Hydraulic Core Drilling Rigs / Geotechnical Exploration Small Water Well Drilling Rig Machine
Bore hole water well drilling machine is a kind of widely used portable drill machine. Water well drilling rig is suitable for drilling water well, geological survey, geological core drilling, small grouting holes, blasting holes of railway, water conservancy, bridges, dam foundation and other buildings. According to different strata, it drills by choosing different bits, such as, diamond composite films and alloy.

1. It improves drilling efficiency and reduces labor intensity with hydraulic automatic feeding mechanism
2. It can be achieved without stopping to change rods, easy to operate, safe and reliable with ball clip holding mechanism or hydraulic chuck.
3. It has hole bottom pressure gauge to be easy to master the situation in the hole
4.It also has advantage of compact structure,concentrated handle, small footprint, light weight, strong decomposition, easy to move. It can be operated in plains and mountain areas.
Sequence valve common faults and treatment methods
Failure Analysis (1) always out of oil, can not afford the role of a sequential valve (1) the spool stuck in the open position (such as poor geometric accuracy, the gap is too small; spring bending, fracture; 2) check valve in the open position stuck (such as the poor geometric accuracy, the gap is too small; spring bending, fracture; oil dirty) (3) check valve seal poor (such as poor geometric accuracy) (4) Spring breakage (5) pressure regulator spring drain (6) without cone valve or steel ball (1) repair, to meet the requirements of the gap, and to move the spool flexible; check the oil, if not meet the requirements should be filtered or replaced ; Check the oil quality, if not meet the requirements should be filtered or replaced; Replace the spring (3) Repair, so that the one-way valve seal is good (4) Replacing spring (5) Replenishing spring (6) Replenishment (2) Always out of oil, can not afford sequence valve action (1) Blocking of spool in closed position (eg poor geometry accuracy; Dirty) (2) control the flow of oil is not smooth (such as (3) remote control pressure is insufficient, or the bottom cover of the junction of the serious oil leakage (4) leading to the pressure regulating valve on the oil orifice of the orifice is blocked (5 (6) Adjustment spring too hard, or the pressure is adjusted too high (1) Repair, so that the spool movement flexibility, replace the spring; filter or replace the fluid (2 ) To clean or replace the pipe, filter or replace the oil (3) to increase the control pressure, tighten the end cap screws and force it evenly (4) cleaning (5) the drain pipe can not be connected to the oil return pipe, Fuel tank (6) replace the spring, adjust the pressure (3) set the pressure value does not meet the requirements (1) adjust the pressure spring is not properly adjusted (2) the lateral deformation of the pressure spring, the maximum pressure can not adjust to (3) (1) Re-adjust the required pressure (2) Replace the spring (3) Check the slide valve with the clearance, repair, so that the slide valve flexible; filter or replace the oil (4) Vibration and noise Oil resistance (back pressure) is too high (2) Oil temperature is too high (1) Reduce back to oil Resistance (2) control the oil temperature in the specified range (E) one-way sequence valve reverse can not return to the oil check valve stuck open do not open the check valve fault phenomenon analysis of the reasons to eliminate (a) always out of oil, can not afford Sequence valve action (1) spool in the open position stuck (such as poor geometric accuracy, the gap is too small; spring bending, fracture; oil dirty) (2) check valve in the open position stuck (such as geometric accuracy Poor, clearance is too small; spring bending, fracture; oil dirty) (3) check valve seal poor (such as poor geometric accuracy) (4) pressure regulating spring break Check the oil quality, if not meet the requirements should be filtered or replaced; replacement spring (2) repair, to meet the requirements of the gap, and to meet the requirements of the clearance and make the valve core flexible; Check the oil quality, if not meet the requirements should be filtered or replaced; Replacement spring (3) Repair, Check valve seal is good (4) Change the spring (5) Replace the spring (6) Make up Equipment (two) always out of oil, can not afford the role of sequence valve ( (1) the spool in the closed position stuck (such as poor geometric accuracy; spring bending; dirty oil) (2) control the flow of oil is not smooth (such as damping the orifice blocked, 3) Remote control pressure is insufficient, or the oil leakage at the junction of the lower cover is serious (4) The orifice leading to the pressure regulating valve oil line is blocked (5) The back pressure in the oil drain pipe is too high to make the valve slide ) Adjust the spring is too hard, or the pressure is too high (1) repair, the slide valve flexible movement, replace the spring; filter or replace oil (2) clean or replace the pipe, filter or replace the oil (3) , Tighten the end cap screws and make it even force (4) cleaning (5) the drain pipe can not be connected to the oil return pipe should be separately connected back to the fuel tank (6) to replace the spring, adjust the pressure (c) Does not meet the requirements (1) regulator spring adjustment is not appropriate (2) regulator spring lateral deformation, the maximum pressure can not go up (3) slide valve stuck, difficult to move (1) readjust the required pressure (2) (3) Check the slide valve with the gap, repair, so that the valve slide movement Ling ; Filter or replace the oil (four) vibration and noise (1) back to the oil resistance (back pressure) is too high (2) the oil temperature is too high (1) reduce the oil return resistance (2) control the oil temperature within the specified range ) One-way sequence valve reverse can not return check valve stuck open check valve
