Interpretation of the Merton Wheel dosing pump blocks and their structural (structural) features

(A) Block diagram of the Milton Metering pump Interpretation of the structure of the Milton Metering pump block and the structure (structure) (2) Structure (structure) of the Milton Metering pump The metering pump consists of a conveyor base part, a pump head part , The motor consists of three parts. Transmission parts driven by the motor worm, through the worm gear, the next sleeve, the power transmitted to the N-shaped shaft. The N-shaped shaft and the eccentric block drive the crank connecting rod mechanism and the cross head to drive the plunger for reciprocating motion; the rotational eccentricity is adjusted by the N-shaped shaft and the stroke adjusting mechanism to adjust the stroke of the plunger so as to adjust the flow rate; The reciprocating motion of the liquid cylinder, suction and discharge valve group alternately open and close, the liquid is continuously inhaled and discharged hydraulic end; pump in the suction stroke, the pump head cavity liquid chamber to form a negative pressure, the suction valve opens, the liquid inflow The cylinder chamber; During the discharge stroke, the movement of the plunger increases the pressure on the liquid, causing the discharge valve to open to drain the liquid. (C) The Merton metering pump characteristics ⒈ superior performance of the pump, which diaphragm metering pump absolutely not leaked, high safety performance, accurate measurement and delivery, the flow rate can range from zero to the maximum can be arbitrarily adjusted, the pressure can often Pressure to the maximum allowable range of arbitrary choice. ⒉ regulation intuitive and clear, stable work, no noise, small size, light weight, easy maintenance, can be used in parallel. ⒊ The pump variety, full performance, suitable for conveying -30 degrees to 450 degrees, the viscosity of 0-800mm / s, the maximum discharge pressure up to 64Mpa, the flow range of 0.1-20000L / h, measurement accuracy of ± 1%. ⒋ According to the process requirements of the pump can be manually adjusted and frequency control flow, but also to achieve remote control and computer automation.
