Problems solved by technology

[0002] At present, there are many types of crane pipes used for unloading tanks in the petrochemical industry, but there are two general problems: one is that most oil unloading crane pipes are prone to air resistance and cavitation when unloading tanks in high temperature and low pressure areas. Not only does it take a long time to unload the tank, the loss of oil and gas is large, but there are also some safety hazards; secondly, in order to ensure the high efficiency of oil unloading, an independent vacuum sweeping system must be configured, otherwise it will be impossible to recover the stagnant bottom at the bottom of the tank. oil and affect oil recovery
However, it is still necessary to configure an independent stripping system, otherwise the bottom oil stuck at the bottom of the tanker still cannot be taken out

Embodiment Construction

[0015] As shown in the figure, a hydraulic unloading submersible pump crane tube unloading tank stripping system is an innovation based on the aforementioned ZL99234121.3 patent. This innovation is mainly based on the existing positive pressure unloading system. A negative pressure stripping device is added to the oil system. The unloading and stripping system of the crane pipe of the hydraulic unloading submersible pump is composed of a crane pipe assembly, a submersible pump system, an oil pressure station and a stripping system, and is characterized in that:

[0016] A. The oil pressure station is a hydraulic power output mechanism consisting of an explosion-proof motor, a duplex pump 3, two high-pressure oil pipes, and an oil return pipe located in the oil tank 1;

[0017] B, the described submersible pump system is composed of submersible pump 10, trousers-shaped fork pipe 14, gear motor 11, hydraulic station based on duplex pump 3, high-pressure oil pipe, and oil return ...

Abstract

An oil unloading and emptying system for the hydraulic dumping oil tank is composed of pitching tube module, submerged oil pump module, hydraulic station and tank-emptying system. Said hydraulic station has a hydraulic power output unit consisting of antiexplosion motor and duplex pump in oil tank. Said submerged oil pump module consists of submerged oil pump, fork pipe, plunger motor, said hydraulic station and pressure delivering pipeline. Sadi tank-emptying system comprises said duplex pump, emptying pump, fork pipe, three-way and valves.

Description

technical field [0001] The invention relates to a tank unloading and tank stripping system of a crane pipe of a hydraulic unloading tank submersible pump, which belongs to the category of fluid conveying devices, and is especially suitable for loading and unloading liquid materials in the petrochemical industry. Background technique [0002] At present, there are many types of crane pipes used for unloading tanks in the petrochemical industry, but there are two general problems: one is that most oil unloading crane pipes are prone to air resistance and cavitation when unloading tanks in high temperature and low pressure areas. Not only does it take a long time to unload the tank, the loss of oil and gas is large, but there are also some safety hazards; secondly, in order to ensure the high efficiency of oil unloading, an independent vacuum sweeping system must be configured, otherwise it will be impossible to recover the stagnant bottom at the bottom of the tank. oil and aff...
