The installation of screw compressor room equipment directly affects the performance and operation stability of the equipment. Therefore, mastering the key points of installation of mechanical and electrical equipment for screw air compressor is particularly important.
Selection of installation site
Most of the time, the staff will ignore it. screw compressor The selection of the screw compressor results in unstable performance. We should attach importance to the choice of installation location and make specific plans. The possible problems should be contained in the bud stage to ensure the effective and stable operation of screw air compressors.
The installation location of screw air compressor should be selected in a wide and well lit area, so that the installation and maintenance of the body and the implementation of maintenance work can be carried out. Screw air compressor installation needs to choose relatively dry, better air circulation and less dust, so that the service life of the equipment can be prolonged. If the factory environment is poor and the dust is more, proper pre filter equipment should be installed to protect it. In terms of environmental temperature, it should not be too high. Generally, it should be installed below 40 degrees Celsius. Too high temperature will build the air volume during the operation of the equipment, so that the efficiency of the equipment will be reduced to a certain extent.
At the same time, we need to reserve the access before installation. If conditions permit, the overhead crane can also be set up, which will provide greater convenience for future maintenance work. Generally speaking, there should be at least 70 centimeters of distance between the compressor and the wall as the reserved space for maintenance. The distance between the air compressor and the top space can not be less than one meter.
In addition, the installation of air cooling units and water-cooling locations should be reserved, and the cooling hot air can be excluded to outdoor through the installation of air guide pipes. The inlet and outlet of the water cooling units must be equipped with valves. If there is any impurity in the cooling water, it is necessary to install the filter equipment ahead of time.
Installation of piping system, fixed foundation and cooling system
Piping system. When installing the piping for the main road, the pipeline should have a slight inclination angle to facilitate the flow of condensate fluid in the pipeline. Use large diameter pipes as far as possible to ease the resistance of pipelines and improve their working efficiency. The feeder pipe should be connected from the top of the main road to prevent the condensate from flowing back into the machine to cause operational failure. During installation, attention should be paid to maintaining the fixed size of the main road, not changing the sequence at random, avoiding mixed flow phenomenon at the joint, and losing pressure to affect the service life of the equipment. Proper installation of dryer and other buffer cleaning equipment can lighten the load of the machine.
Generally speaking, the pressure of the system needs to be controlled below 1.5. If the instantaneous gas consumption of the system is relatively large, it can be alleviated by choosing a large gas storage tank. In addition, in the process of pipe installation, the use of elbow or various valves can be reduced as far as possible. Such components can easily cause the loss of equipment pressure, which will reduce the efficiency of equipment to a certain extent.
Fixed foundation. The foundation system needs to choose a more rigid floor to build and install. Before installation, the staff need to calibrate the reference plane to prevent excessive noise due to the vibration after the equipment starts. If the location of the air compressor installation is located in the non bottom position, the staff and equipment must be well handled to prevent vibration and noise and other safety hazards. Generally speaking, the vibration amplitude of screw air compressor is not large during operation, so it is not necessary to add a fixed foundation. But the premise is that the installation site of the air compressor must be leveled. At the same time, it should not be soft soil below. In order to make the operation of the equipment more efficient and minimize the impact of the working conditions on the environment, it is possible to pre pave the cushion with 5 to 10 millimeters thick on the ground or to the shockproof cushion when the screw air compressor is installed.
Cooling system. When selecting air-cooled compressors, ventilation conditions should be taken into account. Avoid installing the air compressor on the side of the high temperature equipment. If the air compressor is running, if inhaling a lot of high temperature gas, the exhaust temperature will be too high, so that the equipment can not operate normally. If the size of the installation space is subject to certain restrictions, it is necessary to install the exhaust equipment properly so as to ensure the circulation speed of the air.
