Abstract

The invention relates to an automatic layered sampling system for a tank truck. The automatic layered sampling system comprises a sampling surge flask, a peristaltic pump, a multilayer sampling distributor, a control system and a tank truck crane pipe sampling system, wherein a port in the side of the upper part of the sampling surge flask is connected with an outlet of the peristaltic pump; an inlet of the peristaltic pump is connected with the multilayer sampling distributor through a pipeline; an exhaust port is formed in the top of the multilayer sampling distributor; four distribution pipes connected with the tank truck crane pipe sampling system are arranged at the bottom of the multilayer sampling distributor. The automatic layered sampling system for the tank truck has the beneficial effects as follows: (1), the sampling precision is high; (2), all layers are automatically sampled once, and the operation is simple; (3), the sampling surge flask is made of a transparent material, so that direct observation is convenient.

Description

technical field [0001] The invention relates to the technical field of liquid automatic sampling equipment, in particular to a layered automatic sampling system for tank cars. Background technique [0002] At present, in the process of sampling oil liquids transported by tank trucks, the standards adopted in my country are GB / T 1999-2008 "Sampling Method for Coking Oil Products" and GB / T4756-1998 "Manual Sampling Method for Petroleum Liquid Products". , there are still some deficiencies, which are manifested in the following aspects: First, the sampling method is manual sampling. During the sampling process, the sampling personnel are exposed to the dangerous gas volatilized by the sampling material for a long time, which affects the health of the sampling personnel; Due to manual sampling, the sampling efficiency is low, and human subjective factors also have a certain impact on the representativeness of the sampling results, which affects the accuracy and representativeness ...
