Installation and commissioning
Air-delivery devices are often made from more than a variety of mechanical parts and components of the transportation system, the installation of a larger workload, the installation process is also more complex, involving lifting, fitter, plumbing, electrical, and other types of work. The quality of the installation quality is often determined the whole device can be used normally should be adequate attention. The delivery of large-pressure pneumatic conveying equipment, often at the same time the need to install a dedicated compressor armed.
1. Send-pressure pneumatic conveying equipment to install the main points
First of all, construction should check the information, including the depth of the pit, a high platform, set aside hole size and so on; followed should be based on the use of equipment and manuals to comply with "equipment installation and inspection of construction norms," the provisions of the relevant equipment in place to adjust the level and degree After the degree of vertical fastening. Pipeline should be installed to ensure that no dislocation junction, between the flange gasket, and other out-free, compressed air pipe installed before the wall should be carried out to deal with rust, all piping connections should be tight. Finally, connect the power control equipment, control access to and control of pipeline routes.

Operation of the main points
As the pneumatic conveying equipment and a large variety of different principles, its operating requirements vary, it is difficult to elaborate, the Senate can often Goldman's value for all kinds of pneumatic conveying equipment Manual. Following is only part of a common brief.
1. Send-pressure pneumatic conveying equipment to operate the main points
The cease armed compressor, supervision and operation, lubrication and so on are required to operate according to the manufacturer's specification for use. Sent to the pressure-pneumatic conveying their own devices to operate more or less the main points are as follows:
1) must put a net oil and water separator and Zhu Qiguan accumulated in the oil and water, this water in the transmission of greater sensitivity of the material should pay special attention to. ……Click here to regist or click here contact us.
2. Suction-send pneumatic conveying equipment to operate the main points
Sending smoke-pneumatic conveying equipment to food absorption, ship unloader, to send a vacuum suction, suction-type containers for the transportation representative of the operation, the following should be noted:
1) Air machinery must under no-load start-up to prevent the motor burn. ……Click here to regist or click here contact us.
Fault and its countermeasures
Pneumatic conveying in the sealed in a gas pipeline as a carrier for the transmission of materials or small items. As the materials to produce movement relative to the pipeline and therefore have a pipeline of wear and tear is inevitable. In certain cases, have also impeded the movement of materials, which may have a plug. With the properties of materials, the situation of the pipeline, the source of gas as well as the mechanical operation of the operation and even the weather changes are possible to plug material, particularly in confined conditions, these changes are not always easy to detect, so if there is blockage often sudden, often Will be taken by surprise, have a significant impact on production.
1. Blockage
(1) plug: For a reasonable design parameters, installation of manufacturing precision, and the correct operation of pneumatic conveying systems, in certain cases, by chance, would have expected to lose control plug. This happens in the following areas should seek to plug the cause.

(2) to prevent the blockage of the method
1) in the design of pneumatic conveying equipment must be in accordance with the delivery of materials performance, productivity, transmission distance and so on the actual situation, a reasonable choice of pneumatic conveying the type of device
And other parts of the structure, and reasonable under the circumstances to determine the parameters of the device.

2. Wear
In the pneumatic conveying equipment, materials (or thing) compared with the loser expected to have a mobile control, is expected to lose control of wear and tear is almost completely unable to prevent. Actual production
Often take various measures to reduce the wear and tear to find the best way of transportation.

(1) of the pipe, the main way to increase the service life of three.
1) to change the pipe material, to improve wear resistance, wear suitable materials can bend their life expectancy increased by 10 times.

(2) reduce the pipe to increase wear and tear of life measures:
1) as far as possible to reduce the speed of air transport. Pressure on the gas-delivery device conveying the best use of low-speed low-voltage transmission; sent to the suction-type device Pneumatic Conveying the best use of high-vacuum low-speed transmission.

Pipeline wear a lot of determination, can be used vernier caliper measurements before and after delivery wall thickness of the poor can also weighing section of pipe before and after weight difference, ultrasound thickness can be measured directly before and after the wear and tear of the thickness of the wall.
Maintenance and repair work
Pneumatic conveying equipment used in producing the smooth, with the exception of the design, manufacture, installation and operation of all parties have to be very serious, day-to-day maintenance of the preservation is also very important. In particular, pneumatic conveying equipment are sealed in the state, not easy to find a lot of hidden fault, which appears to be a more timely repair and maintenance.
Air-delivery devices generally can be divided into: air machinery, air duct, Feeder, is expected to lose control, Cha Dao, separation, discharge, dust control, dust control system and electronic control systems, in part. The various parts of the maintenance of the main points as follows:

3. Feeder points due to the maintenance of the feeder with a wide variety of structures, this is difficult to list their maintenance and maintenance of the main points of commonality is only a brief description of the problem are as follows:
1) there is any part of the rotation, such as the wheel when the valve leaves feed tube, screw feeder, and so on, must wear regular checks to ensure good sealing performance; damage to the bearings need to be replaced in a timely manner to ensure good lubrication, making rotation Light and flexible.
