The inlet and outlet flanges of the YG explosion-proof pipeline pump
are on the same center line, which can be directly installed on the
pipeline. The vertical structure, the machine and the pump are
integrated, the floor space is small, and the installation is very
convenient. This pipeline pump adopts high-quality mechanical seal
without leakage, which effectively reduces the oil and gas content of
the pump room, and improves the safety and reliability of the pump room
by taking care of the working environment. The suction pressure of the
oil pump is less than or equal to 1.0MPa, or the maximum working
pressure of the pump system is less than or equal to 1.6MPa, that is,
the pressure at the suction port of the pump + the pump head is less
than or equal to 1.6MPa, and the static pressure test pressure of the
pump is 2.5MPa. Please indicate the system working pressure when
ordering. When the working pressure of the pump system is greater than
1.6MPa, it should be specified separately when ordering, so that the
overcurrent part and the connecting part of the pump are made of cast
steel during manufacture.
Ambient temperature<40℃, relative humidity <95%.
YG type explosion-proof pipeline oil pump can work outdoors without building a pump room.
2. The vertical structure machine and pump are integrated, which occupies a small area and is easy to install.
3.
