These rigs are offered in various technical specifications as per the client's specific need.is mainly applicable to industrial and civil drilling, geothermal drilling, has the advantages of compact structure, fast advancing, mobile and flexible wide application region etc.. Pneumatic well drill is especially suitable for water intake in
Precautions when working at low temperature
1. In the low temperature environment, the land will become hard, so when we choose the site, we need to have some requirements. The site needs to be flat and the road needs to be unblocked. This must be ensured.
2. The drilling machine mainly uses triangular support, especially in the case of low temperature, we should ensure that the support of the drilling machine is firm and reliable. Our staff need to regularly check and deal with hidden dangers in time once they are found. We must not be careless
3. Although we work at low temperature, we can not ignore the problem of fire prevention. The configuration of fire-fighting equipment must be reasonable and meet the fire-fighting requirements.
4. Low temperature, low temperature, what is the most important? Of course, our friends should pay attention to their warmth when working. Only when they are warm can we better put ourselves into work.
5. The temperature is low, which will definitely have certain impact on the construction. We must pay attention to warmth and safety
What aspects should we pay attention to in the drilling process of water well drilling rig?
Bit plays a very important role in the drilling of water well drilling rig, but the quality of a bit directly affects the efficiency and quality of water well drilling. Therefore, in the selection process, we should pay attention to the selection and use of lower bit. When we are operating the drill bit, we must pay attention to several aspects in order to better production and operation.
1. After the drilling structure of the drill bit of the water well drilling rig is drilled, the central drilling tool needs to be replaced in time. First, the hole bottom needs to be cleaned, and then the residue at the hole bottom needs to be blown away. After the drill bit stops rotating, the drilling tool in the water well drilling rig can be lifted up slowly. When the lifting force is just enough to lift the drilling tool, it is the most appropriate.
2. During the drilling process, the drill bit of the water well drilling rig shall be summarized. It is also necessary to carefully observe the follow-up situation of the casing, timely understand the specific situation in the hole, and keep the hole clean when necessary. Moreover, the drill bit in the water well drilling rig shall not be pulled out by force during the drilling process.
3. Sometimes there will be more residual rock slag at the bottom of the hole of the water well drilling rig, and the rotating part of the eccentric bit will be stuck by the rock slag, which will affect its retraction and production. At this time, it is necessary to transport air pressure, clean the hole again, make the DTH hammer work in a short time, and then lift the central drilling tool again.
