Anti explosive filling machine sealing ring
Leakage of precision parts of the anti explosive filling machine not only affects the working efficiency of the system, but also may slow down the service life of theanti explosive filling machine, so a large number of sealing components will be used in the anti explosive filling machine. The function of sealing element is to prevent liquid or gas from flowing out of the gap between two matching parts, but also prevent external impurities such as air, dust, water and foreign matter and other intrusion of the device. Sealing elements are made of sealing materials, such as commonly used rubber rings.
Sealing apron material is different, the corresponding resistance is different:
Butadiene rubber, oil resistant, but not acid resistant, synthetic rubber;
Chloroprene rubber, oil resistance, wear resistance, acid resistance, acetylene base;
Isobutyl rubber, acid resistance, resistance to hydraulic oil;
Teflon can withstand high temperature, suitable for various media, and its characteristic expansion is small;
And ptfe is good lubricity, corrosion resistance, friction resistance, and toughness.
MG Packaging Machinery Co., Ltd. will consider the following requirements when designing and selecting anti explosive filling machine sealing rings:
Anti explosive filling machine should have good sealing performance, and with the increase of pressure and temperature change can automatically improve the sealing performance;
The friction between the sealing ring and the moving parts should be small, and the friction coefficient should be stable;
The anti explosive filling machine sealing ring has strong corrosion resistance, not easy to aging, long working life, good wear resistance, and can be automatically compensated to a certain extent after wear.
Simple structure, easy to use and maintenance, can make the sealing ring has a longer life.
The gear pump anti explosive filling machine
Anti explosive filling machine gear pump is a rotary pump that relies on the working volume change and movement formed between the pump cylinder and the meshing gear to transport liquid or pressurize it. The gear pump anti explosive filling machine consists of two closed Spaces: two gears, pump body and front and back cover. When the gear rotates, the volume of the space of the gear off side increases from small to large, forming a vacuum, and the liquid is sucked in. The volume of the space of the gear meshing side decreases from large to small, and the liquid is squeezed into the pipeline. The suction cavity and the discharge cavity are separated by the meshing lines of two gears. The pressure of the discharge outlet of the gear pump depends entirely on the size of the resistance at the pump outlet.
The anti explosive filling machine gear pump is driven by an independent motor, which can effectively block pressure pulsation and flow fluctuation in the upstream. The pressure pulsation at the outlet of the gear pump can be controlled within 1%. Using a gear pump in the extrusion line can increase the flow output speed and reduce the shearing and residence time of materials in the extruder.
When the anti explosive filling machine gear pump works, the driving wheel rotates with the motor and drives the driven wheel to rotate with it. When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber increases and the pressure decreases, and the liquid in the suction tube is sucked into the pump. The suction liquid is pushed by the gear in two ways in the tooth groove to the discharge chamber. After the liquid enters the discharge chamber, the teeth of the two gears are constantly meshing, so that the liquid is squeezed from the discharge chamber into the discharge pipe. The driving and driven gears rotate continuously, and the pump draws in and out fluid continuously.
The MG anti explosive filling machine gear pump is also equipped with a safety valve, when the discharge pressure exceeds the specified pressure, the conveying liquid can automatically push the safety valve open, high pressure liquid back to the suction pipe. So as to achieve no drip leakage.
