Abstract
The utility model relates to a radial plunger pump for ejecting and cleaning machine, comprising a pump body cast by aluminum alloy, a plunger, a connecting rod, an off-center axle. A water inlet valve core and a water outlet valve core. The utility model is characterized in that a stainless inlet valve seat and a stainless water outlet valve base are provided in the pump body, and the inlet valve seat, the water outlet valve base and the pump body are connected by a screw. The utility model has the advantages of that the radial plunger pump for ejecting and cleaning machine can increase the valve core impact resistance property of the inlet valve seat and the water outlet valve base of the radial plunger pump, and greatly extend the operational life of the radial plunger pump.
Description
Technical field
The utility model relates to a kind of water pump, particularly a kind of radial plunger pump that is used for jet cleaner.
Background technique
The present radial plunger pump that uses at cleaning industry, water inlet and outlet valve base in its pump housing generally is directly machine shaping on the body of the cast copper of the pump housing, because the radial plunger pump is plunger straight reciprocating motion in valve pocket when work, to finish function to the water pressurization, but in a stroke with the front-rear reciprocation movement of plunger, the water valve valve seat surface all will clash into once with spool, spool produces brinelling to the water inlet and outlet valve base of cast copper, therefore the radial plunger pump is at general work after 200 hours, the valve face sealing of water inlet and outlet valve base is degradation failure, cause the pressure and the discharge capacity of pump to descend, influence the working life of pump.
Summary of the invention
The purpose of this utility model is that to solve radial plunger pump in the prior art existing because of water inlet and outlet valve base and spool bump cause the wear and tear problem of seal failure of valve face, and a kind of radial plunger pump that is used for jet cleaner that can improve the valve seat wear resistance greatly is provided.The utility model is designed for the radial plunger pump of jet cleaner, comprises the pump housing, plunger, connecting rod, eccentrically weighted shaft, water inlet spool, the water outlet spool of aluminium alloy compression casting, it is characterized in that: stainless inlet valve seat, water outlet valve seat are arranged in the pump housing.Inlet valve seat, water outlet valve seat and the pump housing are by being threaded.The utility model has the advantages that the inlet valve seat that can increase the radial plunger pump, the impact of the anti-spool of water outlet valve seat, the operating life that prolongs the radial plunger pump greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
The pump housing 4, plunger 3, connecting rod 2, eccentrically weighted shaft 1, water inlet spool 6, the water outlet spool 5 that comprise aluminium alloy compression casting among the figure, it is characterized in that: the inlet valve seat 7, the water outlet valve seat 8 that have stainless steel to make in the pump housing 4, inlet valve seat 7, water outlet valve seat 8 and the pump housing 4 are by being threaded.In course of working, inlet valve seat 7, water outlet valve seat 8 usefulness that stainless steel is made are threaded onto on the pump housing 4, because stainless intensity is higher, increased the bump of inlet valve seat 7, water outlet valve seat 8 anti-coppers water inlet spools 6, water outlet spool 5, the operating life that can prolong the radial plunger pump greatly.
Claims (2)
1, the radial plunger pump that is used for jet cleaner comprises it is characterized in that the pump housing, plunger, connecting rod, eccentrically weighted shaft, water inlet spool, the water outlet spool of aluminium alloy compression casting: stainless inlet valve seat, water outlet valve seat are arranged in the pump housing.
2, by the described radial plunger pump that is used for jet cleaner of claim 1, it is characterized in that: inlet valve seat, water outlet valve seat and the pump housing are by being threaded.
