Abstract
The utility model provides an oval flowmeter, include: the rotatory shaft coupling of casing, rotor and drive rotor, the shaft coupling includes the gear, with gear coaxial arrangement's interior magnet and outer magnet, installs the bearing frame between gear and interior magnet, still including the axle sleeve between bearing frame and gear shaft. Oval flowmeter adopts small -size magnetism shaft coupling to drive the rotor and rotates, and small -size magnetism shaft coupling is small, light in weight to reduce the resistance, be favorable to enlarging the measurement scope, be favorable to enlarging small -bore oval flowmeter's measurement scope very much.
Description
Technical field
The utility model relates to a kind of flowmeter, particularly relates to a kind of oval flowmeter.
Background technology
Oval flowmeter is modal one in volumeter, the fluid flow being widely used in the fields such as oil, chemical industry, food, boats and ships, pharmacy, papermaking controls, it utilizes mechanical measurement element that fluid is continuously divided into single known volume fractiion, successively, is repeatedly full of and the number of times that discharges this volume fractiion fluid carrys out measuring flow volume total amount according to measuring room.Shaft coupling is the significant components of flowmeter, existing oval flowmeter many uses BB17 shaft coupling, BB17 shaft coupling is can meet the demands for during heavy caliber oval flowmeter, but for during small-bore oval flowmeter because BB17 shaft coupling volume is large, weight is large, resistance is comparatively large, limits the measures range of small-bore oval flowmeter.
Summary of the invention
The purpose of this utility model is the deficiency in order to make up prior art, provides a kind of oval flowmeter being provided with small magnetic shaft coupling, and this flowmeter smooth running, measures range are large.
The utility model is achieved through the following technical solutions:
A kind of oval flowmeter, comprise: the shaft coupling that housing, rotor and rotor driven rotate, described shaft coupling comprises gear, with the coaxial hard-wired inner magnet of gear and outer magnet, between gear and inner magnet, bearing seat is installed, between bearing seat and gear shaft, also includes axle sleeve.
Preferably, described axle sleeve is graphite bushing.
The utility model has the advantages that: the BB17 shaft coupling of abandoning tradition, adopt small magnetic shaft coupling rotor driven to rotate, small magnetic shaft coupling volume is little, lightweight, thus reduce resistance, be conducive to expanding measures range, be particularly conducive to the measures range expanding small-bore oval flowmeter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model.As shown in fig. 1, a kind of oval flowmeter, comprise: the shaft coupling 3 that housing 1, rotor 2 and rotor driven rotate, described shaft coupling comprises gear 31, with the coaxial hard-wired inner magnet 32 of gear 31 and outer magnet 33, bearing seat 34 is installed between gear 31 and inner magnet 32, between bearing seat 34 and gear shaft, also includes graphite bushing 35.
When fluid to be measured flows through oval flowmeter, the gear in batch meter rotates by the effect of working fluid, and this rotation is sent to interior outer magnet 32,33 through gear 31, and outer magnet 33 rotor driven 2 rotates, and by rotor 2, flow information is delivered to gauge outfit.Oval flowmeter described in the utility model adopts small magnetic shaft coupling, and volume is little, lightweight, thus reduces resistance, is conducive to expanding measures range, is particularly conducive to the measures range expanding small-bore oval flowmeter.
Claims (2)
1. an oval flowmeter, it is characterized in that, comprise: the shaft coupling that housing, rotor and rotor driven rotate, described shaft coupling comprises gear, with the coaxial mounted inner magnet of gear and outer magnet, between gear and inner magnet, bearing seat is installed, between bearing seat and gear shaft, also includes axle sleeve.
2. oval flowmeter as claimed in claim 1, it is characterized in that, described axle sleeve is graphite bushing.
