Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to shown in Fig. 1 and 2, it it is a preferred embodiment of the present invention, the pump end face wearing plate device of wear compensation of the present embodiment includes wearing plate 1, wedge 2 and push rod 3, wearing plate 1 has elasticity and is arranged between the pump housing 4 and pump cover 5, wedge 2 is arranged in the cavity volume between pump cover 5 and wearing plate 1, and push rod 3 is arranged on pump cover 5.Wearing plate 1 is arranged between the pump housing 4 and pump cover 5 and the pump housing 4 can be carried out end face seal.In the present embodiment, the pump housing 4 is the pump housing of impeller pump, and wearing plate 1 carries out end face seal to the rotor (not shown) installed in the pump housing 4.
Wearing plate 1 includes that bearing course 11, rubber layer 12 and wearing layer 13, bearing course 11 and wearing layer 13 are all separately fixed on the two sides of rubber layer 12, and bearing course 11 is arranged in the cavity volume of pump cover 5, and wearing layer 13 is arranged on the port part of the pump housing 4.In the present embodiment, for preventing bearing course 11 and wearing layer 13 from coming off, bearing course 11 and wearing layer 13 are fixed on rubber layer 12 by rubber layer 12 vulcanization, it is ensured that bonding between bearing course 11 and wearing layer 13 with rubber layer 12 has sufficient intensity.Rubber layer 12 is arranged between the pump housing 4 and pump cover 5, plays the effect of auxiliary seal.
The upper end 21 of wedge 2 is more than lower end 22, and wedge 2 can slide up and down.Bearing course 11 contacts with wedge 2, and bearing course 11 can reduce resistance when wedge 2 slides.Wedge 2 and the side that bearing course 11 contacts are plane and parallel with the glide direction of wedge 2, and its opposite side is the inclined-plane tilted to lower end 22 from upper end 21 and contacts with pump cover 5.
Pump cover 5 is provided with perforation 51 and push rod 3, push rod 3 is arranged in perforation 51, push rod 3 front end is pressed on the upper end 21 of wedge 2 through perforation 51, regulation push rod 3 makes its front end move down, drive wedge 2 also slide downward, lateral compression wearing plate 1 during wedge 2 slide downward so that rubber layer 12 occurs elastic deformation, and forces wearing layer 13 to the pump housing 4 direction shifted laterally.Refer to shown in Fig. 3.Because being provided with rotor in the pump housing 4, wearing layer 13 namely reduces the gap between wearing layer 13 and rotor to the pump housing 4 direction shifted laterally, reduces the end clearance leakage occurred because this gap is big.Reach to improve the efficiency of pump, extend the purpose in the service life of pump.
Rubber layer 12 to have enough elasticity, it is ensured that occurring not rupture during elastic deformation, the thickness of rubber layer 12 and the selection of material are the most crucial.The thickness of rubber layer 12 is typically at 0.5mm ~ 4.0mm, and the material of rubber layer 12 can be typically the synthetic rubber such as nitrile rubber, fluorubber and polyurethane rubber.In the present embodiment, rubber layer 12 uses polyurethane rubber, and thickness is 1.5mm.
Slide for the ease of wedge 2, be provided with ball 6 in the front end of push rod 3.Being provided with counterbore 23 in the upper end 21 of wedge 2, the front end of push rod 3 is positioned at counterbore 23.When regulating push rod 3 and driving wedge 2 slide downward, wedge 2 will be to wearing plate 1 shifted laterally, and ball 6 can reduce the push rod 3 resistance to wedge 2 shifted laterally.In the present embodiment, controlling the descending depth of push rod 3 for the ease of regulation, push rod 3 is adjusting screw rod, is additionally provided with locking nut 7 on adjusting screw rod, and perforation 51 is screwed hole.When needs regulation push rod 3, first unclamp locking nut 7, then, after rotating push rod 3 to the degree of depth needed, then screw locking nut 7 so that the position of push rod 3 remains stationary as.On the other hand, for the ease of regulating the sliding position of wedge 2, wedge 2 needs upward sliding to reset, and is additionally provided with compression spring 8 in the lower end 22 of wedge 2.When needing, unclamping push rod 3, wedge 2 can upwards reset to initial position under the effect of compression spring 8 elastic force.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
