Abstract
The utility model relates to a gear shaft for a high-power high-pressure pumping set. The gear shaft for the high-power high-pressure pumping set is characterized in that the gear shaft is of a double-gear structure, the structure of a gear A and the structure of a gear B are the same, and angle mirror symmetry of gear teeth is achieved; the gear shaft is formed by machining 40CR structural alloy steel, and the number of the teeth of the gear A and the number of the teeth of the gear B are both 24. The gear shaft for the high-power high-pressure pumping set has the advantages that by the way of improving the structure of the gear shaft, the number of the teeth of a gear of a double-gear structure is reasonably set, the rated pressure of the high-power high-pressure pumping set is increased, the high-power high-pressure pumping set is made to have the advantages of being compact in structure, high in efficiency and capable of regulating flow conveniently, operation can be achieved in high pressure, and the service life is prolonged.
Description
Technical field
The utility model relates to high-power high voltage pump, particularly a kind of gear shaft for high-power high voltage pump group.
Background technique
High-pressure service pump is the high pressure water power equipment that modern industry is conventional, is widely used in coal, mine, metallurgical dephosphorization, Cleaning by High Pressure Water Jet, railway, foundation engineering, boats and ships and cleans rust cleaning, building, automobile and petrochemical industry, communications and transportation, water conservancy and hydropower, national defence, municipal environmental sanitation and various sebific duct, metal tube, the pressure testing of oil drilling wellhead equipment with fields such as pumps.Gear shaft is high-power high voltage pump group vitals, and reciprocating pump is by a fixing Sealing, and a piston seesaws.Reciprocating pump, by reciprocating motion of the pistons, changes the pump chamber swept volume cycle, realizes and sucks and discharge liquid.And the Sealing of plunger pump is arranged on plunger, by a smooth casing wall.It is mainly to utilize plunger to-and-fro motion in pump cylinder, makes to form between plunger and pump wall volume and changes, and repeatedly sucks and discharges liquid and increase the pump of its pressure.Plunger pump generally has better initial stage operating characteristic, its advantage be have that rated pressure is high, compact structure, efficiency is high and Flow-rate adjustment is convenient etc., but it shortcoming be to move too high pressure, working life is also shorter.How to address this problem and just become the problem that those skilled in the art will study and solve.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing for existing design, a kind of gear shaft structure improvement project for high-power high voltage pump group is provided, make that high-power high voltage pump group has that rated pressure is high, compact structure, efficiency is high and Flow-rate adjustment feature easily, can move higher pressure, increase the service life.
The utility model is to realize by such technological scheme: a kind of gear shaft for high-power high voltage pump group, it is characterized in that, and gear shaft is Double-gear structure, and the structure of gear A and gear B is identical, and the angle mirror image of the gear teeth is symmetrical;
Gear shaft adopts 40CR Alloy Constructional Steel to process, and the number of teeth of gear A and gear B is respectively 24.
The beneficial effects of the utility model are: by the improvement of gear shaft structure, the gear number of teeth to Double-gear structure rationally arranges, improved the rated pressure of high-power high voltage pump group, make that it has compact structure, efficiency is high and Flow-rate adjustment feature easily, can move higher pressure, increase the service life.
