Product details

What does the flow coefficient in the Hall induction mini dc water pump refer to?

The flow coefficient of the Hall induction mini water pump refers to the ability of the water pump to pump liquid from a low place to a high place per unit time, which is usually expressed as "flow rate per unit head". In other words, the flow coefficient is the ratio of the pump's flow rate to its head. This coefficient can be used to evaluate the performance of the water pump.

If the coefficient of flow is higher, it means that the pump can deliver more liquid at the same head. The calculation formula of flow coefficient is: flow coefficient = flow rate (L/min)/head (m).

What is the standard flow rate and lifespan of DSB413-B-HR dc diaphragm water pump?

The flow rate of the Hall induction small dc pump is 0.26±3%g. The "±3%g" here means that the error range of the flow rate is ±3% of the actual flow rate. That is, the actual flow rate may be 3% higher or lower than the nominal flow rate.

The life of the Hall induction mini dc pump is 500 hours. After starting and stopping, only the time on is counted. The work requires 30S on and 30S off.

How does the overheat protection function of the Hall induction mini dc liquid pump work?

The overheat protection function of the Hall induction mini dc pump is mainly realized through the thermistor. The thermistor is a special type of resistor whose resistance changes with temperature. In Hall induction water pumps, a thermistor is usually installed inside the motor to monitor the temperature of the motor. When the temperature of the motor is normal, the resistance of the thermistor is relatively large and the current in the circuit is small. But when the motor overheats, the resistance of the thermistor will decrease rapidly and the current in the circuit will increase, thus triggering the overheating protection circuit. The overheat protection circuit usually consists of a relay and a pair of heated contacts. When the current in the circuit exceeds the set value, the heating contact will act quickly to disconnect the relay, thus cutting off the power supply to the motor and stopping the work of the water pump. At the same time, the overheating protection circuit will also send out a warning signal through an indicator light or buzzer to remind the user that there is an overheating problem in the water pump.

Does the DSB413-B-HR Hall induction micro water pump have overheating protection function?

Currently our water pump does not have overheating protection function, but we can add this function to the water pump.

When the motor temperature of the Hall induction dc water pump is too high, the overheat protection function will be automatically triggered to stop the water pump to prevent damage to the motor due to overheating. The implementation of the overheat protection function varies with different models of water pumps, but it is usually implemented through built-in overheat protection circuits or components such as thermistors.

hall sensor pump application

A Hall sensor is a type of sensor that detects the presence of a magnetic field. In the context of a mini water pump, a Hall sensor can be used to monitor the flow of water.

When hall sensor mini dc electric pump is operating, the water flows through a pipe or a channel. By placing a Hall sensor near the pipe or channel, the sensor can detect the movement of water. This is done by utilizing a magnetic field generated by the water flow.

The Hall sensor consists of a small chip that contains a Hall effect sensor. When a magnetic field is present, the Hall effect sensor generates a voltage proportional to the strength of the magnetic field. This voltage can then be measured and used to determine the flow rate of the water.

By monitoring the output of the Hall sensor, it is possible to keep track of the flow rate of the water pump. This information can be used for various purposes, such as controlling the pump's speed, detecting any abnormalities in the flow, or providing feedback for system optimization.

Overall, using a Hall sensor to monitor the flow of a mini diaphragm pump can provide valuable information for efficient and reliable operation of the pump.
