一、操作前的准备工作：
（1）板框的数量是否符合规定,禁止在板框少于规定数量的情况下开机工作。 （2）板框的排列次序是否符合要求，安装是否平整，密封面接触是否良好。 （3）滤布有无破损，滤布孔比板框孔小且与板框孔相对同心。 （4）各管路是否畅通，有无漏点。
（5）液压系统工作是否正常，压力表是否灵敏好用。 二、操作中注意事项：
（1）安装压滤布必须平整，不许折叠，以防压紧时损坏板框及泄漏。 （2）液压站的工作压力橡塑板框最高工作压力不得超过20Mpa。
（3）过滤压力必须小于0.45Mpa，过滤物料温度必须小于80℃，以防引起渗漏和板框变形、撕裂等。
（4）操纵装置的溢流阀，须调节到能使活塞退回时所用的最小工作压力。
（5）板框在主梁上移动时，不得碰撞、摔打，施力应均衡，防止碰坏手把和损坏密封面。 （6）物料、压缩、洗液或热水的阀门必须按操作程序启用，不得同时启用。
（7）卸饼后清洗板框及滤布时，应保证孔道畅通，不允许残渣粘贴在密封面或进料通道内。 （8）液压系统停止操纵时，操作装置的长杆手轮应常开，短杆手轮应常闭，以保证安全，并避免来油浪费。 三、日常的维护保养：
（1）注意各部连接零件有无松动，应随时予紧固。
（2）压紧轴或压紧螺杆应保持良好的润滑，禁止有异物。 （3）压力表应定期校验，保证灵敏好用。
（4）拆下的板框，存放时应码放平整，防止挠曲变形。
（5）每班检查液压系统工作压力和油箱内油量是否在规定范围内。
（6）油箱内应加入清洁的46#液压油，并经80-100目滤网过滤后加入，禁止将含杂质或含水分的油加入油箱。
（7）操作人员应坚持随时打扫设备卫生，保持压滤机干净整洁，使设备本体及周围无滤饼、杂物等。 四、安全操作规程
1、所有规格压滤机上面所放滤板数量均不能少于铭牌规定的数量，压紧压力、进料压力、压榨压力与进料温度均不能超过说明书规定范围。滤布损坏应及时更换，液压油（春夏季用68号抗磨液压油，秋冬季用46号抗磨液压油）。一般环境下半年更换一次液压油，灰尘大的环境下1-3个月更换一次及清洗一次油缸、油箱等所有液压元件。
2、机械式压滤机传动部位丝杆、丝母、轴承、轴室及液压型机械型滑轮轴等每班应加注2-3次液态润滑油，严禁在丝杆上抹干式钙基脂润滑油，严禁在压紧状态下再次启动压紧动作，严禁随意调整电流继电器参数。
3、液压式压滤机在工作时油缸后禁止人员停留或经过，压紧或退回时必须有人看守作业，各液压件不得随意调整，以防压力失控造成设备损坏或危及人身安全。
4、滤板密封面必须清洁无褶皱，滤板应与主梁拉垂直且整齐，不得一边偏前一边偏后，否则不得启动压紧动作。拉板卸渣过程中严禁将头和肢体伸入滤板间。油缸内空气必须排净。 5、所有滤板进料口必须清除干净，以免堵塞使用损坏滤板。滤布应及时清洗。
6、电控箱要保持干燥，各种电器禁止用水冲洗。压滤机必须有接地线，以防短路、漏电。 7、隔膜式压滤机在过滤时排水及排气阀门必须在开启状态，压榨时应缓慢打开进水或进气阀，隔膜板腔内压榨水或是空气未排净以前严禁松开滤板。
8、必须经过一次低压（10Mpa）压紧，二次高压（20Mpa）压紧后才能正常进料，以保证滤板的平行度。
Filter press operation procedures 1 A, the preparation before operation:
1) The number of plate and frame is in accordance with the provisions,
banned under the condition of the plate and frame is less than the prescribed quantity work boot.
