Abstract
Self-controlled type gear pump grouter, comprises motor, shaft coupling, gear pump, and it also has pressure transmitter and frequency variator, and the output tube of gear pump is connected with pressure transmitter.The output port of pressure transmitter is connected to the input end of frequency variator.Inverter output terminal mouth connects motor, and the rotating shaft of motor is connected by shaft coupling with gear pump rotating shaft.When self-controlled type gear pump grouter starts to work, the output tube internal pressure of gear pump is just set up, overpressure is also very low, at this moment low-voltage signal is passed to frequency variator by pressure transmitter, frequency variator changes the power supply frequency of motor, thus corresponding raising rotating speed, accelerate grouting flow, improve filling speed, the change procedure of whole speed and flow is the control of automation.
Description
Technical field
The utility model relates to grouting machine, especially " self-controlled type gear pump grouter ", is the equipment utilizing gear pump to be in the milk.
Background technique
Old-fashioned gear grouter, because motor speed is constant, so only have a kind of speed operation, can not according to pressure change during grouting, change flow, therefore efficiency is lower.Chinese Patent Application No.: 200520040412.4 " pressure boost grouting pumps ", grouting pump comprises a storage vat, this storage vat is installed on a movable base, first port of a three-way pipe is connected with the bottom outlet of this storage vat by a safety check, second port of this three-way pipe is connected with a supercharging device, and the 3rd port of this three-way pipe is connected with a long duct by a safety check.Adopt the pressure boost grouting pump of this kind of structure, due to its manually pressurized cylinder material is squeezed into conduit from storage vat, then by conduit be delivered directly to need grouting position.This suction booster just manually carrys out supercharging, can not realize automatic control.
Summary of the invention
In order to further improve the equipment chain of grouter, the utility model provides a kind of self-controlled type gear pump grouter, tries hard to, by the pressure change in grouting pipeline, realize flow automation and regulate.
The utility model solves the technological scheme that its technical problem adopts: self-controlled type gear pump grouter by, pressure transmitter, send slurry pipe, gear pump, shaft coupling, motor, control box, pressure control plate, frequency variator form, the output tube of gear pump is connected with pressure transmitter.The output port of pressure transmitter is connected to the input end of frequency variator.Inverter output terminal mouth connects motor, and the rotating shaft of motor is connected by shaft coupling with gear pump rotating shaft.
Working principle is, when self-controlled type gear pump grouter starts to work, the output tube internal pressure of gear pump is just set up, overpressure is also very low, at this moment low-voltage signal is passed to frequency variator by pressure transmitter, and frequency variator changes the corresponding raising rotating speed of power supply frequency of motor, accelerates grouting flow.Otherwise at the end of grouting is fast, the pressure in grout pipe raises, pressure transmitter by too high pressure signal transmission to frequency variator, frequency variator changes the corresponding reduction rotating speed of power supply frequency of motor, and ensure that motor can run well safely, the change procedure of whole speed and flow is all the control of automation.
The beneficial effects of the utility model are, self-controlled type gear pump grouter by, pressure transmitter, send slurry pipe, gear pump, shaft coupling, motor, control box, pressure control plate, frequency variator to form, the output tube of gear pump is connected with pressure transmitter.When self-controlled type gear pump grouter starts to work, the output tube internal pressure of gear pump is just set up, overpressure is also pressed very much, at this moment low-voltage signal is passed to frequency variator by pressure transmitter, frequency variator changes the corresponding raising rotating speed of power supply frequency of motor, accelerates grouting flow, improves filling speed, and energy-saving safety, the change procedure of whole speed and flow is the control of automation.
Accompanying drawing illustrates and further illustrates the utility model below in conjunction with drawings and Examples
