摘要： A pump torque control system is capable of preventing hunting due to interference between speed sensing control and control of an engine speed of a prime mover when the temperature of a hydraulic fluid is low.A maximum absorption torque is set in a regulator 31 that controls displacement volumes of hydraulic pumps 2 and 3 based on a deviation between target and actual engine speeds of a prime mover 1. A second modification factor calculating section 45 and a control gain modifying section 49, which are included in a controller 23 that performs speed sensing control to ensure that the maximum absorption torque of the hydraulic pumps 2 and 3 is reduced, change a control gain of the speed sensing control based on a value detected by the hydraulic temperature sensor 34 to ensure that the control gain is reduced as the temperature of the hydraulic fluid is reduced.

摘要： A pressure washer system includes an internal combustion engine and a water pump. The internal combustion engine includes an engine block forming a chamber and a cover for the chamber. The cover has an area designed to hold a lubricant. Additionally, the engine includes a crankshaft within the chamber. The water pump includes a pumping mechanism, an inlet, an outlet, and a fluid passage. The pumping mechanism is powered by the crankshaft. Water enters the pump through the inlet and exits the pump through the outlet. The fluid passage extends between the inlet and the outlet. A portion of the fluid passage is formed in the cover of the engine. Heat transfers from the lubricant of the engine to the water of the water pump during operation of the pressure washer system.

摘要： A method of de-watering during intermittent dry running periods with a self-priming centrifugal pump is presented. Centrifugal pumps, as opposed to diaphragm pumps, are advantageous because they are less expensive and can provide greater capacity. The shaft seals are sensitive, however, to frictional heating when water flow is interrupted. In some situations, this fractional heating may desiccate self-priming. The inventive concept provides a continuous stream of pressurized water moving through the pump to cool the seal and sustain priming capability without substantially impairing the ability of the pump to resume wet operation.

摘要： A wheeled, manually movable, internal combustion engine powered pressure washer is mounted in a rigid frame formed of tubular steel elements. A pair of aligned wheels is pivotally mounted independently to each opposite side of the frame. Each pair of aligned wheels is provided with a pivot pin mechanism that enables the rear wheels to be lifted of the ground to facilitate pivoting the unit on the front wheels. The internal combustion engine is mounted toward the front end of the frame, and the pump toward the rear end of the frame. The upper front portion of the frame houses a fuel tank completely within the outline of the frame, and the tank holds more than two gallons of fuel.

摘要： Disclosed are a hydraulic pump control apparatus and a hydraulic pump control method of a construction machine. The hydraulic pump control apparatus includes a pump control unit for controlling a discharge pressure of a hydraulic pump driven by an engine. The pump control unit includes: a pressure setting value calculating unit configured to calculate a pressure setting value based on an engine output torque estimating value or an engine RPM; and a breakdown treating unit configured to select one of the pressure setting value and a pressure command value according to a breakdown of the swash plate angle sensor to output the selected value. Since the pump is controlled according to a pressure setting value obtained by calculating the pressure setting value based on the engine output torque estimating value, the absorption torque value of the pump does not exceed the maximum torque value of the engine even when the swash plate angle sensor breaks down. Accordingly, a phenomenon of stopping the engine can be prevented even if the swash plate angle sensor breaks down during a high-load operation of the engine.
摘要翻译：公开了一种施工机械的液压泵控制装置和液压泵控制方法。液压泵控制装置包括用于控制由发动机驱动的液压泵的排出压力的泵控制单元。泵控制单元包括：压力设定值计算单元，被配置为基于发动机输出转矩估计值或发动机RPM计算压力设定值; 以及击发处理单元，其被配置为根据所述斜盘角度传感器的击穿来选择所述压力设定值和压力指令值中的一个，以输出所选择的值。由于根据通过基于发动机输出转矩估计值计算压力设定值而获得的压力设定值来控制泵，所以即使在斜盘角度时，泵的吸收转矩值也不会超过发动机的最大扭矩值传感器故障。因此，即使在发动机的高负荷运转时旋转斜盘角传感器发生故障，也能够防止发动机停止的现象。
