Product Description
1. water well drilling machine has a hydraulic automatic feed mechanism, improve drilling efficiency,reduce manual labor workers.
2. Card holder mechanism instead of using the ball chuck, can implement non-stop down the lever,easy to operate, safe and reliable.
3. With bottom hole pressure gauge indicates the pressure, easy to grasp hole situation.
4 The handle centralized, easy to operate.
5. Light weight, decomposition and strong, easy to move, adapted to the plains or mountain areas.
Main Features
1. Used for general investigation, geophysical exploration,
high-way and building construction, and blast-hole drilling etc.
2. With hydro-automatic feeding device, and high drilling efficiency.
3. Designed with hydro-chucking unit instead of slips to ensure drilling from stop when changing pipes.
4. Close levers, convenient to operate, safe and reliable operations.
5. Compact in structure. All the drill, water pump and diesel engine installed on one base frame result in space-saving.
6. Light in weight, easy disassembling for transportation and applicable to working conditions in plain and mountain areas.

Cause and judgment of drill pipe sliding down
The drill pipe is fixed on the main winch drum through the steel wire rope, and the drill pipe can be raised or lowered accordingly when the drum is wound or released with the steel wire rope. The power of the drum comes from the main winch motor that has been decelerated for many times. Its stop is realized by the brake directly installed on the reducer. During the lifting or lowering of the drill pipe, if the operating handle is returned to the middle position and the drill pipe cannot stop quickly, there may be three reasons: first, the brake lag; Second, the two hydraulic locks at the outlet of the motor end fail, and the motor cannot stop rotating immediately under the effect of the torque of the wire rope; Three reasons are easy to be ignored. All engineering drilling rigs have a drill pipe release function. The function is that the solenoid valve 3 provides release brake signal oil, and then the solenoid valve 2 connects the oil inlet and outlet of the main winch motor through two oil pipes, so as to ensure that the drill bit can always contact the working face and have a certain pressure during drilling. Under other working conditions, the solenoid valve 2 will disconnect the two oil pipes leading to the inlet and outlet of the motor. If the disconnection is not timely, the above-mentioned fault phenomenon will occur.
