  ZTYE-ZL30 Main Adjustment Pressure Valve:
Features of the Products:
1. Because the valve has the functions of amortize, energy accumulation, pressure adjustment, in the process of shift gears, avoid stroke, ensure the safety and comfortable to driver and rider.
2. At instant of gear shifting , and main pressure down, some oil input to guarantee shifting mechanism to low the noise.
3. Because the small load for jump-start, the engine can be started at middle position, shorten the starting time, saving the energy, to facilitate the start of engine at low temperature.
4. The valve has wide range of adjustment, no stroke of liquid pressure, decrease of vibration, and decrease the pulse of main pressure, stable on pressure meters.

MJ-20B model of to-and-for air pump for plasma Purpose and Features:
The pump is adopted to transport various liquid of viscidity and usual causticity, with extensive usage on dye, chemical industry, food, etc. which has dynamic with compressing air, without electricity, so, with the feature of anti- explosion, safety and overload operation; it has no hard pieces to avoid attrition, all motion pieces supported with air-proof ring, with the feature of long life and simple maintain. Through the control on air input and step less adjustment on flow and pressure output, it could be adopted on the transport of liquid with usual changing on flow, pressure and viscidity. Because the pump has great absorb on vacuum, compare to the other products, it has great absorb on plasma, condense plasma of 35000-42000 granularity (JND tester on viscidity is No.4, rotator side). The working position can be vertical or horizontal.

  MJ-20 Type Series Pneumatic Pulp Delivery Bump applied the operating requirement of domestic or imported Round Net Printing Machine, that were imported from Netherlands, Australia, Japan. The installation mode can be horizontal, or vertical.

 
 
Auto control tank:
Every set of round net printing machine has collocate one set pneumatic control tank, and the operating principle is: liquid level probe detect the liquid level of the pulp, and pass the signal to the control tank through 24V DC, by the electronic component, the signal is amplified, control the electromagnetic brake of the pump to make it work or stop, and put the auto control into action.
