Main Disadvantages
1. Problems that may arise from improper selection
When selecting ZJ series slurry pumps, if the coefficients of flow rate and head are not selected properly, it may result in pump specifications being larger than the actual working conditions. In this case, the pump may experience cavitation during operation, resulting in the combined effect of cavitation and abrasion on the flow components, leading to premature damage. Severe cavitation not only causes pump vibration and noise, but may also lead to a sharp decrease in pump flow, head, and efficiency, making it impossible for the pump to operate normally. In addition, excessive flow operation may also cause motor overload, heating, and in severe cases, may burn out the motor.
2. Limitations of transmission methods
The ZJ series slurry pump has various transmission modes, including direct connection, belt, hydraulic, variable frequency speed regulation, etc. However, different transmission methods have their own advantages and disadvantages. For example, although belt transmission can easily change the working parameters of the pump, its transmission efficiency is low, the belt is easily damaged, the operating cost is high, and the reliability is poor. It is not suitable for transmitting power greater than 220kW.
Improvement measures
1. Reasonable selection
In order to avoid problems caused by improper selection, users should make reasonable selections based on actual needs when choosing ZJ series slurry pumps. If you find that the selection is too large, you can consider using a low-speed high head or replacing it with a large-diameter slurry pump. This can avoid cavitation problems caused by excessive flow and head, and extend the service life of the pump.
2. Optimize the transmission mode
Due to the limitations of transmission methods, users can choose a more suitable transmission method. For example, if high transmission efficiency and reliability are required, direct drive can be chosen. If flexible adjustment of pump operating parameters is required, frequency conversion speed regulation or belt drive can be considered. For high-power situations where the pump speed is different from the motor speed, transmission methods such as gearboxes or hydraulic couplings can be used.
3. Regular maintenance and inspection
In order to ensure the long-term stable operation of the ZJ series slurry pump, users should regularly maintain and inspect the pump. This includes checking whether the installation of the pump unit is accurate and reliable, and whether there is any obvious vibration; Check if the bearing temperature is normal and if there is water seepage at the pump shaft seal; And regularly replace lubricating oil, etc. These measures can promptly detect and eliminate faults, reducing unplanned downtime of equipment.
Through the above improvement measures, the possible problems that may occur during the use of ZJ series slurry pumps can be effectively reduced, and their operating efficiency and service life can be improved.
