Embodiment 1

[0045] Embodiment 1: A water sample collection system for sampling water from a pump pipe.

[0046] Such as figure 1 As shown, the sampling end of the nozzle plug-in sampling device 1 is arranged in the pump tube outlet of the water pump to be sampled, the nozzle plug-in connection with the output port of the sampling device 1 is connected to the input port of the self-priming pump 2 through a hose, and the self-priming pump The output port of 2 is connected to the tee 5 through the pipeline, and the upper port of the tee 5 is connected to two expansion tube filters 7 connected in series through the pipeline, and the upper port of the expansion tube filter 7 on the upper part is connected to the quality stabilizer through the pipeline 3, the bypass port of the tee 5 is connected to the diversion control valve 4, and the upper output port of the mass stabilizer 3 is connected to the split combined sampling bottle 6 through a pipeline.

[0047] The expansion tube filter 7 is an...

Embodiment 2

[0061] The water sample collection method for sampling from pump pipe drainage includes the following steps:

[0062] 1. The construction of the water sample collection system: first use a glass bottle to take a small amount of water from the outlet of the pump tube of the water pump to be sampled, and observe the water quality of the water. Tee 5, diversion control valve 4 and mass stabilizer 3 are assembled and connected to form the main body of the water sample collection system; , the mass stabilizer 3 and the two expansion tube filters 7 are assembled and connected to form the main body of the water sample collection system. The mass stabilizer 3 should be adjusted to be vertically arranged above the output port of the self-priming pump 2, and the expansion tube filter 7 is connected below the mass stabilizer 3 and is on a vertical line with the mass stabilizer 3.

[0063] 2. After the nozzle plug-in sampling device is assembled, the outlet pipe 24 is connected to the in...

Abstract

The invention relates to a water sample collection system and a water sample collection method for taking a sample from water drained from a pump pipe. The water sample collection system is formed as follows: the sampling end of a pipe orifice plugged sampling device is arranged in a water drainage pipe orifice of a quasi-water sampling pump pipe; the output port of the pipe orifice plugged sampling device is connected to the input port of a self-priming pump through a hose; the output port of the self-priming pump is connected with a three-way joint through a pipeline; an upper opening of the three-way joint is connected with the input port of a mass stabilizer through a pipeline; a bypass opening of the three-way joint is connected with a flow division control valve through a pipeline; the output port in the upper end of the mass stabilizer is connected with a split combined type sampling bottle through a pipeline. The water sample collection system disclosed by the invention can realize fast mounting and center positioning of a water outlet pump pipe of a water pump, so that the quickness and the convenience of sampling operation are improved; the water sample and environment-sensitive substances in the water sample pass through the collection system under a state of relatively dynamic balance, so that the disturbance is low, the escape quantity of volatile substances is small, and the fidelity of the sample is improved.

Description

technical field [0001] The invention relates to a water sample collection device and a collection method for collecting water samples containing volatile substances and oxygen-sensitive substances, in particular to a water sample collection system and a water sample collection method for sampling from pump pipe drainage. Background technique [0002] In the process of analyzing and researching the water quality containing volatile substances and oxygen-sensitive substances discharged from the pump pipe, the original water sample collection system uses the nozzle plugging or insertion sampling method for sampling operation. The operation steps of this kind of plug-in or plug-in connection are cumbersome, and the plug-in connection method can only extend the water inlet pipe of the water sample collection system into the pump pipe along the inner wall of the water pump outlet pipe, but it cannot guarantee that the water inlet pipe is located in the pump pipe. The position of t...
