Problems solved by technology

[0003] At present, the traditional procedure for motor installation inspection is generally to inspect the size and uniformity of the air gap, and the monitoring of the uniformity of the gap is generally cumbersome, and often requires repeated disassembly and assembly of the motor base, which consumes a lot of manpower and material resources, and often prolongs Larger economic losses caused by the construction period

Embodiment Construction

[0021] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0022] A method for checking whether the motor base is firmly installed, characterized in that the steps are as follows:

[0023] Step 1, the installation of the sensor,

[0024] Install the base sensor 2 on the motor base, install the base sensor 3 on the base below the base, and install the phase detection sensor 1 on the surface of one end of the exposed journal of the motor. The phase detection sensor 1 is a laser sensor. A reflective strip is pasted on the rotor to reflect the light beam of the phase sensor 1, and the base sensor 2 and the base sensor 3 are both vibration sensors;

[0025] Step two, start th...

Abstract

The invention discloses a method for checking whether a motor support is installed firmly or not. The method includes the steps of sensor installation, motor starting, vibration signal acquisition and data analysis and determination. The positions where pads are not firmly installed can be rapidly determined according rotor dynamics theory by adjusting measuring point positions. The vibration of the lower portion of a motor and the vibration of the ground are compared, and a practical and novel method for checking whether motor support is installed firmly or not is summarized through lots experiments. Whether pads are firmly installed and which pad is not firmly installed can be determined through test for one time, and specific installation defects can be analyzed through vibration magnitude and phase deviation. A reinforcing scheme is determined to prevent complex work of repeated dismounting motors. The service life time of a motor is indirectly prolonged, the structure is simple, and the method is provided to be practical through practice.

Description

technical field [0001] The invention relates to the technical field of motor installation, in particular to a method for quickly checking the installation firmness of a motor base. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction, or converts one form of electrical energy into another form of electrical energy. A motor converts electrical energy into mechanical energy (commonly known as a motor), and a generator converts mechanical energy into electrical energy. The motor is represented by the letter "M" ("D" in the old standard) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. [0003] At present, the traditional procedure for motor installation inspection is generally to inspect the size and uniformity of the air gap, and the monitoring of the uniformity of the gap is generally cu...
