高压均质机使用说明
高压均质机使用说明1.高压均质机工作原理高压均质机主要由柱塞泵、均质阀等部分组成，常用柱塞泵为三缸柱塞泵，由3个互不相连的工作室、3个柱塞、3个进料阀和3个出料阀等组成。
通过曲轴连杆机构和变速箱将电动机高速旋转运动变成低速往复直线运动。
由活塞带动柱塞，在泵体内做往复运动，完成吸料、加压过程，然后进入集流管。
进料管和排料管相通，在料液的排出口装有安全阀，当压力过高时，可使料液回流到进料口。
由于曲轴设计为使得连杆相位差为120°，这样可以使排出的流量基本平衡。
在料液的排出口安装有均质阀。
高压液料由集流管输送至均质阀，使得料液颗粒度降低、分布均匀。
均质阀有两级均质阀及两级调压装置，可完成超微粉碎、乳化等。
2.高压均质机使用维护（1）操作①开机准备首先检查电动机转动方向和传动箱内润滑油的油位。
开启冷却水，保证调压手柄处于旋松完全无压力状态（放松手柄1～2圈），打开进料阀和出料阀。
②起动主电动机，在无负荷的情况下运转几分钟，使设备各部件能充分润滑，同时可将泵体内空气排尽。
待出料口出料正常后，旋动调压手柄。
先缓慢调节二级调压手柄，再调节一级调压手柄，缓慢将压力调至使用压力。
③关机先缓慢放松一级调压手柄，再缓慢放松二级调压手柄卸压，当压力为零时再关主电动机，最后关冷却水。
(2)维护①定期检查油位，以保证润滑油量充足。
定期在机体连接轴处加些润滑油，以免缺油，损坏机器。
②启动设备前应检查各紧固件及管路等是否紧固。
启动前应先接通冷却水，保证柱塞往复运动时能充分冷却。
③严禁带载起动，工作中严禁断料，设备不得空转。
④调压时，须十分缓慢地加压和泄压。
⑤停机前须用净水洗去工作腔内残液。
⑥不能用高浓度、高黏度的料液来均质。
禁止粗硬杂质进入泵体。

操作规程:
(1)按逆时针方向稍微松开高压阀手轮(A)和低压阀手轮(B)。
(2)料斗内放入3-5公升自来水，把料斗下面的三通阔手柄挽到垂直位置，使液体进入高压泵内。
(3)按顺时针方向拧紧压力表底座(D)针形阀手柄，使压力表锁定。
(4)把出料口的三通阀(E)手柄拨到垂直位里上，使工作液循环工作。
(5)启动电动机(即接通电源)，这时泵内的柱塞已开始工作，将泵内空气排尽，看见液体后就可加压。
方法:首先顺时针方向徐徐绞紧低压阀(B)，直到压力表上压力指示在10MPa左右，然后再顺时针绞紧高压阀(A)，直到压力表上指示值约20MPa，若工作正常，则可正式启用。
(一般为:低压约为总压的一半)。
每当工作完毕，应先松开高压阀(A)手轮一圈后再松开低压阀(B)手轮一圈切勿搞错！(加压与减压相反).
(6)用完后必须用清水清洗干净(稍加压清洗)。
注意:1.料液中不能有结团粘块，可先用胶体磨处理，开机前向曲轴箱两侧的玻璃油杯内注满润清油。
2.压力表底座(D)针形阀锁定后，压力指针具有增加压力时才向压力方向移动，降低压力时指针不动，只有拧松压力表底座(D)针型阀后再拧紧才指示当前压力。

To avoid the particles of impurities (such as iron, glass, etc.) into the homogenizer to wear inlet valve and homogenizing valve, every materiel should be filtered by filter screen of 60-100 mu before it is put into homogenizer to homogenized.2. It is forbidden to operate machine long time when there is no material3. Do not turn on homogenizer under handle was tightly, for sudden overload capacity will damage motor.4. AH08-100 homogenizer is designed for production. The machine can work for a long time.5. Solid ceramic plunger used for homogenizer. So the temperature changes of product contact pieces couldn’t over 70℃, or the plunger may rupture. The range of temperature changes shouldn’t over 5℃, especially under cleaning operation.1 The theory of Homogenization1.1 What is homogenizationHomogenization is finished by homogenizing valve and piston which can refine the material occurred in the homogeneous valve and mix them.1.2 The theory of homogenizationMaterial is inhaled through the piston. With the help of the plunger, it can enter the gap. Also, the size of the gap is changing with different pressures. Releasing the pressure, the material eject with the speed of one thousand to one thousand and five hundred meters per second. Three effects produced after the material hit the impact ring which is one of the valve components .Hole effectThe material accumulated high energy after pressed by the plunger. When passing the limiting gap, it can release high energy after the sudden decreasing of pressure. Through it , the material can be smashed and refined .This is called Hole effect.Impact effectWhen passing the limiting gap, the material smashed and refined after hitting the special impact ring.Shear effectThe high speeding material produce strong shearing when crossing the valve chamber channel and limiting gap.1.3 Function diagram of plunger pump1.4 Function diagram of homogeneous valve1.5 Function diagram of two stages homogeneous valves2Introduction of equipment structure2.1Pressure block1- stainless inlet cup 6- inlet pipe2- inlet valve plunger 7- outlet pipe3- outlet valve plunger 8- pressure block4- pressure gauge 9- the first stage valve 5- the second stage valve2.2ceramic plunger1- solid ceramic plunger 2- locknut3- tension ring 4- spacer ring- plunger seal2.3inlet valve1.fixed nut2.fixed plug3.gasket4.o-ring5.spring6.ceramicball7.inlet valveseatPressure block was made of two-phase alloys stainless steel.

________________________________________________________________________________FB1均质原理1.1何为均质均质是由柱塞泵和均质阀共同作用使物料在均质阀区发生细化和均匀混合的过程。
1.2均质原理物料通过柱塞泵吸入并加压，在柱塞作用下进入压力大小可调节的阀组中，经过特定宽度的限流缝隙（工作区）后，瞬间失压的物料以极高的流速（1000 至1500 米/秒）喷出，碰撞在阀组件之一的碰撞环上，产生了三种效应：1、空穴效应被柱塞压缩的物料内积聚了极高的能量，通过限流缝隙时瞬间失压，造成高能释放引起空穴爆炸，致使物料强烈粉碎细化。
