Problems solved by technology

However, there are still some problems that need to be solved in this case. First, the casting quality of the cylinder liner is not guaranteed. If it cannot meet the requirements of the compressor, it will bring adverse effects; This kind of cylinder also needs to redesign and manufacture a piston with a diameter of 260, which increases the design cost without knowing it, and also brings new troubles to processing and manufacturing.

Embodiment 1

[0027] like figure 1 As shown, a piston compressor cylinder of the present invention, the cylinder head 1 is installed on one end of the cylinder body 4, and the cylinder head 1 is provided with a circular through hole 5 leading to the cylinder body 4; the material of the clearance adjustment cover 2 It is made of cast iron to save cost, and its longitudinal section shape is similar to a flat H-shape. It is installed in the through hole 5 and closely fits with the inner wall of the through hole 5; A sealing gasket 6 is provided at the contact position, and the outer end surface of the clearance adjustment cover 2 is provided with an annular groove at the outer circumference position. The gland 3 is a circular steel plate, and the inner circular end surface of the gland 3 is stuck in the annular groove. Four fixing bolts are evenly installed along the circumference, and the sealing gasket 6 between the clearance adjusting cover 2 and the cylinder head 1 is compressed and sealed...

Embodiment 2

[0030] like figure 2 As shown, the difference between the present embodiment and the first embodiment is only that the longitudinal section shape of the clearance adjustment cover 2 is similar to a flat U-shape, the U-shaped opening points to the outside of the cylinder body 4, and the piston 9 moves to the top dead center. The clearance volume V on the cylinder block 4 side in the through hole 5 0 Larger than the inherent clearance volume of the cylinder; the clearance adjustment cover 2 in this embodiment can have different models according to the depth of its U-shaped sealing port extending into the through hole 5, so as to adapt to different clearance adjustment needs . The clearance volume V in this example 0 Compared with the clearance volume in Embodiment 1, the displacement Vm of the compressor cylinder will have different reductions according to different clearance adjustment cover models, so that different exhaust volumes can be satisfied on the basis of reducing ...

Embodiment 3

[0032] like image 3 As shown, the difference between this embodiment and the first embodiment is that the clearance adjustment cover 2 is a plate-shaped structure, installed at the outer port of the through hole 5, and the axial position of the clearance adjustment cover 2 is not provided with a protrusion. A screw hole 8 is directly opened on the clearance adjustment cover; the material of the clearance adjustment cover is steel; at this time, the clearance volume V 0 The largest, that is, the reduction of the displacement of the compressor is the largest, so the displacement Vm of the compressor is the smallest compared to the first and second embodiments.

Abstract

The invention relates to an air cylinder of a piston type compressor, aiming at providing the air cylinder of the piston type compressor, which has the advantages of simple structure, low manufacturing cost and convenience for batch production of air cylinders in different air displacements. The air cylinder of the piston type compressor comprises a cylinder cover and a cylinder body; the cylinder cover is arranged at one end of the cylinder body in a sealing manner; the air cylinder further comprises a clearance adjusting cover; the cylinder cover is provided with a through hole communicatedto the inside of the cylinder body; and the clearance adjusting cover is arranged in the through hole and is fixedly connected with the cylinder cover in a sealing manner. By adopting the structure, a matched cylinder sleeve for meeting the requirement on different air displacements does not need to be specially produced; the requirement on the different air displacements can be met by making theclearance adjusting covers in different model numbers suitable for air cylinder covers, so that the air cylinder with the same diameter has a wider application range and the diameter series of the air cylinder can be reduced as much as possible; the use frequency of the air cylinder with the same diameter is increased; large-batch production can be realized, so that the production cost of the aircylinder is reduced and further the production cost of the whole compressor is reduced.

Description

technical field [0001] The invention relates to a piston type gas compressor, in particular to a cylinder device of a reciprocating piston type gas compressor. Background technique [0002] For the cylinders of existing reciprocating piston gas compressors, because compressors in different application fields have different displacement requirements, it is often necessary to process different series of cylinders, so it is necessary to invest a lot in cylinder design and cylinder production. The human and material resources increase the social cost of the cylinder, and also increase the production cost of the cylinder, which brings unnecessary trouble to the compressor production industry. [0003] Of course, in order to meet the needs of different displacements, some people will modify the existing cylinders. For example, the existing compressor cylinder is a cylinder with a bore diameter of 280. If a cylinder with a smaller displacement is required, such as a bore diameter o...
