Abstract
The utility model relates to a pump head assembly for a high-power high-pressure pumping set. A pump head body is of a three-valve-port structure, and a valve set is mounted in each valve port. Each valve comprises a liquid inlet valve seat, an O-shaped sealing ring A, a valve plate, a liquid feeding and discharging spring, a liquid inlet valve deck, a spring, an O-shaped sealing ring B, a liquid discharging valve seat, a liquid discharging valve deck and an O-shaped sealing ring C. The pump head body is formed by machining 40CR structural alloy steel, the pump head body is in a cuboid shape in appearance, and the size of the thickness part, which is the same as the valve ports in the axial direction, of the pump head body, is 125mm. The pump head assembly for the high-power high-pressure pumping set has the advantages that by the way of improving the structure of the pump head assembly, the size of the thickness part of the pump head body of the three-valve-port structure is reasonably increased, the high-power high-pressure pumping set is made to have the advantages of being high in rated pressure, 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 pump head assembly 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.Pump head assembly 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 architecture advances scheme 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 pump head assembly for high-power high voltage pump group, comprise pump head body, it is characterized in that, pump head body is three valve opening structures, one group of valve member is installed in each valve opening, and described valve member comprises feed liquor valve seat, O RunddichtringO A, valve plate, enters discharge opeing spring, feed liquor valve gap, spring, O RunddichtringO B, discharge opeing valve seat, discharge opeing valve gap and O RunddichtringO C;
Pump head body adopts 40CR Alloy Constructional Steel to process, and the profile of pump head body is cuboid, and it is of a size of 125 millimeters with the axial consistent thickness part of valve opening.
The beneficial effects of the utility model are: by the improvement of pump head assembly structure, pump head body thickness portion size to three valve opening structures rationally increases, 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.
