Composite pipe support diving slurry pump
Technical field
The utility model relates to a kind of pump, is specifically a kind of composite pipe support diving slurry pump.
Background technique
As everyone knows, pump is the machinery equipment of carrying liquid or making liquid supercharging.It sends the mechanical energy of prime mover or other external energies to liquid, and liquid energy is increased.Pump is mainly used to carry the liquid such as water, oil, acid & alkali liquid, emulsified liquid, mixed solution, also can conveying liquid, gas mixture and containing the liquid of suspended solids.Pump can be divided into positive displacement pump, driving type pump and other types pump three classes by working principle conventionally.Except by working principle classification, also can and name by additive method classification.As, by method for driving, can be divided into motor-drive pump and turbine pump etc.; By structure, can be divided into single-stage pump and multistage pump; By purposes, can be divided into boiler feed pump and metering pump etc.; By carrying the character of liquid can be divided into clean waterpump, sewage pump, oil pump and slurry pump etc.
Yet slurry pump, refers in drilling process to the machinery of the washing solutions such as slurry conveyed in boring or water.Slurry pump is the important component part of drilling equipment.Slurry pump Zhong conventional direct circulation probing ﹐ it be by earth's surface flushing medium--Qing Shui ﹑ mud or polymer flush fluid are under certain pressure, through the bottom of too high pressure soft pipe ﹑ water tap and drill string center hole direct sending drill bit, reaching cooling drill bit, the landwaste cutting is removed and is transported to the object on earth's surface.Conventional slurry pump is piston type or plunger type, is driven the crank up of pump by power engine, and bent axle drives piston or plunger to move reciprocatingly in pumping cylinder by crosshead again.Under the alternating action of suction and expulsion valve, realize the object of force feed and circulating flushing washing lotion.
Major axis slurry pump, critical piece has the pump housing, impeller, pump cover, axle, have simple in structure, volume is little, lightweight, easy installation, without stopping up, dive length is adjustable; The advantages such as easy maintenance; But its impeller is in the middle of runner.
In existing slurry pump, impeller is to be arranged in spiral casing flow passage, during running, to water pump without plugging performance, certainly will form certain inhibition, thereby be unfavorable for slurry pump work; Wherein between lower cover and spiral case, be all bolted, but only adopt single bolt to fix, fixed effect is not good, is prone to the problems such as connection is not tight.

Wherein whole fixing by bolt A and bolt B between lower cover and spiral case, wherein bolt A is inner fixing from spiral case from lower to upper, and bolt B is from top to bottom from spiral case external stability,
Described rotating shaft bottom is stretched in spiral case, and its pivoting end is provided with impeller, and described spiral case has one for the spiral case neck of impeller is set;
Described impeller integral body is positioned at spiral case neck; The high 5-10cm of described spiral case neck.
According to composite pipe support diving slurry pump described in the utility model, it is characterized in that: described impeller has round shape impeller body, the middle part of impeller body has the fixed hole for being connected with described rotating shaft, in this fixed hole, have the keyway being connected with flat key, on described impeller body, with multiple tracks, be the blade of bending.
The utility model has the advantage of: the utility model provides a kind of composite pipe support diving slurry pump by improving at this, comprises upper cover, composite pipe support, lower cover, spiral case; Upper cover is positioned at composite pipe upper part of the frame, and wherein composite pipe support is also connected with lower cover, between described upper cover, composite pipe support, lower cover three, by bolt integrated connection, fixes, and described lower cover below is spiral case.
Described rotating shaft bottom is stretched in spiral case, the bottom pivoting end of its rotating shaft is provided with impeller, be different from traditional pump housing, and described spiral case has a neck, and this neck is for arranging impeller, and described impeller integral body is arranged in spiral case neck; Because impeller in existing slurry pump is normally positioned at spiral casing flow passage middle part, impeller integral body in the running, can certainly will form certain inhibition to the water in runner and media particle, thereby be unfavorable for slurry pump work; Therefore after improving, described impeller integral body is arranged in to spiral case neck, now, impeller integral body in the running, strengthens media particle passing capacity in water pump spiral casing, and its whole water pump is improved without plugging performance.
The utility model is by after improving, wherein whole fixing by bolt A and bolt B between lower cover and spiral case, wherein bolt A is inner fixing from spiral case from lower to upper, bolt B is from top to bottom from spiral case external stability, here by bolt A and bolt B, from outer side surface both direction in spiral case, be connected and fixed, fixed effect is improved, and after using, also there will not be and connects untight problem even long-time.
The utility model is also made improvement to impeller, first, described impeller has one for the impeller body of circle shape, the middle part of this impeller body has the fixed hole for being connected with described rotating shaft (bottom pivoting end), in this fixed hole, have the keyway being connected with flat key, the rotating shaft position of matching with impeller is also designed with keyway simultaneously, while being connected and fixed, the center hole of impeller and dowel hole are aimed to rotating shaft and flat key positions, then make it be tightened to one under the effect of bolt.
