The universal pulverizer generally uses a motor directly connected to the pulverizing device, and the connection method is simple and easy to maintain. However, if the two are not well connected during the assembly process, the overall vibration of the universal crusher will be caused.
(1) The rotor of the motor is not the same as the rotor of the universal crusher. You can move the position of the motor left or right, or pad the bottom of the motor to adjust the concentricity of the two rotors.
(2) The universal crusher rotor is not concentric. The reason is that the two bearing faces of the rotor shaft are not in the same plane. The copper can be padded on the bottom of the bearing housing, or an adjustable wedge iron can be added to the bottom of the bearing to ensure that the two shaft heads are concentric.
(3) The vibration of the crushing chamber is large. The reason is that the coupling of the coupling and the rotor is not uniform or the mass of the flat hammer inside the rotor is not uniform. According to different types of couplings, the corresponding method can be adopted to complete the connection between the coupling and the motor: when the mass of the hammer is not uniform, each group of hammers must be re-selected to make the symmetrical hammers, so that the hammers are symmetrical. The chip error is less than 5G.
(4) The original balance was destroyed. After the motor is repaired, a dynamic balance test is required to ensure the overall balance.
(5) The anchor bolts of the universal pulverizer system are loose or the foundation is not strong. When installing or repairing, the anchor bolts should be evenly tightened. Between the foundation of the foundation and the pulverizer, a shock absorbing device should be installed to reduce vibration.
(6) The hammer is broken or pulverized in the room with hard debris. These will cause the rotor to rotate unbalanced, causing the whole machine to vibrate. Therefore, it is necessary to check regularly for hammers with severe wear. When replacing, it should be replaced symmetrically; if abnormal sound occurs during the operation of the crusher, stop it immediately and find the cause and deal with it in time.
(7) The universal grinder system does not match the connection of other equipment. For example, improper connection of the feed pipe and the discharge pipe may cause vibration and sound generation. Therefore, it is not appropriate to use a hard joint for these joints, and it is preferable to use a soft joint.
