      Application of capillary tube mats work in raising chickens and ducks.        Temperature, humidity, fresh air is the farm very important 3 index. At present the vast majority of chicken house, duck house is to open the window to adjust the temperature and humidity inside the house as the main means to ventilation, by the quantity of doors and Windows of open and close, and the length of time to control ventilation. Temperature, humidity, fresh air is the farm very important 3 index. At present the vast majority of chicken house, duck house is to open the window to adjust the temperature and humidity inside the house as the main means to ventilation, by the quantity of doors and Windows of open and close, and the length of time to control ventilation.   The temperature and humidity required by chickens and ducks are different at different week ages. With the increase of week ages, the ambient temperature and humidity required by chicke...

How to use electric control valve in boiler system          Electric control valve is mainly used to adjust boiler feed water , control boiler steam and cooling water pressure, temperature and flow. It is an important part of the automation control system.         The electric control valve shown in the figure is a desuperheating water regulating valve used in a waste heat recovery boiler in a metallurgical sintering plant.         This is an intelligent non-invasive electric control valve with various protection functions, receiving and feedbacking 4-20mA current signals. The performance is stable and the products sell well all over the world.       Non-intrusive electric globe control valve have electronic controls located in a separate sealed enclosure within the actuator. Position and torque limits can be set without opening the control compartment, Non-intrusive actuators allow adjust...

                       How to use capillary tube mats  in mariculture                                 www.bellauta.com Temperature control is a key technology in industrial sea cucumber breeding . At present, the boiler is often used to heat seawater and extract groundwater as the cold source to control the temperature of aquaculture water. This method is not economical and is not conducive to energy conservation and environmental protection   As a new temperature control method, capillary tube mats temperature control technology has the advantages of high efficiency, energy saving, economy and environmental protection. At present, capillary tube mats technology has been widely used in the HVAC  system of buildings. Similarly, the application of capillary tube mats technology in the heating and cooling of water for sea cu...

What is the electric actuator ?           The electric actuator is the terminal control unit of the automatic control system. It receives the signal from the central control room. It automatically controls the opening of the Valve or the Damper to achieve the automatic control of the temperature, flow, and pressure.  It is composed of reducer, motor, and electrical controller.            Electricactuators can be divided into three categories;           1: Quarter turn Actuator   2: Linear Actuator   3: Multi-turn Actuator    A: Quarter turn electric actuator is mainly used to control butterfly valve , ball valve , air valve, plug valve and other quarter-turn rotary valves            B: Linear electric actuator is mainly used to control single seat, double seat and sleeve control valve ...

                     How do Electric actuator work for the bellows of sintering machine Tianjin bell actuator   bell-400  is used in a 420 square meter sintering machine. It  uses  the negative pressure generated by the operation of the main exhaust fan to burn the flame ignited on the material layer surface of the sintering machine   trolley. As the trolley moves, the mixture on the trolley is burned until the end of smelting.         There are 21 bellows under the sintering machine trolley. The air flow in the bellows can be controlled manually and remotely. When the sintering material on the trolley arrives, the bellows below shall be opened. When the mixture is full on the trolley, the bellows shall be fully opened. Because of the negative pressure state, the combustion layer on the material surface burns down until it reaches the end point of sintering, and the sintering proces...

The sintering is evenly placed on the sintering machine, ignited, and sent to the ring cooler for cooling after sintering. The cooled particles are screened out to be qualified particles, and the qualified particles (sinter) are sent to the blast furnace for smelting.  2 A pplication of Tianjin BELL electric actuator in sintering     Tianjin bell actuator bell-400 is used in a 420 square meter sintering machine. It uses the negative pressure generated by the operation of the main exhaust fan to burn the flame ignited on the ...
