ST 350 Water Well Drilling Machine  Advantages

 

With hydraulic technology,supporting high torque hydraulic motor rotation and large bore hydraulic cylinder push, the multi cylinder engine of famous factory provides power for the hydraulic system, two stage air filter, air compressor air intake design

 

High oil temperature in the drill process

 

The high temperature in the drilling rig is generally divided into the high temperature of the gearbox, the high temperature of the hydraulic oil, and some are the high temperature of the engine cooling liquid. In fact, the reason for the high temperature of the gearbox is very simple. The main reason is that the size and shape of the bearing or gear and housing are not standard or the oil is unqualified. Now let's give you a detailed analysis.Hydraulic oil temperature is too high:

First of all, the temperature of hydraulic oil is too high. According to hydraulic theory and maintenance experience in recent years, the main reason for the high temperature of hydraulic oil is too fast heat generation and too slow heat dissipation. The oil inlet pipeline and hydraulic oil tank of the hydraulic pump are not sealed tightly, the oil inlet filter element is blocked, the hydraulic system pipeline is not unblocked, and the internal leakage of the hydraulic pump will cause a large amount of heat to be generated in the hydraulic oil, so that the temperature of the hydraulic oil will rise rapidly due to excessive heat generation.

 

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.
