1. Equipment Overview

The EH oil main pump 02-334632 is the core equipment in the fire-resistant fuel system, and its main function is to discharge and absorb oil. Under standard configuration, the fire resistant oil system of the power plant adopts two sets of EH oil main pump 02-334632 (fire resistant oil main pump) arranged in parallel under the oil tank, independent of each other and as backup for each other. Each pump is equipped with a filter element at the suction port of the fuel tank to filter the fire-resistant oil and ensure the cleanliness of the EH oil entering the pump.

2. EH oil main pump 02-334632 Main Performance Parameters

The geometric displacement of the EH oil main pump 02-334632 is 98.3cm3/r, with clockwise needle shaft rotation, suitable for open circuit plunger pumps. This pump has a fast response speed and can meet different performance requirements, suitable for hydraulic circuits.

3. Troubleshooting and Solutions

During daily operation, the EH oil main pump 02-334632 may experience increased noise. To address this issue, the following reasons can be used to troubleshoot it:

(1) Inlet pipeline leakage: Check and replace the seal.

(2) Leakage of shaft end seal: Replace the shaft end seal.

(3) Low oil flow: Readjust the pump flow and pressure adjustment device.

(4) The drain pipe is above the liquid level: increase the liquid level.

(5) Main pipe leakage: eliminate leakage.

(6) The inlet filter element has a gas gathering effect: check if the inlet door is fully open and clean the filter element.

4. Maintenance and management measures

To ensure the normal operation of the EH oil main pump 02-334632, the following maintenance and management measures should be carried out regularly:

(1) Regularly check the operation status of the oil pump, monitor indicators such as noise and vibration, and ensure that the pump operates within the normal range.

(2). Check the pump inlet filter screen to ensure the filtration effect and prevent blockage of the oil circuit.

(3) Regularly replace the seals to prevent leakage.

(4) Regularly clean the inside of the pump to prevent impurities from accumulating.

(5) Regularly check the shaft end seal to ensure the sealing effect.

The EH oil main pump 02-334632 plays a crucial role in the fire resistant oil system of power plants. By maintaining and managing the EH oil pump, the normal operation of the pump can be ensured, thereby ensuring the reliability of the fire resistant oil system in the power plant. At the same time, for possible faults that may occur during pump operation, timely inspection and troubleshooting should be carried out to ensure stable system operation. Only by doing a good job in pump maintenance and management can safe and reliable fire-resistant oil system be provided for power plants.
