Description

XU1000 type core drilling machine integrates the advantages of spindle type drilling rigs. It can be used in metal or nonmetal solid deposit exploitation. This core drilling rig plays an un-replaceable role in the fields of geology, hydrology, metallurgy and coal field exploitations. This core drilling machine has water brake and has a normally-open type clutch mechanism. XU1000 type core drilling machine integrates the advantages of spindle type drilling rigs.

Features and Advantages

1. This core drilling rig is equipped with conventional type rotary unit. It is suitable for small-diameter hole drilling with diamond bits and large hole drilling with diamond bits.
2. This core drilling machine is capable of drilling both vertical holes and inclined holes.
3. The chucks of this drill rig have large clamping force and the clips have long service life.
4. One control handle can realize the conversions among eight forward and reverse speeds in one revolution.
5. The water brake used in the core drilling machine helps to reduce the operator’s workload.
6. Duplicate gear oil pump can reduce oil temperature with rational power utilization.
7. The oil-dip type clutch can be started smoothly. It has brake gear.
8. The sliding wheel of the winch is well sealed. The winch has great hoisting capacity.
9. The entire core drilling machine is very stable and easy to disassemble.
10. This core drilling rig has absorbed the advantages of similar rigs at home and abroad. It features high strength, compact structure, rational layout, stable operation and centralized control.
11. The core drilling machine has a complete range of rotating speed.

1. Pressurized drilling operation. Put the handle of the operating valve to ‘drilling’. The feed control valve is in open state. Clients can determine the pressure value according to the pressure condition of hole bottom.
2. Reduced pressure drilling operation. Put operating valve handle to ‘hoist’. Reduce the pressure properly according to the amount of drill rig weight which exceeds the needed pressure at hole bottom. Adjust feed control valve according to feeding speed.
3. Drilling operation with self weight. This method is used when the weight of the core drilling machine and the needed pressure are equal all close. In the drilling process, operator should put the operating handle to ‘hoist’ or ‘decline’ and set the pressure of overflow valve to zero. Operator should adjust feed control valve to make the spindle drop smoothly.

Use and Maintenance

Clients should do some inspections before starting up the core drilling machine.
1. Connections of all components should be firm and reliable. The mating face should be clean.
2. Clients should add lubrication oil to lubrication points and check the liquid level in the oil box.
3. All braking parts of the core drilling machine should be working reliably.
4. The clutch of the core drill machine should be adjusted to a suitable state.
5. Clients can use turning gear to observe the parts and to find out whether they are moving correctly and reliably.

Clients should maintain the core drilling machine regularly.
1. Workers should check every fastening part and clean all mating faces in each shift. The core drilling rig should be lubricated according to the lubrication form.
2. Clutch and hand-operated oil pump should be checked every week.
3. Clients should clean the oil box and filter the oil every month. Hydraulic oil should also be checked. Please consult the manual of the core drilling machine for detailed information.

Packaging & Delivery

This core drilling rig could be delivered in 30 days normally.
