The vacuum systems in the mining and construction industries are long-term exposed to environments with high dust, high humidity, and heavy-duty continuous operation. Traditional oil-lubricated vacuum pumps are prone to wear and oil circuit blockage after dust intrusion, resulting in frequent maintenance and high downtime costs. Targeting harsh working conditions, Leynow has launched combination solutions of water ring vacuum pumps, Roots vacuum units, and oil-free vacuum pumps, providing a stable and reliable vacuum acquisition method for mining and construction processes ranging from gas drainage and slurry dewatering to pneumatic conveying and foundation treatment.
Challenges Faced by the Industry
The vacuum systems at mining and construction sites face not only the question of "whether it can pump", but more importantly, wear resistance, dust resistance, and continuous stability. In actual projects, customers often encounter the following types of problems:
Dust Intrusion and Wear
High dust concentration in mining crushing, screening, and conveying processes. After dust enters the pump chamber, it accelerates the wear of the rotor and seals, shortening equipment lifespan.
Heavy-duty Continuous Operation
Processes such as gas drainage and slurry filtration require equipment to operate continuously for 24 hours. Pump body overheating and vacuum degree attenuation will directly affect the production pace.
High Pumping Speed and Vacuum Fluctuations
Drainage and filtration processes require continuous high pumping speeds. Vacuum degree fluctuations when pipeline network resistance changes will reduce filtration efficiency and drainage effects.
Maintenance Costs and Downtime Losses
The on-site environment is remote, and spare parts supply and maintenance response are slow. A single unplanned downtime may cause the entire production line to stagnate.
Leynow Mining and Construction Industry Solutions
Targeting the actual working conditions of mines and construction sites, Leynow provides overall vacuum solutions centered on water ring vacuum pumps and Roots vacuum units, forming a complete service closed loop from equipment selection and pipeline design to post-maintenance.
Dust-resistant and Harsh Condition-resistant Design
Water ring vacuum pumps use water as the working fluid and can withstand dust-containing gases and condensable gases. The gap between the impeller and pump body is reasonably designed to reduce dust wear; dust removal and filtration devices can be optionally configured at the front end to further protect the pump body.
Selection Solutions Matched to Working Conditions
Based on pumping volume, vacuum degree range, medium temperature, and dust content, professional engineers provide combination selection of water ring pumps, Roots pumps, or vacuum units, avoiding "using a large pump for a small job" or overload operation.
Guarantee of Stable and Continuous Operation
For long-term continuous operation scenarios such as gas drainage and slurry filtration, the impeller structure and working fluid circulation system are optimized to reduce the risk of pump body overheating and maintain stable vacuum degree output.
Full-cycle Service and Parts Guarantee
Providing installation and commissioning, regular follow-up visits, and maintenance contract services. Repair parts are Leynow original genuine parts. All repair projects come with a 12-month warranty to reduce unplanned downtime.
