What is the working principle of the mortar pump?
The working principle: when the S valve 10 and conveying cylinder 5 is switched on, if the piston 7 in advance, for 1, 2 cylinder closed circuit, the piston 8 is in backward state, the transport cylinder 5 of the mortar in the push effect of the 7 piston, enter S tube valve 10 is pressed to a feed port 14; and at the same time in the piston 8, when the S valve 10 and conveying cylinder 5 is switched on, if the piston 7 in advance, for 1, 2 cylinder closed circuit, the piston 8 is in backward state, the transport cylinder 5 of the mortar in the push effect of the 7 piston S, enter the pipe valve 10 is pressed to the discharge port 14; at the same time in the piston 8, conveying cylinder 6 for inhalation of mortar, send the next pressure. When the piston 7 reaches the end of the stroke, under the action of the control system, the piston 7 and 8 move in reverse direction, that is, the piston 7 retreats and the piston 8 advances.
Mortar pump is a single-stage single suction cantilever centrifugal pump is designed for conveying corrosive medium containing fine particles of the design and development of the pump, the use of steel ultra high molecular weight polyethylene (UHMW-PE) material, the material is the latest generation of the pump with corrosion resistant engineering plastics, its most prominent advantage is in all plastic, it has the most excellent abrasion resistance and impact resistance (especially low-temperature impact resistance). The creep resistance (resistance to environmental stress cracking) and excellent corrosion resistance.
Because of its simple structure, low cost and low price, the mechanical cam type mortar pump has been widely used in the situation where the requirement is not high. Hydraulic drive mortar pump due to the use of hydraulic cylinder drive, the transmission piston stroke can be done relatively long, reversing frequency reduction, so its suction efficiency is higher than the mechanical cam, generally can reach about 80%. Due to the use of hydraulic cylinder drive, the pressure of the delivery cylinder is also easy to improve, and its outlet pressure can be done relatively high.
7, the piston 8 reversing valve at the same time, S 10 also reversing, the movable end and conveying cylinder 6 is 6 cylinder in the mortar conveying push 8 piston, enter S tube valve 10 is pressed into the discharge port 14; at the same time in the piston 7, conveying cylinder 5 inhalation of mortar, sent in preparation for the next step pressure. Thus, the mortar is pressed from the hopper to the conveying pipe, and this process is called pumping".
