The core drilling machine adopts hydraulic automatic feeding mechanism to improve drilling efficiency and reduce workers' labor intensity. Fitted with cage, it forms a double-sided supporting star wheel structure, which can withstand strong impact. Four sets of bearings are fixed in the vertical shaft box of the core drilling rig to ensure that the rotary body has enough rigidity to cope with complex geological conditions such as gravel layer and pebble layer. The core drilling rig adopts conical clutch, which has outstanding features such as high transmission torque, easy operation and maintenance-free.

Core drilling rigs are a kind of portable core sampling equipment, which should not be neglected in maintenance. They are also factors to improve the service life of the drilling rig, reduce the incidence of various failures and lower maintenance costs. The following is a brief introduction on how to maintain the core drilling rig.

1、Normal load

Make sure the load of the core drilling rig is within the allowable range. Generally speaking, the wear of parts is proportional to the working load. The greater the load, the greater the degree of wear.

2、Normal temperature

Make sure the operating temperature of the core drilling rig is within the normal range. Long-term high temperature operation tends to accelerate the wear of parts.

3、Avoid impurities

Core drilling rig is the equipment used to drill the strata. In the sampling process, it is inevitable that there will be some splashing sand and some self-generated metal chips and wear products. This time to avoid these impurities into the equipment, otherwise it will accelerate the wear of parts, so it needs to be cleaned and cleaned every day.

4、Avoid corrosion

Core drilling rig is a metal product, it is inevitable that it will react with the surrounding media and cause corrosion corrosion. Although corrosion and corrosion is inevitable, but you can take measures such as cleaning to reduce the impact of corrosion on the machine.
