The invention discloses a front pump cover separating pulp pump, which comprises a pump body, a front pump cover, a rear pump cover, a pump shaft and an impeller. An impeller is installed at the output end of the pump shaft and extends through the back pump cover into the slurry channel of the pump body. The part of the pump shaft extending out of the pump body is supported by a bearing in the suspension, and the suspension is connected with the back pump cover through a connecting frame. The front pump cover is connected with the pump body through bolts and slurry inlet is formed on the front pump cover. The pump body is provided with a wear-resistant plate at the junction of the front pump cover and the pump body. The pulp pump of the present invention adopts a separate design of the pump body and the front pump cover, which can easily replace the wear-resistant front pump cover without dismantling the pipeline and pump body, greatly reduces the maintenance time and maintenance cost, and improves the maintenance efficiency; the inner diameter of the front pump cover from the slurry inlet to the direction of the pump body is asymptotically reduced, so that the slurry can pass through the feed. In addition, the front pump cover and wear-resistant plate can be replaced according to the actual production demand.
【技术实现步骤摘要】
一种前泵盖分离式纸浆泵
本专利技术涉及一种纸浆泵,具体涉及一种前泵盖分离式纸浆泵;属于造纸设备
技术介绍
造纸生产分为制浆和造纸两个基本过程,其中制浆就是用机械方法、化学方法或者两者相结合的方法把植物纤维原料离解变成本色纸浆或漂白纸浆,在生产过程中,通过纸浆泵将浆料进行输运,因而,纸浆泵是造纸领域的一类通用设备。现有纸浆泵泵体进料口在长期的负压工况下,浆料冲刷频繁,泵口处极易发生磨损,导致设备性能下降,因而需要定期检查和更换泵体,操作复杂且成本很高,影响生产进程。鉴于此,有必要对纸浆泵的结构进行改进。
技术实现思路
为解决现有技术的不足,本专利技术的目的在于提供一种维修方便、节约成本的前泵盖分离式纸浆泵。为了实现上述目标,本专利技术采用如下的技术方案:一种前泵盖分离式纸浆泵,包括:泵体、、前泵盖、后泵盖、泵轴及叶轮,所述前泵盖和后泵盖分设于泵体的两端,所述泵轴的输出端安装有叶轮且穿过后泵盖伸入泵体的浆料通道内,所述泵轴伸出泵体的部分由轴承支承在悬架内,所述悬架通过一联接架与后泵盖相连接,所述前泵盖通过螺栓与泵体相连且前泵盖上形成有浆料进口,所述泵体在前泵盖与泵体的相接处安装一耐磨板。优选地,前述叶轮为半开式叶轮,且叶轮的叶片数量为三片或四片,这样能够增加过流通道,可顺利输送高达6%浓度的精细浆料,并适用于含一定量的气体介质。更优选地,前述前泵盖为回转体结构,这样的结构更加有利于浆料的平稳输送。再优选地,前述前泵盖自浆料进口向泵体方向的内径渐近缩径,使浆料在进料过程中得到平缓的提速。更优选地,在前泵盖侧面还设有一辅助口,辅助口上设有盖体,维保时打开辅助 ...
