ST 350 Borehole Drilling Rig Advantages:

 

1.YUCHAI engine;
2. Walking Type: crawler mounted ,trailer mounted for choice.
3. Hydraulic oil pump:Parallel gearbox design separates the oil pump unit, the power supply is adequately distributed, the hydraulic system is uniquely designed, and the maintenance cost is small;
4.Rotary head device:gearbox integrated casting, dual motor power, large torque, durable, low maintenance costs;
5.Drilling machine chassis:professional digging chassis, durable, heavy bearing, wide chain plate, less damage to hard roads;
6.Lifting force:design composite tower, 3.4m long stroke, double cylinder lift capacity 18 ton.
7. Each rig is equipped with a relief valve to raise the boom to protect the cylinder and ensure work safety;
8. Each hydraulic oil pipe is covered with a protective jacket to make the oil pipe last longer.

 

ST 350 Borehole Drilling Rig Drilling Process 

 

After the well is completed, measure the water level of the water outlet well and the corresponding water output according to the drainage condition of the drilling machine, and then determine the total head of the water pump according to the height difference from the ground to the dynamic water level and the irrigation method you adopt, and the required working head of the water pump. The flow of the water pump shall not exceed the water flow through the well. The corresponding water pump shall be purchased on the premise of the above two items.

 

What should be paid attention to when using DTH bit?

 

1. According to the rock conditions (hardness, corrosion) and drill type (high wind pressure, low wind pressure) to choose the drill bit.

Different forms of alloy and cloth teeth are suitable for drilling different rocks.

Choosing the right drill bit is the premise to get the best use effect;

2. When installing the drill bit, gently insert the bit into the drill bit bit sleeve of the drill bit impactor. Do not force collision to avoid damaging the drill bit

In the process of rock drilling, it is necessary to ensure that the pressure of air on the drilling rig is sufficient;

3.In case of intermittent work , the compressed air system of the drilling machine should be checked to ensure that there is no rock slag in the hole during the drilling process;

4. If a metal object is found falling into the hole, it should be pulled out with magnet or other methods in time to avoid damaging the bit;

5.Pay attention to the size of the hole drilled when replacing the drill bit.

If the bit diameter is too worn out but the hole has not been drilled, do not update the bit to avoid sticking.

The operation can be completed with old drill bits that have been used and worn out to approximately the same diameter
