Abstract
The utility model relates to an automatic/manual pressure regulator for high pressure pumps, which comprises a gas pressure relief valve, a pressure adjusting nut, an automatic/manual conversion mechanism, a retarder and a motor, wherein an output shaft of the motor is in transmission connection with one end of the automatic/manual conversion mechanism through the retarder, and the other end of the automatic/manual conversion mechanism is connected with a valve rod of the gas pressure relief valve through the pressure adjusting nut. The remote control of the motor can be carried out by the adoption of a remote control device according to work conditions, and automatic regulation is realized. The utility model has the advantages that the pressure of high-pressure pumps is regulated by the adoption of pressure gas, the pressure regulation is stable, the high-pressure pumps are difficult to abrase, and the service life is long; an automatic and a manual pressure regulation devices are organically combined into a whole, the pressure regulation of the high-pressure pumps can be remotely controlled, and the outlet pressure of the high-pressure pumps can also be regulated on site; the structure is simple, and the automatic and the manual pressure regulation modes are convenient to convert.
Description
Technical field
The utility model relates to a kind of controlling device of high-pressure service pump outlet pressure, is used for outlet pressure long-range or the Field adjustment high-pressure service pump.
Background technique
What existing this high-pressure service pump outlet pressure controlling device adopted is the regulator of pilot valve formula, utilizes the fluid pressure in the pump housing to carry out the pressure adjusting of high-pressure service pump outlet liquid.Its shortcoming is that the pilot hole of pilot valve is too little, and the vertebra point quick abrasion of spool may wear to a certain degree and just can't regulate pressure, needs frequent spool valve seat, the user cost height changed.Existing this high-pressure service pump outlet pressure controlling device also can be carried out automatic automatic Regulation by remote control, but automatic Regulation and manual voltage regulation are two covering devices, replaces and uses trouble.
Summary of the invention
The purpose of this utility model just provides a kind of novel high-pressure service pump pressure regulator, solves the pilot hole spool vertebra point quick abrasion that existing regulator exists, and the spool valve seat is changed frequent, and pressure is regulated unstable; Automatic Regulation and manual voltage regulation are two covering devices, replace the problem of using trouble.
The technical solution of the utility model is: comprise gas pressure reducer, look nut, slide block shaft joint, attaching nut, retarder and motor, with pressed gas by sending into the spool of regulating in the high-pressure service pump pump head in the pump head after the reduction valve decompression, thereby reach the purpose of pressure regulation; Unclamp the attaching nut, will reduce pressure valve rod and retarder are thrown off, and just can carry out manual voltage regulation.
The utility model has the advantages that: adopt pressed gas that high-pressure service pump is carried out pressure and regulate, pressure is regulated steadily, and is not easy to wear, long service life; Will be automatically and hand-operated pressure regulation appliance organically be combined into an integral body, pressure that both can the telecontrol high-pressure service pump is regulated, outlet pressure that also can the Field adjustment high-pressure service pump is simple in structure, automatic, manual voltage regulation mode easy switching.
Description of drawings
Fig. 1 is a general structure schematic representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises air pressure reducing device 1, look nut 2, slide block shaft joint 3, attaching nut 4, retarder 5 and motor 6.Pressed gas enters gas pressure reducer by suction port 7, rotates the air pressure that screw press can be regulated outlet 8 places, and gas enters the high pressure pump head through the decompression back by exporting 8, carries out the high-pressure service pump outlet pressure and regulates.Slide block shaft joint 3 and attaching nut 4 constitute automatically and manual switch mechanism.
Using method of the present utility model is as follows:
During automatic Regulation, the sensor of remote control is passed to controller with pressure information, sending command control motor 6 rotates, by retarder 5 deceleration strip movable slider shaft joints 3, look nut 2 rotations, look nut 2 is (or backward) moving linearly while rotating forward, the gas pressure at outlet 8 places of adjustments of gas reduction valve 1, outlet 8 is connected with the high pressure pump head, thereby reaches the purpose of the outlet pressure of adjusting high-pressure service pump.
During manual voltage regulation, unclamp attaching nut 4, unload bottom slide block shaft joint 3, look nut 2 and retarder 5 are thrown off, just can directly rotate look nut 2 and carry out pressure regulation with hand.
