A sand pump that has been running normally for more than 2000 hours needs to perform regular maintenance and inspection, update the oil in the oil compartment of the bearing box, and regularly inject butter. It is recommended that the temperature of the shaft chamber be automatically detected by a temperature control device. The alarm system above 60 degrees lights up to indicate that the high temperature has exceeded the standard. Do regular maintenance and maintenance in a timely manner.
The working life of the over-flow parts of the whole pump is different due to the selection of different materials. The average time difference of using ordinary ductile iron is relatively short, and the replacement parts are frequent. It is not suitable for long-term operation. Optional Ziquan high chromium wear-resistant material can be used to assemble the overcurrent accessories, which can greatly improve the internal working time difference and delayed life of several times. When the pump outlet pressure is insufficient, measure the pressure and replace the pump blades in time. The order of replacing the pump blades is as follows: 1. Unscrew the pump casing bolts and remove the pump; 2. Reverse the card pump impeller to the end of the shaft and rotate it; Remove the ring from the back of the head.
The above steps are simple, the installation is reversed in the same order as above, and the replacement can be completed. After the impeller clearance is adjusted, the compression test is normal so as not to leak power.
