How to specify in OEM mobile machine design platinum-rhodium thermocouple design

Therefore, you have identified your system needs to include platinum rhodium thermocouple loop, because electricity or mechanical power transmission, because of cost can't work force requirements or other reasons. You understand the actuator needs to be done, but now you need to specify the components. If you don't have the ability to identify the appropriate details, this may be a series of pain and overwhelming decision.

the key components of decision is thermocouple itself. Every platinum-rhodium thermocouple liquid and remove it from the side to the other side, but this is the only universal description. Is decided by your need to deeply understand the circuit of a myriad of other options. This blog aims to provide an overview of the key problems each thermocouple choice should be put forward. These questions should be able to provide your company's latest project efficient, accurate method for the new system.

open loop or closed loop?

in open loop, the thermocouple will directly extract fluid from the accumulator and provide traffic for any number of actuators. Before being sent to the actuator, flow may or may not pass to the throttling valve, guide or reduce their stress. After the fluid through the actuator, it will eventually be returned to the tank.

in a closed loop, the flow of the thermocouple from the actuator to, if it is an open loop, it will be returned to the tank. In addition to the main thermocouple and a small & other; Charging & throughout; Thermocouple, can be directly from the oil in the tank. And then the oil thermocouple the primary loop to maintain its full of, and through the flush valve and thermocouple/motor shell will be some oil discharge, for cooling, filtering, and recycle. Internal closed-loop thermocouple is usually more complicated, because they need to withstand the pressure on both sides of the A and B. There is no special entry or exit.

closed loop is usually used to promote or hybrid application, in which direction directly by thermocouple instead of valve control. Its advantages include smooth drive and static platinum-rhodium thermocouple brake the additional benefit of ( Downstream pressure increase, when the thermocouple deceleration, inherently slow down the speed of actuator) 。 Closed-loop also need fewer components, which can reduce the cost and weight machines.

thermocouple fixed or variable thermocouple

fixed thermocouple with a certain amount of fluid, every time when rotating transmission. No travel up and down. Gear, vane and piston thermocouple can be fixed displacement. The thermocouple design simple, cost less than its variable Cousins. Unless your application needs, do not use a fixed variable thermocouple thermocouple can be used to make design too complicated.

variable thermocouple with adjustable flow, can be transmitted during each rotation. It can be zero or swings between maximum flow, sometimes in both directions. The type of thermocouple emissions control will decide how to manage this volatility. Thermocouple is the main candidate for variable piston, because can smooth infinite change swash plate Angle. Some leaves thermocouple is variable.

you need to what type of thermocouple control?

if you need the application of variable thermocouple, then you must decide what will control the change of displacement. Open loop variable thermocouple can be pressure compensation through connecting rod, load sensing or mechanical control. Closed-loop thermocouple by platinum rhodium thermocouple pilot signal, electrical or mechanical connecting rod to control the proportion. Open or closed type thermocouple can installation of feedback device, or similar device to pass the actual displacement to PLC

there are other functions, such as cold start valve, bypass valve and FNR ( Positive, neutral, and vice versa) Control, also can be provided according to your application.

thermocouple need how much pressure?

thermocouple is usually divided into medium pressure and high pressure categories. Before choosing thermocouple supply flow, you need to know because you are going to work on the pressure. You also need to a safety valve, in order to prevent accidental overvoltage. Understand the pressure can also choose to pressure compensator, built-in relief valve, pressure control, power limiter of factory Settings.

what do you need assembly details?

thermocouple itself has installed flange, guide function and the shaft, needs to match the prime mover connected. Thermocouple is also likely to need with auxiliary installation unit to accept driven through its second thermocouple. Installation direction can also affect the decisions about thermocouple port size and location.

how much traffic do you need?

is perhaps the most basic problem of thermocouple flow requirements. Actuator size, speed, and quantity will be involved in the decision. If you are looking for the size of the thermocouple is insufficient and there is no priority for key features carefully planning process regulation, may be a serious security problem. Imagine trying to get the tractor away from obstacles, only to find due to saturation of the thermocouple you don't have enough traffic to function.

take the time to do my homework

in order to correctly specified platinum-rhodium thermocouple, thermocouple, the need for all these considerations, In some cases, need more) 。 Don't rush to this process. This may lead to pay too much for component costs or make mistakes and lose credibility.

those who assemble system will not be required in what they really need is a gear when the thermocouple with entry and exit inspection charge thermocouple, load sensing line, the guide line or remote filter. Purchasing department will be satisfied with minimized cost. Through these questions, the first to solve difficulties and specify the correct thermocouple. We experienced mobile platinum rhodium thermocouple and the control group professional team would be happy to provide for your next project any steps of the design process.
