(1) Introduction

According to the original machinery commissioned and Technology Development Plan [87400842] request, the original machinery commissioned standardization and Shanghai Mechanical and Electrical Industry Bureau of Intelligence jointly revised GB1161 standards, and drafted the oil standard GB new program, the company undertook the production of oil standard trial and manufacturing task. September 1988 held in Shanghai, "the oil standard national label will certainly", delegates agreed that the product has advanced design, reasonable structure, complete specifications, etc., by the Shanghai Institute of hydraulic and pneumatic testing, the indicators in line with GB GB technical requirements, and the inclusion of GB program submitted to the ministerial review. 1990 the formal implementation of the national GB1161-90 new standards, to fill a gap in domestic oil standard standardization.

I produced YWZ series level liquid thermometer is the fuel tank, the essential accessory lubrication system, cooling box and the gear box, which can indicate the level of liquid and liquid temperature. This product has a novel design, beautiful, liquid level and temperature display clear, rich three-dimensional features, it has excellent assembly performance, rugged, crack, earthquake, leakage and other advantages. The product is based on tank capacity, designed for 25 kinds of different specifications. Three Guarantees products, users are welcome to choose.

(4) Installation Method & Accessories

According to the selection specifications center distance (E) size, processing good two mounting holes, such as the wall thickness of the tank when ≤10mm, only two mounting screws for aperture φ11mm; if the wall thickness of the tank> is 10mm, only two mounting screws threaded hole M10. These two holes on the plane to be processed, in order to prevent oil leakage after installation. Level Meter Accessories: nuts, washers, sealing each two flat washers, provided by the company.

(5) temperature range and under pressure

Temperature Temp.range: -20 ℃ to + 100 ℃ and in Celsius and Fahrenheit

Pressure Pressure class: 0.1 ~ 0.15MPa

(6) Ordering Information

According tank level to choose the specifications, please contact holes center distance of 250mm without a thermometer level timing model YWZ-250; For with the thermometer, the model YWZ-250T.

NOTE: Do not touch the surface of the product with banana water.

Note: 1. YWZ series YD-type level gauge and check valve supporting the use of removable fluid level gauge does not have to let go of the oil tank.

　　　2. YD-type dimensions, see 119.

　　　3. YWZ for water - when glycol, can not bring a thermometer.
