oil filter truck composition and characteristics

Humanized design of oil filter truck, low noise, easy operation, long maintenance interval, low energy consumption and operation cost saving. Do you know the composition and characteristics of the oil filter truck?


Composition of oil filter truck:


The oil filter truck is composed of primary filter, oil pump and filtering device. The primary filter is a cylindrical metal mesh to prevent the large solid particles in the impure oil from entering the oil pump. The oil pump is usually a gear pump, conveying impure oil into the filter unit. The filter device is a small hand pressed plate frame filter press car, using special filter paper as filter medium. Under the pressure of the oil pump, the impure oil enters the plate frame filter press car and becomes filtered oil through the filter paper. The solid impurities in the oil are retained on the surface of the filter paper, and a small amount of water is absorbed by the pores of the filter paper. The filtration pressure is usually less than 0.3 MPa. When there are too many impurities deposited on the surface of the filter paper and the filtration pressure rises to 0.35 MPa, or when the water absorbed by the filter paper is nearly saturated and the residual water in the filter oil is no longer reduced, the filter paper should be stopped and replaced. When the oil viscosity is high, it can be preheated to reduce the viscosity before filtration.


This kind of oil filter can only remove solid impurities and a small amount of water, and is suitable for the purification of general electrical oil and lubricating oil. When the oil contains too much moisture and impurities, it must be pretreated before being sent to the oil filter. The treatment capacity of ordinary oil filter truck is 25-200 L / min. The square filter frame of the filter device has 200 mm, 250 mm, 320 mm, 450 mm, 630 mm, etc. The filter plate and frame are made of cast iron or polypropylene.

Features of oil filter truck:


1. Double stage vacuum pumping speed and advanced dehydration and degassing system, using large area three-dimensional flash technology, can quickly and quickly remove water, impurities, hydrocarbons and other harmful components in the oil, and improve the flash point and withstand voltage strength of insulating oil.


2. It can meet the requirements of vacuum pumping and vacuum oil injection on the transformer body at the installation or maintenance site.


3. Precise filtering system, filter element and multi-stage filtration are densified step by step, which can effectively remove mechanical impurities in oil.


4. Advanced automatic constant temperature control system, automatic liquid level control system, automatic defoaming control system, automatic pressure protection system and excellent configuration ensure high performance operation of the equipment.


5. Online oil filtering, unmanned operation, and operation status displayed by indicator light.


6. The whole machine is equipped with interlock safety protection. The oil drainage system, vacuum system and heating system are interlocked to avoid adverse effects caused by misoperation.
