Description
Technical field
The present invention relates to a kind of pump housing technical field, particularly relate to a kind of Veritical mud pump.
Background technique
Slurry pump is also an a kind of popular concept of wide in range pump, different regions, custom, and the pump-type finally related to can not be the same, the slurry pump that this entry is set forth be in most meaning a kind of pump-type: the slurry pump applied of field of oil drilling.In fact, sewage pump, some non-clean waterpumps such as Pulp pump and slurry pump also have on call general in.What this entry was set forth to reader is the slurry pump of drilling applications.Pump is conveying liquid or the machinery making fluid pressurization.It sends the mechanical energy of prime mover or other external energies to liquid, and liquid energy is increased.Pump is mainly used to the liquid such as conveying water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal, also can conveying liquid, gas mixture and the liquid containing suspended solids.Pump can be divided into positive displacement pump, driving type pump and other types pump three class by working principle usually.Except classifying by working principle, also can by additive method taxonomy and nomenclature.As, can motor-drive pump and turbine pump etc. be divided into by method for driving; Single-stage pump and multistage pump can be divided into by structure; Boiler feed pump and metering pump etc. can be divided into by purposes; Water pump, oil pump and slurry pump etc. can be divided into by the character of conveying liquid.According to or without axle construction, straight line pump can be divided, and conventional pump
Slurry pump, refers in drilling process to the machinery of the washing solution such as slurry conveyed or water in boring.Slurry pump is the important component part of drilling equipment.At conventional direct circulation probing Zhong ﹐, it is by earth's surface flushing medium--Qing Shui ﹑ mud or polymer flush fluid are under pressure, through the bottom of too high pressure soft pipe ﹑ water tap and drill string central hole direct sending drill bit, to reach cooling drill bit, the landwaste cut removed and is transported to the object on earth's surface.Conventional slurry pump is piston type or plunger type, and driven the crank up of pump by power engine, bent axle drives piston or plunger to move reciprocatingly in pumping cylinder by crosshead again.Suck and expulsion valve alternating action under, realize the object of force feed and circulating flushing washing lotion.The pressure size of pump depends on the depth of boring, washing solution process passage resistance and carry the character etc. of washing solution.Hole darker, pipe resistance is larger, and the pressure of needs is higher.With the change of work bore diameter, the degree of depth, require that pump delivery also can be regulated at any time.In the mechanism of pump, be provided with gearbox or regulate its speed with oil hydraulic motor, to reach the object changing discharge capacity.In order to the Bianization ﹐ slurry pump of the pressure and discharge capacity of accurately grasping pump will install flowmeter and pressure gauge, make at any time driller understand pump fortune turn situation, differentiate that in hole, whether situation normal prevent generation drilling accident by pressure change simultaneously.
Before slurry pump start, please check whether intake pipe, outlet pipe have blocking, whether bearing annotates butter forwards, backwards, checks whether packing is full of.Should high-pressure clear water pump be equipped with during slurry pump work, the clear water being greater than slurry pump pressure be transferred to leakproof filler, filler is protected, during slurry pump work, must not flushingpump be closed, otherwise, hermetic unit rapid wearing will be made.Whether the gap between impeller and backplate is reasonable, very large to slurry pump aging effects.Gap is unreasonable, then produce noise and vibration during pump running, flow passage components damage very soon, and when therefore changing impeller, should note making gap meet drawing requirement, gap adjusts, and is undertaken by the adjustment screw on rear bearing body.The permission of slurry pump is inhaled journey and is measured when carrying clear water, should consider that mud is on the impact sucting ability when pumping slurries.Should there be special maintenance man in construction department, is responsible for the M R to construction plant.Regular checks slurry pump and other machinery, safeguards, the problem that occurs early is solved, in order to avoid cause shut-down.The size of sand grain should be noted during construction, will the easily worn part of running check slurry pump when particle is large, so that on-call maintenance or replacing.Fragile parts mainly pump case, bearing, the impeller etc. of slurry pump.Adopt advanced Anti-wear Measures, improve the working life of easily worn part, the input of engineering can be reduced, enhance productivity.Answer standing fragile part, in order to changing in time simultaneously.
Current existing slurry pump runs stable not, easily produces larger noise during use, easily occurs pulsation and stirring, shears slurries phenomenon, cause the pump housing to block.
