The biomass crusher should perform vibration signal detection:
Before starting the biomass crusher, various safeguard inspections should be carried out so that the biomass crusher can be put into use with peace of mind. Generally, the crusher includes signal detection such as load, leakage and phase failure protection, in order to avoid equipment overflow and water seepage. And leakage will cause equipment to burn and endanger the normal operation of other equipment. Here, we explain the importance of vibration signal detection.
When the blades of the biomass grinder are entangled with debris in the water, the impeller of the equipment rotates unbalanced, which will cause the equipment to vibrate violently. The piezoelectric vibration sensor is connected to the equipment to detect the vibration of the biomass grinder in a timely manner, and then Understand whether the crusher is operating normally. The sensor is composed of a spring, a mass piezoelectric plate and a base. The sensor base is firmly fixed around the bearing between the motor and the diving equipment to sense the mechanical vibration of the equipment.
When the sensor is vibrated, because the stiffness of the spring is very large and the mass of the mass is correspondingly small, the force of the mass can be considered small. Therefore, the mass feels the same vibration as the base of the sensor and is affected in the opposite direction. Therefore, the mass block has an alternating force proportional to the acceleration acting on the piezoelectric component. Because the piezoelectric component has a piezoelectric effect, alternating charges are formed on its two surface layers.
In addition, in order to instantly check the information of the biomass crusher, temperature sensors, vibration sensors, oil and water probes and float switches were selected for water leakage detection, and the equipment and motors were monitored and protected through control. It is also hoped that The majority of users understand that during the operation of the biomass grinder, the inspection signal of the working status is an information carrier that reflects the normal or abnormal operating status of the equipment, and appropriate inspection methods are an important condition for finding fault information.
