Abstract
The utility model is composed of an improved water jet vacuum pump of a structure disperse fixed type. An electric motor and a vacuum tank are both arranged on the upper part of a water tank, at the same time a centrifugal pump and a jet pump are arranged in water, and the bottom of the water tank is provided with four roller wheels, so the utility model has the advantages of compact conformation, little volume, light weight, high efficiency, saving power consumption, moving and convenient maintenance work. The utility model can be used for the enterprises of oilfield, chemical industry and medicine, etc.
Description
A kind of vacuum pump particularly relates to a kind of water injection vacuum pump.
Vacuum pump is enterprise's necessarieses commonly used such as petrochemical industry medicine, the domestic and international oil-sealed rotary pump that generally uses, just progressively substituted, and water injection vacuum pump is developed by fixed (as shown in Figure 1) portable direction to compact structure by water injection vacuum pump.The shortcoming of fixed water injection vacuum pump is that jet pump, motor, centrifugal pump, water tank and vacuum tank all are decentralized configuration.Centrifugal pump is delivered to water and is dashed circulation under the eminence from the water tank of bottom, the lift height, and power consumption is big, and volume is big, the cost height, fixed-site, very inconvenient on maintenance is used.
Task of the present utility model is: fixed water injection vacuum pump is improved, movably water injection vacuum pump of a kind of integrated type is provided.
The utility model is whole packaged type water injection vacuum pump, and it is to disperse fixed water injection vacuum pump to improve by structure to form.Its major technique feature is the upper right quarter of drive motor upside-down mounting erectly at cyclic water tank, link to each other with centrifugal pump in the cyclic water tank by a jack shaft, left end at centrifugal pump passes through the flange connecting leg, directly link to each other with jet pump, be in the cyclic water tank, be provided with a pipeline on the top of this jet pump and link to each other with vacuum tank flange connecting leg, vacuum tank is placed on the top of cyclic water tank.The left side wall top of cyclic water tank is provided with a water level pipe, surpasses the jack shaft on centrifugal pump top and damages motor to prevent the water surface in the cyclic water tank.Like this, when the motor drives centrifugal pump is worked, just directly the nozzle of the water in the cyclic water tank by jet pump sprayed water, constantly in water tank, circulate, thereby around nozzle, produce negative pressure, make vacuum tank high speed injection gas, reach high vacuum.
Advantage of the present utility model:
1, because centrifugal pump and jet pump all are contained in the cyclic water tank, overcome that fixed water injection vacuum pump is contained on the higher support and the defective that causes water-head, can save electric energy significantly like this, from real work, record, 3 kilowatts of per hour can save electric (is example with the 3BA-9 pump).
2, make the degree of vacuum in the vacuum tank reach as high as 760 ° (0.1), maximum rate of air sucked in required can reach 100 meters
3/ hour.
3, because centrifugal pump is under water, and water has buoyant equilibrium effect (need not diversion) to the pump leaf, institute is so that the axle envelope is never leaked, and cold-proof performance is good, is difficult for bursting by freezing winter.Evidence has improved 3 times than the fixed water injection vacuum pump employed centrifugal pump life-span.
4, because motor and vacuum tank all are contained on the water tank, centrifugal pump and jet pump directly are contained in the water of cyclic water tank.Four rolling is equipped with in bottom at water tank, so compact overall structure, volume is little, and is in light weight, and conveniently moving can use in different occasions.
5, this pump cost is low, disperses fixed water injection vacuum pump to compare with structure, and cost can reduce by 1/2.
The utility model is that the water injection vacuum pump that will generally use at present improves, and it is that bar structure disperses fixed support formula water injection vacuum pump (Fig. 1) to make compact structure, packaged type water injection vacuum pump (Fig. 2) into.Its improvement is that motor 1 upside-down mounting erectly is right-hand on cyclic water tank 12 tops, motor 1 is linked to each other with centrifugal pump 4 in the cyclic water tank 12 by joint sleeve 2 by a jack shaft 3, centrifugal pump 4 is in the water of cyclic water tank 12, the left side at centrifugal pump 4 links to each other with jet pump 6 by flange connecting leg 5, and the top of jet pump 6 has a pipeline to link to each other with vacuum tank 10 flange plate pipelines 9, be provided with a baffle plate 11 in the bottom of jet pump 6, to reduce bubble.In cyclic water tank 12 bottoms four rolling 14 is housed, can makes this water injection vacuum pump do to move arbitrarily.Left side wall top at water tank 12 is provided with water level pipe 13, can make the water surface keep certain liquid level, prevents the too high and infringement motor of the water surface.In the left side wall bottom of water tank 12, drain valve 15 is housed, for convenient for maintaining discharges water.
The working procedure of this water injection vacuum pump is performed such, motor 1 rotates by jack shaft 3 and drives centrifugal pump 4, high pressure water is delivered to jet pump 6, it is formed on every side with water is fluid, high speed injection gas, there is a pipeline to link to each other on the top of jet pump 6, thereby makes vacuum tank 10 produce high vacuum with vacuum tank 10 flange connecting legs 9.
Claims (2)
1, water injection vacuum pump, it is characterized in that cyclic water tank 12, its top is right-hand is equipped with a upright motor 1 of being inverted, motor 1 is by a jack shaft 3, linked to each other with centrifugal pump 4 in the cyclic water tank 12 by joint sleeve 2, and centrifugal pump 4 is arranged on that left end is equipped with jet pump 6 in the cyclic water tank 12, its top links to each other with vacuum tank 10 by flange connecting leg 9, in the bottom of jet pump 6, be provided with the baffle plate 11 of an inclination, four rolling 14 is equipped with in cyclic water tank 12 bottoms.
2, it is characterized in that the left side wall top of cyclic water tank 12 according to the described water injection vacuum pump of claim 1, be provided with water level pipe 13, the bottom is provided with drain valve 15.
