Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, being realized purpose and effect, below in conjunction with mode of execution and cooperate accompanying drawing to give in detail explanation.
See also Fig. 1, present embodiment provides a kind of high-pressure water pump, comprises water pump body 1 and regulator, and described regulator comprises regulating circuit 6, outlet pressure sensor 4, pressure adjustment relief valve 3 and speed probe 2; Described regulating circuit 6 comprises pressure transmitter device 5; Described water pump body 1 is connected with the output shaft of external pneumatic motor, and described speed probe 2 is located on the joint of described water pump body 1 and external pneumatic motor; Described pressure adjustment relief valve 3, outlet pressure sensor 4, pressure transmitter device 5 are installed in the outlet end of described water pump body successively, and described outlet pressure sensor 4, pressure adjustment relief valve 3 and speed probe 2 all are electrically connected with described regulating circuit 6.
The hydraulic pressure that the technical program is regulated in water pump body 1 pump by pressure adjustment relief valve 3, then respond to the hydraulic pressure of water pump bodies 1 outlet end by outlet pressure sensor 4, then regulating circuit 6 receives the sensor signal that outlet pressure sensor 4 transmits, send device 5 to regulate the hydraulic pressure of water pump bodies 1 outlet end and the rotating speed of regulating and controlling pneumatic motor according to the sensor signal pilot pressure change that receives, and the rotating speed of the Signal Regulation pneumatic motor that transmits according to speed probe 2, thereby can automatically control, regulate the discharge pressure of high-pressure water pump.Pass through the utility model, regulating circuit is according to the hydraulic pressure in the pressure-regulating overflow valve regulation water pump body pump, according to the hydraulic pressure of outlet pressure sensor induction water pump body outlet end, regulate the hydraulic pressure of pump outlet and the rotating speed of regulating pneumatic motor according to speed probe according to pressure transmitter device, thereby is able to automatic control, regulate the discharge pressure of high-pressure water pump.
The utility model improves to be had, and the structure of the outlet of described water pump body 1 can connect with fire-extinguisher water hose or the fire-fighting lance of standard.So just can directly water pump be connected with fire-fighting lance or with fire-extinguisher water hose, save cost, simple in structure.
In another concrete mode of execution, the rifle head front end of described fire-fighting lance is provided with the current part flow arrangement.This part flow arrangement can for simple shunting tooth, also can be the device of current being shunted or current in the fire-fighting lance are become spray effect that has that can buy on the market.So just current in the fire-fighting lance are formed shunting even water smoke, just can put out the flare of closer distance, also be not easy to stay the dead angle, and water smoke has formed one deck water quality protection layer, the probability that the reduction operator are burnt around being wrapped in operator.
The utility model also provides a kind of fire-protection equipment that comprises above-mentioned high-pressure water pump, can improve fire-fighting efficiency.The function of above-mentioned high-pressure water pump and structure are described at preamble, do not repeat them here.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
