How to choose the various types of hydraulic rock drills on the market?

The first thing to consider when buying a hydraulic rock drill is, of course, low energy consumption, long life, environmental protection and efficient equipment, as well as to look at their own use requirements and construction environment, when purchasing, they should understand the relevant parameters of the product with the merchant, and explain their own use, such as the diameter and depth of the hole, as well as the variety and hardness of the rock, so that it is convenient for the business to judge which machine can meet the impact energy requirements. At present, some high-tech manufacturers make hydraulic drills very efficient, the work efficiency is 3-10 times that of traditional air drills, but the energy consumption is only 1 3 of wind drills, and it is more and more lightweight, easy and convenient to operate, you can search and understand.

Atlas occupies the vast majority of the hydraulic rock drill market in the country. The quality is absolutely reliable, that is, the highest level.

Typical models are 1238, 1838The domestic imitation of 150 is 1238, and 175 is 1838; 1238 is a product 30 years ago, the domestic imitation of 150 has almost matured, 1838 is a product 20 years ago, the domestic has not yet done a successful job, science and technology gap. 1838 wants seven or eight hundred thousand, 1840 wants about 1.1 million, it seems.

If the imitation is good in China, it is estimated that ** will immediately dive.

Montebay, France, is said to be the first company to make rock drills.

Furukawa, Japan, is doing well, too.

The upstairs is very complete.

In addition to the upstairs there is also a Finnish Dover rock drill, which seems to have just entered the Chinese market.

At present, there are more imported rock drills in China are Sweden's atlas-copco 1838 rock drills and Sandvik's rock drills, these two imported rock drills, commonly used or atlas-copco efficiency is relatively high, but with the rock drilling equipment, the failure rate of atlas is relatively high, Sandvik's failure rate is low, but more expensive.

According to the user's aperture requirements, there are 41mm, 45mm, 51mm, 64mm, 76mm, 89mm, 102mm, 115mm and other specifications of aperture diameter. Hengri Heavy Industry's W89A hydraulic drilling rig is equipped with an 89mm drill bit as standard, drilling a 90mm hole diameter.

The maximum diameter can be drilled to 80mm, because the maximum drill bit is only 80mm, and the hole is about 83mm. Xi'an Hengzhao working conditions bridge and tunnel materials.

Flush acre power:

Impact frequency: 50Hz

Rotation speed: 350 (r min).

Maximum torque: impact pressure belt regret force: stupid search is 17mpa

There are three main components: First, the main engine of the rock drill.

Second, the oil injector.

3. Air legs. Each of the three parts also contains a number of its own parts.

The rock drill is divided into hydraulic and pneumatic, and there are air leg type and handheld type in the air movement, the composition of these accessories is not the same, the hydraulic pressure is relatively complex, the pneumatic is relatively simple, the air leg type and the handheld type, there are dozens of large pieces, hundreds of small pieces, such as more than 10 sealing rings.

Jining Shengdu rock drill, they are a professional manufacturer, I think it is the largest factory in China, we buy over there, the quality of the distribution of Shengdu brand is very reliable.

China's Tianshui Liaoyuan brand, foreign Atlas, Sandwich, Tianshui brand is not necessarily Tianshui Liaoyuan brand, Tianshui is the production plant for Tianshui wind rock drill factory, so there are many indiscriminate filling, Jufeng? Hehe, PPC is really NB!

Shandong coal manufacturers are good, and they are cheap.

Lower Shengdu Rock Drill Everything is settled.

The same is generally hydraulic.

The efficiency of the wind is low, and it is cheap.

Hydraulic high efficiency, cost-effective, difficult to maintain, pneumatic opposite.

A rock drill is a tool used to mine stone directly. It drills holes in the rock to blast the rock with explosives to blast the rock and complete the stone mining or other stone work. In addition, the rock drill can be converted into a saboteur to break up hard layers such as concrete.
