The design of the lumbar wheel flowmeter has been designed to be as simple as possible and easy to use. Therefore, the flowmeter is easy to operate and easy to use, and does not require special tools.
First, the operation of the waist wheel flowmeter and its precautions 1. Before the passage, check whether the installation of the flowmeter meets the requirements of this manual. The flow direction of the liquid is consistent with the direction indicated by the arrow on the flowmeter housing, and the wiring is correct;
2. The flow rate, pressure and temperature range of the liquid should meet the requirements of the specification;
3. For newly laid pipelines or flowmeters that are initially started, the bypass valve should be opened before starting to flush the dirt and impurities in the pipeline with the liquid or other liquid to be tested;
4. Start and stop operation (1) Open the bypass valve to make the liquid flow normally through the bypass valve;
(2) Slowly open the valve on the upstream side of the flowmeter to fill the flowmeter with liquid;
(3) Deflating, loosen the bleed screw on the upper cover 2 (Fig. 6) with a wrench, and release the upper gas, then tighten the bleeder screw immediately;
(4) Close the bypass valve, and adjust the flow rate by the downstream side valve until the request is made. The flow meter enters the normal running state;
(5) Flowmeters that are continuously operated, the operation of stopping the operation is opposite to the sequence of opening;
(6) The flowmeter used intermittently, stop running or start again, only operate (adjust) the downstream side valve.
Second, the monitoring of the waist wheel flowmeter operation During the operation of the waist wheel flowmeter, there is no cumbersome operation requirement, as long as the monitoring operation is normal or not. When the flow rate is too small compared to the required flow rate, the pressure loss on both sides of the filter can be observed. If the pressure loss is too large (›0.05 MPa), the filter should be opened to clean the filter.
Third, the waist wheel flow meter reading and recording pointer dial display display mechanism is composed of a pointer, dial and a small 7-bit mechanical counter, the pointer indicates the lowest number of digits, the indicator of the pointer and the mechanical count The number is the value to be read. For example, the indicator of the pointer is 7.2, the counter number is 0012345, and the flow meter value should be .2. When the application is recorded, the value is recorded in advance, and then the flow meter is turned on. When the metering is finished, the downstream side valve is closed, and the indication value is read again. The latter is subtracted from the former, and the difference is the total volume of liquid passing through the flow meter during this time.
