Newly bought irrigation machine to re-tighten the screws in various parts before use. In the pump operation, should pay attention to bearing temperature, so that it does not exceed 75 ℃. And pay attention to the existence of noise, such as the occurrence of greater friction and percussion sound, should immediately stop inspection. When not in use, the pump should drain the water from the pump. After the pump is used for a period of time, the following fault will occur: The pump does not water the reason. Self-priming pump is not enough water storage, hand pump pressure pump body and inlet pipe water seal leakage. Suction too high, too low speed or triangular belt is too loose. The reason for the shortage of water. Filter or impeller clogged, speed is too low or too loose triangular belt. Impeller mouth serious water leakage. Bearing fever, noise and vibration larger reasons. The speed is too high, the pump shaft is bent. Incorrect bearing clearance, bearing wear or broken. In response to the above inspection, the timely adjustment or replacement. After adjusting, you can test run.
This series of calender is applied to all kinds of paper and paperboard's follow-up calendaring and finishing. When paper web passes through pressure area of each calender roll, it will be influenced by combined effect of pressure between rolls and surface friction, which plays a key role for improving smoothess, glossiness, tightness, stiffness and other physical indexes of paper and paperboard.
