Abstract
The utility model relates to a sectional transmission pipe for submergible pumps. A plurality of sections of transmission pipes are installed between a motor and a pump, and the outer part of each section of transmission pipe is provided with a supporting pipe. Both ends of the supporting pipe are provided with a bearing seat and a bearing, and a rotatable transmission shaft is installed between the bearings. Both ends of the transmission shaft are provided with shaft couplings, and a pump housing is connected with the motor through the supporting pipes and a fixing plate. A pump shaft is connected with the transmission shaft and a motor shaft through the shaft couplings. Through the adoption of the utility model, the operational reliability of the existing submergible pump can be increased, the requirements for the manufacturing technique can be lowered, the universality of the product can be enhanced, and transportation, assembly and maintenance for the product become convenient.
Description
The utility model proposes a kind of segmented Under Water Pumps transmission tube that existing Under Water Pumps major axis is made improvements.
Pump and motor can be divided three classes substantially according to its mounting type: first pump and motor all are placed in the conventional pump on the liquid level, it two is that pump and motor all are placed in the submersible pump under the liquid level, and it three is that pump is placed under the liquid level and the Under Water Pumps of motor on liquid level.The advantage of conventional pump is the influence that motor and driving component are not subjected to medium, and its shortcoming is that each primer pump all earlier will diversion in pump, otherwise pump can't proper functioning, and pump also need have the better seal performance in addition, in order to avoid medium leaks.Submersible pump has then overcome the above-mentioned shortcoming of conventional pump, do not need diversion during startup, seal request to pump is not high yet, but its disadvantage is a motor places medium, need sealing reliably, in case sealing system breaks down, then can damage whole motor, therefore in being arranged, the medium of corrosion generally all can not use submersible pump.Under Water Pumps has the above-mentioned advantage of conventional pump and submersible pump concurrently, do not need diversion, it is convenient to start, seal request is not high, medium can not leak, and motor is not subjected to medium influence etc., but its disadvantage is to need the major axis of one of processing in going up to motor down to pump, come transmitted power by this root major axis, the technological requirement of processing slim axle is very high, and quality also is difficult to guarantee, in case be subjected to material, heat treatment, processing mode and the assembling, transportation, the influence of factors such as use, major axis occurs bending and deformation, and Under Water Pumps is cisco unity malfunction soon then, particularly when the degree of depth under the liquid is big, major axis will reach seven, eight meters, contradiction will be more outstanding.
The purpose of this utility model is: keep the existing advantage of Under Water Pumps, overcome above-mentioned shortcoming, increase functional reliability, reduce manufacture process requirement, improve the product versatility, be convenient to transportation, assembling and maintenance.
Technical solution of the present utility model:
The plurality of sections transmission tube is housed between motor and pump, the outside of every section transmission tube is a support tube, two ends at support tube are equipped with bearing support and bearing, a rotating transmission shaft is housed between bearing, transmission shaft two ends are equipped with coupling, pump case connects with motor with fixed plate by support tube, and pump shaft connects with motor reel with transmission shaft by coupling.The stage casing of transmission shaft is a hollow structure, the sealing of two ends.
The utility model compared with prior art has following obvious advantage: the first, because every section transmission shaft is corresponding shorter, and all has the bearings independent operation, therefore be difficult for producing excessive bending deflection, thereby increased reliability of products and working life; The second, owing to replaced an original major axis, reduced the manufacturing process difficulty widely with the short transmission shaft of plurality of sections; The 3rd, since can be pump, motor and fixed plate are processed respectively and are assembled into parts, mix the product that corresponding transmission tube can be formed needs according to the degree of depth under the liquid of customer requirements, improved the versatility of parts in addition, brought great convenience for makers' production; The 4th, owing to can be divided into several parts to product, provide convenience to packed and transported, also help the user's maintenance from now on and the replacing of other parts.
Accompanying drawing is an example structure schematic representation of the present utility model.
Further specify technical solution of the present utility model below in conjunction with accompanying drawing:
Motor and support 1 are installed on the fixed plate 2, its structure and prior art are basic identical, support tube 3 two ends are equipped with bearing support 6 and bearing 5, transmission shaft 4 is housed between two bearings, transmission shaft two ends are equipped with coupling 8 respectively, coupling and transmission shaft relative fixed, and can rotate flexibly around bearing, the length of support tube and transmission shaft are roughly suitable, and support tube, bearing support, bearing, transmission shaft and coupling are formed one section independently transmission tube like this.Utilize the flange of support tube end face bolt to connect with fixed plate, pump 9 respectively during assembling, if any several sections transmission tubes, also relying on flange and Bolt Connection between them, is to have adopted two sections transmission tubes shown in the accompanying drawing, also should make the upper and lower aligning of coupling when end face connects.For the ease of assembling, available claw coupling or pin coupler, bearing can adopt rolling bearing also can adopt sliding bearing, and the length of every section transmission tube is appropriate between 1.5-2.5 meters, quantity is no more than three sections, the same prior art of connecting mode of drain pipe 7 and pump and fixed plate.Because the deadweight of transmission shaft itself can produce downward axial force, influence the working life of bearing, for overcoming this axial force, the stage casing of transmission shaft can be made of hollow tubular, two ends seal, its mode both can adopt mechanical end face seal, also can adopt welded seal, two ends of Hollow Transmission Shafts still are equipped with bearing and coupling as shown in drawings, can produce buoyancy upwards like this when Hollow Transmission Shafts immerses liquid, the size of design hollow tubular should make buoyancy and gravity roughly suitable according to the proportion of liquid.When if liquid level height can produce lifting greatly in actual use, the fluid injection in support tube of should taking measures, to keep necessary buoyancy, the fluid injection mode can be with a tubule UNICOM between drain pipe and support tube, utilize the pressure in the drain pipe to come fluid injection in support tube, also can adopt other power to come fluid injection.