2) The order is in line with the requirements of plate and frame, installation
whether level off, the sealing surface contacts are in good condition.
3) whether the damaged cloth, cloth bore hole smaller than the frame and the
frame relative concentric hole.
4) Each pipe is smooth, there is no leakage points.
5) If hydraulic system is working properly, the gauge is sensitive handy. B the matters needing attention in operation：
1) Install pressure cloth must be flat, not allowed to fold, to prevent damage
to the frame and leak when pressed. Working Pressure
2) Plastic frame hydraulic station shall not exceed the maximum working
pressure 20Mpa.
3) filtration pressure must be less than 0.45Mpa, filter material temperature
must be less than 80 ℃, prevent deformation caused by leakage and frame, tear.
4) relief valve operating device shall be adjusted to the minimum working
pressure can be used when the piston return.
5) in the main frame beam moves will not hit, beaten, force should be
balanced to prevent damage to the sealing surface and damage the handle.
6) material, compression, lotion or hot water valve must be enabled by the
operating procedures shall not be enabled simultaneously.
7) the time frame and the cake discharge cleaning cloth, should ensure the
smooth flow channels are not allowed in the sealing surface residue paste or feed channel.
8) when the hydraulic system to stop manipulating, pole handwheel operation
of the device should be normally open, short lever handwheel should normally closed to ensure the safety, C Daily maintenance:
1) Pay attention to each connection parts with and without loose, shall, from
time to time to tighten.
2) compression axis or compression screw should be kept well lubricated,
prohibit a foreign body.
3) gauge should regularly check to ensure that sensitive and easy to use. 4) Remove the frame, storage should be stacked flat, to prevent deflection. 5) Check the hydraulic system working class and the fuel tank pressure is
within the specified range.
6) should be added to the tank clean 46 # hydraulic oil, and by adding the
80-100 mesh screen filter, prohibit or oil-containing water containing impurities added to the tank.
7) The operator should always insist on cleaning equipment sanitation, clean
and maintain the filter, so that the device around the body and no cake, and other debris.

D safety procedures
1 All specifications are put above the filter plate filter presses can not be less than the number specified number plate, pressing pressure, feed pressure, squeezing pressure and feed temperature can not exceed the range specified in the instructions. Damaged should be replaced filter cloth, hydraulic oil (No. 68 with the spring and summer wear hydraulic oil, autumn and winter with 46 hydraulic oils). The general environment in the second half to replace a hydraulic oil under dusty environments replaced every 1-3 months and clean all hydraulic components once cylinders, tanks and so on.
2, mechanical filter transmission parts screw, nut, bearings, shaft chamber and hydraulic mechanical type pulley shafts class 2-3 times a liquid lubricant should bear prohibited on the screw-type calcium-based dry grease lubricants, non-compressed state to start pressing in action again, free to adjust the current relay parameters strictly prohibited.
3, the hydraulic filter press cylinder after work or after a stay prohibiting staff, pressed or refund must be guarded job, all hydraulic parts are not free to adjust the pressure to prevent runaway equipment damage or threat to personal safety.
4, plate sealing surfaces must be clean and free of wrinkles, Plates should be straight and neat pull the main beam, while the former may not be biased while the bias, you may not start pressing the action. Drawing board prohibited dumping slag process between the head and limbs stretching Plates. Air inside the fuel tank must be drained.
5, all the inlet filter plates must be cleaned to prevent blockage of the filter plate using damaged. Cloth should be cleaned.
6, the electrical control box to keep dry, appliances ban rinse water. Filter must have a ground wire to prevent short circuits, leakage.
7, when the filtration membrane filter press drainage and exhaust valves must be in the open state, squeezing the water should slowly open the inlet valve or diaphragm plate cavity squeezing water or air is not drained before the non-release Plates .
8, must go through a low-pressure (10Mpa) compression, secondary hypertension (20Mpa) pressed to normal after feeding to ensure parallelism of the filter plate.
