It is possible to install a pressure accumulator in the hydraulic circuit
1. Replenish the oil leakage of hydraulic lines.
2. Absorb pulse pressure , protect the system and stabilize the pressure.
3. As a temporary auxiliary hydraulic source in case of emergency .

nThe thermometer is used to measure the temperature change in the hydraulic oil tank. The types of thermometers include alcohol thermometer, mercury thermometer, bimetal thermometer, thermocouple thermometer, etc. The thermometers commonly used in hydraulic control systems include alcohol thermometers and mercury thermometers.
nThe thermometer must be installed in a position where it is easy to observe to facilitate the observation of the oil temperature. It is often installed in the oil level gauge.

8-6 filter (FILTER) P488 TOP
The material of the filter is brass wire, stainless steel wire, filter paper, etc. When the mesh of the filter is too large, the filtering effect is poor; but if the mesh is too small, it is easy to cause clogging, so the following factors must be considered when selecting the filter:
n1. Viscosity and flow of hydraulic oil
n2. Pressure drop
n3. Filtering effect and degree
n4. Filter strength, high reliability and temperature influence;
n5. Cost
