Technical specification for a.PHR40F continuous high pressure foaming machine system
PHR40F continuous high pressure foaming machine is in the digestion and absorption on the basis of the technology of famous foreign companies for product development the equipment of advanced technology, reasonable structure, complete functions, high degree of automation, accurate measurement, convenient operation, beautiful durable, with open architecture, easy maintenance, stable performance, filling high repeat precision.

1 feeding system:
Tank unit consists of two sets, a set for poly tank storage, design for double layer structural carbon steel tank, the maximum working pressure 0.8MPa, equipped with a stirring system, a leak proof seal, complete reducer power 0.37 kW, the ratio of 40:1; tank wall insulation materials used in the insulation and liquid transfusion port using stainless steel hand valve control, the top of the tank is provided with a safety valve, exhaust valve and an air valve, for controlling the material tank pressure; another set for storage of ISO, equipped with heating device. The feeding driven by the motor maintenance free internal gear pump feeding, automatic by manual or single, effective volume of 200L tank.
2 Poly (polyether polyol) and ISO (isocyanate) high pressure metering unit:
High pressure metering pump selection of A2VK series high pressure axial piston pump. The series of metering pumps, to be precise, smooth operation, simple maintenance; two motor driving two metering pumps, by manually adjusting the metering pump variable first change the metering pump swing angle, to control the metering pump to spit out the quantity, motor and pump is connected with the magnetic sealing shaft connector, ensure metering pump run seal never leakage; and is equipped with high and low voltage digital display meter, pressure transmitter, used to control the pressure, when the pressure exceeds 6 - 20MPa, lower than the group pre Shi set pressure is 0.1MPa, the system will shut down automatically, alarm and display the corresponding fault information.
3 high pressure mixing head: BLQT type mixing head using high pressure impact mixing principle, mainly used for continuous foam production, mixing head out of the mouth with a cleaning device, used to stop the equipment when cleaning, prevent pipe blockage. The mixing head is arranged on the moving trolley of the mixed head of the production line.
4 material temperature control unit:
The temperature control unit is mainly used to control the material temperature of the two kinds of raw materials.
1 cold water machine, used for raw material refrigeration 25000cal / h
2 heating pipes are installed in each group, and the heating power is 3KW / root.
5 ratio test system: measurement of gun head
6 streamline filter
Used for filtering components, regular rotation of the filter wheel or handle, through the bottom of the ball valve.
7 flow control unit
Flow rate and flow rate of two (Germany) are used to display the flow rate of the 2 components in the pipeline.
8 electrical control system:
High tech electronic control, the system of each part of the process of coordination, control power supply transformer isolated power supply and switching power supply;
Programmable controller using a series of PLC, peripheral equipment using domestic CHINT or Germany Schneider products, independent development of high pressure foaming machine control programming input, to achieve manual and automatic control of the two operation.
II on the interface of man-machine conversation by 6.7 inches color operation device, make the measurement, the hydraulic tank stirring, mixing injection head etc. part according to the procedure coordination, used for setting, display the function of high pressure circulating time, injection time, the proportion of time.
9 stainless steel heat exchanger
Two stainless steel heat exchangers are respectively arranged on the two groups of the outlet, and the heat exchanger is connected with the other devices (heating / cooling) of the machine temperature control system to realize the section of the material temperature.
10 pipe unit
From the rack to the mixing head of the hard pipe and hose, pipe layout and length according to the user site plan to determine the length of all the material used in the pipe only.
11 main engine bracket
In order to transport and maintenance, the main engine bracket is designed into a platform structure, which is used for supporting the metering unit, the control unit and the electric appliance cabinet.
