1.HW-1000 type reverse circulation drilling machine,this drilling rig Is integrated with multiple functions as one of the rotary drilling rig,It embodies the new technology of a machine.Is an ideal pore forming machine,water well drilling machine Walking method has hydraulic walking type,Vehicle mounted, crawler type, Trailer type,Make the machine more use,The operation is more flexible, convenient and reliable.This machine is in the variable of formation.May at any time according to the formation change fast drilling method .In addition, The machine has four speeds.Therefore, this drilling rig machine is more suitable for sand, silt, clay, stone pebbles, gravel, and other weathered rock complex stratum construction.Is widely used in construction, bridges, water conservancy, water wells, electricity,telecommunications, engineering and other construction projects.

Two:the structure of drilling rig

HW-1000 type drilling machine is a positive and negative circulation drilling machine,By YD multi speed motor, reducer, positive, reverse circulation mud pumps, valves, hydraulic pump, cylinder, main hoist, vice winch, distribution box, drill frame, drill pipe, drill bit.
1 ,Drive motor is YD series of multi speed variable speed motor
2, reducer for the four shaft three gear reduction, can be used to transform the gear speed, divided into four kinds of speed.

Three, water well drilling rig working principle
1 the water well drilling rig  hydraulic system of the drilling machine is controlled by the multi way valve of the pressure pump through the pipeline, and it is required to be served on the executive body, so that it can complete the action.
2.The drilling machine reducer will power transmission is transmitted to the output shaft, drive drill and cyclotron motion, complete forward (clockwise) carry on the work of cutting and (reversal unloading the drill pipe) in normal drilling ban reversal (reversal will cause the drop of drill pipe, drill bit accident)
3.positive and reverse circulation driling rig operation:

3.1 in construction such as encountered strata or clear hole and need replacing the positive and reverse circulation, take the positive cycle, for example, hydraulic operation handle large mud pump pressure valve closed, start small 3pnl mud pump, mud through a pipeline, after pump, drill pipe, into the bottom of the bit, mud by water hold up along the pipeline flow into the mud pool. After precipitation of water into the 3PNL mud pump, the formation of circulation.

Four, drilling rig safety operating procedures
1 this water well drilling rig  machine operator must be trained, should be familiar with the operating mechanism and familiar with the safe operating procedures to operate on the machine.
2, before starting the water well drilling machine, should drilling rig and ancillary equipment were examined in particular should pay attention to check the windlass brake is flexible and reliable, whether the rope is broken wire breaking phenomenon, to be confirmed that the intact, start working.
3,field staff must wear insulated shoes, wear safety helmet.
4,When removing the drill pipe energy should be concentrated, pay attention to remove the foreign matter on the drill pipe thread, drill pipe joints a little oil, can reduce the occurrence of drill pipe damage and leakage.

Five, water well  drilling machine the use and maintenance of drilling rig

1.water well drilling machine found that the lack of oil should be added in time, regular replacement of oil to the host, hoist, pump oil.
2 .In the construction site, check the pump can not be reversed.
3 .work, should be at any time to monitor the instrument, to listen to the operation of the various parts of the sound, such as sudden abnormal sound, should be shut down inspection, whether the loosening of screws.
4. hydraulic handle operation, should first slow fast (depending on the location of the site). If the operation is too fast will damage the equipment and the risk of
5. The drilling speed according to the stratigraphic changes varies, depending on the pump reverse circulation of water (water flow, high, fast forward, a small amount of water to slow or stop). At the same time to control the proportion of mud, in the current range of rated current, and slowly drilling.
6 .often check whether the oil pipe and the joint oil leakage, the fuel tank is short of oil, such as the lack of oil cylinder crawling phenomenon.
7 drill rig, long time not to use, should be all the supporting legs of the oil cylinder to recover, or with anti rust oil package, prevent rust and damage.
8 well drilling depth of five thousand meters, should carry out maintenance and repair.

Six, drilling rig power distribution system

1. water drilling rig the distribution box is supporting equipment zfj-1500 rig for to the rated voltage 380V, frequency 80Hz, three-phase AC power supply.

2. well drilling machine Using conditions

A.air temperature not greater than 85%

B.sea level height of not more than 1000 meters

C. network voltage fluctuation is less than -5% of the +5%.

D.After the site power is connected, close the leakage protection switch, the control button can work normally (confirm the motor rotation direction)
