Application and features of NYP high viscosity pump

NYP high viscosity pump is especially suitable for conveying high viscosity and consistency media. Pump head, pump housing, sealed chamber part can be with insulation jacket. According to the actual needs of the need to select the location of insulation. Jacket and pump body cast into one, thermal insulation effect is good, to avoid welding jacket produced a variety of problems. To be heated: through the heat steam, HTF and other heat medium into the jacket chamber can be insulated. To be cooled: through a variety of cooling fluid, you can keep the pump temperature. NYP high viscosity pump important inner and outer rotor, shaft, pump body, front cover, bracket, seal, bearing and other synthesis. Sealing machine seals and packing seal two situations, given the high temperature, high viscosity and aggressive media, the optional packing seal. Easy to transport material delivery, the front cover and the pump body can be designed with a thermal jacket, working through steam insulation melt. From the spindle extension to the pump for the clockwise rotation. The transport medium is not only an intermediary for energy transmission, but also a lubrication, sealing and heat transfer medium. Gear pumps that deliver high-viscosity fluids should deliver the highest level of flow at lower power, less leakage, and greater pressure. Fluid viscosity reflects the ease of flow of the media, sticking too high will increase the resistance within the wipe, reducing output power, spread energy, and the system temperature is too high. When establishing the medium to be delivered, it is reasonable to follow the instructions in the product manual carefully and try to use the fluid medium supported by the manufacturer, and pay attention to the range of working temperature for weighing the system. When you want to use it over a wide range of temperatures, the viscosity index of the conveying medium should be reasonably high. When the viscosity of the conveying fluid is high, or when the system is operating in a cold environment, it must be ensured that the conveying medium can flow smoothly. Many, many oils contain waxes that are very, very, very crystalline at low temperatures and have a pour point below the minimum expected homework temperature. In addition, the medium to be transported must be compatible with the rubber materials in the system such as seals, bedding and hoses. If the two are incompatible, the transportation medium must be established from the beginning. High-viscosity pump bearing or flange and its drive motor should be quoted with the installation of basic, basic, flange or bearing must have sufficient rigidity to reduce gear pump operation occurred when the sensation and noise. The electric motor and gear pump shall be connected with flexible coupling, the concentricity is less than 0.1mm and the inclination angle is not greater than 1 degree. Do not hammer when installing the coupling, so as not to damage gear and other components of the gear pump. If the pulley, sprocket and other drive should be set brackets to prevent the positive gear shaft radial force. Tighten the gear pump, the idea of ​​the foot palm screw, the screw force should be average, reliable connection. When rolling the coupling by hand, you should feel the gear pump can easily roll, there is no clamping and other anomalies, and then piping. High-viscosity pump oil suction pipe diameter should be large enough and remove the narrow pipe or slipping away, reduce the elbow, remove unnecessary valves, appendix, as far as possible to reduce the pump installation height, shorten the suction pipe width to reduce the pressure loss . The fittings of the pipe joints should be well sealed to infiltrate the embankment with oxygen so as to control the cavitation and cavitation. Before running, fill the housing of the gear pump with fluid to be delivered for safe start-up. If the ambient air temperature is below the freezing point, preheat the pump with heat steam and preheat it before starting the gear pump. Gear pump rotation to the wind and into the oil port line. Gear pump if the first run, or perennial re-use, it is best to run at no-load or light load for about an hour before and after. Ruoyi phase in the run-ahead phase to detect abnormal temperature rise, leakage, sensation and noise, should stop checking. Check Valve and Safety Valve It is advisable to install a check valve on the output line of the gear pump. This way when picking up the pump and the output pipe, the fluid in the system does not flow backwards. Gear pump with load parking, but also reversal of dike pump in its output pipe partial vacuum. It should be noted that the outlet check valve can not be installed or stuck phenomenon. The high-viscosity pump outlet pipe should also be attached to safety valves and other protective installation, so that once the pump outlet pipe infarction, you can open the relief valve relief. The safety valve can be cast in one piece with the pump body or the pump head and can also be assembled in one piece. In view of the demand of high viscosity pump reversing, the import and export pipelines are required to attach a safety valve.
