Abstract
The utility model discloses a water pump cavitation eliminating device. The device is characterized in that a semi-circular baffle is attached to and arranged on the inner side wall of the top of a front water inlet pipe of a water pump and used for blocking water flows, an air collecting tank is arranged on the outer side wall of the water inlet pipe behind the semi-circular baffle, and an exhaust pipe provided with a valve is communicated with the top of the air collecting tank. According to the device, the phenomenon of water pump cavitation can be effectively reduced or eliminated, so that the damage to the water pump can be prevented.
Description
Technical field:
The utility model relates to a kind of water-inlet tube device that is applied to industrial circulating water pump, more specifically says a kind of device of eliminating pump cavitation phenomenon.
Background technique:
In the circulation or industrial cycle cooling system of thermoelectricity, mostly adopt the cooling and circulating water pump of cooling tower recycling cooling water; And that circulating water pump mostly is discharge pressure is lower, the pump type that flow is larger, its a large amount of water inlets are easy to cause introduces a part of air in intake pipe; When air enters water pump vane ingress, easily there is pump cavitation phenomenon, when serious, water pump is not even inhaled liquid and makes a noise, and pump is running for a long time in this state, will cause blade to damage too early.
Model utility content:
The utility model is for avoiding the existing deficiency of above-mentioned prior art, and a kind of elimination pump cavitation device is provided, and can effectively eliminate or reduce pump cavitation phenomenon, prevents that water pump from damaging.
The utility model is that technical solution problem adopts following technological scheme:
A kind of structural feature of eliminating pump cavitation device of the utility model is: on the inside top wall of the place ahead of water pump intake pipe, laminating arranges a Semicircular baffle for intercepting current, on the intake pipe outer side wall at described Semicircular baffle rear, an air collector is set, the top of described air collector is communicated with the outlet pipe with valve.
The structural feature that the utility model is eliminated pump cavitation device is also:
The top of described valve arranges a glass tube.
Span between described Semicircular baffle and air collector is between 100mm to 200mm.
The height of described Semicircular baffle be intake pipe diameter 1/5 to 1/4 between.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The air that current in circulating water pump are brought intake pipe into can be eliminated or reduce to the utility model, before entering water pump, air drawn, thereby effectively avoid occurring pump cavitation phenomenon, extends the working life of water pump, reduces the maintenance cost of water pump.
Accompanying drawing explanation:
Fig. 1 is the utility model Semicircular baffle structural representation;
Fig. 2 is the utility model air collector structural representation;
Fig. 3 is that the utility model is used view;
Number in the figure: 1 water pump; 2 Semicircular baffles; 3 air collectors; 4 outlet pipes; 5 valves; 6 glass tubes.
Embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, eliminate on the intake pipe madial wall that pump cavitation device is mounted in front about the 1 meter place of the water intake flange of water pump 1 laminating annular and weld half circular baffle plate 2 for intercepting current, Semicircular baffle 2 can adopt thickness to be greater than stainless steel (1Cr18Ni9Ti) material of 10mm; It is highly intake pipe diameter 1/5 to 1/4 between, when flow velocity is high, the height of Semicircular baffle 2 gets the small value, thereby can effectively reduce water flow resistance.Semicircular baffle 2 can be so that aqueous vapor be separated in intake pipe; One air collector 3 is set on the intake pipe outer side wall at Semicircular baffle 2 rears, for collecting gas; The top connection of air collector 3 is provided with the outlet pipe 4 with valve 5, for Exhaust Gas.
In concrete enforcement, as shown in Figure 3, the span between Semicircular baffle 2 and air collector 3 is between 100mm to 200mm, and concrete condition is looked the flow rate of water flow size in intake pipe, and flow velocity is larger, and span is just larger.Outlet pipe 4 is selected internal diameter
garden pipe, length 200mm left and right, valve 5 is welding type or flange-type, can select DN50 type valve; One glass tube 6 can also be set above valve 5, the convenient water level of observing; Glass tube 6 is DN50 type glass tube, and its length is according to the decision of water inlet water level and the pump intake centreline space discrepancy in elevation, with the Placement of valve 5 be water-level gauge formula.
When circulating water pump 1 operation, the air of being brought into by water in intake pipe is free in the top of pipe mostly, current in intake pipe are through Semicircular baffle 2 places, conduit upper gas-vapor mix part is become large by the rear flow velocity of Semicircular baffle 2 extruding, at the rear portion of Semicircular baffle 2, form faint vacuum area, make the gentle further separation of water; Gas collects in air collector 3, and a little higher than barometric pressure of pressure makes to manage interior gas overflow by valve 5 standard-sized sheets, in emptying pipe, after air, closes the spillway discharge that minor valve 5 makes to reduce in outlet pipe water.
