Manufactur standard Tubular Type Level Gauge - PAF Series Pre Compressed Air Temperature Purifier – Xinyuan

(1)Introduction 

PAF series of precompressed air temperature cleaner is based on UCC, France SECOMA. The prototype of the prepressure air leakage device produced by the company and Germany REXROTH Company is made by the technical mapping after the introduction and further design and improvement according to the technical requirements of the domestic host equipment factory. After supporting the use of the host and technical test, it is proved that the performance and technical indicators have reached the technical requirements of similar products abroad, the connection size is consistent with foreign products, and can be exchanged and replaced, the price of its products is only 1 smart of the import price, which can save a lot of foreign exchange for the country. This product has the advantages of small volume, reasonable structure, beautiful and novel shape design, stable overtemperature performance, small pressure drop, easy installation and use, and is welcomed by the majority of users.

(2) Purpose and working principle

PAF series products are suitable for construction machinery, vehicles, mobile machinery and hydraulic system oil which need to have pressure. This product is composed of four parts: air superheater, inlet check valve, exhaust check valve and refueling superheater, thus simplifying the structure of the oil bit and helping to purify the oil. When hydraulic system working inside the fuel tank of liquid level from time to time, rise or drop down when PAF inhaled air products, after wimbledon.

(3) into the inlet one-way valve automatically diction, slightly into the oil, when the pressure is less than the target in the cabinet pressure, exhaust valve  in the closed state, can maintain the tank due to pressure, improve the oil pump self-priming capacity, maintain the liquid inside the tank body is smooth, Avoid the fluid in the tank due to oscillations or commotion caused by the pump may be empty and other failures. When the working cycle flows back to the tank to make the liquid level rise, the temperature of the working oil also rises, generating oil mist gas and increasing the pressure in the tank; When the pressure in the oil is slightly greater than the predetermined pressure, the exhaust check valve

automatically open to exhaust, until the pressure in the box is equal to the predetermined pressure elbow, the exhaust check valve

automatically closed. In this way, the back and forth circulation can not only protect the normal operation of the hydraulic system, but also extend the working cycle and life of the oil and components.

PAF – series breather filters are used on the tank. The filter is composed of an air filter、an air inlet check valve、 an exhaust check valve and an oil filter. During operation of hydraulic system. The oil level in the tank changes frequently and the air above the oil surface flows in and out in turn, Hence the breather filter will keep air in the tank clean and under right pressure.
