First, the control cabinet maintenance:
1) Maintain indoor ventilation and drying.
2) Regularly check the control cabinet to indicate whether there is power supply, the voltage is 380V.
3) Regular power cut Check the control cabinet components are normal, the wire is loose.
4) regularly check whether the pipeline leaks, leaking.
Second, the pump maintenance:
1) The inlet pipe must be filled with liquid, and the pump should not be allowed to operate for a long time under the condition of gas turbidity.
2) Regularly check the motor current value, must not exceed the motor rated current.
3) Long-term operation of the pump, due to mechanical wear, the unit noise and vibration should be stopped and checked, if necessary, replace the vulnerable parts and bearings, unit maintenance is generally one year.
4) Mechanical seal lubrication should be clean without solid particles. Mechanical seal dry work is strictly prohibited.
5) Before starting the pump should be circling a few laps, so as not to suddenly start causing graphite rupture damage. Seal leakage allow 3 drops / min, otherwise it should be checked.

Product Description
Brief Introductions of Reaming Shells
Reaming shell is used to couple the drill bit with the core barrel. It is suitable for use on all conventional and wireline core barrel. This product is mainly designed to ream the hole to the standard diameter. It can keep the stability of the core barrel. When the old bit is replaced by the new one, reaming shell can also provide sufficient clearance for the new bit. It can also help to resist the abrasion of the core barrel. This type of diamond tool is physically longer than the standard type. So for the compensation of the difference in reaming shell length, an appropriate inner tube extension is necessary to be used.
Ranging from broken and abrasive to consolidated and non-abrasive formations, reaming shells are all suitable to use.
Features of Reaming Shells
1) Acts as a stabilizer for drill bit.
2) Be set with natural or synthetic diamond.
Our reaming shells enjoy the best quality and most special design in the industry. With several different types, we try our best to satisfy any of your requirements.
