the filtering efficiency is poor, and the service life is short.we are oil filter wholesale and best oil filter china,you can know it.

Carefully choose the oil filter, which is inferior

Harm of poor quality oil filter

1.The poor quality oil filter paper is poor in material, it is difficult to achieve the filtering effect required by the automobile engine, and the filter area is smaller than the original oil filter of the spare parts, the filtering efficiency is poor, and the service life is short.we are oil filter wholesale and best oil filter china,you can know it.

2.Inferior oil filters often do not have a bypass valve. Once the filter is clogged, the engine will not be able to obtain sufficient oil lubrication. In severe cases, the engine will skip the teeth, burn the tiles, or even scrap.

3.The inferior oil filter does not have the function of suppressing the oil return after the flameout. The mechanical wear of the engine during cold start is increased, and the engine life is reduced.

4.Inferior oil filter rubber seal ring material is poor, the seal ring is deformed under high temperature and high pressure, which can not effectively seal, so that the oil leaks.

Oil filter replacement tips

The replacement of oil and oil filter is a must-have item for car size maintenance. The oil and machine filter are closely related. Please pay attention to the technical things when you replace it, which can help us master the knowledge of car maintenance.

In general, we have to change the oil filter when the oil change time is maintained. This is a small car maintenance. Because it is easier to grasp the replacement cycle of the oil filter at this time, it is an effective way to keep the oil circuit clean. It is easier for us and our technicians to remember to change the time.

It is recommended to use good brand oil during maintenance, otherwise the engine performance will be greatly reduced, and a good brand oil filter is required.

Good synthetic motor oils are generally very corrosive. Using a poor oil filter will quickly erode the untreated filter paper and the filter will not work.

The use of a good oil filter, there is no such problem, and the maintenance cycle will be extended, the best in the industry is the German Man brand, but the price is more expensive, compared to the expensive maintenance costs, the machine is expensive The money is rustling.

The importance of automotive air conditioning filters

Under normal circumstances, the air conditioner filter can filter the air entering the interior of the compartment from the outside, so that the cleanliness of the air is improved, and the health of the passengers in the vehicle is ensured.

It is important to keep the air conditioner filter clean if the vehicle frequently passes through dusty roads. In the colder temperatures in winter, some car owners close the windows when driving, only open the inner circulation and do not open the air conditioner. The master pointed out that this is not correct. After a long time driving, the air inside the car will be turbid. Health brings certain hidden dangers.

During the use of the automotive air conditioning system, air flows in the blower, the refrigeration system evaporation tank, the small water tank of the heating system, and the air duct.

As soon as the air conditioning system blower is turned on or the intake mode is selected to circulate indoors, air will enter the system regardless of whether or not the refrigeration unit is used. This air accumulates a lot of dust, moisture, bacteria and other dirt on the surface of the above device during the cycle.

It lasts for a long time, breeds mold and other bacteria, emits odor, and causes damage and allergic reactions to the human respiratory system and skin, directly affecting the health of the occupants, and the air conditioning system itself may cause problems such as poor cooling effect and small air volume.

The air conditioner filter is designed to avoid the above phenomenon. It effectively filters dust, pollen and bacteria in the air and prevents contamination inside the air conditioning system.

Automotive air conditioning filters with activated carbon coating also kill bacteria in the air and inhibit bacterial regeneration. However, during the use of the air conditioning system, dust and bacteria will gradually accumulate on the air conditioner filter over time. When the air conditioner system reaches a certain level, the air conditioner system will also have the above series of faults.

Regular maintenance is required to maintain good air conditioning quality. Therefore, it is necessary to clean and regularly replace the air conditioner filter.

Filter sensor knowledge

The filter sensor mainly refers to the special sensor device for the filter on the automobile. There are many kinds of sensors, the most common ones are temperature sensor, concentration sensor, rotation sensor, position sensor, flow sensor, pressure sensor, etc. There are differences, but overall it is to ensure the normal operation of the car.

Filter sensor product features

1.The filter sensor has excellent weather resistance because it mainly works in harsh environments such as engine vibration, gasoline vapor, sludge, and water splash;

2,the performance indicators meet the standard design, the most critical of which is the measurement accuracy and reliability, otherwise the error caused by the sensor detection will eventually lead to the engine control system failure or failure;

3.The filter sensor can directly reflect the problem of vehicle running faults, minimize exhaust emissions, save fuel and promote the driving force of the vehicle engine.

Filter sensor performance indicators

1.Sensitivity: mainly depends on the manufacturing of the wafer itself. The electromechanical coupling coefficient is large and the sensitivity is high; on the contrary, the sensitivity is low.

2.Working frequency: The resonant frequency of the piezoelectric wafer. When the frequency of the alternating voltage applied to both ends thereof is equal to the resonant frequency of the wafer, the output energy is the largest and the sensitivity is also the highest.

3.Working temperature: Since the Curie point of the piezoelectric material is generally high, especially the diagnostic ultrasonic probe uses less power, the working temperature is relatively low, and it can work for a long time without failure. Ultrasonic probes for medical use are relatively hot and require separate refrigeration equipment.

Filter sensor inspection and cleaning of the filter element

1.For filter-type and felt-type filter elements, clean the filter element with clean diesel and brush to remove oil and impurities from the filter element.

2.For the paper filter type filter, after every 250~500 hours of operation, it will not be cleaned, and the new filter element should be replaced. For filters that are too dirty to be washed, damaged or perforated, they should be replaced.

3.The damage of the metal mesh filter is mainly de-soldering, damage and blockage. The maintenance method is: always maintain the filtering capacity of the filter sensor filter element. If it is desoldered, re-weld after washing, replace the new piece with damage.
