Abstract
The utility model provides an electronic control cement drying pump, which comprises a casing 1, a screw pump 2, a screw feeder 3, a motor 4 and a power switch 5, wherein the screw pump 2, the screw feeder 3 and the motor 4 are installed in the casing 1 in turn, and the power switch 5 is installed on the casing 1. The cement drying pump is characterized in that a pressure sensor 6 is arranged in the cavity of the screw feeder 3. The control principle is that the pressure sensor 6 can send out a connection signal connected in series with the power switch 5 when material in the screw feeder 3 reaches to a certain weight, and then the motor 4 is started under the condition of simultaneously communicating with the power switch 5. The electronic cement drying pump provided by the utility model has the advantage that the dry friction owing to insufficient material can be avoided as the motor is started when the material in the screw feeder reaches to a certain weight, thereby prolonging the service life.
Description
Technical field
The utility model relates to dried dredge pump.
Background technique
Existing dried dredge pump is by housing, screw pump, feeding screw, motor, power switch and be contained in temperature transducer in the screw pump chamber.Its control principle is: when lacking material in the screw pump chamber, and screw rod and housing generation dry friction, case temperature raises, and temperature transducer sends the signal control power supply switch, cuts off motor power, reduces wear.The shortcoming of this dried dredge pump is to avoid wearing and tearing.
Summary of the invention
The purpose of this utility model is to provide a kind of dried dredge pump that can not start when lacking material.
The utility model provides a kind of automatically controlled dried dredge pump, comprise housing 1, screw pump 2, feeding screw 3, motor 4 and power switch 5, screw pump 2, feeding screw 3, motor 4 are contained in 1 li of housing successively, power switch 5 is contained on the housing 1, it is characterized in that: pressure transducer 6 is housed in the chamber of feeding screw 3.Its control principle is: when 3 li materials of feeding screw reached constant weight, pressure transducer 6 sent the connection signal of connecting with power switch 5, connected at the same time under the situation of power switch 5, just starting electrical machinery 4.
The automatically controlled dried dredge pump that the utility model provides, its pressure transducer 6 can be flat membrane pressure sensor.
The automatically controlled dried dredge pump that the utility model provides, its pressure transducer 6 and power switch 5 can be one.
The automatically controlled dried dredge pump that the utility model provides, its screw pump 2 can be a helical rotor pump.
The automatically controlled dried dredge pump that the utility model provides, its advantage is: because could starting electrical machinery when material reaches constant weight in feeding screw, dry friction can not take place because of lacking material in dried dredge pump, thus raising prolong working life.
Description of drawings
Fig. 1 is the structural representation of automatically controlled dried dredge pump.
Embodiment
Automatically controlled dried dredge pump, its structure as shown in Figure 1, comprise housing 1, helical rotor pump 2, feeding screw 3, motor 4, power switch 5 peaceful membrane pressure sensors 6, helical rotor pump 2, feeding screw 3, motor 4 are contained in 1 li of housing successively, power switch 5 is contained on the housing 1, flat membrane pressure sensor 6 is contained in the chamber of feeding screw 3, and when 3 li materials of feeding screw reached constant weight, flat membrane pressure sensor 6 sent the connection signal of connecting with power switch 5.
