The stability and quality of the insulating glass is determined by the stability of the plastic machine.
Gear metering pump: Branch gear metering pump with involute tooth shape, the displacement correction, flow smoothly and uniformly, no pulsation. For the regulation of the flow can only adjust the pump speed, the flow of the pump is proportional to the speed of the regulation is simple.
Other types of pumps: (to the piston pump as an example) flow output is a unit, the flow fluctuations, easy to cause the rubber is not.
Because of the unique design to make the flow output no pulse, gear metering pump: application of gear metering pump. Eliminating the need for the hydraulic station and the valve and buffer components, so that the system is simplified, the interest is reduced and the performance is improved.
Two. The requirements and sealing method of the two groups of rubber compound
And a special cleaning tank, gear metering pump: simple structure. The pump itself to most of the impurities in the self - cleaning, the pump can also be a positive inversion, further to the impurities in the self - cleaning, the maximum level to avoid the impact of the particles on the pump.
One way valve is sensitive to the particle impurities, other types of pump: the piston pump with a one-way valve. The time is easy to be polluted, so the cleanliness of the sealant is very high. The use of PTFE sealing plunger pump, long time work, easy to wear glue seeping.
Three pairs of two groups of plastic machine structure
When the pressure of the AB group is not all, other types of pump: the use of other types of pump. Pressure regulating process, the hydraulic station will heat up.
I hope that more than two groups of plastic machine information for everyone to help.
