Description
Technical field
The utility model is related to a kind of pump efficiency detection means.
Background technology
In current tobacco business, smell improvement is carried out to tobacco leaf and pipe tobacco by charging and perfuming process, promotes fragrant
Gas, the toughness for transforming tobacco and the need for the aromatic style of novel and unique can be created to meet different smoking taste consumers.
Therefore feed（It is fragrant）Device is a kind of essential equipment in pipe tobacco process.But at present when because pump efficiency is seriously reduced when without
The timely early warning of method, machine repair personnel also can not just safeguard in time, could find, now often can only when charge pump is thoroughly damaged
Change the whole pump housing.And the cost of charge pump is often very high, this necessarily causes the loss of tobacco factory.
It is same only to carry out the overproof alarm of charging when normal production, just at present, it is thus possible to cause in pre-filled process
The middle work early stage feed liquid caused by pipeline blockage or other reasonses, which can not be added and subsequently shut down, causes fault in production and life
Production delay, or even feed liquid mix board accident.
The content of the invention
The purpose of this utility model is to provide a kind of pump efficiency detection means, overcomes existing charging（It is fragrant）Failure of pump can not and
When early warning and cause increase equipment and the shortcomings of maintenance cost.
The purpose of this utility model is achieved through the following technical solutions：
A kind of pump efficiency detection means, including spices tank and charger, spices tank by delivery pump to charger delivery of fragrances,
Wherein, first pressure sensor is provided with the pipeline between spices tank and delivery pump, between delivery pump and charger
Second pressure sensor is provided with pipeline, flowmeter is provided with the pipeline between second pressure sensor and charger,
The first pressure sensor and second pressure sensor connect the input of PLC, the output control conveying of PLC
Pump.
Scheme is further：The output of the PLC passes through a Frequency Converter Control delivery pump.
Scheme is further：It is connected between the input channel of the first pressure sensor and the output channel of flowmeter
One by-pass line, is provided with by-passing valve on by-pass line.
The beneficial effects of the utility model are：The density of stock can be communicated by flowmeter with mass flow and obtained, without again
Individually increase instrumentation, storage cabinet charging of the present utility model（It is fragrant）Pump motor is by transducer drive, and frequency conversion is by PLC programming Controls
Device is controlled, and can monitor the efficiency of pump on-line.The utility model is shifted to an earlier date pre- by monitoring the efficiency of pump in real time when occurring abnormal
Warn and point out maintenance personal to carry out maintaining to pump.
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of pump efficiency detection means, as shown in figure 1, described device includes spices tank 1 and charger 2, spices tank passes through defeated
Pump 3 is sent to charger delivery of fragrances, wherein, first pressure sensor 4 is provided with the pipeline between spices tank and delivery pump,
Be provided with second pressure sensor 5 on pipeline between delivery pump and charger, second pressure sensor and charger it
Between pipeline on be provided with flowmeter 6, first pressure sensor and second pressure sensor the connection PLC 7 it is defeated
Enter, the output control delivery pump of PLC.Wherein：The output of the PLC be controlled by a frequency converter 8 it is defeated
Send pump.
In embodiment, in order to easy to maintenance：The input channel of the first pressure sensor and the output channel of flowmeter
Between be connected with a by-pass line 9, by-passing valve 10 is provided with by-pass line.In the second pressure sensor input
Wind drift gauge valve 11 is additionally provided between pipeline and the input pipeline of first pressure sensor.When wind drift gauge valve is used to repair
Clear by compressed air convection gauge blows.
In actual work, the output of the spices tank 1 is connected with the first threeway 12, and an input of the first threeway leads to
Cross valve 13 and 14 and connect cleaning water source and source of purge gas respectively.The output of first threeway connects described by a filter 15
The input channel of first pressure sensor, a feed back pipeline 16 is additionally provided between the spices tank 1 and charger 2, is being returned
Material returning valve 17 is provided with pipe material, feed back pipeline is connected by the second threeway 18 with charger, charger is passed with second pressure
Pass through the other two-way communication of the second threeway 18 between sensor pipeline at output.
Understand that the efficiency of pump is the ratio between effective power and shaft power of pump according to known technology, formula is η=Pe/P,
The power of pump is commonly referred to as input power, refers to that motor is delivered to the power on pump shaft, so also turning into shaft work
Rate, is represented with P, can be communicated and obtained by PLC and motor inverter；
The effective power of pump is the lift of pump, mass flow, the product of acceleration of gravity, in the situation of known quality flow
Under, the effective power formula of pump is as follows：
Pe = 9.81×Q×H
Q：Mass flow Kg/s；
H：Actual lift m；
Configuration is a set of to flush the import and export position that diaphragm pressure transducer is installed in pump, detects the inlet and outlet pressure of pump,
And then actual lift H=△ P/ of pump are calculated according to formula（9.81 × density）, △ P are the differential pressure of pump discharge and entrance, single
Position is Pa, and the unit of density is Kg/m3.Obtained moreover, density can be communicated with mass flow by flowmeter, without individually increase again
Instrumentation.
During work, charging delivery pump is by Frequency Converter Control, the power output of PLC collection frequency converter, pressure sensing
Device pressure and flow meter data.PLC is by the program of writing and according to delivery pump motor, frequency converter, pressure sensing
The relevant parameter of device and flowmeter, calculates the efficiency of pump, realizes that pump efficiency is detected.
