Abstract
The invention relates to a sanitary pump provided with a sealing assembly. The sanitary pump provided with the sealing assembly comprises a pump body, an impeller and a spindle, wherein the spindle is sleeved with both the pump body and the impeller, and a spring seat, a spring, a transmission sleeve, the sealing assembly, a movable ring and a static ring are arranged between the impeller and the spindle in sequence. The sanitary pump provided with the sealing assembly is characterized in that the spring is fixed to the spring seat, the spring seat is connected with the movable sleeve in a tooth interlocking mode, the transmission sleeve is in interference connection with the movable ring, the sealing assembly adopts the structure of a V-shaped fabric rubber sealing ring, and the V-shaped fabric rubber sealing ring is composed of a supporting ring, a sealing ring and a compression ring. When the pump body is started, the spindle provides torque for the movable ring through the impeller, the spring seat and the transmission sleeve, and the sealing ring, the compression ring, the spindle and the transmission sleeve keep relatively static. By modifying the sealing structure and adopting the V-shaped fabric rubber sealing ring, the sanitary pump provided with the sealing assembly lowers repairing costs and is reliable in operation; the use range of the centrifugal sanitary pump is widened through improvement of the sealing device.
Description
Technical field
The present invention relates to fine chemistry industry centrifugal sanitary pump, especially a kind of sanitary pump with black box.
Background technique
Centrifugal sanitary pump and liquid comes into contact part all make of stainless steel, this pump easy cleaning, and liquid output amount can regulate arbitrarily, and delivery outlet can be mounted to arbitrarily angled as required and without the need to fixing, be widely used in the industries such as food, medicine, fine chemistry industry.The same with general centrifugal pump, its main working parts is impeller, impeller has the blade of some.The liquid of blade passage produces centrifugal force with rotation, is thrown toward outer rim from the center of impeller, flows in scroll casing shape pump chamber, and flow to exhaust port and export with higher flow velocity.Meanwhile, in pump, be formed centrally certain degree of vacuum, liquid constantly entered pump from suction port, and exports continuously.
At present, mostly the seal form that sanitary pump dispatches from the factory is the mechanical seal of in-built, interior stream, single end face, single spring non-equilibrium structure, sanitary pump as shown in Figure 1, and rotating ring drives by the interference after rubber seal installation, spring seat connects with drive sleeve socket, transmitting torque.After mechanical seal assembly, use hand propulsion rotating ring, should move flexibly on main shaft and have certain elasticity; During with hand rotating spindle, should without lopsided sensation; Main shaft can rotate by any direction.
Under normal circumstances, avoid finding time for a long time as long as install in correct and operating process, the working life of seal arrangement is very long.But when relating to high temperature mucus, seal arrangement damages frequent.High temperature mucus is along with the prolongation of dead time, and in pump, mucus temperature reduces, and have crystalline solid to separate out and be attached on mechanical sealing assembly, dynamic and static ring is cohered, and black box is linked together by cohesion and the pump housing.Pumping up dynamic moment, rubber seal is with main axis, and Adam's apple place produces larger torsion, and wall thickness is thinner herein, and Fraquent start makes it twist off damage very soon.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of sanitary pump with black box.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of sanitary pump with black box, comprise the pump housing, impeller and main shaft, the described pump housing and impeller are all enclosed within main shaft, spring seat is provided with successively between impeller and main shaft, spring, drive sleeve, black box, rotating ring and stationary ring, it is characterized in that: described spring seat is fixed with spring, spring seat connects with drive sleeve dental inlay, described drive sleeve and rotating ring interference fit joint, described black box adopts the structure of V-type fabric rubber seal, V-arrangement fabric rubber seal is by supporting ring, seal ring and pressure ring composition,
When the pump housing starts, main shaft provides moment of torsion by impeller, spring seat and drive sleeve to rotating ring, and seal ring, pressure ring and main shaft and drive sleeve keep geo-stationary.
Further, described pump housing side is fixed with friction top by screw, is provided with pad between described friction top and the pump housing, and the place that friction top bottom contacts with stationary ring is provided with sealing gasket.
Further, described main shaft offers flat key.
The invention has the beneficial effects as follows: the present invention, by transformation sealing configuration, adopts V-type fabric rubber seal, reduces maintenance cost, and reliable, and the using scope of centrifugal sanitary pump has been expanded in the improvement of seal arrangement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing embodiment, the present invention is further described.
