Abstract

The utility model relates to an analyzer for on-line viscosity analysis meter, which is characterized in that the utility model comprises a left and a right columnar connectors of which the lower ends are provided with holes, capillary pipes, protective pipes of the capillary pipes, a left and a right casing pipes of the capillary pipes, and end connectors, wherein, the capillary pipes are penetrated through the holes of the connectors, the centers of the radial groove holes of the two sides of the capillary pipes are coincident with the axes of the connectors, and simultaneously, the capillary pipes are fixedly welded with the connecting points of the connectors; the protective pipes of the capillary pipes are sheathed outside the capillary pipes and welded with the connectors into a whole; the left and the right casing pipes of the capillary pipes are positioned between the two sides of the capillary pipes and the protective pipes of the capillary pipes and can freely move; the end connectors are sheathed outside the two extended sides of the capillary pipes and fixedly welded with the columnar connectors. The length of the capillary pipes is 122 millimeters, and the center distance of the groove holes is 92 millimeters. The utility model has the advantages of high precision, good repeatability and convenient processing, installation and maintenance.

Description

The analyzer that online viscosity analyser is used

The utility model relates to analyzer that a kind of online viscosity analyser uses and belongs to the analyzer that the on-line analysis instrument uses and make the field.

The analyzer of using as online viscosity analyser is by kapillary and protects the auxiliary equipment of usefulness to constitute at present, and kapillary wherein generally adopts the stainless steel straight tube of 2 * 0.5 millimeters of φ, and length is 35 millimeters.The shortcoming of this analyser be complex structure, seal point many, be easy to leak, greatly and also easy-maintaining not of line service amount.

It is a kind of simple in structure, tight that the purpose of this utility model is to provide, the analyzer that the in-line analyzer that is easy to safeguard is used, this is to measure oil viscosity with the principle of kapillary pressure: have two slotted eyes near the place, two ends along the caliber direction at kapillary, the kapillary two ends are the flow orifice of turnover measured medium, when measured medium flows through kapillary, just on pipe, produce pressure loss, promptly represented the viscosity number of measured medium at the pressure difference of the position of these two slotted eyes.

Of the present utility model being characterised in that: it contains the upper end has connection to use screw thread and a porose left side, middle part, lower end; right two cylinder-shaped joints 5; through a left side; the kapillary 2 that must be respectively firmly weld in itself and the junction of cylinder-shaped joint 5 simultaneously with the dead in line of two cylinder-shaped joints 5 in the hole at middle part, right two cylinder-shaped joint 5 lower ends and the center of the slotted eye that its two side pipes footpath direction is opened; be positioned between two slotted eyes of kapillary 2 and be placed in outside the kapillary 2 simultaneously again the kapillary protection tube 3 that is welded into one securely with cylinder-shaped joint 5, kapillary protection tube 3 two ends and be enclosed within kapillary 2 with kapillary protection tube 3 between again can be free movable two capillary sheaths 4 and entangle outer kapillary 2 of stretching in cylinder-shaped joint 5 both sides and with the cylinder-shaped joint 5 firm end connectors 1 that weld.

Use proof: it has reached gives the phase purpose.

In order in conjunction with the embodiments the utility model to be done detailed describing below, now as follows present specification used accompanying drawing and numbering brief introduction:

The longitudinal section of the analyzer that Fig. 1, the online viscosity analyser that the utility model proposes are used.

Embodiment:

Ask for an interview Fig. 1.The 2nd, the kapillary that φ is 2 * 0.5 millimeters; be the stainless steel straight tube; pipe range is 122 millimeters; centre distance between the slotted eye of both sides is 92 millimeters; use for the pressure difference; the 5th, there is the cylinder-shaped joint of 2.2 millimeters of the porose φ in connecting thread lower end the upper end; it is positioned at the both sides of kapillary 2, a left side; the right side respectively has one, and its axis must overlap so that impulse with the center of slotted eye; guarantee accuracy of instrument; the 3rd, between two slotted eyes of kapillary 2 and be placed in kapillary protection tube outside the kapillary 2, its two ends and cylinder-shaped joint 5 are welded into one, and 4 is two capillary sheaths; be distributed in the both sides of kapillary protection tube 3, be enclosed between kapillary 2 and the kapillary protection tube 3 and can be free movable.1 is two end connectors, is enclosed within the overhanging both sides of kapillary 2 respectively.Kapillary 2, end connector 1 they respectively with the junction of cylinder-shaped joint 5, firmly welding can not be leaked the corresponding maintenance workload that also reduced.More than each in addition part all make with the 1Cr18Ni9Ti stainless steel.Its four overhanging connector is for usefulness is installed.

Analyzer precision height, good reproducibility, processing, the installation, maintenance that the utility model proposes are all very convenient.

Claims
