Information

Steam Reciprocating Pump is a liquid conveying machine firstly applied in practical engineering. It belongs to a kind of positive displacement pump. It uses the volume of the working chamber of the steam reciprocating pump body to periodically change to convey liquid and increase its energy. Because the movement of the main working parts of the pump (piston and plunger) is reciprocating, it is called a reciprocating pump. At present, due to the wide application of centrifugal pumps, the application scope of reciprocating pumps has gradually narrowed. However, because the Steam Reciprocating Pump can maintain the flow rate almost unchanged even when the water pressure changes rapidly, the reciprocating pump is still used.

Steam Reciprocating Pump

When the plunger is driven to move to the right by the crank connecting rod mechanism, the internal volume of the pump cylinder gradually increases, the pressure decreases, the water pressure valve 3 at the upper end is pressed and closed, and the water suction valve 4 at the lower end acts on the atmospheric pressure on the suction liquid surface. down and open,
The liquid enters the pump cylinder through the suction pipe until the plunger moves to the top of the right end, and the suction process is completed. When the plunger moves to the left from the apex of the right end, the volume of the pump cylinder gradually decreases, the pressure rises, the water outlet valve is pushed up under pressure, and the suction valve is pressed and closed until the plunger reaches the apex of the left end, thereby discharging the water , enter the pressure water pipe, and complete the water pressure process. In this reciprocating motion, the water is sucked into the pump cylinder from the suction pipe intermittently and uninterruptedly and then discharged from the pressure water pipe. The plunger reciprocates once, and the pump cylinder only sucks and discharges water once. This kind of pump is called a single-acting Steam Reciprocating Pump, also known as a single-acting pump. If the piston reciprocates once, the pump cylinder completes two times of water suction and drainage. This kind of pump is called a double-acting reciprocating pump, also known as a double-acting pump.
The flow of the Steam Reciprocating Pump is related to the stroke of the plunger. If the number of reciprocations of the plunger per unit time is constant, the flow of the metering pump can be changed by adjusting the stroke of the plunger. The metering pump uses a regulator that adjusts the stroke to display the flow. In the automatic dosing system of the water plant, the plunger metering pump can be directly used as the dosing equipment for the coagulant solution. The plunger metering pump is actually a plunger type reciprocating pump whose flow can be adjusted and controlled. The flow rate is adjusted by changing the stroke and the number of reciprocations of the plunger.
