[0005] In the pulse type single-piston water pump device with this structure, the oil end piston and the water end piston are positioned by the shaft shoulder of the piston rod, that is, the shaft end of the oil end piston or the water end piston passes through the cylinder bottom or the water end against the cylinder block. The cylinder bottom of the cylinder body is used to realize the positioning of the oil end piston or the water end piston, that is, the cylinder bottom limit. The oil end piston or the water end piston has a large impact force during the movement process. When the bottom of the oil tank or the bottom of the water tank is used, the force on the bottom of the oil tank or the bottom of the water tank is relatively large, which makes the bottom of the oil tank or the bottom of the water tank easy to crack, which requires the bottom of the tank The structure of the cylinder is reliable enough, resulting in the structure of the cylinder bottom being bulky, bulky and heavy

The invention relates to the technical field of water pumps and discloses a telescopic water pump device. The telescopic water pump device comprises a connection flange, an oil tank body, a water tank body and a piston rod, wherein the oil tank body and the water tank body are arranged on two sides of the connection flange respectively; two ends of the piston rod are respectively sleeved in the oil tank body and the water tank body; and the oil tank body and the water tank body are arranged at two ends of the piston rod respectively. The distance from the pressing point between an oil tank piston or a water tank piston and the connection flange to the other end of the piston rod is not greater than the distance from the pressing point between the oil tank piston or the water tank piston and the connection flange to the bottom of the water tank body or the bottom of the oil tank body. The impact force to the tank bottoms of the telescopic water pump device is relatively low; the tank bottom structures are simple; and the telescopic water pump device has a relatively small volume. The invention also relates to a water pump system with the telescopic water pump device.
Description
technical field [0001] The invention relates to the technical field of water pumps, in particular to a telescopic water pump device driven by a hydraulic oil source. The present invention also relates to a water pump system having the above telescopic water pump device. Background technique [0002] When cleaning large equipment such as concrete pump trucks, because these large equipment are large in size and high in height, it is difficult for the human body to reach them, so equipment with strong impact such as water pump devices is usually used to clean them. [0003] The Chinese patent application number 200420115194.1 discloses a pulse type single-piston water pump device, please refer to the specification and accompanying drawings of this patent. [0004] The water pump device includes a water cylinder and an oil cylinder. The sealing ring of the oil cylinder is put into the sealing groove of the oil end piston and the sealing groove of the left end of the piston rod,...
