There is no medium or transmitted medium flow relatively small

If the heat flow in the heating system is small or the flow is not flowing, the main shaft of the circulating pump and the stable bearings will cause dry grinding, and the bearings will be shattered. The circulating water pump is cooled and lubricated by the pumping medium to the bearing. If there is no sufficient water flow, it will be damaged due to the sliding bearings without media. The solution is to fill the hot water in the heating system.

The leaf wheel is stuck

The reason for the cycle pump is not circulated is that the impeller is stuck. When the impeller is stuck, the circulating pump cannot work properly. There will be more scale or foreign matter in the heating system. If it is blocked by scale and foreign objects, If the cycle pump will not be circulated. The solution is to contact the maintenance personnel to disassemble the circulating water pump, clean up the internal debris, and remove the entangled wounds on the blade. You can also add a lubricant to the circular pump. In order to prevent the circulating pump from being stuck, a filter can be set in front of the circulating pump, which can prevent foreign objects from blocking the circulating pump.

Motor damage

It is likely that there is a problem with the circulating pump motor, and the circulating pump motor will not be circulated after no motivation. The damage to the motor is likely to be aging, or it may be a normal motor to work at high temperature. The solution is to replace the aging motor or replace the burned motor.

The difference between the booster pump and the circulating pump

Difference

Steering pump: It is literally understood as a pump for the pressure to give the conveyor medium. The pipeline supercharged pump is suitable for high -rise building supercharged, water heater supercharged, high -rise building supercharged, and bathrooms.

Circular pump: The raising of the circulating water pump is relatively low, which can be used to overcome the pressure of the circulatory system. The circulating pump generally refers to the role of the pump, which generally refers to the pump pumping reaction, absorption, separation, and absorption of the pump in the device.

Different working principles

Working principle of pressure -booster pump: You can first fill the liquid in the booster pump and start the pump. The leaf wheels will rotate quickly. The leaves of the leaves will drive the liquid to rotate together. When the room flows out, this force will work for liquid work to ensure that the liquid gets energy and leave the leaf wheel.

The working principle of circulating pump: It is used to circulate water. For example, the thermal water in the water heating tube is used to use the circulating pump for recycling.

Different stress and weakness

The booster pump can solve the situation of excessive water pressure, and the pressure -booster pump belongs to a low -pressure pump. The booster pump can increase the pressure with the help of centrifugal force. The pressure of the circulating pump is higher than that of the booster pump, which can drive the heating system for recycling.

Different installation location

The booster pump is generally installed in the water inlet pipe. After cutting the raw water pipe for a section, the pump and tandem pipe can be connected. The circulating pump should be installed on the water -return pipe, which can increase the pressure of the system. After cutting the water pipe for a while, the booster pump can connect the pipes in series.
