Description of drawings
Fig. 1 is the structural representation of straight connection type Centrifugal Sand Pumps
Embodiment
A kind of as shown in Figure 1 straight connection type Centrifugal Sand Pumps, its sand pump pump case 2 are circle pump shell structures, and its centrifugal impeller 3 is semi-open type structures, and pump case connects the shell of power motor 12 by adpting flange 5; In the axis hole in the middle of the adpting flange, impeller shaft 6 connects power motor axle 7; Between the axis hole in the middle of its impeller shaft and the adpting flange mechanical seal 8 is arranged, bearing 9 and axle envelope 11.
Pump case and power motor are connected to flange-type and directly are tightly connected fully, and are fixed on the base 13.Also be fixed with control box 14 on the base 13.
The impeller shaft of adpting flange and Qi Nei, mechanical seal, bearing has a grease chamber 10 of playing lubricated cooling seal action between the axle envelope.
The import of sand pump pump case is provided with suction flange 1.
Fastening between impeller and the impeller shaft by lock bolt 4.
The installation of pump and use
Sand pump should behind the installation in position should keep the skid body integral hoisting of pump and motor pump to be in level, and tighten the connecting bolt of skid body and base when installing.
The suction pipe of pump and pressure tube should have the support of oneself, and pipeline weight must not be born by pump.
When the pump mounting point is higher than liquid level (noting in the suction journey allowed band of pump), should be at the terminal dress of suction line bottom valve, the bottom valve throat area should be greater than inhaling people's tube section long-pending 50%.Be at pump and can not adorn bottom valve when pouring in down a chimney work (being that the pump mounting point is lower than liquid level), but should be on suction pipe installation and control valve and filtrating equipment, prevent to cause in the foreign material suction pump impeller and pump to damage.
Before installing, pump must thoroughly remove mixed and disorderly substances in pipe, as welding slag etc.; And check that not part, parts damages are arranged.
Priming of pump stops and turning round:
Priming of pump.Prepare essential tool.Check that lubricating cup indication pasta absolute altitude can not be lower than 45mm.Rotate easily with hand, and weight is even, checks to have or not stridulation, after should eliminating, can drive.
Start moving motor, check turning to of pump.Forbid to reverse.
When being lower than liquid level (pouring in down a chimney situation) in the pump mounting point, the pump prestart will be opened the gate valve of pipeline, and liquid is full of in the pump.When being higher than liquid level (vacuum condition) as the pump mounting point, pump is wanted pump priming and exhaust at prestart, makes in the pump and the interior full of liquid of suction line, air in the discharging pump.
Behind the actuating motor, slowly open the discharge gate valve, be adjusted to required working pressure, and observe working condition.
Centrifugal pump does not allow to regulate with the way that turns down centrifugal pump population valve the flow and the pressure of pump when normal operation, in order to avoid form safe operation and the working life that cavitation erosion influences centrifugal pump.
Closing pressure pipe closer valve.
Stop motor.
Close and inhale people's gate valve.
Must silt in the pump be cleaned up with clear water after each termination of pumping.
The running of pump and maintaining:
The temperature rise situation of running check pump and motor mainly is the bearing temperature rise situation, the highlyest is no more than 75 ℃.
Note observing oil cup of oil machine oil situation, answer hard stop to check mechanical seal and outside framework oil seal, can move after the processing as oil starvation or machine oil muddiness.
In operation process, answer the hard stop inspection during as discovery noise and undesired sound, can move after fixing a breakdown.
Observe ammeter, whether manometric reading is normal.
The dismounting of pump and assembling, adjustment
Dismounting:
Pull down the end cap flange, more fastening impeller left handed screw is taken off, back out impeller with the instrument left hand direction then.Regulating under the pump bracket of notopodium gap has fine adjustment screw, after mixing up acorn nut of bearing support is tightened.
Assemble sequence is opposite with demounting procedure.
Adjusting the two-way gap of impeller both ends of the surface requires within 0.1-0.15mm.Move main shaft with hand-screw, guarantee running smoothly,, more do not allow axial motion, tighten each screw after adjustment finishes without any the hair fastener sensation.
Mechanical seal adjusted when dispatching from the factory is good, user's dismounting adjustment privately, otherwise accept the consequences by oneself.
