Steam flow meters need to pay attention to those problems after use? How to clean and reload them? What kind of problems we need to pay attention to is not only the service life of the product but also the protection of the product itself. Below we will introduce you to the issues that need attention. Convenient for your future use.
When installing the steam flowmeter, the indicator must be placed under the pipeline so that the vertical axis of the flowmeter is less than ±5 degrees perpendicular to the ground, so as not to affect the measurement accuracy. Before the flowmeter is operated, the damper cavity must be filled with the damping fluid. The vent hole of the water injection hole and the bolt at the water discharge hole of the damper can be removed, and the damping fluid is injected. The liquid flowing out of the drainage hole has no yellow rust and When dirt is present, tighten the bolts on the drain hole and continue to inject it to the overflow for 30 seconds. When the liquid level is unchanged, tighten the water injection hole and the vent bolt. The damping fluid can be used with local tap water or anti-rust solution. The rust preventive solution is a mixed solution of clean water with 0.5 cc boiler scale inhibitor and 0.5 cc deoxidizer (hydrazine).
How to dismantle the steam flowmeter: In order to ensure the measurement accuracy, the steam flowmeter should check the flowmeter for long-term continuous use at least once a year. Remove the flowmeter from the pipeline and remove the wires that connect the remote instrument. Remove the indicator fastening bolts and remove the indicator without malfunction. Do not disassemble or move any part of the indicator. Unscrew the water inlet plug first, then unscrew the drain plug to release the water. Unscrew the ten cap nuts and remove the shunt tube. Unscrew the four fastening bolts and remove the sealing plate and reduction gear set. If the damping chamber body and the sealing plate are difficult to separate, use two M10 screws to open.
Place the sealing plate horizontally, unscrew the fastening screw, and remove the reduction gear set from the sealing plate. Be careful not to damage the active magnetic steel and unscrew the M3 screw to disassemble the reduction gear set, taking care not to damage the jewel bearing. Remove the top pin and remove the rotor. The shaft will be taken out of the damping chamber. Be careful not to lose the adjusting washer. Turn the nut under the rotor clockwise to remove the graphite bearing. Be careful not to damage the graphite bearing.
Remove the four tightening nuts to separate the damper chamber from the housing. Do not remove the sleeve from the damper chamber. If it is necessary to remove it, note that the thread is left-handed. Do not disassemble the nozzle and nozzle. When disassembling, be careful not to move the relative position of the two. Such as mobile metering accuracy is not guaranteed. Loosen the four nuts of the damping chamber body to remove the damping chamber body from the housing. If it is difficult to separate, use two M6 screws to top down. Carefully remove the damper chamber body, taking care not to damage the rotor and the “O†ring seal.
The steam flow meter removes the top pin and then removes the rotor for careful inspection. Be careful not to bend the shaft. Loosen the four fastening screws under the rotor and remove the gland, spring and graphite bearing. Be careful not to damage the graphite bearings. Loosen the two M5 socket head cap screws on the nozzle, remove the nozzle, loosen the four fastening bolts, and remove the sealing plate. If it is difficult to separate, use two M10 screws to open it.
