Abstract

It is an object of the invention to provide a kind of flexible pipe pump case, during normal pumped medium, the temperature of the pump housing is effectively reduced, the normal operation of maintained equipment, improve the service life of part, including circumferential leg and rear end cap, there is the bearing block of cannula-like in the middle part of rear end cap, the air vent inside and outside connection rear end cap is offered in the plate face of the rear end cap of described bearing block side.Above-mentioned air vent is opened up, possibility is provided for the air inside and outside flexible pipe pump case is exchanged, in normal work, rotor rotation produces disturbance to the air-flow in housing, the disturbance of so air-flow just promotes the exchange of hot and cold air inside and outside pump chamber, and then reduce temperature in pump case will be right, the temperature of whole housing is also minimized, and the service life of the part such as bearing is extended naturally.

Description

Flexible pipe pump case

Technical field

It is exactly specifically the housing improvement of peristaltic pump the present invention relates to peristaltic pump.

Background technology

Peristaltic pump of the prior art is widely used in the industrial circles such as chemical industry, and its basic structure includes housing and is placed in shell Internal flexible pipe, by main shaft drives rotate rotor field spider drive roller squeezing tube carry out pumped medium, in the course of the work by In the frequent extruding of disk roller and flexible pipe, the temperature in housing is higher, and so too high temperature environment is to bearing, the part of flexible pipe Service life have serious adverse effect, frequently maintenance also result in equipment stop transport and delay the normal production schedule.

The content of the invention

It is an object of the invention to provide a kind of flexible pipe pump case, during normal pumped medium, the temperature of the pump housing has Effect is reduced, the normal operation of maintained equipment, improves the service life of part.

To achieve the above object, present invention employs following technical scheme：A kind of flexible pipe pump case, including circumferential leg and Rear end cap, the bearing block for having cannula-like in the middle part of rear end cap, the company of offering in the plate face of the rear end cap of described bearing block side Air vent inside and outside logical rear end cap.

Opening up for above-mentioned air vent, provides possibility, in normal work for the air inside and outside flexible pipe pump case is exchanged When making, rotor rotation produces disturbance, the disturbance of such air-flow just to promote hot and cold air inside and outside pump chamber in the air-flow in housing Exchange, so reduce temperature in pump case will be right, the temperature of whole housing is also minimized, the service life of the part such as bearing Naturally extended.

Specific embodiment

With reference to shown in Fig. 1 to Fig. 3, a kind of flexible pipe pump case, including circumferential leg 10 and rear end cap 20, in rear end cap 20 There is a bearing block 30 of cannula-like in portion, is offered in connection rear end cap 20 in the plate face of the rear end cap 20 of the described side of bearing block 30 Outer air vent 211.Bearing is passed through from the hole of bearing block 30, and the opening up of air vent 211 makes cold and hot inside and outside flexible pipe pump case Air exchange can normally circulate, and in normal work, rotor rotation produces disturbance, such air-flow to the air-flow in housing Disturbance just promote the exchange of hot and cold air inside and outside pump chamber, and then reduce temperature in pump case will be right, the temperature of whole housing Degree is also minimized, and the service life of the part such as bearing is extended naturally.

Further, the plate face of the rear end cap 20 of the described side of bearing block 30 is included in axial direction interval dislocation arrangement Cell board, there is rebound to connect between adjacent cell board.

Preferably, the cell board on rear end cap 20 includes convex cell board 21, and air vent is offered on convex cell board 21 211.Convex cell board 21 can increase the intensity of rear end cap, inside and outside the connection housing of air vent 211, realize the friendship of hot and cold air Change.

Described convex cell board 21 for sector, the two ends arc-shaped side of the fan-shaped radial direction of convex cell board 21 with it is rear The substrate of end cap 20 arranges in axially spaced-apart, both sides straight flange in the fan-shaped circumferential direction of convex cell board 21 by rebound 40 with The substrate connection of rear end cap 20, offers through hole 41 on rebound 40.The setting of through hole 41 so that the air-flow of enclosure interior has Circumferentially direction flow channels hull outside, while the cold air of hull outside enters along housing along the through hole 41 of opposite side, Along with connection housing inside and outside air vent 211 and convex cell board 21 and bearing block 30 between also have gap 22, such housing Interior temperature mixing is uniform, is conducive to the cooling of the parts such as bearing, flexible pipe.

Extruded or corroded the phenomenon that nuclear energy occurs rupture, the medium in the rear hose of rupture for a long time due to flexible pipe Flow into housing, the bottom of the plate face of rear end cap 20 offers the intercommunicating pore 23 inside and outside connection rear end cap 20, intercommunicating pore 23 and week Postponed linking to the internal face of leg 10.So before hose fracture is undiscovered, the medium in housing can be from rear end cap The intercommunicating pore 23 that the bottom of 20 plate face opens up flows out, and reduces the corrosion to housing, can also be set in the outside of intercommunicating pore 23 The parts such as material collecting box collect leaking medium；Under the normal operating conditions flowed out without medium, intercommunicating pore 23 can also realize shell In vivo, the connection of outer air-flow, reduces the service life of the parts such as the temperature of enclosure interior, extension bearing.

In order to ensure that bearing block 30 has enough intensity, the generally Taper Pipe shape of bearing block 30, periphery is to be kissed with rear end cap 20 The taper of conjunction, endoporus is used to install bearing；Or, bearing block 30 is circular tube shaped, is set between its outer tube wall and rear end cap 20 The reinforcement gusset of right angled triangle also may be used.

In order that the temperature of enclosure interior is uniform, described convex cell board 21 is spaced is evenly arranged in circumferential direction 2-6, the convex cell board 21 that the embodiment shown in figure shows is four.

Designing points of the invention are to realize flexible pipe pump case in circumference by gap 22, air vent 211 and through hole 41 The parts such as the current path on direction, radially, axially three directions so that be efficiently cooled in housing, extension bearing Service life.
