Problems solved by technology

It can be seen from this that the air inlet and outlet on the stator are arranged in such a way that the gas input is relatively passive, which requires additional energy consumption, and also greatly limits the gas input flow rate, which in turn affects the working efficiency of the entire compressor pump.

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Such as Figure 1 to Figure 7 As shown, it is a preferred embodiment of the compression pump applied with the swirl type auxiliary air intake device in the present invention. The compression pump includes a pump casing 1 with a cylindrical cavity, a cylindrical cylinder 3, a hollow rotor 5 arranged in the cylinder 3, a cock 6, a follower partition 7, a guide arranged in the center of the rotor 5 Air shaft 8 and a swirl type auxiliary air intake device.

[0034] Wherein, when this embodiment is applied to the compressor, the end of the pump housing 1 is provided with a machine cover 11 with an air vent 11a, see figure 2 and image 3 .

[0035] The cylinder body 3 is coaxially arranged in the pump casing 1 and has a distance from the pump casing 1. The cavity between the cylinder body 3 and the pump casing 1 is the swirl air intake p...

Abstract

The invention discloses a spiral-flow auxiliary air intake device, which comprises end covers (2) and a flow deflector (4), wherein the end covers (2) are respectively fixed on both sides of a cylinder body (3) during installation; the flow deflector (4) is arranged between the end covers (1) on both sides, and the front of the flow deflector (4) faces an air intake (31) arranged on the circumference of the cylinder body (3) during installation; and each of the end covers (2) is provided with an air intake (21) at a position behind the back of the flow deflector (4). Compared with the prior art, the auxiliary air intake device can effectively reduce energy consumption as air input into the cylinder body withstands no pre-pressure; in addition, the spiral-flow air intake mode can greatly increase air intake flow considerably improve working efficiency of a compression pump and be applied to various compression pumps. The invention also discloses a compression pump applying the spiral-flow auxiliary air intake device. The flow deflector fits a pump casing and the cylinder body to ensure the flow deflector has maximum flow deflecting effect.

Description

technical field [0001] The present invention relates to the technical field of compression pumps, in particular to the field of compression pumps with a cylindrical cylinder body and the air inlet of the cylinder body is arranged on the peripheral surface, in particular to a compression pump cylinder for such a compression pump The swirl-type auxiliary air intake device of the body and the compression pump applied with the swirl-type auxiliary air intake device. Background technique [0002] There are two common types of compressors currently on the market: one is a reciprocating compressor, which mainly includes a cylinder and a piston rod. The motor drives the piston rod to move, and then compresses the conveying medium (such as gas) in the cylinder. The inertia force is difficult to balance, the vibration is large, the speed is low, and the volume is large, and the efficiency is not high; the other is a rotary compressor, which mainly includes a cylindrical cylinder with ...
