Go out a kind of metering pump and add skid mechanism, thus this case generates.
Based on this, the application is made.
Utility model content
The drawbacks described above present in skid is added for existing gauge table, it is good, versatile that the application provides replaceability
Metering pump add skid mechanism.
To achieve the above object, the technical solution that the application takes is as follows：
Metering pump adds skid mechanism, is made of function device, UPVC industrial pipes, electric cabinet, aluminium alloy post, described
Function device include drug tube, metering pump, water inlet pipe, evacuated tube, except pulse piping and add pipe, drug tube, water inlet pipe point
Metering pump is not accessed, and metering pump controls its work after metering pump pressurization by electric cabinet and picks out and add pipe, described adds pipe packet
It includes and adds supervisor and pressure control pipe, it is a branch for adding pipe to add supervisor, is sent to toss area progress after counterbalance valve is arranged thereon
Fixed point adds and flowmeter is arranged on the pipeline of pipe for medicine；Pressure control pipe is another branch for adding pipe, is connect simultaneously with evacuated tube
Forming circuit, the pressure for controlling and adjusting entire adding of agent system；Except pulse piping self-measuring pump pick out, thereon setting with
The matching used damper of metering pump and pressure gauge, for eliminating pipeline pulsation.
Further, as preferred：
There are two the flowmeter settings, and flowmeter one and flowmeter are followed successively by along supervisor's medicament direction of travel is added
Two, the two will add supervisor be divided into pipeline before flowmeter one, pipeline after pipeline, flowmeter two between flowmeter one and flowmeter two
Three sections, three sections are respectively set independent ball valve, and after be connected between the two by maintenance pipe, overhaul and be provided with service valve on pipe.Three
Place's valve forms local pipeline transcendent function together；Can only open service valve when flowmeter two overhauls, and close remaining two
Locate ball valve, you can realization, which is not measured, to be added.It is furthermore preferred that the flowmeter one is suspended body flowmeter, flowmeter two is electromagnetism
Flowmeter.
Described adding has picked out spare branch pipe on supervisor, which is connected to by service valve with spare pipe, spare
Guan Shangke continues that next group of spare branch pipe, spare supervisor and metering pump is arranged, and adds supervisor and forms list with spare branch pipe, service valve
Handoff functionality is added between group pumping, the mutually spare effect of every metering pump can be played.
It is provided with filter on the drug tube, filters impurity, foreign matter etc..Preferably, the filter is Y type mistakes
Filter.

Pipe can play the mutually spare effect of every metering pump.
Maintenance pipe service valve forms local pipeline transcendent function together；In flowmeter two（Preferably electromagnetic flowmeter）Maintenance
When can close ball valve five, ball valve six, open service valve, realization, which is not measured, to be added.
Damper and pressure gauge form the effect for eliminating pipeline pulsation together, are the attachmentes that metering pump must be equipped with.Pulsation
Damper smoothly the pipeline pulsation caused by metering pump and can eliminate the water hammer of system, it is by corrosion resistant diaphragm by gas
Body is isolated with the liquid in pipeline, is pulsed by the smooth pipeline of the variation of gas chamber volume, is stored to the energy of pressure fluid
And release.
Safety valve is used for controlling the pressure of whole system.When being more than setting pressure by the pressure of protection system, safety valve
Open, by pressure control pipe, emptying branch pipe, emptying return pipe and evacuated tube, the extra medium of discharge part, to prevent system pressure after
Height of continuing rising；When system pressure is reduced to specified value, safety valve is automatically closed, to ensure system normal operation.
Evacuated tube is emptying, normally closed.Opened when system is out of service or maintenance, for hydrops in emptying system with
And ejected wash water.
UPVC pipelines and accessory possess the drinking water related product hygiene permits that provincial health department issues.
Electric cabinet is used for metering pump start-up and shut-down control, and metering pump signal acquisition integrates a set of advanced PLC module, has remote
Journey communication interface, using unified Industrial Ethernet interface protocol, convenient for being connected with other equipment.
