How do you maintain a water pump?

How Should Water Pumps Be Serviced & Maintained

  1. Check the physical condition of the system to ensure it is secure and undamaged.
  2. Specifically examine the condition of the pump including its impeller, seals, bearings, valves and volute.
  3. Assess the condition of pipework for wear or damage.
  4. Ensure sump and floats are clean.

What maintenance task should be carried out on pumps?

Routine maintenance (Can be made during pump operation) Lubricate the bearings. Inspect suction and discharge flanges for any leak. Inspect pump casing for any unusual damage signs. Inspect the seal.

How can we protect centrifugal pump?

One way of ensuring adequate flow resistance at the pump discharge is by placing a throttle valve or an orifice immediately downstream of the pump discharge. Also, a properly designed piping system is critical to ensuring a pump’s safety from runout.

What are the different parts of water pump that need to be maintained?

Only a few parts on most pumps need maintenance. Centrifugal pumps need maintenance performed on the bearings, seals, and drive systems. Valves will eventually wear….Mechanical Seals

  • No leakage of the liquid being pumped.
  • Elimination of shaft or sleeve wear.
  • Reduced friction and power losses.
  • Reduced maintenance.

What are the activities performed during periodic maintenance?

Periodic maintenance is a strategy that requires maintenance tasks to be performed at set time intervals while the vehicle is operational. Similar to scheduled maintenance, periodic maintenance activities are planned ahead of time and are performed with or without signs of deterioration.

Which of the following are to be checked while carrying out the overhaul of a pump?

CHECK THE CONDITION OF SLEEVE AND CHECK FOR GROOVES AND MARKINGS WHERE MECHANICAL SEAL IS FIXED. IF SLEEVE IS HAVING ALOT OF GROOVES THEN SLEEVE TO BE REPLACED. CLEAN THE IMPELLER, KEY, SHAFT AND TOP COVER. CHECK THE IMPELLER FOR CORROSION, PITTING, CAVITATION AND WEAR.

What protects the impeller of pumps from damage?

Casing: A casing can be explained as a shell, cover or a housing which protects and supports most of the components. In pumps, the casing is basically used to seal it to prevent leakage and sometimes retain pressure.

How centrifugal pumps are protected from the conditions of dead heading and pump runout?

One method for protecting the pump from running dead-headed is to provide a recirculation line from the pump discharge line upstream of the discharge valve, back to the pump’s supply source. The recirculation line should be sized to allow enough flow through the pump to prevent overheating and damage to the pump.

How do water pumps work?

These pumps use a piston or a turbine to produce a partial vacuum to draw the water out of the well. The same piston or turbine is then used to increase the pressure of the water. This pressure, in turn, pushes the water out of the pump and down the pipes.

What are main components of pumps?

The main components in a pump are the casing, impeller, backing plate, shaft and shaft seal, and the motor adapter.

What is the working principle of centrifugal pump?

The working principle of centrifugal pump can be found in many machines, a leaf blower, water pump, hair dryer….many of these small or large machines are applying the principle of the centrifugal force, when a wheel is spinning, the center will suck the air or water in and the centrifugal force will sling the air or water out from the edge.

What is the working principle of an impeller in a pump?

The impeller is the rotating part of the pump and is circular in shape with backward curved vanes. The rotation of the impeller exerts a centrifugal force on the fluid due to which the fluid is thrown outward. Due to this kinetic energy is imparted to the fluid.
