Abstract
The utility model relates to an experimental device for testing the reciprocating compressor piston rod sealing filler gas tightness. The experimental device for testing the reciprocating compressor piston rod sealing filler gas tightness is provided with a cylinder having a cylinder chamber. One side of the cylinder is provided with a through hole matched with the piston rod. The wall of the through hole is provided with a dust ring and a sealing ring successively and separately. The other side of the cylinder is axially provided with the cylinder chamber corresponding to the through hole. The upper portion, the middle portion and the lower portion of the outer wall of the tail end of the cylinder chamber are provided with a one-way inlet valve through which a gas can enter the cylinder chamber, a one-way outlet valve through which the gas can be discharged from the cylinder chamber and a capillary pressure measuring pipe which can be used to measuring the pressure separately. An accurately-matched sliding cylinder piston ring is installed in the cylinder chamber. A reset elastic spring is installed between the cylinder piston ring and the cylinder wall. The working cylinder high-pressure environment is simulated by applying a high pressure gas, reciprocating motion is performed through the piston rod, the pressure value in the cylinder is intuitively presented through the height change of the mercury in the capillary pressure measuring pipe, so advantages of calrity, simple structure, high efficiency, rationality and low cost can be realized.
Description
Technical field
the utility model relates to the experimental facilities of piston rod packing filler, especially the bubble-tight experimental provision of a kind of test reciprocating compressor piston rod packing filler.
Background technology
the bubble-tight experimental provision of reciprocating compressor piston rod seal component is a kind of special purpose device to reciprocating compressor piston rod packing performance measurement.Piston rod packing filler is one of strength member of reciprocating compressor, and wherein the sealing of piston rod and annular gap, compressor steel seat hole generally realizes by airtight and watertight padding, and the impermeability of piston rod packing filler and casing wall is being related to the work efficiency of compressor.In working order, in cylinder chamber, be full of compressed gas, the poor sealing of piston ring and piston rod packing can produce compressed Leakage Gas, and the work efficiency of the leakage contribution compressor of piston rod packing filler and the compressed gas of consumption, will make operating cost increase.Impermeability, using the light tightness between piston rod packing filler and cylinder seat hole wall as deliberated index, is reflected indirectly in some countries.The sealing of piston rod packing is extremely important for the industry such as oil, chemical industry, therefore needs piston rod packing filler to carry out impermeability test, finds out the defect in design, makes compressor reach optimum Working.
at present, the domestic device not detecting for the sealing property of piston rod packing filler, cannot ensure whether the sealing property of piston rod packing filler meets the requirement using.
Utility model content
in order to solve in time piston rod packing Reliability of Packing Seal problem, the utility model provides a kind of test reciprocating compressor piston rod packing filler bubble-tight experimental provision, the bubble-tight experimental provision of this test reciprocating compressor piston rod packing filler is by using gases at high pressure analog operation cylinder hyperbaric environment, move back and forth with piston rod, height change by mercury in capillary piezometric tube presents intuitively, very clear, simple in structure, efficient, reasonable, and with low cost.
the utility model solves the technical scheme that its technical matters adopts: the bubble-tight experimental provision of this test reciprocating compressor piston rod packing filler comprises piston rod, dust ring, sealing ring, gas admittance valve, capillary piezometric tube, cylinder chamber, back-moving spring, cylinder piston ring, air outlet valve, cylinder body, the bubble-tight experimental provision of this test reciprocating compressor piston rod packing filler is provided with the cylinder body of a Ge Dai cylinder chamber, cylinder body one side has the through hole mating with piston rod, on through-hole wall, be sequentially with respectively dust ring and sealing ring, the opposite side of cylinder body, corresponding to through hole, the axial cylinder chamber that has, cylinder chamber's end outer wall upper, middle and lower, be separately installed with can air inlet breather cheek valve, the unidirectional air outlet valve that can give vent to anger and capillary piezometric tube that can gaging pressure, the cylinder piston ring of the slip of precision-fit is installed in cylinder chamber, Flexible Reset spring is installed between cylinder piston ring and cylinder wall, when test, in through hole, pack the piston rod of coupling into, dust ring and encapsulant circle, one end of piston rod is suppressed to cylinder piston ring, and constantly firmly push up and press piston rod, now, force value in cylinder is by capillary piezometric tube, can express, if meet the requirements of force value, the sealing property of sealing material circle reaches a standard, otherwise do not pass a test, can not use.
the beneficial effects of the utility model are, the bubble-tight experimental provision of this test reciprocating compressor piston rod packing filler is by using gases at high pressure analog operation cylinder hyperbaric environment, move back and forth with piston rod, height change by mercury in capillary piezometric tube presents intuitively, very clear, simple in structure, efficient, reasonable, and with low cost.
