Abstract
The utility model belongs to the high pressure pump manufacture field, and especially relates to a pressurized cylinder of a high pressure pump, comprising a cylinder body and a plunger slidingly connected to the cylinder body. The utility model is characterized in that the cylinder body is composed of an inner cylinder and an outer cylinder, and the outer cylinder is sleeved out of the inner cylinder. The inner cylinder and the outer cylinder are connected through interference. The utility model has the advantages that the pressurized cylinder is simple in mechanism, the pressurized cylinder of the high pressure pump is divided into two parts of the inner cylinder and the outer cylinder, and the two parts are connected through interference, so that the pressurized cylinder of the high pressure pump has higher anti-compression capability, thereby increasing the service life of the high pressure pump.
Description
Technical field
The utility model belongs to high-pressure service pump and makes the field, relates in particular to a kind of high-pressure service pump pressurized cylinder.
Background technique
High-pressure service pump is applicable to that mainly oil, chemical industry, chemical fertilizer industry use as process pump; Oil field, salt mine are as water injection pump, and steel pipe, pressurized container use as hydraulic test pump; Use as the high-pressure wash scale removal at industrial fields such as building, shipbuilding, chemical industry.High-pressure service pump mainly is made up of power end and fluid end two-part; Fluid end comprises pump head and pressurized cylinder; The high pressure pump power end drives crankshaft rotating, promotes to make the plunger that is arranged in pressurized cylinder do straight reciprocating motion, is issued to suction liquid purpose in the keying effect of pump head inlet valve.At present, high-pressure service pump pressurized cylinder inner casing and outer shell are an integral body, promptly when casting, just pressurized cylinder are cast in aggregates.A little less than the high-pressure service pump pressurized cylinder anti-pressure ability of producing like this, working life is shorter.
The model utility content
The main purpose of the utility model is to overcome the deficiency of above-mentioned technology, and a kind of high-pressure service pump pressurized cylinder is provided, and improves the working life of high-pressure service pump pressurized cylinder.
The utility model adopts following technological scheme for realizing above-mentioned purpose: a kind of high-pressure service pump pressurized cylinder, and the plunger that wrapped cylinder body and be slidingly connected with cylinder body is characterized in that: said cylinder body is made up of inner casing and outer shell, and said outer shell is nested in the inner casing outside.
Said inner casing is connected through interference with outer shell.
Beneficial effect: this use novel mechanism is simple, through the high-pressure service pump pressurized cylinder being divided into two parts of inner casing and outer shell, and both interference is connected, and makes the high-pressure service pump pressurized cylinder have higher anti-pressure ability, has improved the working life of high-pressure service pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment below in conjunction with accompanying drawing and preferred embodiment detailed description the utility model.As shown in the figure, a kind of high-pressure service pump pressurized cylinder, the plunger 2 that wrapped cylinder body 1 and be slidingly connected with cylinder body, said cylinder body is made up of inner casing 1-1 and outer shell 1-2, and said outer shell is nested in the inner casing outside.Said inner casing is connected through interference with outer shell.The interference connection characteristics is simple in structure, and alignment is good, not perforate or groove on the axle, and little to axle weakening, bearing capacity is high, and impact resistance is good.
When assembling, can adopt plunging and two kinds of assembly methods of temperature differential method.Plunging is forced inner casing to be pressed in the outer shell, can damage matching surface inevitably in the process of press in, so reduced the tightness that connects.In order to reduce macrolesion, matching surface should be coated with lubricant oil during assembling.When assembling, the outer shell heating is made its expansion, perhaps the inner casing cooling is made its contraction, also can heat outer shell and cooling inner casing simultaneously, realize assembling smoothly to form the fit up gap, thereby reach purpose of connecting with temperature differential method.The damage of temperature differential method matching surface is less, and tightness is high, and bearing capacity is strong.
This use novel mechanism is simple, through the high-pressure service pump pressurized cylinder being divided into two parts of inner casing and outer shell, and both interference is connected, and makes the high-pressure service pump pressurized cylinder have higher anti-pressure ability, has improved the working life of high-pressure service pump.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (2)
1. high-pressure service pump pressurized cylinder, wrapped cylinder body and with the plunger that cylinder body is slidingly connected, it is characterized in that: said cylinder body is made up of inner casing and outer shell, said outer shell is nested in the inner casing outside.
