The following problems are generally existed in the use process of the plunger pump in the hydraulic industry:
1) the plunger pump has precise structure and does not have the condition of normalized disintegration inspection on site.
2) The duration from initial abrasion to failure characteristic in the pump is long, and the pump is seriously damaged when noise and vibration caused by obvious abrasion occur.
3) There is no effective and intuitive spot inspection monitoring means.
Disclosure of Invention
For overcoming the not enough of prior art, the utility model aims at providing a hydraulic pressure plunger pump wearing and tearing monitoring devices, through impurity such as the metal piece in the monitoring pressure release oil, can audio-visual monitoring plunger pump wearing and tearing condition.
In order to achieve the above object, the utility model discloses a following technical scheme realizes:
a hydraulic plunger pump wear monitoring device comprises an outer tube and a central tube, wherein the top end of the outer tube is closed, and the bottom end of the outer tube is closed and fixed by a transparent plate; the central tube is fixed in the outer tube, and the bottom end of the central tube is suspended in the air; forming a cavity between the outer tube and the central tube; the central tube is connected with an oil outlet, and the outer tube is connected with an oil inlet.
The transparent plate is a pressure-resistant glass plate.
The central tube and the outer tube are coaxially arranged.
The oil inlet is arranged at the side upper part of the outer pipe.
The bottom end of the outer pipe is sealed and fixed with a transparent plate through a flange.
The flange be two, the centre gripping is fixed with the transparent plate between two flanges, a flange and outer tube bottom welding.
The top end of the central tube extends out of the outer tube.
The part of the central tube extending out of the outer tube is connected with an oil outlet.
The top end of the central tube is closed.
The central tube is welded with the outer tube.
Compared with the prior art, the beneficial effects of the utility model are that:
the hydraulic plunger pump wear monitoring device is simple and reasonable in structure and low in manufacturing cost, and through oil leakage solid-liquid separation and visualization of the hydraulic plunger pump, visual monitoring of metal fragments and the like of wear of the plunger pump is achieved, timely maintenance of the plunger pump is achieved, and further damage of the pump and sudden equipment failure are avoided. Simultaneously, the annular flow channel that forms between center tube and the outer tube and the settling zone of bottom can avoid metal debris to get into the oil tank and produce secondary pollution with metal debris etc. deposit.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-outer tube 2-central tube 3-transparent plate 4-flange 5-oil inlet 6-oil outlet.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.
Referring to fig. 1, the hydraulic plunger pump wear monitoring device comprises an outer tube 1 and a central tube 2, wherein the top end of the outer tube 1 is closed, and the bottom end of the outer tube is closed and fixed by a transparent plate 3; the central tube 2 is fixed in the outer tube 1, and the bottom end of the central tube 2 is suspended in the air; a cavity is formed between the outer pipe 1 and the central pipe 2; the central tube 2 is connected with an oil outlet 6, and the outer tube 1 is connected with an oil inlet 5.
Wherein, the transparent plate 3 is a pressure-resistant glass plate, which is convenient for external observation. For easy to assemble, the top end of the central tube 2 extends out of the outer tube 1, and the central tube 2 is welded with the outer tube 1. The part of the central tube 2 extending out of the outer tube can be connected with an oil outlet 6. In addition, the top end of the central tube 2 can be closed.
The upper part of the outer pipe 1 side is connected with an oil inlet 5, an annular flow passage is formed between the outer pipe 1 and the central pipe 2, and a settling zone is formed between the bottom of the central pipe 2 and the bottom of the outer pipe 1. The central tube 2 and the outer tube 1 are coaxially arranged, so that the annular flow passage is uniform.
The bottom end of the outer tube 1 is sealed and fixed with a transparent plate through a flange 4. Specifically, the flange 4 is two, and the centre gripping is fixed with transparent plate 3 between two flanges 4, and two flanges 4 accessible bolt fastening, a flange 4 and 1 bottom welding of outer tube.
The leakage oil changes the local flow direction of the oil flow at the annular flow passage, and the oil flow velocity is reduced by forming the annular flow passage between the outer pipe 1 and the central pipe 2 to increase the flow area of the oil flow, and the flow velocity of the oil flow at the position can be rapidly slowed down. Borrow this inside when wearing and tearing appear of plunger pump, impurity such as metal piece through this device after under the action of gravity, deposit in the settling zone, sink on the transparent plate 3 of bottom. While the oil flow will enter the central tube 2 and flow out of the oil outlet 6. If the discovery has the metal piece to deposit on the sight glass in-process is patrolled and examined in the routine maintenance, show promptly that the plunger pump has appeared unusual wearing and tearing, need maintain it, can in time avoid the further damage and the equipment proruption trouble of pump to take place, avoided impurity such as metal piece to get into the oil tank simultaneously and produced secondary pollution, can greatly promote the maintenance and the state monitoring technology level of hydraulic plunger pump.
