Abstract
The utility model relates to an axial division horizontal multi-stage conveying main pump which comprises a pump body, a pump cover, a pump shaft, a bearing part, a sealing part, impellers and a throttling sleeve, wherein the pump body, the pump cover and the overflow surface of each impeller are provided with synergistic wear-resistant coatings; a shaft head oil pump is arranged on a non-driving side; and a pump body seal, a sealing ring base, an intermediate sleeve and a suction sleeve which are axially arranged and distributed between the impellers are of a vertical split structure. The main pump has the advantages of simple structure, safety, reliability, obvious energy-saving effect, high use efficiency, convenience in equipment installation and maintenance, and suitability for long-distance delivery of crude oil.
Description
Technical field the utility model relates to a kind of centrifugal pump, and particularly a kind of axial subdivision horizontal multi-stage that is used for remote pipeline conveying crude oil is carried main pump.
Background technique is present; (generally being about about 3000KW), efficient require height, are suitable for production requirements such as wild environment operation and supplementary equipment configuration relative complex, the domestic also not design of this series products and manufacturing greatly owing to remote pipeline carries main pump to have output power.
The purpose of summary of the invention the utility model is to provide a kind of high efficient and reliable, convenient, the remote axial subdivision horizontal multi-stage of carrying of maintenance to carry main pump.
For achieving the above object, the utility model axial subdivision horizontal multi-stage carries main pump to comprise the pump housing, pump cover, pump shaft, bearing part, sealed member, impeller, orifice sleeve, and its middle pump body, pump cover and impeller wetted surfaces are coated with the synergy wear-resisting coating; Set up the spindle nose oil pump at non-drive side; The pump housing sealing, seal ring seat, middle cover, the suction that are provided with vertically and are distributed between impeller are overlapped for dividing body structure up and down.
After adopting said structure, because impeller and pump housing runner wetted surfaces all scribble the synergy wear-resisting coating, its surface finishment is than other metals and general composite material, and surface friction drag reduces greatly, and pipeline carries main pump efficient to improve obviously.Set up the spindle nose oil pump at non-drive side, because of the unsuitable open-air outside fuel feeding design of using of cancellation, greatly reduce the possibility that equipment meets with thunderbolt, the equipment operation reliability improves greatly.Pump housing sealing, seal ring seat, middle cover, suction cover adopt and divide body structure up and down, and after the rotor part installation, the equipment of being convenient to is installed and maintenance.
The characteristics of the utility model are: simple in structure, safe and reliable, energy-saving effect is remarkable, and utilization efficiency is high, and maintaining equipments is convenient, is applicable to that crude oil carries at a distance.
Description of drawings Fig. 1 is that the utility model axial subdivision horizontal multi-stage is carried main pump overall structure schematic representation.
Fig. 2 covers synergy wear-resisting coating schematic representation for showing like Fig. 1.
Fig. 3 is for showing the secondary split structural representation of friction of rest like Fig. 1.
Embodiment is described further the utility model below in conjunction with accompanying drawing:
As shown in Figure 1; The utility model axial subdivision horizontal multi-stage carries main pump to comprise the pump housing 14, pump cover 5, pump shaft 3, bearing part 2,15, sealed member 4, impeller 10, orifice sleeve 6; Cover synergy wear-resisting coating (showing) after its middle pump body 14, pump cover 5 and polishing of impeller wetted surfaces process and the sand blast like Fig. 2; This coating can effectively improve pump efficiency, reduces power of motor, and energy-saving effect is remarkable.Increase spindle nose oil pump 1 at the pump non-drive side, the top petrol tank design of cancellation lubrication system reduces equipment greatly and meets with the possibility that thunderbolt waits complicated meteorology to destroy in the open air.The pump housing sealing 7,12,13, seal ring seat 8, middle cover 9, the suction that are provided with vertically and are distributed between impeller overlap 11 for dividing body structure (showing like Fig. 3) up and down; Rotor need only once be pre-installed and get final product; Need not dismantle and install rotor by secondary after the dynamic balancing, equipment is installed and is safeguarded very convenient.
