Turbine flowmeter to which attention should be paid before production and after production requirements

When we buy back a turbine flowmeter USES, we * have to for the performance and structure of the turbine flowmeter, the working principle of to have a full understanding, as a measure of traffic flow meter, turbine flowmeter work also follow the general flow process, for turbine flowmeter in the commissioning and normal operation of the problems that may occur, this article to remind friends should pay attention to the following: u new commissioning new type selection design or installation of turbine flowmeter measurement system; After we install check, after confirmed, should work for commissioning test. We in the commissioning work, must be conducted in accordance with the following procedures: 1. * first, close the switch valve and control valve of turbine flowmeter; Again, slowly open the bypass valve. 2. After start the turbine flowmeter. In the startup turbine flowmeter work, going to have some problems: (1). With electric remote integrating turbine flowmeter, first connect the power cord and signal lines, preheated. Our solution is: first, slowly open the turbine flowmeter in front of the switch valve; Then slowly open the turbine flowmeter after regulating valve; After slowly close the bypass valve, make the turbine flowmeter work under normal traffic. (2) when the measurement of body temperature is very high, and the temperature of the temperature difference is very big to the environment. Our solution is: when will preheat for metering system; Allows the turbine meter and piping system slowly heat up, so as to ensure the normal work of the turbine flowmeter. 3. Later, we observed record all operation parameters change state, such as: temperature, pressure, etc. If the system is not too big vibration and noise and leakage; And, after a stable operation for a period of time, end of commissioning. U run normally after running normally, we can put into normal operation. In the process of operation, by the use of turbine flowmeter and maintenance; Operating personnel should do the following several aspects: 1. Regular inspection on measurement system, maintenance. Operators of turbine flowmeter, inspect valve and piping system. Operators of equipment maintenance mainly in: a. Safety valve, metering valves and alarm protection devices; b。 Flow display instrument, recording device, compensation device such as flow auxiliary equipment; c。 Filter, venting device and other supporting facilities. 2. Startup and shutdown of the turbine flowmeter work, we should be performed in accordance with the order of the preproduction. 3. During normal operation, the operator should always pay attention to the measured medium parameters such as pressure, temperature, flow rate and viscosity; See if these parameters conform to the scope of application of turbine flowmeter.
