速接头座；Ф19 通径-3m 胶管的两头分别与蓄能器上的接头座和油缸上通往有 杆腔的接头座连接；Ф19 通径-10m 胶管的一端与泵站上的另一接头座相连，胶 管另一端与油缸上通向无杆腔的接头座连接。各胶管插入接头座时，必须装入 U 形卡，以防出现高压油伤人事故。
1）可实现张紧力任意调节，完全可以实现启动张紧力为正常运行张紧力 1.3-1.5 倍的要求。
（2）响应快。带式输送机启动时，输送带在应力波的作用下处于振荡状态， 此时，张紧装置通过张紧油缸及蓄能站的快速响应保证输送带张紧力基本恒定， 从而使带式输送机启动时平稳、可靠，避免“打带”和过张紧现象，同时减少了 “飘带”和断带事故的发生。

SJ型水力加压器使用说明书D
水力加压器使用说明书一、概述水力加压器是一种应用于石油钻井、修井作业中的能量转换装置，它改变了钻井作业中靠下部钻铤的重量施加钻压的传统作业方式。
当在地质条件恶劣的地层钻进、大斜度井钻进、套管开窗侧钻或裸眼侧钻水平井或定向井钻进时，它在不消耗额外能量、不需要其它特殊设备的情况下，利用循环钻井液的钻头水眼节流压降，及其在活塞上下端面造成推力的差值给钻头加压。
解决了这些特殊钻井作业中不能靠下部钻铤的重量施加稳定钻压的技术难题。
它有效地改变了下部钻具的受力状态，起到了吸震防跳、实现自动送钻、改善钻头和钻具的工作条件，减轻司钻劳动强度、加快钻井速度、减少井下事故、保证井身质量的目的。
是石油钻井中一项投入小、效果明显、容易操作的实用技术和工具。
二、特点1、它改变了钻头加压方式：用泥浆压能为钻头提供稳定钻压，实现了柔性加压钻进。
改变了钻压调节方法，通过改变水力因素调节钻压大小，可节省部分钻铤、减轻钻机负荷。
有效的改善了钻压与钻速匹配关系，扩大了匹配范围，可在大钻压和高转速下钻进，提高了机械钻速。
减少了起下钻次数，提高了机械钻速。
2、它实现了减震效果“质”的飞跃：水力加压器利用开泵循环时钻头水眼节流压降，及其在活塞上下端面造成推力的差值，给钻头柔性加压。
从而最大限度的吸收了钻柱、钻头的冲击振动，克服了冲击振动产生的高峰荷载，解决了复杂地层钻井作业中吸震、防跳的技术难题、实现了标本兼治。
其减震效果是其它类型的减震器所不能比拟的。
3、水力加压器“人工送钻（加压器复位）—自动加压钻进—再人工送钻-再自动加压钻进，周而复始实现连续不断钻进的操作模式和入井使用时不需要特殊操作和特殊工具的优点。
使其操作十分简便可靠并减轻了操作人员的劳动强度，提高了井身质量。
4、提出了新的防斜、打直工艺理论。
原有的防斜、打直工艺，一般采用高速吊打的方法，这种方法虽然有效，但是在牺牲机械钻速的情况下实现的。
导向钻井系统虽然可靠，但比较复杂，耗费高。

允许最大给料粒度：10mm
给料压力：0.03～0.3 Mpa
处理能力（m3/h）与溢流口径和给料压力成正比，当给料压力为0.1Mpa，溢流口径为150mm时，处理能力为220m3/h。
3、本产品用聚氨酯弹性体材料制作（部分产品外镶铝壳），具有耐磨
性强，重量轻，不为酸、碱、盐溶液腐蚀，不易老化，不易锈蚀等优点。
但不应在高温条件下工作。
4、本产品适用于含固体泥浆（包括低粘度溶液）的颗粒分级、浓缩、
脱泥及水质净化作业，可用于选矿厂的闭路磨矿分级，尾砂输送或用于
井下填充、筑坝时的浓缩，非金属矿及化工原料的粉体制备，油田钻井泥浆的除碴净化，环保废水处理。
二、设备调整、使用
1、旋流器安装完毕，应当用水加压进行试验，在前表所列额定压力下，
确认无渗漏后，方可投料进行生产。
2、聚氨酯旋流器的使用温度不得大于80℃，最低不得小于－30℃。
3、旋流器给料中固体颗粒最大不得超过给矿口窄边宽度的1/10，如有
较多过粗颗粒应预先筛除。
4、旋流器的单台处理能力按下式近似计算：
Q=0.98 KD · dg · dy(10P)1/2 m3/h
dg----给料口当量直径，dg=｛4/π(1·b)｝1/2 cm；
dy----溢流口直径 cm；
P-----给料口压力 Mpa；
KD----旋流器直径修正系数；KD=0.8＋1.2/(1＋0.1D)；
5、单台旋流器的生产能力在小范围内可以通过改变溢流管直径或给
料压力予以调整，若与生产能力要求相差很大（如一倍以上），即应改换旋流器规格。
6、旋流器的溢流与沉砂粒度及数量比通过改变沉砂口直径与溢流管
直径的比值（称作角锥比）予以调整。
但这种调整对闭路磨矿分级旋流器效果不会明显，因为此时的分级产品粒度主要取决于磨矿机的磨矿效果。
三、操作与维护
1、水力旋流器在工作中应尽力保持给料压力和给料浓度稳定不变，这
样方能避免产品粒度波动并获得较高的分级效率。
2、旋流器的易磨损件主要是沉砂嘴。
当沉砂嘴直径增大时，沉砂产率
提高，溢流量减少。
应经常进行检查并适时更换。
3、水力旋流器机组一般勿须设专人就地看管，但须经常巡视给料是否
正常，设备有无磨损、漏浆事故，以及沉砂口是否发生堵塞等情况。
