On August 13, it was learned from Hangzhou Westlake Electronics Group that the first batch of 300 boxes of new-generation fast-changing battery boxes independently developed by Xihu Electronic Group had entered the private rental electric vehicle replacement station system in Hangzhou, of which 140 sets of battery boxes had entered each Change station. West Lake Electronics related person in charge, this year in July, this named BL-8063JA-type pure electric passenger car quick change battery box through the National Motor Vehicle Product Quality Supervision and Inspection Center (Shanghai) certification, becoming the first pass in Zhejiang Province State-authority inspection agency certified power battery group products. In August, the first batch of 300 boxes of new-generation quick-change battery boxes were put into operation, among which 140 sets of battery boxes entered various transformer stations.
"The pure electric car has no electricity. You don't need to spend three or five hours to recharge. Simply switch to a nearby charge station and replace it with a new one for about 10 minutes," said Zhang Ping, spokesman for Xihu Electronic Group. The first batch of 30 citizens who have leased electric cars privately has been able to replace a new generation of fast-changing battery boxes at various substations in Hangzhou. The use of a new generation of electric vehicles in electric vehicles, full power can exercise about 80 kilometers, compared to the first generation of batteries, driving mileage increased by more than 30%.
It is understood that Hangzhou, as a "double pilot" city for national new energy vehicles, is the first large-scale city to implement large-scale "exchange mode" operation in China and even in the world, in addition to the first practice and promotion of "private leasing" business model. .
According to related technical personnel, if the temperature, voltage, and current of the power battery are abnormal, the back-end system developed by the group can clearly know where each rental car is located, how much power it has, and whether the battery performance is normal. Such as, to facilitate the timely detection of problems, and push the information to the owner.
It is understood that, in addition to the battery industry, the West Lake Electronics Group plans to build a "smart charge station" integrating the functions of a three-dimensional garage and a charge-and-replace power station at the end of this year.
There are many types of valves, such as hydraulic valves, globe valves, overflow valves, cleaning valves, gate valves, butterfly valves, ball valves, etc.
We are good at processing heat-treated valve core and valve sleeve, end cap and piston rod and other parts
The hydraulic valve is an automatic component operated with pressure oil. It is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with an electromagnetic pressure distribution valve. Commonly used in oil circuits such as clamping, control and lubrication. There are direct acting type and pilot type.
The spool is a valve part that realizes the basic functions of directional control, pressure control or flow control by means of its movement.
Shut-off valves, also known as gate valves, are forced-sealed valves, so when the valve is closed, pressure must be applied to the clapper to force the sealing surface to not leak. When the medium enters the valve from below the clapper, the resistance to be overcome by the operating force is the friction force between the stem and the packing and the thrust generated by the pressure of the medium. The diameter should be large, otherwise the failure to bend the valve stem will occur. According to the connection method, it is divided into three types: flange connection, screw connection and welding connection. After the appearance of the self-sealing valve, the medium flow direction of the shut-off valve is changed into the valve cavity from above the valve flap. At this time, under the action of the medium pressure, the force of closing the valve is small, and the force of opening the valve is large, the diameter of the valve stem can be corresponding To reduce. At the same time, under the action of the medium, this form of valve is also relatively tight. China's valve "three chemical" once stipulated that the flow direction of the globe valve should be top-down. When the cut-off valve is opened, the opening height of the valve flap is 25% to 30% of the nominal diameter. The flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the shut-off valve should be determined by the stroke of the disc.
