The difference between flushing pump and backwashing pump
There are some differences between flushing pumps and backwashing pumps in terms of function, working principle and application field. The following is a detailed comparison of the two:
I. Definition and function
Flushing pump:
Flushing pump is a device based on physical principles, mainly used for cleaning mechanical equipment, pipes and containers, etc., to maintain the normal operation and production efficiency of the equipment.
It uses the power of the motor and the pumping action of the pump body to suck water or other liquids into the pump body and spray it out through the outlet pipe to achieve the purpose of cleaning.
Backwashing pump (also called backwashing pump):
Backwashing pump is a special water pump, mainly used for backwashing operation in water treatment systems.
It forms a reverse water flow by changing the rotation direction of the pump motor and the drainage direction of the pump impeller to achieve the effect of cleaning and flushing impurities such as sludge and silt. The backwashing pump can also inhale air, mix with water to form bubbles, and use the vortex effect to clean the dirt and particulate matter in the filter medium.
II. Working principle
Flushing pump:
The working principle of the flushing pump is relatively direct, usually including the centrifugal principle and the one-way principle.
The centrifugal principle uses the rotating motion of the rotor to push water to the outlet of the water pump, forming a high-speed water flow for cleaning.
The one-way principle is to draw water into the pump body along the direction of unidirectional flow, and then push the water out through the pump head to achieve cleaning.
Backwash water pump:
The working principle of the backwash water pump is more complicated. It combines the two methods of water flow reversal and bubble cleaning.
When the backwash water pump is started, the water pump will suck in air while sucking water to form a water-gas mixture. When this mixture flows through the filter medium, the bubbles generated will cause the filter medium to vibrate and peel off, thereby cleaning the dirt and particles in it.
3. Application field
Flushing water pump:
Flushing water pumps are widely used in various occasions that need to be cleaned, such as cleaning of mechanical equipment, pipelines, containers, etc.
In the field of hygiene, such as hospitals, laboratories and food production plants, flushing water pumps also play an important role to ensure people's health and safety.
Backwash water pump:
Backwash water pumps are mainly used in water treatment systems, such as backwashing operations of filters, reverse osmosis systems and other equipment.
It is widely used in sewage treatment, industrial treatment, petrochemical, chemical engineering, pharmaceutical, food and beverage, biomedicine, shipbuilding and other fields. In sewage treatment, the role of the backwash pump is to ensure the normal operation of the treatment system and reduce pollution to the environment.
