Abstract
The utility model discloses an adjusting device and particularly relates to an oil pressure constant device of a hydraulic oil pump. The purpose is to overcome the defects in the prior art and provide the oil pressure constant device of the hydraulic oil pump. The oil pressure constant device is simple in structure, convenient to use and capable of enabling oil pressure in a valve body to be constant. The oil pressure constant device comprises an oil tank, the valve body, the pump and an oil-conveying pipe. The valve body is connected with the oil tank through a pipeline, the pump is arranged on the pipeline, and the oil-conveying pipe is connected with the valve body. A controller and a pressure gauge are further arranged on the oil tank. A regulating valve is connected to the valve body through a pipeline, the other end of the regulating valve is connected with the oil tank, a pressure detector is arranged in the pipeline, connected with the regulating valve, of the valve body, the pressure detector is connected with the pressure gauge, the pressure gauge is connected with the controller, and the controller is connected with regulating valve. The structure is reasonable in design, the situation that due to overlarge pressure in the valve body, excessive hydraulic oil is input into a steel wire rope constant tension machine is effectively reduced, and the phenomena that twitching and unevenness happen because tension of a steel wire rope is overlarge are avoided.
Description
Technical field
The utility model relates to a kind of controlling device, especially a kind of oil pressure constant device of hydraulic-pressure pump.
Background technique
Conveyor belt, be a kind of device that is widely used in the conveying in the industries such as cement, coking, metallurgy, chemical industry, iron and steel, mainly band core body and rubber cover, consists of.
Conveyor belt adopts different band core bodys according to the difference of its transportation material, wherein is with core body mainly to comprise nylon material, wire rope and EP polyester., when adopting wire rope as the conveyor belt with core body during fabrication, need first the tension force of wire rope to be regulated.
At present, the adjusting of steel wire rope tension is mainly to adopt the permanent tension machine of wire rope to regulate, and topmost or by hydraulic oil pump device, regulate.Existing hydraulic oil pump device mainly is comprised of oil cylinder, valve body, pump and transport pipe, by pump, hydraulic oil is extracted in valve body and enters in the permanent tension machine of wire rope through transport pipe, in this course, there will be the pressure in valve body excessive, cause the hydraulic oil of exporting more, thereby increased the pressure in the permanent tension machine of wire rope, make that steel wire rope tension is excessive twitches, cause wire rope irregular phenomenon to occur, directly affect the quality of conveyor belt finally.
The model utility content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, and provides a kind of simple in structure, and is easy to use, the oil pressure constant device of the hydraulic-pressure pump of the constant valve body internal pressure of energy.
In order to achieve the above object, the oil pressure constant device of a kind of hydraulic-pressure pump that the utility model is designed, it comprises fuel tank, valve body, pump and transport pipe, and valve body is connected by pipeline with fuel tank, and pipeline is provided with pump, and transport pipe is connected with valve body; Also be provided with controller and pressure gauge on described fuel tank; Be connected with modulating valve by pipeline on described valve body, the other end of modulating valve is connected with fuel tank, is provided with pressure detector on valve body with in pipeline that modulating valve is connected, and pressure detector is connected with pressure gauge, pressure gauge is connected with controller, and controller is connected with modulating valve.
The oil pressure constant device of the resulting hydraulic-pressure pump of the utility model, the numerical response that pressure detector will detect is to pressure gauge, when the valve body internal pressure excessive, controller regulating and controlling valve is opened, the numerical value that will detect when pressure detector is in normal range (NR) the time, and modulating valve is in closed condition.This reasonable in design, effectively reduced and caused because valve body pressure is excessive having avoided steel wire rope tension excessive with in the too much permanent tension machine of hydraulic oil input wire rope, and the generation of twitch and out-of-flatness phenomenon occurs.
