The double-cylinder filter press device of the diaphragm filter press is mainly composed of a pressure plate, a cylinder block, a cylinder base and a compression cylinder. The cylinders of the 2 compression cylinders are fixed on the cylinder and fixed with bolts. The piston rods of the 2 compression cylinders can move the pressure at the same time The plate moves on the rails of the left and right beams to complete the pressure. Tighten and loosen the filter plate. The positions of the 2 compression cylinders are up and down, left and right. However, in the process of pressing the diaphragm filter press, due to factors such as material gravity , the filter plate is easily affected by uneven stress, so the two compression cylinders of the current double-cylinder compression device are usually arranged up and down.

Diaphragm filter presses require regular maintenance during use, especially overhaul after commissioning. More attention is needed, and overhaul inspection is more important. Let's take a look at the "physical examination" notice issued by the staff.

1. Check the hydraulic station, including the content of hydraulic oil and the hydraulic coefficient of the hydraulic station. This is because the hydraulic station is an important power component of the diaphragm filter press. Whether it works normally depends on the pressure of the filter chamber of the diaphragm filter press. In the filter chamber It is more important to maintain a constant pressure.

2. Whether the sludge pumps of all sludges are mainly leaking and the seals of the bearings and seals of these sludge pumps. It usually takes half a month to check.

3. The oil observation window and speed control motor of the air compressor need to be checked. Lubricating oil has been added to the new equipment at the time of purchase, and the inspection is usually carried out within a month.

4. Check the control of these gases by checking the valve actuation of the exhaust valve and checking the pressure reducing valve.

5. Check the filter plate. At the beginning of the filter plate of the cavity diaphragm filter press, you can see the quality of the filter plate and check the oxidation of the filter plate. When the filter plate is eroded by water for a long time, the filter plate is in a water-containing state , the erosion depth of water is .

6. For the filter cloth of the one-month membrane diaphragm filter press, we should also check it, mainly to check its filtration conditions, whether it is damaged and whether the filtration flow is normal.

7. Check the motor and circuit of the diaphragm filter press. Check for excessive current and burnt wires; if there are any wires in the moving parts, the frayed area can prevent damage to animals such as mice.

The above are the large-scale maintenance work that needs to be paid attention to. I hope everyone can master it and apply it to daily operation to achieve the effect of prolonging the service life.
