Definitions
- the invention relates to a releasable connection between two or more housing parts of a centrifugal pump made of metal, in particular between the half shells of a pump housing of a submersible pump, flange-like projections provided on the circumference of the housing parts be braced together.
- centrifugal pumps The design of the housing of centrifugal pumps largely depends on for what purpose and under what conditions the pumps are used become. Repairs and maintenance work that becomes necessary from time to time can also play a role here. Exemplary here are the submersible pumps, who work both submerged and partially submerged and which are often serviced and repaired in harsh operating conditions have to.
- a submersible pump forms an aggregate that essentially consists of one Hydraulic unit and a motor unit. If necessary, there is also a Cooling jacket provided, which ensures adequate heat dissipation from the engine the partially submersible submersible pump ensures.
- Submersible pumps in most cases for pumping liquids must be used, which are interspersed with impurities, especially those Hydraulic unit can be designed so that it can be opened and closed with little effort close so maintenance work in the hydraulic room of the pump is easy Disassembly and assembly work can be carried out.
- the invention has for its object a releasable connection of the beginning to create the type mentioned, the assembly and disassembly of housing parts a centrifugal pump and thus improve the ease of maintenance contributes.
- each in its contour an intermediate ring adapted to a clamp is attached, the at least at one point of its circumference, open clamps placed around the intermediate rings is provided with two legs opening towards its axis, which embrace the intermediate rings, and the two in an open position of the
- the ends of the clamp formed by a fastener are connected to one another are by means of which the distance between the two ends for the purpose of Closing and releasing the connection is changeable.
- the flange-like projections of the housing parts to be connected to one another do not require any special processing, which means the raising of funds for the Establish a detachable connection.
- the one with a screwing too actuating clamping device or with a quick clamping device Closing clamp is quick and easy to open and remove and can be placed on the intermediate rings just as quickly and easily be tensioned again to establish a secure connection.
- the intermediate rings are made of plastic. Another benefit arises when a such an intermediate ring is made in one piece with a housing part, which from its conception, the metal ones to be connected Encloses housing parts at least partially. For example, here is on an inlet strainer, which also serves as the base of a pump unit can, and to think of a cooling jacket for the motor of the pump set.
- connection according to the invention is very well suited for housing parts Sheet. Above all, it has special advantages for housings in which sheet metal and Plastic elements are combined. From those shown above Design options can be a variety of Combinations of housing parts made of different materials and different Create a mold using a modular system.
- FIG. 1 In the variant shown in Fig. 1, three are made of sheet metal Housing parts of a submersible pump connected together. With these Housing parts are the upper shell 1 and the lower shell 2 a pump housing and the foot 3 serving as an inlet strainer at the same time Submersible pump. On the flange-like projections 4 of the housing parts 1 to 3 are intermediate rings 5 made of plastic placed on both sides.
- the two intermediate rings 5 form a conical flange with a height h, one Angle ⁇ and a back width b. They are enclosed by a clamp 6 and centered.
- the clamp 6 is made of sheet metal, it can be optionally be made in one or more parts.
- Hydraulic housing 7 made of plastic is provided.
- FIG. 2 there is a closure 8 in the opening area of the tensioning bracket 6 arranged, which consists essentially of two ends 9 of the clamping ring 6 welded bushings 10, one rotatably arranged in the bushings 10 Screw 11 and a nut 12 is made.
- a closure 8 By tightening the so formed Screw cap is the clamp 6 with a tight fit Connection between the housing parts 1 to 3 ensuring force.
- two housing parts 1 made of sheet metal are used and 13, which enclose a hydraulic housing 7, releasably connected to one another by a clamping concept that corresponds to that of FIG. 1.
- a lower intermediate ring 14 is used here, which is integral with a housing part formed as a pump base 15 and made of plastic connected is.
- FIG. 4 corresponds in principle to the releasable connection of the Fig. 1.
- the peculiarity here is that in addition to that already in the execution of the Fig. 3 used, consisting of intermediate ring 14 and 15 pump base Plastic rope in one piece with an intermediate ring 16 connected housing part, a pump jacket 17 is used.
