Waist wheel flowmeter maintenance and maintenance methods

Waist wheel flowmeter requires frequent maintenance and maintenance. The performance of the instrument will be greatly reduced for a long time. The user of the waist wheel flowmeter needs to understand the daily maintenance and maintenance of the instrument. The user often maintains and maintains the instrument and can ensure the instrument. Work in the best condition. Here are the steps for the maintenance and repair of the waist wheel flowmeter:

One, waist wheel flow meter daily maintenance and maintenance Waist wheel flow meter does not require regular maintenance and maintenance, as long as the reducer or the adjustment mechanism above the parts of the wheel are often lubricating oil, will ensure the normal operation of the instrument.

1. Lubricant: Silicone oil or clock oil 2. Filling cycle: Continuously running flow meter refuels once every six months; discontinuously running flow meter refuels once every other year. The flowmeter with the oil filling hole needs to be refueled once every half-month, and the refueling amount should not be less than 10ml each time.

Second, the maintenance and maintenance of waist wheel flowmeter operation in order to prolong the service life and measurement accuracy, should pay attention to make the following work during the operation process.

1. Cleaning the filter to ensure that the filter is in a good working condition is a necessary condition for normal operation of the flowmeter. During operation, the pressure loss before and after the filter is observed. When the pressure loss is greater than 0.05 MPa, the filter should be cleaned.

If there is no pressure gauge before and after the filter, the visual flow size determines whether it is necessary to clean the filter. If the other conditions do not change, the flow indication is reduced by 30% from the predetermined value, and the filter should be disassembled for cleaning.

2. Use within the flow rate and pressure range specified by the flowmeter nameplate, do not exceed the limit;

The allowable overload capacity of the flowmeter is 20 but it must not exceed 30 minutes. Long-term overload operation will accelerate internal wear and may reduce metering accuracy.

3. Note the presence or absence of abnormal sound inside the flowmeter. As described above, vibration and noise are very small during normal operation. If the vibration and noise increase, it should be stopped to check the cause;

4. Do not make the liquid flow backwards. 3. The waist cycle flow meter verification cycle 1. Frequently used and continuously running flow meters. To ensure the measurement accuracy, it is recommended to recalibrate once every six months and at most not more than one year. Or according to the technical supervision department prescribed periodic verification.

2, the flowmeter fails, after the sensor is opened and repaired, it needs to be re-verified before it can be used;

3. The flowmeter is calibrated. If the basic error is out of tolerance, it can be adjusted by replacing the gear.

4. Verification liquids: diesel or other oils, but not water.
