Recently, Shandong Province took the lead in issuing small electric vehicle industry standards nationwide, and imposed restrictions on enterprise access conditions. The industry standard for small electric vehicles, which was first introduced in China, will be implemented on July 1.
The so-called small electric vehicle refers to an electric vehicle that is electrically driven, has four wheels, and has a maximum speed of no more than 70km/h. The product does not infringe on the intellectual property rights of others, and is mainly used in the limited area of ​​the second and third tier cities. This standard consists of nine parts: scope, normative references, terms and definitions, product model and technical parameters, technical requirements, test methods, inspection rules.
According to the person in charge of the Shandong Automobile Industry Association, Shandong is a small province for the production and use of small electric vehicles. In recent years, the small electric vehicle industry in Shandong Province has shown a rapid development trend. The products of a group of key enterprises have passed the test of the national automobile testing organization, and the reliability and safety have been significantly improved. The investment in the whole vehicle and key parts and components projects in the province has exceeded 15 billion yuan; the production and sales have grown rapidly, and the cumulative exports have nearly 3 Ten thousand vehicles produced 71,424 vehicles from January to May 2014, a year-on-year increase of 47.28%.
Up to now, the Shandong Provincial Government has concentrated on purchasing 1,383 small electric vehicles for three consecutive years, serving as the official vehicles for the public security, transportation, safety supervision and finance departments in the province to support industrial development. In 2012, the Shandong Provincial Government proposed that by 2015, the province's small electric vehicle production scale will reach 300,000 units, and in 2020, it will reach the development goal of 1 million units.
Despite the large market demand and considerable prospects for industrial development, the country has failed to give clear positioning for small electric vehicles, and the lack of relevant standards has brought difficulties such as difficulty in listing and difficult handling of accidents. In order to solve the damage compensation for small electric vehicle users in the process of using the vehicle, the Shandong Automobile Industry Association also issued a notice on the implementation of vehicle insurance for small electric vehicles. The notice covers insurance liability limits, insurance fees, etc. Non-motorized third-party liability insurance, traffic accident liability compulsory insurance, two small electric vehicle insurance programs and detailed procedures in various aspects such as insurance and claims.

Metal Body Square Water Cooling Tower
This series of products run stable, low noise, energy-saving, in office buildings, shopping malls, hotels, residential areas and other central air-conditioning supporting the use of better results.
The company's standard cooling tower according to the international design conditions design, can also provide customers with non-standard operating conditions or specific sizes under the special, special design.
The circulating water pump suction port shall be located below the water level of the cooling tower catchment basin, and the cooling tower outlet pipe shall not be allowed to be higher than the maximum water level of the catchment basin.
Pipe mounts should be pipe racks and cooling towers should not be allowed to directly bear the weight of the pipes.
The rehydration pipe of the cooling tower should be provided with a support stand to avoid vibration of the pipe when the float valve is rehydrated.
Rehydration pressure should be below 5m water pressure, national standard
The flannage pressure is 1.0Mpa.
When two or more units are assembled, our company will provide a connecting balance tube to balance the chassis water level. The tower top inlet should be set with a conditioning valve in order to enter each
.The water level of the tower is uniform.
The noise is measured at dm1.13VL-W at the equivalent diameter of the cooling tower (Dm1.13VL*W), 1.5 meters above the ground height, wherein L and W are the shape rulers of the tower
inch long and wide).
The use of cellular continuous blister series of diversion,heat dissipation, water collection three-in-one native filler, the whole suspension, gravity cloth water, low drop of water, with cold effect
High, low energy consumption, less drift water, less noise and so on, floating water rate is less than 0.001%.
When connecting different types of towers, the bottom basin water level height of different types of towers must be taken into account, and the base height must be adjusted to maintain the water level balance of the towers.
