Description
Technical Field
The utility model relates to a hot-water pump starting control device for rubber production.
Background
Currently, most of the starting modes of the hot water pumps of rubber enterprises in China are directly started by contactors. This way of starting has the following drawbacks: 1. the three-phase alternating current asynchronous motor has very high direct starting current which is generally 4-7 times of the rated current of the motor, and is equivalent to the instant starting current of the existing hot water pump which can reach hundreds of amperes, so that the impact on the load of a power grid is large, and hidden dangers exist. 2. The starting torque of the motor is correspondingly increased to 2-4 times of the rated torque, which means that the motor bears high mechanical load during starting, so that the failure rate of the equipment is increased. 3. The high current when directly starting makes the main circuit contact generate heat, which is very easy to cause component damage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a hot-water pump start control device is used in rubber production to solve above-mentioned technical problem.
In order to realize the purpose, the utility model adopts the following technical scheme:
a hot water pump starting control device for rubber production comprises a control cabinet, a first hot water pump and a second hot water pump, wherein a round hole is formed in the top of the control cabinet, external electricity enters the control cabinet from the round hole, the external electricity penetrates out of the control cabinet after passing through components in the control cabinet, the first hot water pump and the second hot water pump are both connected with the control cabinet, a cabinet door in hinge connection is arranged on the front surface of the control cabinet, a plurality of guide rails mounted with screws are arranged in the control cabinet, a circuit breaker is mounted on the uppermost guide rail, a control terminal row is mounted on the left side of the circuit breaker, a soft starter is arranged below the circuit breaker and mounted on the guide rails, a first switching contactor and a second switching contactor are arranged on the left side of the soft starter, a voltmeter is mounted on the cabinet door, a switching control knob is mounted below the voltmeter, the circuit breaker is electrically connected with the outside, and the output end of the, the output end of the soft starter is connected with the switching control knob and the voltmeter, the switching control knob is connected with the first switching contactor and the second switching contactor, the output end of the first switching contactor is connected with the first hot water pump, and the second switching contactor is connected with the second hot water pump.
Preferably, the soft starter is LCD OPERATOR 37 KN.
Preferably, the model of the circuit breaker is QF 100A.
Compared with the prior art, the utility model has the advantages of it is following: the utility model has reasonable design; connect first hot water pump, the second hot water pump through soft starter, when need start first hot water pump, when the second hot water pump, phase control in the soft starter slowly risees motor voltage effective value to 380V, because electric current and voltage are direct proportion relation, so the coefficient that motor voltage can be used to the electric current reduces, motor torque is the quadratic relation with voltage simultaneously, consequently starting torque is the quadratic coefficient with motor voltage and reduces, just so reached the effect that the motor can the smooth start, can also monitor motor behavior simultaneously.
