The reciprocating type plunger accurate variable device comprises a regulating sleeve (1) with thread, and a flange sleeve (2) is connected with the regulating sleeve (1) through the thread. One end of a storage sleeve (3) is disposed in the regulating sleeve, and the other end is disposed in the flange sleeve. An output flux regulating plunger (4), which can change the suction volume of the plunger pump, is disposed in the front end of the storage sleeve. A reset component (7) is disposed on the tail end of the storage sleeve, and the flange sleeve and the regulating sleeve are provided with scales (19). The utility model can be used for the output flux regulation of the pump.
Description
Technical field:
The utility model relates to the device in a kind of fluid transmission control field, is specifically related to a kind of reciprocating type plunger precision and quantity-variation device.
Background technique:
At present, conventional reciprocating plunger pump output flow variable all obtains the change of output flow in the plunger stroke mode that changes plunger pump.For example, by change the swash plate angle or change bent axle, eccentric throw of eccentric realizes the change of plungers pump plunger stroke, thereby reach the purpose that realizes changing output flow.And the stressed relatively complexity of the variable device of these modes, accuracy of manufacturing height, particularly the variable mode noise by worm gear drive change throw of eccentric are big, the rate of fault height.
Summary of the invention:
The purpose of this utility model provides a kind of plunger intake that directly accurately changes reciprocating plunger pump, thereby makes reciprocating plunger pump obtain the reciprocating type plunger precision and quantity-variation device of high-precision demand volume under the constant situation of plunger stroke.
Above-mentioned purpose realizes by following technological scheme:
Reciprocating type plunger precision and quantity-variation device, its composition comprises: screwed adjustment sleeve, pass through scyewed joint flange cover in the described adjustment sleeve, storage cover one end is contained in that the other end is contained in the described flange cover in the described adjustment sleeve, described storage cover Inner Front End is equipped with the output flow pilot plunger of the intake that changes plunger pump, described storage cover tail end is equipped with reset assembly, and described flange cover has footage number with described adjustment sleeve connection part.
Described reciprocating type plunger precision and quantity-variation device has in the described storage cover by regulating the described inner chamber of the Volume Changes hydraulic pressure cavity that causes when regulator bolts obtains pressure and holds the to-and-fro motion of output flow pilot plunger.
Described reciprocating plunger pump precision and quantity-variation device, described reset assembly comprise the piston that is connected with described storage cover tail end, are positioned at the Returnning spring of described piston opposite side, and described Returnning spring connects the pressure regulation pad; On the blanking cover of described adjustment sleeve tail end regulator bolts is housed, has the card key between described blanking cover and the described adjustment sleeve, described storage cover tail end has buckle closure, described buckle closure and described blanking cover are equipped with the bleeder screw that imports into wherein, and described output flow pilot plunger side in described storage cover has the technology screw plug.
Described reciprocating plunger pump precision and quantity-variation device, described flange is set with supporting ring and seal ring, and described storage cover front end is equipped with seal ring, and described piston is equipped with piston packing; Use bolt between described flange cover and the corresponding plunger cavity of reciprocating plunger pump.
Beneficial effect:
The utility model is accurately adjusted the position of output flow pilot plunger by spiral, thereby adjusts the intake of reciprocating plunger pump, thereby a kind of new variable mode is provided.Owing to realize the output flow pilot plunger is controlled by the fluid pressure of regulating in the surplus storage cover, and liquid is worked in the storage cover under the low pressure operating mode, simultaneously, piston displacement distance can design less, thus spring, major part reliable operations such as seal ring, noise free, the life-span is long; Because liquid absorption can be regulated separately in each plunger cavity in the multi-cylinder reciprocating pump, so can obtain the more accurate flow that needs.
When the reciprocating plunger pump that this device is housed needed variable, by rotary regulating sleeve, the scale that puts according to flange was determined the position of required flow.At this moment, when moving to left, the plunger of reciprocating plunger pump sucks liquid, the Flow-rate adjustment plunger enters in the cylinder body of reciprocating pump plunger under the suction of storage cover internal pressure and plungers pump plunger synchronously and occupies corresponding volume, reduces on request or the liquid absorption of (increase) plunger; When the plunger of reciprocating plunger pump moved to right, plunger head pressure fluid also promoted the output flow pilot plunger and moves to right synchronously, obtains required flow.Simultaneously, regulate liquid in the storage cover and promote piston and move right the storage cavity volume is enlarged, absorb the unnecessary flow that is produced when the output flow pilot plunger moves to right.
Liquid absorption can be regulated separately in each plunger cavity in the multi-cylinder reciprocating pump, so can obtain the more accurate flow that needs.
