Abstract

The utility model relates to a modified flexible pipe pump, which comprises a casing, an over-current flexible pipe, a rotor, a positive roller and a side guide roller which are arranged on the outer circumference of the rotor. The utility model is characterized by that an integral sealing structure is employed, the over-current flexible pipe, the rotor, the positive roller and the side roller are all arranged in the sealing cavity formed by the casing, and lubricating cooling liquid is filled in the sealing cavity. Compared with a water cooling structure in the prior art, the service life of the utility model can be improved to more than 50 percent and economize water resource.

Description

The modified model peristaltic pump

The utility model relates to the positive displacement pump class.More particularly, be a kind of peristaltic pump.

Peristaltic pump with its do not leak, suction capacity is strong, self cleaning, exclusive characteristic such as simple in structure, easy to maintenance, is widely used in multiple industries such as chemical industry, oil, medicine, food, building.This pump can the pump suction contain the fluid of impurity, various fiber and the particle diameter solid particle material oar under 1/4 caliber, and can not produce obstruction.In addition, the fluid of inhaling owing to pump only contacts with sebific duct, so corrosivity and the abrasion medium that can carry rubber pipe can bear.In the actual motion since between pressure roller and rubber hose friction-produced heat, for this heat is shifted out, available technology adopting the shell construction of opening wide.Constantly inject cooling water in the housing that opens wide in the time of operation, the water after the heat absorption flows out from the bottom again.This mode not only needs a large amount of water, and the pump inner member is got rusty, and has had a strong impact on the working life of pump.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and a kind of modified model peristaltic pump is provided, with the working life of conserve water resource, prolongation pump.

The purpose of this utility model is achieved through the following technical solutions:

The utility model comprises housing, and " U " shape overcurrent flexible pipe along the housing madial wall is provided with the rotor of the concentric setting of housing, is positioned at the positive pressure roller and the side deflector roll of rotor periphery.

Structural feature of the present utility model is, adopts the integral sealing structure, and described overcurrent flexible pipe, rotor, positive pressure roller, each member of side deflector roll all are positioned at the seal chamber that is formed by housing, have charged into metalworking coolant in described seal chamber.

Compared with the prior art, the utility model is by adopting all-sealed structure, and in the cavity of its sealing the packing lubrication cooling liquid, periodic replacement.Thereby realize no water cooling, improved more than 50% the working life of product.

Fig. 1 is the utility model structural representation.

The turnover nozzle structure schematic representation that Fig. 2 amplifies for Figure 1A portion.

By the following examples, in conjunction with the accompanying drawings the utility model is further described.

Embodiment:

Referring to Fig. 1, identical with prior art is, present embodiment comprises housing 1, and " U " shape overcurrent flexible pipe 2 along housing 1 madial wall is provided with the rotor 3 of housing 1 concentric setting, is positioned at the positive pressure roller 4 and the side deflector roll 5 of rotor 3 peripheries.

As shown in Figure 1, present embodiment adopts the integral sealing structure, and overcurrent flexible pipe 2, rotor 3, positive pressure roller 4 and side deflector roll 5 each member all are positioned at the seal chamber that is formed by housing 1, have charged into metalworking coolant in seal chamber.This cooling liquid can be industry glycerol or soap lye.In the using process, can regularly replace.

Fig. 1 illustrates, and constitutes the housing 1 of seal chamber, corresponding to overcurrent flexible pipe 2 turnover mouth of pipe places, is provided with straight length 6 at it, is tightly connected by the turnover mouth of pipe and the externally connected pipe 7 of this straight length 6 with overcurrent flexible pipe 2.

Referring to Fig. 2, in the present embodiment, at the turnover mouth of pipe place of overcurrent flexible pipe 2, externally connected pipe 7 is inserted in the overcurrent flexible pipe 2, overcurrent flexible pipe 2 peripheries are to have to push away the pipe clamp 8 that pulls out, and pipe clamp 8 is fixing by the bolt 9 that passes housing straight length 6, and axle envelope 10 is set between pipe clamp 8 bottoms and housing straight length 6.

During operation, overcurrent flexible pipe 2 is flattened, under the positive action of flexible pipe 2 self elasticity and side deflector roll 5 by a pair of positive pressure roller 4 along overcurrent flexible pipe 2 rotation, when flexible pipe 2 recovers shape, produce high vacuum in the pipe, suck fluid, fluid under the mechanical presses of positive pressure roller 4 from managing interior discharge.Thereby finish pumping function.
