Maintenance and pre installation inspection of gear oil pump equipment

【1】 The maintenance of chemical circular arc gear oil pump equipment is usually based on the operating time of the equipment. Before carrying out maintenance, the equipment should be carefully inspected as follows:

Firstly, check the appearance of the equipment, especially the gear components and exposed parts, to ensure that the equipment does not rust or remains clean

Secondly, check the equipment gears and confirm in detail whether the components are loose. Also, carefully inspect the shafts, impellers, bearings, etc. to see if there are any signs of wear

If an abnormality is detected, the cause should be analyzed and immediate measures should be taken to repair and maintain it

Thirdly, carefully check the other conditions of the arc pump and supporting equipment, such as the oil filter not being blocked, the lubricating grease meeting the corresponding standards, and replenish lubricating oil according to the current situation of the oil tank. Fourthly, inspect the electrical system. It is necessary to check the grounding and insulation of the electrical system, as well as the vibration, temperature, and other issues of the motor

[2] Inspection before installation of circular arc pump

To achieve good sealing effect of circular arc pump, relevant inspection work needs to be done before installing the mechanical sealing device of the chemical pump.

. Especially, it is important to inspect the friction end faces of the dynamic and static rings of the circular arc pump, as this is the key to the good performance of the mechanical sealing device. When conducting pre installation inspection on the dynamic and static rings of the circular arc pump, the staff can measure the end face of the dynamic and static rings using a caliper to see if they meet the corresponding size standards and if their surface flatness is even. In general, the surface flatness of the standard dynamic and static ring end face shaft or shaft sleeve should be kept below 0.32Lm, and the cleaning work of each sealing component should be done well, and its integrity should be carefully inspected. Once it is found that the friction end face of the circular arc pump is damaged or the plane is not flat enough, it should be replaced and repaired in a timely manner
