NYP high viscosity pump before operation considerations

NYP High Viscosity Pump Precautions before Operation The NYP High Viscosity Pump is filled with liquid to be delivered to the gear pump housing before starting operation, allowing for safe start-up. If the ambient temperature is below the freezing point, preheat the pump with heat steam beforehand and then start the gear pump. The direction of rotation of high-viscosity pump with inlet and outlet port line. 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. NYP high viscosity pump structure: NYP high viscosity pump is mainly composed of inner and outer rotor, shaft, pump body, front cover, bracket, seal, bearings and so on. Sealing a mechanical seal and packing seal in two forms, for high temperature, high viscosity and corrosive media, the choice of packing seal. When conveying the easily-crystallized material, the jacket and the pump body can be designed with a heat-preservation jacket, which can be melted by steam during work. From the spindle outstretched to pump clockwise rotation. NYP Stainless Steel High Viscosity Pump The drive gear with internal teeth (outer rotor) drives the inner rotor to rotate in the same direction within the fully enclosed pump body. The crescent plate of the pump body and the front cover separate the suction inlet and the discharge outlet. Negative pressure is formed at the suction port during rotation, the liquid is sucked in, the liquid is taken to the discharge port by the rotor, and the liquid is discharged under pressure to complete the liquid delivery. Due to the high viscosity of the medium fed by the high viscosity pump, the medium must be heated or insulated in order to reduce the flow resistance and increase the suction capacity of the pump. Heating elements are usually used to make viscous liquid heat evenly. If the temperature fluctuations, the delivery of high-viscosity liquid prone to degradation, it is recommended to use fluid heating, especially large displacement gear pump. Fluid heating is divided into built-in, external structure. The so-called built-in gear pump pump body or cover the internal design of the sudden heat jacket, the external is through the screw clamp jacket and pump body together. Into the jacket into the steam, HTF, or cooling water, according to the specific circumstances of the media. Built-in for the delivery of liquid temperature uniformity is higher, or require uniform cooling of high temperature liquid occasions. NYP high-viscosity pump conveying easy-crystallizing material, the front cover and the pump body can be designed with a thermal jacket, steam insulation melting work. Pump can be equipped with safety valve, when the pump or piping system overpressure, the safety valve opens, the formation of internal reflux, to ensure system safety.
