Abstract
A digital display screw pump comprises a screw pump body and is characterized in that: an information emitting disc, which is used for magnet installation, is fixedly arranged on the driving shaft of the screw pump body; a magnetic information sensor is fixedly arranged at the same longitudinal position of the information emitting disc on the external side of the information emitting disc; the magnetic information sensor is connected to the signal output terminal of a data processor through a wire; and the signal output terminal of the data processor is connected to the input terminal of a digital display. The digital display screw pump has the advantages of simple assembly, high measuring accuracy, low cost, convenient maintenance, and excellent performance; can be applied to promotion and applications in automation, factory formula quantitative measurement, and medium measurement.
Description
Technical field
The present invention relates to a kind of screw pump, particularly a kind of at the screw pump with digital display device.
Background technique
Screw pump is to be applicable to the industries such as transfer of highly viscous medium, pulsating movement free, self-priming is strong, energy consumption is low, be widely used in oil, chemical industry, metallurgy, machinery, food, power station, naval vessel.
At present, in the transfer pump using in prior art, the not digital display pump with digital display device on single suction 2G screw pump; Measure but load onto flowmeter at pump discharge, because of outlet pressure, to have height to have low, and its accuracy of measuring is difficult to approach true value.In addition, to install rectifier additional before entering flowmeter, pipeline complexity, expense is high, and place of working area increases, and affects again service behaviour.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing defect in above-mentioned prior art, and a kind of screw pump with digital display device is provided.
The present invention has adopted following technical proposal to solve its technical problem: a kind of digital display screw pump, comprise screw pump main body, it is characterized in that: the sender set that is fixedly equipped with dress magnet on the driving shaft in screw pump main body, on sender set lateral direction and the same radially position of sender set, be fixedly equipped with magnetic news sensor, this magnetic news sensor connects the signal output part of a data processing system by wire, the signal output part of described data processing system connects a digital display input end.
The present invention assembles simply, measuring accuracy is high, expense is low, easy to maintenance, excellent performance, and suitable quantitative in automation, plant formula, the aspects such as medium metering are applied.

Fig. 2 is the structural representation of sender set of the present invention;
Fig. 3 is the A-A sectional drawing of Fig. 2;
Fig. 4 is electrical block diagram of the present invention.
In figure, each sequence number is expressed as: 1-screw pump main body; 2-driving shaft; 3-sender set; 3.1-magnet; 4-magnetic news sensor; 5-data processing system; 6-digital display; 7-signalling alarm equipment; 8-signal conditioner; 9-power supply; TB2-signal input part; TB3-Signal Regulation end; Signal output part TB4.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
With reference to Fig. 1～Fig. 3, the present invention includes screw pump main body 1.
The sender set 3 that is fixedly equipped with dress magnet 3.1 on driving shaft 2 in described screw pump main body, is at least equipped with a magnet 3.1, and is fixedly mounted on sender set 3 outer rims on described sender set 3.On sender set 3 described in the present embodiment, be equipped with 12 blocks of magnet 3.1, and uniform along sender set 3 outer rims.In practice, magnet 3.1 quantity can decide according to pump capacity size and measuring accuracy, and magnet 3.1 quantity are many, and signal is just close, and measuring accuracy is just high.
In screw pump main body 1, the same radially position of sender set 3 lateral direction and sender set 3 is fixedly equipped with magnetic news sensor 4.
With reference to Fig. 4, it is E8010 BATTERY that described magnetic news sensor 4 connects a data processing system 5(model by wire) signal input part TB2, the signal output part TB4 of this data processing system 5 connects digital display 6 input ends.
The present invention also connects a signalling alarm equipment 7 at the signal output part TB4 of data processing system 5, provides alarm signal when being metered into improper amount.
In addition, the Signal Regulation end TB3 of described data processing system 5 connects a signal conditioner 8, for the signal value size of regulated signal output terminal TB4.
When the present invention works, sender set 3 rotates with driving shaft 2 and sends magnetic news, is received by magnetic news sensor 4, and this magnetic news sensor 4 converts magnetic information to electrical signal and passes to data processing system 5, issues digital display 6 and show after micro-some chip processed.Digital display can divide three patterns: fixed mode, manually adjustment modes and manual adjustment add micro computer self-regulation mode.
The present invention uses on single suction 2G screw pump, because medium in the Seal cage of screw pump screw rod in the time working is from import in an atmospheric pressure with rotating to outlet all the time, no matter outlet is that high pressure or low pressure pressure before medium leaves screw rod Seal cage are constant, enter zone of high pressure after medium leaves Seal cage before, completed accounting procedure, metering accuracy of the present invention is greatly improved thus.
The present invention also goes on the pumps such as rotor pump, gear pump, XHB spiral rotor pump, and its structure and working principle are basic identical, repeat no more here.
