SMH120R54E6.7W30三螺杆泵。稀油站SMH系列点火油泵
三螺杆泵的安装位置距油面太高,特别是在泵转速降低时,因不能保证泵吸油腔有必要的真空度造成吸油不足而吸入空气。此时应调整泵与油面的相对高度,使其知足划定的要求。
The installation position of the three screw pump from the oil surface is too high, especially in the pump speed is reduced, because the vacuum pump suction chamber can not guarantee the necessary degree of suction caused by insufficient inhalation of air. You should adjust the oil pump and the relative height, make it satisfy formularyrequirement.
吸油滤油器被污物堵塞或其容量过小,导致吸油阻力增加而吸入空气;另外,进、出油口的口径较大也有可能带入空气。此时,可清洗滤油器,或选取较大容量、且进出口径适当的滤油器。三螺杆泵不但能防止吸入空气,还能防止产生噪声。
Oil filter is blocked by dirt or its capacity is too small, resulting in increase in inhaled air oil resistance; in addition,inlet, outlet of large caliber may also into the air. At this time, can clean the oil filter, or select a larger capacity,and import oil strainer aperture appropriate. Three screw pump can not only prevent inhalation of air, but also prevent the generation of noise.
油箱内油量不够,或吸油管口未插至油面以下,泵便会吸入空气,此时应往油箱内增补油液至油标线;若回油管口露出油面,有时也会因系统内瞬间负压而使空气反灌进入系统,所以回油管口一般也应插至油面以下。
The amount of oil in the tank is not enough, or the suction nozzle is not inserted into the oil, pump will be inhaled air, at this time should go to the tank added oil to oil line; if the oil return pipe exposed out of the oil surface,sometimes as a result of system pressure and make the air moment in anti poured into the system, so the oil return pipe generally should be inserted the following to the oil surface.
三螺杆泵的泵体与两侧端盖为直接接触的硬密封,若接触面的平面度达不到划定要求,则泵在工作时轻易吸入空气;同样,泵的端盖与压盖之间也为直接接触,空气也轻易侵入;若压盖为塑料制品,因为其损坏或因温度变化而变形,也会使密封不严而进入空气。排除这种故障的方法是:当泵体或泵盖的平面度达不到划定的要求时,可以在平板上用金钢砂按字形路线往返研磨,也可以在平面磨床上磨削,使其平面度不超过5μm,并需要保证其平面与孔的垂直度要求;对于泵盖与压盖处的泄漏,可采用涂敷环氧树脂等胶粘剂进行密封。
Hard sealing end of the pump body and cover both sides of the three screw pump for direct contact, if the contactplane is not up to the designated requirements, are easily inhaled air pump at work; similarly, the pump cover andthe cover for the direct contact between, the air also easily invade; if the gland is a plastic products, because thedamage or deformation due to temperature changes, also can make the sealing lax and into the air. Method