One type of cooler of hydraulic press is tube type. There are many kinds of double tube type, vertical type, horizontal type, floating head type, etc. This type is characterized by a flow of water for cooling through the inside of the tube an interval of oil through the column. The middle folding plate allows the oil to deflect. It uses two even four channel flow method. Its cooling effect is stronger.
The tube cooler consists of two parts: the shell the internal cooler. Due to different structural methods, external connection forms are divided into pipe thread type flange type. It can be divided into horizontal type vertical type in terms of installation form, floating disc type floating head type in terms of floating form, spiral type finned tube type in terms of floating form, baffle structure can be divided into various structural forms, such as bow baffle, rectangular baffle, double weir baffle circular baffle, which are optional according to specific conditions.
The shell includes: cylinder, water distribution cover return water cover. It is equipped with inlet pipe outlet pipe as well as inlet pipe outlet pipe, as well as oil drain, drainage, vent plug, zinc rod mounting hole thermometer interface.
The main body of cooler is composed of cooler pipe, fixed orifice plate, movable orifice plate, baffle plate, etc. The two ends of the cooling pipe are respectively connected to the fixed orifice plate the movable orifice plate, the oil leaks inside the cooler; the fixed orifice plate is connected with the external flange, the movable orifice plate can expand freely outside, so as to eliminate the influence of the temperature on the cooler pipe on the thermal expansion cold contraction. Baffles enhance heat transfer support the cooler tubes.
The hot medium of the tube cooler flows through the inlet of the tube on the cylinder, then flows to the outlet of the tube through the baffle channel. The cooler medium flows in a double pipe way, that is, the cooler medium enters half of the cooling pipe through the water distribution cover through the water inlet, then flows into the other half of the cooling pipe the return cover. Insert the water cover the other side of the water outlet. The cold medium absorbs the residual heat released by the hot medium in the process of double pipe flow, is discharged through the water outlet to keep the working medium at the rated working temperature.
