Germany ALLWEILER pump ALLWEILER model ALLWEILER price
ALLWEILER pumps operate by using impeller rotation to induce centrifugal motion in water. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, start the motor to drive the pump shaft, causing the impeller and water to rotate at high speed. The water undergoes centrifugal motion, is thrown toward the outer edge of the impeller, and flows into the discharge pipe of the water pump through the flow channel of the volute casing. The basic structure of an ALLWEILER centrifugal pump consists of six parts: impeller, pump body, pump shaft, bearing, sealing ring, and packing box. 1) The impeller is the core part of the centrifugal pump; its rotational speed
Germany ALLWEILER coupling ALLWEILER model ALLWEILER price
ALLWEILER couplings are mechanical components used to connect two shafts (driving shaft and driven shaft) in different mechanisms, enabling them to rotate together to transmit torque. In high-speed, heavy-load power transmission systems, some couplings also provide buffering, vibration damping, and improved dynamic performance of the shaft system. A coupling consists of two halves, each connected to the driving shaft and the driven shaft respectively. Generally, prime movers are connected to working machines via couplings. Features of ALLWEILER couplings: Due to their simple structure, low cost, and ability to transmit large torques, they are commonly used when rotational speed is low, there is no impact load, shaft rigidity is high
Germany ALLWEILER shaft ALLWEILER model ALLWEILER price
ALLWEILER shafts are used to support rotating components and withstand only bending moments without transmitting torque. Some spindle shafts rotate, such as the axles of railway vehicles, while others do not rotate, such as the shafts supporting pulleys. Depending on whether the shaft rotates during operation, spindle shafts can be divided into rotating spindle shafts and fixed spindle shafts. Rotating spindle shaft: The shaft withstands bending moments during operation and rotates. Fixed spindle shaft: The shaft withstands bending moments during operation and remains stationary. Based on the function of the shaft and the loads it withstands, shafts can be classified into spindle shafts, rotating shafts, and transmission shafts: Spindle shaft: Withstands only bending moments without transmitting torque; Rotating shaft: Withstands both
German ALLWEILER seals ALLWEILER models ALLWEILER prices
ALLWEILER seals are sealing devices installed to prevent leakage between the pump shaft and the casing. Common types of shaft seals include packing seals, mechanical seals, and dynamic seals. The shaft seal of a reciprocating pump is usually a packing seal. When transporting media where leakage is not permitted, a diaphragm reciprocating pump can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly include packing seals, mechanical seals, and dynamic seals. The shaft seal of a reciprocating pump is usually a packing seal. When transporting media where leakage is not permitted, a diaphragm reciprocating pump can be used. Rotary pumps (including vane pumps, rotor pumps, etc.)
ALLWEILER motor Germany ALLWEILER model ALLWEILER price
ALLWEILER motor refers to a motor that, under standard environmental conditions, operates continuously at 100% rated load within the 10%~100% rated speed range, with temperature rise not exceeding the motor's specified allowable value. When the slip of an asynchronous motor does not change significantly, the speed is proportional to the frequency; thus, changing the power supply frequency changes the speed of the asynchronous motor. During variable frequency speed control, it is always desired to keep the main magnetic flux constant. If the main magnetic flux is greater than the flux during normal operation, the magnetic circuit becomes oversaturated, causing an increase in excitation current and a decrease in power factor; if the main magnetic flux is less than normal
