cold water machine is a vapour compression or absorption cycle through the machine of refrigeration effect. The liquid to flow through the heat exchanger to reach to the purpose of the cooling air or equipment.
most plastic enterprise, is the need to use cold water machine the machine cooling, may be a lot of friends in the purchase of industrial cold water machine, often do not know with what kind of cold water machine, to meet their requirement of refrigeration effect, or that I don't know what kind of machine is more suitable for their own production workshop.
generally divided into screw cooling, cooling fuselage, and cooling of the product.
1, the cooling screw
screw cooling is to eliminate the effect of friction heat, stable plastic extrusion pressure, plastic mix, improve the quality of plasticizing. But its use must be appropriate, especially not to deserve, otherwise the barrel inside the plastic melt sudden cooling, can lead to serious accidents. And screw cooling before extrusion is absolutely prohibited use, otherwise will have serious equipment accident.
2, fuselage cooling
the fuselage cooling is to increase the effect of barrel cooling, in order to overcome the friction hot forming of warming, because the temperature in the process of plastic extrusion, also cannot stop even after power cut, so that the reasonable temperature not to maintain for a long time, must increase heat dissipation, and make the barrel cool down, in order to maintain the heat balance in the process of extrusion. Fuselage cooling is segments, mainly fan cooling, considering the function of the body paragraphs are different, the use of homogenization section cooling especially pay attention to.
3, product cooling
product cooling is to ensure that the products of geometric shape and internal structure of the important measures. Plastic extrusion cladding after leaving the nose, should immediately for cooling, otherwise it will occur deformation under gravity. For a non-crystalline materials such as PVC can not take into account the issue of crystallization, quenching method can be used plastic products, direct cooling water, in the cooling water tank cold, no longer to be out of shape. And polyethylene, polypropylene crystallization of polymer such as cooling, consideration should be given to the crystallization, if use the quench method, can bring adverse effect to plastic products group, produce internal stress, this is one of the causes of cracks of products in the future, must attach importance to it in the extrusion process. Such as polyethylene, polypropylene crystallization type plastic extrusion cladding appropriate USES gradually cooling water cooling method, generally depending on the equipment auxiliary facilities, the cooling water tank should be segmented section, water temperature can be introduced into the first section of the tank by plastic extrusion cladding temperature of 75 ℃ ~ 85 ℃, is presented. the lower water temperature, until the room temperature, paragraphs temperature the smaller the temperature difference is reasonable.
cold water machine has the following features:
1, high quality compressor in the heart of industrial cold water machine ( Origin of Europe and the United States, a new original compressor, the built-in security protection, low noise, energy saving and durable) 。
2, tank evaporator built-in automatic filling water device, save the peng bilge water tank engineering installation and convenient installation and maintenance, applicable to the large temperature difference is small flow rate and other special occasions.
3, air-cooled chiller condenser high entire punch punch, doubling piece quality is reliable. Secondary flanging, copper pipe and fin closer contact, high thermal efficiency. Adopt imported copper tube and auto bend welding; Greatly enhance the oxygen tightness, put an end to refrigerant leakage phenomenon; Especially suitable for water shortage or high hardness of water quality.
4, industrial chiller unit configuration: single configuration chip control system, the built-in compressor filter drier and expansion valve, hand valve maintenance interface device, such as to ensure the reliable safe operation of the machine, convenient for maintenance.
5, industrial cold water machine multi-function ammeter, mounted on the operation panel control system insurance, compressor switch button, switch button, electronic temperature controller, the safety protect shoulder trouble light, unit operation indicator light, the operation is simple, easy to use.
6, water cooled condenser rebar control for the use of the most efficient, heat dissipating capacity is big, small size, using the latest processing technology, CAD/CAM completed with CNC machining center, compact structure, high reliability, good appearance, high efficiency and energy saving.
7, refrigerating capacity based on 30 ℃, cooling water outlet temperature 35 ℃, frozen water in 12 ℃, out of the water temperature 7 ℃.
plastic with cold water machine, plastic industry, plastic processing machinery molding mold cooling, can greatly improve the plastic products surface finish, reduce plastic products surface grain mark and internal stress, don't make products to shrink, deformation, is advantageous for the plastic mold release, accelerate product, thus greatly improve the efficiency of the production of plastic molding machine.
