The latest spot check disclosed by the State Administration for Industry and Commerce today showed that the sampling rate of automotive brake hoses was 50%. Among them, 11 samples of hydraulic brake hoses were sampled, the sampling pass rate was 54.5%, and 5 samples of pneumatic brake hoses were sampled. The sampling pass rate was 40%. According to the State Administration for Industry and Commerce, the auto parts market is in urgent need of rectification.
The automotive brake hose assembly is a key component of the automotive brake system. It transmits brake pressure in the system and drives the brake to produce the service brake. Its quality is directly related to the life and property safety of drivers and pedestrians. In order to strengthen the supervision and management of the quality of automotive brake hoses, the State Administration for Industry and Commerce recently proposed 16 types of automotive brake hoses for 16 auto parts distribution companies in 6 auto parts cities in Beijing, Wuhan, Changchun and Tianjin. Supervised spot checks were conducted and 8 kinds of qualified products were passed. The sampling pass rate was 50%.
Among them, 11 samples of hydraulic brake hoses were sampled, the sampling pass rate was 54.5%, and 5 samples of pneumatic brake hoses were sampled. The sampling pass rate was 40%.
Spot checks found the main problems are: - ozone resistance indicators failed. The ozone resistance index does not meet the requirements of the national standards. In actual use, the hose will rapidly age and crack, and its burst strength and tensile strength will be reduced. When the brakes are broken, the hose may burst and the braking failure may occur. The tragedy that caused the crash of the car. Of the 16 products that were sampled, 8 were unacceptable for ozone resistance, accounting for 100% of the total number of unqualified products.
- Rejected bore hole throughput indicators failed. After reducing the diameter of the internal hole through the amount of national standards can not meet the requirements, in actual use will affect the transmission of brake fluid displacement, brake brake torque, and the strength of the hose itself will be reduced, when the brake The same failure or failure will occur. Of the 16 types of products that were spot checked, there were five kinds of unsatisfactory through-diameter internal hole throughput indicators, which accounted for 62.5% of the total number of unqualified products.
- Unsatisfactory tensile strength indicators. The three test items of through-bore diameter, burst strength, and tensile strength have a correlation to some extent. Of the 16 products that were spot checked, 3 were unsatisfactory in the tensile strength index, accounting for 37.5% of the total number of unqualified products.
The commodities and industry and commerce departments found to have failed to comply with the mandatory standards found in the random inspections have ordered the distributors to withdraw the counters and cannot continue to sell. For the distribution agencies that have serious quality problems and distribute counterfeit and shoddy goods, they strictly investigate and punish them after investigating the case.
It is understood that there are hundreds of manufacturers of automotive brake hoses in the country, with an annual output of 4 million. However, the quality of products varies greatly, especially in the auto parts market where counterfeit and shoddy problems are prominent, and there are significant driving safety risks.
The State Administration for Industry and Commerce reminded consumers that they should try to purchase goods from the designated maintenance department or sales department of a car manufacturer. When purchasing goods, you can ask the distributor to inspect the product inspection certificate, and do not purchase products with outdated appearance, no product identification, or unclear product identification.
Characteristics:
1.Reusable. Using solar energy stored in earth as cooling & heating source.
2.Great environmental and economic benefit, No boiler or cooling tower; less space, less CO2 and less initial investment.
3.Acting as multi-function unit. Such as cooling, heating, sanitary hot water separately or simultaneously.
4.Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc.
5.Semi-hermetic screw compressor for mod.130 to 2500. Each compressor is equipped with a crankcase heater and a thermal overload cut-out; the screw compressor is also complete with a built-in electronic protection with temperature sensor located directly in the motor winding and on the discharge line.
6.The refrigerant circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch.
7.Shell and tube dry expansion type condenser, factory insulated with flexible close cell material. Shell and tube type evaporator, factory insulated with flexible close cell material.
8.The electric panel consists of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker, microprocessor control with function display.
9.LCD display, touch screen control panel as standard. Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.
10.For the units with semi-hermetic screw compressor, an infinitely variable capacity control system that is capable of exactly matching the demand requirement of the system is to be supplied. This system is to provide precise and stable control of supply water temperature over the complete range of operating conditions.
11.OPTIONAL
