Abstract
The utility model discloses a two-purposed pump for power spraying and rinsing ceramic plungers without butter, including a piston crank device, a low pressure fluid inlet, a high pressure fluid outlet, and a plenum chamber between the low pressure fluid inlet and the high pressure fluid outlet. The piston crank device provided with a plunger can perform to-and-fro movement in the plenum chamber. Outside of the plunger is supplied with a tightening group and a counterpoise spring. The utility model availing circulation of the backwater interior the product to lubricate the piston device has the advantages of usableness, long life, and low manufacturing cost or the like.
Description
Technical field
It is the mechanical device of fluid pressure with power transfer that the utility model relates to a kind of.
Background technique
At present, two-purpose pump is cleaned in existing spraying, and it comprises pumping chamber between piston crank device, low pressure liquid sucting port, high pressure liquid outlet and low pressure liquid sucting port, the high pressure liquid outlet, the piston crank device moves back and forth in the pumping chamber, this pump exists quick abrasion, working life short and will be at the yellow grease of per hour annotating a lubricate, use and to readjust the V packing in 50 hours, remedy wearing clearance, prevent to leak, guarantee effective drawing liquid efficient, time-consuming fragile again.
Summary of the invention
Main purpose of the present utility model provides a kind of piston sealing device fastening force and can compensate automatically, does not clean two-purpose pump thereby the ceramic plunger that has prolonged working life has the butter power spray.
Another purpose of the present utility model provides a kind of inner backwater circulation of product of utilizing and comes the ceramic plunger of lube pistons device not have butter power spray cleaning two-purpose pump.
For achieving the above object, technical solution adopted in the utility model is: a kind of ceramic plunger does not have the butter power spray and cleans two-purpose pump, it comprises piston crank device, low pressure liquid sucting port, high pressure liquid outlet and the pumping chamber between low pressure liquid sucting port, high pressure liquid outlet, the piston crank device moves back and forth in the pumping chamber, the piston crank device is provided with plunger, and plunger also is equipped with packing group and counterbalance spring outward.
Also have the water lubrication liquid entering hole on the sidewall of pumping chamber, the opening of water lubrication liquid entering hole just in time is positioned at the plunger present position, and the outlet of water lubrication liquid entering hole is connected with the high pressure liquid outlet.
Compared with prior art, because the sealing of the V packing Sealing of the utility model design is to utilize spring tension to make V packing effective deformation, continue wearing and tearing are compensated automatically, often manually the trouble of school accent is real to substitute existing product, has prolonged working life simultaneously; The inner own backwater circulation of product of can also utilizing the utility model satisfies frequent reciprocal the lubricating of plunger, has substituted the prior art employing and has per hour injected loaded down with trivial details that butter lubricates; And the utility model adopts the aluminium oxide ceramics plunger with superperformance, makes performances such as product is wear-resisting, corrosion-resistant improve 15-20 doubly, is particularly useful for the powdered mixing material; The utility model has not only reduced the product cost, has also improved working life.
Description of drawings
The structural representation that does not have butter power spray cleaning two-purpose pump for the utility model ceramic plunger shown in the drawings.
Embodiment
Ceramic plunger shown in the drawings does not have the butter power spray and cleans two-purpose pump, be by piston crank device 1, low pressure liquid sucting port 2, high pressure liquid outlet 3 and the pumping chamber 4 between low pressure liquid sucting port 2, high pressure liquid outlet 3, the inlet of low pressure liquid sucting port 2, high pressure liquid outlet 3 is equipped with one-way valve 9, piston crank device 1 is provided with plunger 7, plunger 7 outer packing group 5 and the counterbalance springs 6 of also being equipped with.Motor motive force passes to belt pulley by the form of rotation, and belt pulley drives piston crank device 1 and moves back and forth in pumping chamber 4, through the two-step supercharging of two one-way valves 9, makes and sprays thing in the high pressure liquid outlet 3 and can reach high pressure.
Also have water lubrication liquid entering hole 8 on the sidewall of pumping chamber 4, the opening of water lubrication liquid entering hole 8 just in time is positioned at plunger 7 present positions, and the outlet of water lubrication liquid entering hole 8 is connected with high pressure liquid outlet 3.Make the direct lube pistons of inner loop water system.
The material of plunger 7 is an aluminium oxide ceramics.Make product wear-resisting, corrosion resistant.
