Abstract
The utility model relates to a pump which is composed of a motor, a pump body, a gear box body, etc. By a low speed rotor component and a high speed rotor component which are arranged in the gear box body, the low rotation speed of the motor is converted into the high rotation speed of a pump shaft. Thereby, a blade wheel is driven to rotate in high speed, and a strong pressure difference is generated to improve the delivery lift of the high-speed pump. The utility model which has the advantages of simple structure and convenient installation and operation can be used in different operating conditions and meet the requirements of different occasions.
Description
Technical field: the utility model relates to a kind of high speed pump, and particularly relating to a kind of being widely used in needs small flow, high-lift high speed pump in the industries such as oil, chemical industry, electric power, metallurgy, papermaking.
Technical background: at oil, industries such as chemical industry, extensively need a kind of flow little, the lift height, can be fit to the pump that more abominable working condition uses down, at present, for reaching the purpose of high-lift conveying, the general high speed pump that all adopts multistage pump to combine, though such pump can reach designed high-lift requirement, but owing to adopt multistage combination, cost is accordingly than higher, and during such pump operation, volume and mechanical loss are bigger, combination property is not high, and the flow lift curve falls suddenly, and variation in pressure is bigger during changes in flow rate, not too be suitable for the flow process supercharging, the only suitable medium of carrying clear water or being similar to clear water, because of the long easily vaporization of medium waiting time in runner, and floor space is big when carrying the light hydrocarbon medium, pump is heavier, installs pretty troublesome.
Summary of the invention: in order to overcome above defective, the purpose of this utility model is exactly that a kind of novel high speed pump will be provided.The purpose of this utility model is to realize like this, high speed pump is by the pump housing, motor, gear housing, formed towards sap cavity, high speed machine envelope institute, it is characterized in that: in described gear housing, be respectively arranged with high speed rotor parts and low speed rotor part, be meshing with each other by gear between two rotor parts; Described low speed rotor part below also is provided with the oil removal cover; Top at gear housing is provided with bleed screw.The utility model is simple in structure, axial dimension is little, the axle strength rigid is good, adopts the raising rotating speed to raise the efficiency, and has the unsteady flow stabilizing voltage characteristic, the flow lift curve is smooth, be most appropriate to the flow process supercharging, suit to carry various media, especially light hydrocarbon and contain solid particle class medium, and floor space is little, in light weight, advantage such as the highi degree of accuracy fine module gear has guaranteed unit running balance, vibration is little, noise is low is installed, easy to operate.
Description of drawings: Fig. 1 is a structural representation of the present utility model
In Fig. 1,1, motor 2, gear housing 3, high speed rotor parts 4, bleed screw 5, gear box cover 6, the pump housing 7, sealed case 8, high speed machine envelope 9, towards sap cavity 10, restrictor ring assembly parts 11, low speed rotor part 12, oil removal cover
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing 1.
High speed pump is characterized in that by the pump housing 6, motor 1, gear housing 2, formed towards parts such as sap cavity 9, high speed machine envelopes 8: be respectively arranged with in described gear housing 2 and be meshing with each other by gear between high speed rotor parts 3 and low speed rotor part 11, two rotor parts; Below described low speed rotor part 11, also be provided with oil removal cover 12; Be provided with bleed screw 4 on the top of gear housing 2.During concrete enforcement, low speed rotor part 11 rotations in the motor 1 driven gear casing 2, and rotating speed of motor is generally 2900r/min.Reach the high-lift rotating speed that needs to improve pump shaft.The utility model adopts the highi degree of accuracy fine module gear exactly, and just high speed rotor parts 3 pass through gear meshing with low speed rotor part 11, make its pump shaft reach the high speed rotating of 5000-15000r/min.Necessary lubricated for the high speed rotating that solves gear, the utility model is provided with oil removal cover 12 below low speed rotor part 11, make lubricant oil bring high speed rotor parts 3 by the method for splashing with lubricant oil.Because pump shaft is to rotate,, when it is turned round, and do not produce high temperature on high speed so adopted high speed machine to seal 8 and at the middle part of pump shaft towards sap cavity 9 under fast state.The utility model component are few, and interchangeability is good, long service life, and the condition that can be useful in different operating modes is used, and noise is low, cost is low, efficient is high, has higher popularization, use value.
