GRAND POWER Water and Steam Integrated Sampling Unit INSTRUCTION Model: CXD JILIN CITY GRAND POWER EQUIPMENT CO., LTD. GRAND POWER 光大电力 I. Summary This unit is adapted to pre-treatment the sample of water and steam for chemical analysis of thermo-equipment, manual sampling, on-line quality analysis of water and steam, computer supervising of the checked parameters. This unit composes of three basic sections: CXD series Sampling Unit of Chemical analysis, which functions in pre-treatment, manual sampling, providing eligible sample for on-line chemical analysis; Analysis instrument screen, on which installs on-line chemical analysis instrument and record displayer etc.; Computer control system, which functions in data collection, treatment, display, reports print, supervising, and epigynous computer control communication etc. Clients can select part of the unit or select all according to demand. II. CXD series sampling unit of chemical analysis 1. Technical characteristic Using a total complete new techno-route, this unit acquires outstanding benefit that other sampling units cannot match, either domestic or overseas. In detail, the characteristics are as below: (1) The sampling unit adopts high-efficiency temperature-pressure reductor (with patent) for fluid of high-temperature and high-pressure. When fluid of high-temperature and high-pressure (such as water, steam etc.), flows along this unit, the temperature and pressure will be reduced, that is the unit works with double functions, one is as the cooler of traditional sampling unit, the other is as the reductor. (2) The sampling unit is not set with pressure-only reductor, which puts an end to the traditional disadvantage caused by reductor block resulted in too much maintenance. (3) The sample flows along the high-efficiency temperature-pressure reductor in a status of deep puffing, with high heat-exchange efficiency. Under the same condition, the usage of the cooling water is only 1/2 2/3 that of the existing cooler. (4) The sample flows along the pipes of the high-efficiency temperature-pressure reductor with speediness that helps the wall of pipes self-clean. (5) The sampling unit adopts a new-type filter, pole-style filter (with patent), barring mechanical impurity granule with diameter over 1.4mm without changing the composition of the water sample basically. Pole-style filter can self-clean for the large flux of the sample, block-proof, if need be, the exhaust drainage valve can be started to clean the filter. The pole-style filter is solid and durable, exempt from maintenance. (6) The sampling unit has a compact structure occupying little space, for example, ten-point of sampling unit is 2.5m long, 0.65m wide, and 1.6m high, every point of sampling added, only 0.2m longer needed, without changing of width and height, therefore, the occupying area is only 3/5 of the current sampling unit. 2. Working conditions (1) Temperature of the environment:540 (2) Power supply: 230V10%,50Hz, 2KVA (3) Cooling water: A: Temperature: 0.2MPa C: Flux: subject to the number and the temperature of sampling points, fifteen points of sampling designed according to 30T/h D: The cooling water of the temperature-pressure reductor adopts de-salted water, without rot, dirt or pollute. 3. Main technical index (1) Under the condition of the temperature not higher than 560 and the pressure not bigger than 35Mpa, the temperature of the treated water is about that of the cooling water plus 5(1 GRAND POWER 光大电力 ), the pressure is smaller than 0.3Mpa. (2) The flux of water sample: 1500ml/min (3) Temperature of the outlet water can be set an alarming rating by the round detector by which the max absolute error measured should not be higher/lower than 1. Any exceeding of the alarm value will cause automatic alarming. The normal alarm is set at 4050. (4) Pressure safety valve of the outlet water sample is set at 0.62.8Mpa, adjustable. Inlet of cooling water has pressure-overloading alarm, with lowest setting at 0.2MPa and highest setting at 0.8MPa. 4. Formal dimensions Seventeen-points sampling unit is 3.6m long, 0.65m wide and 1.60m high. 5. Debugging procedure 5.1. Preparation before operation 5.1.1. According to the system diagram, be familiar with the positions and functions of all sections for the sampling unit. 5.1.2. Regulate the pressure limits on the contacts of cooling water, and check the alarm system if normal. (1) Set the pressure meter on the contacts of the inlet cooling water pipe with a limit at 0.2MPa0.8MPa. (2) Set the pressure meter on the contacts of the outlet cooling water pipe with a limit at 0MPa, and the pressure difference to the inlet not lower than 0.2MPa 5.1.3. Power on the round detector, set the sampling cycle and alarm values according to Instruction settings. (1) Max. value of alarm is set at 4045 (2) Min. value of alarm is set at 0 5.1.4. Check the nodes, airproof parts, fastening parts of the sampling un
