Abstract
The invention discloses a high-pressure plunger pump capable of increasing flow. A supplying channel is arranged inside a pump body (1). The other end of the supplying channel is communicated with a vacuum cavity (8.2) of a nozzle (8). A bypass channel of an inner cavity of the pump body (1) is formed by a first water channel (1.2) which is arranged vertically and is communicated with a valve opening (1.1) used for installing a main valve and a second water channel (1.4) which is arranged in parallel to a transverse water discharging channel (1.3). One end of the second water channel (1.4) is communicated with the first water channel (1.2). The other end of the second water channel (1.4) is communicated with one end, close to a water outlet (1.3.1), of a water discharging hole (8.3) of the nozzle (8) through a connecting through hole (1.5). A bypass valve is arranged between the first water channel (1.2) and the second water channel (1.4). According to the high-pressure plunger pump capable of increasing the flow, the structure is compact, the flow is large during the low pressure, the pressure loss during the high pressure is effectively prevented, and the cleaning effect is better.
Description
Technical field
The present invention relates to washing machine plunger pump field, particularly one can flow increasing high-pressure plunger pump.
Background technique
Jetting machine makes high-pressure plunger pump generation high pressure water rinse the machine of body surface by power plant (motor, petrol engine, diesel engine).Dirt can be peeled off by it, washes away, and reaches the object on cleaning of objects surface.Because be use water jets under high pressure cleaning dirt, so high-pressure wash is also one of the cleaning mode of universally acknowledged most scientific, economy, environmental protection.The structure of swash plate plunger pump of the prior art is generally: include the pump housing, pump cover, the swash plate be arranged in the pump housing, multiple plungers of being driven by swash plate, pump cover is provided with low pressure intake pipe and high-pressure outlet.The jetting machine of prior art then correspondingly will strengthen working pressure as wanted enlargement discharge, and that is want power of motor enough large, not only cost increases, and motor volume one increases, and the size also corresponding increase of washing machine entirety, uses inconvenience.For this reason, what market has successively occurred some improve can the washing machine of flow increasing, object is the increase realizing the cleaning of low-pressure large discharge when not increasing power and realize range, but problem is, existing high-pressure plunger pump self increases the effect of flow and bad, can not have good raising to cleaning effect.
Summary of the invention
Technical problem to be solved by this invention is: when providing a kind of compact structure, low pressure, flow large and pressure loss when effectively prevent high pressure, cleaning effect better can the high-pressure plunger pump of flow increasing.
The present invention's adopted technological scheme that solves the problem is: one can flow increasing high-pressure plunger pump, comprise the pump housing, be located at the main valve between the waterexit end of high pressure check valve and exhalant canal, swash plate and swash plate promote reciprocating multiple plunger, the side lateral arrangement of the described pump housing has exhalant canal, the end of described exhalant canal is provided with water outlet, nozzle is horizontally arranged with in the middle part of the inner chamber of described exhalant canal, described nozzle is provided with into water aperture away from the side of water outlet, the opposite side of described nozzle is provided with osculum, the middle part of described nozzle is through is provided with vacuum chamber,
The supplementary passage that one end is directly communicated with low pressure intake pipe is provided with in the described pump housing, described supplementary passage is placed in the below of described exhalant canal, the other end of described supplementary passage is connected with the vacuum chamber of described nozzle, and be provided with in described supplementary passage for open during low pressure and high pressure time the supplementary passage one-way valve of closing;
Described pump housing inner chamber is also provided with bypass passageways, described bypass passageways is by vertically arranging and the first water channel be connected with the valve opening for installing main valve and forming with the second water channel that the exhalant canal of transverse direction be arranged in parallel, one end of the second described water channel is connected with the first water channel, and the other end of the second described water channel is connected near one end of water outlet with the osculum of nozzle by connecting through hole; Be provided with between the first described water channel and the second water channel for close during low pressure and high pressure time open the bypass valve of the second water channel.
Compared with prior art, the invention has the advantages that: this can be provided with the supplementary passage that one end is directly communicated with low pressure intake pipe in pump housing of flow increasing high-pressure plunger pump, supplementary passage is placed in the below of exhalant canal, and the other end supplementing passage is connected with the vacuum chamber of nozzle through supplementing passage one-way valve; When needs low pressure and mass flow cleans, after being adjusted to low pressure, because nozzle to be less than the diameter of vacuum chamber away from the side of the water outlet internal diameter be provided with into water aperture, negative pressure can be formed at vacuum chamber, then low-pressure water with regard to low pressure intake pipe directly through supplementing passage suck vacuum chamber and along with nozzle water inlet aperture in the water that enters spray from water outlet through hydraulic giant together, significantly realize the increase of working flow when there is no larger production power.And produce pressure loss through nozzle in order to avoid high pressure water when being transferred to high-pressure wash, pump housing inner chamber of the present invention is also provided with bypass passageways, bypass passageways is made up of the second water channel of the first water channel be connected with the valve opening for installing main valve vertically arranged and cross setting, the other end of the second described water channel is connected near one end of water outlet with the osculum of nozzle by connecting through hole, and is provided with the bypass valve being used to open or close the second water channel between the first water channel and the second water channel.That is utilize bypass valve to walk around nozzle directly arrive water outlet to control this road high pressure water of bypass passageways, effectively prevent pressure loss, serve good distributional effects.Project organization of the present invention closely, stable and reliable for performance, directly on the pump housing, carry out structural improvement, cost is lower, and no matter is that low pressure and mass flow or high pressure range aspect all have very excellent performance, has good raising to cleaning effect.
