Installation b is different, vertical pump for the overall connection, installation is easier, and horizontal pump after installation needs to be adjusted for precision. Maintenance difficulty is different, vertical pump maintenance is difficult, such as maintenance impeller need to remove all the upper part can be carried out, and horizontal pump is relatively easy. In the process of opening the pump in use, sometimes it will appear blockage phenomenon, then how should we solve it? Here's a specific introduction for you. To ensure the safe operation of critical equipment in the pump is mainly used for catalyst injection, to promote the polymerization in the pre-condensation kettle, the final condensation tank in the condensation reb. Polyester process requires that the catalyst must be in a certain proportion of people, and the stop time can not exceed 15rain, otherwise the melt viscosity will be reduced, product quality and so on. In order to ensure the smooth operation of the catalyst pump, some guarantee measures must be taken. Regular replacement of lubricating oil and wear parts pump internal main moving parts have worm, worm wheel, slider, fixed new piston and so on. Wear of these components will directly result in reduced pump flow or no amount at all.

本系列泵是單級、雙吸、水平中開式離心泵，適用于汲送清水和無腐蝕性的液體。介質(zhì)溫度80℃。軸承體通人冷卻水后，可輸送130℃以下的熱水。改變密封環(huán)、軸套和葉輪的材質(zhì)，可以輸送含有泥沙的渾水。改變承壓零件的材質(zhì)，可以提高泵的進口壓力.泵的軸封一般采用軟填料密封，如有特殊要求，也可改裝機械密封。從電機方向看泵，泵為逆時針旋轉，按用戶要求，也可改為順時針旋轉。jdhuiquan4.13

When installed during the anti-rust guarantee period of the pump, it is not disassembly and washing. Cleaning should be removed when abnormal or exceeding the anti-rust guarantee period, and should meet the following requirements: The disassembly order of parts and components should be in accordance with the requirements of manufacturers; parts and components should be free of rust, often cleaned and qualified, their mating surface should be coated with a thin layer of lubricating oil; Pump leveling and search should be carried out according to the installation instructions provided by the manufacturer. The steam separator shall be installed in accordance with the following requirements: The installation level deviation is not greater than 1/1000, the pipe connected with the pump should not be too long, the flange bonding surface should be tight, the water inlet hole of the soda separator should be connected with the external water supply pipe, and the pipeline should be kept open. Pump commissioning should meet the following requirements: The car should be flexible, no block, vacuum control valve should be adjusted to the appropriate opening, pump filler function of the cooling pipe should be smooth, should be injected into the pump body water, the car rinse clean.

根據(jù)水泵行業(yè)規(guī)定，Sh型與S型兩大系列中開泵并存，直至統(tǒng)一設計出新型泵代替這兩個系列時為止。本產(chǎn)品主要用于工廠、礦山、城市、電站給水農(nóng)用排澇灌溉、各種水利工程用泵和采暖空調(diào)系統(tǒng)等場合
