First, the elliptical gear does not rotate: 1, there are debris in the pipeline;
Lift Platform is a kind of mufti-functional Lifting Equipment . It usually divided into Fixed Lift Platform , Stationary Lift Platform, Mobile Lift Platform, chain guide rail cargo lift platform, arm lifts, Aerial Lift Platform Truck, Scissor Lift Platform, chain guide rail Al-alloy Man Lift , and Dock Ramp .
It is widely used for rescue and maintenance.

2. The filter is damaged, and the debris enters the watch, causing the gear to be stuck;
3. Because the flow rate is too large, the bearing wears, and the elliptical gear collides with the internal helium, causing the gear to get stuck.
Treatment method: 1. Clean the flow meter and pipeline;
2. Repair the filter;
3. Replace the bearing to ensure flexible operation of the gap.
Second, the elliptical gear rotates, the pointer does not move or when the time stops. Causes: 1. The rotating fastener is sliding, damaged or inflexible;
2. The magnetic coupling slides;
3. The character wheel component is stuck.
Treatment method: 1. Re-fix the fasteners to remove the inflexible parts;
2. Check whether the magnetic coupling is flexible and the magnetic strength is strong;
3. Troubleshoot the character wheel components.
Third, the flowmeter negative error is large: 1, bypass valve leakage;
2. The elliptical gear metering inner wall or bearing is damaged or corroded by grinding;
3. The flow rate is lower than the lower limit;
4. Magnetic coupling sliding or gear system periodic obstacles;
5. The actual liquid viscosity is less than the viscosity of the test solution.
Treatment method: 1. Check the bypass valve;
2, replace the bearing, check the gear, adjust the gap;
3. Increase the flow rate;
4. Repair or replace the magnetic coupling or gear system;
5. Select the test fluid that is close to the actual liquid viscosity to check the flowmeter or make a viscosity correction.
Fourth, the flowmeter positive error is large: 1, the flow has a large pulsation or contains gas;
2. The actual liquid viscosity is greater than the test liquid viscosity;
3. When the small inlet valve is closed, the medium is not filled with the metering chamber.
Treatment method: 1. Reduce flow pulsation or increase gas separator;
2. Select the test fluid that is close to the actual liquid viscosity to check the flowmeter or make viscosity correction;
3. Use the flow meter outlet valve to regulate the flow of the medium.
5. The indication value of the secondary meter is more than one indication value of the table. The fault is caused by the vibration of the transmitting blade, which can be solved by appropriately adjusting the pressure of the damping piece on the blade.
6. The indication value of the secondary meter is less than the value indicated by the primary meter. Cause: 1. The fastening screw at the signal blade is loose;
2. The transmitter is dropped.
Treatment method: 1. Fasten the locking screw;
2. Adjust the gap between the transmitter blade and the transmitter.
Seven, the second table does not indicate the reason: 1, the line is open or short circuit;
2. The transmitter is damaged.
Treatment method: 1, carefully check the line;
2. Replace the transmitter.
