NYP advantage rotor pumping medium NYP rotor pump can transport high viscosity, high concentration of solid particles in lubricating medium or small soft particles; high efficiency, stable performance, long service life. High viscosity pump can be used insulation jacket structure, high viscosity pump insulation when transporting relatively high viscosity material, thereby reducing the viscosity of the medium, to achieve better delivery results, but there is no single screw insulation jacket structure; high viscosity pump After a period of time, if the pump is worn inside the gap, based on their own without dismantling the pump can pump high viscosity material viscosity delivered to adjust the gap of the pump, and the same can be adjusted new pump to achieve good results. Hon Hai high viscosity pump can be equipped with a safety valve, when the pump or piping system overpressure safety valve opens, the formation of internal return, ensure system security. The single screw pump itself cannot be provided in the safety valve, can only be provided in the pipeline, to improve the equipment investment costs and installation costs. Must consider the medium viscosity, high viscosity pump conveyed when selecting high viscosity pump, which can be determined within NYP engages pump rotor speed range, according to the normal speed range of flow rates and high viscosity pump working conditions needed to pump high viscosity range in order to determine the specific type rotor pump NYP. Note that in general the media can be selected. Among them, some special chemical medium at a certain temperature changes its chemical composition, so it is necessary to select a high viscosity pump should pay special attention to the pump speed is appropriate, because the higher the speed of the pump, the heat generated in normal operation, the greater once over medium temperature limit, then much of the media transport caused damage. Also some food media, such as jam-like, like our daily consumption in the jam, peanut butter, bean paste, etc. These media requirements during transport must not be able to destroy its internal components destruction, which requires us to selected pump speed must be low in order to ensure NYP rotor pump in the transportation process does not destroy the transmission medium. NYP rotor pump during operation often appear stuck axle turn no phenomenon, mainly due to the high viscosity of the medium, high viscosity pump are often delivered, there are physically mixed some impurities. If the pump inlet filter is not installed right, then once a large number of hard particles into the pump chamber will put NYP rotor pump rotor stuck inside and outside, so that the pump will not turn, will NYP serious internal and external rotor pump destroyed.
Therefore, we recommend when installing Honghai pump rotor pump should select the appropriate filter to be installed at the inlet of the pump. High viscosity pump axle phenomenon is mainly reflected in the large stainless steel high electric gear oil pump, because of the low carbon content stainless steel, so the thermal expansion coefficient, once the pump temperature is too high, it will cause the interior fittings between the pump and accessories the gap narrowed to a certain extent it will have after locking phenomenon. So choose stainless steel high viscosity pump is sure to indicate the specific temperature, and lubricating medium. Low and high viscosity pump speed to medium viscosity has a close relationship. If the viscosity of the medium pumping high viscosity is too high, and the distribution of the speed is also too high, it will cause the pump flow rate is low, the pump noisy. If the motor power or by routine to match, then the motor will cause overload. The main pump speed is too high, too high viscosity of the medium so that the pump will cause great resistance, instant motor starting current exceeds the rated current, resulting in motor overload; the speed is too high, so high viscosity pump in operation inside the rotor almost just formed a spin around the transmission medium slip, causing the material does not absorb or flow is very small. In this situation, the pump speed must be reduced, increasing the motor power, to reduce the diameter to increase the import and export of the flow resistance of the medium. Thereby to complete the delivery of the working medium. After the speed is reduced, the pump flow will actually and the noise of the pump will be reduced, but it is certainly not hit the theoretical flow. So if you need to flow with the actual conditions differ too much, then it can only pump a little bigger and better models. Another problem prone NYP rotor pump driven gear pin is easy to wear, especially for transport when no lubrication medium, particularly fast wear pin. I am improving processing technology company based on the original des ign improvements to the pin through a special package plus a grease lubrication system. Centrifugal force of the negative pressure in the case of high viscosity of the normal operation of the pump generated by the rotation of the inner rotor, the use of fuel injection systems through a special channel to the pin oiling, so as to solve the high viscosity of the fast wear of the pump-shaft pump exist in the industry problems Honghai Pump Co., Ltd.
