Description
Technical field
The invention belongs to the reciprocating pump technical field, relate to a kind of multi-cylinder circumference layout reciprocating pump valveless assignment method.
Background technique
An operating characteristic of reciprocating pump is flow.Flow refers to follow the to-and-fro motion of piston (plunger), periodically opens and closes by the flow element, alternately be communicated with and block piston (plunger) active chamber and advance, the passage between comb, complete suction and the discharge process of pump.
The reciprocating pump assignment method has two kinds at present, and a class is the valve flow, and another kind of is the non-valve flows such as pintle or thrust plate.
The valve flow is applied in the type reciprocating pumps such as slurry pump, oil pump, high-pressure water pump, chemical pump be many, for delivery of all kinds of media mostly.The common trait of valve flow-distribution reciprocating pump is: have to suck and expulsion valve.Valve relies on valve and the hydraulic difference under valve is opened, and relies on to close from gravity or spring force, and periodic the keying realized flow thereby the to-and-fro motion of piston (plunger) is followed in realization.
The reciprocating pump of valve flow has following shortcoming:
1, working speed is low, generally lower than 400 rev/mins.Therefore specific power (pump rated power/pump weight) is little, and volume is large, Heavy Weight.When rotating speed improved, vibration and noise can increase considerably, and volumetric efficiency significantly lowers.Reason is the speed of response that the quality size of suction, valve affects valve;
2, transmission medium viscosity and impurities state can affect the normal operation of pump.Reason is that the equivalent through-flow bore of valve is less, and fluid resistance is large.The valveless flows such as axle flow, dish flow are used for oil hydraulic pump etc. mostly.The oil hydraulic pump medium is pure hydraulic oil.The feature of this class pump valveless flow is: take axial pump as example, and piston (plunger) circumference layout on liquid cylinder, and rotate together with liquid cylinder.The liquid cylinder that rotates coordinates with static thrust plate, realizes flow.Being the liquid cylinder that rotates with the similar radial pump of axial pump coordinates with static pintle, realizes flow.
The advantage of this type of valveless flow is: eliminated the impact of valve, increased substantially the rotating speed of pump, increased specific power; Increase through-flow bore, reduced the requirement to medium; Compact structure, volume is little, and is lightweight.Shortcoming is: because liquid cylinder is to rotate, it is in the pump of high-power, large flow, high pressure of purpose that this valveless flow mode is unsuitable for being applied in carrying different medium.
Summary of the invention
A kind of method that the purpose of this invention is to provide multi-cylinder circumference layout reciprocating pump valveless flow overcomes the defective that has the flow technology now, to improve reciprocal pump performance.
In order to achieve the above object, the present invention is achieved by the following technical solutions: the method comprises the cylinder sleeve in liquid cylinder, liquid cylinder, piston, synchronous rotary flow spare, main driving axle, the connector in cylinder sleeve; Liquid cylinder is static; N cylinder sleeve is evenly distributed on the liquid cylinder circumference; Piston is done the rule to-and-fro motion corresponding with the main shaft phase place in cylinder sleeve; Synchronous rotary flow spare is connected with main driving axle and synchronous the rotation.
Effect of the present invention and benefit are:
1, static liquid cylinder coordinates with the synchronous rotary flow spare of rotation, realizes flow;
2, can increase substantially the rotating speed of reciprocating pump;
3, effectively reduce requirement to medium, enlarge the reciprocating pump application;
4, noise and vibration have been reduced;
5, improve the specific power of reciprocating pump, reduce the weight and volume of reciprocating pump;
6, part is few, and is simple in structure, improved the reliability of pump.
