Abstract
The present invention seeks to design a kind of submersible pump compound water inlet, to solve the easy etching problem of existing water inlet.Specifically, submersible pump compound water inlet, have the body that plastics are made, pipe end is fixed with metal flange, be enclosed within body outer end with the flange sleeve of body with material and pack in metal flange, outer surface of tube body and flange sleeve internal surface are welded as a whole simultaneously.The present invention adopts plastic tube body termination welded flange cover, and use metal flange load capacity, plastic tube is not perishable, and metal flange bearing capacity is large, and be convenient to fix submersible pump at well head, not only extend submersible pump water inlet working life, and solve metal erosion polluted water problem.<!--1-->
Description
Technical field
The invention belongs to conveying equipment for fluid substances technical field, particularly submersible pump fixture.
Background technique
Submersible pump generally uses more in down-hole, because outlet pipe end will be connected with aboveground conduit pipe (general flexible pipe is more), also to fixedly mount at well head simultaneously, so submersible pump water inlet generally adopts metallic conduit to be connected with metal flange, but metal tube due to groundwater corrosivity comparatively large, general service life 3-5 just corrosion need to change.
Summary of the invention
The present invention seeks to design a kind of submersible pump compound water inlet, to solve the easy etching problem of existing water inlet.
Specifically, submersible pump compound water inlet, have the body that plastics are made, pipe end is fixed with metal flange, be enclosed within body outer end with the flange sleeve of body with material and pack in metal flange, outer surface of tube body and flange sleeve internal surface are welded as a whole simultaneously.
The present invention adopts plastic tube body termination welded flange cover, and use metal flange load capacity, plastic tube is not perishable, and metal flange bearing capacity is large, and be convenient to fix submersible pump at well head, not only extend submersible pump water inlet working life, and solve metal erosion polluted water problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As figure gives submersible pump compound water inlet embodiment of the present invention.It has the body 1 that plastics are made, and it is characterized in that body 1 termination is fixed with metal flange 2, is enclosed within body 1 outer end with the flange sleeve 3 of body 1 with material and packs in metal flange 2, and body 1 outer surface and flange sleeve 3 internal surface are welded as a whole simultaneously.Body 1 upper tip extension cuts open into multiple discrete piece 4 be connected on body, and multiple discrete piece and flange sleeve 3 upper-end surface are welded as a whole.By such connection, not only body welds with flange sleeve facade, and end face is also welded as a whole, and adds the fixing of connection.
Claims (1)
