Maintenance of gear oil pump

Core Tip: When disassembling the gear oil pump, each part should be preserved. Special attention should be paid to the explosion-proof surface of the explosion-proof parts. The insulation should not be damaged, including the insulating gasket and casing. If it is damaged, it must be replaced with the new one. Parts shall not be replaced with substitute materials that are lower than the performance of the raw materials or parts that do not conform to the original specifications.

Introduce the maintenance of some gear oil pumps should pay attention to:

1. Save each part and exchange the same parts. When disassembling the gear oil pump, each part should be preserved. Pay special attention to the explosion-proof surface of the explosion-proof parts, which can not damage the wool, including the insulating gasket and casing. For damage, the same new parts must be replaced. Substitute materials that are lower than the performance of the raw materials or parts that do not conform to the original specifications shall not be used. All parts shall be assembled in the original position during assembly and shall not be missed.

2, often fatliquoring, electric drum pump for high-speed operation, grease is easy to volatilize, so the lubrication at the bearing must be kept clean, and pay attention to add.

3, pay attention to save the electric pump should be placed in a dry, clean and non-corrosive atmosphere.

4, gear oil pump often check maintenance, electric oil drum pump should be checked frequently, maintenance, must check the power cord: internal wiring, plug, switch is good, insulation resistance is normal, brush tail seat is loose, commutator and brush Good contact, whether the armature windings the stator windings are suitable for interrupting the road, whether the bearings and rotating parts are damaged, etc.

5, gear oil pump pay attention to insulation resistance, long-term use of electric pumping pump used or used in humid environment, the insulation resistance of the winding must be measured with a 500 volt megger before use. If the insulation resistance between the winding and the motor casing is less than 7 megohms, the winding must be dried.

Concerned about surprises

Flange mainly used for connecting two pipes, used at  pipe end; also connection between the two devices. Steel Flange materials can be divided into: low carbon steel flanges, mid-carbon steel flanges , high carbon steel flanges, alloy steel flanges. Steel flange has a  high strength,good toughness,and high resistance to corrosion,high pressure and temperature, more excellent sealing performance, a wide usage range. Steel flange is widely used in petroleum, chemical, food, dairy, pharmaceutical, machinery manufacturing, sewage treatment, municipal water supply pipelines, military and medical industries

Flange containing integral flange (IF), threaded flange (Th), plate  flange (PL), Weld Neck Flange (WN), slip on  flange (SO), socket Weld Flange (SW), loose flange (PJ / SE), flat welding ring loose flange (PJ / RJ), Blind Flange  (BL)
