摘要： A system of pumps wherein a first hydraulic motor operatively connected to a first master pump can hydraulically drive a second hydraulic motor operatively connected to a second slave pump. A hydraulic fluid outlet of the first hydraulic motor is fluidically connected to a hydraulic fluid inlet of the second hydraulic motor whereby the first hydraulic motor, operatively connected to the first pump, drives the second hydraulic motor, operatively connected to the second pump, in a hydraulically synchronized manner.

摘要： The proposed method includes an initial checking step, during which a pump of a filtering circuit is operated at a given checking operation frequency meanwhile a pump checking operation value is measured, and using the measured data a calculation of the water flow rate when pump operates at a given operation frequency lower than the given checking operation frequency is performed. The pump is then operated at said given operation frequency for a first filtering period of time. When said period is concluded the checking step, at checking frequency, is newly performed obtaining a new checking operation value, and this value is used to calculate a required operation frequency necessary to produce a flow rate equal to the initially calculated flow rate, and the pump is operated at said new calculated operation frequency for a second filtering period of time.

摘要： A piston is the driven component within a pump. The piston is driven along a longitudinal axis to pump a fluid through the pump. The fluid flows through the piston between an upstream end of the pump and a downstream end of the pump. The piston outputs the fluid into the downstream end of the pump at a vector offset from the longitudinal axis, thereby inducing rotation of the piston throughout the pumping process. Rotating the piston encourages even wear on various components within the pump, such as sealing rings surrounding the piston, thereby increasing the lifespan of the components and increasing the efficiency of the pump.

摘要： An exhaust air conduit for a pneumatically powered pump, in particular, from a coating agent pump in a painting plant, is provided. The conduit includes an inlet for receiving the exhaust air from the pump, an outlet for discharging the exhaust air, and an exhaust air channel in which the exhaust air flows from the inlet to the outlet of the exhaust air conduit, and a housing member in which the exhaust air channel extends. A first thermal insulation element is provided in the region of a direction change of the exhaust air channel, in order to prevent an accumulation of the exhaust air directly at the inner wall of the exhaust air channel and thereby to lessen the cooling of the housing member.

摘要： An axial piston pump has a fluid inlet, a fluid outlet, and a rotatable, one-piece piston housing carrying one or more pistons movable within one or more respective sleeves formed by the housing. A circumferential row of fixed field members is mounted to the housing at a mounting location formed by the housing, the mounting location being radially outward of the sleeve(s). The pump further has a stator surrounding the piston housing and including a circumferential row of armature windings such that the piston housing and the stator form an electro-magnetic motor operable to rotate the piston housing, and a swashplate engaged with the piston(s) such that rotation of the piston housing relative to the swashplate around an axis of rotation produces reciprocating movement of the piston(s) for the pressurisation of fluid received into the sleeve(s) from the fluid inlet and then discharged from the sleeve(s) to the fluid outlet.

摘要： There is provided an airless paint spray pump wherein the pump is a double acting piston pump having an inlet communicating with a source of paint, a motor for driving the pump, a pressure controller for controlling the pressure of the pressurized paint delivered by the pump, and a filter for filtering the paint delivered by the pump. The pump includes features which increase the accessibility of the components thereof, prevent the incorrect installation of the seal packings in the pump cylinder, and allow the assembly of the piston in the pump cylinder properly aligned with the cylinder so as not to damage the seal packings therein.

摘要： A manually actuated feed pump is provided with a primer bulb to be manually actuated by an operator. The primer bulb has a pump chamber. A travel-controlled valve connects the pump chamber to a fuel line. The travel-controlled valve has a valve member that is moved by an actuation travel of the primer bulb into an open position that opens the travel-controlled valve. A first spring is operatively connected to the valve member and to the primer bulb. The primer bulb acts through the first spring on the valve member.

摘要： The present disclosure provides a pump including a cylinder, a plunger, a spring seat, a spring, and a stopper. The cylinder defines therein a cylinder hole. The plunger includes a shaft portion, a seat receiver, and a step surface. The spring biases the plunger in a second direction opposite to a first direction through the spring seat. The stopper includes an engaging portion. The engaging portion restricts, by engaging with the step surface, a movable range of the plunger in the second direction. The stopper defines therein an eccentric hole that has an inner diameter greater than an outer diameter of the step surface. The eccentric hole is eccentric with the plunger and opens through a portion of the stopper other than the engaging portion.
