhausted air enters into the return air pipe through a channel arranged on the pump body and is led into the end of the electric motor far from a pump body from a housing or a housing cover through the return air pipe in order to directly cool the electric motor; then the exhausted air enters into a compressing cavity through the return air hole on the upper cylinder cover and is exhausted through the exhaust pipe. Compared with the prior art, the present invention improves the operation conditions of the horizontal compressor, so that the reliability of the compressor is greatly improved.

Description

technical field [0001] The invention relates to a self-cooling horizontal rolling rotor compressor, in particular to a heat pump water heater which prevents the refrigerant on the side of the condenser from migrating into the evaporator and the interior of the compressor. Background technique [0002] Generally speaking, as a machine for compressing fluid, a compressor is composed of a closed container, a motor and a compressor. The airtight container has a certain internal space; the motor component is installed in the airtight container to generate driving force; the compressor compresses the gas through the driving force of the motor. [0003] According to the type of installation, the compressor is divided into two types: horizontal and vertical. Usually, the axis of the electric part and compression part of the horizontal compressor is set parallel to the installation base of the horizontal compressor. If the vertical compressor If the machine is directly changed to a ...
