Recently, the Quality Supervision Bureau of Shijiazhuang City of Hebei Province supervised and inspected the implementation of the new regulations for the automobile three guarantees within its jurisdiction. As a result, it was found that there were 139 auto 4S shops in the city, and the purchase inspection and acceptance system was established and implemented. The repair record filing system was established and executed for the repaired vehicles, and the seller’s obligations in the “Three Guarantees Regulations for Automobiles†were fulfilled. The 18 three-pack disputes were properly handled.
In the supervision and inspection of the implementation of the three-package of the automobile 4S shop, the law enforcement personnel mainly carried out supervision and inspection from the establishment of the enterprise three-package system, the effective implementation of the three-package system, and the popularization of the three-pack knowledge of after-sales staff. The key inspections of 3C compulsory certification products and industrial product production licenses for automobile parts, automotive V-belts, brake linings (brake pads), and automotive batteries are examined. During the inspection, the law enforcement officers of the bureau earnestly publicized and implemented the relevant provisions of the “Regulations on the Repair, Replacement and Return of Household Carsâ€, collected relevant information, and urged the implementation of relevant rules and regulations.
In response to the investigation, it was found that the implementation of the three-package implementation system of individual automobile sales enterprises was unreasonable, and the personnel training was not in place. Law enforcement officers actively communicated with the company’s responsible persons and guided the company’s staff to understand the Three Guarantees policy to help them rectify the problems found. .
The relevant person in charge of the bureau said that through inspection, it can not only urge enterprises to implement the main responsibility of product quality, but also provide protection for creating a fair competitive market environment and protecting the legitimate rights and interests of consumers of household car products.
Plate And Frame Heat Exchanger
Removable Plate Heat Exchanger (RPHE) is a type of heat exchanger composed of a series of plates which are held together with gaskets. The plates are connected in a plate pack that forms a sealed Pressure Vessel. The plate pack is assembled between a fixed frame plate and a movable pressure plate and is compressed by tightening bolts.
RPHEs are quite efficient as they have a large surface area compared to other heat exchangers. Heat transfer within the heat exchanger occurs between the plates and the fluids that flow through them. One fluid flows through the plate openings in each of them, and the heat transferred is determined by the size and number of plates in the exchanger. The heat -exchanging process is repeated in each of the plates and the collected heat is transferred to the other fluid.
Plate and Frame Heat Exchangers have proved beneficial in the food and beverage industries where they are used to maintain a safe temperature during the processing and storage of foods. In addition, they are used in chemical manufacturing to cool the various chemicals that are used in this industry.
