General Instructions:

To maintain the heating pump in a working condition, operational personnel must conduct technical maintenance.

The heating pump must be serviced by qualified personnel who have undergone training in the operation of electric pump installations and adhere to safety regulations.

Safety Measures:

There should be no foreign objects near the heating pump that obstruct monitoring of its operation.

Technical maintenance of the operating unit should, when necessary, be carried out using personal protective equipment for hearing protection.

Other safety requirements according to the Operation Manual.

Procedure for Technical Maintenance:

During the intended use of the heating pump, operational personnel must conduct its technical maintenance with periodic checks (not less than once per shift).

During operation, the servicing personnel must keep a logbook recording the pump's start and stop times, instrument readings, and any malfunctions.

Operating the heating pump outside its working range may cause overload, posing a danger to personnel and equipment damage.

Periodic checks of the operating heating pump should include external inspection of the unit with:

  • Without measurement tools:
  • Tightness of detachable connections of the pump body and auxiliary pipelines;
  • Noise level, vibration of pump bearing housings, and motor;
  • Leakage through pump shaft seals (dripping or thin stream);
  • Functionality of control and measuring instruments;
  • With the use of standard measuring tools and registration in the logbook:
  • Bearing temperatures of the pump and motor.
  • Pump operation parameters (delivery, inlet and outlet pressures);

Engine operating parameters - according to its operational documentation.

Checks should be performed immediately after startup and every 8 hours of continuous operation.

Continuous monitoring of the bearing condition is necessary. The established temperature of the bearing housing should not exceed 65°C.

Periodically observe the lubricating rings; they should rotate freely with the pump shaft.

Monitor the oil level in the bearings according to the level indicator. Perform the first oil change in the bearings after 200-300 hours of operation, and subsequent lubricant changes every 1000-1200 hours or earlier if contaminated.

Periodically, every 2000 hours of operation, monitor the condition of the rubber bushings of the flexible bush-finger coupling.

When assembling the heating pump with a gear coupling, monitor its condition. If there are traces of oil on the gear coupling, stop the pump, check the tightness of the sealing joints and oil filling holes. Add oil if necessary. Lubricant change should be carried out every 1000 hours of operation while monitoring the degree of wear of the coupling and alignment of the unit.

Periodically, every 2000-3000 hours of operation of the heating pump, it is necessary to check the condition and clearances in the seals of the impellers.

During the operation of the heating pump, it is necessary to control the tightening of the cap nuts on the pump body connector and the flange joint nuts.

It is necessary to record the total operating time of the heating pump from the time of commissioning after installation or regular overhaul. Keeping track of the operating time is necessary to determine the timing for pump repair and lubricant replacement.

Engine maintenance should be carried out in accordance with its operational documentation.
