Description
Technical field
The utility model relates to a kind of water conservancy diversion and gets rid of husky device, is specifically a kind ofly provided with the submersible sand discharging pump suction casing that water conservancy diversion gets rid of husky device.
Background technique
In the process of mining, draining is an important problem always.
Flame-proof type submersible sand discharging electric pump obtains general application because it is easy to use, but the stress of submersible sand discharging pump suction side motor bearings and the wear condition of impeller ring, have impact on its working life.
At present, the main shaft cantilever end of multistage submersible sand discharging pump is longer, its suction side supports the mode adopting sliding bearing, there is bearing fit gap, after silt enters sliding bearing, wearing and tearing aggravate, and main shaft lower end are swung excessive, cause the bearing of main shaft end overheated because of stressed increase, impeller ring excessive wear, shortens the working life of electric pump bearing and impeller simultaneously.
For this reason, architecture advances is carried out to the suction side of submersible sand discharging pump, set up water conservancy diversion and get rid of husky device, enter effectively to avoid operating silt, guided liquid-flow enters impeller, improve Pump Suction Nozzle flowing state, reduce the wearing and tearing of Zhuzhou end sliding bearing and impeller port ring, improve the bearing of submersible sand discharging pump suction side and the working life of impeller.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, solving main shaft end sliding bearing in submersible sand discharging pump working procedure swings excessive after wearing and tearing because silt enters, the bearing of main shaft end is overheated because of stressed increase, impeller ring excessive wear simultaneously, cause the problem that the working life of the bearing of submersible sand discharging pump suction side and impeller is shorter, provide a kind of and be provided with the submersible sand discharging pump suction casing that water conservancy diversion gets rid of husky device.
The utility model solves the technological scheme that its technical problem adopts:
Be provided with the submersible sand discharging pump suction casing that water conservancy diversion gets rid of husky device, comprise the main shaft of submersible sand discharging pump, water inlet base and pump cover, on described main shaft, key is connected with impeller, and the contact position of impeller and pump cover is provided with choma, and described main shaft end is provided with sliding bearing;
Described main shaft is also provided with water conservancy diversion and gets rid of husky device, described water conservancy diversion gets rid of husky device between impeller and sliding bearing, and the bottom that water conservancy diversion gets rid of husky device is positioned at outside sliding bearing;
Described water inlet base is fixedly installed bearing support, and the sliding bearing of main shaft end coordinates downwards and stretches in bearing support.
Concrete, described water conservancy diversion get rid of husky device comprise be arranged on main shaft get rid of scrim and annular be arranged on get rid of scrim surface get rid of husky muscle, described in get rid of scrim cross section be "eight" shape, the bottom of getting rid of scrim is positioned at the upper outside of sliding bearing.
More specifically, get rid of scrim key described in be connected on main shaft.
More specifically, get rid of husky muscle described in and be arranged at the outer surface getting rid of scrim.
Concrete, described bearing support is connected with water inlet bolt of lower base.
Of the present utility modelly a kind ofly be provided with the beneficial effect that water conservancy diversion gets rid of the submersible sand discharging pump suction casing of husky device compared with prior art produced and be:
1) the utility model is reasonable in design, main shaft is provided with water conservancy diversion and gets rid of husky device, get rid of scrim and get rid of husky muscle acting in conjunction under avoid operating drift to enter sliding bearing, reduce the wearing and tearing quickening that sliding bearing causes because of influence to sediment, guided liquid-flow enters impeller simultaneously, improves the flowing state of submersible sand discharging Pump Suction Nozzle;
2) bearing support is set on water inlet base, and with the sliding bearing of main shaft end with the use of, reduce the wearing and tearing of impeller port ring simultaneously, improve the working life of submersible sand discharging pump main shaft upper bearing (metal) and impeller, effective solution main shaft cantilever end swings excessive, causes the problem of bearing running hot and impeller port ring wearing and tearing, submersible sand discharging pump reduced lifetime.
