Author: admin Release time: July 7, 2017 Number of visits:

When purchasing JZC350 concrete mixer equipment, many users do not know much about mixing machinery and equipment, and do not know how to use the power control electrical accessories on the mixer? Let me give you a detailed introduction and guidance.

Instructions for the use of 350 concrete mixer power control electrical accessories:

1. The control of the mixing mechanism is completed by the positive and negative transfer of the motor. The mixing starts when the motor is in forward rotation, and the mixed concrete is discharged when it is reversed.

(1) Mixing process: press the button SB1, the contactor KM1 will be automatically locked after being powered on and closed, its main contact will be closed, and the motor M1 will rotate forward after being powered on for mixing. (2) Discharging process: press the button SB2, the normally closed contact of SB2 will be disconnected first, which will make the contactor KMI lose power and release, and the motor M1 will stop running. After the SB2 normally open contact is closed, the contactor km2 will be electrified and automatically locked, and its main contact will be closed, and the motor M1 will reverse to discharge the concrete.

2. The control feeding device on the feeding device is completed by the positive and reverse operation of motor m2. When the motor M2 rotates forward, the hopper rises, and when M2 reverses, the hopper drops. There is no limit position switch SQ1 and SQ2 at the limit position of its ascending and descending operation. In order to ensure the safe operation of the hopper, the electromagnetic brake is used to ensure the safety of the hopper. The specific instructions are as follows:

(1) hopper Rising: press Sb3, contactor KM3 is electrified and self-locking, its main contact is closed, motor M2 is in forward rotation, and hopper rises.

(2) hopper descending: press Sb4, the normally closed contact of Sb4 is opened first, so that the contactor KM3 loses power and releases, and motor M2 stops running. The normally open contact of Sb4 is closed, which makes the contactor km4 powered on and self-locking. Its main contact is closed, the motor M2 reverses and the hopper drops. The automatic stop of hopper up and down is controlled by limit switch SQ1 and SQ2. A position protection switch SQ3 is set at the rising limit position, and a limited position contactor km5 is provided. When the hopper rises and touches SQ1, the limit switch will be out of control, and the hopper will continue to rise and touch SQ3, which will make the contactor km5 lose power, its main contact will be broken, and the hopper will stop immediately.

In order to make the hopper stop at the specified or any position, or to avoid the hopper falling due to sudden power failure, a brake ybo is added in the main circuit of the hopper elevator m2. 3. The water supply system operation is powered by the solenoid valve ev. When water is needed for mixing, press sb7, the solenoid valve is powered on for water supply, and release button sb7 to stop water supply.
