Submersible pump maintenance

Submersible Pump Maintenance: Maintenance Step 1: 500V shake table to detect submersible pump or sewage pump insulation resistance is more than 0.25MΩ, or should be diverted submersible pump or sewage pump, the coil for drying. Maintenance Step 2: Check whether the sealing ring has aged, it should be replaced if it is aging. Repair step three: Check the bearing wear, such as rotation when there is a significant abnormal sound or blocking phenomenon, you should replace the same model with the specifications of the bearing. Maintenance Step 4: Clean the submersible pump, sewage pump housing, such as serious corrosion should be in the surface after no paint again. Maintenance step five: Check the submersible pump, sewage pump connected to the hose is solid, such as relaxation should be tightened. Tighten the submersible pump, drain all the nuts on the pump. Submersible pump maintenance precautions: submersible pump in the demolition before and after the end cover should be marked with the base seat mark. In order to repair the assembly as it is, it will not cause assembly errors caused by the shaft is not the heart; in the removal of the submersible pump impeller and bushings and other components, it should be noted that must not hard hit hard impulse, available thermal expansion principle, heating edge Tap or use "Rama" and other tools to remove. Winding burn should be analyzed for reasons (overload, pump, lack of phase, leakage leakage short circuit, etc.), remove the motor windings, do not make the silicon steel tilt shift and burr and other phenomena, so as not to knock in the new winch assembly "bell mouth "Cause ground or short circuit fault. Rewound the new coil, the enameled wire and insulating paper must be selected regular manufacturers, due to the submersible pump motor heat level is generally E, B level. Must pay attention to its level of heat corresponding. Low insulation thickness should be sufficient, and to pad inserted in place. Winding off the assembly line, be careful not to scratch the stator core coil, but also avoid using crossed repeatedly crossed.

Culture Plates

Cell Culture plates provide the right environmental surface to cultivate microorganisms. Choose from a variety of treated and untreated plates and dishes in multiwells or uniform flat bases. Some of the features include optically-clear for easily viewing cells, stacking beads for easier handling, and gamma sterilized and certified nonpyrogenic.

Product material: made of polystyrene
Product features: Each hole is marked with numbers and letters, which is easy to locate. One section of the plate cover has two bevel guides to prevent cross-contamination.
Features:
Easy to locate: alphanumeric labeling
Increased hole edges: reduces the risk of cross-contamination
Independent packaging: each culture plate is individually packaged
The tightly integrated hole cover can effectively prevent the contamination and evaporation loss of the medium during the cell culture process
Good stability: Innovative cover edge diversion design, which greatly improves the circulation and exchange of air in the plate
