How long does it take for the YT28 air leg rock drill to drill an eye?

The reason for the low drilling speed of the mining rock drill: YMJT03

First, the working air pressure is low;

the second is that the air leg is not flexible in telescoping, the thrust is insufficient, and the fuselage jumps behind;

third, the lubricating oil is insufficient;

Fourth, the blowing water flows into the lubrication part;

Fifth, the silencer cover freezes, affecting the exhaust;

Sixth, the main parts wear and tear exceeds the limit;

Shandong Zhongmei Seven is the phenomenon of "washing hammer".

It is widely used in quarrying, mining, roadway excavation and various rock drilling operations to drill blasting holes, and is an indispensable and important tool in mining, water conservancy, building materials, energy, transportation, military industry and geological engineering. The rock drill is recommended to use Tianshui Jufeng YT-23 air leg rock drill.

YT23 air leg rock drill is a new type of high-efficiency rock drilling machinery. The YT28 rock drill is suitable for drilling horizontal, inclined and vertical blast holes in medium-hard or hard (F 8 18) rock, with a diameter of 34 42 mm and an effective and economical drilling depth of up to 5 meters.

YT28 air leg rock drill adopts air-water linkage, rapid return of air leg, air pressure adjustment and other mechanisms. The control handle is centralized with the handle body, the mechanism is novel and the operation is convenient. The equipped sound attenuating cover can effectively reduce noise and change the exhaust direction at will, improving the working conditions on site.

Compared with the same type of rock drill: light weight, low noise, high efficiency and good economic effect.

YT28 air leg rock drill is the most modern rock drill product, it adopts the design technology of modern rock drill, compared with the same type of products, has the advantages of high efficiency, low noise, light weight, good economic effect, fast footage speed and so on. It has superior performance and is the most reliable to use. The most efficient rock drill.

It is most suitable for large-scale mines, medium-sized mines and tunnel drilling operations, and has the best response from domestic users, with a market share of more than 70% in the North Korean market.

YT29A air leg rock drill is a heavy-duty air leg rock drill, with the characteristics of high efficiency and low consumption, especially suitable for railway, highway, hydropower and other construction use, but also metallurgy, coal and other mine roadway excavation and various rock drilling operations replacement products. YT29A air leg rock drill is suitable for drilling horizontal and inclined holes on medium and hard (F=8 18) rocks, and can also drill meow rod holes upwards, with a blast hole diameter of 34-45 mm and an effective and economical drilling depth of 5 meters. According to the size of the roadway section and the working conditions, it can be matched with FT160A air legs, FT160C long air legs, FT160B short air legs or FT170 air legs, and can also be matched with drill rigs or drill stands for dry and wet rock drilling.

The YT29A air leg rock drill is suitable for drilling horizontal and inclined blast holes in medium and hard rocks, as well as bolt holes in the roof vertically upwards, and vertically downwards (shaft drilling) in conjunction with the annular hanger. It can be used with FT170A or FT170B air legs, as well as with drill stands. The diameter of the blast hole is generally 34 42 mm, and the depth of the economical blast hole can reach more than 5 meters.

This is a new type of rock drilling machinery of YT29A gas leg rock drill of Shandong China Coal. It is widely used in mine roadway excavation and various rock drilling operations to drill blasting holes, and is an indispensable and efficient tool in coal, metallurgy, railway, transportation, water conservancy construction and national defense and other stone projects. ymhy1
