Details

The YT28 rock drill is a kind of machinery installed on the air leg, relying on compressed air to push the piston reciprocating motion, to achieve rock crushing and drilling. The following is a detailed introduction about the working principle of YT28 rock drill：
The YT28 rock drill pushes the piston to reciprocate by compressed air. In the stroke, the piston strikes the end of the braze, generating an impact force; in the return stroke, the piston drives the brazing tool to rotate, realising the rock crushing and drilling, the leg type rock drill plays an important role in the stone project with its unique working principle, wide range of application, remarkable product features and various models and specifications.

Uses

Mining

In mining, YT28 rock drill is an important tool for roadway boring and quarry mining, which can efficiently drill gun holes and improve mining efficiency.

Railway construction

In railway construction, YT28 rock drill can be used for tunnel boring and roadbed stone works, which can help to complete the rock crushing and drilling work quickly.

Water conservancy construction

Rock excavation and channel construction are often required in water conservancy projects, YT28 rock drill can provide powerful rock drilling capacity to meet these project needs.

National defence project

In national defence projects, such as underground bunkers, tunnels and other construction, YT28 rock drill also plays an important role.

In addition, YT28 rock drill can also be mounted on the drilling truck or drilling frame to work, which further broadens its application scope. YT28 rock drill plays an irreplaceable role in stone construction with its features of high efficiency, energy saving and easy operation.

FAQ

Q: YT28 rock drill precautions?

A: The screw mother and piston are connected by left-handed threads, so pay attention to the direction of rotation when disassembling and assembling;
At the end of the work of the machine, the water pipe should be turned off first, and then run lightly for a few moments to blow clean the residual water droplets in the machine to prevent rust and corrosion of the parts.
Frequently used machine, should pay attention to regular maintenance and maintenance. Keep the machine clean, pay attention to the replacement of damaged and failed parts, to eliminate hidden trouble.

Q: How to adjust the air leg thrust of YT28 rock drill?

A: The rock drill has a fixed air leg control system, and the thrust of the air leg can be adjusted by the air leg adjustment valve. In the process of operation, if the propulsion length of the air leg of the rock drill can not meet the depth of the rock drilling, and it is necessary to move the air leg to change the position of the second propulsion, only need to pull the trigger to push the reversing valve, and then the air leg of the rock drill will be quickly retracted to change the position.
