High pressure foaming machine is hard bubble or semi hard foam (one of the preferred equipment such as furniture, refrigerators and freezers in the production line. The foaming quality will directly affect the refrigeration effect and the strength of the refrigerator, and high pressure foaming machine is an important foundation for providing excellent foaming. The composition of high pressure foaming machine is mainly composed of a raw material tank, variable pump, high and low pressure change-over valve, a mixing head, hydraulic station, metering system and electricalcontrol system.
High-pressure polyurethane foam is also called PU high pressure foamingequipment, PU is the abbreviation of the Polyurethane English. The English meanspolyurethane formate, also referred to as polyurethane. PU foaming equipmentconsists of two components, the first component is a polyol, isocyanate component B, operating two component into the mechanical mixing jet, in a mist shape, foamingsolidification. Commonly used in furniture foam (instead of Fraxinus mandshurica Rupr), refrigerator foaming, garage door foaming, aluminum foam, thermal insulation building waterproof etc.. The use of a very wide scope.
Equipment technical parameters and configuration:
1, injection flow rate: 100 ~ 500g/sec.
2, mixing ratio: 1:1 ~ 1:3 adjustable.
3, measurement system: the frequency control motor with Beijing gelanlishi inletpump and electromagnetic coupling coupling:
The rotation speed of the motor power: 5.5/kw, 1450/min, voltage: gelanlishi pump 380V50Hz. using high accuracy with the discharge spits out the amount of precisionto 0.001 grams of error. The main function of electromagnetic coupling coupling to ensure that raw materials do not leak.
4, high-pressure mixing head: L piston type mixing head, has the advantages ofgood mixing effect, little splash etc..
5, the hydraulic loop system configuration: the fuel tank capacity: 80L, hydraulic pump flow: 10L/min, accumulator 6.3/31.5map,
The drive motor speed: 5.5kW, 1450/min, voltage 380V50Hz. Booster valve, safety valve, relief valve, pressure gauge.
6, A/B tank configuration: Volume: 250L, 304 stainless steel liner material,sandwich structure, the outer layer of cold plate welding. The stirring motor (1.1 kW, ratio 1:15), a regulator, air mixer, safety valve, pressure gauge. The set pressure limit of 0 ~ 3kg/cm2, the pressure coefficient 6kg/cm2. Tank installation of PT100 temperature sensor, the accuracy of + 0.5. Install tank outside the magnetic level gauge, convenient operation and visual material conditions. The upper and lower ends is provided with an electronic liquid level sensors, connected to the PLC, when the material storage than the set upper and lower limit can immediatelystart the automatic feeding system.
7, filtration system: adopting self cleaning filter.
8, automatic feeding system: A/B dope bucket raw materials to meet the line alarm,start the automatic feeding system easy to dope added to dope bucket. Labor saving.
9, electrical control system: color delta touch screen, PLC control system.Pressure, temperature, set the injection schedule, fault alarm, automatic operation or manual operation and parameters. And with the production time, productionoperation times record. Set the range of injection time is 0.5 ~ 99.99 seconds, set the range of work is 1 ~ 60 digits. In the general parameter setting screen function bar is arranged in the "previous" and "next page", "back" button, the "previous" and "next page" button are respectively used for page switching, the "back" button toreturn to the main menu.
