Abstract
Provided is a determination device for an oil absorption expansion rate of a sealing element. A double-layer force measuring rack is placed on a desk type electronic balance seat, a lower layer of the rack is in an inverted concave shape and is arranged above a balance weighing disk, a round hole is arranged in the center of an upper layer of the rack, an arch-shaped hanging frame is inserted into the rack from the back of the rack, a round disk is welded on a lower rod of the hanging frame and placed on the balance weight disk, an upper rod of the hanging frame is suspended above the round hole in the upper layer of the rack, the arch-shaped hanging frame only contacts the balance weighing disk and does not contact the double-layer rack, and an electronic balance is connected with a computer through a data line. The computer is used to record data automatically and calculate the density and the oil absorption expansion rate of the sealing element. After the force measuring rack and the arch-shaped hanging frame are taken down, the determination device turns to be an ordinary electronic balance.
Description
Technical field
The utility model relates to a kind of seal oil suction expansivity determinator, and more particularly, the utility model relates to a kind of determinator that can automatically measure, calculate simultaneously seal density and oil suction expansivity, belongs to rubbery material checkout equipment field.
Background technology
Seal comprises the sealing gasket made by rubber, rubber-plastics, rubber-fibre reinforced composite, O-ring seal, oil sealing etc., have a wide range of applications in fields such as communications and transportation, oil gas conveying, hydraulic pressure transmission, mechanical drive, especially the internal combustion engine locomotive such as aviation, automobile requires seal that better high temperature high voltage resistant and oil resistance are arranged, and the density of seal and oil suction expansivity have important impact to the High Temperature High Pressure mechanical and physical performance of seal, therefore, the density of Accurate Determining seal and oil suction expansivity are to detect the important method of property of sealing piece.
At present, the method of the mensuration encapsulant density that GB GB/T22308-2008 proposes is the quality geometric method, namely distinguish first the quality of weighing encapsulant oil suction front and back, then measure the volume of encapsulant oil suction front and back with geometric method, thereby calculate density and the oil suction expansivity of encapsulant.Obviously, this method only is suitable for having the seal of regular geometric shapes, and precision is not high, is unsuitable for the measurement of polymorphic structure seal.
For this reason, people have manufactured and designed the meausring apparatus of various structures according to Archimedes' principle, be used for measuring quality and the volume of polymorphic structure material, its common ground is that dynamometric system (comprising mechanical or pulling force sensor) all is overhead, can only be used for suspension type and weigh, can not be used for dull and stereotyped press-down type and weigh, therefore, can only be exclusively used in weighing method and measure density of material, can not be also used as common meausring apparatus.
Summary of the invention
The purpose of this utility model is to provide a kind of seal oil suction expansivity determinator, can overcome the deficiency of existing equipment, can be used for measuring density and the oil suction expansivity of seal, again can be as the usefulness of ordinary electronic balance.
The purpose of this utility model is achieved through the following technical solutions: a kind of seal oil suction expansivity determinator is provided, comprises electronic balance, dynamometry stand, Bow-shaped hanger frame and computing machine; Dynamometry stand frame is above electronic balance, and Bow-shaped hanger frame is inserted and placed on the platform from dynamometry stand back, and electronic balance is connected with data line with computing machine.Described electronic balance is the common precise electronic balance with data-interface, is connected with computing machine by data line; Described dynamometry stand is a kind of movably double-deck stand, and stand lower floor becomes inverted spill, and frame is above platform, and the center, upper strata has a circular hole; Described Bow-shaped hanger frame inserts from double-deck stand back, plectane of Bow-shaped hanger frame lower beam welding, and be placed on the platform, play stable Bow-shaped hanger frame, the suspension bracket upper boom is suspended in stand upper strata circular hole top, and Bow-shaped hanger frame contacts without any with the dynamometry stand except with platform contacts.
Principle of work of the present utility model and method of operating be, during measurement liquid container or well heater is placed on the dynamometry stand lower plywood, and seal to be measured is hung first at the Bow-shaped hanger frame upper boom w that weighs from circular hole
1, then hang the w that weighs in the immersion fluid
2, seal is hung to immerse to take out behind the heating certain hour in the oil again and dries, and hang over the w that weighs on the suspension bracket
3, and then hang the w that weighs in the immersion fluid
4, the automatic record data of computing machine and formula
Calculate the density of seal and by formula
The beneficial effects of the utility model are, the seal oil suction expansivity determinator that provides is to mount movably dynamometry stand and Bow-shaped hanger frame on the basis of ordinary electronic balance, be used for measuring density and the oil suction expansivity of seal, remove dynamometry stand and Bow-shaped hanger frame, again can be as the usefulness of ordinary electronic balance.Have advantages of simple in structure, easy to manufacture, easy to operate, quick and precisely, function is multiplex.
