Abstract
The utility model discloses a plunger pump which comprises a pump cover, a pump body and a plunger frame. The outer side of the plunger frame is provided with a swash plate, a plurality of plunger holes of the plunger frame are provided with a plunger driven by the swash plate, the pump cover is provided with a lower pressure water inlet pipe and a high pressure water output pipe, the high pressure water outlet pipe is provided with a siphoning installation, a safety valve is arranged between the lower pressure water inlet pipe and the high pressure water outlet pipe, and the safety valve is connected with a microswitch used for cutting off a power supply. The plunger pump has the characteristics that the plunger frame is fixedly connected with the pump body and the pump cover by a bolt, the inner end surface of the pump cover is fixedly provided with at least one convex taper pin, the end surface of the pump body is provided with a concave taper pin hole which is critically matched with the convex taper pin, the pump body is provided with a lower pressure water inlet passage and a high pressure water outlet passage, and a current passage insulating obturating ring is arranged between the inner end surface of the pump cover and the end surface of the pump body. The plunger pump has the advantages that the existing plunger pump removes the locating rim, not only ensures the locating precision, but also lightens the weight of the product, shortens the volume of the product, and lowers the manufacturing cost of the product.
Description
Technical field
The utility model relates to a kind of high-pressure service pump, especially relates to a kind of plunger pump.
Background technique
Existing jetting machine in the world is mainly the plunger type high-pressure washing machine, and its structure is easy to realize the operations involving high pressure under the water lubrication environment.The plunger pump structure is in general roughly the same, mainly comprise pump cover, the pump housing and plunger frame, swash plate is installed in the outside of plunger frame, be provided with the plunger that promotes by swash plate in a plurality of plunger holes of plunger frame, pump cover is provided with low pressure intake pipe and high-pressure outlet, and a siphoning installation is set in the high-pressure outlet, is used to draw washing agent, one safety valve is set between low pressure intake pipe and the high-pressure outlet, and safety valve connects the sensitive switch that is used for cutting off the electricity supply.Existing plunger pump uses the aluminum alloy manufacturing usually, and pump housing operated by rotary motion and adopts three bolts that pump cover and plunger frame are connected and fixed in pump cover, owing to need highly location when mounted, so pump cover is provided with the shirt rim.But weight, volume and the manufacture cost that meeting increase product is set of these shirt rims.
Summary of the invention
The bright technical problem to be solved of the utility model provide a kind of in light weight, volume is little and the plunger pump of low cost of manufacture.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of plunger pump, comprise pump cover, the pump housing and plunger frame, the outside of described plunger frame is equipped with swash plate, be provided with the plunger that promotes by described swash plate in a plurality of plunger holes of described plunger frame, described pump cover is provided with low pressure intake pipe and high-pressure outlet, be provided with siphoning installation in the described high-pressure outlet, be provided with safety valve between described low pressure intake pipe and the described high-pressure outlet, described safety valve is connected with the sensitive switch that is used for cutting off the electricity supply, described plunger frame is connected by screw with the described pump housing and described pump cover, be set with at least one protruding taper pin on the interior edge face of described pump cover, described pump housing end face is provided with the recessed taper pin-hole with the mutual precision-fit of described protruding taper pin, the described pump housing is provided with low pressure intake tunnel and high pressure exhalant canal, is provided with flow channel isolating seal circle between the interior edge face of described pump cover and the described pump housing end face.
Can be set with two protruding taper pins on the interior edge face of described pump cover, described pump housing end face is provided with the recessed taper pin-hole with the mutual precision-fit of described protruding taper pin.
Compared with prior art, advantage of the present utility model is the plunger frame is connected by screw with the pump housing and pump cover, and on the interior edge face of pump cover, fixedly install protruding taper pin, pump housing end face is provided with the recessed taper pin-hole with the mutual precision-fit of protruding taper pin, can remove the shirt rim that existing plunger pump is used to locate, under the prerequisite that guarantees Location accuracy, not only can alleviate the weight of product, dwindle the volume of product, can also reduce the manufacture cost of product; On the interior edge face of pump cover, be set with two protruding taper pins, then can when assembling, have the mistake proofing effect.
