V cone bimetallic thermometer installation method and fault analysis

The v-shaped thermometer factory in jiangsu conical bimetallic thermometer is a kind of high precision, high stability, wide range than wide, measurable medium of the new type of double metal thermometer, flow is based on the principle of continuity and Bernoulli equation to calculate the working condition of fluid flow, as pressure, velocity, or big or hours, the differential pressure value is also changed. So V cone bimetallic thermometer is also known as differential pressure type bimetallic thermometer is one of them, for V cone bimetallic thermometer measurement accuracy is relatively high. Therefore become preferred bimetallic thermometer in the middle of the industrial field. So because of the precision demand also need special attention when installing the following installation techniques: Uh2 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

1, before installation, must pass metrological verification. In the case of confirmed to meet the various technical indicators, shall be in strict accordance with the signal line and the installation requirements of differential pressure gauge. According to different medium, must need our reference standards for different installation and identify, do one to one correspondence relation.

2, when in use, must be ruled out in the exhaust valve signal line each point of the air Uh2 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

3, regular cleaning line signal, and the differential pressure type double metal thermometer, clear clutter. Uh2 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer with two-color thermometer

4, input before, should check the zero. Check the zero, the shut off valve on two meter pressure valve and open the balancing valve. If discover the zero offset, should find out the reason, be adjusted. 5, if discover the differential pressure type of the bimetallic thermometer in values and measured values have obvious difference, should be comprehensive inspection and repair, and metrological verification again.

if improper installation may cause the following failure cause: 1, no 2, always for a long time no order 3 wide fluctuations, directives, not reading I 4, instructions not to return zero 5, small flow directions without 6, big flow can also, small flow directions when no 7, flow rate changes changes to keep pace with 8, instrument K coefficient can not be sure, many data are not consistent.

if encounter the above situation also need not worry, can be in accordance with the troubleshooting thermometer factory first to check 1, first check the V cone bimetallic thermometer is the problem of pressure guide line, to do, pressure pipe unimpeded. Check whether the leak and plug, because if appear such problem, one-way pressure, differential pressure transmitter will appear the phenomenon of the negative pressure. 2, direct access to gas, observation pressure pipe status; If the scene is welding problems, if have been familiar with V cone bimetallic thermometer ontology, can with the equipment at the scene of the operation, if not, you can return the product factory inspections rework.
