Deep water sampling and detection are often used in the environmental protection industry and the chemical industry. Among them, uncontrollable underwater environment, variable depth requirements and other objective reasons have caused difficulties in deep water sampling.
The traditional underwater sampling test uses vertical or plexiglass water collectors, and its working process is as follows:
① Equipped with a corresponding weight sinker-device sinking
②Sinking water flows continuously through the sampler
③ After the predetermined depth is reached, the container is closed
④Water sample collection is completed, the sample rises and gets back
(Leadfish and winches are necessary when necessary to meet different water depth requirements)
Disadvantages of water sampling:
Sampling volume is limited, when the demand is large, it must be done by repeated sinking and collection. When collecting water samples of different depths, the operation is complicated, the efficiency is low, and the precise water depth in the emergency environment cannot be guaranteed.
Typical applications of peristaltic pumps
include water treatment, and we are very familiar with the supporting applications in water quality testing. Similarly, peristaltic tube pumps
can also be used for deep water sampling, which is stable and easy to operate, greatly improving the efficiency of sampling work and ensuring testing Work safety of personnel.
Self-priming is a major advantage of the parasitic pump
. The self-priming peristaltic pump is used to replace the traditional water collector for deep water sampling. The water sample can be directly injected into the sampling bottle through the sampling tube. Deep water sampling has multiple advantages.
Simple system operation and convenient pumping
Sustainable pumping to meet large flow sampling
One job, adjustable to obtain multiple depth samples
The pipe diameter is small in cross-section, and is little affected by water flow
Can be used in rapid hydrological environment with stable work
Water collection system needs to be equipped with waterproof peristaltic pump
Head range, select the appropriate peristaltic pump model
Wash the pump tube and sampling bottle in advance to ensure the originality of the sample
The cable length of the down-draw winch controls the sampling depth
A coarse filter needs to be installed at the water inlet to avoid blockage of the nozzle
