High-pressure mixing head: v-type three-time mixed filling head, selecting high-quality alloy steel using domestic heat treatment process with local hardness above HRC68, precision processing equipment precision machining, ensuring parts processing accuracy, clean appearance, can ensure that the use of more than 1 million times without failure. The two kinds of raw materials are mixed by high-pressure atomization injection (inclined plane mixing) to form a swirl in the mixing cavity, and 30% of the mixing effect is characterized by fast mixing speed and good mixing effect (discharge relaxation and no bubbles). The action of the discharge shaft and the cleaning shaft can be poured continuously and repeatedly, and the cleaning shaft automatically completes the cleaning action without wasting raw materials.

2. High and low pressure conversion valve: adopt high-pressure 35mpa stainless steel material, optimize valve body structure, pressure-resistant and wear-resistant seal to ensure no leakage for a long time, with its own limit stroke switch to ensure accurate and eye-catching action, rapid pressure conversion without pause, increase perfusion speed, freely switch high pressure in non-perfusion time to reduce system pressure, reduce system energy consumption, reduce equipment wear, prolong equipment service life.

3. Permanent magnet coupling: permanent magnet coupling is a new type of coupling which connects the power unit and the driven mechanism through the magnetic force of permanent magnets. It does not need direct mechanical connection, but makes use of the interaction between rare earth permanent magnets. The use of magnetic field can penetrate a certain space distance and the characteristics of material to transfer mechanical energy. The magnetic coupling is mainly composed of outer rotor, inner rotor and isolation sleeve, which completely solves the problem of seal leakage in the mechanical device and the frequent replacement of seals in the raw material pump. Man-machine interface: using large screen touch screen design, the operation is more intuitive, easy to understand, effectively reduce misoperation, a large number of automatic control technology is used to ensure the safe operation of equipment, and embedded fault diagnosis system, equipment data is intuitively reflected and there are corresponding sound and light prompts and automatically stop operation to effectively protect the safety of equipment and personnel.

4. High pressure plunger pump and Germany rexroth and China gelanrex, two well-known polyurethane special pump manufacturers to establish a long-term cooperative relationship for supporting supply. The high pressure plunger pump has the following characteristics: the repeatability of all kinds of flow measurement accuracy is high. First, the flow rate is manually adjusted by the handwheel with built-in accurate measurement scale, which is accurate and smooth. One working pressure can reach 25mpa-one inlet pressure is low, it can pump high viscosity liquid-through the use of special matching materials and special seals, the pump parts are compatible with the pumped materials (polyhydroxyl compounds, isocyanates). The flow pulsation is small and the volume efficiency is high.
