BZT1500 trailer mounted well drilling rig is a brand-new machine based on independent research and development of our factory. This type of drilling rig has the features of reasonable design, perfect supporting facilities and superior performances. Being equipped with different drilling tools, various drilling techniques such as mud drilling, air-foam drilling, pneumatic down-hole hammer drilling and air-lift reverse circulation drilling can be achieved, thus the construction can be carried out under different geological conditions including clay layer, sandy soil layer, weathered rock, bedrock and others.
The drilling rig is composed of full-trailer chassis, mud pump, drill tower support, diesel engine set, middle vehicle, generator, hoist set, A-leg, rotary table, drill tower and other parts. All components are mounted on the trailer, which makes transportation and shifting more convenient.
Hydraulic system is composed of oil tank, gear pump, get-off control valve, hydraulic cylinder and connecting pipes and the oil tank is equipped with two 1.5kW hydraulic heaters with the voltage of 220V. The power is from self supplied 50kW generator when getting on.
Expansion and leveling of the leg, lifting-falling of drill tower and other operations can be achieved by controlling get-off valve to quickly locate the drilling rig, which makes operations simple and efficient.
★The handles of braking band-type brake and lifting band-type brake of main and auxiliary winches are prohibited to be tightly wrenched at the same time.
★The winch is manipulated to lift drilling tools. Reduce the rotating speed of hoist when lower joints of drilling tools are approaching the upper plane of rotary table in order to prevent the travelling block from lifting too fast and bumping the drill tower.
How to properly maintain a positive circulation rig
1. Avoid being affected by impurities;
2. Reduce various corrosive effects, such as rainwater, chemical substances in the air, etc., entering the machine through the external passages and gaps of mechanical parts, corroding the inside of mechanical parts, accelerating mechanical wear and increasing mechanical failure.
Measures for the use of the water well rig during the running-in period
Reduce load, pay attention to inspection, and strengthen lubrication. As long as the maintenance and maintenance of the construction machinery running-in period are emphasized and implemented as required, it will reduce the occurrence of early failures, prolong the service life, improve the operation efficiency, and bring you more economic benefits.
How to improve the production efficiency of hydraulic water drilling rigs?
1. After the drill bit of the hydraulic water well drilling rig is drilled into the structure, the center drilling tool needs to be replaced in time. First, you need to clean the bottom of the hole and then blow off the residue at the bottom of the hole. After the drill bit stops rotating, the drill bit in the hydraulic water well drilling rig is drilled. It is most suitable when the lifting force is slowly increased and the lifting force is just enough to lift the drill bit.
2. The drilling process summarizes the drill bits of the hydraulic water well rig. It is also necessary to pay close attention to the subsequent working conditions of the casing, to know the specific conditions of the drilling in time, to clean the drilling holes in time, and to drill the drill bit on the water drilling rig. Strong lifting is prohibited during this process.
3. There will be more residue at the bottom of the hydraulic well rig. The eccentric drill bit will be stuck by the slag and affect its collection and production. At this point, it is necessary to deliver compressed air and clean the holes again. And let the down-the-hole hammer work for a short time, the water well rig model, and then re-do the center drill lifting work.
