Dissolved oxygen electrode maintenance precautions
Tractor Type Water Well Drilling Rig
The advantages of 2021 tractor water well drill rig:
The repeated use of the tube and protecting in drilling to the corresponding position Into the hole, we also need to pull it up, in order to make its use more convenient, portable tube drawing device was designed, can use the quick connector directly connected to drill, drill to to pull power clamp, this design method, not only reduce the cost of pig pull, increases the flexibility and convenience.

Dissolved oxygen electrode maintenance notes:
(1) The electrode of the dissolved oxygen meter should be cleaned every 1 to 2 weeks. If there is any contaminant on the diaphragm, it will cause measurement error. Care should be taken when cleaning, taking care not to damage the diaphragm. Dissolve the dissolved oxygen electrode in clean water. If the dirt cannot be washed out, use a soft cloth or cotton cloth to scrub it carefully.
(2) The zero point and span of the dissolved oxygen meter electrode should be recalibrated from February to March.
(3) Regeneration of the dissolved oxygen electrode is performed approximately once every year. When the measurement range is not adjusted, the dissolved oxygen electrode needs to be regenerated. Electrode regeneration includes changing the internal electrolyte, replacing the diaphragm, and cleaning the silver electrode. If the silver electrode is observed to be oxidized, it can be polished with fine sandpaper.
(4) If the dissolved oxygen meter electrode is found to leak during use, the electrolyte must be replaced.
With reference to the above, the use of the dissolved oxygen meter is not only used correctly, but also important in terms of maintenance. Many customers have problems after they have bought it back. Most technicians are picking up electrodes. When I accidentally bumped the membrane head and broke the film, it caused too much negotiation between the customer and the supplier and the rework of the turnover. Therefore, when using it, you can be careful and avoid many things. Trouble.
Drill in tractor diesel engine as power of drilling, drilling rig working parts and tractor integrated into an organic whole, tractor is drill, and transport machinery, is also the motivation of drilling rig, can mount Air Compressor and other transportation means, save the transport vehicle investment, lower cost, work more convenient;
The drill rig designed the Mud Pump, which really realized the water and gas. It is very difficult to drill for a gas drill. It is an ideal choice for you. The design of the mud pump is optional. We will provide it only when you need it.
