内齿泵工作原理 NYP系列内齿泵(高粘度齿轮泵)具有内齿的驱动齿轮（外转子）带动内转子在全封闭的泵体内作同方向转动，泵体和前盖的月牙板使吸入口和排出口NYP series of inner gear pump (high viscosity gear pump) has a drive gear inside the tooth (outer rotor) drive the rotor within the pump body in the whole enclosed in the same direction as rotation, pump body and the front cover of the crescent plate so that suction and discharge outlet 隔开。separated. 转动时在吸入口形成负压，液体被吸入，转子将液体带到排出口，受压排出泵体，完成了液体的输送。Moved with the formation of negative pressure in the intake fluid is inhaled, the rotor into the liquid discharge outlet, pump discharge pressure to complete the delivery of liquid.
结构Frame
NYP系列内齿泵(高粘度泵)主要由内外转子、密封、泵体、轴、轴承、前盖等组成。NYP series of inner gear pump (high viscosity pumps) primarily by internal and external rotor, seal, pump, shaft, bearings, composed of the front cover. 密封方式有机械密封和填料密封两种，也可以根据用户的特殊要求而选用磁力驱动或零泄露结构；对于高温、高粘稠度及腐蚀性较强的介质，选用填料密封。Sealing methods are two kinds of mechanical seals and packing seal can also be based on the user's specific requirements drive the choice of magnetic or zero-leakage structure; for high-temperature, high viscosity and strong corrosive media, use packing seal.
NYP系列内齿泵(高粘度泵)输送易结晶物料时，在前盖和泵体上可设计带有保温夹套，工作时通蒸汽保温融化。泵可配安全阀，当泵或管路系统超压时，安全阀打开，形成内部回流，保证系统安全。
