products link:  https://www.accurcnc.com/qc11k-swing-steel-shearing-machine_p15.html The plate shearing machine is a kind of equipment that uses the upper and lower cutting edges to cut the plate material. Its movement process is shown as follows: under the condition of selecting the appropriate blade clearance, the metal plate material is fixed on the lower knife seat, and the plate material is cut through the upper cutting edge, so that the plate material is broken and separated according to the actual size. When cutting metal sheet metal, there are mainly three kinds of forging press, which are cutting edge forging press, cutting head forging press and cutting tail forging press respectively.In the actual production process, the shears can effectively cut different length, different thickness and different materials of metal sheet, so it is widely used in construction, light industry and metallurgy. In the process of sheet metal cutting, the pressure of ...

Methods of Washing and Descaling of Condenser

The Air cooled scroll chiller condenser is prone to scale formation after long-term using. If it is not washed of in time, the incrustation scale will affect the effect of heat-change , resulting in an increase in the condensing temperature of the chiller, which will result in a decrease in cooling capacity and an increase in chiller power consumption. Therefore, the condenser should be frequently cleaned of scale. There are three main methods for preventing and cleaning scale: 1.Mechanical descaling method: Mechanical descaling is a method of descaling a condenser of a steel cooling pipe with a soft shaft washer, and is particularly suitable for a vertical shell and tube condenser. 2.Chemical pickling and descaling method: The condenser is cleaned with the prepared weakly acidic descaling agent to make the scale fall off and improve the heat transfer efficiency of the condenser. 3. Electromagnetic water descaling method: The working principle of the electronic magnetic water device ...
