2, because the rotor pump is a fixed capacity pump, displacement per revolution, once the process for some reason to stop working and the pump is still working, then the pump pressure will rise indefinitely, eventually leading to seal leaks, mechanical damage Such as accidents, for which we must take effective preventive measures. Example 1: With the upper and lower processes should be chain, when the next process downtime, stop the pump at the same time. Example 2, the output of the pipeline can be installed safety valve and overpressure circuit system, once over-pressure will be automatically unloaded.
3, if the rotor pump control valve, it can only be installed in the pump inlet pipe, outlet pipe should not be installed on the control valve, easily lead to over-pressure error.
After all the installation, should conduct a comprehensive inspection, including mechanical parts, electrical wiring, etc., and then hand pump the pump 3 to 5 turns to observe whether there is any stuck or loose phenomenon until normal, and then through the electricity Test run, if found abnormal, due to stop overhaul, paternity everything after the normal delivery.
Rotor pump operation:
Rotor pump operation is convenient and safe, just press the button, turn on the power, they began to work properly, to ensure that the pump can work better, but also pay attention to the following essentials.
1, before opening the rotor pump: first check whether the parts of the pump intact, out of the valve on the pipeline are all open, in short, must ensure that the parts intact, smooth piping.
2, in the open rotor pump: it must be the next process equipment to start work, and then, to start the pump.
3, the rotor pump in operation, should always pay attention to the action is normal, such as the discovery of the pump before the stop flow or blockage after the phenomenon should be promptly shut down, remove the fault and then boot.
4, when the entire line to stop working, according to the process in turn downtime, that is, after the pump stopped, then stop the pump behind the relevant equipment.
For any mechanical equipment, normal maintenance work done well, it is not only reflected in the production is normal, more important directly affect the use of machinery and equipment ordered, for the pump, of course, is no exception, to this end, pay attention to the following Maintenance work.
1, Seals, rotor pump seal is divided into static seal and movable seal, static seal sealing ring (should pay attention to the surface without scratches or bumps, otherwise, to directly affect the sealing effect; for the movable seal , Because it can be affected by the pressure and corrosion of the transport medium, as well as the abrasion of the particles in the medium, etc. (If there is a slight mistake, leakage may occur.) Once the product is leaked, it should be shut down for maintenance in time. Clean cotton wipe, coated with a layer of glycerin, after assembly, the first hand before use, such as repair hopeless, should be replaced with new pieces.
2, lubricating parts, the pump gear, rolling bearings, lubrication conditions must be maintained, usually, always pay attention to the level of gear in the oil, given adequate lubricants, and to ensure the pure, clean, regular oil (six Month or year) to replace the new oil.
3, the electrical system, in the vicinity of electrical equipment, are not allowed to store the destruction of insulation equipment, substances or gases. At the same time must keep the electric equipment in a dry environment. If it is difficult to avoid the installation of moisture-proof facilities
4, routine maintenance, whenever the downtime does not work, according to the nature of the delivery of materials, choose the appropriate cleaning agent, the pump for effective cleaning, and finally have to use water to clean it again to ensure that the pump clean.
