The thickness of filler groove is the 1/50 of diameter of plunger.
Plunger 7 material uses austenitic stainless steel.
This novel practical technology offer one is efficient, corrosion-resistant, No leakage, filler are unlubricated, 0-100% conveying capacity stepless adjustment device accurate, convenient, are a kind of novel conveyer devices, it is adaptable to the full-bodied liquid of microparticle carries.When concrete accelerator conveying operation, provide effective guarantee to using conveyer device durability, construction quality and health of human body.
This utility model is applicable to concrete accelerator conveying, and its volume is little, simple in construction, corrosion-resistant, No leakage, operation are easy to adjust.In concrete accelerator course of conveying, concrete accelerator is made to measure on request, by regulation accurately conveying, steady state accuracy is high, both condensed into the concrete of secret room in having reached relatively short period of time, reduce the waste that comes off, be also prevented effectively from concrete strength and be a greater impact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Fig. 1 ~ 3, this utility model includes motor 1(power drive device), dosing pump 2.Dosing pump 2 includes fluid cylinder 3 and is positioned at the worm screw 4 of fluid cylinder 3, turbine 5, main shaft 6, and turbine 5 is located on main shaft 6, and the upper end of worm screw 4 and motor 1 drive connection, worm screw 4 is in transmission connection with turbine 5, and rotating shaft 6 is also associated with N oblique crank Z 8.
Fluid cylinder 3 left end connects plunger case 9, is provided with plunger 7 in plunger case 9.N oblique crank Z 8 and eccentric block drive toggle and crosshead to be connected with plunger 7.Plunger 7 is slidably connected with plunger case 9.
On the outer circumference surface of plunger 7, circumferentially direction is provided with filler groove 10, is filled with polytetrafluoroethylene packing 11 in filler groove.The width of filler groove 10, less than the axial length of plunger 7, is provided with spacing between end distance plunger 7 two ends, the left and right end face of filler groove 10.The thickness of filler groove 10 is the 1/40 ~ 1/60 of plunger 7 diameter, and the present embodiment is 1/50.
Plunger 7 material uses austenitic stainless steel, and plunger 7 surface is coated with ceramic layer, after refining, wear-resisting, corrosion-resistant.
Polytetrafluoroethylene packing 11；As filler, good seal performance No leakage, wear-resistant, corrosion-resistant, shock resistance, non-stick, high temperature resistant, start steadily, the life-span long.Improve the defects such as easy to wear, the easy leakage of conventional piston cylinder operator.
Work process: motor 1 drives worm screw 4 to rotate, by worm gear 5, lower sleeve, imparts power to N oblique crank Z 8.N oblique crank Z 8 drives toggle and crosshead with eccentric block, drives plunger 7 reciprocating;Regulate Rotational eccentricity by N oblique crank Z 8 and stroke control mechanism and carry out the stroke of pilot plunger 7, thus regulate uninterrupted；Along with the plunger 7 reciprocating motion in fluid cylinder, suction, valve group alternately open and close, and liquid is constantly sucked and discharges fluid end.Changing the reciprocating frequency of stroke or the most reciprocating length of stroke can the purpose of up to regulated fluid conveying capacity.Accurate machining accuracy ensure that each output, and then realizes the delicate metering of transported medium.
Fluid cylinder 3 upper and lower arranges check valve and material inlet and outlet, utilizes motor as power source by mechanical transfer, drives plunger 7 to move back and forth, it is achieved to inhale, arrange conveying.N-type axle 8 realizes convenient, accurate electrodeless regulation by connecting rod.N-type axle 8 realizes the electrodeless accurate regulation of 0-100% conveying capacity.
Plunger 7 surface adds plating pottery, mill sequence processing, adds the packing seal mode of design, effectively avoids plunger 7 and cylinder body 8 direct friction, improve corrosion resistance, service life, it is achieved without revealing work.
