Laboratory centrifuge operating instructions for operation, structure, performance, precautions, installation, operation, maintenance and maintenance, failure analysis and troubleshooting methods,
Geonet can be used as a kind of filling layers for stabilization, detritus separation, horizontal drainage cushion, underwater drainage constructure and slope road protection structure in building roads, railway, ports, airports, mining, hydro-power engineering projects.
Chief specifications include CE121.CE131.CE151.CE181.DN1.HF10
1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ;
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction .
3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;
4. It is used in soft soil base reinforcement treatment , is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base;
5. It is sued for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.
The laboratory centrifuge operating instructions consist of working principle, structure, performance, precautions, installation, operation, maintenance and maintenance, failure analysis and troubleshooting methods, quality assurance and service commitment.
First, the working principle: laboratory centrifuge (hereinafter referred to as centrifuge) is a kind of machine that mainly performs solid-liquid or liquid-liquid separation under the action of centrifugal force.
Second, the structure: consists of the frame, rotor, drive system, refrigeration system, control system and safety protection system.
Third, the performance:
1. Microcomputer control.
2, the use of AC variable frequency motor, imported compressor unit and control valve, fluorine-free refrigerant.
3, with a soft brake function.
4. It has the rotor number recognition function.
5. It has over-temperature, over-speed, unbalance and door cover safety protection functions, and displays fault information and audible alarms in the display window.
Fourth, note:
1. Before using the centrifuge, check whether the external power supply meets the requirements and whether the centrifuge is reliably grounded.
2. Before using the centrifuge, carefully check the rotor and the centrifuge tube for cracks or corrosion. It is strictly forbidden to use a rotor or a centrifuge tube with cracks or corrosion.
3. It is forbidden to operate the rotor beyond its rated speed.
4. It is strictly forbidden to operate unbalancedly.
5. It is strictly forbidden to run at high speed without rotor.
5. Installation: Install the main engine and rotor as required.
Sixth, operation: including the steps of starting up, placing separated samples and controlling the panel operation.
VII. Maintenance and maintenance: including maintenance and maintenance of the main engine and rotor, anti-pollution measures, disinfection and sterilization.
Eight, fault analysis and troubleshooting methods: including security protection faults and common faults analysis and elimination.
Nine, quality assurance and service commitment: 1 year warranty, 48 hours response.
