Recently, a new type of jet sand absorbing device developed by Zhejiang Fangyuan Shipbuilding Co., Ltd. was granted a patent by the State Intellectual Property Office and was awarded a utility model patent certificate.
It is understood that the sand suction port, pump body and sand outlet of the traditional sand-absorbing ship, which is mainly pumped in China, are all arranged on one axis. The sand water mixture sucked from the sand suction port passes directly through the pump body, so that the pump The main components of the pump blades produce huge wear and tear, which causes the ship to change the water pump frequently. Moreover, the installation and maintenance work is large, the investment cost is high, and the economic benefit is low. The new device is simple in equipment, low in cost, and similar to the ship type of the ship, and does not need to be equipped with large special deck machinery and equipment; the operation process is simple, only one person can operate when the sand absorbing operation; because the mud and sand mixture does not pass the water pump Therefore, the pump blade is not easy to be worn, the service life is long, the equipment maintenance is simple, and the replacement cost of the wearing parts is low; the working depth is adjusted by the lifting part of the crotch, and the suction depth can reach 65 meters, relying on the self-weight of the suction pipe and its unique The structure can effectively solve the sand taking problem under the condition of thick mud covering; the production efficiency is high and the sand absorbing cost is low.
