Problems solved by technology

[0002] The screw air compressor uses the rotation of the male screw and the female screw to mesh with each other to change the volume of the volume, so as to realize the compression of the gas. For the oil-injected screw machine, the oil is indispensable. The existing technology Due to the influence of the working environment of the fuel injection device, the oil pipe may be blocked after a long time of use, which will affect the efficiency of the fuel injection, resulting in low working efficiency of the machine or even damage to the machine, and there will be uneven fuel injection

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Figure 1 to Figure 5 Among them, an oil injection device for a screw air compressor includes a male screw 8, and also includes an oil injection rod 1 and an oil pipe 2. A rotating shaft 6 extends from both ends of the oil injection rod 1, and the rotating shaft 6 is connected to an external power device so that the oil injection Rod 1 rotates at a suitable rotational speed.

[0019] The oil pipe 2 is connected with the external oil, and the outer wall of the oil spray rod 1 is provided with a spiral groove 3 meshing with the male screw 8, and a number of oil retaining blocks 4 are arranged in the spiral groove 3 and are connected with the oil retaining block 4. Adapted through hole, the oil retaining block 4 can slide freely in the through hole, and the oil retaining block 4 is also connected with a return spring 7 that goes through the through...

Abstract

The invention discloses an oil injection device of a screw air compressor. The oil injection device comprises a male screw (8), and further comprises an oil injection rod (1) and an oil pipe (2); oneend of the oil pipe (2) extends into the oil injection rod (1); the other end of the oil injection rod (1) is connected to external oil liquid; a spiral groove (3) which meshes with the male screw (8)is formed in the outer wall of the oil injection rod (1); a plurality of oil blocking blocks (4) are arranged in the spiral groove (3); through holes allowing the oil blocking blocks (4) to vertically slide in the axial direction of the oil injection rod (1) are formed in the spiral groove (3); the oil blocking blocks (4) are connected with reset springs (7) penetrating through the through holes;oil injection plates (5) which are attached to the oil blocking blocks (4) are arranged on the spiral groove (3) and communicate with the oil pipe (2); and rotating shaft (6) are arranged at the twoends of the oil spraying rod (1) in an extending mode. The oil injection device has the beneficial effects that oil injection can be more uniform, and the blockage of the oil pipe can be avoided.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an oil injection device for a screw air compressor. Background technique [0002] The screw air compressor uses the rotation of the male screw and the female screw to mesh with each other to change the volume of the volume, so as to realize the compression of the gas. For the oil-injected screw machine, the oil is indispensable. The existing technology Due to the influence of the working environment of the fuel injection device, after a long time of use, the fuel pipe may be blocked, which will affect the efficiency of the fuel injection, resulting in low working efficiency of the machine or even damage to the machine, and uneven fuel injection. Contents of the invention [0003] The object of the present invention is to solve the deficiencies of the prior art, and provide a screw air compressor oil injection device which sprays oil evenly and avoids clogging of oil pip...
