为满足液压元件厂成批生产方向阀,检测出厂产品之用,由我所设计的GYS_1多能方向阀试验台在杭州金属板厂的协助作已试制成功,于一九七五年七月上旬在广州鉴定完毕,并建议由杭州金属板厂生产。 GYS_1多能方向阀试验台的主要测试项目有:1.换向可靠性(包括换向停留);2.压力损失;3.电压降(电磁阀电磁铁的电压降);4.内、外泄漏;5.电磁铁及电磁阀反力的测定。测试的方向阀类型及范围较广,只须更换工作台固定配流板上不同的过渡
To meet the hydraulic components factory batch production direction valve, the detection of manufactured products, I designed by the GYS_1 multi-function directional valve test stand in Hangzhou metal plate factory assistance has been trial success, in early July 1975 Accreditation in Guangzhou is completed, and proposed by the Hangzhou metal plate factory production. The main test items of GYS_1 multi-function directional valve test stand are: 1. The commutation reliability (including the commutation stop); 2. The pressure loss; 3. The voltage drop (solenoid valve voltage drop); 4. Inside and outside Leakage; 5 electromagnet and electromagnetic valve reaction force determination. Test the direction of the valve type and a wide range, only need to change the table fixed on the different flow transition plate
