Embodiment 1

[0033] The disc pump device of the water ring vacuum pump includes a hoop 1, a hoop fastening mechanism and a wrench 3; the hoop 1 is composed of a front hoop and a rear hoop, and the front hoop and the rear hoop pass through the hoop The hoop fastening mechanism is connected to form a ring, which hoops the water ring vacuum pump; the inner side of the hoop 1 is formed with a slot 101, which is used to cooperate with the protrusion on the bearing of the water ring vacuum pump, so that the hoop 1 will not Sliding relative to the water ring vacuum pump; the wrench 3 is fixedly connected with the hoop 1 .

[0034] In this embodiment, the hoop fastening mechanism includes two hoop bolts 2, which cooperate with the hoop bolts 2, and two hoop bolt holes 102 are formed on the left and right ends of the hoop 1 , by passing the hoop bolt 2 through the hoop bolt hole 102, and then fixing it with a nut or forming a thread in the hoop bolt hole 102, so that the hoop 1 and the water ring ...

Embodiment 2

[0039] Compared with Embodiment 1, this embodiment mainly has the following two points of difference:

[0040] (1) The hoop fastening mechanism includes a hoop hook mechanism and a hoop bolt 2, and the hoop hook mechanism and the hoop bolt 2 are distributed at the left and right ends of the hoop 1; The hoop hook mechanism includes an outer hoop hook 104 formed on the front hoop and an inner hoop hook 105 formed on the rear hoop; matched with the hoop bolt 2, The right end of the hoop 1 is formed with a hoop bolt hole 102; the outer hook 104 of the hoop is matched with the inner hook 105 of the hoop, and at the same time, the hoop bolt 2 is passed through the hoop bolt. The holes 102 are fixed so that the hoop 1 is relatively horizontally fixed to the water ring vacuum pump.

[0041] (2) The front end of the wrench 3 is threaded to match the wrench 3, and the hoop 1 is also formed with a wrench fastening bolt hole 106, and the wrench fastening bolt hole 106 is formed with a th...

Abstract

A pump coiling device of a water ring vacuum pump comprises a hoop, a hoop fastening mechanism and wrenches. The hoop is composed of a front hoop body and a rear hoop body. The front hoop body and the rear hoop body are connected through the hoop fastening mechanism to form a circular ring to hoop the water ring vacuum pump. A clamping groove is formed in the inner side of the hoop and used for being matched with a protrusion on a bearing of the water ring vacuum pump so that the hoop cannot slide relative to the water ring vacuum pump. The wrenches are fixedly connected with the hoop. The pump coiling device can effectively solve the technical problem that daily maintenance of the water ring vacuum pump cannot be achieved through pump coiling by common wrenches.

Description

technical field [0001] The invention relates to a water ring vacuum pump disc pump device. Background technique [0002] The water ring vacuum pump is one of the most important equipment in the coal mine gas drainage system, and its working performance directly affects the mine gas drainage effect and safe and efficient production. [0003] However, after running for a period of time, due to the corrosion of the circulating water quality, the inner surface of the pump casing and the impeller of the water ring vacuum pump will be covered by a hard rust layer. In the event of a small card pump accident, the resistance in the pump body becomes larger at the same time, and there is a danger of twisting the pump shaft and burning the motor. With the increase of production capacity and depth of coal mines, gas control becomes more and more difficult, and the requirements for the capacity and operation stability of water ring vacuum pumps are also getting higher and higher. Due t...
