Is seat heating a safety hazard?

Recently, BMW Brilliance Automotive Co., Ltd. submitted a recall report to the General Administration of Quality Supervision, Inspection and Quarantine, which plans to recall a total of 1 to 685 BMW 520i and BMW 525i with VIN codes ranging from SA49100 to SA54937 produced between May 15 and December 17, 2004. car. The reason for this recall is that some of the heaters in the front seats of vehicles may have excessive temperature in special circumstances. The external force generated on the seat when the passenger enters or exits the vehicle is applied to the front seat back heating device, which may cause the heater on the door side to be damaged. Therefore, when the seat heater is turned on, the damaged wire will cause the heating temperature in the area to be too high to reach an unacceptable level, and may even slightly scorch the seat cover or passenger's clothes.

At present, the BMW agent Yingzhibao in the Asian Games Village stated that the company has already started recalling maintenance activities since January 4th. It is understood that Yingzhibao has so far sold a total of 20 vehicles involved in the problem, but for the convenience of the owner, regardless of whether the vehicle is purchased from the store, the owner only needs to drive to Yingzhibao to confirm the chassis number and get the recalled vehicle. Seat heating system free repair service.

It is reported that the improvement process will be carried out by professional technicians to inspect the seat heating system, confirm the failure, and perform repairs to improve the seat heating system circuit and install safety insurance. The above recall measures are completely free to the owner. However, because the inspection is first performed, the entire maintenance process takes about 3 hours. According to Yingzhibao maintenance personnel, the company's dedicated station can repair 3 BMW cars a day.

Seat heaters are not unique to high-end cars such as BMW. Many mid-range and mid-to-high-end cars in China have been increasingly equipped with vehicles in order to increase the overall cost-effectiveness of their vehicles. Seat heating has also appeared on models such as Polaris and M6. Will the same hidden dangers appear on these models? What should you watch out for in daily use?

Land Master of Beijing Class One Automotive Service Station, Jialihua Automotive Technical Service Co., Ltd., said that this should be a design issue for BMW cars and not a common issue for other brand models. The principle of car seat heating device is the use of resistance wire heating, in addition to a slight difference in workmanship, there is no excessive number of advantages and disadvantages. In general, the seat heating device is not easily damaged in addition to being subjected to an external impact, and because it is an internal device, it is troublesome to repair and is not a routine maintenance inspection item. However, Master Lu prompts the owner that when using the heating device, the time is not easy to open and the temperature should not be set too high. The owner feels that the temperature can be switched off. In addition, when the empty seat is turned on the heating device, do not place easily heat-conductive items, such as clothes, paper, etc., so as to avoid accelerating seat warming and causing an accident.

At the same time, in response to the current situation in the automotive decoration market, adding the seat device, Master Lu said that the owner is best not to install in the informal car decoration shop, if it is not a professional operation, it will easily plant hidden security problems. If the owner wants to install some kind of heating device, there is an electric blanket-like item on the market, which is placed on the seat and can be turned on. The price is tens of dollars. Although winter in Beijing is extremely cold, it is more important to be safe for the winter.

(Link mode :P tube type, FP flange, BP plate, BDP flip plate, DLP flip pipe type, DFP flip flange type, etc.)ZU-H pressure pipeline oil filter is installed on the pressure pipe of the hydraulic system to filter out the mechanical impurities mixed in the hydraulic oil and the glue, asphaltene, carbon slag produced by the chemical change of the hydraulic oil itself. Thus to prevent the valve core stuck, orifice gap and damping hole blockage and hydraulic components too fast wear and other failures. ZU-H filter has good filtering effect and high precision, but it is difficult to clean after plugging, and the filter element must be replaced. The ZU-H filter is equipped with a pressure difference signaling device. When the filter element is polluted and blocked until the pressure difference of the inlet and outlet is 0.35MPa, the switch signal is issued, and the filter element is replaced at this time to achieve the purpose of protecting the system safety.

The filter element of ZU-H filter is made of glass fiber filter material, which has the advantages of high filtration accuracy, large oil flow capacity, small original pressure loss, large pollution absorption, etc. Its filtration accuracy is calibrated by filtration accuracy, filtration ratio B3, β5, B10, β20>200, filtration efficiency n≥99.5%. The evaluation methods were IS016889-99 and GB/T18853-2002. Service life: the life of the ZU-H pipeline filter itself is not fixed, its use is very related to the cleaning of the filter, and the quality also has a lot to do with it. If you use too many environmental impurities, then the filter is more likely to inhale unclean gas, which increases the working pressure of the filter, and too much impurities will soon clog the filter element. However, do not insist on using when you find that the filter element is blocked and damaged, because fine particles of impurities will enter the lubricating oil of the system and accelerate the oxidation of the lubricating oil.
