Working principle
Stainless steel food grade high-temperature clamp negative pressure pumps typically operate based on centrifugal or volumetric principles:
Principle of centrifugal pump:
By generating centrifugal force through the rotation of the impeller, liquid is drawn from low to high and discharged through the outlet.
High temperature exhaust design can effectively solve the problem of cavitation and ensure the stable operation of the pump under high temperature conditions.
Principle of positive displacement pump:
Like gear pumps or screw pumps, liquid suction and discharge are achieved through volume changes. The rotation of gears or screws causes a change in the volume of the cavity between the teeth or the screw groove, thereby generating negative pressure to suck in liquid and discharge it after compression
| Product characteristics
Food grade material:
The liquid receiving parts of the pump are usually made of food grade materials such as 316L stainless steel and PPS plastic, with polished surfaces that comply with FDA, WRAS and other certifications to ensure no pollution.
The sealing components are made of food grade rubber such as silicone, EPDM, or NBR to ensure safety and reliability in high temperature and food grade applications.
High temperature resistant design:
The material and structure of the pump body can withstand high-temperature media such as hot water, syrup, etc., with a maximum working temperature of up to 150 ℃.
Efficient and low-noise:
Adopting brushless DC motor, it has high operating efficiency and low noise (≤ 35dB (A)), suitable for use in food processing environments.
Sanitary design:
There are no dead corners inside the pump, making it easy to clean and disinfect. It supports on-site cleaning (CIP) and on-site disinfection (SIP), meeting hygiene standards.
Multiple configurations:
Provide multiple voltage and power options, customizable with PWM speed control, FG signal lines, and other functions to meet the needs of different devices
|Maintenance of Stainless Steel Vacuum Pump
Routine maintenance
Check the oil level and quality: Ensure that the oil level is in the middle of the oil gauge, the oil quality is clean and free of impurities. If the oil deteriorates or the oil level is insufficient, it should be replaced or replenished in a timely manner.
Clean the filter screen and filter element: Regularly clean or replace the filter screen and filter element to prevent impurities from accumulating and affecting the pumping efficiency.
Monitor abnormal noise: Pay attention to monitoring the noise of the pump during operation. If there is any abnormality, check the internal parts for wear or looseness in a timely manner.
Check seals: Regularly inspect seals (such as O-rings, gaskets) for aging or damage to ensure good sealing performance.
Regular maintenance
Replace oil seals and seals: It is recommended to check and replace oil seals and seals every 6 months to 1 year to prevent leakage.
Cleaning pump chamber: Clean the pump chamber, oil tank and other components every 6 months or after running for 500-2000 hours.
Check the lubrication system: Ensure that the lubricant is sufficient and of the correct type to avoid component wear caused by insufficient lubrication.
Check the cooling system: Ensure that the flow rate and temperature of the cooling water or cooling air meet the requirements to prevent overheating of the pump body.
Professional maintenance
Overhaul and calibration: It is recommended to have professional personnel perform disassembly and calibration to avoid affecting the performance of the pump due to improper operation.
Comprehensive inspection: Regularly conduct a comprehensive inspection of the pump, including the wear of vulnerable parts such as bearings, seals, and exhaust valves.
Safety and Storage
Power off operation: Before maintenance, ensure that the pump is powered off and connected to atmospheric pressure to avoid accidental start-up.
Long term idle: If the pump needs to be idle for a long time, it is recommended to disassemble and properly store important components, and conduct regular inspections to prevent rusting
