Daily maintenance and maintenance
Check the oil level in the gear box when the screw pump stops. If necessary, remove the filling plug and fill it to the center of the oil mark.
Listen for abnormal noise and vibration.
Check the leakage of the pump when it is running.
Note: For mechanical seals, in most cases, no leakage can be observed from the leak hole due to vaporization, but sometimes a small and stable leakage is allowed.
Characteristics of twin screw pump:
1. No stirring, no pulsation, smooth and smooth transmission of various media, because the pump body structure guarantees that there are always pumping liquids in the working elements of the pump as sealing liquids, all pumps have strong self-priming ability and can be mixed with vapor and liquid.
2. The special design of the pump ensures that the pump has a high inhalation performance, i.e. a very small NPSHr value.
3. The use of independently lubricated external bearings allows the transmission of various non-lubricating media.
4. Using synchronous gear transmission, the rotating parts do not contact each other, even if the short time dry rotation is not dangerous (1-2 minutes).
5. Horizontal, vertical, with heating jacket and other structural types are complete, can transport all kinds of clean medium without solid particles of low or high viscosity, choose the right medium, and even transport many corrosive media.
Welded twin screw pump has the following characteristics:
1. Fully heated parts are not easily deformed due to uneven heating.
2. On the same pump body, the material of the contact part with medium and the heating sleeve part can be different. In this way, multiphase mixed media and corrosive media can be transported. It can greatly reduce costs.
3. It is especially suitable for high temperature systems and special working occasions, such as transportation of high viscosity media as asphalt, heavy oil, residue and sulfide.
