Abstract
The utility model relates to a lubrication pump, in particular a lubrication pump with a motor protection device. The structure of the lubrication pump comprises an oil tank and a pump body, wherein the pump body is provided with pump elements; the bottom of the oil tank is connected with the pump body; the bottom of the pump body is connected with a motor outside which a motor protection cover is arranged; and the motor protection device is arranged between the motor and a power supply. Compared with the prior air, the utility model has the characteristics of rational design, simple structure, convenient mounting, long service life and lower fault rate.
Description
Technical field
The utility model relates to a kind of lubricant pump, specifically provides a kind of lubricant pump that has electric motor protective device.
Background technique
Lubricant pump under the prior art, because obstruction of the oil circuit of lubricating point or subsequent element such as filter, distributor stop up, may cause lubricant pump under high pressure, high load, to be worked, time has been grown, may cause burn-down of electric motor, even, directly cause lubricant pump stuck because pumping pressure is too high or grease is unclean, motor does not turn round, and finally burns.
Summary of the invention
The utility model is at above problem, and a kind of lubricant pump that has electric motor protective device is provided, and it is provided with electric motor protective device between the motor of power supply and lubricant pump, can effectively avoid motor to break down and the situation of burning.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of lubricant pump that has electric motor protective device comprises oil drum, the pump housing, and described oil drum bottom connects the pump housing; Described pump housing bottom connects motor, and there is the electric motor protecting cover described motor outside, is provided with electric motor protective device between motor and the power supply.
A kind of lubricant pump that has electric motor protective device of the present utility model; its protective gear principle is: when motor load increases; magnitude of current also is directly proportional and becomes big; we set the maximum value of an electric current; when electric current reaches this value; protective gear is cut off the electricity supply, and to reach protection motor purpose, can add such as prompting functions such as buzzing warning or light signals simultaneously.After starting the input power supply once more, the protective gear de-preservation is normally to motor power supply (certainly, if the reason that causes motor load to increase is not got rid of, protective gear will be cut off the electricity supply again very soon).
The lubricant pump motor has the sense of rotation requirement; when being unkitted protective gear, power line both positive and negative polarity connection difference can cause motor to rotate to two kinds of directions, has added a device on this block protection device chip; power line is connect arbitrarily, and motor only rotates to a direction of needs all the time.
Protective gear has voltage stabilizing, the effect of balance input voltage: when supply voltage had fluctuation, this protective gear can automatic immediate be adjusted voltage, guaranteed the definite value of the voltage of input motor for regulation.A rotating speed that keeps the motor regulation.
Be provided with motor speed-regulating and two knobs adjusting Motor torque in the circuit, can adjust motor speed and moment of torsion according to actual needs.
A kind of lubricant pump that has an electric motor protective device of the present utility model compared with prior art, have reasonable in design, simple in structure, easy for installation, working life for a long time, reduce the characteristics of electrical fault rate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural representation that has the lubricant pump of electric motor protective device;
Fig. 2 is a kind of circuit theory diagrams of electric motor protective device of the lubricant pump that has an electric motor protective device;
Fig. 3 is a kind of circuit theory diagrams of electric motor protective device of the lubricant pump that has an electric motor protective device.
Embodiment
Below in conjunction with the drawings and specific embodiments a kind of lubricant pump that has electric motor protective device of the present utility model is further described.
As shown in Figure 1; a kind of lubricant pump that has electric motor protective device; comprise oil drum 1; described oil drum 1 below is provided with the pump housing 3; on the described pump housing 3 pump element 2 is arranged, the described pump housing 3 bottoms connect motor, and there is electric motor protecting cover 4 the motor outside; be provided with electric motor protective device between motor and the power supply, electric motor protective device is in the electric motor protecting cover.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
Claims (1)
