Abstract
The utility model relates to a single spiral rod pump, comprising a pump body, a primary shaft, a pump sleeve, a sealing device, a spiral rod, a flexible shaft, etc. The structure of the utility model is characterized in that the primary shaft is directly connected with the pump sleeve, and the primary shaft and the pump sleeve are synchronously rotated. Whereas the spiral rod engaged with the pump sleeve is consolidated through the flexible shaft or the other side steering mechanisms on the pump body or an output tube. Because the flexible shaft and the spiral rod do not follow the primary shaft to rotate, the damage of the component is avoided or relieved. The working quantity of the maintenance can be reduced, and the reliability of the work is improved. In particular the scheme is suitable for the single spiral rod pump with high pressure and high flow quantity, such as the water or the crude oil in a deep well.
Description
The utility model belongs to single screw rod displacement pump.
Existing various helical rotor pump primary shafts are general all to be connect with screw rod, and screw rod is meshed with pump block, but the pump block and the pump housing are fixed motionless.The compound motion of screw rod makes transmission jack shaft such as flexible shaft, cardan shaft and primary shaft produce additional live load and moment of flexure.Members such as the fragile universal joint of this adjection, flexible shaft, coupling and seal arrangement have increased the maintenance load of pump, have reduced functional reliability.This kind situation heals with the increase of design pressure, flow and becomes serious.
The purpose of this utility model is to eliminate the compound motion of screw rod, and the damage that prevents or alleviate member improves functional reliability.
Above-mentioned purpose is realized by following scheme: the direct and pump block connection with primary shaft, and do rotation synchronously.And the screw rod that will be meshed with pump block is consolidated on the pump housing or the output tube by jack shaft such as flexible shaft or other side steering, and like this, flexible shaft and screw rod are all with primary shaft and pump block rotation.Fluid output terminal at pump block is provided with the rotary machine seal arrangement.
The advantage of this programme is, because screw rod does not rotate, can thoroughly avoid jack shaft especially in the problem of screw rod and jack shaft joint easy-rupturing or damage, significantly reduces maintenance load.Make pump work more reliable, design pressure, the helical rotor pump that flow is bigger become possibility.Be specially adapted to aspirate water or crude oil in the deep-well.
Further specify this novel scheme with reference to accompanying drawing:
Accompanying drawing is this novel structural principle schematic representation.
Primary shaft 1 directly links with pump block 2 and rotates synchronously.Bearings 4 in the pump housing 3 are that the revolution to pump block 2 play supporting role.Install back rotatable mechanical seal device 5 at the pump block output terminal, to prevent the leakage of output medium.Screw rod 6 is fixed by the flexible shaft 7 and the pump housing 3.
Claims (3)
1, a kind of helical rotor pump, reaching the flexible shaft (7) that links with the pump housing by primary shaft (1), pump block (2), the pump housing (3), mechanical seal device (5), screw rod (6) forms, the utility model feature is pump block (2) rotation that is meshed with screw rod (6), and screw rod (6) is consolidated on the pump housing (3) or the output tube by jack shaft.
2, helical rotor pump according to claim 1 is characterized in that pump block (2) rotation is by the supporting of the bearing (4) in the pump housing (3).
3,, it is characterized in that rotary machine seal arrangement (5) being housed at the output terminal of pump block according to the described helical rotor pump of claim 1.
