Abstract
The utility model relates to a through-way type single-stage centrifugal clean water pump, which is characterized by comprising a pump casing, connecting flanges, a mechanical seal water-proof motor and an impeller. The connecting flanges are respectively arranged at two ends of the pump casing, the mechanical seal water-proof motor is fixed in the pump casing, a gap is reserved between the mechanical seal water-proof motor and the pump casing, and an output shaft of the mechanical seal water-proof motor is connected with the impeller. The through-way type single-stage centrifugal clean water pump is simple in structure, convenient to use, capable of reducing accessories and prolonging service life, low in manufacture cost and abrasion rate and small in noise. In addition, water flows out smoothly by means of matching of the mechanical seal water-proof motor, the pump casing and the S-shaped impeller, and operation efficiency is high.
Description
Technical field
The utility model relates to a kind of straight-through type one-stage centrifugal clean waterpump.
Background technique
Mostly big its structure of water pump in the market is to be provided with on the base motor, and motor connects main shaft through coupling, and impeller is set on the main shaft again, could accomplish through impeller then and supply water.Such structure is thick old heavy, and Placement is complicated, and the power loss of motor is big, and power is lower, and motor independence radiating effect is poor, and is fragile.And the various cost of its accessory is high, also can influence the whole working life of water pump simultaneously because of the damage of accessory, can produce higher maintenance expenses again during maintenance.
The model utility content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of straight-through type one-stage centrifugal clean waterpump that can overcome above-mentioned defective is provided, and simple for structure, easy to use, high working efficiency, long service life.
The utility model solves the technological scheme that its technical problem adopted: described straight-through type one-stage centrifugal clean waterpump; It is characterized in that: comprise pump case, adpting flange, mechanical seal waterproof machine and impeller; Adpting flange is separately positioned on the two ends of pump case; The mechanical seal waterproof machine is fixed on pump case inside, has the space between mechanical seal waterproof machine and the pump case, and the output shaft of mechanical seal waterproof machine connects impeller.
Described impeller is a S type impeller.Can drive the S-shaped rotation of current during the rotation of S type impeller, current are directly converged between the space of pump case and mechanical seal waterproof machine, reduce resistance, make water outlet more smooth, improve motor working efficiency.
Described pump case is a cylindrical structural, and the adpting flange that the pump case two ends are provided with also is a cylindrical structural.Columniform straight-through structure is is conveniently installed and used.
The housing of described pump case is provided with handgrip.Be convenient for carrying.
Pump case can directly be connected with water supply line through the adpting flange at two ends, and the mechanical seal waterproof machine directly is connected with S type impeller, and straight-through structure does not need other loaded down with trivial details accessory, and the power of motor loss is low, improves motor working efficiency.
The beneficial effect that the utility model had is: simple for structure, easy to use, reduced accessory, and cost is low, and its wear rate reduces, and increases the service life, and noise is little.And through mechanical seal waterproof machine, pump case and the S type impeller water outlet smoothness that cooperatively interacts, operational efficiency is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, pump case; 2, handgrip; 3, mechanical seal waterproof machine; 4, S type impeller; 5, adpting flange.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; Described straight-through type one-stage centrifugal clean waterpump; Comprise pump case 1, adpting flange 5, mechanical seal waterproof machine 3 and impeller, adpting flange 5 is separately positioned on the two ends of pump case 1, and mechanical seal waterproof machine 3 is fixed on pump case 1 inside; Have the space between mechanical seal waterproof machine 3 and the pump case 1, the output shaft of mechanical seal waterproof machine 3 connects impeller.Impeller is a S type impeller 4.Can drive the S-shaped rotation of current during 4 rotations of S type impeller, current are directly converged between the space of pump case 1 and mechanical seal waterproof machine 3, reduce resistance to water-flow, make water outlet more smooth, improve motor working efficiency.Pump case 1 is a cylindrical structural, and the adpting flange 5 that pump case 1 two ends are provided with also is a cylindrical structural.Columniform straight-through structure is is conveniently installed and used.The housing of pump case 1 is provided with grabs 2 hands, is convenient for carrying and moves.
In the using process, fills with water in pump case 1 drives S type impeller 4 through mechanical seal waterproof machine 3 and rotates.4 rotations of S type impeller produce centrifugal force current are brought in the pump case 1, so S type impeller 4 center pressures reduce, this pressure is lower than the pressure in the intake pipe, just constantly suction water inlet under this action of pressure of water.When 4 rotations of S type impeller, water is got rid of in the pump case 1, at this moment glassware for drinking water has certain kinetic energy, and water compiles in pump case 1, when S type impeller 4 constantly gets rid of water into pump case 1, just constantly from the space of pump case 1 and mechanical seal waterproof machine 3, flows out.And because mechanical seal waterproof machine 3 is in the current, and heat radiation is better, and its continuous service time is long always, using effect is good.
Pump case 1 can directly be connected with water supply line through the adpting flange 5 at two ends, and mechanical seal waterproof machine 3 directly is connected with S type impeller 4, and straight-through structure does not need other loaded down with trivial details accessory, and the power of motor loss is low, improves motor working efficiency.
