A water pump is a machine used to transport liquids or increase the pressure of liquids. For example, liquids that can be used for transportation include water, acid-base liquids, oil, and liquid metals, and mixtures of liquids and gases can also be transported using water pumps. The function of a water pump is to transfer the original mechanical energy or external energy to the liquid, gradually increasing the energy of the liquid.

Some cities use water pumps for waterlogging or drainage. When the water pipes in the city become blocked, we can use drainage pumps to quickly achieve rapid drainage. Some of the pumps used in industry are circulation pumps, and some boilers may use this type of pump body for operation. In our daily lives, there is also a type of booster pump. We hear its name as a machine that can increase pressure. Some homeowners living in high-rise buildings inevitably need to use water. When the water pressure is insufficient, the booster pump works. It can be installed in pipes at home to increase water pressure. When the faucet is turned on, the flow rate can be increased. A water pump can pump liquid from lower terrain to higher ground and use water to irrigate things.

When using a water pump, if a malfunction is found, even if it is a minor problem, it should be stopped from working. When the packing of the water pump shaft wears out, add it immediately. If it continues to be used, it may cause damage to the impeller due to excessive energy consumption of the motor. When using a water pump, if severe vibration is detected, stop using it immediately and check for faults to avoid permanent damage to the pump.
