The heating element give off the far infrared energy waves directly, heating the whole environment, people and objects. The electric infrared heating panels can be built with high thermal insulation material, so that the heat can be stored and still release within a certain time after the power outage. It is much more safe and efficient. This is a new concept of healthy and comfortable heating way.

2CY gear pump working principle and structural characteristics
2CY gear pump for transporting a variety of lubricating liquid, not suitable for conveying corrosive, hard particles or fibers, highly volatile or low flash point liquid, such as gasoline, Stupid and so on. Xiao Bian to introduce 2CY gear pump working principle and structural features. 2CY-type gear pump First, 2CY-type gear pump works 2CY gear pump in the pump body is equipped with a pair of revolving gears, one active, one passive, relying on the two gears intermeshing, the pump within the entire working chamber is divided into two Independent part. A into the suction chamber, B for the discharge chamber. During driving, the driving gear drives the driven gear to rotate, and a partial vacuum is formed on the suction side (A) when the tooth is engaged or disengaged, and the liquid is sucked in. The suctioned liquid fills each tooth valley of the gear to the discharge side (B). When the gear enters into engagement, the liquid is pushed out to form a high-pressure liquid and is discharged outside the pump through the discharge port of the pump. Second, 2CY-type gear pump structural features 1.2CY gear pump is a horizontal rotary pump, the main pump, gear, bearing seat, safety valve, bearings and seals and other mechanical components. 2. Pump body, bearing seat and so on are made of gray cast iron. The gear is made of high-quality carbon steel. It can also be made of copper material or stainless steel according to user's special needs. 3. The bearing seat has a stuffing box, axial sealing effect. 2CYl00 / 3, 2CYl20 / 3, 2CYl50 / 3, KCB a 300 ~ 960 pump skeleton seal device. Bearings using single row radial ball bearings. KCB a 18.3 ~ 83.3-type pump with three oil-resistant rubber ring and the middle of the lining of a ring, adjust the two cap screws to adjust the degree of sealing, bearings using copper-based powder oil bearing. In addition, this series of pumps can be filled with packing to flexible, high temperature and low temperature, chemical stability and self-lubricating flexible graphite as a filler. 4. Pump equipped with safety valve, when the pump or discharge pipe failure or mistakenly shut the valve completely closed to produce high pressure and high pressure impact safety valve will automatically open, remove some or all of the high pressure liquid back to the low pressure chamber, which Pumps and pipes play a safety role. 5. With flexible coupling directly connected with the drive motor, and mounted on a common cast iron chassis.
