Anonymous users2024-02-11Of course, the first choice to buy vacuum pumps is Busch, the products are purely imported, the process is rigorous, the quality is supreme, stable and reliable, sturdy and durable, it is a leader in the industry, and is widely praised and favored by users. The Busch R5 oil-lubricated rotary vane vacuum pump has become the benchmark in the industry thanks to its consistent robustness and operational reliability. Worldwide, more than 3 million of these vacuum pumps are used every day in a wide range of harsh industrial applications.
If you feel that the above is not detailed enough, you can consult Busch Vacuum Equipment International (Shanghai)****. Vacuum Solutions International (Shanghai) and Vacuum Vacuum Technologies (Shanghai) are wholly-owned subsidiaries of Vacuum Solutions in China, with more than 50 years of experience in the field of vacuum pumps and vacuum systems

Anonymous users2024-02-10EH oil is simply the oil that is supplied to the DEH system.
High-pressure flame retardant and explosion-proof oil.
It is a kind of oil in the steam turbine system, which is specially used to drive the steam turbine switch to adjust the door. Because the working environment is in high temperature and high pressure, it is required to be flame resistant and explosion-proof.
Knowing what EH oil is, you know that EH oil pump is a pump that provides EH oil, and the pressure of EH oil mother pipe is generally above 12MPa, and the outlet oil pressure is adjusted by the variable head of the pump head.

Anonymous users2024-02-09The EH oil system of the steam turbine is the actuator of the steam turbine control object, including the oil motor of the control valve and the oil supply system that provides high pressure and anti-fuel to the oil engine, in addition to the critical shut-off control block (solenoid valve) and diaphragm valve and other components that control the emergency shutdown of the oil engine.
The function of the EH system is to accept the output command of the DEH control system, control the opening of the steam inlet valve of the steam turbine, change the steam flow rate into the steam turbine, and meet the requirements of the speed and load regulation of the steam turbine.

Anonymous users2024-02-08The EH oil pump is a constant pressure variable piston pump, and its constant pressure output is achieved by feedback adjustment of outlet pressure change. The regulating device is divided into two parts: the regulating valve and the pushing mechanism.
The control valve is installed on the upper part of the pump, which feels the change in the pressure at the outlet of the pump and converts it into the thrust of the pushing mechanism. The pushing mechanism is inside the pump body, and the change of the pressure signal output by the regulating valve will be converted into the change of the inclination angle of the swash plate, and the thrust generated by the piston overcomes the spring force to determine the inclination angle of the swash plate of the pump, so that the output pressure of the pump changes.

Anonymous users2024-02-06The full name of DEH system is Digital Electro-Hydraulic Control Systeern, that is, digital electro-hydraulic adjustment system, EH refers to the hydraulic part of the system, and EH oil often refers to "oil for hydraulic control system". It can be turbine oil or fuel oil resistance (because ESC units can use turbine oil or oil resistance as the oil for hydraulic control systems.) Place of use:
Speed control system of ESC unit (strictly speaking, hydraulic control system).

Anonymous users2024-02-05The EH oil of the steam turbine is the high-pressure anti-fuel of the steam turbine, which is an independent system of the steam turbine of the large unit and is used in the speed regulation system of the steam turbine. High-pressure fire resistant oil is the abbreviation of the English name of high-pressure anti-fuel oil.

The most advantageous extraction pressure should both heat the feed water to a given feed water temperature and maximize the work done by the extraction steam in the turbine. When the recuperative steam extraction is used to heat the feed water, the feed water temperature increases with the increase of the steam extraction pressure, and the thermal economy also increases. When the pumping pressure reaches a certain value, the thermal economy reaches its maximum, and the feed water temperature at this time is called the theoretical optimal feed water temperature.
This involves the principle of steam turbines, and I'll talk about it in layman's terms >>>More
