Description
Technical field
The utility model is related to measure pump technical field.
Background technology
Metering pump be it is a kind of can meet various stringent technological process needs, flow can be stepless within the scope of 0-100%
It adjusts, for conveying liquid（Especially corrosive liquids）A kind of special positive displacement pump.Metering pump is also referred to as constant displacement pump or proportioning pump, meter
Amount pump belongs to reciprocating displacement pump, used for precise metering, usually requires that the steady state accuracy of metering pump is no more than ± 1%.With
For modernization industry towards automation mechanized operation, the continuous development of long-distance automatic control this situation, the matching of metering pump is strong, suitable
Answer medium（Liquid）Extensive advantage particularly looms large.
But traditional mechanical metering pump, complicated, high processing costs, installation and maintenance are difficult, and performance is unstable.
Invention content
In order to solve the above problem existing for tradition machinery metering pump, the utility model provides a kind of external signal control
Type metering pump.
The utility model technical solution used for the above purpose is：A kind of metering pump, the connection of 14 side of shell
Pump head 11, motor 1 is installed on installation import valve module 13 and outlet valve module 10, top on pump head 11, and motor 1 exports axis connection snail
Bar turbine mechanism 2, worm screw turbine mechanism 2 connect eccentric cam 3, eccentric cam 3 connect connecting rod 4,4 front end of connecting rod connection be located at into
The diaphragm 12 of the channel side of mouth valve module 13 and outlet valve module 10,4 outside of connecting rod are equipped with resetting spring 5；Stroke adjusts hand
Handle 6 passes through 7 connecting worm turbine mechanism 2 of axis.
Protection plug 9 is equipped between the shell 14 and pump head 11.
11 inside of the pump head is equipped with leakage mouth 8.
The external signal control type metering pump of the utility model, it is simple and reasonable, processing cost is low, easy to maintain, and
And can be controlled by external signal, greatly improve work efficiency the performance with metering pump.

Specific implementation mode
The metering pump configuration of the utility model installs import as shown in Figure 1,14 side of shell connects pump head 11 on pump head 11
Motor 1,1 output shaft connecting worm turbine mechanism 2 of motor, worm screw turbine are installed in valve module 13 and outlet valve module 10, top
Structure 2 connects eccentric cam 3, and eccentric cam 3 connects connecting rod 4, and 4 front end of connecting rod connects the diaphragm 12 in pump head 11, set outside connecting rod 4
There is resetting spring 5；Stroke regulation handle 6 connects resetting spring 5 by axis 7, and it is eccentric convex to adjust to control the position of resetting spring 5
Wheel 3 and the contact of connecting rod 4 are equipped with to adjust the length of stroke of pump, between shell 14 and pump head 11 and protect plug 9, in pump head 11
Side is equipped with leakage mouth 8.
In use, driven by motor 1, the rotary motion of motor is slowed down through worm screw turbine mechanism 2, by 3 turns of eccentric cam
It is changed to the reciprocating motion of connecting rod 4, resetting spring 5 makes connecting rod reset, and changes length of stroke by adjusting stroke regulation handle 6.
Connecting rod 4, which moves back and forth, drives diaphragm 12 and valve collective effect, and pressure and vacuum necessary to pumped (conveying) medium are generated in pump head 11, with
Generate the feed flow of pulsation.
The external control signal of acceptable contact type or analog quantity type.The control section of contact type has：One power connection,
One power switch for carrying indicator light, the bi-colour LED of a display operation/failure, a two-stage liquid level input, one
Measure monitor inputs, an external control contact input, a mode conversion switch, the electronic security(ELSEC) of a monitoring motor running condition
Device.The control section of analog quantity type has：One power connection, a power switch for carrying indicator light, a display operation/
The bi-colour LED of failure, a two-stage liquid level input, a measure monitor input, an external control analog signal input, one
Mode conversion switch, the electronic safety device of a monitoring motor running condition.
