Abstract
The utility model relates to a web wheel screw pump, which is formed by an arc-shaped spiral and a web wheel provided with teeth. The arc-shaped spiral is engaged with the web wheel. The arc-shaped face spiral adopts the diameter changeable structure. A pump casing is inlaid with an arc-shaped face sealing ring. The arc-shaped face sealing ring and the root disc are respectively anastomosed with the arc-shaped face of the arc-shaped face spiral. The function of a tooth plate is used for preventing the crude petroleum from motion in the circular mode with the spiral and moving the axial direction. A space whose volume can be changed are formed between the arc-shaped face sealing ring (7), the arc-shaped face spiral (2) and the root disc (6) of the web wheel. The utility model is driven by a liquid motor to work continuously. The utility model has the great advantage that the viscosity of the crude petroleum is higher, the transmitting pressure is larger and the distance of pumping is farther.
Description
The utility model relates to a kind of web wheel volute pump, is used to reclaim the crude oil that leak into river, river, Hu Hai, oil well side.Be specially adapted to the pumping of high viscosity oil.
The crude oil that China produces is higher because of containing cured amount, and mostly viscosity is bigger, and viscosity can reach more than the 1000cst during low temperature, and its physical state can be chocolate shape, bulk, pitch shape.
Known several oil pumps mainly are that vacuum pump is a two diaphragm pump etc. at present, be that the suction that utilizes negative pressure to produce comes pumping crude oil, be subjected to the restriction of barrier film amplitude in the working procedure, the suction that negative pressure produces is limited, block crude oil is very easy to blocking pipeline or can't pass barrier film, therefore use two diaphragm pump pumping crude oil only at the 5-9 in every year between the month, could proper functioning when viscosity of crude was low when temperature was higher.Also has a kind of pump volute pump, what adopt is equal diameter screw piece structure, can be used for pumps water or granular material, but pumping crude oil is not all right, because crude oil has certain viscosity, with the rotation of screw axis, stick at crude oil on the screw piece and only can be garden Zhou Yundong and can not move axially, do not reach the purpose of pumping crude oil.
The purpose of this utility model is to adopt the principle of helical feed material that a kind of web wheel volute pump is provided, crude oil that can the various viscosity of pumping, be specially adapted to the pumping of high viscosity oil, its maximum characteristics are that the pressure of the high more transmission of viscosity of crude is big more, and the distance of pumping is far away more.
The purpose of this utility model is achieved in that the cambered surface helical design become reducing, and Hand of spiral is left hand screw, and the root radius of axially seeing screw piece is R, and top radius is r, screw piece and rotatingshaft key joint.In the enclosure portion to stud with the radius made by engineering plastics of circle be the cambered surface seal ring of r, match for the r cambered surface with the helical blade top, designed a web wheel that radius is R in the bottom of cambered surface spiral, plate tooth and cambered surface screw piece on the web wheel match, when screw axis rotated, the moving web wheel of blade swinging plate cingulum rotated, and is similar to the type of belt drive of worm and gear, the effect of web wheel upper plate tooth is exactly to stop the crude oil that sticks on the blade to make garden Zhou Yundong, and forces it by moving axially.Like this, formed the space of a variable volume between the root garden of cambered surface seal ring, cambered surface screw piece, web wheel, the increase that utilizes difference in volume to obtain pressure reaches the purpose of continuous pumping crude oil.
Adopt this scheme can realize the pumping of high viscosity oil, and be not subjected to the restriction of environment, weather.Below in conjunction with drawings and Examples the utility model is described further.Fig. 1 is the schematic representation of web wheel volute pump.Fig. 2 is a cambered surface spiral sectional structure chart.
Among Fig. 1,1, web wheel volute pump shell; 2, cambered surface spiral; 3, spiral shaft; 4, web wheel; 5, plate tooth; 6, garden dish; 7, cambered surface seal ring; 8, oil hydraulic motor.
Consider the working environment of this pump, selecting for use of material must oil resistant, anticorrosion, antirust.Shell (1) adopts the rustproof aluminum alloy foundry goods, and cambered surface spiral (2), transmission shaft (3) are stainless steel material, and web wheel (4), cambered surface seal ring (7) are engineering plastics.
Among Fig. 1, cambered surface spiral (2) adopts key connecting with transmission shaft (3), and the two ends of transmission shaft (3) are furnished with bearing and rubber seal.Cambered surface seal ring (7), matches with the cambered surface at cambered surface spiral (2) screw piece top in pump case (1) with Bolt Connection, and its cambered surface radius is r.Because cambered surface seal ring (7) adopts engineering plastics, thus have good self lubricity and surface friction drag little.It is to be convenient to assembling that each plate tooth (5) of web wheel (3) adopts the bolt connection structure purpose with garden dish (6).The thickness of plate tooth is that 4mm and cambered surface spiral (2) match, and the radius of root garden dish is that r and cambered surface screw top cambered surface match.When driving transmission shaft (3), oil hydraulic motor (8) drives cambered surface spiral (2) rotation, effect crude oil by screw piece is advanced in the work B district of intermediate portion by suction port A district, the top of B district cambered surface spiral has the garden dish (6) of cambered surface seal ring (7) web wheel (3) to cooperate with it, it is enough little that gap between them can reach, and guaranteed not produce the pressure loss in the crude oil pumping process.In addition, web wheel (3) is in rotation process, and plate tooth (5) can stop the crude oil that sticks on the screw piece to make garden Zhou Yundong effectively, and pair moves axially it, makes to discharge the C district enough working pressures are arranged.Crude oil constantly sucks from the A district like this, arrives discharge C district by B district, along with the pressure in the C district crude oil that constantly raises can constantly be pumped into appointed positions.
Claims (3)
1, a kind of is the main web wheel volute pump that is used for pumping crude oil that constitutes by cambered surface spiral, web wheel, it is characterized in that: the spiral of band cambered surface uses key joint on transmission shaft, be meshed with a web wheel, the top cambered surface of spiral is coiled with the garden of cambered surface seal ring, web wheel respectively and is matched.
2, by the described web wheel volute pump of claim 1, it is characterized in that: the cambered surface seal ring, and matches with the top cambered surface of cambered surface spiral in shell with bolted on connection.
3, by the described web wheel volute pump of claim 1, it is characterized in that: it is that the root garden arc radius of R and cambered surface spiral is that R matches that each plate tooth and garden dish are used Bolt Connection, the tooth garden arc radius of web wheel.
