AY centrifugal oil pump-Global supplier

1、 Product Overview

The AY oil pump series is an improved and redesigned version of the original Y-shaped oil pump series.

2、 Product Features

1. The bearing body components have replaced the original 35, 50, and 60 bearing bodies with 45, 55, and 70 bearing bodies, respectively, improving reliability;

2. The hydraulic flow section adopts an energy-saving hydraulic model, which improves the efficiency by an average of 5-8 percentage points compared to the original Y-shaped oil pump;

3. To maintain continuity, the structural type, installation dimensions, and performance parameter range of AY type oil pump are kept the same as those of Y-shaped oil pump, which facilitates the updating and transformation of old products.

4. The degree of standardization of components is high, and standard parts are shared by several series of products.

5. The material selection is refined, mainly consisting of Class II and III materials. The bearing body and other parts are increased to two types: cast steel and cast iron, providing favorable conditions for cold regions, outdoor use, and marine use.

6. There are three types of bearings: air-cooled, fan cooled, and water-cooled, which are selected according to the different operating temperatures of the pump. Among them, fan cooling is particularly suitable for areas with water shortage or poor water quality.

3、 Main purpose

AY type oil pump can be used to transport petroleum, liquefied petroleum gas and other media without solid particles in petroleum refining, petrochemical and chemical industries, and other places.

In order to easily remove components such as impellers, shafts, bearings, and shaft seals without dismantling the suction or discharge pipelines during pump maintenance, AY type oil pumps use flexible diaphragm type extended coupling components.

1. Cooling water is used to cool the shaft seal chamber, bearings, or pump supports according to temperature and usage requirements. The recommended water volume for each pipeline is 0.3-0.7m3/h, with a pressure of 0.2-0.3MPa.

2. Sealed flushing varies depending on the medium being transported by the pump, as well as its working conditions such as temperature and pressure. The sealing liquid volume for each pump chamber is shown in the table below, and can be supplied internally or externally.

Technical Parameter

Flow Q: 2.5-600m3/h

Head H: 30-330m

Speed n: 1450-2900r/min

install

The height, length, and diameter of the pump suction pipe should meet the design requirements and ensure that it does not exceed the allowable cavitation allowance of the pump during operation.

2. The suction and protrusion pipes should have pipe racks, and the pump body is not allowed to bear the external load of the pipeline.

3. The suction pipe should be short and straight, and the diameter of the pipe should be 1-2 degrees larger than the diameter of the pump suction port. The eccentric contraction of the variable diameter pipe should be used for connection, and the pump suction pipe should be made with a well crafted bending radius.

4. Correct the concentricity between the pump shaft and the prime mover. The allowable deviation on the outer circle of the two half couplings is ≤ 0.08mm, and the end face deviation is ≤ 0.05mm.

5. After installing the pipeline and determining the direction of rotation of the prime mover, reinstall the coupling.

Maintenance

Maintenance content:

1. Check the wear of components such as the shell sealing ring, impeller sealing ring, throat liner, shaft sleeve, guide vane sleeve, impeller, shaft sleeve, and dynamic and static rings of the mechanical seal.

2. Clean the dirt and blockages in the cooling water, sealing oil pipelines, and water-cooled chambers.

3. Check and adjust the bending of the shaft and the jumping of the rotor.

4. Check for defects and scratches in the O-ring seal, shaft sleeve gasket, pump cover gasket, and mechanical seal cover gasket

5. Verify the concentricity of the two half couplings

Maintenance requirements

1. Double the gap between the sealing rings (resulting in decreased efficiency and increased power) or replace them if the current is too high.

2. There are grooves on the outer surface of the packing shaft sleeve, and scratches on the sealing surfaces of the dynamic and static rings of the mechanical seal, especially radial scratches. Mild scratches should be repaired by grinding, and severe scratches should be replaced.

Maintenance and upkeep

1. Regularly check the heating condition of the bearings. The temperature of the rolling bearings should not exceed 80 ℃, and the temperature of the rolling bearing parts should not exceed 65 ℃.

2. Check the oil cup every 8 hours during shift changes to ensure the oil level is normal.

3. It is recommended to drain and rinse the oil every six months, and then add new oil. Generally, this should be done in spring and autumn. For sites in humid, desert areas, with significant climate change, and outdoors, frequent oil changes are also necessary.

4. For the backup pump on the device, the rotor components should be rotated regularly. It is recommended to rotate once a week, around 360 °+90 ° each time, to prevent deformation and maintain the lubricating oil film of the bearings.

5. For the high-temperature standby pump on the device, it is also necessary to maintain a certain temperature for standby.
