What are the operating conditions for explosion-proof Roots blowers? 1. The inlet air temperature of the conveyed medium generally should not exceed 40°C. 2. The particle concentration in the medium should not exceed 100 mg/m³, and the particle size should not exceed half of the minimum working clearance.
Explosion-proof Roots blower What are the operating conditions?
1. The inlet air temperature of the conveyor medium generally should not exceed 40°C.
2. The particle concentration in the medium must not exceed 100 mg/m³, and the particle size must not exceed half of the smallest working gap.
3. Explosion-proof Roots blower During operation, the bearing temperature must not exceed 95°C, and the lubricating oil temperature must not exceed 65°C.
4. The operating pressure must not exceed the pressure increase range specified on the nameplate.
5, Explosion-proof Roots blower The clearances between the impeller and the casing, between the impeller and the side plates, and between impellers have already been adjusted at the factory; when reassembling, be sure to maintain these clearances.
6. When the Roots blower is running, the oil levels in both the main oil tank and the auxiliary oil tank should be between the two red lines on the oil level gauge.
7. Check whether there are any unfastened connections at the inlet and outlet ports, and ensure that all support points for the pipelines are fully installed. For fans and vacuum pumps requiring cooling water, make sure that the cooling-water installation meets the specified requirements.
Because Explosion-proof Roots blower Since it is a high-speed rotating machine, it generates vibration. The pulsation of the internal air can exacerbate the vibration of the Roots blower; therefore, when installing the Roots blower, it must be securely fixed to the ground. Depending on the blower model and its dimensions, excavate a square pit measuring 150 mm × 150 mm and 300 mm deep at the appropriate location. Install floor bolts into the pit, connect the blower using bolts and nuts, and then fill the square pit with cement concrete.
How do you commission an explosion-proof Roots blower?
1. Check the tightness of all components and for any looseness in the locating pins.
2. There is no oil leakage inside the blower body.
3. Explosion-proof Roots blower There should be no dirt, rust, or flaking inside the body.
4. Ensure that the lubrication and cooling conditions are normal. Pay attention to the quality of the lubricating oil, listen carefully for any unusual noises during the blower’s operation, and be mindful of the equipment operating under conditions that do not meet specified requirements. Regularly add grease.
5, Explosion-proof Roots blower Overload may not always manifest immediately, so pay close attention to trends in water inflow, exhaust pressure, bearing temperature, and motor current to ensure the machine is operating normally.
6. Before disassembling the machine, measure all mating dimensions, keep a record, and mark the parts to ensure that the original fit requirements are maintained after assembly.
7. After installing a new machine or performing a major overhaul, clean the blower and oil tank. Start operation according to the usage stage; it is recommended to replace all lubricating oils after 8 hours of operation.
8. Maintenance recommendations: Develop a reasonable maintenance schedule based on specific usage conditions, carry out maintenance on time, keep detailed records, and conduct a major overhaul annually, replacing bearings and any damaged components.
9. Explosion-proof Roots blower Major repairs are recommended to be performed by professional maintenance personnel.
