Verification of temperature on several issues tanker

1. Selection of the thermometer. JJG443-2006 auxiliary fuel dispenser suppliers requirements thermometer measurement range of -25 ℃ ~ 55 ℃, minimum scale value 0.2 ℃. But now most of the measurement technique used in the actual work organization inexpensive glass thermometer, this thermometer has the following defects: ⑴ fragile glass thermometer; ⑵ glass thermometer inside the oil temperature gauges inconvenient; ⑶ glass thermometer bulb reaction slower. Therefore, it is recommended to select digital display platinum resistance thermometer, indexing the minimum value of 0.2 ℃, the measurement range of -30 ℃ ~ 60 ℃, the use of platinum resistance temperature sensor, built-in battery power, the length (50 ~ 70) cm Stainless Steel Pipe protection, not damaged, eye-catching display, rapid, accurate and convenient.
2. Temperature measurements.
2.1 muzzle oil temperature measurements. When measuring the temperature of the oil gun, oil oiling the metal gauges should always flow from excessive temperature thermometer segment, oil temperature muzzle distance of about 1cm, when the thermometer showing the value of a steady and rapid reading (or tanker Indication measurement of 50% to 70% metal Tank capacity), the recording data.
2.2 Metal Tank oil temperature measurement. When measuring the automatic fuel dispenser temperature gauge metal, glass thermometers, oil lines in the upper rope thermometer, temperature segment can reach the central metal gauges limited (you can stick in the other end of a rope, slightly longer than the overflow cover diameter measurement gauges prevent metal thermometer fall), holding a rope into the metal thermometer gauges, temperature gauges central metal segment arrives late after (3 ~ 5) min thermometer bulb section exposed in front of the liquid quickly reading, recording data.
Another method: When the metal gauges measuring emissions of oil, when the oil into about half of the measured temperature in 盛油容 vessel; or when metal gauges discharge of oil, the thermometer temperature gauge section from row was measured at the mouth about 1cm, until the thermometer shows stable reading value, in order to replace the oil inside the metal gauges.

HTF large pump noise Cause Analysis

Conducting oil mechanical pump, heat pump noisy mainly due to bearing damage or thermal oil circulation pump cavitation phenomena due to high temperatures and thermal oil pump vibration generated support causes of instability caused due to long-term contact HTF pump operation, users use during the course of the oil bearing chamber is not changed frequently, resulting in long-term high-speed bearing long-term operation in the case of poor lubrication conditions caused by thermal oil pump bearing failure, which is conducting oil pump noise. HTF pump should be maintained on a regular basis in daily production, cleaning, the timely replacement of the bearing housing to the bearing lubrication oil. Once the bearing is damaged bearings should be replaced to avoid damage to the pump to produce other components. in addition, the newly installed clients in the use of thermal oil pumps are often used for the first temperature rise too fast or oil rise too high. This will cause HTF produce gas in the pipeline, will instantly explode when these gases in the process of conducting oil pump delivery cycle by conducting oil pump, so when conducting oil pump noise. HTF pump should be used for the first time, the oil should rise slowly and start conducting oil pump, gradually open the inner pipe vent pipe cleaner exhaust gas after the official use thermal diesel hand pump. Yet another is conducting oil pump is installed and export pipeline is not marked anchor or anchor cause instability when using thermal oil pump generates a huge pipe resonance, it will generate noise. it should be a solid pipeline of timely support. I have many years of conducting oil pump production history, production specifications, product safety, long service life can be for the majority of thermal oil pumps provide customers with strong technical guidance free of charge. welcome customers to buy our products conducting oil pump.

Persistence depends on a large tanker used daily maintenance

Safeguard gas transfer pump, help enhance the life of a small tanker. To know nothing mechanical can permanently using it. Persistent machine using a large part depends on the process used for its maintenance is good or bad. So for those familiar with the use and maintenance of small tankers users, use and maintenance vane pump is generally no big problem. However, issues related to the use of those new users do not know where it is necessary to properly learn about.
A relief valve spring can not be adjusted too tight, or make the system pressure, noise and vibration increases, and increased pump bearing wear.
2, V-belt tension should be appropriate, the tension is too small, the belt slippery, causing oil or no oil shortage, but also easy to wear belt tensioning force is too large, the motor shaft and the cng pump shaft to bear additional load (axial direction of the vertical axis) increases, could easily accelerate the motor bearings, pump bearings and seal wear.
