In recent days, customers have complained about high-pressure blowers , and more than 90% of them are caused by improper maintenance and maintenance of the customers. Therefore, we should not let our staff know about the maintenance of high-pressure blowers. ! Here I repeat the maintenance and repair of the high pressure blower. In fact, we have to protect the high-pressure blower in two aspects: first, pressure, and second, dust. (1) The fan does not rotate 1, not connected to the power - turn on the power 2, the motor does not work - check the motor wiring or replace the motor 3, the fan head is damaged - repair the fan or replace 4, foreign matter stuck in the fan - remove foreign objects (2) Increased noise 1, bearing dry lubrication - plus bearing grease 2, bearing damage - replacement of bearings 3, impeller wear - replace the impeller or pump head 4, the solid parts loose or fall off - tighten the fasteners 5. There is foreign matter in the high pressure blower - remove foreign matter or replace the pump head (3) Increased vibration 1, bearing damage - replacement of bearings 2, the impeller is unbalanced - remove the foreign object in the impeller or static balance 3, spindle deformation - replace the spindle or pump head 4, the working state enters the quake zone - adjust the working state, avoid the quake zone 5, the inlet and outlet ports into the filter blockage - cleaning filter (4) Increase in temperature 1. The inlet temperature is too high - lower the inlet temperature 2, bearing dry lubrication - plus bearing grease 3. Reduced efficiency of high pressure blower - remove leaf dust or replace pump head 4, work status changes - adjust the working status 5, the ambient temperature increases - increase the environment ventilation (5) Pressure reduction 1. The pump head speed is reduced - the power supply voltage is low or the motor is faulty. 2, pipe network resistance increased - reduce pipe network resistance 3, work status changes - adjust the working status 4, motor steering reverse - motor rewiring (6) Flow reduction 1. Import and export gas filter plugging - cleaning filter 2. The pump head speed is reduced - the power supply voltage is low or the motor is faulty. 3, pipe network resistance increased - reduce pipe network resistance 4, work status increases - adjust the work status 5, motor steering reverse - motor rewiring
For pressure, the pressure relief valve is often used. It is an unloading valve. When the pressure of the high pressure blower exceeds the pressure set by the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure. Protect the high pressure blower.
For dust, filters are often used. It is based on different use sites, often using different filter precision filter cartridges, different filter cartridges have different maintenance methods and service life, you need to ask when ordering.
In some special occasions, special protection is needed: for example, when using in a sealed environment, pay attention to ventilation and heat dissipation; when the ambient temperature (the intake air temperature is relatively high), pay more attention to ventilation and heat dissipation, or choose to allow air intake. High-temperature high-pressure blower (current domestic high-pressure blower allows a maximum inlet air temperature of 200 degrees);
