Abstract
The utility model discloses a bidirectional fastening type connecting structure for a pump head of a slush pump. The bidirectional fastening type connecting structure for the pump head of the slush pump comprises a pump head 5, a pump body 6, a forward bolt 7, a cylinder cover 8 and a reverse bolt 9 arranged on the internal end face 6-1 of a pump body, wherein the forward bolt 7 penetrates through the cylinder cover 8 and the pump head 5 in sequence, the pump head 5 is installed on the pump body 6, the reverse bolt 9 penetrates through the pump body 6, and the pump body 6 and the pump head 5 are connected. According to the bidirectional fastening type connecting structure for the pump head of the slush pump, the reverse bolt which is used for connecting the pump head with the pump body is additionally arranged on the internal end face of the pump body, pump heads can be connected more safely and more reliably, and the load borne by each bolt during drainage is reduced.
Description
Technical field
The utility model relates to the pump head linkage structure of piston high-density pump, particularly a kind of slurry pump head bidirectional fastening formula linkage structure.
Background technique
In address probing industry, the piston high-density pump equipment that is absolutely necessary.Fig. 1～3 are existing slurry pump head linkage structure schematic diagram, include pump head 1, the pump housing 2, bolt 3 and cylinder cap 4, and described bolt 3 runs through cylinder cap 4 and pump head 1 successively, and pump head 1 is arranged on the pump housing 2, and its end does not run through the pump housing 2.
But existing slurry pump head linkage structure has the following disadvantages: when the specifications and models of piston high-density pump are larger, the water displacement that enters in pump head cavity 1-1 also can correspondingly increase, the pressure producing during draining also can correspondingly increase, but be subject to the profile of pump head 1 and the impact of cavity shape, on pump head, installable bolt quantity is limited, during draining, pressure is delivered on bolt 3 by pump head 1 and cylinder cap 4, easily causes even fracture of bolt 3 distortion, affects the general safety performance of slurry pump.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of slurry pump head bidirectional fastening formula linkage structure is provided.This structural safety is reliable, has reduced the load that single bolt is subject to.
The technical solution of the utility model is: a kind of slurry pump head bidirectional fastening formula linkage structure, comprises pump head, the pump housing, forward bolt and cylinder cap; Described forward bolt runs through cylinder cap and pump head successively, and pump head is arranged on the pump housing, also comprises the reverse bolt being located on pump housing interior edge face, and described reverse bolt, through the pump housing, links together the pump housing and pump head.
Compared with prior art, tool has the following advantages the utility model: at pump housing interior edge face, set up for connecting the reverse bolt of pump head and the pump housing, make pump head connect safety and reliability, reduced the load that single bolt is subject to when draining.
Below in conjunction with figure and embodiment, detailed structure of the present utility model is further described.
