PRODUCT INTRODUCTION
1. PRODUCT PROFILE
Cryogenic pump is a special pump, which is designed to transport cryogenic liquid, such as
liquid nitrogen, liquid argon, liquid hydrocarbons and liquefied natural gas, etc. in the field of
petroleum, air separation equipment and chemical plant. Its application is conveying low
temperature liquid from low pressure place to high pressure place. With the development of
air separation technology, low temperature liquid is widely used and developed. The main
function in the air separation equipment is liquid circulation, or to extract liquid from the
storage tank and press the liquid into the carburetor, then convey to the user after
vaporization.
The medium cryogenic pump conveyed is only cryogenic liquid, so must maintain low
temperature in the process of pump liquid. If once the pump absorbs the more heat from the
around, the gas generated because of a lot of vaporization of cryogenic liquid will affect the
pump work. Thus cryogenic pump has its own special requirements in structure, material,
installation and operation of such areas to achieve requirements for cryogenic liquid pumped.
LFP80-50 model is a vertical, grade 2, direct coupling pump, which is directly mounted on a
drive motor. All of these components are housed in a pump tank, which bear pump suction
pressure. The motor of LFP80-50 model pump units does not require the use of seal,
because the motor is designed be submerged in the liquid pumped. The submerged motor is
a part of standard supply units, all components are fully assembled together. The maximum
pump capacity of LFP80-50 model is 30m3/h, which depends on the speed and frequency of
the drive motor. No sealing model centrifugal pump is particularly suitable for the device
which cannot tolerate product loss caused by the shaft seal leakage
.
LFP80-50 model pump should be driven by an frequency inverter. If the inverter
manufacturer's instruction is provided, from which you can obtain the operation manual for
motor.
NOTE!
Variable frequency motor must be equipped with frequency inverter. Please refer to
the inverter manufacturer's instruction for more specific information about the frequency
inverter.
NOTE!
The frequency inverter is set to a constant voltage / frequency ratio: 380V@100Hz.
WARNING!
Because the motor designed to be submerged lubrication by the liquid pumped,
the specialist of submerged pump itself do not apply for liquid oxygen condition.
