Mechanical disc recorder pneumatic test pump Source: Cape Air Mechanical Analysis: Cape Air Time: 2015-1-10 16:51:40 Views: 362 times mechanical disc recorder pneumatic test pump Our company specializes in the production of pneumatic test pump, with 15 years experience in manufacturing R & D. You can customize different professional pneumatic pressure and flow test pump. Nitrogen (air) pressure test equipment airtight maximum pressure reached 160MPa, occupy the highest level. Mechanical disc recorder pneumatic test pump medium chart recorder manual: I. Overview: Medium chart recorder with automatic balancing the introduction of advanced technology cleverly used the instrument, so that the instrument has a very high price-performance ratio. This instrument has a simple structure, high sensitivity, recording stable, easy maintenance. The product is based on our metallurgy, electric furnace, heat treatment, food processing and other characteristics of the industry, specially developed products. In the heart of the instrument (balance with slide resistance), this product uses a conductive plastic potentiometer, improved resolution, Wound life than ten times higher than the precious metals, instead of more traditional gear transmission structure chart, and reducing instrument member, thereby improving the reliability of the instrument. Products using high-tech optoelectronic integrated circuit technology to control the alarm system with independent alarm, alarm high precision, instrument light weight and many other features, advantages. Second, the main technical parameters: 1. Indication accuracy: ± 0.5% 2. Record Accuracy: ± 1% 3. Control accuracy: ± 0.5% 4. Setting range: 0 to 100% (two) 5. Travel time: ≤5S 6. Indication dead zone: ± 0.25% 7. Ruler scale length: 550mm 8. Record the effective width: 87.5mm 9. Recording paper speed: 24 hours / week 10. Output contact capacity: AC 220V1A (AC non inductive load) DC 28V2A (pure resistive load) 11. Working environment: Temperature 0 ~ 50 ℃ Relative humidity ≤90% 12. Power supply voltage: 220V ± 10% 50Hz ± 5% 13. Power consumption: ≤20VA 14. Meter Weight: 8kg 15. Dimensions: 288 × 288 × 200 16. Hole size: 260 × 260 three model specifications: can be customized according to user requirements for single continuous recording technology has set four electrical contacts, set alarms and external wiring instrumentation: A, the set value method rotating knob, red Pointer recording paper sliding scale based on the red pointer on the recording paper indicated, that is needed to control the position. When the meter is running higher than the record pointer red pointer, red light, instrument control contacts open. Conversely, when the meter is running below the red pointer record pointer, yellow light, instrument control contact closure. Limit alarm settings, press and hold the button panel indicates the lower limit, the lower limit rotating the knob, then the instrument will be based on the lower black pointer adjustment knob is rotated to rotate. Black pointer instrument according to the scale indicated on the dial, namely the desired control position. When the meter is running below the black pointer control position, the green light, instrument control contact closure. Conversely, green light, instrument control contacts open. B, under the control of an external electrical contacts instrumentation wiring work normally, ①③ NC, ①② normally open. Upper limit, when the instrument is higher than the red pointer ①③ record pointer off, ①② on. Lower limit, when the instrument is higher than the set point ①③ black pointer off, ①② on. Users can choose according to their own situation. The upper limit of electrical contacts electrical contacts Note: 1,3 wiring equivalent power switch, you can not take five phases, the meter installation: meter is a precision instrument, the installation site recommends the use of the environment should have a good, light bright, clean environment, in line with the instrument technical conditions of temperature and humidity. Should be installed in the mechanical vibration, less corrosive gas. There should be installed near the instrument generates a strong magnetic fields. Sixth, the use of the instrument: wired according to the wiring diagram and check the meter wiring intact, open the instrument table door, turn on the power, LED indicates, the instrument can be used normally. Seven, instrument maintenance: Meter is more sophisticated instruments, it takes maintenance, usually do not use, hoping to remove the stylus, power outages often used when the unit is powered, must take the power switch is turned on, and then use Turn the power switch, so as not to damage the instrument devices. Nine, instrument maintenance, ordering: Please inform the sub-degree temperature and the instrument used when ordering. When the instrument needs repair, please inform the instrument is not a normal phenomenon or the instrument back to the factory.
