Features:
It is based on the SRY2 ordinary tubular electric heater, it improved its wiring device and heating structure, using three heating tubes as a group, effectively reducing the heater surface load, can directly replace the SRY2-SRY4 type heating Use.
The electric heater is formed by welding a bent shaped tubular element on a flange, and the heater is directly heated in the oil to have high thermal efficiency and long service life.
Overview and working principle
Flange type electric heater (also called plug-in type electric heater): U-shaped tubular electric heating element is used. According to the design specification of heating different media, it is assembled on the flange cover according to the power configuration requirements, and the material to be heated is inserted into the heating element. The large amount of heat emitted by the work is conducted to the heated medium to increase the temperature of the medium and achieve the required process requirements. When the medium temperature reaches the set value of the process requirements, the control system adjusts the output power of the electric heater after the PID operation according to the temperature sensor signal to achieve temperature control of the resistive load of the heating element. The temperature of the medium is even and reaches the required requirements. When the heating element is over-temperature or low-level, the interlock protection device of the heating element immediately cuts off the heating power to prevent the heating element from being burned out and prolong the service life.
Introduce
It is mainly used for heating in open, closed solution tanks and circulating systems. Has the following advantages:
The surface power is large, so that the air heating surface load 2 to 4 times.
Highly dense and compact. Because of the overall short and dense, the stability is good and no bracket is required for installation.
Most of the combined type adopts argon arc welding to connect the electric heating pipe to the flange, and also can use the form of fastening device, that is, each electric heating pipe is welded by a fastener. Then lock it with the flange cover using a nut. The tube is welded with argon arc welding and never leaks. The seals of the fasteners use scientific processes. Single replacement is extremely convenient, which greatly saves future maintenance costs.
Choose imported and domestic high quality materials. Scientific production process, strict quality management, ensure the superior electrical performance of the heating pipe.
Application area
Flange type electric heater is mainly used for heat preservation and heating of various kinds of storage tanks, containers and fuel tanks in petroleum, chemical, food, machinery and other industries. Connections can be flanged or threaded face seals.
Pit Balls
Pit balls are one of the toys of children's playgrounds. They can also be used in places such as Inflatable Swimming Pools, inflatable castles, water parks and field activities, which can bring wisdom and fun to children.
Pit ball uses two per porvis blowing techniques. Ball has pores, but the pores are all in the mold, and the pores are very small. Due to the production of plastic at high temperatures, when the plastic began to melt at high temperature, when it flowed to the mold ball cup, it instantly fixed the mold, instantly blown air, opened the mold, and naturally formed a spherical shape.
If you observe carefully on the sphere, there are traces of tiny bleaching holes, but this does not affect the safety of the product.
The Inflatable Toys played by children pay more attention to safety issues. The sphere is tight and not leaked, and it will not explode in the play.
