Product Introduction

----------------------------------------------------------------------

The process characteristics of the heat carrier furnace are low pressure and high temperature, using organic heating element heating furnace, with a temperature of 300 ℃ and a corresponding saturated vapor pressure of only 0.018MPA.

In addition, the liquid phase transports thermal energy, and the heat carrier after heat exchange still returns to the furnace for continuous heating without waste heat discharge; Equipped with complete operation control and safety monitoring devices; Save electricity, water, and operating costs.

Heat carrier furnaces are widely used in various industrial fields due to their safety and energy efficiency.

Calculation method for selection of organic heat carrier heating furnace: 1. In special cases, calculation is required [1]: A. Calculate the heater power or freezing power KW=W × △ t × C × S/860 × T W=mold weight or cooling water KG △ t=temperature difference between the required temperature and the starting temperature. C=specific heat oil (0.5), steel (0.11), water (1), plastic (0.45~0.55) T=time to heat to the desired temperature (hours) B. To determine the size of the pump, it is necessary to understand the customer's required pump flow rate and pressure (head) P (pressure Kg/cm2)=0.1 × H (head M) × α (specific gravity of the heat transfer medium, water=1, oil=0.7-0.9) L (required flow rate of the medium L/min)=Q (required heat of the mold Kcal/H)/C (medium to hot water=1, oil=0.45) × △ t (temperature difference between the circulating medium entering and leaving the mold) × α × 60
2. Selection of freezer capacity A, Q (freezing capacity Kcal/H)=Q1+Q2 Q1 (heat brought into the mold Kcal/H)=W (weight of raw materials injected into the mold per hour KG) × C × (T1-T2) × S (safety factor 1.5~2) T1 Temperature of raw materials in the material tube; The temperature at which T2 finished products are taken out of the mold; The heat generated by Q2 hot runner is Kcal/H B. Quick calculation method (not applicable for hot runner) 1RT=7~8 OZ 1OZ=28.3g (including safety factor) 1RT=3024Kcal/H=12000 BTU/H=3.751KW 1KW=860 Kcal/H 1 Kcal=3.97 BTU
3. Cooling water tower selection=A+B A, injection molding machine cooling water tower RT=injection machine horsepower (HP) × 0.75KW × 860Kcal × 0.4 ÷ 3024 B, refrigeration machine cooling water tower RT=refrigeration ton (HP) × 1.25. The mold temperature machine is selected according to the mold temperature required for processing different plastics
