QYW70-60pneumatic desilting unloading submerged pump product instruction
QYW70-60pneumatic desilting unloading submerged pump beautiful appearance, small size, light weight, large flow, overflow part is made of a downdraft structure, semi open impeller, use ZL107 material, through ≤ 14mm particles, sewage capability is extremely strong, not because the inhalation of small solid particles or fibers, surface clogging, nor by inhalation abrasive medium and premature failure.
QYW70-60pneumatic desilting unloading submerged pump overall structure is simple, installation and repairand maintenance is convenient to move, in the working surfacecontaining gas and coal dust using absolute safety. Equipped withmuffler and exhaust, greatly reduces the noise, the measured ≤ 75db(A), greatly improving the underground working conditions.

QYW70-60pneumatic desilting unloading submerged pump use note
1. The new pump in use before, should be in the interview running time,pressure of 0.4---0.5i MPa, about ten minutes drive pump, check whether it is normal operation, the amount of water whether it meets the requirements, whether the flexible start.
2. Air inlet rubber hose cloth diameter shall be not less than 25 mm, the working pressure shall not be less than 0.4 MPa, otherwise it will affect the normal work.
3. In the installation quick couplings, must first impurities in the tube and the joint of the blowing, ensure clean and dry air, lest impurities intothe shell, causing parts wear or rotor stuck not running.
4. Before opening the pump, oil mist device needs to be filled withlubricating oil, and adjusted according to the requirements of the oilvalve. In the process of work, according to the provisions of eachclass to the oil mist injected HJ10 or HJ20 machine oil a. Not work in the absence of lubricating oil, lubricating grease is Wang tosubstitute.
5. The impeller nuts must be padded retaining washers, to prevent the rotor is inverted to loose, causing friction and sinking of the impellerand pump body.
6. n the replacement of wearing parts such as leaves the sealing ringassembly and disassembly process, can not use the hammer percussion, with precision so as not to damage the internal parts of the. In continuous use fifteen days, should be cleaned once a wind pump open, maintenance.
