Description
一、技术领域1. Technical field
本实用新型涉及发动机机油压力低的故障检测工具。The utility model relates to a fault detection tool for low engine oil pressure.
二、背景技术2. Background technology
发动机必须保证一定的润滑油压力，才能保证正常工作。因此，发动机润滑系统承担着对运动零部件的压力润滑作用。如果由于润滑油道泄漏，就会导致机油压力下降，发动机将无法正常运转，甚至会导致产生运动零件咬死或损坏的严重后果。为此，在发动机没有检视窗口的全封闭情况下，对机油压力低的柴油机故障现象，检修人员很难在最短时间内检测出故障发生原因及部位，通常的方法是只能凭经验进行猜测、查摸，然后进行重复试车，这样既浪费时间，又浪费能源。The engine must ensure a certain lubricating oil pressure in order to ensure normal operation. Therefore, the engine lubrication system is responsible for the pressure lubrication of moving parts. If the lubricating oil passage leaks, the oil pressure will drop, the engine will not be able to run normally, and it will even cause serious consequences of seizing or damage to the moving parts. For this reason, when the engine is fully closed without inspection windows, it is difficult for maintenance personnel to detect the cause and location of the fault in the shortest time for diesel engine faults with low oil pressure. The usual method is to guess based on experience. Investigate and then carry out repeated test runs, which is a waste of time and energy.
三、发明内容3. Contents of the invention
本实用新型提供一种发动机机油压力低的静态故障检测工具，将压缩空气注入全封闭的润滑油道内，检修人员就能在发动机静止状态下，迅速检测出机体主油道打穿或机油滤清器调压阀泄漏等故障。The utility model provides a static fault detection tool with low engine oil pressure. Compressed air is injected into a fully enclosed lubricating oil passage, and the maintenance personnel can quickly detect the breakdown of the main oil passage of the engine body or the oil filtration in the static state of the engine. Pressure regulator valve leakage and other failures.
本实用新型是这样实现的：一种发动机机油压力低的静态故障检测工具，压力调压阀的一侧固定安装有一进气接头，另一侧与测量座固定联接，压力表安装于压力调压阀上方，测量座的出气口平面与发动机机油吸油口平面固定联接，测量座上的出气口与润滑油道贯通，进气接头与压力调压阀、压力表、测量座和出气口贯通。The utility model is realized as follows: a static fault detection tool for low engine oil pressure, one side of the pressure regulating valve is fixedly installed with an air inlet joint, the other side is fixedly connected with the measuring seat, and the pressure gauge is installed on the pressure regulating valve. Above the valve, the air outlet plane of the measuring seat is fixedly connected with the plane of the engine oil suction port, the air outlet on the measuring seat is connected with the lubricating oil passage, and the air inlet joint is connected with the pressure regulating valve, pressure gauge, measuring seat and air outlet.
当压缩空气通过进气接头、压力调压阀、测量座和出气口进入全封闭的发动机润滑油道后，就能通过泄漏气声或位于发动机润滑油道终端的压力表读数，迅速找到机体主油道打穿或机油滤清器调压阀泄漏等故障发生原因及部位。由于发动机们在静止状态下进行，所以操作简便，省时省力。When the compressed air enters the fully enclosed engine lubricating oil passage through the intake joint, pressure regulating valve, measuring seat and air outlet, the main body of the body can be quickly found through the sound of leaking air or the reading of the pressure gauge at the end of the engine lubricating oil passage. Causes and locations of failures such as oil passage puncture or oil filter pressure regulating valve leakage. Since the engines are in a stationary state, the operation is simple, time-saving and labor-saving.