toeliminate this failure is: when the plane of the pump or pump cover degree is not up to the requirementsdelineated, can at the plate with steel sand in the zigzag route round grinding, can also be grinding on a surfacegrinder, the flatness is less than 5 m, and the need to ensure the verticality of the plane with holes the pumpcover and leakage; the cover, can be coated with epoxy resin adhesive seal
The framework oil seal pump shaft seal. Spring Rocca tight lip off, or anti oil package, or lips were strained, aging,will make oil seal is often in the state of negative pressure air inhaled, can be replaced with new oil seal to solve
泵轴一般采用骨架式油封进行密封。若卡紧唇部的弹簧脱落,或将油封装反,或其唇部被拉伤、老化,都将使油封后端常常处于负压状态而吸入空气,一般可更换新油封予以解决

新旋转窑*次点火必须采用SMH80和SMH120,SMH210点火油泵喷射雾化燃烧点火及挂窑皮期间的操作方法
1.窑头点火升温
1.1 窑头点火
现代化的预分解窑,窑头都采用三风道或四风道燃烧器,喷嘴中心都设有点火装置。新窑*次挂窑皮,使用轻柴油点火油泵SMH80R46E6.7W23和SMH120R42E6.7W23系列高压三螺杆泵,大型和超大型旋转窑一般采用SMH210R40E6.7W29点火油泵点火,其点火压力可以达到5Mpa。因为这样点火,柴油燃料在高压力下雾化效果好而且非常充分,燃烧就更加充分,保证了油煤混合燃烧,用煤量少,火焰温度高,煤粉燃尽率也高。如果用木材点火,火焰温度低,初期喷出的煤粉只有挥发分和部分固定碳燃烧。煤粉中大部分固定碳未燃尽就在窑内沉降。而且木材燃烧后留下大量木灰,这些煤灰和木灰在高温作用下被烧融,粘挂在耐火砖表面,不利于粘挂*、坚固、结实和稳定的窑皮。窑头点火一般用浸油的棉纱包绑在点火棒上,点燃后置于喷嘴前下方,随后即刻喷油。待窑内温度稍高一些后开始喷人少量煤粉。在火焰稳定、棉纱包也快烧尽时,抽出点火棒。以后随着用煤量的增加,火焰稳定程度的提高,逐渐减少轻柴油的喷人量,直至全部取消。在此期间,窑尾温度应遵循升温曲线要求缓慢上升。在RSP型分解炉上,为使RSP分解炉涡流分解室有足够的温度加速煤粉的燃烧,窑头点火前应将2个C4旋风筒排灰阀杆吊起。这样,窑尾部分高温废气可以进入涡流分解室经排灰阀、下料管人C4旋风筒,对涡流分解室起到预热升温的作用。
1.2 升温曲线和转窑制度
系统从冷态窑点火升温到开始挂窑皮期间窑尾废气温度、C5出口温度和C1出口温度以及不同温度段的转窑制度。当窑尾废气温度约为750—800℃时,启动生料喂料系统,向窑内喂入5%左右的设计喂料量,为挂好窑皮创造条件。
2.投料挂窑皮
当预热器系统充分预热,窑尾温度达950℃左右,这时分解炉涡流分解室温度可达650—700℃,窑头火砖开始发亮发白时,早先喂人的几吨生料也即将进入烧成带。这时,窑头留火待料,保持烧成带有足够高的温度,并将吊起的2个C4排灰阀复原。三次风管阀门开至10%左右,打开涡流燃烧室和分解室阀门,开始向涡流分解室喷轻柴油和少量煤粉。当C1出口温度达400—450℃时,打开置于C1出口至高温风机废气管道上的冷风阀,掺人冷风调节废气温度,保护高温风机。待C5出口温度达900℃时,适当开大三次风管阀门后即可下料。喂料量为设计能力的30%-40%。喂料后逐渐关闭冷风阀,适当加大喂煤量和系统排风量,窑以较低的转速(如0.3—0.6r/min)连续运转并开始挂窑皮。当系统比较正常,分解炉温度稳定后,就可以撤除点火喷油嘴。如果系统烧无烟煤,则应适当延长点火喷嘴的使用时间,但油量可以减少,以对无烟煤起助燃作用。
挂好窑皮是延长烧成带火砖寿命,提高回转窑运转率的重要环节。其关键是掌握火候,待生料到达烧成带时及时调整燃料量和窑速,确保稳定的烧成带温度。窑速与喂料量相适应,使粘挂的窑皮厚薄*、平整、均匀、坚固。挂窑皮期间严防烧成带温度骤变。温度太高,挂上的窑皮易被烧垮,生料易烧流,在窑内“推车”会严重磨蚀耐火砖;温度突然降低会跑生料,形成疏松夹心窑皮,极易塌落,影响窑皮质量。
挂窑皮时间,一般约需3—4个班。窑皮挂到一定程度以后,生料喂料量可以3-5t/h的速度增加,直至100%的设计能力。窑速和系统排风也随燃料和生料喂料量的增加而逐渐加大.
