Industrial fans weighing from 500 kilograms are used in manufacturing, industrial and agricultural enterprises. The main purpose of the fan, which is a system of units, is the supply, transportation, processing and removal of air from the premises through special channels. A household fan can not do at the enterprises of chemical industries, where waste is thrown into the air. Installation of an industrial fan in smokestacks will ensure the maximum permissible content of pollutants in the ambient air, competent fire safety.
Work on the delivery, installation, connection and subsequent commissioning of an industrial fan is time-consuming and requires appropriate experience. Sintez TMK has the necessary resources and a qualified staff that can cope with these difficult tasks.
Installation of industrial fans of large dimensions in the room occurs with the help of winches, forklifts or cranes. The mechanical component must be installed on a flat horizontal surface, and the free space around the fan itself will facilitate its operation.The main difference between domestic and industrial fans is size, weight and power. Devices used in production weigh in the aisles of 100-1000 kilograms, and some reach ten tons. Accordingly, they have a more complex design, so the preparatory work for the installation of an industrial fan should be entrusted to professionals. The same applies to the maintenance of an industrial fan, which must be carried out by qualified personnel using modern equipment. Specialists provide regular maintenance according to the schedule, if necessary, carry out scheduled repairs of the industrial fan. Sintez TMK has many years of experience in performing such tasks and is ready to assume these obligations, taking into account the recommendations of the manufacturer of the ventilation system.
Installation and connection of industrial fans
The sequence of works on installation of industrial fans of large dimensions can be divided into the following stages:
- Preparation of the Work Project for the installation of an industrial fan, which must meet all established standards. This document determines the technical sequence of works, places in which ventilation equipment is stored, instructions for loading and unloading and rigging, instructions for fire and environmental safety, installation technology, etc.
- Installation of the mechanical component. This includes work on the organization of appropriate engineering systems and structures, preparation of a place to place a fan. At this stage of installation of the industrial fan is connected to the duct system. Particular attention is paid to the arrangement of openings for the installation of industrial fans.
- Installation of electrical systems. These works involve the installation of electrical connections, the introduction of cables into the electric control shield, the connection of control sensors, and other actions aimed at ensuring the continuous operation of the air ventilation system.
- Test and start-up. It is necessary to check the efficiency of the electric motor and the serviceability of the elements that, by their rotation, introduce or remove air from the room. In addition, the technical characteristics declared in the passport of the device, such as air flow, pressure, rotation and energy consumption, are checked.
Types and features of industrial fans
The mounting of the fan, the way the equipment is connected to the duct and the place for installation is directly related to the type of system and for what purposes it is used. Roof fans are placed on the roofs of buildings, and axial fans are installed in basements, tunnels, mines or garages. On the roofs are also installed systems aimed at smoke removal, channel fans, exhaust systems. Dismantling large-diameter industrial fans and installed on the roof or facade of a building requires special knowledge and equipment.
Dust fans are designed to remove wood dust, grain waste, wool, cotton and other small-structured elements from the premises. Thrust units provide the supply of air masses into the boiler furnace and the subsequent withdrawal of combustion products from it. To reduce the vibration emanating from the working fan can be special vibration insulators and flexible inserts.
Ventilation systems generating pressure with an index of 1 kPa, Z kPa and up to 12 kPa have been developed, which respectively belong to low, medium and high pressure units. The manufacturers of such industrial equipment pay special attention to the temperatures and conditions in which the ventilation system operates. Household fans work with air and gas reaching 80 ° C, and heat-resistant can withstand up to 200 ° C.
Engineers will provide the customer with the necessary documents and permission to conduct this activity, develop an RRP for the installation of an industrial fan. Sintez TMK offers a full range of services from the rigging of an industrial fan to its full connection and subsequent maintenance.
The company for many years performs installation and various specialized work in the construction of modern industrial facilities. During this time, the company’s specialists have gained extensive experience and developed their own integrated approach to solving complex problems.
This will avoid common errors and eliminate the risks of improper selection of ventilation systems, components, materials, Errors in air-heat balance calculations, etc. Competent installation of a large diameter fan with Synthesis TMK company will ensure the reliability and reliability of the system, will retain the warranty issued by the manufacturer of the unit.
In addition, it is important to carry out maintenance and diagnostics of industrial ventilation, the recommendations for which are recorded in the technical passport.
