NYP series stainless steel inner ring high viscosity pump precautions
March 08, 2024
NYP series stainless steel inner ring type high viscosity pump is a new type of positive displacement pump developed according to the needs of petroleum, chemical, paint, grease, medicine, dye, food and other industries. Because of its different materials and unique structure , So widely used in different nature, different viscosity of the medium transport. Before starting the operation, fill the housing of the gear pump with liquid to be transported for safe start-up. Gear pump rotation direction with the inlet and outlet ports. If the first gear pump operation, or long-term idle after use, it is best to run at no-load or light load first about an hour. If abnormal temperature rise, leakage, vibration and noise are detected in advance during running-in, the machine should be shut down for inspection. When transporting liquids with high viscosity or when the system is operating in a cold environment, it must be ensured that the transport medium will flow smoothly. Many oils contain wax components, which are easy to crystallize at low temperatures, so the best choice with insulation NYP series stainless steel inner ring high viscosity pump. In addition, the medium to be transported must be compatible with the rubber, such as seals, gaskets and hoses in the system. If the two are incompatible, the media must be re-defined. The selection of working pressure The rated pressure of the pump refers to the maximum working pressure of the pump when it is continuously working, and its working pressure is determined by the external load. The life of the pump is directly related to its working pressure. For infrequent work gear pump, the working pressure can be taken as the rated pressure of the pump, taking into account the different product quality, it is best to reduce the rated pressure of 20% to 30%. For the gear pump that often works under higher pressure, the working pressure should be 1 ~ 2 pressure levels lower than the rated pressure of the pump. Petrochemical equipment is often 24 hours continuous operation, when the working pressure of the pump should be much lower than the rated pressure, and the working speed should be lower than the rated speed. If the NYP Series stainless steel inner ring high viscosity pump operating pressure is adjusted too high, it will make the gear pump in overload operation.
