GXS160 Edward screw vacuum pump maintenance: Clearly mark the position, length, and size of the screws to avoid assembly errors. The accessories must be neatly arranged for subsequent assembly
Product Details
Dongguan Biqier is a professional vacuum pump maintenance service provider. Edwards' spiral rotor design provides pumping speed, which is part of an excellent thermal management system that can greatly improve pump performance and the service life of seals, bearings, and motors, ensuring that the pump has a long service life. Widely applicable to various applications, GXS pumps can be provided separately or together with high-speed Roots booster pumps to increase their capacity and ultimate vacuum. In addition, Edwards also offers a range of purge options, filters, collection tanks, inlet isolation valves, and silencers. These components, along with our specialized high flow purge and solvent flushing accessories, can keep the interior of the pump clean without the need for disassembly and cleaning.
Maintenance warranty and long service life:
Long service life non oxidizing transmission oil can extend maintenance intervals to 5 years. The quick connect device interface can accelerate the installation and replacement speed of pumps, thereby improving the normal operation time of factories. The customized high-efficiency motor and drive system using excellent sealing technology greatly reduces power consumption. The minimal demand for cooling water and purge gas, combined with improved powertrain technology, enables long maintenance intervals and almost maintenance free operation.
Low impact on workplace and environment:
The GXS pump has incredible compactness. Even without the use of a muffler, Edwards' excellent spiral rotor design can achieve extremely quiet and low vibration operation.
Easy installation and operation:
The GXS pump can be easily rolled into place by wheels or lifted into place by a forklift. With the provided matching joints, it can be connected to process and maintenance equipment with just one button press to operate.
Suitable for integration into larger systems:
Under standard conditions, GXS pumps and their combinations come with serial (RS232) communication and LAN based network service capabilities. Provide optional modules to increase parallel (digital I/O) and Profibus control functionality.
After repairing the vacuum pump:
Edwards has skilled application experts who will provide recommendations on the appropriate configuration for your process or application.
Widely used: solar energy, silicon crystal growth, lithium-ion battery manufacturing, freeze-drying, pharmaceuticals, food processing, disinfection plasma, winding coating, optical lens coating, architectural glass coating, metallurgy, heat treatment, casting, sintering, leak detection, food packaging, vacuum chamber evacuation, high-purity gas cylinder filling.
GXS160 Edward screw vacuum pump maintenanceMethod:
1、 Preparation before maintenance
Appearance inspection: Check whether the pump body is damaged. If there is any damage, record it and inform the user unit
Understand the working conditions: confirm the type of process used to determine the subsequent handling method
Fault diagnosis: Check if it is stuck - the relevant parts can be removed and tested by turning with a wrench. If it can be turned, it is not stuck; If it gets stuck, it should not be powered on to avoid burning the motor
Power confirmation: Confirm the voltage parameters based on the actual voltage of the unit being used
Waterway inspection: Water must be supplied before powering on, and all joints must be checked for water leakage
2、 Disassembly and maintenance steps
Disassembly precautions
Special tools must be used for disassembly, otherwise it cannot be completed
Clearly identify the location, length, and size of the screws, mark them properly, and avoid errors during assembly
Accessories must be neatly arranged for easy assembly in the future
Key component inspection and repair
| component | Inspection content | repair method |
| screw/Rotor |
Check for wear marks and measure rotor clearance | Minor wear is repaired by laser cladding, usingAlloy powder; Severe deformation requires returning to the factory for dynamic balance correction |
| bearing | Check the operation and vibration spectrum600-800Hz peak indicates early fatigue | The original deep groove ball bearing can be upgraded to an angular contact bearingReplace the lubricating grease with fully synthetic high-temperature type |
| mechanical seal | Average service lifeAfter 8000 hours, the leakage rate increased by 37% | Replace according to the seven step method: relieve pressure→ Oil discharge → Disassembly → Cleaning → Installation → Debugging → Acceptance |
| bushing | Check the gap, standard gap0.08-0.12mm | If the wear exceeds the limit, tungsten carbide coating can be sprayed to restore the size, and the hardness needs to reachHRC60 or above |
| gear | Check for wear and tear | Adjust the gear backlash synchronously during assembly to0.08-0.12mm |
Cleaning treatment
Use an ultrasonic cleaning machine to clean all parts
After cleaning, put it in the oven and bake it dry
Perform sandblasting treatment on the cavity and cover plate
3、 Assembly and Debugging
Assembly points
Bearings and shaft seals: must be assembled in place, otherwise it will affect maintenance quality and service life
Accessory quality: Use accessories that meet or exceed OEM specifications
Gap debugging: This is the key to determining the service life and vacuum degree of the vacuum pump
Screw locking: Lock according to standard torque to prevent loosening and jamming during use
Dynamic balance requirements
After the overhaul of the rotor assembly, the residual unbalance in the dynamic balance test should be less than 0.5g · mm/kg
The repair of the mating surface adopts laser cladding technology, with a coating thickness of 0.1-0.2mm
4、 Common faults and maintenance methods
| fault phenomenon | Possible reasons | Repair Method |
| Decrease in ultimate vacuum degree | Sealing failure, oil contamination, rotor wear | Use a helium mass spectrometer to detect leakage points and replace seals; Replace the oil filter; Use an endoscope to detect the rotor clearance and repair or replace it if necessary |
| abnormal vibration | Insufficient pre tightening force of foundation boltsAging of buffer rubber pad, early fatigue of bearings, poor alignment of couplings | Check the pre tightening force of foundation bolts; Replace the buffer rubber padUse a vibration spectrum analyzer for diagnosis; Use a laser calibrator to center and control the radial deviation of the coupling within 0.02mm |
| The temperature is too high (exceeding85℃） | Cooling system malfunction, overload operation, insufficient lubrication, blocked heat dissipation fins | ① Check the temperature difference between the inlet and outlet of the oil cooler, clean the heat dissipation fins, verify that the oil level is at 2/3 of the window, and check the balance of the three-phase current of the motor |
| Difficulty initiating/Stuck up | Motor malfunction, mechanical jamming, foreign object ingress | Check the power supply and motor winding; Check and clean up foreign objects or damaged parts inside the pump |
| seal failure | Mechanical seal aging | Observe whether there are any abnormal oil stains at the oil mist discharge outlet of the pump body, use a helium mass spectrometer to detect the leakage point, and replace the seal |
5、 Test acceptance
Motor testing: After confirming the voltage is correct, power on and test the forward and reverse rotation of the motor
Vacuum test: Connect the vacuum gauge head and check whether the maximum vacuum degree and pumping speed meet the standards
Leakage test: The leakage rate meets the acceptance criteria
Running test: Conduct 24-48 hour continuous testing after water and air supply to monitor total pressure, temperature, vibration, and noise levels
Vibration analysis: Use professional equipment for vibration analysis to ensure smooth operation
6、 Maintenance suggestions
Maintenance interval: GXS160 uses long-life non oxidizing transmission oil, and the maintenance interval can be extended to 5 years
Regular inspection: Regularly check the lubrication of bearings and replace damaged bearings in a timely manner
Cleaning and maintenance: Regularly clean the surface and interior of the pump to avoid the accumulation of impurities; Clean the heat dissipation fins at least twice a month (in dusty environments)
Oil filter replacement: Regularly replace the oil filter to avoid fluctuations in vacuum degree
Electrical inspection: Regularly check the electrical connections
