The Morning News reported that Shanghai Railway Security will be upgraded again, and the three major railway stations in Shanghai will once again upgrade the security level of major passenger stations. In addition to the previously used liquid detectors , the first batch of new handheld explosive detectors purchased by Shanghai Railway Police have been put in place. 5 seconds can accurately identify the hidden explosion hidden in the luggage. The first batch of new hand-held explosives detectors totaled 10, all imported from abroad. The unit price of the equipment was approximately RMB 600,000. Currently, they have been placed at Shanghai Railway Station, Shanghai South Railway Station and Shanghai Hongqiao Railway Station respectively. The reporter saw that the new handheld explosives detector is a black instrument with a similar shape to a dumbbell. A “card†port is set at the top and a small display is located below. When a dedicated paper jam is inserted, the instrument will be performed within 5 seconds. Read and analyze, and then judge the composition on the cardboard, if there is a dangerous component, the display turns red, and the security is displayed in green. The police can use the security inspection equipment to capture the residual components of dangerous substances that remain on the surface of the baggage or on the handle, so as to randomly and quickly examine the suspicious baggage without opening the package. It is the first time that this equipment has been placed in the National Railway Security Inspection. For the wide range of Applications of hydraulics, high temperature cooling of hydraulic oil is the key to ensure the good operation of the equipment. We have accumulated a lot of experience in design calculation and production in the 20 years of hydraulic oil cooling. Whether the unit is a Hydraulic Oil Cooler or a hybrid hydraulic Oil Cooler, we can individually customize the product according to the individual needs of the customer's industrial hydraulic equipment. At the same time, we also offer a standard hydraulic oil cooler series solution to ensure the performance at the same time. Avoid long-term problems with separate designs, and we offer different cooling drive methods for different application areas, such as hydraulic motors, DC motors, AC motors, explosion-proof motors, pneumatic motors, etc.
Hydraulic technology is also used in solar tracking systems, wave simulation devices, ship driving simulators, seismic reconstruction, rocket-assisted launching devices, aerospace environment simulations, and high-rise building anti-vibration systems and emergency braking devices.

Because hydraulic technology has many outstanding advantages, it has been widely used from civilian to national defense, general transmission to highly accurate control systems. In the defense industry. Many of the weapons and equipment of the Air Force have adopted hydraulic transmission and control. Such as airplanes, tanks, ships, radars, artillery, missiles and rockets. In the machine tool industry, 85% of the current machine tool transmission systems use hydraulic transmission and control, such as grinding machines, milling machines, planers, broaching machines, presses, shearing machines and combination machine tools.
In the metallurgical industry, electric furnace control systems, rolling mill control systems, open hearth charging, converter control, blast furnace control, strip deviation and constant tension devices all use hydraulic technology. In construction machinery, hydraulic transmissions such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibratory rollers are commonly used.
In agricultural machinery, hydraulic technology is also widely used, such as combine harvesters, tractors and plows. In the automotive industry, hydraulic off-road vehicles, hydraulic dump trucks, hydraulic aerial work vehicles and fire trucks all use hydraulic technology; in the textile industry, plastic injection molding machines and rubber vulcanizers are used. Paper machines, printing presses and textile machines; in the marine industry, the application of hydraulic technology is very common, such as full hydraulic dredgers, salvage boats, piling boats, oil production platforms, hydrofoil ships, hovercrafts and ship auxiliary machines. recent years.
