stainless steel hydraulic filter, filter industry is professional term, in order to purify the original ecological resources and resource recycling, and need of purification equipment, now filter is mainly used in oil filter, air filter, water filter, air filter and other filter industry.

Remove fluid or a small amount of solid particles in the air, can the normal work of the protection device and the air is clean, when the fluid is placed into a certain size of filter cartridge, the impurity is blocked, and clean flow through the filter out.

In the middle of the water filter, filter belong to one of relatively stable water filter filtration efficiency, what determines its filtering stability?
Mainly from three aspects are analyzed.




a work, melt-blown filter pressure loss is small, filtration efficiency and stability.

Polypropylene melt-blown cartridge in fine chemical fiber layer and rough fiber forming double fiber structure, reasonable reduces the loss of pressure of work, maintain the relative stability of filtration efficiency.




2, melt-blown cartridge filter with high efficiency.




the melt-blown cartridge is different from the traditional fabric filter material, fiber diameter is relatively small, generally for 5 -
25 micron;




the irregular net-like porous structure of three-dimensional space, small aperture, the average pore diameter less than 40 microns, the porosity is large, the average porosity of 75% or higher, reasonably adjust the filtering accuracy and filtering the production of polypropylene melt-blown cartridge series of products the indicators through additional measurement.







3, long using time, filtering the cost is low.




melt-blown filter pore diameter gradient distribution along diameter direction (

According to the requirements of different medium filter can not only from inside to outside became smaller, can also be from outside to inside gradually become smaller)
。




in the process of filtering, big aperture section to accommodate large particles, there is enough space to ensure filter will not be fast blockage, and provide good shape stiffness:


small aperture section can jam tiny particles, guarantee the filtration precision, fast to avoid the high precision filter clogging and the shortcoming of short service life, reduced the filtration resistance, reduce the energy consumption and improve the service life of the filter.

Water purifiers have gradually become a household necessity, and their filter elements are the core of water purifiers. Therefore, the installation of water purifier filter elements is something that every family needs to face, and the water quality requirements of water purifiers not only depend on the quality of the filter elements, but also Depends on the service life of the filter element and whether it is replaced in time. Installation of water purifier filter element ① If the water pressure is higher than 3 kg, a pressure reducing valve should be installed at the water inlet. ②If the main water inlet pipe is far from the installation place, a ball valve should be installed in front of the product water inlet. ③ Unpack and check whether the joints of each filter housing are tightened. If there is looseness, tighten them in time to prevent water seepage. ④Put the hollow fiber membrane filter element (fourth stage) into the fourth stage filter element, remove the activated carbon filter element (second and third stage), rinse with clean water until no black water flows out, and then put it into the shell, ready for work. ⑤Select the installation location of the machine according to the customer's requirements. When drilling holes with an electric hammer, the drill bit should be increased from small to large, and the strength should be increased from small to large, so as not to damage the decoration of the customer's home. After the hole is drilled, put in the expansion gong bolt of the same size, and then hang up the machine and tighten it. ⑥When connecting the water source, first turn off the main water valve, then install the matching tee, connect the second branch of the water inlet pipe, and tighten the gong mother. ⑦According to the needs of the customer, select the installation position of the water tap, and install the water outlet connection pipe (two points). At this time, the sewage pipe and the water outlet pipe are completed synchronously. ⑧If you need to connect the water dispenser, you need to install a tee at the purified water outlet. ⑨ The pipeline connection of each product is carried out according to the product manual. Water quality requirements for water purifiers 1. The water purifiers must generally be tap water at room temperature and cannot enter hot water. Therefore, the water purifiers must be installed in front of hot-temperature devices such as water boilers, and the installation position of the water purifiers should be low. To prevent the steam in the water boiler from entering the water purifier and damaging the filter element of the water purifier. 2. All pipelines, joints, faucets and other wading accessories on the water purifier should meet the national hygiene standards. 3. Do not install it outdoors in the northern region to prevent the ultra-filter from freezing and cracking, and at the same time prevent direct sunlight. 4. Do not use too much force when tightening the threaded joint during installation to prevent the joint thread from slipping.

The filter element of the water purifier of the pure water machine has a certain service life, and the filter element of the water purifier of the pure water machine needs to be replaced in time after reaching the limit of use, so as to always ensure the healthy and clean water quality. How to replace the water purifier filter element of pure water machine What is the filter element? The replacement methods of the filter element of different water purifiers are different. Here are some common ways to replace the filter element of household water purifiers. Replacing the filter element of the front water purifier When replacing the filter element of the front water purifier, first close the water inlet three-way ball valve, unplug the two hoses at both ends of the front transparent bottle, and adjust the water control in the front transparent bottle. Dry, then unscrew the white quick connector at the water outlet of the pre-filter (with the OUT mark), unscrew the pre-transparent bottle to take out the old filter element, clean the inside of the filter bottle and the filter bottle cap, and put in a new one of the same specification. the filter element, screw on the black cover (to avoid shifting the O-ring rubber ring), then use the adjustable wrench to fasten the white quick connector, and finally insert the white hose into the water inlet (marked with IN) and the outlet of the pre-filter respectively. water outlet (marked with OUT), so that the replacement of the filter element of the pre-filter is completed. Replacing the filter element of the pure water machine (1) The replacement method of the front three-stage filter element of the pure water machine: When replacing the front three-stage filter element, first turn off the electroplating ball valve and the pressure bucket ball valve, and open the gooseneck faucet to clear the pipeline. When the water stops flowing out, open the filter housing with the filter element with the filter housing wrench, take out the old filter element, put in a new filter element of the same specification, and coat the black O-ring above the filter housing with Vaseline. Wait for the lubricant, then put the O-ring into the groove in the filter housing, tighten the filter housing in a vertical manner, try to avoid the displacement of the O-ring, and finally open the electroplating ball valve and the pressure bucket ball valve. (2) How to replace the RO reverse osmosis membrane of the pure water machine: When the RO reverse osmosis membrane of the pure water machine is better, first close the electroplating ball valve, wait for ten minutes, then unscrew the nut joint on the right side of the membrane shell, and pull out the water pipe , then close the ball valve of the pressure bucket, unscrew the nut joint above it, and guide the water pipe into an empty bucket or washing tank, hold the reverse osmosis membrane tube tightly with the left hand, and then clamp the old reverse osmosis membrane with pliers. Pull out the membrane casing by force. Insert the newly opened reverse osmosis membrane into the reverse osmosis membrane tube until one end of the two small black O-rings touches the bottom end of the membrane shell, and then screw the membrane shell cover tightly. Plug in the water pipe and tighten the fitting nut. Then open the electroplating ball valve, let the machine run for more than two hours, and make the system enter the normal water production state, then connect the water pipe to the pressure tank ball valve and open the pressure tank ball valve.
