Foaming machine series

Low-pressure PU foaming machine unit (not applicable for explosive or flammable foaming agent such as pentane)

This machine is used for metering and mixing two different raw materials in required ratio. In order to reach the technical requirements, there equipped with a cooling device and a temperature control device. Besides, this machine can control pressure and metering of materials, and it can control injection, cleaning and blowing by computer, too.

Constituents and main technical parameters:

1. Tank assembly

Including four 220L tanks with a jacket, two layers of stainless steel wall, and pipe-type filters; mixing power: 0.55kw×4; mixing revolution: 60r/min.

2. Pump unit assembly

Two internally-engaged gear pumps, two infinitely speed controllers, power: 3kw

Revolution and pressure digitally displayed.

Throughput is between 70 to 200g/s when the mixing ratio is 1:1.

Two sets of pipes are equipped.

3. Mixing head assembly

One high-speed mixing head with the mixing revolution of 4500r/min and the mixing power of 1.5kw, revolution adjustable by frequency variation; two pneumatic ball valves; automatic-cleaning installation with a 25L detergent tank made of stainless steel; and elevant cleaning valves and solenoid valves.

4. System of materials

One water-chilling machine of 5HP; suitable hydraulic solenoid valves and pipes and other valves; material temperature digitally displayed and adjustable through a changeover switch; one water-heating tank of 6kw is included.

5. Auto material-supplementing installation

Two pneumatic diaphragm pumps with level control switches.

6. Main electric control

One control panel adopting a PLC controller except the electromotor, air cylinders, electric heating pipe and solenoid valve and other executive components; the following parameters can be preset: injection time (setting at user’s will), cleaning time, air-jetting time, alarming time and injection, cleaning and air-jetting actions.
