Description

A hydraulic submersible pump

本实用新型涉及一种潜水泵，特别是涉及一种通过液压马达驱动抽水的液压潜水泵。The utility model relates to a submersible pump, in particular to a hydraulic submersible pump driven by a hydraulic motor to draw water.

目前，市场上的潜水泵都是由电动机作动力、带动水泵叶轮旋转，而水由旋转的叶轮通过出水管把水引出，由于电动潜水泵所用电动机是潜入水中的，因此电机的工作环境不好，容易因漏电、漏水或缺相造成电动机常常烧坏，给用户造成很大的经济损失。At present, the submersible pumps on the market are driven by electric motors, which drive the impeller of the pump to rotate, and the water is led out by the rotating impeller through the outlet pipe. Since the electric motor used in the electric submersible pump is submerged into the water, the working environment of the motor is not good. , It is easy to cause the motor to often burn out due to electric leakage, water leakage or lack of phase, causing great economic losses to users.

本实用新型的目的在于克服现有技术中存在的不足而提供一种在原有电动潜水泵的基础上靠液压马达取代电动机作动力的液压潜水泵。The purpose of the utility model is to overcome the deficiencies in the prior art and provide a hydraulic submersible pump powered by a hydraulic motor instead of an electric motor on the basis of the original electric submersible pump.

本实用新型的目的是这样实现的：由动力装置、靠动力装置提供油压的油泵、通过供油管、回油管和油箱与油泵相连的液压马达以及叶轮壳、叶轮壳上的出水口、安装在叶轮壳中的叶轮和安装叶轮的叶轮轴组成，叶轮轴与液压马达输出轴相连。The purpose of this utility model is achieved in this way: the hydraulic motor connected to the oil pump by the power unit, the oil pump relying on the power unit to provide oil pressure, the oil supply pipe, the oil return pipe and the oil tank, the impeller shell, the water outlet on the impeller shell, the installation The impeller in the impeller shell is composed of the impeller shaft on which the impeller is installed, and the impeller shaft is connected with the output shaft of the hydraulic motor.

本实用新型在原有电动潜水泵的基础上，采用液压马达取代原有的电动机，即安全又减少了无电地区用发电机的麻烦，不仅能完全代替电动潜水泵，而且又比电动潜水泵耐用轻便，因此本实用新型具有结构新颖、轻便耐用、安全可靠、质优价廉的优点。On the basis of the original electric submersible pump, the utility model adopts a hydraulic motor to replace the original motor, which is safe and reduces the trouble of using a generator in an area without electricity. It can not only completely replace the electric submersible pump, but also be more durable than the electric submersible pump. Portable, so the utility model has the advantages of novel structure, light and durable, safe and reliable, high quality and low price.

下面结合附图对本实用新型作进一步说明。Below in conjunction with accompanying drawing, the utility model is further described.

The water outlet 8 on the top, the impeller 6 installed in the impeller shell and the impeller shaft 7 on which the impeller is installed, the impeller shaft 7 is connected with the output shaft of the hydraulic motor 4. One impeller can also be fixed on the impeller shaft 7 and a plurality of impellers can be fixed.

图中动力装置可以是一种柴油机、汽油机、电动机等动力装置。靠动力装置带动油泵工作，通过供油管3向液压马达4输出高压油，从而驱动液压马这4工作，供油管3、回油管9、油箱10、油泵2以及液压马达4形成供油回路，组成一油泵站。高压油驱动液压马达4工作，液压马达4输出轴转动，带动与液压马达4输出轴相连的叶轮轴7转动，从而使叶轮旋转，并产生离心力把水甩出，通过叶轮壳上的出水口把水引向地面。The power device in the figure can be a power device such as a diesel engine, a gasoline engine, or an electric motor. The power unit drives the oil pump to work, and outputs high-pressure oil to the hydraulic motor 4 through the oil supply pipe 3, thereby driving the hydraulic motor 4 to work. The oil supply pipe 3, the oil return pipe 9, the oil tank 10, the oil pump 2 and the hydraulic motor 4 form an oil supply circuit , forming an oil pumping station. The high-pressure oil drives the hydraulic motor 4 to work, and the output shaft of the hydraulic motor 4 rotates, driving the impeller shaft 7 connected to the output shaft of the hydraulic motor 4 to rotate, so that the impeller rotates, and centrifugal force is generated to throw the water out. Water is directed towards the ground.
