A concrete manifestation of the competitiveness of water parks

 

With the continuous improvement of people's living standards, the state promotes the development of the cultural and tourism industry. After more than 30 years of continuous development, China's water park market is booming, and the industry has seized the development opportunities to step up its deployment. At the same time, investors and operators have become more and more rational in thinking about water parks. The advantages of a successful water park include IP packaging, theme activities, tourist services, water park equipment, catering and other ancillary facilities, comprehensive tourist experience, etc. The most important of these is the current experience that can bring visitors an intuitive amusement experience. It belongs to the water park equipment, which largely determines the passenger flow, the repeat visit rate of tourists, and the operating cost.

With the increasing investment and requirements of Chinese consumers for amusement experience and services, how can they stand out in the market all over the water park and gain a long-term competitive advantage? That is, the water park needs to introduce distinctive amusement facilities to create differentiation and attract target customers.

Mainly consider several aspects:

1. Innovative

Unique and innovative water park equipment is the key to attracting tourists and bringing repeat customers. The truly innovative water slide products can bring visitors a unique amusement experience that cannot be replicated by other similar slides, leaving an indelible impression in the hearts of tourists.


2. Quality and performance

Water amusement facilities must not compromise on quality and performance requirements. A high-standard water slide must have a better experience for tourists, a safer and controllable taxi route, a more durable FRP material, a smoother operation, and a lower maintenance cost.


3. Return on investment

The cost of designing and purchasing water slides for water parks only accounts for about 20% of the total investment in the new park. Those water amusement facilities that integrate industry-leading innovation, technology and high-quality water amusement facilities can create 70% for the park in the long run. %-80% of operating income.


4. After-sales service

Excellent after-sales service will help the water park to operate more efficiently. Through reasonable maintenance, the life of a water slide can reach at least 20 years. Building a successful, popular, and uniquely differentiated water park can gain a competitive advantage in the regional market for a long time in the future. This is also a new trend for China's water parks in the future.

What is Cake Showcase Chiller

Cake display chiller or cake showcase refrigerator are refrigerated and fresh-keeping cabinets used to display cakes. They are usually made of stainless steel and marble. They are often used in cake shops, food stores, etc., and have a wide range of uses. 

There are two types of cake display chiller: direct cooling and air cooling. The temperature is 2~8 degrees to keep fresh. There are various styles such as arc, right angle, front sliding door, etc.

In order for the cake showcase refrigerator to have a variety of purposes such as preservation, refrigeration, display, etc., the overall structure of the cake showcase refrigerator also uses all detachable and installable parts, all of which are made of tempered glass, which guarantees the display effect and ensures when the glass is broken will not hurt people.The cake display chiller also own movable casters for easy mobility.

The difference between EFI and ESC for diesel engine

 

1.What is EFI diesel engine


An electronically controlled diesel engine( for genset power in thailand) is an electronically controlled diesel engine that controls fuel injection and emissions. The EFI diesel injection system consists of a sensor, an ECU (computer) and an actuator. Its task is to electronically control the fuel injection system to achieve real-time control of the fuel injection quantity and fuel injection timing with operating conditions. Using speed, fuel injection time, intake air temperature, intake air pressure, fuel temperature, cooling water temperature and other sensors, the real-time detected parameters are input into the computer (ECU) at the same time, and the stored set parameter values or parameter map (MAP map) ) For comparison, after processing and calculation, the instruction is sent to the actuator according to the good value or the calculated target value. The actuator controls the fuel injection amount (solenoid valve closing duration) and injection timing (timing control valve opening and closing or solenoid valve closing start point) according to the ECU instruction, and simultaneously controls the exhaust gas recirculation valve, glow plug and other actuators In order to make the diesel engine running condition is good.


2.The difference between EFI and ESC


In terms of speed regulation, EFI and ESC belong to the category of electronic speed regulation, which is different from the mechanical speed control method. However, there is an essential difference between the fuel injection control method and the speed control control execution method, which can be compared in the following aspects:


2.1 Fuel injection pressure


The ESC injects diesel directly into the cylinder through a traditional high-pressure pump. Its injection pressure is limited by the pressure valve on the injector. When the fuel pressure in the high-pressure fuel pipe reaches the set value of the pressure valve, the valve is directly injected into the cylinder. Inside, the pressure of the pressure valve affected by mechanical manufacturing cannot be very large.


The electric injection machine first generates high-pressure oil in the high-pressure oil chamber of the injector by a high-pressure oil pump. The fuel injection of the injector is controlled by a solenoid valve. When fuel injection is needed, the electronic control system controls the solenoid valve to open and inject the high-pressure oil into the cylinder. The pressure of high-pressure oil is not affected by the pressure valve and can be increased a lot. The diesel injection pressure is increased from 100MPa to 180MPa. Such a high injection pressure can significantly improve the quality of diesel( for hoe to mount wrartsila diesel engin generator) and air mixing, shorten the ignition delay period, make combustion faster and more thorough, and control the combustion temperature, thereby reducing exhaust emissions.


2.2 Independent injection pressure control


The injection pressure of the high pressure oil pump fuel supply system of the ESC is related to the speed load of the diesel engine generator on cruise ship. This characteristic is detrimental to fuel economy and emissions at low speeds and part load conditions. The fuel injection system of the EFI engine has an injection pressure control capability that does not depend on the speed and load. You can choose the appropriate injection pressure to make the injection duration and ignition delay period better, so that the diesel engine's exhaust emissions under various operating conditions are low and economical. high quality.


2.3 Independent fuel injection timing control


The high-pressure pump of the ESC is driven by the camshaft of the engine, and its injection timing directly depends on the rotation angle of the camshaft. After a machine is adjusted, its injection timing is fixed and the injection timing of the EFI machine is completely The solenoid valve is controlled by the electronic control system to adjust. Instead of relying on the injection timing control ability of the machine to rotate, it is a key measure to achieve a good balance between fuel consumption and emissions. Experts have studied for many years and found that different injection times under different load conditions are required to produce optimal s efficiency.


2.4 Fast oil cut-off capability


The fuel must be cut off quickly at the end of the injection. If the fuel cannot be cut off quickly, the diesel injected at low pressure will emit black smoke due to insufficient combustion and increase HC emissions. The high-speed solenoid on-off valve used in the EFI diesel injector is easy to achieve quick oil cut. The high-pressure oil pump of the ESC cannot do this.


2.5 Execution mode of speed control


The electric governor is a governor that feedbacks the speed signal of the machine through a speed sensor. The governor compares the preset speed value and converts the difference into a governor signal to drive the actuator to control the oil supply rack or sliding sleeve. To achieve speed regulation, the fuel supply signal simply depends on the speed signal, and the adjustment of the fuel supply amount is achieved by the mechanical action of the actuator. EFI uses sensors such as speed, injection timing, intake air temperature, intake air pressure, fuel temperature, and cooling water temperature to input the parameters detected in real time into the computer (ECU), and the stored parameter values or parameters. The map (MAP map) is compared, and after processing and calculation, the instruction is sent to the actuator (solenoid valve) according to the good value or the calculated target value.
