Abstract
The utility model discloses a stand-alone oil injection device comprising an injection oil pump. A thermal relay is arranged on a main circuit of the injection oil pump, and the normally-closed point of the thermal relay is in serial connection in a control loop of a contactor. When the circuit and the matched contactor are in overload or phase failure, the normally-closed point of the thermal contactor is switched off, then the coil of the contactor is in power failure, and the main loop of an oil pump motor is switched off by the main contact of the contactor, so that the motor is protected.
Description
Technical field
The utility model relates to a kind of unit fueling injection equipment equipment.
Background technique
The unit fueling injection equipment is the single-point lubricating fitting, is widely used in transmission positions such as exposed gear, tooth bar lubricated of equipment such as mine, metallurgy, electric power, is particularly useful for exposed gear axle lubricated of various separate unit coal pulverizers.
The defective that this unit fueling injection equipment exists is: the injection pump motor main circuit does not have thermorelay, and when the contactor overload of circuit and institute's adapted, the phase failure, control loop is deenergization in time, and Oil pump electrical machinery easily burns.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of unit fueling injection equipment is provided.
In order to solve the problems of the technologies described above, the technological scheme that the utility model is taked is:
A kind of unit fueling injection equipment comprises injection pump, establishes thermorelay at the injection pump major loop, and the normally closed point of thermorelay seals in the control loop of contactor.
When the contactor of circuit and institute's adapted overload, the phase failure, the normally closed point of thermorelay disconnects, the contactor coil outage, and main noddle on contactor disconnects the Oil pump electrical machinery major loop, thus the protection motor.
Description of drawings
Fig. 1 is a control graph of the present utility model;
Among the figure: QF: circuit breaker, FR: thermorelay, KM: contactor, SB: button, HL: tutorial light, M: Oil pump electrical machinery.
Embodiment
Increase the 3UA50 thermorelay at the injection pump major loop; the normally closed point of thermorelay FR is sealed in the control loop of contactor KM; when the contactor of circuit and institute's adapted overload, the phase failure; the normally closed point of thermorelay disconnects; contactor KM coil blackout; main noddle on contactor disconnects the Oil pump electrical machinery major loop, thus the protection motor.Described major loop is composed in series by circuit breaker Q F, contactor KM, thermorelay FR, and control loop is connected in series by normally closed point, the contactor KM coil of stop button SB2, start button SB1, thermorelay FR.
Claims (1)
1. a unit fueling injection equipment comprises injection pump, it is characterized in that, establishes thermorelay at the injection pump major loop, and the normally closed point of thermorelay seals in the control loop of contactor.
