Electrical fault analysis and treatment of commercial concrete filter press

  For users using commercial concrete filter press, the common problem is that the filtrate appears from the gap between the filter plate and the filter plate (i
e
the filter chamber cannot be sealed), which affects the commercial concrete filter press
Machine filtration quality and efficiency
In this case, we can solve it for the following reasons
First, the filter cloth is placed incorrectly
There are many reasons why the filter chamber cannot be sealed
We need to start with a simple filter chamber to see if the filter cloth is wrinkled or if the edge of the filter cloth is defective
Because the structure of the filter chamber is located between the filter plate and the filter cloth and bears great pressure, the filter plate is usually not prone to problems, and the rest are filter cloth
A seal is formed between the rigid filter plates, which plays a key role in the filter cloth
However, wrinkles or defects on the filter cloth may lead to gaps between the filter plates, but the filter chamber will not form a seal
Secondly, the pressure is insufficient
The filter plate and filter cloth must bear great pressure to realize the closed filter chamber structure
When the pressure is insufficient, the pressure applied on the filter plate is less than that of the filtrate, which can be taken for granted

html The analysis and treatment of the electrical fault of the commercial concrete filter press is expected to help you solve the problem
The causes of the electrical fault include: loose wires, wrong wiring, insensitive or damaged components, loose bolts, damaged or loose parts, mismatched circuits or oil circuits, high voltage, incorrect adjustment of relays, and unadjusted adjustable parts, The treatment of electrical faults such as internal disconnection requires electrical personnel to be familiar with not only the electrical schematic diagram and the performance of electrical components, but also the hydraulic schematic diagram, the control and power transmission relationship of commercial concrete filter press
At the same time, it is necessary to understand the working state and working process of commercial concrete filter press
Judge the fault area according to the time of fault occurrence, working process and action time
For some faults that are easy to occur, first check to speed up troubleshooting, such as loose wires, improper adjustment or damage of pressure relay 1
Only the concrete sewage filter press can be subject to routine commissioning, and the whole machine shall be comprehensively inspected before each shift
The mechanical pressure transmission parts and reducer must be filled with lubricating oil
For hydraulic compression, check the oil storage capacity of the oil tank and the working pressure of the hydraulic station
The hydraulic oil is usually changed once a year
When replacing, the hydraulic system should be cleaned once
Lower than the working pressure of oil cylinder, but not lower than the allowable value of filter pressure
Too small will cause a large amount of leakage and damage to machine parts 2 When the number of filter plates is less than the specified number, it is forbidden to leave the factory to avoid damaging the machine parts
Check the layout of the filter plate before feeding
The filter cloth cannot be folded to prevent large leakage
After removing the filter cake, the filter plates must be arranged closely 3 After normal operation, press the filter plate
The filter pressure and filter temperature must be within the specified range
Excessive filter pressure can cause leakage
If the filter temperature is too high, the plastic filter plate is easy to deform and the suspension will be suspended during feeding
Make the concentration uniform
There should be no impurities
After removing the filter cake, clean the filter cloth and filter plate, and do not let the residue stick to the sealing surface or feed channel, otherwise it will affect the stability of feed and the tightness of filter plate, resulting in leakage of filter plates on both sides
Unbalanced pressure can cause deformation and damage to the filter plate
