It is an important link to improve the efficiency of the high temperature water pump to ensure the efficient operation of the pump. The efficiency of the pump is related to the design and manufacturing level of the pump, the operation of the pump and the management level of the pump. The technological transformation of water pump can be improved and improved from the following aspects.
The rationality of type selection of 1. check pumps
According to the performance of the pump and the pipeline system, the pump manufacturers check the working parameters of the pump in the design of the lift, the highest lift and the lowest lift. The pump is required to operate in an efficient range in the design of the lift, and the pump can operate safely and safely at the highest and lowest lift.
Main causes of low lift pump long-term operation is: this kind of pumping station built in the 1950s, when the design of pumping station pump type less, no suitable pump optional; or because of the lack of supply, and engineering and eager to start, can only choose other pump types; also according to high guarantee rate to determine the design head high, and even some at the maximum pump head selected, resulting in the actual head below the pump head design. For the recheck lift, power and speed matching unreasonable water pump should be adjusted or reformed.
2. reasonable regulation of water pump performance
If the performance parameters of the pump operation point do not meet the actual needs, the pump will run away from the high efficiency area for a long time. At this time, the way of changing the pump performance curve can be used to regulate the working point, so that the pump's work can meet the actual needs. The regulation method of speed regulating and variable diameter can generally be adopted for centrifugal pump. The adjustment method of speed regulating and changing angle is generally adopted for the adjustable blade pump.
3. strengthen the maintenance of the pump
After the pump is running for a long time, it will inevitably produce wear and tear, increase the energy loss in the pump, and reduce the efficiency of the fixed pump. Therefore, the monitoring work should be strengthened, the maintenance is carried out in time, the damaged parts are replaced, and the long and efficient operation of the pump is ensured.
4. guarantee the quality of the pump installation
The good working performance of the pump has a great relationship with the installation quality of the pump. If the quality of the installation does not meet the requirements, it will not only reduce the efficiency of the pump, but also generate vibration and noise when it is serious. It will cause the motor to overheat or even run. The vertical unit should ensure that the axis is located on the same vertical line. The axial and mixed flow pumps are adjustable with the blades, and the installation angles of each blade should be equal. For the pump, the shaft of the pump should coincide with the axis of the impeller. If it deviates from the running of the pump, it will affect the efficiency of the pump.
