Background

Wind power resources are green renewable energy sources, are inexhaustible and are inexhaustible. At present, many countries are dedicated to developing wind power resources due to the consideration of environmental protection, and the structure and the installation mode of the domestic wind power generation gear lubrication system are basically fixed after years of development, so that a new structure form and a new installation mode are lacked.

All be equipped with the transition valve block between current wind-powered electricity generation gear box lubricating system's the filter oil inlet and the oil pump export, be used for installing two check valves and a relief valve respectively, during manufacturing, this kind of structure must process a transition valve block for install three valve, original purpose is through the different demands of transition valve block adaptation, actually the hydraulic fluid port position that these three valves correspond is basically fixed, need adjust very few, increased part quantity during manufacturing, and then increased manufacturing cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide an integrated filter device which is compact in structure and cost-saving, and realizes miniaturization, simplification and integration of the filter device.

The technical scheme adopted by the utility model is as follows:

the integrated filter device comprises an integrated filter, a transition plate and a motor pump, wherein a first one-way valve and a second one-way valve are arranged in a filter head at the bottom of the integrated filter, the first one-way valve and the second one-way valve are arranged inside the filter head from the side surface of the filter head, a safety valve is arranged at an oil inlet of the filter head, the safety valve is arranged at the oil inlet of the filter head from the side surface of the filter head, and the integrated filter is connected with the motor pump through the transition plate.

In this device, integrated form filter's oil inlet punishment do not is equipped with pressure sensor and pressure measurement and connects.

In the device, a rigid connection is adopted between the integrated filter and the transition plate.

In the device, a transition plate is rigidly connected with a motor pump.

Preferably, the bottom of the filter head is provided with a sewage draining outlet.

The utility model has the following beneficial effects:

the utility model optimizes the installation positions of a plurality of valves through technical integration, cancels the arrangement of a transition valve block, and integrates an extension part, thereby realizing the miniaturization, simplification and integration of the utility model, having simple structure and ingenious design, not only saving cost, but also simplifying the structure, improving reliability, reducing the occupied space of the gear box in a cabin, having fewer parts, fewer leakage points and convenient maintenance, and being suitable for filtering the oil of the wind power generation gear box.

Detailed Description

The utility model will be further described with reference to the accompanying drawings in which:

as shown in fig. 1-4, the present invention includes an integrated filter 1, a transition plate 2 and a motor pump 3, a first check valve 1a and a second check valve 1b are disposed in a filter head 1d at the bottom of the integrated filter 1, the first check valve 1a and the second check valve 1b are mounted inside the filter head 1d from the side of the filter head 1d, a safety valve 1c is disposed at an oil inlet of the filter head 1d, the safety valve 1c is mounted at the oil inlet of the filter head 1d from the side of the filter head 1d, and the integrated filter 1 is connected with the motor pump 3 through the transition plate 2.

In the working process of the gear box, metal abrasive dust is substituted, impurities in air enter, and engine oil oxides are generated. Make the impurity in the lubricating oil increase gradually, the effect of filter is with impurity separation, the filtration in the lubricating oil to reach and improve lubricating oil quality and live time, reduce the interior part friction of gear box, increase gear box life's purpose. Because the lubricating oil has high viscosity and high impurity content, the integrated filter 1 can adopt double-precision filtration.

Preferably, the first check valve 1a, the second check valve 1b and the safety valve 1c are made of steel, and the safety valve 1c is used for protecting the system.

In this device, integrated form filter 1's oil inlet punishment do not is equipped with pressure sensor 4 and pressure measurement joint 5, and pressure sensor can the pressure of real-time supervision oil inlet department, and pressure measurement joint 5 department can take a sample fluid, conveniently detects fluid behaviour in service.

In the device, the integrated filter 1 is directly and rigidly connected with the transition plate 2, the transition plate 2 is directly and rigidly connected with the motor pump 3, and the side surface of the filter head 1d of the integrated filter 1 is not provided with a valve block, thereby simplifying the structure.

The bottom of the filter head 1d is provided with a drain outlet 1e, and the drain outlet 1e is opened to discharge oil.

The using process of the utility model is as follows:

as shown in fig. 1-4, oil enters from the port C and the port D of the filter head 1D, enters the integrated filter 1 through the first check valve 1a and the second check valve 1b, is filtered, the pressure sensor 4 monitors the pressure at the oil inlet in real time, the safety valve 1C protects the system, and when the pressure is higher than the opening pressure of the safety valve 1C, the safety valve 1C is opened, and the oil flows out from the port E.

Other processes of the present invention may employ existing techniques.

While the preferred embodiments of the present invention have been illustrated, further modifications of the utility model will occur to those skilled in the art and are intended to be included within the scope of the present invention.
