Failures and Repair Measures of Pressure Screen
Pressure screens are a new type of recycled pulp screening equipment, which can be widely used in the coarse screening, fine screening and screening of pulp before paper machines for various waste paper pulps. Pressure screens are pulping equipment and belong to the category of equipment accessories. During the application of pressure screens, scaling occurs due to factors such as process water, calcium and magnesium hardness, pH value, conductivity, total alkalinity, temperature, etc., which can easily lead to failures. Therefore, repair measures need to be taken. Let us introduce them t
The difference between brush filter and suction filter
Brush filter and suction filter are somewhat similar. They are two types of self-cleaning filters commonly used nowadays. Users are easily confused when purchasing. Next, let me introduce the difference between the two.
Introduction to brush filter:
During the filtration process of brush filter, impurities in the inner layer of fine filter gradually accumulate, and a pressure difference is formed on its inner and outer sides. When this pressure difference reaches the preset value, the filter will start the automatic cleaning process: the drain valve open
What are the reasons of blocking of cartridge dust collector?
The volume of the finished filter cartridge is closely related to the volume of the filter assembly. The main machine using the filter assembly often puts forward the following requirements for the filter:
①Total height and inlet and outlet distance (width) of the dust collector;
②Total height and diameter of the lower body of the filter cartridge;
③Total mass of the filter cartridge;
④Connection method and size of the air outlet;
⑤A series of performance requi
Fully Automatic Self-Cleaning Filter Cleaning Process
When the pressure difference between the inlet and outlet of the filter reaches the preset value (﹙0.5bar﹚) or the time setting value, the filter will start the self-cleaning process. The whole self-cleaning process includes two steps: opening the diaphragm drain valve located on the upper end cover of the filter; the motor drives the stainless steel brush in the filter to rotate, so that the impurities trapped by the filter are brushed off by the steel brush and discharged from the drain valve. The whole cleaning process takes about 15-30 seconds. During cleaning, the system keeps fl
What oil products can be processed by the oil filter machine?
The oil filter machine is a general name. In the process of filtering and purification, the oil filter machine plays the role of filtering, dehydration, degassing, regeneration, etc. The filtered oil meets the equipment use standards and improves the smoothness of the oil. When using the oil filter machine, you should also understand the usage of the oil filter machine. During the use of the oil filter machine, the filter element and filter paper of the oil filter machine will fail because the oil is too dirty. Therefore, the filter element and filter paper must be replaced every once in
What is the Differences between shallow sand filter and fiber ball filter?
Shallow sand filter:
Shallow sand filter is referred to as sand filter, which is a filter with quartz sand as filler. Quaternary sand filter is generally used as pure water pretreatment equipment and ultrafiltration equipment. Its main function is to intercept and adsorb sludge, colloid, metal ions and organic matter through the filter layer. Ordinary filter is made of stainless steel 304 material and is generally used for water treatment. It is widely used because of its pollution-free, low price and low operating cost.
Fiber ball filter:
Related Introduction of Filter Bags for Bag Filter
The interception accuracy of filter bags determines the interception capacity and pollutant carrying capacity of filter bags. The higher the accuracy, the better the interception capacity of filter bags under unit flow, the higher the fluid impurities captured, and the more pollutants intercepted by filter bags per unit time. The higher the quantity and quality of intercepted dirt, the higher the degree of pollution of filter bags, and the smaller the available effective filtration area.

Precautions for Automatic Back Wash Filters
1. The selection of automatic back wash filter specifications should match the installation pipeline. When the filter flow cannot meet the pipeline requirements, two (or more) filters can be installed in parallel or bypassed.
2. The filter should be installed in the place where the system needs to be protected as much as possible. The low inlet pressure affects the use, so it should also be installed near the pressure source.
3. The filter should be installed in series in the pipeline system. In
Misunderstandings of Daily Use of Hydraulic Oil Filters
1. A hydraulic oil filter with a bypass valve can be left unwashed or replaced for a long time after the filter element is clogged
Many users think that the bypass valve of the filter and the safety valve of the system have the same function: after the filter element is clogged, the bypass valve opens, and the system oil flows through at full flow, which has no effect on the system. This is a wrong understanding. When the bypass valve of the filter is opened, the pollutants blocked by the filter element (the filtered pollute
Fully Automatic Candle Filter Related Faults And Solutions

How to maintain the high precision oil filter？
According to common sense, maintenance is an important aspect of increasing the working time of mechanical equipment,especially Oil Purification Products. Many companies use high precision oil filters to extend the service life of production equipment or transportation machinery. However, this does not mean that oil filters used to service other machines do not require maintenance. So, how should the high precision oil filter be maintained during using?
1.Clean the filter promptly
As we all know, the high precision oil filter is a cleaning device that handles lubricating oil a
How to clean the filter bag for bag filters?
Filters bags have the advantages of reasonable structure, good sealing, strong circulation capacity, and easy operation. In particular, the filter bag has a low probability of side leakage, ensuring filtration accuracy and allowing quick replacement of filter bags, reducing operating costs. Therefore, for bag filters, the filter bag is a very important device, and the replacement of the filter bag is very convenient, and there are many different types to choose from.
The filtration methods of filter bags are divided into: external filtration and internal fi
How to use the quartz sand filter correctly?
