RU2545475C1 - Method to determine environmental safety of performance of oil service in maintenance of machines - Google Patents

Abstract

FIELD: technological processes.

SUBSTANCE: method to determine environmental safety of machine maintenance includes fixation of a used material onto a screen and its evaluation. Fixation of the material getting during performance of oil service is done on the screen placed under the serviced machine, during every oil service operation. The screen is weighed before and after performance of each operation, after which they evaluate availability of the material on the screen.

EFFECT: method makes it possible to determine environmental safety of performance of each oil service operation during machine maintenance by mass of material on the screen.

Description

The invention relates to the maintenance of motor vehicles, in particular to methods for determining the environmental safety of technical maintenance of cars, tractors, combines and other self-propelled machines.

A known method for determining the environmental safety of diesel engines by the smoke of the exhaust gases / 1 /.

The main disadvantage of this method is that it is suitable for assessing the environmental safety of diesel engines.

The closest technical solution, selected as a prototype, is a method for determining the smoke of exhaust gases of diesel engines based on the deposition of unburned particles on paper, followed by comparing the resulting fingerprint of the exhaust gas with a reference fingerprint / 2 /.

The disadvantage of this method is that it cannot be used to determine the environmental safety of maintenance of motor vehicles. In addition, fingerprint comparisons are made visually, which reduces the reliability of the evaluation results.

The objective of the invention is to provide a method for determining the environmental safety of the performance of lubricating and refueling operations during maintenance of machines.

The essence of the invention lies in the fact that the material used during each lubricating and refueling operation of the machine is fixed on a screen located under this machine. In this case, the screen is weighed before and after each operation. Then, based on the difference in weighing results, an assessment is made of the availability of material on the screen. According to the mass of material on the screen, the environmental safety of each lubricating and filling operation during the maintenance of the machine is determined.

The figure shows a method for determining the environmental safety of technical maintenance of motor vehicles (top view of the serviced tractor, under which the screen is placed). This method can be carried out, for example, in garage conditions as follows.

They clean the platform for maintenance of machines and dry it. On the basis of platform 1, a machine is installed, for example, a tractor 3, under which then a screen 2 is installed with the possibility of fixing materials falling onto it during maintenance of the machine. Previously, this screen is weighed. The first operation is carried out from the list of lubricating and refueling operations, for example, draining oil from the crankcase. After this operation, screen 2 is removed and weighed. Then assess the availability of material (oil) on the screen according to the formula:

, $${\text{Q}}_{\text{Mi}}={\text{Q}}_{\text{Ei}}^{\text{P}}-{\text{Q}}_{\text{Ei}}^{\text{D}}$$

,

, $${\text{Q}}_{\text{Эi}}^{\text{Д}}$$

- масса экрана до и после проведения i-й операции. По массе материала на экране Q_Mi определяют экологическую безопасность выполнения операции, приведенной для примера. Для этого полученную массу материала Q_Mi сопоставляют с допускаемым значением. Аналогичным образом определяют экологическую безопасность других смазочно-заправочных операций.where Q _Mi is the mass of material on the screen when performing the i-th operation, $${\text{Q}}_{\text{Ei}}^{\text{P}}$$

, $${\text{Q}}_{\text{Ei}}^{\text{D}}$$

- the mass of the screen before and after the i-th operation. According to the mass of material on the screen, Q _Mi determines the environmental safety of the operation shown for example. For this, the resulting mass of material Q _{Mi is} compared with the permissible value. Similarly determine the environmental safety of other lubricating and filling operations.

The proposed method allows you to determine the environmental safety of each lubricating and refueling operation performed during maintenance of the machine.
