1 Hidden danger of Roots fan installation

1.1 Basic Equipment

In the installation of Roots blower, the equipment foundation is very important. The basic equipment is firm and good, and the equipment can be successfully installed in the later stage to reduce the incidence of equipment failure. At the same time, the solid basic equipment can transport the power and vibration power generated by the operation of the equipment to the soil, and the effective resonance: if the equipment foundation has a problem, it will affect the normal operation of the equipment, seriously cause the displacement or overturn of the equipment, and directly affect the service life of the mechanical and electrical equipment. Therefore, it is necessary to pay attention to the basic problems of the equipment to provide protection for the later installation and adjustment of the mechanical equipment.

1.2 Screw Connection

In general, in the installation of Roots blowers, bolt and nut holes must be set in advance. In the installation process of Roots blower, position error exists objectively, such as the position of the reserved hole is not compliant, or the position error of the embedded bolt is large. Over time, small differences will affect the later installation of Roots blowers, and then the equipment installation can not be smoothly carried out. If the connection is too large, it will be affected by the electromagnetic force and mechanical force for a long time, resulting in the bolt machinery, resulting in the loosening of the connection between the bolt and the nut, and the nut sliding or damage. In this case, the device fails due to loose connections.

1.3 Device Vibration

The installation of Roots blowers is characteristic and takes a long time in operation and use. In addition, the mechanical vibration is relatively large, shortening the service life of the equipment and improving the maintenance and adjustment rate in the later period. The main common problem is that the shell and rotor are the same. Poor centroid, friction between stator and rotor problems, bearing clearance is too large or rotor misalignment. The common problems of motors are: rotor and stator problems uneven magnetic density, mutual friction and rotor misalignment. In the operation of electromechanical pump, the actual participation of the rated standard parameters are different, and the pump operation is unstable. In this case, the operator cannot operate the pump under the specified parameters.

1.4 Excessive current

During the installation and use of electricity for Roots blower, there are current problems, among which the overcurrent problem is more common. The main reasons are: the motor power is too large, the transmission line resistance is high, and the power phase is insufficient. The causes of overcurrent in the pump include three aspects. Rotor and housing friction, clothing into the pump housing, bearing damage. It must be noted that the equipment itself may cause these current problems, but during the operation process, personnel operation is not compliant, will also cause overcurrent problems, affect the later installation, and bury more risks for the installation of mechanical and electrical equipment.

2.1 Roots fan sequence optimization

With the progress of The Times, the installation technology and methods of Roots blower are changing with each passing day, the installation method is different, its advantages and disadvantages and applicable places are different, the installation order is different, the installation effect is slightly different, and the installation efficiency is different. When the Roots blower is installed, the power generation device is used to obtain power and power to promote the operation of the equipment and install the equipment smoothly. Before the installation of Roots blower, equipment and facilities should be fully configured and the installation sequence of various equipment should be reasonably set. Changing, adjusting and chemical equipment installation sequence is not simply adjusting the original installation sequence. According to the specific situation of civil engineering, adhere to the concept of scientific application, economic feasibility and cost reduction, reasonable planning and arrangement of equipment installation sequence. For example, the installation of derrick, winch, pressure fan, substation and other facilities should be arranged scientifically. On this basis, we should make a reasonable installation plan, analyze the economic feasibility of each plan, and determine the plan. Improve the installation sequence of equipment, shorten the construction period, improve the installation efficiency and rationality of equipment, and effectively reduce the incidence of hidden dangers of equipment installation.

2. Install mechanical devices in strict accordance with the process

For Roots blowers, the procedures and steps are established, effectively regulate and constrain the installation of equipment, effectively complete the installation of equipment, and ensure that the installation quality of equipment meets the standard. At the same time, according to a large number of practices, the installation of mechanical equipment is not strict, which is an important reason for the installation of hidden dangers. After the installation of Roots blower, if various risks are needed to improve the quality and accuracy of the installation project, it is an inevitable trend to install mechanical equipment in accordance with the setting procedures and steps. Therefore, as a project manager and construction enterprise, it is necessary to strictly monitor the installation operation process and behavior of personnel. During the installation of equipment, installation personnel should install equipment in strict accordance with the setting procedures and requirements. Device installation changes or exceeds installation steps at will. In addition, in order to improve the comprehensive quality and practical ability of installation personnel, construction enterprises should increase the technical and on-the-job training of installation personnel, so that installation personnel can be deeply familiar with the content and process of equipment installation, and provide guarantee for the standardized installation process.

2.3. Adjust the operation of Roots fan after installation

In the installation of Roots blower, adjustment operation is a link, designed to test whether the equipment can operate normally, whether the basic parameters are consistent with the actual situation, check the operating efficiency of the equipment and the overall coordination of the project, to ensure the effective operation of the equipment after formal operation. During device installation, the installation function of the device and related prisoners must be fully considered according to different installation requirements, sites and users, and the type and number of devices to be installed. The commissioning scheme must be properly adjusted according to the device type, and the device steps and methods must be clearly specified. According to the debugging plan, trial run and adjust the equipment at the installation point to check whether the operation of the equipment is abnormal and whether the parameters and facilities meet the design requirements. If this happens, timely analysis of the reasons, take effective measures to solve the problem, to get the expected adjustment results.

2. Ensure the improvement of the comprehensive quality of mechanical and electrical personnel

To a certain extent, the comprehensive quality of mechanical and electrical personnel has a great impact on the installation quality of equipment, so it is necessary to improve the comprehensive quality of installation personnel. (1) Organize the training of installation personnel, including installation technology, content and standards. (2) Strictly guide the installation personnel to operate the equipment installation according to the process, and implement the equipment power supply and distribution regulations. (3) Check the power circuit regularly and adopt the solution in time. (4) Effectively remind the mechanical equipment to ensure normal operation of the equipment.

In short, in the installation of Roots blower, it is necessary to follow the performance of the equipment and install it in strict accordance with the operating instructions. Operators should also check the hidden dangers of Roots blower every day, early detection and treatment, so as not to affect the normal use of equipment.
