60 Ton water cooled screw chiller for extruder process

60 Ton water cooled screw chiller for extruder process

In the process of industrial production in which the extruder participates, the cooling water tank of the extruder absorbs a large amount of heat from the extruded parts, and the temperature rises quickly. If refrigeration and cooling equipment is not installed, the water tank of the extruder will not meet the cooling requirements, which will seriously affect the quality of the extruded parts.

To reduce the temperature of the cooling water tank of the extruder, the problem of excessively high temperature of the cooling water tank of the extruder can be solved only by installing an extruder chiller.

The chiller for cooling the extruder is called an extrusion chiller. Also called plastic extrusion cooling system. Since the extruder is mainly used for various extruded plastic products, such as PE, PP, PVC, ABS, etc., the high temperature generated during the production process will cause difficult demolding and slow molding, so a chiller is required to provide low-temperature cycle freezing Water (5-30°C) is fed to the extruder to shorten the cooling time and improve product quality.

The extruder chiller is a kind of cooling water equipment that can provide constant temperature, constant current and constant pressure. The working principle is to first inject a certain amount of water into the water tank in the machine, cool the water through the refrigeration system of the industrial refrigerator, and then send the low-temperature cooling water to the equipment that needs to be cooled by the water pump, and the chilled water of the refrigerator will take away the heat after the temperature It is raised and then returned to the water tank to achieve cooling. The cooling water temperature can be automatically adjusted according to requirements, and long-term use can save water. Therefore, it is a standard energy-saving refrigeration equipment.

When choosing a chiller for the extruder, you should pay attention to the following points: First, we must confirm whether the customer’s extruder has an open sink, if so, when choosing a chiller, you should choose a shell-and-tube type or a plate Replace the evaporator instead of the water tank coil type evaporator. If there is no sink or pool, you should choose a water tank coil type evaporator.

The second is the selection of the extruder. When selecting a chiller, we must calculate the chiller power based on the temperature of the water in the extruder tank, the amount of water used per hour, and the temperature of the return water. As the heat generated by the extruder in a short period of time is relatively large, in order to ensure the cooling effect, a slightly larger value is generally selected, which can avoid the full-load operation of the chiller and ensure the stability of the cooling.

The last is the selection of the cooling type of the chiller. Many customer factories are equipped with cooling water towers. In this case, it is better to choose a water-cooled chiller. The water-cooled chiller uses the water tower to dissipate heat and has higher cooling stability; if there is no cooling water tower and the cooling power of the chiller is low, it is recommended Use air-cooled chillers; users with higher cooling power (such as 40hp 50hp chillers) should use water-cooled chillers with cooling towers for cooling.

Extrusion chiller Product display

The chiller for extrusion production lince includes four main components of the vapor compression refrigeration cycle (compressor, evaporator, condenser, circulating pump), these machines can realize different refrigerants. Compression refrigerators use refrigerants as refrigerants to achieve a strong affinity for refrigeration effects.

1. The extruder chiller adopts fully-sealed, low-noise, low-vibration, high-efficiency and power-saving imported brand-name compressors, all electrical control adopts imported original parts, and the heat exchanger adopts a shell and tube condenser, which has high heat exchange efficiency and is easy to clean and maintain .

2. Energy-saving and economical: The digital electronic thermostat can accurately control the temperature of cold water between +3℃ and 50℃, thereby controlling the normal operation of the unit, saving energy, and all the unit assembly, internal wiring, refrigerant filling and debugging are all in The factory is over.

3. Safe operation: The machine body is equipped with compressor delay starter, overcurrent relay, high and low pressure device, fuse plug, electronic time safety valve, to ensure the normal operation of the unit.

4. Condenser: High-efficiency threaded steel pipes are used. Both ends of the cover can be interchanged to change the direction of the water pipe. The water pipe process is multiple times. Each condenser is matched with the compressor capacity. The straight-through water pipe is easy to clean and maintain.
