Parker Drive Control Pump - DCP Series

By driving and controlling the pump, Parker provides a hydraulic full system solution for speed control, which is pre-set to a predefined range. Therefore, they can provide the advantages of high energy efficiency, reduced noise emissions, and lower component costs.

The drive control pump is basically composed of three components: AC drive unit (frequency controller and electronic equipment), asynchronous or synchronous motor, and hydraulic pump. The pump can be a vane pump - single or multiple designs - or a variable displacement axial piston pump. Drive control pumps can adjust the hydraulic supply at the center of all drives, so they can provide precise power required in the cycle at any time.

The impeller is installed inside the pump casing and fastened to the pump shaft, which is directly driven by the motor. There is a liquid suction tube in the center of the pump casing. The liquid enters the pump through the bottom valve and suction pipe. The liquid discharge port on the pump casing is connected to the discharge pipe.
Before starting the pump, fill the pump casing with the liquid being transported; After starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate along with it. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the snail shell, the liquid slows down due to the gradual expansion of the flow channel, and converts some of its kinetic energy into static pressure energy, which then flows into the discharge pipeline at a higher pressure and is delivered to the required location. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed at the center of the impeller. Due to the pressure above the liquid level in the storage tank being greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. It can be seen that as long as the impeller continues to rotate, the liquid will be continuously sucked in and discharged.
The working principle of a linear pump is different from any other pump. It uses the principle of magnetic levitation and a spiral ring fluid dynamics structure to achieve fluid propulsion, that is, to cancel the shaft, cancel the shaft connection, and cancel the shaft sealing structure. After startup, the current is converted into a magnetic field, which drives the spiral ring to operate, that is, the spiral ring lifts the fluid forward.
performance parameters
There are mainly flow rate and head, as well as shaft power, speed, and necessary cavitation allowance. Flow rate refers to the amount of liquid output through the pump outlet per unit time, generally using volumetric flow rate; Head is the energy increment per unit weight of liquid transported from the pump inlet to the outlet. For positive displacement pumps, the energy increment is mainly due to the increase in pressure energy, so it is usually expressed as pressure increment instead of head. The efficiency of a pump is not an independent performance parameter, it can be calculated from other performance parameters such as flow rate, head, and shaft power using formulas. On the contrary, given the flow rate, head, and efficiency, the shaft power can also be calculated.
Performance curves of four types of pumps
Performance curves of four types of pumps
There is a certain interdependence and variation relationship between the various performance parameters of the pump. By testing the pump, the parameter values can be measured and calculated separately, and plotted as curves to represent them. These curves are called the pump characteristic curves. Each pump has a specific characteristic curve provided by the pump manufacturer. The recommended performance range for the pump is usually indicated on the characteristic curve provided by the factory.
The actual working point of the pump is determined by the intersection of the pump's curve and the pump's device characteristic curve. The selection and use of pumps should ensure that the working point of the pump falls within the working range to ensure operational economy and safety. In addition, when the same pump transports liquids with different viscosities, its characteristic curve will also change. Usually, the characteristic curve provided by pump manufacturers refers to the characteristic curve when delivering clean cold water. For power pumps, as the viscosity of the liquid increases, the head and efficiency decrease, and the shaft power increases. Therefore, in industry, liquids with high viscosity are sometimes heated to reduce viscosity and improve conveying efficiency.
