Technical Field

The invention relates to the field of water pump assemblies, in particular to a buffer pump bottom with a pressure cavity.

Background

Technical parameters of water pump performance have flow, suction lift, shaft power, water power and efficiency etc., and water pump service environment is complicated, and the medium that bears, flow, operating pressure ambiguity to lead to the water pump to cause the damage in the use, thereby influence production, maintenance scheduling problem, the current water pump accessory in the existing market is processing not inconvenient user and is wasing it, has caused the user and need consume too much time when wasing the water pump accessory.

Disclosure of Invention

The purpose of the invention is: overcome not enough among the prior art, provide at bottom of a band pressure chamber buffer pump, can bear certain pressure under the complex environment at the bottom of this pump, reduce the medium to the inside washing away of water pump and the water pump inner part that leads to damages, impurity in the filter medium that also can be fine to and in the filtration and the medium from the foam of taking, it is convenient to dismantle, the inner part is removable, is fit for extensively using.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

at the bottom of the cushion pump with pressure cavity, its characterized in that: the device comprises a shell and an inner part, wherein the shell is connected with a seal head through an inlet connecting pipe, the seal head is connected with a lower cylinder body, a flange is welded at the upper end of the lower cylinder body, the flange is welded at the lower end of an upper cylinder body, and the upper cylinder body is connected with the flange of the lower cylinder body through a fastener; the inner part is fixed in the lower barrel body through a rib plate by an anti-impact stop block.

Furthermore, rifling lines in the inlet connecting pipe can reduce the flow speed when the medium enters, and the buffering effect is achieved.

Furthermore, the back of the anti-impact stop block is in a smooth arc shape, so that the medium is prevented from being deposited on the back of the anti-impact stop block when the water pump stops working.

Furthermore, go up the inside filtration system who places of stack shell, can play fine filter medium effect, prevent that impurity from causing internals to damage in getting into the water pump, also can play the cushioning effect.

Furthermore, the silk screen demister arranged inside the upper barrel body can remove floating foam, water mist and the like in a medium and also can play a role in buffering.

Furthermore, the pore plate arranged on the lower end face of the filtering system can enable the medium to uniformly penetrate through the filtering system, so that the filtering system can better play a role in filtering and can also play a role in buffering.

Furthermore, filtration system the silk screen demister passes through the fastener chucking by last dog and lower dog and is in go up barrel inner wall, can change the inner part through dismantling the fastener, improved the maintenance convenience.

The technical scheme adopted by the invention has the beneficial effects that:

the parts of the invention are basically combined by metal pipe fittings, flanges and other parts, the structure is simple, the production cost is low, certain pressure resistance is realized, impurities can be filtered, foams can be removed, internal parts can be disassembled for maintenance and cleaning, and the service life is prolonged.

Detailed Description

The invention is further described with reference to the following detailed description and the accompanying drawings.

Referring to fig. 1, there is provided a cushion pump bottom with pressure chamber, the device comprises an outer casing and an inner component,

the shell is formed by welding an inlet connecting pipe 1 with rifling grains 1-1 inside on the top of an end enclosure 2, welding the end enclosure 2 with a lower barrel body 3, welding a flange 6 at the upper end of the lower barrel body 3, welding the flange 6 at the lower end of an upper barrel body 10, and connecting the upper barrel body 10 with the flange 6 of the lower barrel body 3 through a fastener and a gasket to form a complete shell; the inner part is fixed in the lower barrel body 3 through a baffle plate 5 by an anti-impact baffle 4, the back of the anti-impact baffle is a smooth arc surface 4-1, a filtering system 8 is arranged in the upper cylinder body 10, a pore plate 7 is arranged at the lower end of the upper cylinder body 10, a wire mesh demister 9 is arranged at the upper end of the upper cylinder body 10, a detachable stop block 8-1 is arranged at the lower ends of the filtering system 8 and the wire mesh demister, a fixed stop block 8-2 is arranged at the rear end, the filtering system 8 and the wire mesh demister 9 are clamped in the upper cylinder body 10 through screws and gaskets, the diameter of the outer circle of the filtering system 8 and the outer circle of the silk screen demister 9 is smaller than the inner diameter of the upper barrel body 10, the filtering system and the silk screen demister can be taken out conveniently during disassembly, the outer part and the inner part are made of stainless steel, the acid and alkali resistance is improved, the corrosion resistance can be realized, the effects of various media can be realized, and the complete buffer pump bottom with the pressure cavity is formed.

At the bottom of this take pressure chamber buffer pump, can bear the use of overwhelming medium, can prevent that in use from being because of the medium velocity of flow, the temperature, pressure difference and producing the damage to the pump body, take over into to erode to the scour prevention dog when the medium from the entry and eliminate the power, also play the cushioning effect equally when the medium flows in the orifice plate, then evenly flow in filtration system, filter the impurity in the medium, prevent to damage pump internals, rethread silk screen demister, filter in the medium froth entering pump, the flange of this equipment accessible stack shell is disassembled, demolish detachable dog and just can maintain internal components, change, high convenience and fastness, increase of service life, all can use under many circumstances, the production cost is reduced, moreover, the steam generator is simple in structure, and convenient for operation.
