High pressure polyurethane foam犀利士
injection machine (closed loop control system) has 1 POLY barrel and 1 ISO barrel. The two metering units are driven by independent motors. The output of the pump is changed by changing the output of the metering pump. This machine is specially used for pouring polyurethane products.
High Pressure Mixing Head
The L type twice mixing head adopts high quality alloy and the most advanced heat treatment process in China.All cleaning can be finished by clean shafts without wasting materials.
Permanent Magnet Joint Shaft
The permanent magnet joint shaft consists of outer rotor,inner rotor and isolation set,which solves the leaking issues in seal and troubles of changing the material pump seal frequently thoroughly.
Supplied in set by two famous PU special pumps manufacturers,one is Germany Rexroth, the other is China Gelanrex, Lingxin has built long term cooperation with them.
Product Features of High Pressure PU Machine:
1. Adopting three layer storage tank, stainless steel liner, sandwich type heating, outer wrapped with insulation layer, temperature adjustable, safe and energy saving;
2. Adding material sample test system, which can be switched freely without affecting normal production, saves time and material;
3. Low speed high precision metering pump, accurate ratio, random error within ±0.5%;
4. Material flow rate and presure adjusted by converter motor with variable frequency regulation, high accuracy, simple and rapid ration adjusting;
5. High-performance mixed device, accurately synchronous materials output, even mixture. New leakproof structure, cold water cycle interface reserved to ensure no blockage during long downtime;
6. Adopting PLC and touch screen man-machine interface to control the injection, automatic cleaning and air flush, stable performance, high operability, automatically distinguish, diagnose and alarm abnormal situation, display abnormal factors.
