Abstract
A coal slurry pump consists of an oil cylinder piston, a coal slurry cylinder piston, a discharge port, a valve B, an upper valve ball, a valve A, a lower valve ball and a feed port. The oil cylinder piston is connected with the coal slurry cylinder piston; the valve A and the valve B are connected with the external end of the coal slurry cylinder piston; the lower valve ball corresponds to the valve A, and the upper valve ball corresponds to the valve B. The feed port is arranged on the external end of the valve A, and the discharge port is arranged on the external end of the valve B. The coal slurry cylinder respectively connected with an oil cylinder piston rod reciprocates under the action of hydraulic oil in the oil cylinder. If one cylinder advances, the other cylinder retreats. The two cylinders circulate to pump out the coal slurry continuously. The coal slurry pump which is provided with a hydraulic system and a pumping system has an electric control system controlled by PLC, safety and reliability, high automation degree, few elements used, a simple circuit, and convenient, reliable and correct operation and use. The coal slurry pump is characterized in reliable work, stable transmission, low noise, a simple and reasonable structure of the feed and discharge valves, an optimized layout, low operation and maintenance cost, good maintainability, etc.
