Description
A kind of mechanical high-voltage paint pump belongs to the spraying equipment field, relates to the high pressure paint pump.
The structural representation of known a kind of high pressure paint pump is seen Fig. 3, (implication sees description of drawings for details among the figure) shown in Figure 4.Fig. 3 be the A of Fig. 4 to view, mainly illustrate plunger rod 66, cylinder body 45 follow flange 42 with oneself center along S
1When direction is rotated, serve as that axle is finished M with bearing pin center, bottom 59
1Swing shown in the direction, and plunger rod 66 is N simultaneously
1The signal that pumps shown in the direction (plunger rod is done periodically compound motion), L
1And R
1Represent that with double dot dash line flange rotates the arbitrary position of rear pillar stopper rod, 41 is the crankshaft on the flange.Part, structure identical among Fig. 3, Fig. 4 are represented with identical sequence number.Fig. 4 is the C-C sectional view of Fig. 3, illustrates its internal structure.Flange 42; Crankshaft 41; Power source 43; Gland assembly 44G comprises gland 44, black box 46G (comprising foundation ring, V-type sealing cowleather ring, V-type plastic seal ring, Shang Quan); Coating outlet 47; Plunger rod component 66G comprises plunger rod 66, end cap 65, fastening piece 64, packing ring 48,50, black box 49G (comprising foundation ring, V-type sealing cowleather ring, V-type plastic seal ring, Shang Quan), upper valve base 51, ball 52; 63 are the material through hole that is coated with on the plunger rod; Following valve component 56G comprises valve body 56, guide sleeve 53, nut 54, pad 55, lower valve base 57, ball 61, straight pin 62 down; Axle sleeve 60; Bearing pin center 59; Coating import 58.The flange of rotation motion was on top when its deficiency was work, and swinging center is done again with cylinder body when plunger rod is done in cylinder body and moved back and forth up and down and done swing back and forth (being compound motion) with axle center, bottom 59 below.Because plunger rod and cylinder body exist certain interval rather than a rigid body, so the two reaches in the swing process moving, and both center lines are not exclusively on same center line.Through after a while, the situation of Sealing pressurized and wearing and tearing is uneven along its circumference, forms elliptical shape.So just can not guarantee the pump proper functioning, need to change Sealing, cause the increase of maintenance cost, reduce the utilization rate of equipment.
The purpose of this utility model provides a kind of mechanical high-voltage paint pump, reduces the wearing and tearing of Sealing, reduces the maintenance cost of equipment, improves the utilization rate of equipment.
The utility model is achieved in that sees that (implication sees the description of drawings part for details among the figure for Fig. 1, Fig. 2.) mainly comprise power source, flange, link assembly, piston assembly, plunger rod component, following valve component, the gland assembly, guide cylinder, cylinder body, a kind of mechanical high-voltage paint pump that connection and fastening piece are formed, the lower end that it is characterized in that guide cylinder 25 is connected with the upper end of cylinder body 18 is concentricity, the lower end of cylinder body only is connected with the following valve component 12G that coating enters, the lower end of the connecting rod 32 that its upper end is connected with crankshaft 34 on the flange 4 and the piston assembly 29G of upper end by in guide cylinder, moving back and forth of plunger 24, connecting rod 26, locknut 27 connects, the lower end of connecting rod 32 causes that with allowing the revolution because of flange connecting rod is connected along the piston 29 of bearing pin heart swing by bearing pin 30, the lower end of piston is connected with the upper end of connecting rod 26 by locknut 27, and piston seat 16 is equipped with in the lower end of connecting rod and lower end, black box 17, ball 8, pad 10, the upper end of the plunger rod 24 of valve seat 9 connects.Key of the present utility model is to make the periodicity compound motion that pumps and swing of former plunger rod only to be improved to and pumps.Oval phenomenon relatively evenly, no longer takes place in Sealing pressurized and wearing and tearing on circumference like this, has reduced maintenance cost the working life of just having improved Sealing, has improved the utilization rate of equipment.For this reason, plunger rod can not be directly be connected with crankshaft on the flange, and will increase intermediate piston, guide cylinder, connecting rod and a link that bearing pin is arranged.Upper end at cylinder body connects a concentric guide cylinder, and piston moves back and forth up and down in guide cylinder.And the lower end of piston is connected with the upper end of plunger rod by link again.Piston is connected with the lower end of connecting rod by bearing pin again, and the upper end of connecting rod is connected with crankshaft on the flange again.Finish the connecting rod that has only that moves back and forth up and down and swing (being compound motion) like this, connecting rod can be swung at the bearing pin center on piston.Piston, plunger rod only move back and forth up and down.
The seal ring 28 that stops downward liquid flow is arranged between piston 29 outer walls and guide cylinder 25 inwalls.Having increased seal ring 28 between piston 29 outer walls and guide cylinder inwall enters the bottom, reduces the pollution to the bottom with minimizing top oil, foreign material, other liquid.
The seal ring 22 that stops foreign matter to fall into is arranged between gland 23 inwalls and plunger rod 24 outer walls.Between the outer wall of the inwall of gland 23 and plunger rod 24, be provided with seal ring 22 and be in order to reduce oil, foreign matter and enter in the pump coating produced and pollute and reduce wearing and tearing Sealing.
Have above the ball 8 and can be pressed on spring 7 on the valve seat 9 to ball.There is spring 7 to compress above the ball 8, helps ball stable opening, close when plunger rod is worked, reduce the impact of ball, increased the working life of relevant part and improved the sealing of valve seat and the efficient of pump.
Characteristics of the present utility model: owing to move on the swinging center, plunger rod has only upper and lower moving back and forth, and has reduced inhomogeneous deformation and wearing and tearing on the Sealing circumference, increases the working life of Sealing.Reduce the device maintenance cost, improved capacity utilization.Because having increased seal ring 28,22 reduces oil, other liquid, foreign material and enters in the pump coating produced and pollute the wearing and tearing that reach Sealing.Increase working stability, minimizing impact, minimizing damage parts that spring 7 makes ball 8 on the ball 8, improved sealing.
