Embodiment

[0029] Embodiment: the bottom-sweeping method of railway oil tank car is:

[0030] An oil-gas separation tank 14 is set between the oil tanker and the oil storage tank;

[0031] Through the bottom sweeping oil pump 2 and the bottom sweeping hose 1, the oil in the lowest part of the tanker is delivered to the top oil inlet of the oil-gas separation tank 14;

[0032] When the oil liquid level inside the oil-gas separation tank 14 is higher than the upper limit position, the oil delivery pump 11 is started, and the oil product inside the oil-gas separation tank 14 is delivered to the oil storage tank from the oil outlet at the bottom thereof;

[0033] When the oil liquid level inside the oil-gas separation tank 14 is lower than the lower limit position, the oil delivery pump 11 is stopped;

[0034] When the pressure in the oil-gas separation tank 14 is greater than the set upper limit, the bottom sweeping oil pump 2 is stopped.

[0035] In this embodiment, the upper limit posit...

Abstract

The invention provides a rail tank car bottom sweeping method, belongs to the field of railway engineering reconditioning operation and aims at solving the problem that air existing in an oil discharging pipe in the existing rail tank car bottom sweeping process affects the oil discharging efficiency and accordingly potential safety hazards exist. An oil-gas separating tank is added in a middle link of a delivery pipeline between a tank car and an oil tank, and the bottom sweeping process is started or stopped according to the oil level in the oil-gas separating tank. The rail tank car bottomsweeping method comprises the specific steps that the oil-gas separating tank is arranged between the tank car and the oil tank; the oil at the lowest part of the tank car is delivered to a top oil inlet of the oil-gas separating tank through a bottom sweeping oil pump and a bottom sweeping hose; when the oil liquid in the oil-gas separating tank is higher than an upper limit position, an oil delivery pump is started, the oil in the oil-gas separating tank is delivered to the oil tank from a bottom oil outlet of the oil-gas separating tank; when the oil liquid in the oil-gas separating tank islower than a lower limit position, the oil delivery pump is stopped; when the pressure in the oil-gas separating tank is greater than a set upper limit value, the bottom sweeping oil pump is stopped.

Description

technical field [0001] The invention belongs to the field of railway locomotive maintenance operations, and relates to a bottom sweeping control process of an oil tank car in fuel unloading. Background technique [0002] There are mainly two kinds of piping systems for unloading oil tankers into oil storage tanks during railway locomotive maintenance operations. One of the piping systems is the oil unloading piping system; the other piping system is the bottom sweeping piping system. [0003] The operation process is that the oil tanker is parked facing the oil crane. After the oil crane is inserted into the oil tanker, the platform operator informs the pump room operator to start the oil pump and start unloading the oil; when the oil in the oil tanker is about to be sucked by the oil crane pipe, the stacker The operator on the platform informs the operator in the pump room to stop the unloading pump; the platform operator connects the bottom sweeping oil hose to the oil co...
