Description

A kind of desulfurization high-pressure hydraulic pump coupling guard

Technical field

The invention belongs to field of thermal power, particularly to a kind of desulfurization high-pressure hydraulic pump coupling guard.

Background technology

In thermal power generation corporations, most of employing is all steam boiler, and fuel burns in steam boiler, heating boiler In water, water is become the steam of HTHP, steam turbine is driven by steam, steam turbine drives electrical power generators, complete whole Power generation process；The fuel that existing steam boiler adopts mostly is fire coal, with the raising of the requirement to environmental protection for the people, right The emission request of coal-burning boiler is also increasingly stricter, and therefore most coal-burning boiler both increases system for desulfuration and denitration, desulfurization The operation principle of denitrating system is the sulfide producing coal-burning boiler in combustion and nitrogen oxides is urged with desulphurization denitration Agent is reacted, and generates the gas that air is not polluted, then is discharged in air, which reduces coal-burning boiler to air Pollution；Desulphurization system needs utilize water under high pressure, the supply of its water under high pressure is to provide using high-pressure hydraulic pump, ordinary circumstance Under, high-pressure hydraulic pump is in outdoor mounted, and high-pressure hydraulic pump relies on motor to drive, and produces water under high pressure, is pipelined to desulfurization In system；Between motor and high-pressure hydraulic pump, its power is transmitted by shaft coupling, for the guarantor of safety and shaft coupling Shield, is often shrouded to shaft coupling using coupling guard, to avoid due to drenching with rain or outside debris enter in shaft coupling, Damage drive disk assembly；Existing coupling guard using bolt, coupling guard is fixed on the base of shaft coupling bottom mostly, by In in outdoor, the bolt of closed coupling cover gets rusty easily, and shaft coupling is being keeped in repair or is being difficult to shaft coupling when changing Cover is pulled down, or even damages coupling guard, and the maintenance to shaft coupling and replacing increase many troubles.

Content of the invention

The problems referred to above existing for existing desulfurization high-pressure hydraulic pump coupling guard, the present invention proposes a kind of desulfurization water under high pressure Pump coupling guard it is characterised in that: include shaft coupling, side plate, cover plate, flanging, Ka Jiao；It is high that described shaft coupling is arranged on desulfurization Between water pump axle and pump motor axle, desulfurization water under high pressure pump shaft and pump motor axle are linked together；Described side plate peace It is contained in cover plate two ends；Described cover plate is toxoplasm, is made up of thin-walled material, and its section top is arc, and bottom is linear pattern； Described flanging is arranged on two lower ends of cover plate, the bending to outside cover plate；Described Ka Jiao is mounted on below shaft coupling Base on, be Z-shaped structure；Described Ka Jiao has multiple, is arranged symmetrically in outside the flanging of cover plate bottom.

Beneficial effect

The beneficial effects of the present invention is, can be when mounting and dismounting coupling guard it is not necessary to bolt fastens and dismantles Bolt, it is to avoid cause to dismantle difficult problem because bolt gets rusty.

Brief description

Fig. 1 is the structural representation of the present invention

1. shaft coupling, 2. side plate, 3. cover plate, 4. flanging, 5. Ka Jiao.

Specific embodiment

In order to further illustrate technical scheme, in conjunction with the specific embodiment of the brief description present invention；As Fig. 1, selects the steel plate of 2 millimeters of thickness, by its bending archwise, as cover plate 3 in this example；From the shaft coupling that the industry is general As shaft coupling 1；It is fabricated to profile and cover plate 3 section shaped upper part identical tabular from 2 millimeters of steel plate of thickness, as side Plate 2, makes u v notch v at the center of arc position of side plate 2, and the width of its breach is more than the diameter of water pump and motor shaft；In cover The longitudinal length identical steel plate of thickness 2 mm in width 40 mm length and cover plate 3 is selected as flanging 4, this example in the bottom of plate 3 In select two flangings, be separately positioned on outside the bottom of cover plate 3, vertical with the side wall of cover plate 3；It is 30 millimeters from the length of side Angle bar, 40 millimeters of intercepted length, 4 millimeters of outer end throat thickness wherein, 40 millimeters of width, 40 millimeters of length, It is welded on wherein one side outer end of angle bar vertical with this side, direction is contrary with the another side of original angle bar, form z with angle bar Type, as card angle 5, selects 4 card angles 5 in this example, card angle 5 is evenly distributed on cover plate 3 both sides, and upper opening is relatively, will The flanging of cover plate 3 lower end both sides snaps in the enforcement just completing the present invention in card angle 5；During application, cover plate 3 is sleeved on shaft coupling On device 1, two end side panels 2 are located at the two ends of shaft coupling 1, and the breach on side plate 2 is stuck on motor shaft and pump shaft, by two Flanging 4 snaps in card angle 5, is achieved that the installation of coupling guard；During dismounting, two flangings are taken out in card angle 5 it is possible to Complete the dismounting of coupling guard it is no longer necessary to demounting bolt, work easy, time-consuming, improve efficiency.
