Introduction: The small-sized screw pump has a large effective suction range, flexible installation, and bidirectional delivery.
The screw pump is a volumetric rotary pump. It absorbs and discharges liquid by changing the volume of a sealed chamber formed by a screw and a bush. As a sewage treatment equipment, it is widely used in conveying water, wet sludge and the like.
The small-sized screw pump is a new pump type small-sized screw pump that works according to the principle of twisting and meshing displacement, and has the characteristics of large effective suction range, flexible installation, and two-way transportation. In addition, the small-sized screw pump runs smoothly, smoothly, with low noise, no pulsation, and no shear when conveying high-viscosity media.
What problems will the screw pump encounter during use?
Poor pumping is a common problem with screw pumps. There are several causes and solutions:
one. The screw pump vibrates violently. The cause of this problem may be the imbalance of the electric rotor, or problems with other internal parts. Need to adjust, repair, reinforce or replace internal parts.
two. Screw pump packing is overheated. This is mainly due to the over-tightening of the packing pressure so that cold water cannot enter the packing. It is also possible that the shaft surface is damaged. Can properly relax the packing, clear the plug seal. It should be noted that if the packing wears out, it must be replaced.
three. The screw pump line leaks or leaks. This may be due to the nuts being not tightened during installation. If the leak is serious, it must be disassembled and reinstalled. When it is not serious, you can apply grout to the leak. If the joint leaks, simply tighten the nut by hand.
four. Screw pump does not absorb or drain. Most of the reasons are that the bottom valve is stuck, the filter water is partially blocked, the water absorption height is too high or the water absorption leaks. Other reasons may be misdirection and blockage of the impeller passage. This situation requires the inspection of the screw pump, taking measures according to the specific situation.
The function of Car Air Purifier:
Car air purifier refers to vehicle air purifier. It refers to air purification equipment specially used to purify PM2.5, toxic and harmful gases (formaldehyde, benzene series, TVOC, etc.), peculiar smell, bacteria and viruses in the air in the vehicle. Vehicle mounted purifier is also called vehicle purifier or vehicle mounted air purifier. It is usually composed of high-voltage generation circuit, anion generator, breeze fan, air filter and other systems.
Advantages of Car air purifier
Efficient purification mode
Get rid of the filter screen of desktop Air Purifier - passive purification mode, and the active purification mode of ion technology shows its efficient purification effect. The traditional passive purification method of combining multiple filters to firmly absorb dust can not purify every corner of the car, but ion technology can solve this problem. Spraying ions from the on-board air purifier will reach every corner of the car and play a complete purification effect.
High strength sterilization
High quality ion technology is needed to achieve high-strength sterilization. General vehicle air purifiers will adopt silver ion purification technology and low-temperature plasma technology; Some advanced will use negative ion technology and photocatalyst technology; The more advanced will use the net ion group technology.
Fashionable appearance, gifts
Nowadays, the popular style of small household appliances is no longer elegant European and American style, but simple and fashionable Japanese style. The same is true of car air purifiers. Pure color and fashionable appearance are more popular. Modern people who pay attention to practicality pay more and more attention to vehicle air purifier when choosing gifts. Whether it is a new house gift, wedding gift or business gift, the car air purifier has become the first choice.
Authoritative certification, sales assurance and perfect after-sales service
An on-board air purifier can obtain a number of international authoritative certifications and professional experimental verification, which is the recognition of its safety and purification ability by professional departments; The sales volume is the trust guarantee of the customer group; In addition, the perfect after-sales service can generally reach the level of national joint guarantee and door-to-door warranty, so it is called the perfect on-board air purifier
