Abstract

The utility model relates to a piston type water pump which comprises an upper pump body (1) and a lower pump body (2), wherein a fixing pipe (3) is connected with the side face of the lower pump body (2), the upper pump body (1) is connected with the lower pump body (2) through a pump shaft (6), a motor (4) is arranged at the upper end of the upper pump body (1), blade wheels (5) and propeller wheels (7) are arranged in the upper pump body (1), an inner cavity (8) is arranged in the lower pump body (2), an opening is formed in the lower end of the inner cavity (8), a water outlet (11) is arranged in the opening, a hydraulic cylinder is arranged in the motor (4), and a piston (14) is arranged in the hydraulic cylinder. Due to the fact that the hydraulic control type piston and the hydraulic cylinder are arranged in the motor, the piston type water pump has the advantages that piston type motion of water pump body is achieved, and water pumping effects of the water pump are driven by repeated twitching in an up-and-down mode.

Description

Piston pump

Technical field

The utility model relates to a kind of water pump, relates in particular to a kind of piston pump, belongs to the hydraulic set field.

Background technique

Water pump is a kind of equipment common in the waterpower field, all is widely used in various industries and field, such as be used for the fields such as plumbing, petrochemical industry, metallurgy in the city, not only in the city, in rural area and remote districts very widely purposes is arranged also.The major function of water pump is that water is transferred to other place from short by internal motivation, such as the highland, so the predominant use of water pump is for pump water, in every attribute of water pump, water pumping efficiency is very important index, also is the important references of weighing the water pump assembly power consumption.The implication of water pumping efficiency refers to the ratio of current output power and input power, and the efficient of water pump is higher, shows that the utilization rate of electrical of this water pump is larger.

Traditional water pump manufacture process is very coarse, casting process is fairly simple, material is selected relatively poor, the surface ratio of the flowing water section in the pump housing of therefore producing is more coarse, nature can increase the friction factor on the flow passage surface in fluid and the pump housing like this, increase the mistake flow resistance of water, thereby reduced the efficient of water pump self.In the long-term use of water pump, along with the raising of frequency of utilization, owing to the long-term reasons such as getting rusty of causing, corrosion of using, can form various pits even the situations such as perforation occur at pump body.Especially runner or impeller part are because outer wall is thinner, so more be prone to accidents.

Simultaneously, water pump also has other some problems at present, all is in sealing state such as the water in the water cavity of the general pump housing, when running into cold air or weather, easily freezing and expansion causes pump housing bursting by freezing, has affected working life and the using scope of the pump housing.For another example, common water pump all lacks water-leakage protecting device, just has water when occuring to bore a hole when leaking and leaks in motor cavity, and motor easily burns out, thereby causes the generation of accident.And aforesaid water pump corrosion, the situation such as get rusty can cause the utilization efficiency of water pump seriously to reduce, and have greatly shortened the working life of water pump, when serious even cause scrapping.This situation can cause inevitable loss to enterprise, has also improved the operation cost of enterprise.
