Abstract
The utility model belongs to the technical field of water conservancy engineering machinery, and relates to a slurry pump. The slurry pump comprises an oil cylinder piston and a slurry cylinder piston connected with the oil cylinder piston. The slurry pump is characterized in that the slurry cylinder piston is a polyurethane piston body in which a piston internal core is arranged, and one end of the piston internal core is provided with a connecting hole; the outer end of the slurry cylinder piston is connected with a valve A and a valve B, and an upper valve ball and a lower valve ball are arranged corresponding to the valve A and the valve B. The slurry pump has the beneficial effects of reliable working and stable transmission; the polyurethane piston has abrasion resistance as well as flexibility, and can be used in severe environments; and the slurry pump can bear high pressure and is worthy of popularization and use.
Description
(1) technical field
The utility model belongs to the water engineering machinery technical field, particularly a kind of slurry pump.
(2) background technique
Now, commercially available various slurry pump, the structure that the two ends of generally adopting the material cylinder are connected with hopper with washing chamber's casing respectively is provided with changement in the hopper, a left side is housed respectively on washing chamber's cover plate
Right oil hydraulic cylinder induction position limit switch is because left and right sides oil hydraulic cylinder induction position limit switch on washing chamber's cover plate and left and right sides oil hydraulic cylinder are often having error aspect the installation contraposition, so be easy to cause the breaking-up of pump.And the piston of the slurry pump under the technology is a cylindrical body at present, on cylindrical outer wall, piston ring is arranged, and is connecting end at piston one end, and this connecting end is connected with connecting rod.This mud piston very easily damages when using, and the piston that is connected on the piston outer wall is reciprocating at the piston cylinder inwall of slurry pump, very easily the piston cylinder inwall is destroyed and causes slurry pump to use, and simultaneously, such slurry pump manufacture cost is also very high.
(3) summary of the invention
The utility model is in order to remedy the deficiency of existing technology, a kind of reliable operation is provided, cost is low, efficient is high, do not destroy the slurry pump of piston cylinder inwall.
The utility model is realized through following technological scheme:
A kind of slurry pump comprises oil cylinder piston and the mud cylinder piston that is connected oil cylinder piston, and it is characterized in that: said mud cylinder piston is the polyurethane piston body, is provided with the piston inner core in the polyurethane piston body, and an end of piston inner core offers attachment hole; Mud cylinder piston outer end is connected with valve A and valve B, and corresponding valve A and valve B are respectively arranged with upper valve ball and lower valve ball.
The outer end of said valve A is provided with discharge gate, and the outer end of valve B is provided with material feeding mouth.
The beneficial effect of the utility model is: reliable operation, stable drive, noise is low, the feeding and discharging valve arrangement is succinct, and this polyurethane piston not only has wear resistance but also have pliability, can in rugged environment, use, and the pressure that bears is big, is worth of widely use.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the utility model;
Among the figure, 1 oil cylinder piston, 2 mud cylinder pistons, 3 polyurethane piston bodies, 4 piston inner cores, 5 attachment holes, 6 valve A, 7 valve B, 8 upper valve balls, 9 lower valve balls, 10 discharge gates, 11 material feeding mouths.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises oil cylinder piston 1 and the mud cylinder piston 2 that is connected oil cylinder piston 1, and mud cylinder piston 2 is a polyurethane piston body 3, is provided with piston inner core 4 in the polyurethane piston body 3, and an end of piston inner core 4 offers attachment hole 5; Mud cylinder piston 2 outer ends are connected with valve A6 and valve B7, and corresponding valve A6 and valve B7 are respectively arranged with upper valve ball 8 and lower valve ball 9.The outer end of valve A6 is provided with discharge gate 10, and the outer end of valve B7 is provided with material feeding mouth 11.
Adopt a kind of slurry pump of the utility model, the mud cylinder is connected with the oil cylinder piston bar, under the effect of oil cylinder hydraulic oil, realizes to-and-fro motion.One cylinder advances, and then another cylinder is retreated.Mud cylinder outlet links to each other with upper valve ball 8, lower valve ball 9 usefulness bolts, and retreats upper valve ball 8 whereabouts that cylinder links to each other, and valve A6 closes, lower valve ball 9 risings, and valve B7 opens, and from material feeding mouth 11 mud is sucked the mud cylinder.When piston-advance, clutch release slave cylinder and valve chamber internal pressure rise, and lower valve ball 9 falls, and the lower valve ball 9 among the valve B7 is closed, and upper valve ball 8 rises, and valve A6 opens, and mud cylinder piston 2 pumps by valve A6 mud from discharge gate 10.Outside piston inner core 4, connect polyurethane piston body 3, the diameter in the middle of the polyurethane piston body 3 does not need accurate manufacturing process less than the diameter at two ends; Just can produce polyurethane piston body 3, thereby satisfy mud piston 2 proper functioning, when polyurethane piston body 3 moves in piston cylinder; Good seal is arranged; Because the material of polyurethane than the material softer of piston cylinder, can not pulled the inwall of piston cylinder, has protected the piston cylinder inwall injury-free.
Claims (2)
