The following is the relevant introduction about EH oil system: 1. Introduction: The EH oil system of steam turbine is the speed regulating oil system of steam turbine, also known as high pressure fire-resistant oil system, mainly because the speed regulating oil system and lubricating oil system of steam turbine are independent of each other, using high temperature resistant fire-resistant oil (EH oil), and adopting high oil pressure to control the main steam valve and speed regulating valve of steam turbine, so it is also called EH oil system of steam turbine. 2. Composition: EH oil supply system is mainly composed of EH oil tank, EH oil pump, inlet and outlet valve, filter screen, control block, overflow valve, accumulator, EH oil supply and return pipe, oil cooler and a set of self circulating oil filtration system and self circulating cooling system.

What are the reasons for water leakage under the Sonata water pump?

The reasons for water leakage under the Sonata water pump: 1. The axial movement of the water pump rotor is large, and the interference between the auxiliary seal and the shaft is large, so the moving ring cannot move flexibly on the shaft. After the pump rotates and the static and moving rings wear out, the compensation displacement cannot be obtained, resulting in water leakage; 2. Insufficient lubricating oil on the sealing surface causes dry friction or scratches on the sealing end face, leading to water pump leakage; 3. The stator is not aligned with the upper and lower end covers, or the impeller and the main shaft are unbalanced, causing cavitation or bearing damage. This situation will shorten the sealing life and cause leakage. The length, width, and height of the Sonata are 4747mm, 1820mm, and 1440mm respectively. In terms of safety configurations, the Sonata comes standard with dual front airbags, side airbags, ABS plus EBD, ESP electronic stability system, emergency braking reminder system, tire pressure monitoring, and rear parking radar.

What are the reasons why the car key does not respond when pressed?

When the car key does not respond when pressed, it may be due to the key fob battery being dead or interference from a magnetic field. Another possibility is that the car's anti-theft system has been activated. Once the anti-theft system is activated, the car cannot be unlocked using the key. The owner can use the mechanical key on the remote key fob to unlock the car. Generally, the mechanical lock on the car door is hidden. By using the mechanical key to pry off the outer shell of the door handle, the hidden mechanical lock can be revealed. If the key fob battery is dead, the owner can replace it themselves. First, remove the mechanical key and locate the gap in the plastic casing. Use the mechanical key to open the remote key fob along the gap. During this process, be careful not to damage the internal circuit board, as it is very small and cannot be repaired if damaged.
