Description
Technical field
The utility model belong to rail tank car unload oil technical field, be related to a kind of structure improved Unloading Arm.
Background technique
Currently, domestic rail tank car is unloaded, oil is all made of top and unloads oil process, i.e., is pumped by oil filling riser from tank truck top
Or the method emptying of siphon gravity flow.In high temperature season and plateau low pressure area, using such method, especially siphon gravity flow
Method often generates oil filling riser vapour lock, prevent the remaining oil liquid in tank truck is unloaded under.When not only extension is unloaded after vapour lock generates
Between, increase oil liquid volatilization consumption, cause when serious cutout and can not emptying, seriously affected the normal operation and railway of oil depot
Transport, and cause serious economic loss.
Oil filling riser vapour lock Producing reason is: the air containing dissolution in oil liquid, this under certain temperature and atmospheric action
Solubility also will increase.When the residual compression that certain in Unloading Arm is put is subatmospheric, the air being dissolved in oil liquid is precipitated,
Form bubble.Oil liquid can also carry air secretly during transportation simultaneously.Further, since the residual compression of oil liquid is lower than big in oil filling riser
Air pressure, oil liquid will continue to evaporate, especially when the residual compression of oil liquid in oil filling riser is lower than oil liquid saturated vapour pressure, this steaming
It was found that as that can be further exacerbated by.The oil-gas accumulation of the air carried secretly and evaporation is in oil filling riser in the air that is precipitated in this way, oil liquid
Highest point forms airbag, generates vapour lock, blocks emptying.
In addition, the temperature of tank truck internal oil is that upper layer is high, lower layer is low.Traditional vacuurn-centrifugal pump is that oil filling riser is inserted into oil tank
The bottom of vehicle, oil liquid are drawn off from the import of the lower end of oil filling riser through oil filling riser, and what is drawn off first is the oil liquid of tank truck lower part, finally
What is drawn off is the oil liquid on tank truck surface.This emptying process is unloaded temperature lower oil liquid when being clearly present high liquid level, and low
The higher oil liquid of temperature of unloading when liquid level causes to be lower than the vaporization pressure of oil liquid in the residual compression on oil liquid later period oil filling riser top of unloading
Power, therefore vapour lock is easily generated in high temperature season and plateau low pressure area, most oil liquid can not be unloaded.
