Pumping unit, the requirement being able to bear strong corrosion could be met.But the pumping unit prepared using special corrosion-resistant metal materials, often cost
It is very high, it is difficult to bear in general chemical enterprise.By the continuous public relations of scientific worker, one is developed finally
The cost-effective method of kind, it is that non-metallic inner liner layer is set inside the flow passage components of conveying strong corrosive media pumping unit,
In order to meet the intensity requirement during pumping unit use, the mode that the liner of presently used pumping unit is nonmetallic includes adopting
With the common metal pump housing, non-metallic inner liner layer, non-metallic inner liner layer is arranged on the inwall of metal shell.But this liner
Processing mode, although reducing the manufacturing cost of pumping unit, when there is also it is more serious the drawbacks of, such as the processing in pumping unit
In manufacturing process, non-metallic inner liner layer can be caused to damage due to various.But do not have on this non-metallic inner liner layer
There is any method that can fast and effectively detect inner liner damage, this has resulted in staff and has been installed to chemical industry in pumping unit
When being run in process system, the damage of non-metallic inner liner layer can not be quickly found, can not on-call maintenance and replacement
Non-metallic inner liner layer, ultimately result in strong corrosive medium and directly contacted with common metal shell, cause outside the nonmetallic metal of liner
Shell is corroded, and so as to cause the danger of chemical process system, very big safety in production hidden danger be present.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide the detection side that non-metallic layer is served as a contrast in a kind of metal pump body
Method, this method can fast and effectively detect lining non-metallic layer in metal pump body and whether there is defect, simple to operate, and can have
The use cost of the reduction chemical industry user of effect.
The invention provides following technical scheme:
The detection method of lining non-metallic layer in a kind of metal pump body, including,
Initial survey, the initial survey are to inject conducting medium in the metal pump body with liner non-metallic layer, use inner liner
Lining non-metallic layer whether there is leak source in defect detecting device detection metal pump body.
Preferably, whole inspection is carried out in the case where the initial survey detects the presence of leak source, the inspection eventually is to use inner liner
The position of lining non-metallic layer leak source, size and number in defect detecting device detection metal pump body.
Preferably, electric signal occurrence of equipment, signal detection receiving device are integrated with the inner liner defect detecting device
And detection brush, detection brush, signal detection receiving device and the electric signal occurrence of equipment pass sequentially through wired in series company
Connect, the electric signal occurrence of equipment is also connected by wire with metal pump body case, when carrying out initial survey work, starts electric signal
Occurrence of equipment, the detection brush is placed in conducting medium, if signal detection receiving device have received electric signal,
Illustrate that detect brush forms closed-loop path with signal detection receiving device, electric signal occurrence of equipment, non-metallic inner liner layer is present
Leak source.
Preferably, when carrying out inspection work eventually, conducting medium is removed totally first, starts electric signal occurrence of equipment, makes
With detection brush scanning liner non-metallic layer, when signal detection receiving device have received electric signal, then illustrate exist at this
Leak source, so that it is determined that the position of leak source and size, are completely scanned using detection brush to liner non-metallic layer, so as to really
Determine the quantity of leak source.
Preferably, the liner non-metallic layer is fluoroplastic layer.
The beneficial effects of the invention are as follows:
1st, examined by the end of the initial survey to the metal pump housing and liner non-metallic layer, be capable of the quality of quick detection lining,
Improve final product quality and production efficiency.
2nd, the inner liner defects detection integrated by electric signal occurrence of equipment, signal detection receiving device and detection brush fills
Put, simple to operate, quick and precisely, and cost is low, facilitates staff quickly to screen the pump of existing defects for Detection results
Body.
Brief description of the drawings
Fig. 1 is the state diagram of the progress leak source detection of lining non-metallic layer in metal pump body.
The implication marked in accompanying drawing is as follows:
1- metal pump housing 2- liner non-metallic layer 3- electric signal occurrence of equipment 4- signal detection receiving devices 5- is detected
