Abstract
The utility model relates to a two-screw transport pump for the high thickness medium. The internal part of the pump body liner of the pump casing is provided with two screws; each screw is provided with two sections of threads; the threads on the two ends of the two screws are pairwise engaged; one surface of the pump body and the liner is a liquid inlet, and the other surface is a liquid outlet. The two screws are connected to the bearing in the bearing seats on the two side ends; the same end of the two screws is respectively provided with engaged synchronous gears, and the two ends of each screw are provided with the two end surface mechanical sealing on the internal side near the bearing. The two-screw transport pump for high thickness media has the advantages of small vibration and low noise. Compared with a rotary piston pump, when the high thickness materials are conveyed, the two-screw transport pump for the high thickness medium can reduce the production cost by 40 yuan per hour.
Description
The utility model belongs to the high viscosity medium transfer pump, particularly a kind of twin-screw high viscosity medium transfer pump.
At present, synthetic rubber industry transfer of highly viscous rubber liquid is recognized and is all adopted rotary piston pump.Driving shaft is given a pair of intermeshing cam by synchromesh gear with transmission of power, and at this moment, cam is done relative rotary motion, makes the volume of pump chamber produce cyclically-varying, causes medium to forward outlet to from inlet, reaches the purpose of conveying.Its bearing, gear all adopt interior dress form, lean on the medium of being carried to come lubricating bearings and gear.And full-bodied glue does not generally have lubricity, and therefore, the working life of bearing, mechanical seal is very low, sealing effect is poor, and the rotary-piston revolution speed is lower, can't directly drive by motor, must be by the speed reducer rear driving of slowing down, thereby the noise of pump, vibration are bigger.Again because rotary-piston pump bearing, mechanical seal adopt medium lubricated, therefore, can not be used for directly carrying the glue of viscosity higher, need dilute at course of conveying, yet again solvent extraction is come out with solvent, increased production process and cost of production.Domestic part synthetic rubber plant is when the design production line, once supporting use is the high viscosity medium transfer pump of foreign country excessively, as helical rotor pump and two screw pump, helical rotor pump is because its stator liner material is a rubber, can react with the partial solvent in the synthetic rubber production process and lose efficacy, two screw pump is buried bearing, and single mechanical end face seal makes bearing, the mechanical seal life-span is low and be eliminated.The direct conveying of high viscosity glue becomes the synthetic rubber industry and chases after a difficult problem that is essential and will solves, and existing domestic synthetic rubber industry glue transfer pump is rotary piston pump, and solvent dilution is carried.
The purpose of this utility model provides a kind of twin-screw high viscosity medium transfer pump, overcomes the shortcoming and defect of prior art.
The purpose of this utility model is achieved in that
A kind of twin-screw high viscosity medium transfer pump, it is characterized by: pump housing lining is arranged in pump case, in the pump housing lining two screw rods, active screw rod and driven screw rod, two sections screw threads are respectively arranged on each screw rod, two ends screw thread on two screw rods, be meshed in twos, the pump housing and lining simultaneously are liquid entering holes, the pump housing and lining another side are liquid outlets, the two ends of two screw rods are connected on the bearing in the bearing support of pump housing two side ends, and a screw rod has the spindle nose that connects power for one section, and the same end of its screw rod the other end and another screw rod respectively has the synchromesh gear that is meshed.
Near on the inboard of bearing double mechanical seal is arranged at each screw rod two ends.
Double mechanical seal one side is a sealed letter, and opposite side is a sealing cover, and the seal ring and the seal ring that are sealed on the axle are arranged in it.
The utility model has the advantages that:
Twin-screw high viscosity medium transfer pump has the effect of improving working environment significantly, vibrates for a short time, and noise is low, and than using rotary piston pump transfer of highly viscous material, approximately per hour can reduce production costs 40 yuan.

Fig. 2 is a twin-screw high viscosity medium transfer pump sectional drawing
Fig. 3 is a twin-screw high viscosity medium transfer pump hermetic unit sectional drawing
A kind of twin-screw high viscosity medium transfer pump, pump housing lining 7 is arranged in pump case 9, in the pump housing lining two screw rods, active screw rod 5 and driven screw rod 6, two sections screw threads 10 are respectively arranged on each screw rod, 11,12,13, two ends screw thread on two screw rods, be meshed in twos, the pump housing and lining simultaneously are liquid entering holes 14, the pump housing and lining another side are liquid outlets 15, the two ends of two screw rods are connected on the bearing 1 in the bearing support 2 of pump housing two side ends, and a screw rod has the spindle nose 16 that connects power for one section, and the same end of its screw rod the other end and another screw rod respectively has the synchromesh gear 8 that is meshed.
At each screw rod two ends near adopting general double mechanical seal 3 structures that have on the inboard of bearing, a side sealing letter 4 of double mechanical seal, opposite side is a sealing cover 17, and the seal ring 18 and the seal ring 19 that are sealed on the axle are arranged in it.
