●高粘度泵概述High viscosity pump overview NYP型内环式高粘度泵是一种容积式内转子泵。这种类型的泵自吸性能强,适用于输送不含固体颗粒和纤维的粘稠液体,甚至是半固体状态的液体,最高输送粘度达到3*105厘泊。具有体积小、重量轻、脉动小、噪音低、运转平稳、寿命长等优点。NYP high viscosity of the inner ring type pump is a kind of positive displacement rotor pump.This type of pump self-priming performance is strong, is suitable for conveying viscous liquid containing no solid particles and fibers, even half solid state of liquid, conveying viscosity up to 3 * 105 centipoise.With small volume, light weight, small ripple, low noise, smooth operation, long service life, etc. 该型泵可广泛用于石油、化工、颜料、化工、颜料、食品、肥皂、洗涤剂及制药等行业。This type of pump can be widely used in petroleum, chemical, pigment, chemical, pigment, food, soap, detergent and pharmaceutical industries. ●高粘度泵使用时注意事项Matters needing attention when using high viscosity pump 进、出口管路的管径必须和泵保持一致;The diameters of inlet and outlet piping must be consistent with pump; 设计管路时应尽量减少弯头,且弯头角度不宜过小,进口管线不宜过长,以免影响自吸。 启动前每个注油杯都应家润滑油,且保证每天加油一次。 泵在工作前应该点动启动电机,观察转向是否和规定转向一致。 开机后观察运转是否正常,如有不正常噪音、特殊振动或温升过高等情况,应停机检查。 注意皮带松紧是否恰当,每半年调整一次。 ●高粘度泵工作原理: 高粘度泵是容积式内啮合齿轮泵,主动齿轮(外转子)带动被动齿轮(内转子)旋转时,不断产生封闭的空间,在吸油区齿轮逐渐脱离啮合而液体不断地充满齿间并被带到出油区,齿轮在出油区进入啮合时液体被排出。两个旋转齿轮的共同作用,形成一个稳定的体积排量,没有脉动。由于泵是完全对称的,泵可以反转,液流方向也随之改变。但应注意,泵的转向可能受到密封或泵内其它结构的限制,用户有反转要求时应在订货时做出说明。 泵在起动过程中应特别注意以下几个问题: 起动前要检查下列内容: 检查泵、齿轮箱和电机的对中程度; 检查过滤器中有没有焊皮和金属渣; 检查各连接部位连接是否紧固; 检查管路压在泵上的力和力矩是否超过给定的数值,如果温度较高,还应检查管路是否有膨胀节; 检查电气连接的正确性及电机的额定值,并检查电机转动方向是否正确; 检查泵的转动方向是否正确; 如有安全阀,安全阀安装必须正确, 检查泵轴是否转动灵活; 泵的内部不能是干的,特别是需要自吸的时候,应向泵内灌注一些油或输送的液体; 泵组装时在零件的表面有防护液,如果这种液体不能和泵送液体相容,则必须清洗; 最好在管路上安装压力表和真空表,方便观察泵的工作状态; 检查机械密封箱是否注满液体; 检查管路的阀门是否打开; 如果用内燃机驱动,请在起动发动机前保持离合器脱开; 泵起动后,检查液体是否进入到泵中,泵是否工作正常,如果长时间无液体进入泵中,应停机检查泵及管路。 ●高粘度齿轮泵并不能产生压力,它只是输出流量。压力低或无压力,说明高粘度齿 轮泵没有吸入液体或泄漏严重。High viscosity gear pump does not generate pressure, it is only the output flow.Pressure is low or no pressure, high viscosity gear wheel pump don't inhale the liquid or leakage is serious. 电动机输出功率偏小、齿 轮泵排量选得过大或压力调得过高时,也会造成压力不足 当然,压力表损坏或压力表节流孔堵塞时也显示不出压力,此时可换装一个新的压力表检查。Small motor output power, gear wheel pump capacity to choose too large or pressure too high, can cause stress Pressure gauge damage or pressure gauge orifice jams, of course, also could not show pressure, can change a new pressure gauge to check at this time. 如果确认泵无流量输出,可能是由于泵安装有误、泵的转向不对,或吸人侧(进液口及吸液管道)堵塞、出口止回阀装反或卡死了,也有可能是驱动轴断裂了。If confirmed that no flow pump output, could be turned to the pumps due to pump installation is wrong, wrong, or suction side (liquid into the mouth and suck liquid pipeline jam, export check valve installed backwards, or card is dead, it is possible that the drive shaft fracture. 高粘度泵在转速过低时会引起出液量不足,这种现象往往是由于泵的驱动装置打滑或功率不足所致。此时应检查齿 轮泵的实际转速、泵与电动机的联接及功率匹配情况等。High viscosity pump in low speed can cause insufficient quantity of produced liquid, this phenomenon is often due to the slippage of the pump drive or insufficient power.Check the gear wheel pump at this time of the actual speed, pump and motor connection and power matching, etc.
