If the ry heat transfer oil pump is in service, it is best to look at the manufacturer's maintenance manual and the general assembly drawing to see what special places need attention. Ry heat transfer oil pump maintenance process should pay attention to the aspect of the ry heat transfer oil pump maintenance If you have the conditions, it is best to look at the manufacturer's maintenance manual and the general assembly drawing to see what special places need to pay attention. Metal Sheet Laser Cutting Machine is professional in cutting varies metal sheets. Such as stainless steel, carbon steel, mild steel, iron, galvanized steel, titanium steel, silicon steel, brass, aluminum, titanium alloy, brass, copper, silver, gold, etc.
Metal Sheet Laser Cutting Machine advantage:
1. Efficient and stable programming and control system, easy to learn and user-friendly, compatible with a variety of CAD drawing formats, intelligent nesting to save costs, automatic cutting path matching to save processing time; 2. Metal Sheet Laser Cutting Machine with low energy consumption and low cost of use; high equipment stability, simple and convenient maintenance, and low maintenance cost;
1. When disintegrating:
1. Before the thrust bearing is removed, the balance plate gap should be measured by the dial gauge, and the record should be made;
2. When the RY heat transfer oil pump is disassembled, the parts must be marked according to the original assembly order. Botaibang is not to be confused or misplaced when loading.
3. Small pieces (such as keys) that are inconvenient to be marked can be placed together with the impeller or vane (middle section) of the same class.
4. When disassembling, you can intuitively feel if there are abnormal parts, such as loose fitting.
2. Parts maintenance:
1. Visually check whether the surface of each part is normal, and each mating surface must be scratch-free, rust-free, etc.;
2. Whether the tolerance of the critical matching part of the measuring tool is qualified;
3. Whether the clearance between the impeller seal ring, the casing seal ring, the vane seal ring, the interstage bushing, etc. is within the tolerance range, and the wear is too large and needs to be replaced;
4. Check if the bearing is in good condition;
5. All seals and gaskets are preferably replaced with new ones;
Three. Reloading:
1. Install the rotor first and re-run the dynamic balance test;
2. Reload the parts in the reverse order of the pump removal. Pay attention to the gap value at each seal ring when reloading, to ensure that there is no error;
3. The total number of rotors should be measured before installing the balance plate;
4. After loading the balance plate, measure the rotor half string.
5. The heat transfer oil pump and the total string quantity and half string quantity required on the general assembly drawing of the manufacturer shall basically meet the drawing requirements. In general, the half string amount is about half of the total string amount.
6. Evenly tighten the main bolts, pay attention to the angle;
7. A piece of dial indicator is sucked on the shaft, and the rotating shaft is used to mark the balance plate. The tolerance is not required to exceed 0.06 according to the requirements of the drawings;
8. When installing the thrust bearing, pay attention to adjust the clearance of the balance disc. The balance disc clearance should be adjusted to the drawing requirements by using the adjusting ring in front of the bearing.
