閥門試驗臺使用前后的檢查與注意

發布時間:2022-08-05 16:26:16   發布人:http://www.madaboutmermaids.com
閥門實驗臺又名閥門測試臺、閥門測試機,現有臥式、翻轉雙抱壓、立式、智能等類型,現就閥門試驗臺使用前后的檢查與注意事項,氣體增壓泵廠家為您做一個解說。
Valve test bench, also known as valve test bench and valve test machine, has horizontal, overturned double holding pressure, vertical, intelligent and other types. Now, the gas booster pump manufacturer will explain the inspection and precautions before and after the use of the valve test bench.
閥門試驗臺使用前的檢查
Inspection of valve test bench before use
(1)檢查實驗臺的機殼是否有裂紋,若有裂紋則不能使用。
(1) Check whether the cabinet of the test bench has cracks. If there are cracks, it cannot be used.
(2)檢查閥門測試臺的絕緣電阻。用500V絕緣電阻表檢測,其絕緣電阻不應小于5MΩ,若低于此值,應打開放水、放氣孔,烘干或曬干后再使用。
(2) Check the insulation resistance of the valve test bench. The insulation resistance shall not be less than 5m Ω when tested with 500V insulation resistance meter. If it is lower than this value, open the drain hole and vent hole, and use it after drying or drying.
(3)檢查閥門測試臺的放氣孔、放水孔、放油孔和電纜接頭處的封口是否松動,如有松動須旋緊。
(3) Check whether the seals at the vent hole, water drain hole, oil drain hole and cable joint of the valve test bench are loose. If they are loose, they must be tightened.
(4)起動前校正電源正負極,以免水泵倒轉,不出水。
(4) Before starting, correct the positive and negative poles of the power supply to prevent the water pump from reversing and no water from flowing out.
(5)閥門測試臺的電纜線好不要有接頭,若有接頭應包扎好,整個電纜線應無破損、折斷現象,否則應更換新電纜。另外,電纜線要架空,不要太長。
(5) The cable of the valve test bench should be free of joints. If there are joints, they should be wrapped up. The whole cable should be free of damage and breakage, otherwise it should be replaced with a new cable. In addition, the cable should be overhead and not too long.
(6)開機前對供電線路、開關進行全面檢查,并在地面通電空轉3~5min,若運轉正常,再放入水中投入使用。
(6) Before startup, the power supply line and switch shall be comprehensively inspected, and the power supply line and switch shall be powered on and idled for 3-5min on the ground. If the operation is normal, it shall be put into water for use.

閥門試驗臺使用中應注意的事項
Matters needing attention in the use of valve test bench
(1)不同型號的閥門試驗臺,應按規定的揚程使用,配用的鋼管、橡膠管或帆管內徑應符合技術要求。
(1) The valve test bench of different models shall be used according to the specified lift, and the inner diameter of the steel pipe, rubber pipe or sail pipe shall meet the technical requirements.
(2)出水管盡可能不要彎曲,及時發現并修補輸水管的破裂處,以減少功率損失。
(2) The outlet pipe shall not be bent as much as possible, and the rupture of the water pipe shall be found and repaired in time to reduce power loss.
(3)閥門試驗臺放入水中或提出水面時,須拉住耳環上的繩子,不能拉電纜線,否則會造成電纜線損壞。
(3) When the valve test bench is put into or lifted out of the water, the rope on the earring must be pulled, and the cable cannot be pulled, otherwise the cable will be damaged.
(4)閥門試驗臺不能抽排污水或含砂量大的水,尤其是采用機械密封的閥門測試臺更應注意這一點。
(4) The valve test bench shall not pump sewage or water with large sand content, especially the valve test bench with mechanical seal.
(5)閥門試驗臺的潛水深度一般為0.5~3m,并應垂直吊起,不能橫臥,更不能陷入泥沙中。
(5) The diving depth of the valve test bench is generally 0.5~3m, and it should be lifted vertically. It is not allowed to lie horizontally, let alone sink into the sediment.
(6)閥門試驗臺電源應按規定選用,電源與水泵的距離不能過遠,電壓應在正常值的±10%之內,并在電源或水泵處埋設一根1m以上的鐵棍作地線,以確保安全。電源須接地可靠,加裝漏電保護器。另外,盡量避免在電源電壓過高或過低時開機,電壓過高,會引起電動機過熱而燒壞繞組;電壓過低,則電動機轉速下降,會造成起動繞組長時間發熱,甚至燒壞繞組和電容器。
(6) The power supply of the valve test bench shall be selected according to the regulations. The distance between the power supply and the water pump shall not be too far. The voltage shall be within ± 10% of the normal value. An iron rod of more than 1m shall be buried at the power supply or the water pump as the ground wire to ensure safety. The power supply must be grounded reliably and equipped with leakage protector. In addition, try to avoid starting the machine when the power supply voltage is too high or too low. If the voltage is too high, the motor will overheat and burn out the winding; If the voltage is too low, the motor speed will drop, which will cause the starting winding to heat up for a long time, and even burn out the winding and capacitor.
(7)閥門測試臺應采用斷路器作控制設備,也可以采用三刀刀開關,但須裝上6A的電熔絲。
(7) The valve test bench shall use a circuit breaker as the control equipment, or a three blade switch, but 6A electric fuse shall be installed.
閥門測試臺因將水泵和電動機潛入水中使用,如果技術性能達不到要求,不但不能抽水,而且還可能造成安全事故,因此須注意閥門測試臺的維護和保養,詳情內容就來我們網站http://www.madaboutmermaids.com進行咨詢了解吧。
The valve test bench is used by submerging the pump and motor into the water. If the technical performance fails to meet the requirements, it will not only not be able to pump water, but also may cause safety accidents. Therefore, it is necessary to pay attention to the maintenance of the valve test bench. For details, please visit our website http://www.madaboutmermaids.com Consult and understand.
