Problems solved by technology

The traditional ultra-high pressure oil pump generally adopts a horizontal structure, and the pressure value must reach the ultra-high pressure level. The volume of the body needs to be very large. If the size is too large, it is not conducive to use in production.
In the traditional oil pump, in order to achieve ultra-high pressure, there is a big problem with the sealing of the oil pump. If the pressure increases slightly, leakage will occur, which cannot meet the needs of production and use.
Traditional oil pumps include gear pumps, crankshaft horizontal reciprocating pumps, vertical swash plate pumps, centrifugal piston pumps, etc. The liquid medium conveyed by the pumps is water, and the other is oil. Generally, it cannot be used concurrently, and its scope of use is small, so it is not suitable for popularization and application.
The pressure value of the traditional oil pump is constant, and the flow rate is also constant. If you need a model of pressure value, you need to choose an oil pump. When you need to use multiple pressures at the same time, you cannot use the same oil pump.

Embodiment 2

[0036] Embodiment 2, the vertical double-acting spinning pump of the present invention, a thrust bearing 10 is arranged between the upper end of the screw shaft 6 and the pump body 11, so that the screw shaft 6 rotates relative to the pump body 11, and the screw shaft The upper end of 6 is connected with gear pair. At the same time, the gear pair includes a pinion gear connected to the motor input shaft 2, both pinions are matched with the middle and upper gears, and the middle and lower gears coaxial with the middle and upper gears are equipped with two helical shaft gears, and the helical shaft gears pass through the gear The box output shaft 5 is fixedly connected with the screw shaft 6 .

[0037] The screw sleeve 7 in the pump body, the function of the screw sleeve 6 is not only to transmit power but also to be the plunger part of the pump. The up and down movement of the plunger is driven by the screw shaft 6, but at the same time, it is in the pump cylinder 9. The liqui...

Embodiment 3

[0039] Embodiment 3, the vertical double-acting spinning pump of the present invention, the sealing group 8 includes an O-shaped sealing ring 8-1, an L-shaped sealing ring 8-2 and a tongue-shaped sealing ring 8-3, and the tongue-shaped The sealing ring 8-3 is located at the bottom of the spiral sleeve 7, and the edge of the tongue-shaped sealing ring 8-3 is attached to the inner wall of the pump barrel 9, and the L-shaped sealing ring 8-2 is located on the tongue-shaped seal outside the spiral sleeve 7. Above the ring 8-3, the O-shaped sealing ring 8-1 is located above the L-shaped sealing ring 8-2 outside the spiral sleeve 7. The sealing group is equipped with three layers of sealing defense lines, namely low pressure, high pressure and ultra-high pressure. Under what pressure, the seal will bear, thus greatly increasing the life of the seal and the operating rate of the pump.

Embodiment 4

[0040] Embodiment 4, the vertical double-acting spinning pump of the present invention, the detection control system includes a speed detection device and a control system, the speed detection device is located on the gear box 4, detects the speed of the gear pair and transmits the signal to A control system, the control system is connected to and controls the motor 1 . Through the speed detection device installed on the gear box, the speed of the gears in the gear pair is detected, and then the detection signal is transmitted to the control system. The control system is used to control the forward or reverse rotation of the motor according to the preset program. In this way, the opposite action between the two pump bodies can be controlled. When the medium in one pump body is compressed to form an ultra-high pressure medium, the other pump body will suck the medium into the pump body. The medium can be water or oil. When the medium in the two pump bodies When the action is ab...

Description

[0001] This patent application is a divisional application of the invention patent application whose application number is 2011104375544; the title of the invention is: a vertical double-acting spinning pump; and the application date is November 23, 2011. technical field [0002] The invention relates to a spinning pump, in particular to an ultra-high pressure spinning pump. Background technique [0003] At present, it is not easy for the conventionally used ultra-high pressure oil pump to reach a pressure of 250 MPa, because the oil pump needs to increase the pressure to this pressure value, which is limited by various conditions such as driving mode, sealing performance, and pressure bearing capacity. Oil pumps have always been a major problem to be solved for those skilled in the art. The traditional ultra-high pressure oil pump generally adopts a horizontal structure, and the pressure value must reach the ultra-high pressure level. The volume of the body needs to be very...
