Description

The coal mine hydraulic prop Y*****0 is the fittings on the hydraulic support of the fully mechanized coal mining face, its main parts are the outer cylinder, the middle cylinder and the live column.

Let's start with the structure composition of the coal mine hydraulic prop Y*****0. As I said just now, its structure mainly consists of three parts:

I. Coal mine upright jack Y*****0 outer cylinder

The outer cylinder is composed of the cylinder bottom and cylinder barrel welded together, and the upper end is installed with a guide sleeve, which plays the role of lifting limit and guiding to the middle cylinder, as well as the sealing element supporting the cylinder.

2. Coal mine upright jack Y*****0 medium cylinder

The middle cylinder of the coal mine column jack Y*****0 is composed of cylinders welded or cocked together with the plunger, and the bottom of the plunger also has a check valve that can be opened, that is, the bottom valve, to separate the two pressure Chambers. The large piston chamber in the outer diameter is separated from the ring chamber by an internal dynamic piston seal, and a screw-in or integrated guide sleeve is provided at the upper end for lifting restriction and guidance of the live column, as well as support of the outer sealing element.

3. Coal mine upright Jack Y*****0 live column

An integrated or screwing plunger is provided at the bottom of the live plunger with a guide ring and an external dynamic piston seal to separate the live plunger chamber from the annular chamber.

The coal mine column Jack Y*****0 is only one of many hydraulic support columns, but they are all similar in structure and work in the same way.We can supply the following types of hydraulic column jack such as DZT******0, F**0A**0, GF*****0, H*******0, KF**0.*1, LZ*****0, etc. 

I am waiting for your enquiry and expecting to give our best service to you.
