Abstract
The invention discloses a corrosion-resistant centrifugal pump. The corrosion-resistant centrifugal pump is characterized by comprising a motor, a connecting end cover, a bearing seat, a bearing, a waterstop ring, an impeller nut, a pump body, a water drainage hole, a pump shaft, a coupler, a mechanical seal, an impeller, an air exhausting hole and a pressure-tapping plug, wherein the motor is arranged at the uppermost end of the whole centrifugal pump and directly connected with the water pump to transmit power; the connecting end cover is arranged below the motor and used for protecting the bearing and the waterstop ring; the bearing seat is arranged blow the coupler and connected with the pump shaft; the bearing is arranged under the bearing seat and used for fixing the position of the pump shaft; the waterstop ring is arranged on the pump shaft and prevents the situation that the seal leaks water and then water enters the motor; the impeller nut is arranged at the tail end of the pump shaft and used for fixing the central position of the impeller; and the pump body is arranged on the lower portion of the whole centrifugal pump. The corrosion-resistant centrifugal pump is simple in structure, stable in performance, high in corrosion resistance, low in labor intensity of workers and capable of effectively improving work efficiency.
Description
Technical field
The invention belongs to mechanical, be specifically related to a kind of anticorrosive centrifugal pump.
Background technology
At present, centrifugal pump is a kind of range of application general hydraulic very widely, along with developing rapidly of mining industry, to the demand of centrifugal pump also in continuous increase.In the construction and production process of mine, often have the water come from various channels and pour in mine continuously, affect the safety in production of mine, now must have drainage equipment that the water pouring in mine is drained into ground in time from down-hole, and such a key player just served as by centrifugal pump.But also in that this work bad border can make centrifugal pump body can therefore suffer from corrosion.
Summary of the invention
In order to solve above-mentioned Problems existing, the present invention provides a kind of anticorrosive centrifugal pump.
The present invention is achieved through the following technical solutions:
A kind of anticorrosive centrifugal pump, it is characterised in that: include motor, connect end cap, bearing block, bearing, retaining ring, impeller nut, the pump housing, dewatering orifice, pump shaft, shaft coupling, mechanical seal, impeller, steam vent, pressure plug；Described motor is placed in the top of whole centrifugal pump, is directly connected transmission power with water pump；Described connection end cap is placed in below motor, in order to protect bearing, retaining ring；Described bearing block is placed in the lower section of shaft coupling, is connected with pump shaft；Described bearing is placed in the lower section of bearing block, in order to the position of fixing pump shaft；Described retaining ring is placed on pump shaft, makes motor entering water for preventing sealing from leaking；Described impeller nut is placed in pump the tip of the axis, in order to fixing impeller central position；The described pump housing is placed in the lower section of whole centrifugal pump.
As the further prioritization scheme of the present invention, described dewatering orifice is placed in the lower left of the pump housing；Described pump shaft is coaxially connected with motor；Described shaft coupling is placed between motor and pump shaft；Described mechanical seal is placed in the junction of pump shaft and the pump housing；Described impeller is placed in the middle part of the pump housing.
As the further prioritization scheme of the present invention, described steam vent is placed in the low order end top position of the pump housing, to ensure the normal startup of pump；Described pressure plugs the lower section in steam vent, can install the operation normally and efficiently of Pressure gauge monitoring pump.
Compared with prior art, the invention has the beneficial effects as follows: present configuration is simple, stable performance, resistance to corrosion is strong, and labor strength is low, and can effectively improve work efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
Such as Fig. 1, a kind of anticorrosive centrifugal pump, it is characterised in that: include motor (1), connect end cap (2), bearing block, bearing, retaining ring (3), impeller nut, the pump housing (4), dewatering orifice (5), pump shaft (6), shaft coupling (7), mechanical seal, impeller, steam vent (8), pressure plug (9)；Described motor (1) is placed in the top of whole centrifugal pump, is directly connected transmission power with water pump；Described connection end cap (2) is placed in motor (1) lower section, in order to protect bearing, retaining ring (3)；Described bearing block is placed in the lower section of shaft coupling (7), is connected with pump shaft (6)；Described bearing is placed in the lower section of bearing block, in order to the position of fixing pump shaft (6)；Described retaining ring (3) is placed on pump shaft (6), makes motor entering water for preventing sealing from leaking；Described impeller nut is placed in the end of pump shaft (6), in order to fixing impeller central position；The described pump housing (4) is placed in the lower section of whole centrifugal pump.
Described dewatering orifice (5) is placed in the lower left of the pump housing (4)；Described pump shaft (6) is coaxially connected with motor (1)；Described shaft coupling (7) is placed between motor (1) and pump shaft (6)；Described mechanical seal is placed in the junction of pump shaft (6) and the pump housing (4)；Described impeller is placed in the middle part of the pump housing (4)；Described steam vent (8) is placed in the low order end top position of the pump housing (4), to ensure the normal startup of pump；Described pressure plug (9) is placed in the lower section of steam vent (8), can install the operation normally and efficiently of Pressure gauge monitoring pump.
Centrifugal pump is generally driven by motor, starting before pump, and the pump housing and hydraulically full in suction line.When impeller high speed rotating, impeller drives interlobate liquid to rotate together, and due to the effect of centrifugal force, liquid is thrown toward impeller outer edge kinetic energy from impeller central and is consequently increased.After liquid enters pump case, owing to the runner in volute shaped pump casing expands gradually, flow rate of liquid is gradually lowered, and a part of kinetic energy is changed into static energy, and then liquid flows out along outlet with higher pressure.The liquid of suction line enters in pump under differential pressure action, and impeller does not stop to rotate, and liquid is also continuously inhaled into and extrudes.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
