Advantages of 1. down-the-hole impactor and drill bit in water well construction
1. High drilling efficiency, long drilling tool life, down-the-hole impactor rock drilling, the medium is air, there is no problem of recovery and treatment of flushing medium, and the auxiliary time is reduced.
2. The use cost is low. The down-the-hole impactor requires small shaft pressure on the drilling rig, low speed, low torque, low natural power consumption, relatively thin drill pipe diameter, easy installation and disassembly, and long service life.
3, DTH impactor drilling, the hole wall is more complete, no other media pollution, basically can maintain the original formation structure and water permeability, reduce the well cleaning time, save the cost.
4. In the formation of serious leakage and unstable formation of hole wall, the down-the-hole impactor and pipe drilling can be used to completely solve the problem of repeated operation.
5. Since the DTH impactor uses wind as the power source, it is constructed in the cold winter, which greatly reduces the cold-proof workload in the previous winter construction.
Maintenance after 2. use
Proper, timely maintenance can extend the life of the DTH impactor components and can greatly reduce the cost of use. Clean the parts of the down-the-hole impactor in time. In many cases, the performance of the impactor is reduced due to the wear of the outer sleeve or the wear of the internal parts. At this time, the down-the-hole impactor needs to be repaired and more detailed inspection is required. If all parts are in good condition, it is necessary to apply lubricating oil and keep it after correct installation according to the assembly diagram. However, in order to ensure that your down-the-hole impactor maintains the best performance, you must regularly maintain the down-the-hole impactor.
3. regular maintenance
Any equipment needs regular maintenance. Only when we carefully do each maintenance, can you be handy when you need to use it. The DTH impactor is also used with this. However, the maintenance of the DTH impactor after we use it is much simpler. We only need to determine whether the internal piston moves well and whether the lubrication is appropriate. If you have used the DTH impactor for a long time then you need to press the method for routine maintenance of the DTH impactor:
1) Replace all "O" rings, check valve seals and springs inside the down-the-hole impactor, which can ensure that the down-the-hole impactor reduces air consumption.
2) Ensure good lubrication of the internal moving parts (piston) of the down-the-hole impactor, and remove all sharp corners and burrs formed during the use of the piston (it is recommended to use an oil stone to grind off the sharp corners and burrs of the piston)
3) Ensure that the check valve is unblocked and returned correctly.
4) Wear of outer sleeve and cylinder shall be replaced in time as required.
5) Install correctly according to the installation sequence in the manual or installation diagram.
6) Keep it properly.
