A high-pressure metering pump device for transporting viscous liquid

Abstract

The invention discloses a high-pressure measuring pump device for conveying viscous liquids. The high-pressure measuring pump device comprises a pump and a high-pressure power transmitting device. The high-pressure power transmitting device is provided with a separation bag chamber and a separation bag. The separation bag is located in the separation bag. An inlet end of the pump is connected with a vessel with power transmission liquids. An outlet end of the pump is connected with an inlet of the separation bag chamber. An outlet of the separation bag chamber is connected with a measuring device through a measuring valve. An inlet of the separation bag is connected with a viscous liquid supply device through a liquid storage inlet valve. An outlet of the separation bag is connected with a viscous liquid receiving device. By the separation bag, solvent such as water is separated from the viscous liquids, power is transmitted through the separation bag, and high-pressure transmission is achieved. By heating the separation bag chamber and the liquids outside the same, temperature rise viscosity of the viscous liquids is lowered, better liquid transmission effect is achieved, and influence of the viscous liquids on the pump is avoided.

AI Technical Summary

Problems solved by technology

[0003] When used to transport viscous liquids, due to the high viscosity of viscous liquids and often containing some solid particles, such small particles will affect the sealing performance of the check valve, making it difficult for conventional metering pumps to transport such viscous liquids ;The current high-pressure metering pump has a one-way valve that cannot be closed normally, resulting in the failure to transport viscous liquid normally

However, gear pumps, screw pumps, etc. cannot form sufficient high pressure, and the flow rate is not accurate enough.
