Abstract
The utility model relates to a jet vacuum pump taking water as the actuating medium. The utility model is characterized in that the jet ejector is equipped with the pore plate with a suction hole and a spray hole in it, and the top of the jet ejector is equipped with air suction pipe sealing connected to the suction hole of the pore plate and a tangentially incoming inlet channel paralleling to the pore plate. It has the advantages of professional design, high suction capacity, good use effect and energy saving. It can realize the final vacuum by preventing the air suction pipe from sucking water.
Description
It is the vacuum pump of working medium with water that the utility model relates to a kind of.
It is reported, existing jet vacuum pump, the sucking pipe of its sparger is positioned at the orifice plate bottom of sparger, intake pipe is positioned at the top of sparger, as designed " a kind of fluid jet vacuum pump " of Liaoning Province's fluid engineering design studies (CW86207978), it is crooked concentrated that the structural type of this side draught gas has the jet water column, and the partial water sealing is bad, the serious disadvantage that influences aspiration and easily cause sucking pipe to absorb water.
The purpose of this utility model provides a kind of reasonable in design, and aspiration is big, and using effect is good, and is energy-conservation, can prevent that the sucking pipe suction from realizing the jet vacuum pump of ultimate vacuum.
Technical solution of the present utility model is, will be by base, and the jet vacuum pump of formations such as motor, water pump, sparger, circulating tank, vacuum buffer tank improves.In order to solve the problem that sparger side draught gas easily causes the sucking pipe suction, orifice plate in the sparger is made the orifice plate that has suction port and spray-hole, and be provided with the sucking pipe and be the intake pipe that tangent line enter parallel that is tightly connected with the orifice plate suction port at the top of sparger with orifice plate, it is upward air-breathing that it is become, the structural type of last water inlet.
The utility model compared with the prior art, owing to made sparger air-breathing, the structural type of last water inlet, therefore, not only solved sparger side draught gas and easily caused the problem of sucking pipe suction, and had reasonable in design, aspiration is big, using effect is good, and is energy-conservation, can realize advantages such as ultimate vacuum.
Describe a specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of the sparger among Fig. 1.
Referring to Fig. 1, Fig. 2, on the rectangular base 1 that is welded into by channel-section steel, water pump 3 and the circulating tank 4 that links with motor 2 arranged by bolton.There is sparger 7 at place, water inlet on circulating tank 4 tops by the flange binding.Be welded with the supporting member of making by channel-section steel 9 at circulating tank 4 ends that sparger 7 is installed, and on supporting member 9, vacuum buffer tank 6 arranged by bolton.12 of the sucking pipes of the air outlet hole of vacuum buffer tank 6 and sparger 7, linking by flange has pneumatic tube 8.11 of the intake pipes of top side portion on the delivery outlet of water pump 3 and sparger 7, linking by flange has conduit pipe 5.The input hole of water pump 3 links by the outlet pipe 10 of flange and circulating tank 4.Orifice plate 13 in the sparger 7 is that a middle part has suction port 15, and perimembranous is furnished with the orifice plate of spray-hole 14.Be cast with the sucking pipe 12 that is tightly connected with orifice plate suction port 15 and be the intake pipe 11 that tangent line enter parallel with orifice plate 13 at the top of sparger 7.
